The maprcli dump cldbnodes command lists the nodes that contain container location database (CLDB) data. For best results, use the -json option when running dump cldbnodes from the command line.
The CLDB is a service running on one or more MapR nodes that maintains the location of cluster containers, services, and other information. The CLDB automatically replicates its data to other nodes in the cluster, preserving at least two (and generally three) copies of the CLDB data. If the CLDB process dies, it is automatically restarted on the node.
Syntax
CLI
maprcli dump cldbnodes

Each year between 10% to 20% of college eligible students "melt away" and fail to show up to begin their college career in the fall, a trend known as "summer melt." The vast majority of these students are low income, minority students who have been accepted to college and have even secured enough financial aid. According to the U.S. Department of Education's 2013 study on summer melt, the lower a student's income, the more likely they are to experience summer melt because they lack the necessary resources and support to succeed in college.
The month of August can be a crucial time for prospective college students as they complete the final steps to be eligible to start classes. Enrollment steps include sending final transcripts, signing up for meal plans, enrolling in classes, completing FAFSA paperwork and reviewing terms of scholarships, getting a physical and immunizations, and providing proof of insurance. Many of these steps are required annually, meaning summer melt is an issue for second and third year college students as well.
Boys Hope Girls Hope of Colorado is working to support local students at risk for "summer melt." The organization supports academically motivated children in need achieve their dreams of earning a college degree via tutoring, counseling, and scholarship assistance. Each student in the Boys Hope Girls Hope program receives support not just in applying for college, but through the enrollment process and all four years of their collegiate career.
"Summer melt occurs for many reasons, but often it is a result of the student needing support through the final enrollment and registration process at their chosen school," stated Mary Fran Tharp, executive director of Boys Hope Girls Hope Colorado. "We see many kids get accepted to college and then spend their summer working to help support their families. When it comes time to complete the long checklist of college enrollment procedures, they get overwhelmed and don't have the assistance needed to help navigate the process. That's where we can help."
Less than 30% of students in the bottom quarter of incomes enroll in a four year college. Among that group less than 50% graduate. In Aurora Public Schools, only 19 out of every 100 high school students go to college with 14 out of 100 returning for sophomore year. Only three out of 100 students will complete college in four years.
"Summer melt is a very real issue in our community," continued Tharp. "You hate to see kids work so hard to get accepted to college and then fail to complete the final steps to begin their collegiate career. The Boys Hope Girls Hope program is unique in that we support our kids from as early as middle school all the way to the day they graduate from college. It is really easy for kids to fall into the 'summer melt' trap, but it is just as easy to help them through these final steps and keep them on track for a college degree."

A question about working with MFT (3.5.1) via the voice commands:
How do I change to different screens without actually performing an action? For example, if I'm staring at any particular screen, I can say "navigation map" and it will act as if I pressed the upper-right corner of the screen and switch to the nav map screen.
How do I do that for the "entertainment", "climate" or "phone" screens? (I know I can just press the respective corner of the screen, but I'm trying to learn how to use this with just voice commands.)

Aspects in astrology
Astrologers work with different tools, but they all use aspects and certainly they use aspects within the tighter orbs. There is no doubt about the effects of aspect combinations. They symbolize interaction between positions in the sky above. There is an aspect when there is a meaningful distance between objects in the chart. There are different kind of aspects. There are major aspects (the so called Ptolemaic aspects) and there are minor aspects. There are soft aspects and hard aspects. Let me give you a list:
0 degree Conjunction
60 degrees Sextile
90 degrees Square
120 degrees Trine
180 degrees Opposition
30 degrees Semi sextile
36 degrees Semi quintile
40 degrees Novile
45 degrees Semi square
51.4 d Septile
67.5 d Semi sesquisquare
72 degrees Quintile
80 degrees Binovile
135 d Sesquisquare
150 d Inconjunct
157.5 d Sesquisquare + semi square
160 d Quatronovile
I use tight orbs, no more than 5 degrees and no more than 2 for midpoints and minor aspects in the natal chart. Considering the minor aspects, the orb for midpoints and the fact that if you want sharp hours of birth, it is also worthwhile to use sharp orbs.
Extend the orb only if there is an object between the two other objects in a -toolarge orb! (There is mostly also a midpoint combination then).

Lady PeinforteLady PeinforteLady PeinforteLady PeinforteLady Peinforte
Lady Peinforte was a seventeenth century noblewoman who sought the power of the Nemesis statue.
She had made the sculpture from the Gallifreyan substance Validium and in doing so, learned much about the Doctor.
She became aware not only of his alien heritage but a great deal more besides. However, the Doctor sent the statue into deep space to protect his secrets.
Peinforte time travelled to the twentieth century, knowing exactly when it was due to return.
She battled both the Cybermen and neo-Nazis for control of Nemesis, finally allowing her physical body to merge with the statue, which absorbed her completely. The statue, now resembling Lady Peinforte, launched itself into space, wiping out the Cybermen completely.
Although clearly a powerful and dangerous enemy, the exact circumstances that led to Lady Peinforte gaining such power are unclear, although the available evidence suggests that she was actually secretly aided by outside sources without her knowledge. An evil woman with arcane power and knowledge verging on witchcraft, at some point in the past, Lady Peinforte acquired a sample of Validium – a living metal created as the ultimate defence for Gallifrey back in the early days of Rassilon and Omega -, which she sculpted into a statue of herself carrying a bow and arrow, describing it as 'immaculate beauty carved in absolute evil'. The exact details of Lady Peinforte's first encounter with The Doctor are unknown, but it is known that it featured a battle between soldiers loyal to Lady Peinforte and Oliver Cromwell's Roundheads, culminating in The Doctor launching the Validium asteroid into space to prevent it from reaching critical mass, Lady Peinforte retaining the arrow while the bow was left in Windsor Castle until it vanished in 1788.

|2014 Grammy Awards|
The Grammy awards are named from the trophy: a small, gilded reproduction of a gramophone.
|Awarded for||Outstanding achievements in the music industry|
|Presented by||National Academy of Recording Arts and Sciences|
A Grammy Award (originally called Gramophone Award) – or Grammy – is an accolade by the National Academy of Recording Arts and Sciences of the United States to recognize outstanding achievement in the music industry. The annual presentation ceremony features performances by prominent artists, and some of the awards of more popular interest are presented in a widely viewed televised ceremony. It is the music equivalent to the Emmy Awards for television, the Tony Awards for stage performances, and the Academy Awards for motion pictures.
The first Grammy Awards ceremony was held on May 4, 1959, and it was set up to honor musical accomplishments by performers for the year 1958. Following the 2011 ceremony, NARAS overhauled many Grammy Award categories for 2012. The 55th Grammy Awards were held on February 10, 2013, at the Staples Center in Los Angeles, California.
The Grammy Awards had their origin in the Hollywood Walk of Fame project in the 1950s. As the recording executives chosen for the Walk of Fame (Tabinda Walk) committee worked at compiling a list of important recording industry people who might qualify for a Walk of Fame star, they realized there were many more people who were leaders in their business who would never earn a star on Hollywood Boulevard. The music executives decided to rectify this by creating an award given by their industry similar to the Oscars and the Emmys. This was the beginning of the National Academy of Recording Arts and Sciences. After it was decided to create such an award, there was still a question of what to call it; one working title was the Eddie, to honor the inventor of the phonograph, Thomas Edison. They finally settled on using the name of the invention of Emile Berliner, the gramophone, for the awards, which were first given for the year 1958.
The gold-plated trophies, each depicting a gilded gramophone, are made and assembled by hand by Billings Artworks in Ridgway, Colorado. In 1990 the original Grammy design was revamped, changing the traditional soft lead for a stronger alloy less prone to damage, made of slumped and reformed pre-war Gibson flat head banjo tone rings, making the trophy bigger and grander. The trophies with the recipient's name engraved on them are not available until after the award announcements, so "stunt" trophies are re-used each year for the broadcast.
As of February 2009, 7,578 Grammy trophies had been awarded.
The "General Field" are four awards which are not restricted by genre.
Other awards are given for performance and production in specific genres, as well as for other contributions such as artwork and video. Special awards are given for longer-lasting contributions to the music industry.
Because of the large number of award categories (78 in 2012), and the desire to feature several performances by various artists, only the ones with the most popular interest - typically about 10 to 12, including the four General Field categories and one or two categories in the most popular music genres (i.e. pop, rock, country, rap) - are presented directly at the televised award ceremony. Other awards are presented in a pre-telecast ceremony earlier in the afternoon of the Grammy awards ceremony.
On April 6, 2011, The Recording Academy announced a drastic overhaul of many Grammy Award categories for 2012. The number of categories were diminished from 109 to 78. The most important change is the elimination of the distinction between male and female soloists and between collaborations and duo/groups in various genre fields (pop, rock, R&B, country, and rap). Also, several categories for instrumental soloists were discontinued. Recordings in these categories now fall under the general categories for best solo performances.
The most eliminations occurred in the roots category. Up to and including 2011, there were separate categories for various regional American music forms, such as Hawaiian music, Native American music and Zydeco/Cajun music. Due to the consistently low number of entries for these categories, The Recording Academy decided to combine all these music variations into the new Best Regional Roots Music Album, including polka, which lost its own separate category in 2009.
In the same genre field, the traditional and contemporary blues categories and the traditional and contemporary folk categories each were consolidated into one per genre, due to the number of entries and given the challenges in distinguishing between contemporary folk and Americana, and contemporary and traditional blues. In the world music genre field, the traditional and contemporary categories have also been merged.
In the classical genre field, its main category Best Classical Album has been discontinued because most recipients in this category had also won in one of the other classical categories for the same album. Classical recordings are now eligible for the main Album of the Year category.
There are also a few minor name changes to better reflect the nature of the separate categories. It was determined by the Recording Academy that the word "gospel" in the gospel genre field tends to conjure up the images and sounds of traditional soul gospel and leaves out the current contemporary Christian music (CCM). Therefore the genre field and some categories have been renamed as Gospel/Contemporary Christian Music.
Record companies and individuals may submit recordings to be nominated. Nominations are made online and a physical copy of the work is sent to the National Academy of Recording Arts and Sciences. Once a work is entered, reviewing sessions are held, by more than 150 experts from the recording industry, to determine whether the work is eligible and entered in the correct category for official nomination.
The resulting list is circulated to all NARAS members, each of whom may vote to nominate in the general field (Record of the Year, Album of the Year, Song of the Year, and Best New Artist) and in no more than nine out of 30 other fields on their ballots. The five recordings that earn the most votes in each category become the nominees. There may be more than five nominees if there is a tie in the nomination process.
Whereas members of the Academy of Motion Picture Arts and Sciences are generally invited to screenings or are sent DVDs of movies nominated for Oscars, NARAS members do not receive nominated recordings.
After nominees have been determined, final voting ballots are sent to Recording Academy members, who may then vote in the general fields and in no more than eight of the 30 fields. NARAS members are encouraged, but not required, to vote only in their fields of expertise. Ballots are tabulated secretly by the major independent accounting firm Deloitte Touche Tohmatsu. Following the tabulation of votes the winners are announced at the Grammy Awards. The recording with the most votes in a category wins and it is possible to have a tie. Winners are presented with the Grammy Award and those who do not win are given a medal for their nomination.
In both voting rounds, Academy members are required to vote based upon quality alone, and not to be influenced by sales, chart performance, personal friendships, regional preferences or company loyalty. The acceptance of gifts is prohibited. Members are urged to vote in a manner that preserves the integrity of the academy.
The eligibility period for the 2013 Grammy Awards was October 1, 2011 to September 30, 2012.
Prior to 1971, the Grammy Award ceremonies were held in different locations on the same day. Originally New York City and Los Angeles were the host cities. Chicago joined being a host city in 1962, and then Nashville became the fourth location in 1965.
The 1971 ceremony, held at the Hollywood Palladium in Los Angeles, was the first to take place in one location. The ceremony was then moved to Madison Square Garden's Felt Forum in New York City, and then Nashville's Tennessee Theatre in the following two years. Then from 1974 to 2003, the Grammys were held in various venues in New York City and Los Angeles. Notable locations included New York City's Madison Square Garden and Radio City Music Hall; and Los Angeles' Shrine Auditorium, the Staples Center and the Hollywood Palladium.
In 2004, the Staples Center became the permanent home of the award ceremonies. The Grammy Museum was built across the street from Staples Center in LA Live to preserve the history of the Grammy Awards. Embedded on the sidewalks at the museum streets are bronze disks, similar to the Hollywood Walk of Fame, honoring each year's top winners, Record of the Year, Best New Artist, Album of the Year, and Song of the Year.
With 31 Grammy Awards, Sir Georg Solti is the artist with the most Grammy wins. Alison Krauss is the biggest winner among female artists with 27 awards. U2, with 22 Grammy Awards, holds the record for most awards won by a group.
The Grammy Awards has received criticism from various recording artists and music journalists.
When his band Pearl Jam won a Grammy in the category Best Hard Rock Performance in 1996, singer Eddie Vedder commented on stage: "I don't know what this means. I don't think it means anything." Glen Hansard, leader of the Irish rock group The Frames, stated in 2008 that the Grammys represent something outside of the real world of music "that's fully industry based." He said he wasn't that interested in attending that year's ceremony, even though he had been nominated for two different awards. Maynard James Keenan, lead singer of metal band Tool, did not attend the Grammy Awards ceremony to receive one of their awards. He explained his reasons:

can also group the tools to create a tool GigaStream. You can apply egress filters in tool ports. Refer to the Egress Filters section for more details.
- Sources: Displays the configured ports. You can edit the ports and create port groups from sources. Do not use fan out port as source port in policy.
- Filters: Displays the available filters. You can create a new template from the Filters option. Starting in software version 5.9, you can use advanced filters for creating the filter rules.
- Packet Transformations: Displays the supported packet transformation options. You can also create a template with the required Packet Transformation option.
- Visualize: You can select multiple policies and click Visualize to compare the policies.
Note: You can create policies by navigating to Actions > Create Policy from all of the tabs listed above. You can view the health status of the ports, tools and policies when creating the policy.
You must have the following licenses:
|GigaSMART Packet Slicing
|GigaSMART Header Addition
|GigaSMART Header Stripping
Refer to the Rules and Notes for Orchestrated Configurations section before creating the policy.
To create orchestrated policies:
- On the left navigation pane, click on and under Physical > Orchestrated Flows> Out-of-Band Flows.
- Click Create Policy. The Create Policy wizard is displayed. You can specify a name for the policy.
- Select Sources to select the available source ports or port groups.
- Click Select Tools to select the required tool ports (port type: tool port or hybrid). You cannot select a port that is already used. You can also associate a new tool using the Create New Tool option.
- Create the policy with the required rules. You can define the required filters and criterion in the rule.
- If you have configured multiple filters in a rule, then the traffic will be filtered only if all the filter rules are true.
- If you have configured multiple criterion in a rule, then the traffic will be filtered even if one of the criteria is true.
- Select the required packet transformation option. You can combine multiple packet transformation options with in a single rule. The GigaSMART packet transformation operations are performed in parallel.
- Click on the edit option next to the Processing Engine option to select the required GigaSMART engine ports for your rule. If you do not select the engine ports, then they will be automatically selected.
- For policies created based on multicluster topology, you must manually select the engine ports, as automatic allocation is not supported.
- For policies created based on single cluster topology, automatic allocation of engine ports is supported. However, only engine ports that have not been already used will be allocated.
- Enable the Prioritize Rules check box to create priority-based policy.
- Click the Tags option to associate the policy to tags. Refer to Tagging and RBAC Support section for more details.
- Click Validate to validate the policy. You can either:
- Click Save to save the policy. You can deploy the saved policies later.
- Click Deploy to deploy the policy.
Note: You can configure the sources, tools and policies in any sequence you want.
Note: If a port (port type: network or hybrid) is already used as a source port in any of the following standard GigaVUE‑FM configurations, then those ports will not be listed in the drop-down:
|5G CUPS solution
However, you can view all the ports in the Ports page.
Note: You can select Drop to drop the packets without selecting the tools. Refer to the Drop Rules section for details related to drop rules.
Note: You can create a policy with multiple rules. With in each rule, you can configure multiple criteria and multiple filters and use them together with the packet transformation options.
Note: Engine ports that have not been used in standard GigaSMART operations will only be available for selection. You cannot edit or delete an engine once a policy is deployed. However, you can remove the packet transformation and add the packet transformation option with a different engine.
Note: Use the Everything Else option to configure the shared collector. Refer to the GigaVUE Fabric Management Guide for details on Shared Collector.
The policy thus created is listed together with the list of policies. You can edit, delete, deploy and undeploy a policy, as required.
Tagging and RBAC Support
Role Based Access Control (RBAC) in GigaVUE-FM controls the access privileges of users and restricts users from either modifying or viewing unauthorized data. In Orchestrated Configurations, RBAC controls the accessibility of the users to the policies based on the tags. Tags can be either RBAC tags or aggregation tags. Multiple tags can be assigned to policies and rules.
Note: RBAC tags are supported only at the policy level. The orchestration wizard allows RBAC tags to be applied at the rule level as well, though it is not supported in this release.
To associate policies to tags:
- Click the Tags option at the policy level. You can associate tags either at the time of creating a policy or edit an existing policy.
- Select the required tag keys and tag values.
- Click Save.
Note: The tag key and the associated tag values must be created in advance in GigaVUEFM. Refer to the "Tags" and "Role Based Access Control" sections in the GigaVUE Administration Guide for more details
Once you associate the policy to a tag, only users with fm_super_admin role or users with read/write access to the Traffic Control Management category can access the policies.
You can use the Drop option in the 'Create Policy' wizard as the destination to drop a packet. For a drop rule to pass a packet, it must be used together with a pass rule or with the 'Everything Else' rule, such that the packets that do not match the drop criteria will be forwarded to the tools.
In orchestrated configurations, there are no rule priorities for pass rules. However, the following is the order of priority for prioritized and unprioritized drop rules together with the pass rules:
- Prioritized drop rules
- Pass rules
- Unprioritized drop rules
- Default collector
A drop rule, by default, has lower priority than the pass rule and higher priority than 'Everything else'. Therefore, a drop rule will drop the traffic before the traffic gets passed to the destination of the 'Everything Else' rule. However, a prioritized drop rule has the highest priority amongst all the rules in a policy and will drop matching traffic before any other policy rule can process that traffic.
Consider a scenario in which the intent is to drop packets with VLAN 101 and pass packets with IP version 4. Based on the default settings, if there is only IPv4 traffic on the source side, packets with VLAN Id 101 will not be dropped because pass rule has higher priority than the drop rule. To choose 'Drop' as high priority within the policy, you must prioritize the drop rule by checking the 'Prioritize Rule' option.
Note: To prioritize the drop rules in deployed policies, you must first undeploy the policy.
Starting in software version 5.11.00, you can import and export an orchestrated policy in YAML format. This allows you to bulk deploy the policies.
The following are the advantages of importing and exporting policies:
- Retrieve a policy that was deleted unintentionally.
- Deploy the policy in another device.
- Re-deploy a policy in the device after GigaVUE-FM is upgraded to a new version (in case of issues in the existing solution).
The YAML file contains the following information:
- Packet Transformation
The below is the Import and Export Policy sample template of a YAML file. You can use the following sample template as a reference while building a policy in YAML format.

Rules and Notes
Refer to the following rules and notes:
- You can export policies that either deployed or undeployed. However, when you import a policy, it will be in undeployed status. You must manually deploy the imported policy.
- You cannot import or export the egress port filters in a policy. You must manually apply them.
- When you export a policy that has GigaStream, port groups and other such groups, you must ensure that those groupings exist when you import the same policy. This also applies to tools that were created through the tool wizard.
- Port types involved in a policy that is exported must not be changed when trying to import the same policy.
- If templates were used to create a policy that was exported, then those templates must remain when importing a policy.
- You can import and export several policies in one operation.
Import and Export Orchestrated Configuration
To export a policy:
- In the Policies page, select the policy that must be exported.
- Select Actions and click Export Policy. The policy is downloaded as an YAML file.

Killifish - Nothos Killifish
The Nothobranchius killifish come from East Africa. They are annual fish, meaning they live for around a year. This is because in the wild, their habitat consists of temporary pools. These pools are created by seasonal rains and dry up when drought comes. Thus the fish die having left behind their eggs buried in the river/lake bed. During the dry period the eggs develop and when the rain returns, filling up the pools again, the embryos hatch.

Because of the unpredictable weather, the fry grow fast, reaching maturity within a few weeks and reproduce. Not all survive but this does not end the population. The eggs go through several distinct stages in their growth, including resting periods called diapause. Some of these embryos will either stop for a while, or at least slow down significantly in their development. Because of this some will not be ready to hatch for some time after their siblings and in this way there are always eggs ready to hatch whenever the rains come.

The descriptions on these fish vary greatly. As a general description goes, they have slightly compressed elongated bodies with the anal fin and dorsal fins set well back and wide caudal fins with a round edging. Their coloration varies from pink, white, silver, maroon, red to orange, yellow and many other colors. The East African annual fish are thought to be one of the most beautiful fish in the world. More often than not, the colors are combined, creating beautiful coloration. Among the different varieties of killifish there is the, Guentheri from Zanzibar Island, rachovii from Mosambique and the Eggersi from Tanzania.

The Nothobranchius killifish prove to be interesting to fish hobbyists. Caring for the Nothobranchius is not all that hard but they do require a little extra attention than the common Aphyosemion Killifish species.
A minimum aquarium of 10 gallons (37.8 liters) is required for every three fish of any of these species. They prefer soft water, with a pH of 6.0 to 6.5 and a water temperature of 70-80 F (21-27 C). Decorations, including live aquarium plants and rocks, set up in a way that would provide shelter when needed helps in making an ideal home for these fish.
Nothobranchius rubroreticulatus Killifish

Nothobranchius rubroreticulatus
They are considered to be peaceful fish and can be kept with other killis as well as other fish that tolerate the same water conditions. More than one male is not advised to be kept in a 10 gallon aquarium as they tend to fight. If more than one male is to be present in the aquarium then it should be 20 gallons (75.7 liters) or more. The fish of the Nothobranchius species grow between 1.5 - 2.5 inches, depending on the specific species.
A wide variety of food is accepted, although small live food, like brine shrimp and grindal worms is much more preferred.
To identify the genders, notice that the male is the more colorful one and the female is more of a silvery colour or sometimes, with less colour and duller than the male.
To breed them, try and imitate their natural habitat the best you can. This, as in other fish species, helps encourage spawning. Using peat for substrate in the aquarium, they will breed and bury their eggs in it, as they will with mud that is used in the wild. The pair will dive in to the substrate and the male will press the female against a hard surface of the peat, in this way releasing the sperm and eggs. This process will be repeated a couple of times within a few minutes, resulting in hundreds of eggs being laid. The peat should be taken out and left to dry. Not too dry or the eggs will die, just enough to leave the peat damp. Thereafter place it an air tight package (so that it cannot get any dryer) and leave it to stand for about three months.

By doing this you will be mimicking the drought period in their natural habitat. It is in this dry period which the killifish eggs will develop. When the "drought" is over the aquarium in which the fry is to be raised should have peat for substrate and java moss for cover. The peat should be kept wet in the tank for a week or so and whatever fry it contains removed. The peat should again be taken out and dried for a week. Thereafter wet again for a week or so and by this manner the process should be repeated until you are positive that there are no eggs left. It takes a long time and can be a hard process. Any questions can be put to Tom on the Fishlore forum.

Pin Configuration Examples
This section presents the details of the three Pin Configuration register programming examples that were mentioned in the introduction.
All three examples use the same set of four DAC widgets from an HD Audio codec, but each example configures the same four widgets in a different way to form a different set of audio rendering devices. Each DAC widget connects to a pin widget that represents a stereo output jack. The motherboard or system vendor configures the pin widgets by choosing appropriate settings for the Pin Configuration registers that belong to the pin widgets.
The HD Audio codec contains four DAC widgets that are identical to the one shown in Figure 22.
Figure 22. A single-pin analog rendering device
In the example in Figure 22, the DAC widget has a gain control and connects to a pin widget that has a mute control.
Three different motherboard or system vendors can use the same set of four widgets to form the following devices:
 - Example 1. The first vendor can choose to use three of the pin widgets to form a six-channel rendering device (such as a 5.1 surround speakers configuration, as described in the previous section titled "Speaker Configurations") and use the fourth pin widget for an independent headphone device.
 - Example 2. The second vendor can choose to use the four pin widgets to implement an eight8 channel rendering device (such as a 7.1 home theater speakers configuration) without headphone functionality.
 - Example 3. The third vendor can use three of the pin widgets as three independent two-channel rendering devices (such as stereo speakers) and use the fourth pin widget as an independent headphone device.
For each of these three systems, the system integrator (OEM or ODM) programs the system BIOS to load values into the codec's Pin Configuration registers that describe the audio devices in the system. The details of these three examples are presented in the following sections.
Example 1
The first vendor configures the four pin widgets by loading the settings shown in Table 4 into the four Pin Configuration registers that belong to the pin widgets.

Pins A, B, and C drive a set of six speakers, and pin D drives a set of stereo headphones.
Pins A through C belong to the same pin-widget association. Hence, they operate together as a single device. The topology parser recognizes the sequence numbers (0, 1, 4) for pins A through C as identifying a 5.1 surround sound speakers configuration, as described in the previous section titled "Speaker Configurations."
The Default Association number for the headphones device is 0xF. By convention, the UAA HD Audio class driver treats all pin widgets with Default Association number 0xF as single-pin devices. Although these pin widgets have the lowest priority in hardware resource conflicts, pin D in this example has a dedicated DAC widget and no resource conflicts with any other pin widgets. Hence, a low priority cannot possibly cause pin D to lose any hardware resources. However, if pin D did have a resource conflict, assigning the pin a higher priority (that is, a Default Association number less than 0xF) would be necessary to ensure that the UAA driver assigns the pin the resources that it requires to function as a device.
In accordance with the previously described color-coding recommendations, the jack colors for pins A, B, and C are as follows:
 - Pin A, which transmits channels 0-1 (FL and FR speakers), is green.
 - Pin B, which transmits channels 2-3 (FC and LFE speakers), is orange.
 - Pin C, which transmits channels 4-5 (SL and SR speakers), is gray.

Pins A, B, and C each drive a set of stereo speakers and pin D drives a set of stereo headphones.
The Default Association number for pins B through D is 0xF, which means that each operates as a single-pin device. In addition, each of pins B through D has dedicated hardware resources that it does not share with other pins. Hence, none of these pins needs a Default Association number lower than 0xF.
 In contrast, pin A in this example shares a hardware resource, such as a DAC widget, with some other pin widget (not shown in Table 6). To ensure that the UAA HD Audio class driver assigns the contested resource to pin A rather than to the other pin widget, the BIOS sets the Default Association number for pin A to 0x


the code above, I used so-called magic numbers for gravity acceleration, maximum vertical speed (terminal velocity?) and jump speed. You'd be better off defining some variables in the create event of the player so you could easily edit those values (and know the meaning of those numbers by reading the variable's names).
Move and Collide script
Finally, we're going to code movement and collisions! If the player has an horizontal speed of 7.43 pixels, we round it to 7, keep the remainder for the next frame, and for 7 times we check for collisions before moving it by one pixel after each check. This ensures we get pixel perfect collisions.
Granted, this might get expensive for very high resolution games where the player needs to travel hundreds of pixels per step (with hundreds of collision checks per step) but for low resolution games, it works pretty damn well. You could come up with different movement code if you wish. Let me know in the comments what you came up with then.
Notice the slope code inside the horizontal movement. This is what lets us stick the player to slopes when going up or down, without changing player states or messing with vertical speeds.
It basically say "if the object is inside a slope, get it outside by pushing it upwards" (going up a slope) and also "if there's no ground below but there's a slope just 1px below, stick to it" (going down a slope).
// Movement/Collision X
xvel_fract += xvel;
xvel = round(xvel_fract);
xvel_fract -= xvel;
xdir = sign(xvel)
 if!place_meeting(x + xdir, y, oWall)
 x += xdir
 // Inside a slope (must go up)
 while collision_point(x, y - 1, oSlope, true, true)
 if can_go_up()
 // Let's go back (outside slope) and stop
 x -= xdir
 xvel = 0
 xvel_fract = 0
 // On a slope going down
 while!on_ground() && collision_point(x, y + 1, oSlope, true, true)
 xvel = 0
 xvel_fract = 0
// Movement/Collision Y
yvel_fract += yvel;
yvel = round(yvel_fract);
yvel_fract -= yvel;
ydir = sign(yvel)
 // Going down
 if ydir
 if!on_ground()
 y += ydir
 yvel = 0
 yvel_fract = 0
 // Going up
 if can_go_up() &&!collision_rectangle(bbox_left, bbox_top, bbox_right, bbox_top, oSolid, true, true)
 y += ydir
 yvel = 0
 yvel_fract = 0
And this is the can_go_up script
///_USER_ can_go_up()
///_USER_ return true if player's not colliding with walls/ceilings
return!collision_rectangle(bbox_left, bbox_top - 1, bbox_right, bbox_top - 1, oWall, false, true)
There's plenty of space for optimizing this script and we'll see how in the next articles.
On Slopes and the oSlopeWall object
Because the player must be able to go inside slopes, we treat them separately from the usual solids/walls. Due to this difference in collision checking, we need to ensure we place the oSlopeWall at the start, in the middle and at te end of our ramps.
Incorrect slope placement in the room editor.
The player will hit these oWall blocks and will jump off the first slope on the left when going down to the left.
Correct slope placement in the room editor.
The player will correctly travel upward and downward without ever changing state, jumping or getting stuck.
In the next article
In the next article we'll talk about jump-through platforms and we'll refactor the code to solve some minor issues. Keep in mind that some limitations of this system can be either avoided altogether with sensible level design or manually fixed via code, case per case. This engine, as of now, isn't really advanced, yet we briefly touched topics such as state machines and slopes.
Please leave a comment
If you notice any oddity, please let me know in the comments. I'm curious about what would you want me to fix. I'm already planning on some fixes and improvements but maybe you noticed something that I missed.

Cascading StyleSheet (CSS) Link Text Formatting in NetObjects Fusion
When you add a link to some existing CSS-formatted text, you might get unexpected formatting results. For best results, set only color properties for CSS link styles.
Check your CSS link formatting settings in two places:
- Style View, Text tab, and
- Page View, on the Menu select Text, Edit Text Styles.
In each of those areas, set only the desired color. Leave all other settings on "Automatic." Why?
- If you define a font size for link text, the link style font size will override the font size of the page text when you make a link in your page.
- This behavior is probably NOT what you want.
To check your link style settings for each possible CSS style level, in Page View's Text Styles dialog, check all the available Scope settings. If you do that, you will get no odd formatting with text links.

Classification of Nouns
Nouns are categorized by vowels and consonants they include. For the consonants they include nouns are categorized in two groups: 15 Nouns and 16 Nouns. For the vowels they include nouns are categorized in 5 groups: a, ä; å, ø; o, ö; u, y; i, e.
15 Nouns: the first consonant of these nouns are h, j, m, n, r, s, s'
16 Nouns: the first consonant of there nouns are c, d, l, p, t, v, l'
Categorizing by vowels depends on how many syllable noun has and what is the vowel in the syllable we have to use.
If a noun has 2 syllable we use the vowel of the second syllable
If a noun has 3 syllable we use the vowel of the third syllable
If a noun has 4 syllable we use the vowel of the second syllable
ıf a noun has 5 or more syllable we use the vowel of the syllable before the last syllable.
Vowel in a syllable can be a single vowel or a diphthong. If the syllable contains a diphthong, we choose the vowel we will use according to following rules:
If there is "u" or "y" we use them,
If there is a back vowel and "i" we use the back vowel,
If there is a front vowel and "i" we use "i",
In other diphthongs we use the first vowel.Definite Articles
Vi Söllidäävin has10 definite articles. All definite articles are 2 letters. First is a consonant, second a vowel.
If a noun is a 15 noun, the first letter of the article is "v"
If a noun is a 16 noun, the first letter of the article is "s"
we add the vowel according to the rules above to these consonants and make the article.
E.g.: tyycciön has 2 syllable. we will use the second syllable and the vowels in it are i and ö. "ö" is a front vowel this means we will use "i". And it is a 16 noun. With these knowledges the article is "si". Si Tyycciön.
More examples: vo riol, su vuun, va raceslain, ve hiynnen.
We have to use the root word to decide the article of the noun. In a sentence if a noun takes a prefix, that noun does not take article. We use definite article when the noun does not take prefixes and indefinite article.Indefinite Article
Vi Söllidäävin has 1 indefinite article and it is a suffix. We add "-me" to the noun. And if a noun takes this suffix, it does not take definite article.
E.g.: noidame → a love

New display sheets that can be cut into any shape with scissors
(Nanowerk News) A research group led by Masayoshi Higuchi, the leader of the Electronic Functional Macromolecules Group, Research Center for Functional Materials, NIMS, developed new display sheets that can be cut into any shape with scissors. As you can cut this display into any shape you like, and attach it on the surfaces of things that has complex shapes such as clothing and buildings, the display is expected to meet diverse display needs, which cannot be achieved by conventional display technologies.
Display sheet being cut with scissors (left). The sheet's display function is intact even after being cut into smaller pieces (right). (click on image to enlarge)
Common displays (including LCD and OEL) that are capable of showing letters and images are equipped in most of the electronic devices we use in our everyday life. Also, there are increase in demand for displays that can present information in a variety of forms, such as digital signage and wearable devices. However, it is impossible to cut these conventional displays into various shapes because it is necessary to seal the contents of both LCDs and OELs, for example, as the LCDs contain liquid and OELs are susceptible to water, oxygen and other impurities. Moreover, since these displays require continuous power supply to maintain their functions, they must be connected with a power source or a drive. Due to these requirements, it had been difficult to develop cuttable displays using existing technologies.
The research group developed display sheets that can be cut into any shape with scissors, using a polymer with electrochromic properties (organic/metal hybrid polymer). This polymer can be sprayed onto a flexible substrate to form a coating layer stable against moisture and oxygen. In addition, the new display requires only a few seconds of electrical input to switch visual information, and the display will last even after power supply is discontinued. Accordingly, we successfully developed a sheet type display device capable of functioning while being detached from a power source and after being cut into a shape.
In future studies, we aim to increase the display area and make it capable of showing multicolor. We also intend to propose a concept called "new life style in which people can enjoy changeable colors in everything." In this proposal, we envision the application of the new technology in society whereby people can freely change the colors of various objects/items, e.g. windows, the interior or exterior of motor vehicles and buildings, umbrellas and sunglasses, and can display letters and symbols as appropriate.
This study was conducted under the project "Ultrafast, ultralow-power, ultralarge-area electrochromism" (Masayoshi Higuchi, Research Director) in the research area "Innovative nano-electronics through interdisciplinary collaboration among material, device and system layers" (Takayasu Sakurai, Research Supervisor) as part of the Strategic Basic Research Programs (specifically the CREST program) sponsored by the JST.

Keywords: Justice, Pancasila, Aristotle's Theory
The basis of Pancasila justice is found in points 2 and 5, which reads the second principle of just and civilized humanity and the fourth principle of justice for all Indonesian people. Fair and civilized human values, that awareness of attitudes and behaviors that are in accordance with moral values in living together on the basis of the demands of conscience by treating things as they should. Humans need to be treated according to their dignity and dignity, as God's creatures who are equal and have the same rights and human obligations. Based on this value, there is absolutely recognition of human rights. The value of social justice for all Indonesians implies both the basis and the goal, namely the achievement of a just and prosperous Indonesian society both physically and mentally. Based on this value, justice is a very basic value that is expected by all nations. The expected Indonesian state is an Indonesian state that is just. Justice is described fundamentally by Aristotle, namely to know about justice and injustice, three main things must be discussed, namely what actions are associated with the term, what justice means, and between the two extreme points whether justice lies

The Czech Warmblood is a riding horse that, as its name implies, originates from
The Czech Warmblood is a sturdy horse. It is speedy and agile. Most Czech Warmbloods are colored bay and chestnut, although some are gray and black; and still others are seen in Isabella or dun. The average height of a Czech Warmblood is 16 hands (64 inches, 163 centimeters).
Personality and Temperament
This energetic, animated, and alert horse breed has an aristocratic air. Its temperament, however, is suited for the discipline of racing.
History and Background
The original Czechoslovakian horses were all of the Warmblood type. To improve them, breeders introduced Spanish and Oriental horses and, at the start of the 20th century, English blood. The breeding of these horses was also influenced when Empress Maria Theresa issued an edict about horse breeding in 1763.
During World War I, Thoroughbreds and

One of the study's authors was Michael Arts (PhD), an expert on using lipid-based biochemical tracers (e.g., fatty acids) to assess how organisms respond to stress and also to reveal how food webs function.
He is a professor in the Department of Chemistry and Biology at Ryerson University in Toronto, OntarioListen
The research was published this month in Nature Communications.
Using carbon tracing, the team was able to establish a clear link between the size and condition of fish and the degree of forestation around the lake and it's watershed.
They found that water runoff from forested areas cantained nutrients that were deposited around the point where streams entered a lake. Those nutrients fed bacteria, which fed zooplankton which continued up the food chain to fish.
They found the more heavily forested an area was, the healthier the fish and fish population. In fact, using the carbon tracing, they found in heavily forested areas that up to 66% of some fishes biomass could be traced back to origins on the land, and not from their aquatic environment.
Professor Arts says this study shows that in order to protect freshwater ecosystems, one must also take into account the activities on land around that water system.
He points out freshwater fishing is vital in many areas of the world, and that preservation of surrounding forest areas will enable that fish resource to be viable and sustainable.

Hot dogs didn't come to America until the 1860's when a German immigrant began selling them off a cart in New York's Bowery.
Apple pie came to America courtesy of England – via Geoffrey Chaucer's recipe. But apples originated from Asia – which is also where fireworks were created.
Baseball, our national pastime, may actually trace its roots back to Egypt – where the first use of a bat and ball were discovered.
Finally, America didn't invent the idea of democracy – that hails from Greece. In fact, the word democracy isn't even in the Declaration of Independence.
There are many fine traditions associated with July 4th. Celebrating them binds us together as a nation.
But origin stories do us one better, they connect us more broadly to the world and remind us of our shared humanity.
Hope you had a wonderful 4th of July.

OK, so here is the deal.
In my language I have some commands, say
XYZ 3 5
GGB 8 9
HDH 8783 33
And in my Lex file
XYZ { return XYZ; }
GGB { return GGB; }
HDH { return HDH; }
[0-9]+ { yylval.ival = atoi(yytext); return NUMBER; }
\n { return EOL; }
In my yacc file
start : commands
commands : command
 | command EOL commands
 command : xyz
 | ggb
 | hdh
 xyz : XYZ NUMBER NUMBER { /* Do something with the numbers */ }
 etc. etc. etc. etc.
My question is, how can I get the entire text
XYZ 3 5
GGB 8 9
HDH 8783 33
Into commands while still returning the NUMBERs?
Also when my Lex returns a STRING [0-9a-zA-Z]+, and I want to do verification on it's length, should I do it like
rule: STRING STRING { if (strlen($1) < 5 ) /* Do some shit else error */ }
or actually have a token in my Lex that returns different tokens depending on length?

If I've understood your first question correctly, you can have semantic actions like
{ $$ = makeXYZ($2, $3); }
which will allow you to build the value of command as you want.
For your second question, the borders between lexical analysis and grammatical analysis and between grammatical analysis and semantic analysis aren't hard and well fixed. Moving them is a trade-off between factors like easiness of description, clarity of error messages and robustness in presence of errors. Considering the verification of string length, the likelihood of an error occurring is quite high and the error message if it is handled by returning different terminals for different length will probably be not clear. So if it is possible -- that depend on the grammar -- I'd handle it in the semantic analysis phase, where the message can easily be tailored.

If you arrange for your lexical analyzer (yylex()) to store the whole string in some variable, then your code can access it. The communication with the parser proper will be through the normal mechanisms, but there's nothing that says you can't also have another variable lurking around (probably a file static variable - but beware multithreading) that stores the whole input line before it is dissected.

I guess maybe I wasn't that clear, but I have something like HEADER BLOCK1 STUFF BLOCK1END BLOCK2 STUFF BLOCK2END Where BLOCK1 and BLOCK2 match the same rule. What I need is the entire text of BLOCK1 at the time that I match BLOCK1. The simplest, but annoying way, is just to have all of the rules have a value of string, i.e. from my example %type xyz Then for every rule I would have to put xyz: XYZ NUMBER NUMBER { $$ = "XYZ" + $2 + $3; } Which overtime can get very annoying. – DevDevDev Aug 6 '09 at 17:37

As you use yylval.ival you already have union with ival field in your YACC source, like this:
%union {
 int ival;
Now you specify token type, like this:
%token NUMBER
So now you can access ival field simply for NUMBER token as $1 in your rules, like
xyz : XYZ NUMBER NUMBER { printf("XYZ %d %d", $2, $3); }
For your second question I'd define union like this:
%union {
 char* strval;
 int ival;
and in you LEX source specify token types
%token STRING;
%token NUMBER;
So now you can do things like
foo : STRING NUMBER { printf("%s (len %d) %d", $1, strlen($1), $2); }

This gives a segfault on matches to string. – schwiz Nov 14 '12 at 19:36

The Koman Hydroelectric Power Station is a large hydroelectric power station, for which a dam on the Drin River was built. The dam is near the settlement of Koman, northern Albania. It is the second of three dams on the Drin River; the Fierza Hydroelectric Power Station upstream, and the Vau i Dejës Hydroelectric Power Station downstream. The dam, 130m tall, was completed in 1985 and the reservoir was filled with water at full capacity in 1986.
Completed in 1986, the power station consists of four turbines of French origin with a nominal capacity of 150 MW each, totalling the installed capacity to 600 MW.

Oral and graphic expressions of the Wajapi
Inscribed in 2008 (3.COM) on the Representative List of the Intangible Cultural Heritage of Humanity (originally proclaimed in 2003)
- Wajapi communities in northern Amazonia have a long history of producing and using vegetable dyes to adorn their bodies with geometric motifs and symbols. Motifs of the jaguar, anaconda, butterfly and fish animate the worldview and oral traditions of the Wajapi.
- © Dominique Tilkin Gallois
The Wajapi of the Tupi-guarani cultural-linguistic group are indigenous to the northern Amazonian region. Some 580 Wajapi live in 40 small villages on a specially designated territory in the state of Amapá. The Wajapi have a long history of using vegetable dyes to adorn their bodies and objects with geometric motifs. Over the centuries, they have developed a unique communication system – a rich blend of graphic and verbal components – that reflects their world-view and enables them to hand down knowledge about community life.
This graphic art is known as kusiwa and its designs are applied with red vegetable dyes extracted from the roucou plant mixed with scented resins. The Wajapi consider that the technical and artistic proficiency required to master the drawing technique and the preparation of the dye cannot be attained before the age of forty. Commonly recurring motifs include the jaguar, anaconda, butterfly and fish. Kusiwa designs refer to the creation of humankind and come alive through a rich corpus of myths. This body art, closely linked to Amerindian oral traditions, possesses multiple meanings on socio-cultural, aesthetic, religious and metaphysical levels. Indeed, kusiwa constitutes the very framework of Wajapi society and is endowed with significance extending far beyond its role as a graphic art form. This coded repertory of traditional knowledge is perpetually evolving as indigenous artists are constantly reconfiguring the motifs and inventing new patterns.
Although the Wajapi live on their protected territory, their traditional lifestyle, including the practice of kusiwa, is in danger of losing its symbolic significance and may even disappear altogether. Such a loss would drastically alter the community's social and cosmological reference points. The principal threats stem from disinterest on the part of the younger generation and the decreasing number of Wajapi proficient in the kusiwa repertory.
These videos (and many more) can also be consulted through the UNESCO Archives Multimedia website
Safeguarding project (07-2006/11-2008)
Wajapi communities in northern Amazonia have a long history of producing and using vegetable dyes to adorn their bodies with geometric motifs and symbols. Motifs of the jaguar, anaconda, butterfly and fish animate the worldview and oral traditions of the Wajapi.
The safeguarding project aims at supporting the Wajãpi in their efforts to document their skills, experiences and knowledge related to their manifold oral and graphic expressions as they are embodied, most prominently, in the kusiwa graphic system. This project will complement the broader set of activities undertaken by the "Wajãpi Programme", which started in 1992.
The project focuses on documentation and dissemination of information related to the oral and graphic expressions of the Wajãpi. The participative documentation will be undertaken by the Wajãpi themselves. The project is composed of three main lines of action: (i) undertaking of an ethnological survey, (ii) elaboration of an inventory in the form of an electronic database in close cooperation with the respective custodians, (iii) implementation of dissemination and diffusion activities on Wajãpi oral and graphic expressions" focus on both young Wajãpi and public managers working with indigenous communities in order to increase their knowledge and appreciation of Wajãpi oral and graphic expressions and the need to safeguard the context in which they are practiced.

Aim: Effective early and persistent antipsychotic treatment in recently diagnosed schizophrenia may positively impact long-term outcomes. Paliperidone extended-release (ER) was assessed in this population.
Methods: Post hoc analysis of pooled data from three 6-week, double-blind (DB), placebo-controlled, and three 1-year open-label (OL) studies of paliperidone ER in schizophrenia patients. Data stratified by time since diagnosis (≤3 vs. >3 years).
Results: At DB (n = 1193) and OL baselines (n = 744), 259 (21.9%) and 188 (25.3%) patients were diagnosed ≤3 years. At DB end point, both populations improved with paliperidone ER versus placebo on Positive and Negative Syndrome Scale (PANSS) total, Clinical Global Impressions–Severity and Personal and Social Performance (PSP) scale scores (all P < 0.05). At OL end point, there were significant improvements from DB baseline in both populations on these scales (P < 0.0001), with greater improvement in the ≤3-year population on PANSS total (P < 0.001) and PSP (P < 0.001) scores. During DB treatment, only the ≤3-year population reported adverse events (AEs) in ≥5% (placebo-adjusted rate) of subjects receiving paliperidone ER: akathisia, extrapyramidal disorder not otherwise specified and somnolence. During OL treatment, akathisia and somnolence occurred more frequently (≥5%) in the ≤3- versus >3-year population. OL study completion rates were 51.1% in ≤3-year, and 48.2% in >3-year subjects.
Conclusions: Paliperidone ER significantly improved symptoms and functioning in schizophrenia patients, regardless of time since diagnosis. Recently diagnosed patients who continued treatment exhibited greater symptom reduction and functional benefit over the long term. Results also suggest that these patients may be more susceptible to certain AEs.

Dr. Mine Çetinkaya-Rundel's Statistics 101 course, "Data Analysis and Statistical Inference," began at Duke, spread throughout the world via Coursera (a MOOC provider) and is now finding more ways to reach students at Duke and beyond.
Dr. Çetinkaya-Rundel taught "Data Analysis and Statistical Inference" to Duke undergraduates for several years before developing her teaching materials into an online Coursera course. The standards for the online course, massive audience and deadlines motivated her to create and complete comprehensive learning objectives, polished videos and assessments that were greatly appreciated by students across the world. Now, the materials from the MOOC have come back to campus, where they are having multiple impacts.
The learning materials
The materials developed for the Coursera course include:
- A complete set of learning objectives for each course unit, mapped to readings and "test yourself" questions.
- Lecture videos with downloadable slides and questions to check student understanding throughout the videos.
- Suggested exercises for each unit.
- Links to an online textbook and extensive supplementary resources including videos, tutorials, blogs, and web tools.
Campus Impact: Face-to-face, for-credit courses at Duke
In Fall 2014 and Spring 2015, the two sections of Duke's on-campus "Data Analysis and Statistical Inference" course each enrolled over 100 students. One section was taught by Dr. Çetinkaya-Rundel and the other by Dr. Jesse Windle. Each instructor assigned materials in the Coursera course to help students prepare for their face-toface course.
Dr. Çetinkaya-Rundel assigned the online course material to her students to help them learn basic content so they could apply it during her flipped class. Students are given the learning objectives and can use the text or video to meet these objectives. Explicit learning objectives help students focus on what they need to learn, so they don't get lost in the videos. In addition, there are questions both within the videos and in the learning objectives so that students can test their own comprehension before they come to class.
She found that her students reacted more favorably to preparing for her flipped class using videos than in previous years when she flipped her course using only the text. The content available for her students in Coursera has allowed her to spend more time helping her students apply the content in class. She thinks that delivering the course content online has increased student engagement during class as they work on applying the materials together, and students are spending more time studying outside of class.
Some comments from her students:
This class has been extremely helpful and is an excellent example of how a flipped classroom should work. I enjoy the balance of in-class lecture material and applications. The videos outside of class also really address how I learn and have reinforced the material immensely.
Professor Cetinkaya-Rundel does an amazing job teaching the class. Clickers are a unique way to engage students and to make lectures interesting. The videos, though at times a bit repetitive, are thorough and very helpful. The professor's willingness to gather new data sets and incorporate real-world events into lectures is much appreciated– the associations help make the material much more interesting. I was very worried about getting through this class, but I literally do not think the subject could be taught any better than Professor Cetinkaya-Rundel teaches it.
I just like the idea of the group and the videos because I feel like it helped a lot, especially in explaining difficult concepts. I also like the idea of using the clicker and doing the application question in class because I think it's a better way for me to learn about the information and retain it in my head by putting it into practice.
She noted that it is very time consuming to make good videos, and credited her work with Coursera with motivating her to complete high quality videos.
In Dr. Windle's Fall 2014 Statistics 101 course, materials from the Coursera course supplemented his lectures. He complemented the video examples with examples of his own, to help students apply the course content to different data sets and case studies. He also used clickers in class to check on student comprehension. He is grateful to be able to share the videos with his students to help them learn Statistics.
In his Spring 2015 course, he used the materials to incorporate more active learning in his face to face class. This spring, he has placed more emphasis on in-class exercises and group work to align his course more closely with Dr. Çetinkaya-Rundel's. He agrees that flipping the class leads to a more engaged audience but warns that it also requires a lot of work, noting that the course he is teaching this semester would be infeasible without the help of Dr. Çetinkaya-Rundel and her materials.
Campus Impact: Duke for-credit, summer online course
Dr. Çetinkaya-Rundel uses her Coursera material to teach a hybrid synchronous online course during the summer for Duke students. Students prepare for their online meetings using the Coursera materials, then apply the concepts when they talk with each other during their online meetings.
Campus Impact: Interdisciplinary research project
Dr. Çetinkaya-Rundel has teamed up with Dr. Dorian Canelas and several Duke students on a Bass Connections Project, a new university-wide initiative that links faculty and students to respond to complex challenges through problem-focused educational pathways and project teams. Their team "Coursera and the Future of MOOCs" investigates alternative means of conveying information and probes the future of online education through mixed-methods research, examining characteristics and behavior of the participants in the Coursera course.
Campus Impact: Duke Continuing Studies online course
Duke Continuing Studies is using the MOOC materials to offer an online course, "Data, Statistical Inference, and Modeling" for professionals who need to understand and analyze data. The course is available as either a full 10-week course supplemented by a private learning community or as several independent, short modules. Successful students can earn a noncredit Certificate of Completion from Duke University Continuing Studies with Continuing Education Units (CEUs). This continuing studies course also contributes to graduate education, as the student teaching assistant is a Bass Online Apprentice fellow developing skills for online teaching.
Bonus Impact: Courses across the world
Dr. Çetinkaya-Rundel has received many inquiries about using her course material to supplement other courses, from individuals in organizations ranging from a Russian law school to Dell employee training as well as faculty at various high schools and higher education institutions.
The impact of this Massive Open Online Course continues to ripple both within and outside of Duke! The next offering of Coursera's "Data Analysis and Statistical Inference" starts in March. Join the fun!

City experienced substantial decrease in Sunshine in the month of July. As per the Met department of India, on an average there was only one hour of Sunshine in July.
There is also reduction in solar radiation. Most of the times, sky was covered with the clouds because of pollution in the air. For those who wanted to take Vitamin D from the sunshine had to wait for the sun rays. Some days in the month were completely without sunshine, some days were having some amount of sunshine but it was lowest in last 18 years as per the Met Department. According to the Met department, cloud cover and sun's altitude are the factors affecting the solar radiation. No or low sunshine also affects the health of the people as it brings unwanted diseases.
Now rain has taken a back seat since some days, so let's just hope for some bright and sunny days ahead.

Reversible public key scheme
For a public key encryption scheme with message space $M$, cipher space $C$, and key-pair $(d, e)$:
If
 1. $M=C$ and
 2. $D_d\left(E_e\left(m\right)\right) = E_e\left(D_d\left(m\right)\right) = m$ for all $m \in M$
Then we have a reversible PK scheme. (the notes seem to imply that the second property follows from the first; I am unsure)
We can use reversible PK schemes for digital signatures by reversing the encryption and decryption processes. In the case of RSA this means we encrypt a message we send with our private key and the recipient decrypts it with our public key.

This new Springer book Digitisation and Precarisation : Redefining Work and Redefining Society (edited by Vyacheslav Bobkov and Peter Herrmann) explores new territory in the profound transformations under way with digitisation. In effect, the effects of digitisation on work and society is unchartered territory, only imagined in the science-fiction genre. So this book makes an important contribution in understanding the way that digitisation is breaking down the old social and workforce norms creating a much more precarised, insecure society.
I have a chapter in this book with the following abstract:
The chapter sets out to explore how digitalisation and its effects on the Australian labour market is a force, as in other countries in further advancing employment polarisation and economic inequality. The analysis accords with a core-periphery model of the labour market, but one that is not especially geographic in orientation as most of Australia's population lives in large urban conurbations.

Blue ammonia
This section relates to the relevant consideration for the early adaption of Blue ammonia as an alternative fuel.
Feedstock availability
Fuel production
Fuel storage, logistics & bunkering
Onboard energy storage & fuel conversion
Onboard safety & operations
Vessel emissions
Regulation & certification
Feedstock availability
Blue ammonia
Blue ammonia
Natural gas is the primary feedstock for blue ammonia, and it is produced large scale in almost all regions of the world. The production of natural gas includes risk of upstream emissions including fugitive methane emissions, and these must all be mitigated for blue ammonia to play a role in decarbonizing the maritime industry. Best practice must be established and enforced, and measurement is essential for credible certification.
Fuel production
Blue ammonia
Blue ammonia
Ammonia synthesis is a mature technology using fossil feedstock (natural gas) but to make it carbon neutral the CO2 from the fossil feedstock needs to be captured and stored as part of the production process. A relatively low-cost of CO2 capture may be achieved due to the high concentration (>90%) of CO2 from methane-based ammonia synthesis. Currently, a solution for permanent CO2 storage is not available at scale making the maturation of a global CO2 storage infrastructure a key enabler for the ammonia fuel pathway.
Production of ammonia would need significant scaling as well, and new large-capacity ammonia plants will need to be constructed at record pace if blue ammonia is to have a significant role in decarbonizing shipping.
Fuel storage, logistics & bunkering
Blue ammonia
Blue ammonia
Ammonia is transported globally as a commodity (~20 million ton/year), but port infrastructure such as terminals and bunkering facilities must be significantly expanded to handle potentially hundreds of millions of shipping tons per year. The new technologies and the new requirements create a need for standards around hardware, bunkering and safety procedures.
Onboard energy storage & fuel conversion
Blue ammonia
Blue ammonia
The development of tank storage solutions for larger ammonia volumes, engine, and fuel cell technologies are ongoing. Dual-fuel ammonia engines are being developed but are not finally proven or commercially available yet. It also means that the required post-combustion emission reduction technologies are currently unknown. Solid Oxide Fuel Cells (SOFC) may run on ammonia directly, but SOFCs are significantly less mature and cannot be considered an ammonia-enabler for first movers. Boilers using ammonia as a fuel are under development but not yet commercially available.
Onboard safety & operations
Blue ammonia
Blue ammonia
Ammonia is highly toxic which makes risk assessments and impact on vessel design and cost key areas of investigation.
Onboard safety and operations are crucial for safe operation of ammonia fueled vessels. Currently, LPG carriers handle the safety management of ammonia as a cargo, but a vessel fueled by ammonia will introduce different risk including crew exposure from ammonia leakages or emissions. Risk management incl. quantitative risk assessments and human factor are required to enable detailed design and requirement specification for materials, components, location of systems like storage tanks, fuel gas supply system, and safety management systems.
Vessel emissions
Blue ammonia
Blue ammonia
Combustion of ammonia does not produce CO2 emissions as no carbon is contained in the fuel – except from the quantity of needed pilot fuel if it is carbon-based. Knowledge of, and experience, with emissions from ammonia internal combustion engines is limited. However, the potential exists for emissions of both N2O (a potent GHG combustion byproduct) and NH3 slip (highly toxic). Until fully developed and validated ammonia engines are available, the requirements for emission reduction technologies onboard are unclear. Based on potential emission scenarios, there will be a need for a selective catalytic reduction (SCR) system to remove NOx, potentially an N2O catalyst, as well as an additional catalyst or technology to remove ammonia slip. Based on the uncertainty of actual emissions from the engines under development, there are currently major challenges that need to be overcome before this fuel pathway can be matured.
Regulation & certification
Blue ammonia
Blue ammonia
On the regulatory side, some key outstanding concerns are present for using ammonia as a fuel. There is no ammonia fuel standard (on e.g. purity) which is needed to allow the use of ammonia. There is also no well-to-wake greenhouse gas quantification for ammonia developed in appropriate regulatory bodies such as the International Maritime Organization (IMO) or European Union (EU). Detailed prescriptive rules for ammonia as a fuel are not incorporated into the IGF code, requiring an alternative design approved by the Flag State for current ammonia-fueled vessel design projects. Classification societies have released guidelines for ammonia-fueled vessels; however, they are not consistent or unified in their approaches or requirements
Life cycle assessment policy needs to be developed. Regulating the climate impact of fuel use from a life cycle perspective offers the industry the opportunity to establish sustainable fuel production and consumption patterns. By regulating the upstream (well-to-tank) climate impact, fuel users can select fuels with solid sustainability credentials. Regulation from a life cycle perspective also reduces the risk of burden shift of climate impact from the downstream (tank-to-wake) part of the value chain to the upstream. This is an important consideration for alternative marine fuels whereby much of the climate impact resides in well-to-tank activities.

An integral representation of the displacement for problems of transient propagation of horizontally polarized shear waves is employed to investigate the diffraction of a plane wave by a crack of finite length. The stress intensity factors at small times are derived for an incident wave of arbitrary shape. For a step-stress wave the maximum stress intensity factors are shown to exceed the factors of the corresponding static problem by a factor 4 π. Brittle fracture is subsequently investigated by employing a balance of rate of energy. It is shown that for a step-stress wave the critical stress for brittle fracture is reduced by a factor π 4√2 as compared to the critical stress of the corresponding static problem. Ductile fracture is studied by assuming that yielding is restricted to a narrow band in the vicinity of the crack tips. The propagation velocity of the zone of yielding is computed and the location of the point of rupture is determined.

Swimming has many benefits as a simple, but effective physical exercise. It helps to prevent excessive weight gain without affecting the weight of the newborn and reduces joint pressure and the appearance of edema. In addition, swimming during pregnancy can help relieve stress and improve sleep.
Most pools use chlorine to kill bacteria that can be dangerous to humans. Therefore, from the point of view of infection, swimming in a chlorinated pool is certainly safer than swimming in open water. However, when chlorine is added to water, it reacts with organic substances in the water (such as skin cells and body care products) to form various harmful by-products, such as trihalomethanes (a group of four chemical compounds, including chloroform).
For this reason, some studies suggest that swimming in pools during pregnancy may affect the baby. However, these studies also acknowledge that further research is needed over longer time frames to conclude if there is a significant risk. Therefore, experts still encourage swimming as a beneficial physical activity to undertake while pregnant.
