't know any Audacity function to quantify the total or average amplitude/energy/power of the resulting waveform.
Here is a BASIC program that produces such summary numbers, and stores them in a results file, based on the simpler version I wrote a couple days ago. The main thing I've learned is that this measure is almost identical for my data sets -- the peak correlation totals vary by only about one part in 15,000. It looks like turning on jitter correction in fre:ac helped, and that reading at 16x was optimum -- but the differences are so small that they probably don't mean much. The BASIC program takes a few minutes to process each 50 second .wav file. So even though there are many ways it could be much more efficient and run much faster, there is no need to bother yet.

Audio CD ROT, Red Book CD-DA data recovery, Disc Rot

Unfortunately, most modern laptops lack line-input ports (only have headphone out and mic in). I have bought an Xitel INport USB adapter, and do expect to try re-digitizing at some point. But as an amateur perfectionist, I'd much rather work on trying to recover an exact copy of the audio CD digital data then have to struggle with the details of trying to make an impossible "perfect" new digital copy of the aged analog recording.
The CDRs have deteriorated and may have unrecoverable errors. The tapes may not have deteriorated at all. You have the hardware to digitize, apparently. I think it's worth spending a few minutes testing the tapes.

isobuster can be downloaded and installed and used free for some recovery. For other conditions it will test and tell you if it sees anything to recover -- once you pay for the program.
If you decide to try the cassettes, first check that the pressure pads are present and intact. Then rewind the cassettes to get the tension more even so the playback speed will be more stable.

Have you tried out ExactAudioCopy yet ? _URL_ This is also free / shareware.
This software keeps re-reading the bad sectors until eventually it gets a correct checksum and then moves on.
Quote:
In secure mode this program either reads every audio sector at least twice or rely on extended error information that some drives are able to return with the audio data. That is one reason why the program is slower than other rippers. But by using this technique non-identical sectors are detected. If an error occurs (read or sync error), the program keeps on reading this sector, until eight of 16 retries are identical, but at maximum one, three or five times (according to the selected error recovery quality) these 16 retries are read. So, in the worst case, bad sectors are read up to 82 times! But this effort will help the program to obtain the best result by comparing all of the retries.
Also, you may want to try an older (slower CD drive) which may also help to recover the data.

Yes, EAC is what I usually use, and the first thing I tried -- but I could not find any way to turn the error-checking down enough to get it to make any process with these rotted CDs. And yes, I also was hoping that older slower CD drives might help, but nothing in my pile of old drives worked at all...

BASIC PROGRAM UTILITY TOOL
TO INSPECT BLOCKS OF DIFFERENCES
IN MULTIPLE SETS OF ALMOST IDENTICAL .WAV FILES
The following BASIC program analyzes a set of nearly identical .wav files, finds block-chunks areas of difference and displays a grid of numbers for interactive inspection. It analyzes each such block and collects summary statistics into a results file.
I am experimenting with a set of 7 copies of a track from a set of audio CDs that have become unplayable (rotted). I was only able to get data from 2 discs: 5 copies from one disc and 2 copies from another.
Just eyeballing the grid of numbers, with the differing values highlighted, the first impression is that this data recovery project looks hopeful. In many cases the errors are isolated and should be easy to weed out. The blocks of errors are mostly not long runs. Usually there are not more than two values appearing for a given sample.
This 50 second stereo track is somewhat over 2,000,000 L-R 16-bit sample pairs. Running the program on all 7 copies produced this (highly edited) output:
E1.wav E2.wav E3.wav E4.wav E5.wav N1.wav N2.wav

Each set of samples is analyzed to count how many different values appear, and count the total of "minority" values (how many values are different from the one that is most common). Each block has a max result for those two measures; these results are tallied for all the blocks.

Update (10/27/2023): The seventh Philadelphia school in 2023 closed due to asbestos. According to the Philadelphia Inquirer, Southwark Elementary School closed in October. Most students would attend South Philly High School. It's the first school closure in Philadelphia of the 2023-2024 school year.
Update (05/01/2023): The sixth Philadelphia school in 2023 was closed due to finding asbestos. According to CBS News, Universal Vare Charter School is temporarily closed asbestos was detected during a routine check.
Update (04/25/2023): Another school in Philadelphia closed due to asbestos. According to NBC10 Philadelphia, C.W. Henry School in the Mount Airy neighborhood closed due to finds of the cancerous substance. This makes five Philadelphia schools to close because of asbestos just in 2023.
There's another chapter to the ongoing asbestos crisis in Philadelphia public school buildings.
According to the ABC affiliate in Philadelphia and other media outlets, two more Philadelphia schools closed due to discoveries of dangerous asbestos. This makes multiple reports in the last few weeks of Philadelphia schools dealing with asbestos sightings.
According to the reports, Frankford High School and Mitchell Elementary School closed down the second week of April, after Spring Break ended. Virtual learning began Tuesday, April 11. There are approximately 900 students at Frankford High and 350 students at Mitchell Elementary.
According to the Philadelphia Inquirer, the issue occurred due to inaccurate record-keeping of asbestos-containing plaster. The records inaccurately labeled the plaster as "non-asbestos containing" and safe for decades.
Reports state Frankford High School may reopen within a week after closing, but Mitchell Elementary School should remain closed for the rest of the school year. While virtual learning is a temporary solution for the students, the plan reportedly is to find an in-person setting for Mitchell Elementary students for the remainder of the school year.
What Is Asbestos?
Asbestos is a dangerous mineral that can cause mesothelioma cancer, lung cancer and other deadly diseases. It is a fire-resistant and durable substance capable of preventing fire damage in buildings. However, as years pass with no renovation or repairs, asbestos can decay and fragment, which releases sharp fibers that can cause cancer if inhaled or ingested.
During the 20th century, many buildings were constructed with asbestos inside of the walls, in roof tiles and more. School buildings were part of the group, and many old school buildings that haven't been renovated in decades still contain decaying asbestos.
Asbestos Concerns Among Philadelphia Schools in 2023
These are the third and fourth Philadelphia buildings to close due to asbestos just in 2023. Building 21 High School closed down in March as students were relocated to Strawberry Mansion High School. The next week, Mastery Charter Simon Gratz High School was shut down. They reopened soon after.
According to The Philadelphia Inquirer, approximately 400 students from Building 21 High School have occupied one floor of Strawberry Mansion High School since the school closed.
As of October 2023, there have been seven Philadelphia schools to close since March 2023:
- Building 21
- Frankford High
- C.W. Henry Elementary
- Mastery Simon Gratz High
- Mitchell Elementary
- Southwark Elementary
- Universal Vare charter school
There have been other Philadelphia schools dealing with asbestos prior to 2023. The crisis began in 2019, when Benjamin Franklin High School and Science Leadership Academy shut down. Five more schools shut down in 2019 and four schools shut down in 2020, prior to the COVID-19 pandemic.
If not for the pandemic shutting down in-person learning, there might have been more asbestos sightings in other schools a lot sooner than in 2023.

This paper presents a new strategy for obstacle avoidance in mobile robots leader-follower formation. The key feature of the algorithm is that the system is robust against absolute acceleration of both leader and obstacle. On the other hand the angular velocity constraint of leader and obstacle is eliminated in the proposed leader-obstacle formation. The formation controller is composed of a feedback linearization part and a sliding mode compensator. Similar structure is used for both leader-follower and leader-obstacle formation. The proposed controller generates the commanded acceleration for the follower robot and makes the formation control system robust against the unmeasured acceleration of the leader robot and obstacle. Simulation results are presented to show the validity of the proposed methodology.


text: This 2013 Article IV Consultation highlights that economic output in Aruba remains 12 percent below its pre-crisis level, with recovery slower than others in the Caribbean region. The non-oil current account (CA) balance, which mostly reflects developments in the tourism sector, has improved since mid-2000 reaching a balanced position in 2012. The overall CA balance, however, after being in surplus for years, showed volatilities in recent years reflecting oil-sector developments. In 2012, it recorded a surplus of 5 percent of GDP. In 2013, real output is projected to grow by 11/4 percent. Robust tourism growth and some pickup in consumption from projected deflation will support the subdued near-term recovery.

Microsoft Xbox 360 Setup Instructions
ResNet recommends connecting your console using a wired internet connection through a router. The wired connection is more reliable and can be up to 20X faster than the wireless connection. Using a router also allows you to connect multiple devices to the wired port at the same time, without having to re-register. For more information on how to setup a router with the Georgia Tech network, see our router setup page.
Wired Configuration for Microsoft Xbox 360
If you will be connecting more than one device to the wired port in your room, you will need to use a router. If you need help setting up your router, check out our router setup tutorial. Once your router is set up, simply connect your Xbox directly to one of the ports on the router and you should be good to go.
If you want to connect your Xbox 360 directly to the wired port in your room, you can do so without a router.
 1. Connect your Xbox 360 to the port in your room with an ethernet cable.
 2. Turn on your Xbox and go to the dashboard.
 3. Navigate to System Settings, then to Network Settings.
 4. Select Configure Network.
 5. Select Wired Connection with an automatic configuration and test the connection. It should fail at this point, but this step lets our switch see your Xbox.
 6. Return to the Configure Network menu.
 7. Scroll right to the Additional Settings tab.
 8. Scroll down and select the box containing Advanced Settings, Host Name, and Alternate Mac Address.
 9. At the bottom of the screen, just above the Done button, you should see Wired MAC Address, followed by a series of 12 letters and numbers. Write this series down.
 10. Using a computer or any device with a web browser, navigate to Sign in with your GT account.
 11. Press Register a Different Device.
 12. Read the information on this page. Then, in the MAC Address box, type in what you wrote down in step 9.
 13. Select whether you live in a Residence Hall or Greek House.
 14. Finally, enter a brief description of the Xbox, like "My Xbox."
 15. If you understand the terms of registration, and accept responsibility for your device, select I Accept Responsibility for This Device.
 16. Turn off your Xbox and wait five minutes before turning it on again.
If you are having problems, you may want to visit Microsoft's support site for router port configuration for more information. If you are still having problems, please contact us!
LAWN Configuration for Microsoft Xbox 360
 1. If you have a new Xbox 360, it should have wireless support built-in. If you have an older Xbox 360, you will need to purchase a wireless adapter. For more information, go to Microsoft's Wireless Adapter product page.
 2. Owners of both old and new Xboxes need to write down their console's internal MAC address, which can be found at [System] -> [Network Settings] -> [Edit Settings] -> [Additional Settings] -> [Advanced Settings], at the bottom of the page, under 'Wired MAC Address.' Do not use the 'Wireless MAC address' - this will not work.
 3. Navigate back to [Edit Settings], go to [Wireless Mode], and select 'GTother' from the list of internet connections.
 4. Enter the security key, and select the WPA option. If you do not have the WPA key, you may get from the LAWN SSID and WPA key webpage.
 5. Run the connection test. It should fail, but that's okay.
 6. On your personal computer, navigate to the LAWN Device Login page. Fill in your GT account, password, and the MAC address that you wrote down earlier, and check the 'disable ISS' check box (Allows you to play online). Note that you will need to log in by this method every time you want to log on to the internet through wireless.
You should now be able to connect to the internet and Xbox Live.

Idea
An exact sequence may be defined in a semi-abelian category, and more generally in a homological category. It is a sequential diagram in which the cokernel of each morphism is equal to the kernel of the next morphism.
Definition
Definition in additive categories
Let 𝒜\mathcal{A} be an additive category (often assumed to be an abelian category, for instance 𝒜=R\mathcal{A} = RMod for RR some ring).
Definition
An exact sequence in 𝒜\mathcal{A} is a chain complex C C_\bullet in 𝒜\mathcal{A} with vanishing chain homology in each degree:
n.H n(C)=0. \forall n \in \mathbb{N} . H_n(C) = 0 \,.
Definition
A short exact sequence is an exact sequence, def. of the form
00ABC00. \cdots \to 0 \to 0 \to A \to B \to C \to 0 \to 0 \to \cdots \,.
One usually writes this just "0ABC00 \to A \to B \to C \to 0" or even just "ABCA \to B \to C".
Remark
A general exact sequence is sometimes called a long exact sequence, to distinguish from the special case of a short exact sequence.
Proposition
Explicitly, a sequence of morphisms
0AiBpC0 0 \to A \stackrel{i}\to B \stackrel{p}\to C \to 0
is short exact, def. , precisely if
 1. ii is a monomorphism,
 2. pp is an epimorphism,
 3. and the image of ii equals the kernel of pp (equivalently, the coimage of pp equals the cokernel of ii).
Proof
The third condition is the definition of exactness at BB. So we need to show that the first two conditions are equivalent to exactness at AA and at CC.
This is easy to see by looking at elements when 𝒜R\mathcal{A} \simeq RMod, for some ring RR (and the general case can be reduced to this one using one of the embedding theorems):
The sequence being exact at
0AB 0 \to A \to B
means, since the image of 0A0 \to A is just the element 0A0 \in A, that the kernel of ABA \to B consists of just this element. But since ABA \to B is a group homomorphism, this means equivalently that ABA \to B is an injection.
Dually, the sequence being exact at
BC0 B \to C \to 0
means, since the kernel of C0C \to 0 is all of CC, that also the image of BCB \to C is all of CC, hence equivalently that BCB \to C is a surjection.
Definition
A split exact sequence is a short exact sequence as above in which ii is a split monomorphism, or (equivalently) in which pp is a split epimorphism.
In this case, BB may be decomposed as the biproduct ACA \oplus C (with ii and pp the usual biproduct inclusion and projection); this sense in which BB is 'split' into AA and CC is the origin of the general terms 'split (mono/epi)morphism'.
Definition in pointed sets
It is also helpful to consider a similar notion in the case of a pointed set.
Definition
In the category Set *Set_* of pointed sets, a sequence
(A,a) f (B,b) g (C,c) \array{ (A, a) & \overset{f}{\to} & (B, b) & \overset{g}{\to} & (C, c) }
is said to be exact at (B,b)(B, b) if imf=g 1(c)im f = g^{-1}(c).
For concrete pointed categories (ie. a category 𝒞\mathcal{C} with a faithful functor F:𝒞Set *F: \mathcal{C} \to Set_*), a sequence is exact if the image under FF is exact.
In the case of (abelian) categories like AbAb and RModR-Mod, the two notions of exactness coincide if we pick the point of each group/module to be 00. Such a general notion is useful in cases such as the long exact sequence of homotopy groups where the homotopy "groups" for small nn are just pointed sets without a group structure.
Properties
Computing terms in an exact sequence
A typical use of a long exact sequence, notably of the homology long exact sequence, is that it allows to determine some of its entries in terms of others.
The characterization of short exact sequences in prop. is one example for this: whenever in a long exact sequence one entry vanishes as in 0C n\cdot \to 0 \to C_n \to \cdot or C n0\cdot \to C_n \to 0 \to \cdots, it follows that the next morphism out of or into the vanishing entry is a monomorphism or epimorphism, respectively.
In particular:
Proposition
If part of an exact sequence looks like
0C n+1 nC n0, \cdots \to 0 \to C_{n+1} \stackrel{\partial_n}{\to} C_n \to 0 \to \cdots \,,
then n\partial_n is an isomorphism and hence
C n+1C n. C_{n+1} \simeq C_n \,.
Exactness and quasi-isomorphisms
Proposition
A chain complex C C_\bullet is exact (is a long exact sequence), precisely if the unique chain map from the initial object, the 0-complex
0C 0 \to C_\bullet
is a quasi-isomorphism.
Short exact sequences and quotients
The following are some basic lemmas that show how given a short exact sequence one obtains new short exact sequences from forming quotients/cokernels (see Wise).
Let 𝒜\mathcal{A} be an abelian category.
Lemma
For
ABC0 A \to B \to C \to 0
an exact sequence in 𝒜\mathcal{A} and for XBX \to B any morphism in 𝒜\mathcal{A}, also
AB/XC/X0 A \to B/X \to C/X \to 0
is a short exact sequence.
Proof
We have an exact sequence of complexes of length 2
0 X id X 0 A B C 0 \array{ 0 &\to& X &\stackrel{id}{\to}& X &\to& 0 \\ \downarrow & & \downarrow & & \downarrow & & \downarrow \\ A &\to& B &\to& C &\to& 0 }
and the exact sequence to be demonstrated is degreewise the cokernel of this sequence. So the statement reduces to the fact that forming cokernels is a right exact functor.
Lemma
For
0ABC 0 \to A \to B \to C
an exact sequence and XAX \to A any morphism, also
0A/XB/XC 0 \to A/X \to B/X \to C
is exact.
Examples
Specific examples
Example
Let 𝒜=\mathcal{A} = \mathbb{Z}Mod \simeq Ab. For nn \in \mathbb{N} with n1n \geq 1 let n\mathbb{Z} \stackrel{\cdot n}{\to} \mathbb{Z} be the linear map/homomorphism of abelian groups which acts by the ordinary multiplication of integers by nn. This is clearly an injection. The cokernel of this morphism is the projection to the quotient group, which is the cyclic group n/n\mathbb{Z}_n \coloneqq \mathbb{Z}/n\mathbb{Z}. Hence we have a short exact sequence
0n n. 0 \to \mathbb{Z} \stackrel{\cdot n}{\to} \mathbb{Z} \to \mathbb{Z}_n \,.
Remark
The connecting homomorphism of the long exact sequence in homology induced from short exact sequences of the form in example is called a Bockstein homomorphism.

500 Request Item Limit when generating requests from JSON Payload
We have found that there is a 500 request item limit when generating requests from JSON payload. We have developed a process to loop through the request items and generate multiple payloads when there are 500+ items. This however does create a few pain points that we have found (below).
- Large dimension import processes are not uncommon, sometimes requiring the generation of 20+ payloads. From a technical perspective this is not an issue, however it does create pain points for application admins when attempting to troubleshoot import issues. Each payload generates its own request file, so when attempting to troubleshoot an issue you need to weed through many request files to see the source data that the import process is loading.

Hyperdawn is the moniker of Salford based experimentalists Michael Cutting and Vitalija Glovackyte. Off the back of their prolific individual projects, ranging from multimedia performances to studio releases, orchestral works to solo live sets, the duo has steadily developed a distinctive voice as Hyperdawn, forging modified keyboards, homemade instruments and reel to reel tape recorders. Their debut album Bleach takes their physical, process-based aesthetic with imperfections of warped tape and faltering hardware and pushes it towards the boundaries of pop music. Hints of verse-chorus structures are now apparent with the use of Vitalija's voice as an essential introduction, giving the duo's rough grained instrumentals a new level of poignancy.
While the reel to reel machines provide the album's characteristic sound, this isn't music for the analogue purist. Digital processes have their place here, countering the warmth of valve amplifiers with glitchy pitch-bending effects, matching un-quantised tape loops with high frame-rate playback. Bleach displays a delicate balance between new and old, skeletal and substantial, rigour and recklessness. The result is a broken pop music borne out of hours of improvisations and experimentation that feels at once completely foreign and entirely familiar. Ambiguous textures and structures are contextualised by Vitalija's confident vocal delivery. Beats are left off-kilter, intonation is approximate, while clicks and pops protrude over decaying instrumentals, suggesting music that is already disintegrating in time.
Michael and Vitalija have taken their live show to venues and festivals across the UK, US, Canada and Europe as well as had their music broadcast on BBC Radio 3 (Late Junction), NTS Radio and Berlin Community Radio amongst others. Bleach will be released on September 2019 via Them There Records and will be made available on vinyl and digital formats. Followed by a headline European tour.

Virginia State Route 244
From Wikipedia, the free encyclopedia
|Maintained by VDOT|
|Length:||8.25 mi (13.28 km)|
|Existed:||1933 – present|
|West end:||SR 236 in Annandale|
|East end:||SR 27 at the Pentagon|
State Route 244, also known as Columbia Pike, is a primary state highway in the U.S. state of Virginia. It is a four-lane road that runs from State Route 236 (Little River Turnpike) in Annandale, Fairfax County east to State Route 27 at the Pentagon in Arlington County.
Columbia Pike dates to 1810 when the U.S. Congress chartered a turnpike Company to build three separate roads through the newly-formed District of Columbia to outlying destinations. One of these roads was to be built through a portion of the District of Columbia that had previously been part of Virginia. This portion was then known as Alexandria County, D.C. (now Arlington County, Virginia). The purpose of this road was to provide access westward from the new Long Bridge that predated the 14th Street Bridge complex to the Little River Turnpike Road, now Virginia State Route 236. The new road was built on a pre-existing cow path as the Washington Graveled Turnpike and was also known as the Washington Road, the Columbian Road, and the Arlington Turnpike.
Columbia Pike was first numbered as State Route 720 in 1930 from U.S. Route 1 near the Long Bridge west for around 1 mile (1.6 km). In the 1933 renumbering, it was renumbered State Route 244 and the numbering was extended first to State Route 7 at Bailey's Crossroads and then, between 1934 and 1937, further west to its current terminus at SR 236 in Annandale. With the construction of the Pentagon Columbia Pike was replaced by the Shirley Highway as the Virginia approach to the Long Bridge/14th Street Bridge. By 1944, SR 244 was truncated at the Pentagon; the piece curving away from the original alignment became a state highway in 1964. Until the 1990s, Columbia Pike accommodated rush hour traffic by reversing the direction of one lane using overhead signals. In October 2010, Virginia transferred responsibility for the eastern portion of Columbia Pike to Arlington County.
Contemporary Columbia Pike
The road is a center for Arlington's immigrant community, with many stores, restaurants, and other businesses representing south Arlington's cultural diversity. Also, a weekly farmer's market is held each Sunday during the warmer months of the year. The Pike is intersected by the Four Mile Run Trail and the Washington & Old Dominion Railroad Trail, multi-use trails for pedestrians and cyclists leading northwest to Glencarlyn Park and southeast to Shirlington, at South Four Mile Run Drive.
In 2002, Arlington County adopted the Columbia Pike Initiative, a revitalization plan for the three-and-a-half mile corridor in Arlington. The plan called for development of a high-capacity transit system. The Columbia Pike Initiative was followed in 2003 by adoption of the Form Based Code, which guides development along Columbia Pike. In 2004, the Columbia Pike Street Space Planning Task Force recommended future transit operate in mixed traffic and that the transitway be located in the curb lanes.
Recent efforts by the Columbia Pike Revitalization Organization include the replacement of older traffic signals with newer and more aesthetic ones, and the addition of brick texture to crosswalks. County officials also teamed up with the Washington Metropolitan Area Transit Authority to increase mass transit service along the corridor. This new program called Pike Ride remodeled bus stops and doubled bus frequency along Columbia Pike. In 2006, the Arlington County and Fairfax County Board of Supervisors approved plans of bringing railed streetcars to Columbia Pike along an either a 5 or 6-mile (9.7 km) stretch from the Pentagon to the Skyline area.

Want to start your day like an American legend? A pancake recipe from civil rights activist Rosa Parks was recently unearthed by Dan Pashman, the host of The Sporkful podcast. And it features a creamy, protein-rich ingredient.
Parks' secret? Peanut butter. Not only does this nutty ingredient provide flavor to the batter, it also adds extra protein to the breakfast staple (there are six grams of protein in each pancake).
Library of Congress/Rosa Parks Papers
The recipe, scribbled on the back of an envelope by Parks, comes from the recently opened Rosa Parks Collection at the Library of Congress. According to The Washington Post, the collection "features previously unseen personal writings, letters, speech notes, financial and medical records, political documents and decades of photographs."
And it's pretty incredible that among Parks' handwritten account of her bus arrest and postcards written by Rev. Martin Luther King Jr., you can also find her handwritten pancake recipe. Because this tells us that apart from being a rebellious badass and lifelong activist who championed black power, Parks also enjoyed eating pancakes just like the rest of us.
Library of Congress curator Adrienne Cannon tells NPR that the "recipe is quintessentially African-American" because of the peanut butter. By 1940, peanut production was second only to cotton in the South.
To make the pancakes just a bit more healthy, try swapping out the all-purpose flour for buckwheat flour. You can also substitute the whole milk with almond milk to make the pancakes dairy-free. And if you're feeling indulgent, top a stack of the cakes with extra melted peanut butter and dark chocolate chips.
Head here for the full recipe: Rosa Parks' Featherlite Pancakes
What Do YOU Think?
Would you put peanut butter in your pancake batter? Are you always searching for the perfect protein-packed breakfast recipes? Would you try Rosa Parks' pancake recipe?

Description: The purpose of this study was to determine the extent to which faith-based preschools promote spiritual development in preschoolers. The participants in the study were faith-based early childhood teachers and administrators from seven states. Early childhood professionals representing 11 Christian faith traditions completed written surveys or online surveys. A total of 201 faith-based educators completed the survey; 20 respondents participated in semi-structured interviews. The concurrent triangulation mixed-method design provided data on 8 program dimensions which support children's spiritual development: prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. I analyzed quantitative data using descriptive and inferential statistics. All items were examined using mean, standard deviation, frequency, and percentages. Qualitative data gathered from semi-structured interviews were coded and analyzed using NVivo8® qualitative analysis software (QSR International, Inc., Cambridge, MA, _URL_). From this data I identified the extent to which faith-based preschool programs support children's spiritual development through the practices of prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. Data analyses revealed statistically significant differences in faith-based teachers' hours of training in children's spiritual development across all program practice dimensions. A key finding of the study was that training in children's spiritual development...

Waco Scottish Rite's Gifts to Camp Success Approach Half Million Mark
October 8, 2009
WACO, TX--Donating $85,000 to Camp Success, Baylor University's summer literacy program, is only the tip of the iceberg for Waco Scottish Rite. Completely funded by Waco Scottish Rite, donations to Camp Success total nearly $500,000 over the past seven years. And the members of Scottish Rite also consistently give their time, energy and heart to the camp because they believe in the impact the program makes on each child involved.
"Camp Success made a big difference in my son's life. They've found out what things are wrong, so that we can help him. It's made him want to do work--want to read. This has given him another chance," commented Robin Reinke, a Camp Success parent.
"It allows a child to be what they can be. Our institutions are full of people who weren't given that opportunity," stated Claude Ervin, chairman of Waco Scottish Rite. "Camp Success helps them become self-sufficient people who are a productive part of the community."
The language and literacy needs in the Waco community can seem insurmountable, but Camp Success is the beginning of a solution. As of Camp Success' recent graduation, 1,074 students have graduated from Camp Success, and 204 graduate students have shared this experience.
"Camp Success changed my life. My reading was dead, but Camp Success brought it back to life!" exclaimed Caleb Jones, a third-grade student in the program.
In 2003, Camp Success began with only 24 children and now serves 80 children with a waiting list of nearly 200. Participants ranging in age from five to 18 are evaluated before camp begins to determine their specific strengths and weaknesses. Speech pathologists then develop a step-by-step plan tailored to each child.
"The impact on the teenagers is powerful," said Dr. Michaela Ritter, the director of Camp Success and assistant chair for Baylor's department of Communication Sciences and Disorders. "When you see that they were failing classes and now they're making Bs and even As and going to college--it's so rewarding."
During the four-week program, each student benefits from 50 hours of tutoring, which is the equivalent to the reading instruction provided in up to 15 weeks in elementary school classrooms. Complete with various weekly themes, a tactic designed to hold the children's interest, Camp Success is a unique program that touches lives in the Waco community.
"We're making a long-term investment in peoples' lives, and the community benefits because they will become productive, involved and self-sufficient citizens. And the school systems benefit immediately because it increases their standards and test scores," Ervin stated.
"It's not just the money. The Scottish Rite people bring doughnuts every morning for the students, they provide T-shirts for all of them and they support us by just taking the time to talk to the kids," Ritter said. "I cannot praise them enough."
Camp Success is a win for everyone: the students, the community, the school systems and even Baylor students. Baylor speech pathology graduate students serve as clinicians working alongside Baylor faculty, to earn practicum hours toward their degree programs.
"The graduate students see fast progress, and confidence soars--for both the graduate student and the child. Typically speech pathologists are with a client two times a week for one hour each time, so when the students get this intensity, they see the progress and then take the same strategies into the workforce," Ritter said.
"I've never been given the opportunity to mentor someone and actually see the results until now," explained Adam Torres, a Baylor graduate student who is a clinician for Camp Success. "It's been amazing to see them utilizing the strategies we've taught them effectively."
Scottish Rite's recent donation equipped the camp with books, supplies and faculty salaries, empowering the camp to keep touching lives. Their consistent partnership enables Camp Success, now in its seventh year, to provide free language and literacy therapy--therapy that would cost parents $7,000 to $10,000 if paid out of pocket.
"The breadth and depth of the program is immeasurable," Ervin said. "It can be whatever we want to make it--all we need is more people who have enough interest to help it forward."
Jacob Suchecki, one of the many students impacted by Camp Success, announced his gratitude, "Thank you Scottish Rite for giving us all the money so that we can get the stuff we need for success."

Fuzzy sets on 2D spaces for fineness representation
MetadatosAfficher la notice complète
Fuzzy setsFeature extractionImage analysisTexture modeling Human perception
The analysis of the perceptual properties of texture plays a fundamental role in tasks like semantic description of images, content-based image retrieval using linguistic queries, or expert systems design based on low level visual features. In this paper, we propose a methodology to model texture properties by means of fuzzy sets defined on bidimensional spaces. In particular, we have focused our study on the fineness property that is considered as the most important feature for human visual interpretation. In our approach, pairwise combinations of fineness measures are used as a reference set, which allows to improve the ability to capture the presence of this property. To obtain the membership functions, we propose to learn the relationship between the computational values given by the measures and the human perception of fineness. The performance of each fuzzy set is analyzed and tested with the human assessments, allowing us to evaluate the goodness of each model and to identify the most suitable combination of measures for representing the fineness presence.

A Case Study of Groundwater Quality in Industrial Area of Srinagar, J&K
Abstract - Main source of drinking and daily use for domestic purposes is the groundwater, for both urban and rural areas. Surface and ground water are frequently polluted as a result of industrial and agricultural operations. Study of groundwater in Srinagar capital has been conducted to determine its appropriateness for home use. To know about the present quality of groundwater in industrial and non-industrial areas of Srinagar district of Jammu & Kashmir, the present study was conducted. Samples were collected from each site (two from each site) and various parameters including pH, total hardness, electrical conductivity, total dissolved solids, total alkalinity, chlorides, calcium, magnesium, BOD and turbidity were analysed and variation of groundwater quality is analysed by the related parameter. Water samples were collected from industrial and non-industrial areas of Srinagar through different sources which include hand-pumps, tube-wells and springs. The samples were collected and shifted to cleaned plastic bottles; each sample was then namedwith marker and brought to the laboratory for testing. Standard methods are used in the research for determining various parameters and results obtained were compared with the Bureau of Indian Standards (BIS) guideline values and Water Quality Index (WQI) was calculated for each stations. The WQI in industrial area was found with the least value of 40.97 and highest WQI value was observed as 63.1. The computed WQI shows that water samples lie in 'good to 'poor' category indicating that groundwater is not fit for direct consumption and treatment is required in the area. Similarly, the WQI in non-industrial area was found with the minimum value of 34.08 and the maximum value of 48.16. The computed WQI shows that water samples fall in 'good' category and is thus fit for domestic purposes.

Almost Jigless Bicycle Frame Building

I grew up on Legos and the Whole Earth Catalog. These days: bike builder, map maker, trail sleuth.
Intro: Almost Jigless Bicycle Frame Building
This Instructable shows some basic, simple tooling to help build a bicycle frame. It's aimed for someone building their first few frames who is unable to invest the time or money into a full framebuilding jig.
Step 1: Introduction
Every person who decides to build their first frame is faced with the question: "What do I use for a jig?"
Commercial jigs start at about $1600. For the beginner this could be a huge investment - the equivalent of many bicycles worth of tubing.
There is also the option of building a jig out of 8020, such as described in my Instructable here. However, the cost on this is also not trivial, probably $350-$500, and it does require some machining work that is outside of the common garage tools.
If you ask around on the internet, many people will tell you that you don't really even need a jig, you just need a flat surface and some sort of tooling to hold your tubes at a fixed height above the surface. This is quite true, but for some people using an old pool table or maybe a surface plate is not exactly convenient, due to the size and weight.
This design and method is what I developed over building my first 5 frames. It's compact and cheap, and works by giving you a system of 3 small orthogonal flat surfaces to work with, and several means of holding tubes at the right position while you tack them.
However, since this jig is compact, you can only work on one joint at a time. This is the standard way for beginners to build, as described in the Paterek Manual. If you haven't heard of it yet, it's essentially the beginning framebuilder's bible. You can purchase it from Paterek or Henry James. The main disadvantage on this is that you never see the complete picture of the frame until you tack in the last tube. You can't set it up and then have a sanity check where you can see if it all makes sense.
I no longer have this jig, having moved on to my 8020 design, so I had to reproduce everything in SketchUp. For the sake of speed, I didn't model everything exactly to scale or try to make everything look perfect. But it should get the idea across.
If this Instructable helps you out, you can always show your appreciation through my Amazon Wish List.
Speaking of books, you might also want to check out Atomic Zombie's Bicycle Builder's Bonanza. While it doesn't cover classical framebuilding like the Paterek Manual, it does have lots of good ideas for "low road" building.
The materials are simple steel structural shapes:
1" x 1/4" bar, about 6", though get a foot since you'll eventually use it.
4"x 3" angle iron, give or take an inch in either leg, about 7-8' total
1"x 1" angle iron, another foot or so
Old rear hub axle(s) or similarly sized threaded rod and nuts
Some bolts, about M5 x 40 or whatever you have taps for.
A couple of Welder's magnets, available from Harbor Freight for cheap.
For tools you'll need a hacksaw, a drill and bits, and a tap to match your bolts.
Step 2: Base
The base is just three pieces of the angle iron welded together. You have a main piece about 4' long that serves as the flat surface you will do most of your work on.
A smaller piece, about 2' long, is welded underneath it to form a sort of Z-profile. This piece is used to clamp the jig to the front of your workbench. If you want to bolt it to your workbench you can drill some mounting holes in it.
The final smallest piece is about 8" long as is welded perpendicular to the top piece. This gives three surfaces that are all orthogonal to each other. Measure with a machinist's square to make sure the angle is 90 degrees before you weld it!
Note: when I say "weld", this includes other joining techniques such as brazing, or even drilling and bolting/riveting.
Also shown in the picture are the dummy axle and a tube lift, which are described in the next two steps.
Step 3: The Dummy Axle
The dummy axle is just a piece of the steel bar with a hole drilled in it to accept and axle. The axle is held in place by nuts on each side (not shown). You can use axles, cones, and locknuts (both quick-release and solid) scavenged from old hubs, or use threaded rod and nuts.
Since the inside of the bar is on the same vertical plane as where the right end of the bottom bracket contacts the upright reference piece, you can use it as the reference for you axle locknut locations.
Looking at the dummy axle from the rear, your left locknut will be 34mm plus half of your hub width. The right side will be half of you hub width minus 34mm. This all assumes you are using a 68mm shell.
In use, the piece is just clamped to the angle iron with a C-clamp.
Since this is so simple, you might as well make a new one for each axle size.
Step 4: Tube Lifts
These simple tube lifts are one possible way of holding a tube the required distance from the surface plane. It is just made by welding the 1x1 angle iron back-to-back with another piece. They only need to be an inch or two long.
NOTE: Since this references the OD of the tube, you will need to make them for each size of tubing! The height of the lift will need to 34mm minus half of the tube diameter (assuming you're using a 68mm bottom bracket).
Clamp them together at the right height and give them a tack weld on each side. After in cools double-check that the height came out right. If one side is off, knock off the tack and bend it to the right height and tack it again. Since this doesn't need to hold any significant weight, the tacks are all you need to hold it together.
After you finish each piece, don't forget to label them with the tubing size you built it for!
However, this isn't the only way to align the tubes, as you'll see in the next few steps.
Step 5: Joining the Bottom Bracket and Seat Tube
Usually the first step is to join the bottom bracket to the seat tube. I won't go into all the details such as mitering and drilling vent holes. Get the Paterek Manual if you need to find out more about that part of fabrication.
With a big C-clamp and some flat bar stock (not shown), clamp the bottom bracket to the jig table. Then using the appropriate sized tube lifts (also clamped to the jig as shown), line up the seat tube against the bottom bracket over the vent hole. Welder's magnets will hold it place for you to tack the tube. You also might be able to use those big spring clamps (the ones that look like big metal clothespins) to hold the tubes against the lifts.
Of course, before you tack the tube, double-check that the seat tube is parallel to both the jig face and to a straightedge lined up against the face of the bottom bracket.
After you tack it, check for parallelism again.
Step 6: The Alternate Method
The other option for this step is much simpler.
Drill and tap two holes in the jig base and thread in bolts from the bottom. When used with a couple of welder's magnet, this will hold the tube in place for tacking.
In this case, just fine-tune the height of your bolts to get the tube parallel to the jig base and the bottom bracket face.
As in the previous step, the clamp on the bottom bracket is not shown.
Step 7: Another Way to Hold a Tube
Here's another way to hold a tube at a given height that I've used.
Clamp a piece of angle iron to your base, and then clamp the tube to the angle iron upright using a metal spring clamp. You could also use a small C-clamp, if you file the flat end of the C-shaped part of the clamp to have a round profile to fit inside the tube without denting it.
Step 8: Tacking the Head Tube and Down Tube
Again skipping the mitering steps, the head tube and down tube are tacked together as shown in the Paterek manual. If you're building it lugless, this is done free-form by holding the down tube in a Park stand and using some rod or pipe in the head tube to balance it in place.
This step has nothing to do with the jig - I'm just including it for continuity. Refer to the Paterek manual for more information.
Step 9: Pieceing Together the Front Triangle
Now we will join the two halves of the front triangle together. Again, I am skipping the mitering and other steps.
At the front of the jig under where the head tube will end up, drill and tap a set of two holes to hold leveling bolts.
Using the two leveling bolts under the head tube,

Does iPhone Voicemail Use Data? Visual Voicemail Explained.
Visual voicemail revolutionized voicemail when it was introduced alongside the first iPhone in 2007. We were used to calling a phone number, entering our voicemail password, and listening to our messages one at a time. Then came the iPhone, which changed the game by integrating voicemail into the Phone app with an email-style interface.
Visual voicemail lets us listen to our messages out of order and delete them with the swipe of a finger. This was no small feat for Apple developers, who worked closely with AT&T to create a seamless interface between the iPhone and AT&T's voicemail server. It was well worth the effort, and it changed voicemail forever.
In this article, I'll explain the basics of how visual voicemail works and answer a popular question asked by Payette Forward readers: Does visual voicemail use data? If you're having trouble with the voicemail password on your iPhone, check out my other article, "My iPhone Voicemail Password Is Incorrect".
From Answering Machines To Visual Voicemail
The concept of voicemail hasn't changed since the introduction of the answering machine. When cell phones were introduced, voicemail moved from a tape in your answering machine at home to a voicemail box hosted by your wireless carrier. In this respect, voicemail lived "in the cloud" before the phrase was every coined.
The voicemail we used with our first cell phones wasn't perfect: The touch-tone interface was slow and cumbersome and we could only listen to voicemail when we had cellular service. Visual voicemail fixed both those issues.
What Happens When You Receive Voicemail On Your iPhone
Your phone rings and you don't pick up. The caller is routed to a pilot number at your carrier that acts like an email address for your voicemail. The caller hears your greeting, leaves a message, and your wireless carrier stores your message on their voicemail server. Up until this point, the process is exactly the same as traditional voicemail.
After the caller finishes leaving you a message, the voicemail server pushes the voicemail to your iPhone, which downloads the message and stores it in memory. Since the voicemail is stored on your iPhone, you can listen to it even if you don't have cell service. Downloading voicemail on your iPhone has an additional benefit: Apple was able to build a new app-style interface that lets you listen to your messages in any order, unlike traditional voicemail where you had to listen to every voicemail in the order in it was received.
Visual Voicemail: Behind The Scenes
A lot happens behind the scenes when you use visual voicemail, and that's because your iPhone needs to stay in sync with the voicemail server hosted by your wireless carrier. For instance, when you record a new voicemail greeting on your iPhone, that greeting is immediately uploaded to the voicemail server hosted by your carrier. When you delete a message on your iPhone, your iPhone deletes it from the voicemail server as well.
The nuts and bolts that make voicemail work are essentially the same as they always were. The iPhone didn't revolutionize voicemail technology; it revolutionized the way we access our voicemail.
How To Set Up Visual Voicemail On Your iPhone
To set up voicemail on your iPhone, open the Phone app and tap Voicemail in the bottom right-hand corner of the screen. If you're setting up voicemail for the first time, tap Setup Now. You'll choose a 4-15 digit voicemail password and then tap save. After you enter your password again to make sure you haven't forgotten it in the last 5 seconds, your iPhone will ask you if you'd like to use a default greeting or a customized greeting. Voicemail
Default greeting: When a caller gets your voicemail, the caller will hear "You have reached the voicemail box of (your number)". If you chose this option, your voicemail box is ready to go.
Customized Greeting: You'll record your own message that callers hear when you don't pick up. If you choose this option, your iPhone will open a screen with a button to record your voice. When you're done, tap stop. You can tap the play button to make sure you like your message, record it again if you don't, and tap save when you're done.
How Do I Listen To Voicemail On My iPhone?
To listen to voicemail on your iPhone, open the Phone app and tap Voicemail in the bottom right-hand corner.
Does iPhone Visual Voicemail Use Data?
Yes, but it doesn't use much. The voicemail files your iPhone downloads are very, very small. How small? I used iPhone backup extractor software to transfer the voicemail files from my iPhone to my computer, and they're tiny.
How Much Data Does Visual Voicemail Use?
iPhone visual voicemail files use about 1.6KB / second. A one-minute iPhone voicemail file is less than 100KB. 10 minutes of iPhone voicemail uses less than 1MB (megabyte). For comparison, Apple Music streams at 256kbps, which translates to 32 KB / second. iTunes and Apple Music uses 20x more data than voicemail, and that's not surprising given the low-quality of voicemail.
DataIf you'd like to see how much data visual voicemail uses on your iPhone, go to Settings -> Cellular -> System Services.
It's important to note that if you're worried about using data, you can call your wireless carrier and remove visual voicemail. Voicemail would switch back to the way it always was: You'd call a number, enter your voicemail password, and listen to your messages one by one.
Wrapping It Up
Visual voicemail is great, whether you get one voicemail a month or one-thousand. It allows you to listen to your voicemail even when you don't have cell service or Wi-Fi, and you can listen to them in any order you like. We've covered a lot in this article, from the evolution of voicemail to how much data visual voicemail uses.

Definition: RTGS, is a short form for Real-Time Gross Settlement. It is a facility provided by the banks, that allows instant and complete settlement of funds from one bank to another and from one place to another, on an individual order basis. This means that the transactions are settled at the same time when they take place and so there is no waiting period.
Payments made through RTGS are final in nature which cannot be revoked. Moreover, the prescheduling of a transaction is allowed.
RTGS is mainly used for the high-value interbank transfer of money, in order to mitigate the risk of settlement and fraud.
Details Required for RTGS
The person (sender) who initiates the transfer must have the following details:
- Indian Financial System Code (IFSC) of the beneficiary's bank.
- Name of beneficiary
- Account number of the beneficiary
- Amount to be remitted
- Name of the beneficiary's bank and branch
- Account number of the sender/originator
Along with this, the bank branches of both the parties need to be RTGS-enabled, only then the transaction will be processed.
Minimum and Maximum Limit
This system is primarily developed to facilitate the transfer of large value funds between parties. Hence the least amount which is transferred through this system is Rs. 2 lakhs, while no maximum ceiling is there in RTGS.
Banks provide this service for a specified fee, wherein inward transactions are free, but a certain amount is charged on the outward transaction, depending upon the amount remitted.
How to do RTGS?
To transfer funds using RTGS, the first thing you require is the activation of internet banking facility. For this purpose, you need to visit your bank branch and complete the formalities for its activation. Nowadays, one can activate this facility online also using the concerned bank's website.
- Log in to the web portal, using the UserID and password.
- Once you enter the user ID and password, you will land at your account and profile where you have to select the profile.
- Thereafter click on Add and manage beneficiary.
- Then, you need to enter your profile password and click the submit button.
- You will see various options for adding a beneficiary, choose the relevant option as per your need.
- Upon clicking the appropriate option, you will be asked to fill the details of the beneficiary.
- Check the details and click on approve now button.
- Next click on the approve beneficiary radio button, where you will have two options – Approve through ATM, or Approve through OTP
- If you choose to approve through OTP, you will receive a high-security password at your registered mobile number, linked to the account. Now simply enter the password and click on approve button.
- Once the beneficiary is added the following steps are required to follow:
- Go to the payment/transfer tab and click inter-bank transfer.
- Select the Transaction Type, i.e RTGS and go to fund transfer section
- A list of beneficiaries will be displayed, select the beneficiary/payee
- Enter the amount to be transferred
- Select the checkbox stating that you agree with the terms of service and accept.
- Review the details and confirm.
In this way, the amount will be transferred successfully to the beneficiary's account.
Advantages of RTGS
- RTGS is one of the safest as well as the fastest mode of interbank transfer
- This facility is available on all business days, whose timings may vary from bank to bank.
- It is an immediate fund transfer mechanism.
- It is a paperless transfer of funds.
- The beneficiary is not required to visit the bank, to deposit the money.
- The funds can be transferred using the internet banking service.
Limitations of RTGS
- RTGS does not provide the facility to track the transaction to its customers, as only the positive confirmation feature is implemented by the central bank in which the remitting bank gets a message of fund transfer to the beneficiary bank, from the central bank.
In general, the beneficiary branches may receive funds in real-time, i.e. as and when the funds are sent by the remitting bank. The beneficiary bank has to credit the fund in the account of the beneficiary, within half an hour of the funds' transfer message.
However, if the funds are not transferred to the beneficiary's account due to the reasons like account frozen, or non-existence of account, then the funds are returned to the originating bank. Moreover, if there is a delay in refunding the failed amount, the initiating party is entitled to receive compensation at the current repo rate + 2%

Hydrostatic pressure is the ability of a fabric to seep under a certain pressure. It applies to all kinds of fabrics, including those that have been waterproofed.
The water resistance of the fabric is related to the water resistance of the fiber, yarn and fabric structure, and the measured results are different from that of water spray and rain on the fabric surface. The hydrostatic pressure method is used to measure the water resistance of fabrics, including static pressure method and dynamic pressure method. Static pressure method is to apply hydrostatic pressure on one side of the fabric, and measure the hydrostatic value under the hydrostatic pressure, the time of water drop, and the hydrostatic value at a certain amount of water flow. The hydrostatic value can be the height of the column of water or the pressure. In the actual measurement, the water penetration per unit area and per unit time (mL/cm2·h) is measured. For waterproof fabrics, measure the time it takes for water droplets to appear on the other side of the sample, or observe the amount of water droplets on the other side after a certain period of time.

Copy citation to clipboard
The aim of this document is to assess the potential health risks related to communicable diseases and other health threats for EU/EEA citizens during their stay in Saudi Arabia for the Hajj pilgrimage between 19 and 24 August 2018.
Executive summary
Due to the vaccination requirements for travelling to Mecca, Saudi Arabia, and the preparedness plans put in place by the host country addressing the management of health hazards during and after the Hajj, the overall risk for EU/EEA citizens of becoming infected with a contagious disease during the 2018 Hajj in Saudi Arabia is considered to be low. The risk of communicable disease outbreaks is highest for food- and waterborne diseases and respiratory illnesses, but the risk is not considered higher than can generally be expected for international mass gatherings of this size. MERS-CoV activity continues to be reported in the Arabian Peninsula, specifically from Saudi Arabia, and therefore imported cases may be detected in Europe following the Hajj. The risk of transmission of other vaccine-preventable and vector-borne diseases is considered to be low. The national health authorities in countries from where Muslims embark on the Hajj pilgrimage to Mecca should apply appropriate strategies for the prevention and control of communicable diseases before, during and after the completion of the Hajj.

What Happens If You Swallow Dental Floss?
When a person swallows dental floss, the body usually does not have any problems, and the dental floss passes through undigested, states ZocDoc. On rare occasions, it causes a blockage in the stomach or intestines or causes two loops of bowel to become stuck together.
Symptoms of a blocked GI tract are nausea, discomfort, abdominal swelling and the inability to pass gas or stool, advises ZocDoc. This is a serious condition that may require surgical intervention. If the dental floss gets caught and ties two bowel loops together, they may become fused, resulting in a serious condition that also may require surgery to correct.

The swivel rod ends is sensitive to the damage of the rod end joint bearing during operation. For example, its peeling, indentation, rust, crack, wear, etc. are reflected in the vibration measurement of the rod end joint bearing, so The special rod end joint bearing vibration measuring device (frequency analyzer, etc.) can measure the magnitude of the vibration, and the specific situation of the abnormality cannot be inferred by the frequency division. The measured value differs depending on the conditions of use of the rod end joint bearing or the position at which the sensor is mounted. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
The temperature at the end of the swivel rod can be inferred from the temperature outside the product when it is used. It is more suitable to directly measure the temperature of the outer ring of the rod end joint bearing by using the oil hole during the operation. Usually, the temperature of the rod end joint bearing starts to rise slowly as the rod end joint bearing starts, and reaches a steady state after 1-2 hours. The normal temperature of the rod end joint bearing varies depending on the heat capacity, heat dissipation, speed and load of the machine.
If the lubrication and installation parts are suitable, the temperature of the rod end joint bearing will rise sharply, and abnormal high temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions. The thermal sensor can be used to monitor the working temperature of the rod end joint bearing at any time, and automatically alarm or stop the occurrence of the burning shaft accident when the temperature exceeds the specified value. _URL_


What is the most efficient way to read a bit at a particular position in a byte?
Re: Most efficient way to read a bit from a byte? 80 80
By definition the byte is the smallest size object that can be addressed, so you have to read the whole byte and work with that.
Off the top of my head, I can't think of anything likely to be faster than the simple and obvious approach, particularly if the compiler can identify and optimise.
if (byte & 8) \\ i.e. if (byte & b00001000) - testing for bit marked one
Maybe someone has some super-fast cleverness, though.
Re: Most efficient way to read a bit from a byte? 80 80
Here is a sample of code to test for a set bit. Adapt as necessary.
#include <stdio.h>
int main(void)
{
 unsigned char target_byte = 0x81;
 unsigned int i = 0; /* Always initialize variables - much safer! */
 for (i = 0x01; i <= 0x80; i = (i << 1))
 {
 fprintf(stdout, "Reading bit %.02x\n", (unsigned char) i);
 if ((unsigned char)i & target_byte)
 {
 fprintf(stdout, "Bit %.02x is set\n", (unsigned char)i);
 }
 }
 return 0;
}
Re: Most efficient way to read a bit from a byte? 80 80
What is the most efficient way to read a bit at a particular position in a byte?
Amazingly enough, it depends on the bit in question. A general approach to reading any bit neglects tricks for reading specific bits more concisely (ie. using fewer instructions), and thus "faster".
Re: Most efficient way to read a bit from a byte? 80 80
Using the right shift (>>) operator is the quicker, if not the quickest, method.

Brain injury turns Italian man into Frenchman with poor language skills
Article content
A brain injury has turned an Italian man French, even though he doesn't speak the language very well.
Scientists from the University of Edinburgh and the Somma Lombardo Hospital in Italy, detailed the man's odd condition in the medical journal Cortex.
The man, who is 50 and described only by his initials, JC, had a brain injury stemming from an arterial anomaly four years ago. Abruptly afterwards, he began to talk in French. He only reads French magazines, enjoys French movies and eats French food.
The researchers said JC's previous history with French amounted to high school language classes and a "fling" with a French woman while the man was in his 20s. This was the first time he had used the language in 30 years.
Despite his newfound desire to speak French -- what the scientists call a "compulsive foreign language syndrome" -- JC still can't speak it very well.
But what he lacks in accuracy, he makes up for in "exaggerated intonation," the scientists say.
And he doesn't let it get him down: "unjustified euphoria," they call it -- even offering to teach his neighbours how to speak French.
"When a trauma to the brain occurs -- due to a car accident or a stroke, tumour, or other causes -- some parts of the network may be spared while some others temporarily or irreversibly damaged," Regina Jokel, a speech-language pathologist told ABC News in 2010, after studying a Croatian teen who began speaking German.

In mathematical logic, the Law of Syllogism says that if the following two statements are true:
(1) If p, then q.
(2) If q, then r.
Then we can derive a third true statement:
(3) If p, then r.
If the following statements are true, use the Law of Syllogism to derive a new true statement.
1) If it snows today, then I will wear my gloves.
2) If I wear my gloves, my fingers will get itchy.
Let p be the statement "it snows today", let q be the statement "I wear my gloves", and let r be the statement "my fingers get itchy".
Then (1) and (2) can be written
1) If p, then q.
2) If q, then r.
So, by the Law of Syllogism, we can deduce
3) If p, then r
If it snows today, my fingers will get itchy.


text: A mathematical model and a numerical solution procedure are developed to simulate flow field through a 3D permeable vessel with multibranches embedded in a solid tumour. The model is based on Poisseuille's law for the description of the flow through the vessels, Darcy's law for the fluid field inside the tumour interstitium, and Starling's law for the flux transmitted across the vascular walls. The solution procedure is based on a coupled method, in which the finite difference method is used for the flow in the vessels and the boundary element method is used for the flow in the tumour. When vessels meet each other at a junction, the pressure continuity and mass conservation are imposed at the junction. Three typical representative structures within the tumour vasculature, symmetrical dichotomous branching, asymmetrical bifurcation with uneven radius of daughter vessels and trifurcation, are investigated in detail as case studies. These results have demonstrated the features of tumour flow environment by the pressure distributions and flow velocity field. Copyright © 2012 John Wiley & Sons, Ltd.

Through a Treehugger's article on kinetic LED chandelliers we found something interesting about the subject.
A British interdisciplinary studio called Troika offers „a tantalizing glimpse" of what energy efficient lighting could bring, whirling geometric light forms.
„Thixotrope" the kinetic LED chandellier is made by eigh mechanical and illuminated structures of tensed steel banding outfitted with rows of LED lights. It is temporary installed in the London's Selfridges departament store.
Designers described it being a: „continuously revolve around their own axis thereby materializing the path of the light and dissolving the spinning structures into compositions of aerial cones, spheres and ribbons of warm and cold light while giving life and shape to an immaterial construct."
To use LED lighting is more than vital in creating space, is energy efficient.

Depending on origin, producer, exporter and loading port the qualities of sugar cane molasses can vary heavily.
Molasses is made up of residual ingredients of the processed sugar cane as well as traces from used additives in different proportions, depending on whether the sugar production method is used. Based on usage the following ingredients are viewed as the main quality determiners. The sugar content of sugar cane is typically termed as saccharose or total sugar, the dry matter as Brix or it is displayed as water / drymatter.
The quality of non-standardized cane molasses can vary within the following benchmarks:
| Saccarose|| 25 to 39%|
| Invert|| 12 to 19%|
| Brix|| 77 to 86%|
| Ash|| 8 to 14%|
| Raw protein|| 4 to 6%|
Depending on usage, this commodity is traded in different forms. For fermenting purposes mainly based on analysis or sample report with a price setting pro – rata calculation of the sugar content.
