What is a Pseudolite?
A pseudolite (or pseudo-satellite) is any device that performs a specific task that would otherwise require a satellite. So, for example, a dedicated transmitter might be deployed to extend the reach of a GNSS to areas where the satellite signals are either blocked or jammed, and there has been considerable success with deployment of pseudolites to extend GPS coverage indoors. These are relatively simple devices that only transmit the coarse acquisition code.
Pseudolites are also used to simulate future GNSS satellites in a real-world environment as well as for robotic guidance in space exploration.
A single-channel GNSS simulator (or signal generator) can be used as a pseudolite, particularly in the research and development arena. However, care needs to be taken when operating powerful transmitters within GNSS bands. Clearly, highly sensitive GNSS receivers designed to capture minute signals from distant satellites will not react well to high-power transmissions on their receiving frequencies.

Retention At STCC
Can a college examine student retention prior to defining what retention is to the particular institution? There is currently one standard, national retention definition that was established by the federal government and must be reported by all colleges on an annual basis. That definition is:
Program Retention: Tracks the full-time student in a degree program over time (6yrs/4yr college, 3yrs/2yr college) to determine whether the student has completed the program.
Center for the Study of College Retention: Retention
This cohort-based rate is the rate from which the Federal Student Right to Know Graduation Rate is calculated. But this retention definition does not include students who carry less than a full-time load in their first semester at the college. At STCC, this rate represents about 50% of our incoming class on average.
- Course Completion Rates
- Course Pass Rates
- Focus Group Findings for Post Traditional Students 2013
- Retention Analyses 2013
- Fall to Spring Retention Rates - Overall & By Gender
- Fall to Spring Retention Rates by Ethnicity & Student Type
- Placement & Retention Analysis of General and NonGeneral Studies Students.
Fall to Fall
- Cohort: A cohort is a body of students that have something in common. This can be start term; enrolled term; their program or course; or a demographic profile such as gender, race, service received, or academic placement.
- First-time: A first-time student is one who is attending STCC for the first time.
- Freshman vs Transfer: A freshman never attended college previously while a transfer is a student who has prior college experience whether they are transferring in credits from another institution or not.
- New Student: A student enrolling in credit bearing courses
- Census Date: The date the college takes an official snapshot of the term enrollment. It is also called the freeze date.
Types of Retention Reporting
- Course Retention: The Course Completion Rate is the number of
students enrolled in each credit course after the course census
date divided by the number of students who successfully complete
the course and earn a grade of D- or better at the end of the term.
- For Achieving the Dream, this definition is modified to a Course Pass Rate that reflects the number of students who successfully complete the course and earn a grade of C or better at the end of the term.
- Student Retention: Tracks the students' enrollment patterns.
There are three relevant time frames:
- Term to Term tracks the student enrollment pattern across consecutive terms Fall to Spring or Spring to Fall.
- Year to Year tracks the student enrollment pattern across consecutive years Fall to Fall or Spring to Spring.
- Progressive Retention tracks an incoming class (term cohort) through their academic experience.
Definition of Institutional Cohorts
The term-based Cohort used to calculate a retention rate can be based on one of many definitions. STCC reports:
- Total Term Headcount = All students enrolled with registered credits in a specific term.
- National Cohort = All first-time, full-time degree-seeking Freshman in a specific term.
- Freshman (CSRDE) Cohort = All first-time degree-seeking Freshman full or part-time in a specific term.
- Incoming (ATD) Cohort = All incoming degree-seeking first-time freshman or transfer students in a specific term.
- Persisting (BHE) Cohort = Any new students in a specific term who attempted at least 18 credits within two years of initial enrollment and did not enroll in ESL.
- Concentrator (Perkins) Cohort = Any student who has earned 12 credits by the start of a specific term.

GRANGER —The International Catholic Stewardship Council (ICSC) named St. Pius X of Granger as a runner-up for the Archbishop Thomas J. Murphy Award on Oct. 13. Julie Kenny, from Our Sunday Visitor and a member of the ICSC board of directors, accepted the award on the parish's behalf in Dallas, Texas.
According to Michael Murphy, executive director of the ICSC, this award recognizes parishes that give witness to stewardship in many areas of parish life. St. Pius X was one of only five parishes in the country to receive this distinction.
St. Pius X "demonstrated their commitment to exercising stewardship in pastoral areas such as prayer and worship, formation and education, offering hospitality, cultivating leadership, communications and promoting among their parishioners the stewardship of time, talent and treasure," Murphy emphasized.
Scott Bader, vice president of the ICSC and director of parish stewardship for the Archdiocese of Seattle, explained that St. Pius X helps to set the standard in stewardship for parishes nationwide: "St. Pius X Parish is a superb example of how a parish can build up the individual and collective practice of faith through stewardship. The parish is one we definitely suggest others consider emulating."
In 2007, Betsy Quinn, the director of stewardship and evangelization at St. Pius X, oversaw the creation of a stewardship core team, which worked to develop a comprehensive, multiyear strategic plan for stewardship and development. Areas highlighted in the plan include volunteer appreciation, communication, education/catechesis, outreach and welcoming and hospitality.
Specific programs that have resulted from the plan include development of an adult education program, enhancement of the parish welcoming committee, formation of a young adult ministry and expansion of youth activities.
"With a large parish, of over 3,000 families, we are challenged to keep a tight-knit, community feel. By having an ongoing and active stewardship program, we are creating a true Christian atmosphere founded on the pillars of stewardship: hospitality, prayer, formation and service," said Quinn.
She added, "We are always striving for conversion in the hearts of our parishioners, young and old, to embrace the stewardship message: from new parishioners to our founding families, at baptisms and at funerals, in our children's religious education programs and through adult education opportunities, at social events, and, most importantly, at Sunday liturgies. Through the leadership of Father Bill Schooler, Father Bob Lengerich, the parish staff, and the commitment of our dynamic Stewardship Core Team, we are continually finding ways to contribute to the conversion journey."
Father Schooler credited Quinn's leadership as key to the recognition of St. Pius X by the ICSC. "Betsy Quinn is the reason we received this award from the national stewardship council. She has worked tirelessly to promote stewardship as a way of life at St. Pius and to educate parishioners on what it really means to be a good steward."
Quinn, Father Schooler and the St. Pius X community were congratulated by Bishop John D'Arcy for their stewardship efforts. Father Schooler noted that St. Pius X gave the St. Vincent de Paul Society $81,000 in food and direct grants last year. In addition, the parish gives 5 percent of its income to the parish school of St. Adalbert in South Bend and 2 percent to local, national and international needs of the poor annually.
"That truly is an act of faith by the parish," Bishop D'Arcy stressed.

Family: Aulostomidae, Trumpetfishes view all from this family
Description Trumpetfish, Aulostomus maculatus, are long bodied fish with upturned mouths, that often swim vertically while trying to blend with vertical coral, like sea rods, sea pens, and pipe sponges.
Trumpetfish occur in waters between 0.5 and 30 meters (1.6 and appr. 100 feet) deep and can grow to 40 to 80 cm (appr. 15 to 31 inches) in length. They are sometimes locally abundant over coral atoll reefs or in lagoons, where they may be caught even in areas of severe wave action. The spawning habits of the trumpetfish are unknown, but in the region around Madeira, it is known that the females have mature eggs from March to June.
Trumpetfish are closely related to cornetfish. Trumpetfish can be a bit more than 36 inches (3 ft) long and have greatly elongated bodies with small jaws at the front end of a long, tubular snout. The gills are pectinate, resembling the teeth of a comb, and a soft dorsal fin is found near the tail fin. A series of spines occurs in front of the dorsal fin. Trumpetfish vary in color from dark brown to greenish but also yellow in some areas. A black streak, sometimes reduced to a dark spot, occurs along the jaw, and a pair of dark spots is sometimes found on the base of the tail fin.
Trumpetfish swim slowly, sneaking up on unsuspecting prey, or lie motionless like a floating stick, swaying back and forth with the wave action of the water. They are adept at camouflaging themselves and often swim in alignment with other larger fishes. They feed almost exclusively on small fish, such as wrasses and atheriniformes,by sucking them suddenly into their small mouths.
Trumpetfish make up the genus Aulostomus of the family Aulostomidae.
Habitat Ocean or bay shallows, Estuaries, tidal flats & salt marshes, Tidepools.
Range Southeast, Florida, Texas.

Why are tomatoes red? The same reason dinosaurs were killed off, say scientists. The massive meteorite that struck Earth 60 to 70 million years ago created extremely harsh conditions that forced the evolution of the tomato into its current red and edible form, reports Phys.org. Researchers discovered this connection by mapping the complete tomato genome and finding that the number of tomato genes suddenly tripled near the time of the meteorite impact.
"Such a big genome expansion points to extremely stressful conditions," says one of the researchers. As the theory goes, the solar eclipse that followed the meteorite crash would have made it difficult for plants to live. "A distant ancestor of the tomato plant then reacted by expanding its genome considerably in order to increase its chances of survival." In time, the tomato shed some of the other characteristics it picked up, but its redness stayed.

You talkin' to me? Male fiddler crabs pick fights, even if they know their replacement claws put them at a disadvantage.
Crabs That Fib
When tangling over territories, some male fiddler crabs win by pretending to be stronger than they are, a new study reveals. The research adds to earlier findings that suggest animals use dishonesty more often than previously thought.
Male fiddler crabs sport an enormous claw, which can regrow if lost during a fight over a home burrow. Although the replacement looks the same as the original, it is much weaker. The crabs notice the difference in their new claw, because it is lighter and does not pinch or pull as well. However, when faced with a challenger, they act as if nothing's wrong, displaying their feeble--but large--claws threateningly. The bluff usually works, according to a team of Australian ecologists who report their findings this week in Functional Ecology.
The researchers collected Uca mjoebergi fiddler crabs in Darwin, Australia, and identified those with original claws and those with replacements. They measured closing force and pulling force--in territorial fights, invading crabs try to yank residents from their homes. The researchers then released the crabs near their original burrows and watched as other males challenged them.
Homeless crabs with regenerated claws that were searching for a new burrow usually picked on crabs with smaller claws. Most of the time, the resident crabs gave up their burrow without a fight, falling for the bluff. "Male performance traits, such as claw strength and pull-resisting force, are really the key to success in male combat, so much so that the males will pretend to be good performers even if they are not," says lead author Simon Lailvaux, an evolutionary ecologist at the University of New South Wales in Sydney, Australia.
However, resident crabs with new claws defending their homes against homeless crabs had no choice over opponents, because they had to fight whoever attacked. When challenged, residents still tried to bluff, though they weren't as successful as the deceptive invaders. Those whose bluff was called usually lost the fight because of their weaker claw.
Honesty in signaling is a growing area of interest for many scientists who study sexual selection and communication systems in animals. Work such as this--as well as similar research in crayfish, bull frogs, and hermit crabs--goes a long way toward explaining how animals rely on dishonesty to maintain territories and attract mates, says Jonathan Rowell, a biological mathematician at the University of North Carolina, Chapel Hill, who was not part of the study. "The big issue is trying to determine whether a behavioral pattern such as dishonesty is genetically hard-wired into the [species] or if it's just an individual behavior," Rowell says.

During Drosophila gastrulation, the ventral mesodermal cells constrict their apices, undergo a series of coordinated cell-shape changes to form a ventral furrow (VF) and are subsequently internalized. Although it has been well documented that apical constriction is necessary for VF formation, the mechanism by which apical constriction transmits forces throughout the bulk tissue of the cell remains poorly understood. In this work, we develop a computational vertex model to investigate the role of the passive mechanical properties of the cellular blastoderm during gastrulation. We introduce to our knowledge novel data that confirm that the volume of apically constricting cells is conserved throughout the entire course of invagination. We show that maintenance of this constant volume is sufficient to generate invagination as a passive response to apical constriction when it is combined with region-specific elasticities in the membranes surrounding individual cells. We find that the specific sequence of cell-shape changes during VF formation is critically controlled by the stiffness of the lateral and basal membrane surfaces. In particular, our model demonstrates that a transition in basal rigidity is sufficient to drive VF formation along the same sequence of cell-shape change that we observed in the actual embryo, with no active force generation required other than apical constriction.

How to Get Mold Smell Out of Dresser Drawers
Mel Frank
Dressers are a perfect way to store clothing, keeping it safely out of sight yet on hand and quickly accessible. The problem is that these drawers are dark, typically sealed off when closed, and can quickly develop moisture that leads to the development of a musty, moldy odor. To remove the odor, simply treat the drawers with a quick odor removal solution.
Get rid of mold smell with ease.
 1. Place a small dish of baking soda in each drawer. The baking soda is a natural odor absorbant that will also draw any moisture out of the drawers. Let the baking soda sit overnight.
 2. Fill a spray bottle with white vinegar. The vinegar is a deodorizing agent and will also kill any mold or mildew growth that is causing the odor.
 3. Spray the vinegar solution into all of the drawers.
 4. Keep the drawers open, and allow the drawers to air out overnight.
 5. Repeat if needed if all odor has not dissipated.

Abandoned mineshafts could be used to heat Glasgow
by James Morgan
15 February 2013
In certain cases, it will be necessary to dig up streets in order to install new pipes and cables. I think that working out how to do this will prove to be the biggest challenge. However, a lot of our work is likely to be carried out in conjunction with new developments in which a centralised heat-pumping system will distribute water around houses and offices.
Experts from Glasgow Caledonian University (GCU) believe that disused coal mines could help to solve the problem of fuel poverty within Scotland's largest city. The researchers, whose work is being partly funded by ScottishPower Ltd, suspect that the warm water contained within Glasgow's abandoned mineshafts can be used to heat roads, pavements and homes.
This might sound too good to be true, but Glasgow wouldn't be the first city in the world to adopt such an approach. Hamburgers and Stockholmers already enjoy similar systems that take advantage of the geothermal energy beneath their feet. If the team – led by Project Director Dr Nick Hytiris, Senior Lecturer at GCU's School of Engineering and Built Environment – concludes that Glasgow is a suitable candidate for such a system, it has been calculated that the subterranean water supply could provide heating for approximately 40 per cent of the city's population.
To find out more about the benefits that might result from this network of almost-forgotten mineshafts, I spoke to GCU's Bjørn Aaen, a participating researcher and former technical advisor to Glasgow City Council. I began by asking how he and his colleagues plan to identify reservoirs with the potential to fuel this under-street heating system.
"We will begin by studying the maps that have already been developed by Glasgow City Council and the British Geological Survey (BGS)," Aaen replied. "These 3D models are really detailed representations of subterranean Glasgow, and they show that there are reservoirs of water stored within the city's old mine workings. The trick will be to identify the best reservoirs to use. Utilising very shallow mine workings, for instance, could cause problems relating to instability. Having said that, any water that we draw from reservoirs will be pumped back again, so there should be very little overall change in volume.
"Even so, it might be more sensible to choose reservoirs that exist at a depth of about 50m or so," he continued. "At these levels, the temperature doesn't tend to vary with the seasons. You don't have to go very deep into the ground to find water with a temperature that remains stable all year round."
Of course, assuming that Aaen and his colleagues do find a sufficient number of reservoirs to make this project economically viable, it still remains for them to pump the warm water to the places in which it is needed. I asked how difficult it would be to integrate such a system within Glasgow's already bustling underground infrastructure.
"To some extent, this depends on the distance that the water has to travel," Aaen explained. "In certain cases, it will be necessary to dig up streets in order to install new pipes and cables. I think that working out how to do this will prove to be the biggest challenge. However, a lot of our work is likely to be carried out in conjunction with new developments in which a centralised heat-pumping system will distribute water around houses and offices. For example, we are going to be working in the Clyde Gateway Regeneration area; the largest regeneration area in Scotland. As we will be starting from scratch, installing geothermal heating systems will cause very little disruption. Naturally, we will do our best to avoid digging anything up without good reason."
In the United Kingdom, a household is said to be in fuel poverty if – in addition to meeting the costs of utilities such as lighting, appliances, cooking and water heating – it spends more than 10 per cent of its income on maintaining a satisfactory heating regime.1 During recent years, energy prices have risen at a faster rate than the average income in Glasgow, leading to higher levels of fuel poverty across the city. Indeed, according to the 2008 Scottish House Condition Survey, 25 per cent of Glaswegian households are 'fuel poor'.2
In light of such statistics, I asked Aaen about the extent to which this initiative will provide heating for domestic purposes? How many people could benefit from Glasgow's geothermal energy resource?
"It has been calculated that during a 100-year period, up to 40 per cent of Glasgow's heating needs could be met by this energy resource," he replied. "It has the potential to make fuel costs more affordable for huge numbers of people. Moreover, there is existing evidence to this effect. The residents of Glenalmond Street have had this system installed for over a decade now. Whilst I am only talking about 17 houses – it is quite a small setup – the residents have reported that their heating bills have dropped to approximately £150 per year. Heating homes in this way is much cheaper than using gas or electricity."
Finally, I asked Aaen whether other UK cities are likely to follow suit if he and his colleagues find Glasgow to be a suitable host for this expansive geothermal heating infrastructure. As he explained, locations across the home nations could take advantage of their mining heritages.
"There are numerous towns and cities that exist above old mine workings similar to those that can be found beneath Glasgow," Aaen concluded. "Places across Central Scotland, England and Wales could certainly benefit from the same type of technology. After all, the remnants of mining past are spread widely across the UK and beyond."

Arthur D. Little Analysis Finds Further Problems with the Proposed Gas Directive Amendment
Arthur D. Little (ADL) today published two reports analyzing the EU Commission's proposals to extend the regulations of the Third Gas Directive to pipelines from third countries supplying gas to the EU. They find that the recent European Commission-Gazprom settlement makes the amendment unnecessary, and that the proposed legislation will fail in its objective of enhancing market competition, potentially even decreasing supply.
The proposed directive suggests expanding EU regulation to import pipelines from non-EU countries, risking potential legal challenges and future international investment in gas-export infrastructure. Existing agreements between Spain and Italy and third countries, such as Algeria, Libya, Tunisia and Morocco, would need to be renegotiated, creating scope for counter demands. The economic conditions for future pipeline projects such as East Med would become less predictable, creating the risk that gas would go to non-EU markets. Proposed derogations or exemptions cannot be guaranteed, and their outcome is uncertain. This could have a detrimental impact on supply, and therefore prices – the exact opposite of its stated aims.
The Spring 2018 settlement between the European Commission and Gazprom set out binding legal obligations, with mandatory actions agreed to prevent alleged anti-competitive behavior by Gazprom. This significantly changes the EU gas supply landscape, rendering the amendment unnecessary, according to ADL's analysis. Additionally, greater liberalization means the market is now beginning to function very well, without requiring further legislation.
Michael Kruse, Partner and Head of Energy & Utilities in Central Europe, explains: "The Gazprom settlement has significantly shifted the market context compared to when the Gas Directive amendment was first proposed. It creates a relevant, important change which needs to be recognized in the ongoing discussions around the amendment, and our analysis recommends carrying out a detailed impact assessment to check it is still necessary. At the very least, the European Commission should wait for the impact of the settlement to bed in, before introducing further changes."

If a faulty sensor is triggered by a faulty abs sensor, you can ask your doctor, doctor's office, or a local hospital to get you a new test. In some cases, it's even better to get a new test done every day.
Some people have to take it seriously, and some even do it on a daily basis. The point is to keep your head down and be able to keep your head above water.
When a faulty sensor triggers a faulty abs sensor, it's possible to get an idea what this sensor is doing. A faulty abs sensor is one of the most common sensors in the world. If a faulty sensor is triggered by a faulty abs sensor, it could cause a whole series of problems. The most common problem is that the sensor's response is limited, and sometimes not enough.
The trouble with faulty sensors is that they don't work very well. When a faulty sensor fires a faulty abs sensor, a whole series of problems are likely to occur, and a whole lot more problems are likely to occur. The fact is that when a faulty sensor fires a faulty abs sensor, there is a huge chance that this sensor will trigger another sensor to fire. If that sensor fires again, the sensors response is going to be very poor.
As it turns out, one of these sensors is firing both of the other sensors to trigger another sensor, and the sensors response has been very poor. A faulty sensor can cause the abs sensor and the other sensor to fire at the same time, resulting in a large number of fire-and-forget explosions and the like. The sensors response can be very poor, and it can happen with even a single sensor. That is why you should always check for sensor problems on your own home.
The problem is that the sensors response is so bad that you can't go about the task of figuring out when they're going to fire. That is because when they're firing, you don't have a way to determine the location of the sensor, but rather a way to know when the sensor is going to fire. And to that end even a single sensor is almost impossible to determine.
The best way to know when youre in trouble is to have someone else do it for you, so that you can take action. In this case it was Robyn from the team at Sensormatic.
Some of the sensor sensors are in the same category as the other five sensors you listed above, but they are not listed as being a "super-sensor" or "super-sensor" in the same way.
You have a sensor that can detect when you are in the vicinity of the ground and can be triggered by this ground sensor. Your car can also "beep" to tell you when you have stopped in your lane, and then have to be "pulled over" to the side.
If you're in doubt whether your car is on the highway, you can use the "Warning!" indicator. This will give you an email or text message alerting you that a "warning!" sensor has been triggered.


Console Fingerprinting: Not a Big Threat, But We'll Do It Anyway
2023-09-28
The web console provided by modern browsers offers developers invaluable insight into their web applications. However, variances between browser implementations also introduce the possibility of using the console as a fingerprinting vector. While console fingerprinting is unlikely to be deployed in the wild, here at personaldata.info, we try to fingerprint everything we can get our hands on. It serves as an illustrative example of how nearly any browser feature can aid fingerprinting efforts.
Accessing the Console
The console is accessible via the global console object in any browser context. For example:
console.log("Hello world!");
Will output the string "Hello world!" to the console in all major browsers.
Beyond logging output, the console object also exposes various utility methods like console.error(), console.warn(), and console.time(). The full set of methods available varies between browsers.
Styling Console Output
One simple test is styling console output using CSS. For example:
console.log("%cBlue text", "color: blue;");
Will output the text "Blue text" colored blue in supporting browsers. Support for styled output differs across browsers. Most modern browsers support css styled console logs, but some older browsers may not. So this simple test already allows distinguishing between some browsers.
Emoji Support
Just like styled output, printing emoji characters to the console is another area where browser support may vary. Some older browsers may lack support for logging emoji characters to the console. Testing for emoji support simply involves logging a test emoji to the console:
console.log("🎉 Party time!");
If this throws an error, emojis are not supported. Being able to print emojis to the console indicates a more modern browser build. So testing for emoji support produces another variance that aids fingerprinting efforts.
Console Methods
The set of functions exposed by the console object creates significant potential for fingerprinting. Looping through the console object reveals the available methods:
for (let method in console) {
 if (typeof console[method] === "function") {
 console.log(method);
 }
}
Running this in various browsers demonstrates small differences in exposed functions between Chrome, Firefox, and Safari.
For example, Firefox lacks support for console.createTask(), where Chrome supports it. Another example is in Firefox console.exception is an alias for error(). Along with those, the order in which these methods appear in the console object can also aid in fingerprinting because, in most hashing algorithms, the order in which items appear will result in different hashes.
Fingerprinting Method
To create a console-based fingerprint:
 1. Test for styled output support.
 2. Print an emoji character.
 3. Loop through available console methods.
 4. Output sample data to test for extension behaviors.
 5. Hash the results into a fingerprint string.
For example:
// Helper to hash text with SHA-256
function hash(text) {
 return crypto.subtle.digest("SHA-256", new TextEncoder().encode(text))
 .then(buffer => {
 return Array.from(new Uint8Array(buffer))
 .map(b => b.toString(16).padStart(2, "0"))
 .join("");
 });
}
async function getConsoleFingerprint() {
 let results = [];
 // Test styled output
 console.log("%cStyling test", "font-size: 2em");
 if (/%c/.test(console.log.toString())) {
 results.push("styled");
 } else {
 results.push("plain");
 }
 // Test emoji output
 try {
 console.log("🎉");
 results.push("emoji");
 } catch {
 results.push("no emoji");
 }
 // Log methods
 let methods = [];
 for (let method in console) {
 if (typeof console[method] === "function") {
 methods.push(method);
 }
 }
 results.push('methods: ${methods.join(",")}');
 // Test for React DevTools
 console.log({name: "John", age: 30});
 // Hash and return fingerprint
 const fp = await hash(results.join(";"));
 return fp;
}
getConsoleFingerprint().then(fp => {
 console.log("Fingerprint:", fp);
});
This provides a simple characterization of the console environment, fingerprinting both browser differences and extension behaviors.
Limitations
While illustrative of the fingerprinting potential inherent in nearly any browser feature, console fingerprinting has limitations as a practical fingerprinting vector:
 - The console API is not available in all browsing contexts.
 - Very limited fingerprinting potential.
 - Just like any other fingerprinting method, console fingerprinting, while limited, still raises privacy concerns.
Nonetheless, the console exemplifies the fingerprinting risks inherent in common browser APIs, even those intended for developers. Virtually any feature from CSS support to audio contexts to device sensors can be probed for identifying variances. With privacy and fingerprinting concerns on the rise, browser vendors face increasing pressure to limit access to APIs or reduce the fidelity of their implementations.
Conclusion
While the browser console may initially appear to be an unlikely vector for fingerprinting, it harbors distinctive traits like styling peculiarities, emoji compatibility, unique API methods, and extension adaptations that can reveal identifying information. However, the question of whether console fingerprinting should cause alarm leads us to a reassuring answer: No, it typically reveals a minimal amount of information and is rarely employed in commercial applications.
The primary objective of this brief post was to shed light on the latent fingerprinting potential concealed within most browser features. The console exemplifies how even unlikely features can aid in fingerprinting if there are variations between different devices and browsers. Browser vendors should follow the principle of data minimization, granting access only to information essential for web applications. With privacy and fingerprinting concerns on the rise, developers and vendors alike must make privacy and security foundational priorities in all aspects of browser design.

What is covered in this training product?
When the need arises to create complex effects and custom setups within your Softimage project, many artists elect to use ICE, a visual programming environment included with Softimage that allows artists and technical directors to create custom solutions for many of the challenges associated with working on visual effects and animation for production.
One of the latest features to be integrated into Softimage, is the amazing Lagoa Multiphysics system. Lagoa can perform many tasks that are useful for achieving complex effects and projects. It can be used to simulate breakable materials, cloth, advected meshes, fluids, and more. Lagoa is completely integrated within Softimage via ICE, in fact, you use it within ICE, making it as much a part of Softimage as any other compounds or effects created inside ICE. Lagoa is not a plugin and there is no additional installation necessary, simply open Softimage as usual and start creating effects immediately.
In this training product, you'll be shown how to work with Lagoa from start to finish. We'll begin your journey into Lagoa by getting started with the basics of Lagoa and understanding all the nodes and properties that comprise a typical range of Lagoa effects. From there, following a healthy series of example projects, you will be shown; creating and working with complex fluid simulations, implementing motion blur with Lagoa correctly, creating soft body effects, creating cloth and mesh advection effects, creating and implementing Lagoa Post Sim Effects, creating multi-phase systems, working with and creating substance materials, using emPolygonizer to mesh your Lagoa effects, creating realistic effects both through physical accuracy and visual aesthetics, and more. As if that wasn't enough, you'll also learn tricks and techniques for optimizing and caching your Lagoa effects and meshes in order to speed things up and get the best interaction with Lagoa that you can. This training product includes all project files and assets needed to follow along with the instructor. Project files require Autodesk Softimage 2012.

Who invented tarred roads?
Edgar Purnell HooleyTarmacadam is a road surfacing material made by combining macadam surfaces, tar, and sand, patented by Welsh inventor Edgar Purnell Hooley in 1902.
The terms "tarmacadam" and tarmac are also used for a variety of other materials, including tar-grouted macadam, bituminous surface treatments, and modern asphalt concrete..
Is Tar toxic to humans?
The International Agency for Research on Cancer (IARC) has determined that coal tar is carcinogenic to humans and that creosote is probably carcinogenic to humans. EPA has also determined that coal tar creosote is a probable human carcinogen.
Is road tar toxic?
When hot asphalt is applied in a molten state, it generates toxic fumes. Workers exposed to asphalt fumes are at risk of developing headaches, rashes, cough, and possibly cancer. There is no OSHA standard for asphalt fumes.
What is the black stuff on roads?
According to Wikipedia, bitumen is defined as a black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. It is used for road surfacing and roofing. An asphalt concrete mix actually contains aggregate as well as a bituminous mixture.
Can you do your own asphalt?
Making your own asphalt driveway is hard work, and not a job for one person. If you have friends who will help you, it is possible to save a lot of money by doing your own driveway, even after the cost of rental equipment is factored in.
Is tar used to make roads?
During the early and mid-20th century, when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of coal tar to macadam roads led to the word "tarmac", which is now used in common parlance to refer to road-making materials.
Is tar and asphalt the same thing?
The main difference between Tar and Asphalt is that the Tar is a substance and Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum; bitumen variety. … Tar-like products can also be produced from other forms of organic matter, such as peat.
What is road tar made of?
Tar is refined natural resin or 'pitch', usually from the wood and roots of pine trees, but these are rarely found in our pavements. In fact, most of the 'tar' in tarmac is bitumen, which can be found in nature as a semi-solid form of petrol; but it is more commonly a bi-product of crude oil production by distillation.
Is asphalt cheaper than concrete?
Cost. Ignoring any maintenance costs, asphalt is generally much cheaper to install than concrete. On average, the cost per square foot for asphalt will run between $2.50 to $4.00. … It's not unheard of to have a stained concrete driveway with a smooth finish cost over $15.00 per square foot.
What causes white tar?
Naphthalene (also called white tar and tar camphor) is a white solid that evaporates easily. Its present in fuels such as petroleum and coal and has been used in mothballs and moth flakes. Burning tobacco or wood produces naphthalene.
Why are roads made tar?
The chip seal treatment is a cost efficient method of pavement preservation that helps prevent water from seeping into and softening the base of the road. … The tar-like substance is actually an emulsion of water and liquid asphalt which penetrates and seals small cracks in the existing pavement.
What are the three types of bitumen?
Three types of bituminous emulsions are available, which are Rapid setting (RS), Medium setting (MS), and Slow setting (SC). Bitumen emulsions are ideal binders for hill road construction. Where heating of bitumen or aggregates are difficult. Rapid setting emulsions are used for surface dressing work.
Is road tar flammable?
First, it must be recognized that all asphalt products, when heated enough, are flammable. That means that if you heat any asphalt hot enough, whether it is a cut back, an asphalt cement, or an emulsion, hazardous vapors will be produced.
Is tar a carcinogen?
A few carcinogens commonly found in tar include benzene, acrylamide and acrylonitrile. Smoking exposes delicate cells inside the lungs directly to these compounds. This causes mutations in the DNA of the cells, which leads to cancer.
Is Breathing asphalt bad?
Asphalt doesn't exactly scream danger or potential workplace illness, however, the fumes emitted from it can be very dangerous. Asphalt is a petroleum product which, if not settled properly, can catch fire. It can cause skin irritation, lung irritation and burns.
Can you make tar?
Tar can be produced from coal, wood, petroleum, or peat. Mineral products resembling tar can be produced from fossil hydrocarbons, such as petroleum.
Are roads made of cement?
Concrete is made using aggregate (like crushed rock and sand), along with cement and water. … When roads, parking lots or driveways are built using asphalt construction, hot asphalt (bitumen mixed with fine aggregate) is poured onto a bed of heavier aggregate and then pressed into it with a steamroller.

Does the size of the rain collecting vessel matter? In other words, does its diameter matter?
Nope, any diameter will produce the same result.
Why? the height of the water in the collector is equal to the volume of water in it divided by the area of its opening. The volume of water in the collector is proportional to the rate of rainfall (measured in something like drops per unit area) times the area of the can. If we put these together, we find that the area of the rain gauge cancels from the top and bottom of the ratio—meaning the area doesn't matter!
The only meaningful measure left is the height of the rain collected. Hence only mm or inches.
Another way to think about it is – if all the rain that fell didn't disappear (absorption in the ground, evaporation, etc.), and if there were a way to keep it in one location like it is in a vessel then it's height would stand at x mm, or inches, if you are like me :), in that location.
So, stating the measurement as volume would be misleading unless you also specified the amount of area on which that volume fell.

River crest expected at 18.6 feet, which is 3.6 feet above flood stage
The Mississippi River at Hastings is expected to reach flood stage Friday, March 19, and continue rising through the middle of next week.
In its latest flood warning update, as of March 16, the National Weather Service in Chanhassen is forecasting the river will reach flood stage of 15 feet by Friday. As of 10 a.m., Tuesday, March 16, the river was at 12.6 feet, an increase of more than two feet since Monday morning.
If the river reaches flood stage, the First Street railroad underpass begins to flood. That's it.
But in an effort to stay up to date, the city of Hastings will monitor the river levels and consider appropriate actions, Hastings Public Works Director Tom Montgomery told the Hastings City Council.
The National Weather Service predicts the river will continue to rise to a crest between 18 feet and 19 feet. Additional increases in the water level are possible after next week.
At the flood stage of 17 feet, water will be over the rip rap at Levee Park; at 18 feet, water is over the rip rap at Jaycee Park and may start to impact the basements of some of the homes on East First Street.
The Public Works, Parks, Police and Fire departments will coordinate efforts and close roads, trails and parks as appropriate. No city structures are expected to be impacted by flooding except for some structures in Lake Rebecca Park.
In the two most recent floods, 2001 and 1997, the city helped some homeowners on East First Street by providing empty sand bags and sand. Several employees and skid loaders moved pallets of filled sand bags to areas around the homes where they were needed.
Volunteers filled the bags and placed them. No city employees were used to fill bags.
If the flood stage reaches 16.5 feet and the forecast at the time is predicting levels to exceed 18 feet, then the city would use $10,000 from the critical incident equipment revolving funds to buy sand bags and other materials necessary to protect the homes.
The Mississippi River reached its highest level during the 1965 flood - 25.9 feet. Four years later, it reached 24.3 feet.
In 2001, the river actually had two crests, one at 21.6 feet April 17, and one at 22 feet April 29.

DiffPDF is used to compare two PDF files—textually or visually, is developed by Mark Summerfield, he said "In theory DiffPDF could be built on Windows, but I haven't managed to do it, so no Windows executable is available. The problem is that I don't know how to build the Poppler library on Windows (apparently it isn't easy!)." and I did some effort to compile to on windows. As I know it works on Windows XP and Windows 7 (both 32-bit and 64-bit Windows).
DiffPDF can compare two PDF files. It offers two comparison modes: Text and Appearance.
By default the comparison is of the text on each pair of pages, but comparing the appearance of pages is also supported (for example, if a diagram is changed or if a paragraph is reformatted). It is also possible to compare particular pages or page ranges. For example, if there are two versions of a PDF file, one with pages 1-12 and the other with pages 1-13 because of an extra page having been added as page 4, they can be compared by specifying two page ranges, 1-12 for the first and 1-3, 5-13 for the second. This will make DiffPDF compare pages in the pairs (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).
A couple of example PDF files are provided (boson1.pdf and boson2.pdf) so that you can try it out. PDF files can be loaded from the GUI (by pressing the File #1 and File #2 buttons), or by specifying them on the command line. I use the tool regularly to compare different versions of my books (which are typically 500 or more pages), e.g., comparing a first printing with a second printing, to make sure that only the pages I intended to change have actually been changed.
DiffPDF is licensed under the GNU General Public License v 2 open source license. To build it you will need a modern C++ compiler, the Qt 4 libraries (at least Qt 4.4; 4.6 or later recommended), and the Poppler library—all these should be available as standard packages on most Linux and BSD systems.
The source is diffpdf-1.8.0.tar.gz(40K). Building follows the standard pattern for Qt 4 applications and is explained in the README. Fedora, Debian, and Ubuntu users don't have to build it manually, they can simply install the binary
diffpdfpackage using their prefered package management tool—but make sure you get at least version 1.8.0!

- German translation (and many suggestions) from Rainer Krachten.
- Translations should "just work"; i.e., if you use a French locale then the user interface and help text should appear in French. However, you can force DiffPDF to use any language it supports by using the –language command line option (e.g., –language=fr). If an unsupported locale or –language option is used, DiffPDF will fall back to English.
- Now support -h as a synonym for –help.
- Initial path defaults to home directory instead of DiffPDF's installation directory.
- Improved the Options dialog's layout.
- A subtle bugfix to the –words command line option.
- Fixed a crash: clicking to set a margin when there're no PDFs loaded now safely does nothing.
- Can now have comparisons exclude text that's outside user-specified margins. This feature was sponsored by a company that prefers to remain anonymous.
- Save As can now save images as well as PDFs.
- Minor bug fixes and improvements.
- Command line help (–help) will no longer work on Windows. This is to avoid a spurious console window appearing. I've put the output in the online help though.
- Improved dock window handling so that docks can now be stacked on top of each other (useful for small screens).
- Added missing step to the README.
- Save As now preserves the aspect ratio. Bug reported by Rainer Krachten.
- Added Czech translation provided by Pavel Fric.
- Will now use the default locale's language for standard dialogs (e.g., for the file dialog).
- Dragging & dropping one or two files onto the filename line edits or onto the file viewer panels is now supported. Independently suggested by Liviu Andronic and Rory Gordon.
- Show Zones checkbox is always visible (it was only visible with –debug in earlier versions).
- DiffPDF now starts up with its initial comparison mode being whatever comparison mode was in force when it was shut down (or Words mode the first time it is run).
- Improved About box with more version info + contributors.
- Added –help command line option.
- Introduced zoning: this can be slow in Characters mode but can provide better accuracy in text modes.
- Improved Character mode to be as liberal about hyphens as Words mode.
- Minor doc changes that I forgot for 1.7.0.
- Minor GUI bug fixes and changes.
- Minor under the hood efficiency improvements.
- Renamed Text mode to Words mode. This mode is best for alphabetic text (e.g., English).
- Added Characters mode. This mode is best for logographic text (e.g., Chinese and Japanese). This was suggested by Paul Howarth.
- Very minor cosmetic changes.
- Save button is now only enabled if there are changes.
- An improved help window with slightly more information.
- Subtle bugfix that caused inaccurate highlight positioning in rare cases.
- In addition to Appearance comparisons using highlighting, they can now
also some composition modes to help make subtle differences more
visible. (This was inspired by feedback by Florian Heiderich.)
- Can now control the square size for appearance comparisons. Using very
small squares can help reveal tiny Appearance differences.

Proposal for measuring out-of-time-ordered correlators at finite temperature with coupled spin chains
Information scrambling, which is the spread of local information through a system's many-body degrees of freedom, is an intrinsic feature of many-body dynamics. In quantum systems, the out-of-time-ordered correlator (OTOC) quantifies information scrambling. Motivated by experiments that have measured the OTOC at infinite temperature and a theory proposal to measure the OTOC at finite temperature using the thermofield double state, we describe a protocol to measure the OTOC in a finite temperature spin chain that is realized approximately as one half of the ground state of two moderately-sized coupled spin chains. We consider a spin Hamiltonian with particle-hole symmetry, for which we show that the OTOC can be measured without needing sign-reversal of the Hamiltonian. We describe a protocol to mitigate errors in the estimated OTOC, arising from the finite approximation of the system to the thermofield double state. We show that our protocol is also robust to main sources of decoherence in experiments.


text: The problem of finding the optimal roadway segment configuration for road-based surveillance technologies to estimate route travel times accurately is addressed. This problem is inherently a space discretization problem regardless of which travel time estimation function is used. Its ad hoc solution is the equidistant segment configuration, such as every half mile or every 1 mi. It is shown that the space discretization problem can be expressed as the common clustering problem. The novelty of the proposed approach is the use of preliminary vehicle trajectory data to obtain statistically significant traffic regime at the study route. Clustering of sample space-time trajectory data is proposed as a viable methodology for solving the optimal roadway segment configuration problem.

USCIS Proposes Changes to TPS Employment Authorization Policy
On September 23, 2011 USCIS announced proposed changes in when Employment Authorization Documents (EAD) are issued to Temporary Protected Status (TPS) holders. USCIS proposes to broaden availability of EADs to TPS holders who have had their status withdrawn or denied and are currently appealing the decision to the Administrative Appeals Office (AAO).
During a Stakeholder meeting held September 8, 2011, participants commented that withdrawal of EADs during the appeal process placed a significant financial burden on typically low-skilled laborers and the most vulnerable. Participants suggested economic need should be considered as a factor in extending employment authorization.
Participants also argued that EADs are often the only identification documents held by TPS holder, without which TPS holders can be unable to acquire other documents such as drivers licenses.
Participants also argued that TPS is often withdrawn or denied due to government error. Allowing TPS holders to retain EADs during the appeal process can reduce detrimental effects of such mistakes.
Participants also argued that the revocation of EADs can also result in an unnecessary governmental buden.
USCIS will review the concerns raised and consider the proposal in the formulation of new regulations.

If a pattern asks you to slip a stitch, there are two different ways that you might do that. The first one is to slip as if to knit and the second is to slip as if to purl. It's very easy. If you are going to knit a stitch, you would be inserting your right needle into the left side of the stitch. So to slip a stitch as if to knit means to slip it that way. So you don't knit it at all, you just pass it over to the right needle.
If you were going to purl a stitch, you would be inserting your right needle into the right side of the loop. So to slip a stitch as if to purl, you're going to slip it that way. It's a small thing, but it really does make a difference in how the stitches are mounted on the needle. So here's a slip as if to knit. Here's a slip as if to purl. Slip as if to knit comes from the left side. Slip as if to purl comes from the right side. That's how to slip a stitch.


_TAG_ Caves
The sandy and rocky beaches hold a special place in the heart of the visitor to Pegeia. The caves have a unique beauty, created by marine erosion, and seals are resting and procreating occasionally. Pegeia's sea caves with the unique sculpted rocks, formed in thousands of years by earth and sea, are a unique marvel of natural beauty, impressing all visitors.
Step by step, the visitor can investigate the entire Sea Caves region, with its rock aisles, its coastal formations and caves, as well as look upon the water element. The corrosive activity of the sea has managed to penetrate and 'eat through' the rocks in time, and create an important natural mosaic.
The landscape is of unique beauty, geological and biological interest, while high, rocky beaches have been formed at some points of the bay, sometimes reaching a height of 20 meters.
The dispersed islets make the visitor's gaze wander between the land, the rock and the sea…

People frequently use fluctuating string in AdS black hole (see 1,2,3 etc) to study dynamics of a "free external quark" in quark-gluon-plasma (QGP) at finite temperature. The background black hole geometry induces a black hole in the string world sheet. Many interesting results about the boundary theory can be obtained, at least qualitatively, just studying the Nambu-Goto action.
My question is : Why do people usually choose just one of the transverse spatial directions along which the world sheet can fluctuate? Suppose there is a background magnetic field in addition. Shouldn't one need at least two spatial directions for the world sheet to fluctuate to observe/study its effect on the "quark"?

On November 14, 2006, the South African National Assembly voted 230-41 to approve the Civil Unions Bill, becoming the first African nation to recognize same-sex marriages. The legislation, without reference to gender, recognizes the "voluntary union of two persons, which is solemnized and registered by either a marriage or civil union." It also includes an opt-out clause, which allows officiants to refuse to perform a same-sex ceremony if it conflicts with his or her "conscience, religion and belief." The legislation came in response to a ruling by the Constitutional Court, finding the ban on same-sex marriage unconstitutional.

People who eat spicy foods nearly every day reduce their risk of death by 14 per cent compared with those who consume spicy foods less than once a week. Does it mean that reducing spices, additives, high amine foods, and MSG, as many food sensitive people do, may not be a good thing?
The report, from Harvard University, published in the BMJ in August continues 'Regular spicy food eaters are also less likely to die from cancer, heart, and respiratory diseases than those who eat spicy foods infrequently.' This is a study of the general population in China aged from 30 to 79, so it may have no relevance to the small population that makes up the food sensitive group.
But it does make us think what may the relevance for them? Asian doctors reporting on the incidence of food sensitivity symptoms in Chinese in Australia say they have many more symptoms than their relatives in China.

As part of Alfa Laval's energy efficient solution for cooling tall buildings, gasketed plate heat exchangers serve as pressure interceptors to protect equipment such as chillers and air conditioning units against excessive pressure.
Advantages of plate heat exchangers as pressure breakers
- Compact and only require normal room height, which makes installation easy, even in buildings with limited space.
- Do not cause any vibrations or noise.
- Economical for building owners as the rest of the floor can be rented out without the tenants being disturbed.
The entire chilled water system will be designed for low pressure, for example 10 bar (150 psig). This means cost savings in the chiller as well as in the selection of air handling units and other system equipment. Instead of having many chillers in a building, plate heat exchangers can be placed on several floors as pressure interceptors.
How pressure breaker works
In tall buildings, the static head creates a pressure that may exceed what the chiller condenser or room air conditioners can handle. A plate heat exchanger will then split the circuit in order to keep the pressure at an acceptable level. It is possible to put plate heat exchangers on different levels throughout the building, thus limiting the pressure and the corresponding requirements on, for
example, pumps, piping and valves.
Plate heat exchangers are used as pressure breakers to protect other equipment like chillers and air condition units from excessive pressure. It is a compact, low-noise, no-worries solution.
How to relieve pressure and ensure safety in skyscrapers
Placing gasketed plate heat exchangers on different levels throughout a skyscraper limits the pressure on HVAC piping systems and other equipment. Resulting in consistent cooling on all levels of the building.
The height of efficiency
For maximum energy efficiency, pressure breakers need to perform with a minimum of temperature losses. Alfa Laval gasketed plate heat exchangers ensure superior heat recovery and minimal losses in transferring the cooling media in the complete building – even in extraordinary high constructions. Our heat exchangers are performing this role in the world's 10 tallest buildings.

When you run Perfmon.exe with the Active Directory Diagnostics template to generate a report on a Windows Server 2008-based domain controller, the process may stop responding.
This issue occurs because the Reliability and Performance Monitor (Perfmon.exe) console that is running the TraceRpt.exe tool consumes too much memory and CPU resources during the report generation process. If the Windows Server 2008-based server is really busy and lacks resources, the report generation process will stop responding.
To resolve this issue, copy your files to a different computer that has same server role and that has enough hardware resources. Then, run TraceRpt.exe with the files. To do this, follow these steps:
In the Reliability and Performance Monitor (Perfmon.exe) console, click Data Collector Sets, and then click System.
Right-click Active Directory Diagnostics, and then click Start. The file collection process starts on the Windows Server 2008-based domain controller.
After the report status changes to generating report from collecting data for , copy the files to the second Windows Server 2008-based domain controller.
Note You can find the files at the following location:
Windows Server 2008 Standard, Windows Server 2008 Enterprise, Windows Server 2008 Datacenter, Windows Server 2008 Standard without Hyper-V, Windows Server 2008 for Itanium-Based Systems, Windows Server 2008 Enterprise without Hyper-V, Windows Server 2008 Datacenter without Hyper-V

What is a brain Profile?
It is accepted that all human beings are different and have unique ways of understanding the world around them. This means that our minds do not necessarily function or interpret information the same way. With this said, there are implications for how people can be treated and managed because not everyone is the same. The Neethling Brain Instruments (NBI®) is a highly practical and ground breaking set of instruments and questionnaires that will expose an individual's preferred way of thinking and in so doing aid in harnessing the power and development of whole-brain thinking.

Prayer plant (Maranta leuconeura), a 60-hour time-lapse
Watch more with these video collections:
Native to Brazil, the prayer plant (Maranta leuconeura) is one of around four dozen Maranta species that move in a unique way: By day, its leaves are flat and open, and at night, its leaves raise up, folding like praying hands. This nightly change is called nyctinasty or nyctinastic leaf movement.
There have been many scientific studies about this phenomenon, and lots of time-lapse YouTube videos that capture this movement. This 60 hour timelapse, recorded by Ivan Dub in 2019, reveals just how much the Maranta moves. Does that baby in the photo looks astonished?
Prayer plant (Maranta leuconeura), a 60 hour time-lapse
From genetic basis of the "sleeping leaves" revealed (2012):
Contrary to intuition, plants are capable of moving in response to environmental stimuli. This movement is achieved either through irreversible differential growth or through reversible changes in turgor. An example of differential growth is the growth toward a light source (phototropism) observed in the majority of plant shoots. Tropisms are plant movements induced by directional stimuli, such as light or gravity. In addition, plants can move in response to nondirectional factors, such as humidity or contact. These movements are called nastic responses. Nyctinasty, the proper name for the "sleep movements of leaves" is a well-known example of a nastic response. In this case, plants close up their leaves and petals in response to the onset of darkness. Because it is a rather fast response, it does not involve differential growth but changes in cellular turgor.

TAHLEQUAH — The Cherokee Nation held a ribbon-cutting ceremony at the tribe's headquarters in Tahlequah Tuesday to celebrate the first tribal solar canopy car charging station to be built by a tribe in Oklahoma.
Cherokee Nation's new charging station is located in the main parking lot of the W.W. Keeler Tribal Complex. It is capable of charging up to eight electric vehicles and also provides about 58,000 kilowatt hours of electricity to the tribal complex each year, equivalent to the amount of electricity needed to power three or more homes.
"Embracing solar panels and adding electric vehicles to our fleet is consistent with Cherokee Nation's leadership in clean-energy usage and carbon-footprint reduction," Cherokee Nation Principal Chief Bill John Baker said. "Cherokee Nation is the first tribal government in Oklahoma to build and utilize a solar canopy like this. We have always been good stewards of the land, and this is another example of exceptional natural resource conservation, a legacy established by our ancestors."
Construction costs for the solar canopy totaled around $300,000 through a partnership between Cherokee Nation and the Bureau of Indian Affairs.
The Cherokee Nation purchased its first two 100-percent electric-powered Nissan Leaf compact cars in October. The Leafs can travel about 107 miles on one charge and produce zero emissions.
Francis Renewable Energy of Tulsa was the contractor for the solar canopy charging station.
The solar canopy and addition of electric vehicles to the Cherokee Nation fleet are part of the tribe's recent initiative to reduce carbon emissions.

Research of Reinforce Plan for No. Zero Frame of TB200 Aircraft and Secondary Damage Prediction
The original structure stress state of No. zero frame of TB200 aircraft is analyzed by finite element method. The stress and the reasons of the crack on the frame are determined. The numerical analysis results fit well with the actual damage of the frame, and the finite element analysis model is verified to be reliable. The stress state of the damaged frame structure is analyzed, which shows that the undamaged frame structure must be reinforced. The reinforce plan for the undamaged frame structure is given. The reinforced frame structure is analyzed by finite element method. The stress state and the residual strength of the reinforced frame structure are given. It is showed that the reinforce plan causes an obvious descent of the frame stress. The load is mainly distributed on the reinforcement of the No. zero frame. The residual static strength of the reinforced structure is higher than the original structure. The possible secondary damage position and mode of the reinforced structure are predicted.
