Biometric is a technological system that utilizations the data about individual to distinguish that individual. This technology store particular information for one of kind organic properties so as to work viably. We can utilize biometric framework at government, organizations and associations for security reason. An airplane terminal checking gadget, a "bio-secret key" framework is a case of a biometric system utilizations the recognizing information for a security result. Be that as it may, we require security for this data and in addition verification of that individual. This novel software based technology help to look at the data of individual is genuine or counterfeit because of that we get last aftereffect of validation. Consequently goal of framework is to enhance well being of biometric acknowledgment system which makes quick, easy to understand and minimal effort using image quality assessment. Here we utilize three application data that are iris, finger print and face recognition. The proposing approach uses general image quality features extracting from single image to distinguish between real and fake sample.
This book contains a research report on one of the most important factor "Wind" affecting the autonomous flying of unmanned aerial vehicles. The current research focuses on current wind estimation methods used in commercial off the shelf autopilot boards. The current algorithms are simulated for robust real life wind conditions for a fixed wing aircraft using Software in The Loop Simulator (SITL) setup at Arizona State University. The different flight paths are simulated for near accurate flight dynamics model. The similar experiments with are performed using Skywalker, remote controlled aircraft. The Skywalker is equipped with Ardupilot Mega 2.6 autopilot board. The SITL simulated mission plan was flown onboard with Skywalker airplane. The results shown that the inability of flying through windy condition due to inaccuracy in wind measurement algorithm currently being used. The research work also suggests some newer techniques for estimation and navigation algorithms.
The use of RC airplane is very useful in various fields in the real world applications such as (military, forest-fire monitoring, search and rescue, harbor patrol, pipeline , spying, entertainments........etc.). The basic idea of our project is to analyze and understanding the technology and communication protocol used in the RC airplanes. The technology means the different aspect of RC Airplanes (aerodynamic control servo motor,...etc.) The transmitter communicates your stick positions, via a radio signal, to the RC airplane. The RC airplane contains a receiver, which decodes this transmission and tells the servos to move a position corresponding to what you commanded on software program. The servos are a cool piece of technology. They rotate to whatever position they are told to go to, and are very strong and very accurate. The computer is connected to the micro controller circuit via serial port and matching circuit this three elements are connected with transmitting circuit which send the signals to the receiver circuit placed on the airplane and connected with the servos and the motor. The user give the input value from interface software on the computer .

Simulation software is based on the process of imitating a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually performing that operation. Simulation software is used widely to design equipment so that the final product will be as close to design specs as possible without expensive in process modification. Simulation software with real-time response is often used in gaming, but it also has important industrial applications. When the penalty for improper operation is costly, such as airplane pilots, nuclear power plant operators, or chemical plant operators, a mock up of the actual control panel is connected to a real-time simulation of the physical response, giving valuable training experience without fear of a disastrous outcome.
This volume contains the proceedings of TAP 2010, the 4th International C- ference on Tests and Proofs held during July 1–2 in M´ alaga, Spain as part of TOOLS Federated Conferences. TAP 2010wasthe fourth event of an ongoingseriesof conferencesdevoted to the convergence of proofs and tests. In the past, proving and testing were seen as very di?erent and even competing techniques. Proving people would say: If correctness is proved, what do we need tests for? Testers, on the other hand, would claim that proving is too limited in applicability and testing is the only truepathtocorrectness. Ofcourse,bothhaveapoint,buttoquoteEdBrinksma from his 2009 keynote at the Dutch Testing Day and Testcom/FATES: “Who would want to ?y in an airplane with software proved correct, but not tested?” Indeed, the true power lies in the combination of both approaches. Today, m- ern test systems rely on techniques deeply rooted in formal proof techniques, and testing techniques make it possible to apply proof techniques where there was no possibility previously. At a time when even mainstream software engineering conferences start f- turing papers with both “testing” and “proving”in their titles, we are clearly on the verge of a new age where testing and proving are not competing but ?nally accepted as complementary techniques. Albeit, we are not quite there yet, and so the TAP conferences aim to provide a forum for researchers working on the converging topics and to raise general awareness of this convergence.
Scholarly Research Paper from the year 2011 in the subject Business economics - Business Management, Corporate Governance, printed single-sided, grade: 1,0, Copenhagen Business School (Institute of Finance), course: Strategic Risk Management, language: English, comment: Es wird ein neues Framework zur Risikoerfassung entwickelt. , abstract: The paper will outline major flaws in Airbus's risk management and thereby identify reasons for the production delay of the Airbus 380. The Airbus A-380 project was launched in 2000 and remains the largest project in the company's history. The Airplane was designed to carry up to 853 passengers and offer 50 per cent more floor surface than any other passenger aircraft. The total cost of development summed up to EUR 12 billion and it was planned to deliver the first aircraft to Singapore Airlines in 2005. In reality the first aircraft was delivered in 2007. The 2 years delay of the delivery of the first Airbus 380 eventually added up to an estimated sum of EUR4.8 billion loss in profit. The reason for this delay was that the pre-assembled wirings produced in Germany failed to fit into the frame when the plane was to assemble in France. This misfit can be attributed to the fact that the German plant used CATIA 4 (CATIA is a computer-aided design software) which was only able to show the plane as a two dimensional model while France used CATIA 5 which displayed the plane in three dimensions.
Do you enjoy writing software, except for the database code? Hibernate:A Developer's Notebook is for you. Database experts may enjoy fiddling with SQL, but you don't have to--the rest of the application is the fun part. And even database experts dread the tedious plumbing and typographical spaghetti needed to put their SQL into a Java program. Hibernate: A Developers Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don't even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. Hibernate: A Developer's Notebook walks you through the ins and outs of using Hibernate, from installation and configuration, to complex associations and composite types. Two chapters explore ways to write sophisticated queries, which you can express either through a pure Java API, or with an SQL-inspired, but object-oriented, query language. Don't let that intimidate you though: one of the biggest surprises in working with Hibernate is that for many of the common real-world application scenarios, you don't need an explicit query at all. If you've needed to add a database backend to your application, don't put it off. It's much more fun than it used to be, and Hibernate: A Developer's Notebook shows you why. Here's what a few reviewers had to say: 'I'm sitting on an airplane after finishing Hibernate: A Developer's Notebook. It's rare to find a book on a new Java technology that you can get through on a domestic flight. That this notebook effectively and succinctly tackles object-relational mapping makes it, and Hibernate, even more impressive. Many books in this category would need to be checked luggage. With this book, you travel first class.' --Mike Clark 'A simple persistence framework deserves a simple book, and this one delivers. The examples are well described and easy to understand, yet sophisticated enough to demonstrate Hibernate in a real-world context. Jim, I'm a new fan.' --Bruce Tate About the new Developer's Notebook Series from O'Reilly: Developer's Notebooks are a new book series covering important new tools for software developers. Developer's Notebooks stress example over explanation and practice over theory. They are about learning by doing; by experimenting with tools and discovering what works. 'All lab, no lecture,' with a thoughtful lab partner to guide the way.
Embedded systems are prevalent in today¿s society and promise to be even more pervasive in the future. Applications vary from airplane jet or car controllers, communication devices like cellular phones to consumer electronics like set-top boxes. The steadily increasing number of functional requirements lead to a complex embedded hardware and software architecture. Often, applications not only have to compute correct results but have to achieve this within a given time period. Timing behavior is an important requirement if the application has to react to signals from the environment. To safely and tightly verify timing behavior is very challenging for today¿s complex embedded designs. Caches are small memories close to the processor and they are needed to increase the processor performance but their influence on execution time is difficult to predict because of their complex behavior. Preemptive scheduling is popular in real-time systems to guarantee short response times and a high processor utilization. An additional cache-related preemption delay has to be considered when several tasks share the same cache and when preemptive task scheduling is used. Cache improvements can be strongly degraded by frequent replacements of cache blocks. There are several approaches to make caches more predictable and efficient. Cache partitioning and cache locking strategies are used to make cache behavior partly orthogonal. These approaches require larger caches and main memories to become effective. However, caches are usually small in embedded systems because of their high cost. While these approaches are certainly a very useful add-on to improve cache predictability and efficiency, they do not solve the problem of cache behavior prediction if all tasks shared the cache. This thesis makes several contributions to instruction and data cache timing behavior. First, we propose a novel schedulability analysis for fixed priority preemptive scheduling to consider timing effects for associative instruction caches at a context switch. The preemption delays are calculated by considering the preempted as well as the preempting task. The proposed schedulability analysis bounds the number of preemptions more tightly by excluding infeasible cache interferences. The analysis is conservative, e.g. determines a safe upper bound of the preemption delay, and has a low time complexity. As a refinement, the cache interference by multiple task preemptions is analyzed. While previous approaches calculate the worst-case preemption point and assume that each preemption takes place at this preemption point, we consider the preemption history in the calculation of the total cost for multiple task preemptions. The advantage is that the bound of the total preemption delay for multiple task preemptions can consider the preemption history. Execution time verification is often used on different levels of the system design. Less precise estimates are acceptable in early design stages while highly accurate ones are necessary for verification of hard real time constraints. Two approaches to bound the preemption delay have been proposed which both use data flow techniques but differ significantly in respect to time-complexity and analysis precision. In this thesis we combine these two approaches in a single scalable precision cache analysis to scale the analysis precision and the time-complexity. In an automotive case study we found out that control intensive applications designed with ASCET-SD and Matlab/Simulink models contain only sequential code without loops. Caches cannot increase the performance for such applications because linear code significantly limits the spacial and temporal locality of memory accesses for which a cache is optimized. Existing timing analyses focus on a single task execution. However, embedded applications are activated very frequently if not regularly. Cache lines from a previous task activation might still be available in the cache and need not be loaded during a subsequent task execution. This effect of multiple task execution can result in a significantly reduced number of cache misses. In this thesis we estimate a conservative bound of the cache contents at the beginning of task activation and consider the effect in instruction
The jet age began in 1939 with the brief hop of a secret German airplane. Seventy years later, the entire world depends upon the jet engine in every sphere - political, military, economic, and social. In Hypersonic Thunder, Walter Boyne weaves an intricate story of how the jet engine changed aeronautics and astronautics, pushing the frontiers of flight forward and permitting humankind to enter the space age. Drawing on his knowledge of the period, Boyne paints a gripping picture of jet aviation from the brilliant supersonic Concorde to the coming challenges of hypersonic flight. Using the fictional Shannons as a vehicle, the author ranges the world of aviation, combining the triumphs and tragedies of great aviation companies with the familiar conflicts of family life. All of the great names of aeronautics and astronautics appear here as they did on the historic scene, including such luminaries as Howard Hughes, Kelly Johnson, Burt Rutan, and Steve Fossett. The book thunders with the clash of combat, ranging from the courageous fights of the Israeli Air Force down through the raid on Libya, Operations Desert Storm and Iraqi Freedom, and, most important the ongoing war on terror. And space is not neglected, as Boyne covers everything from Skylab and the Space Shuttle, with its great achievements and terrible tragedies, to the International Space Station.
