Petri Net based Multi-Elevator System with Multi-Agent Environment

Автор:

I’m trying to build bridges between mathematics and practical subjects like information technology and engineering. A Petri nets (PNs) are a graphical and mathematical tool that are used for describing and studying information processing systems that are characterized as being concurrent, asynchronous, distributed, parallel, non-deterministic and/or stochastic. As a graphical tool, Petri nets can be used as a visual-communication aid similar to flow charts, block diagrams and networks. Tokens are used in these nets to simulate the dynamic and concurrent states of systems. As a mathematical tool, it is possible to set up state equations, algebraic equations and other mathematical models governing the behavior of systems. Since Petri nets are a formal methods’ designing and modeling technique, so they are used to model complex systems as mathematical entities. By building a mathematically rigorous model of a complex system, it is possible to verify the system’s properties in a more thorough fashion than empirical testing.

Killzone: Ascendancy

Автор:

There is no poetry or romance in war, it is brutal and ugly and terrifying and it turns men into animals — shrieking, screaming and running while destroying all in their path. It is survival’ Visari, the vicious Helghast dictator, is vanquished, lying dead at the feet of ISA forces soldiers Sev and Rico. Yet the battle is far from over. Visari’s death has wreaked havoc in the Helghast Empire, leaving a legacy of destruction. His last act of violence — a nuclear bomb — has decimated the Special Forces. Sev and Rico must complete their mission alone. They will fight to the death to keep the ruthless Helghast troops at bay. This title is based on Sony’s bestselling game Killzone 3.

Implementing real-time step detection algorithm in EyesWeb environment

Implementing real-time step detection algorithm in EyesWeb environment

Автор:

Many methods are used for measuring and defining the presence of Parkinson’s disease. One important aspect of the disease is gait disturbance, which can be discovered in the early stages of the disease. This disturbance can be measured using three dimensional accelerometers, which are present in the Shimmer device. These devices are light weighted wireless sensor nodes which can be easily mounted on the patient’s limbs. Data captured by the device can be streamed to a computer for real-time processing. The Matlab algorithms for step detection are converted to C++ code so they can be used in the EyesWeb environment. Whereas Matlab code can only serve post-processing, the Shimmer’s Bluetooth datastream can now be processed in real-time, since the EyesWeb environment supports real-time execution. Hence the Visual Studio environment is needed to design the algorithms into C++ based EyesWeb blocks. This real-time detection algorithm can be applied easily in small and inexpensive lab environments to calculate and obtain the Parkinson’s disease severity parameters. Hereby conclusions can be made to prevent the progress of the disease and to treat Parkinson’s disorder in early stages.

Principles of Accounting with Annual Report, Peachtree Complete Accounting

Автор:

This text helps students hit the road with a practical set of tools, and the confidence they need to use those tools effectively in making business decisions. The goal is to introduce a new Principles of Accounting text that better reflects a more conceptual and decision-making approach to the material. The authors have taken a new «macro- to micro-» approach to the Principles of Accounting course by starting with a discussion of real financial statements first, rather than starting with the Accounting Cycle (although the Accounting Cycle is thoroughly covered in Chapters 3 and 4). The objective is to establish how a financial statement communicates the financing, investing, and operating activities of a business to users of accounting information.They motivate students by grounding the discussion in the real world, showing them the relevance of the topics covered to their future career.

Непрерывная интеграция. Улучшение качества программного обеспечения и снижение риска

Автор: Поль М. Дюваль, Стивен Матиас и Эндрю Гловер

В этой книге рассматриваются некоторые из наиболее типичных процессов разработки программного обеспечения: компиляция кода, определение данных и манипулирование ими в базе данных; осуществление проверки, просмотр кода и в конечном итоге развертывание программного обеспечения. Но главное, в ней описано, как непрерывная интеграция способна снизить риски, которые подстерегают при создании приложений. В системе непрерывной интеграции большинство этих процессов автоматизировано, и они запускаются после каждого изменения разрабатываемого программного обеспечения. В книге обсуждаются аспекты автоматизации непрерывной интеграции, большинство предоставляемых ей преимуществ в области повторяемых и склонных к ошибкам процессов. Ныне существует множество великолепных инструментальных средств, поддерживающих непрерывную интеграцию как автоматизированный процесс, использующий сервер CI для автоматизации действий. Тем не менее ручной подход к интеграции (при автоматизированной компиляции) вполне может хорошо сработать.

Proposal for New Key Agreement Protocols

Proposal for New Key Agreement Protocols

Автор:

Since Diffie and Hellman proposed the concept of key agreement protocols (KAP) and public key cryptosystems (PKC) in 1976, various KAP and PKC were proposed. The typical examples of KAP and PKC are almost based on the factoring problem of large integers, the discrete logarithm problem over finite fields and the elliptic curve discrete logarithm problem. It is said that these problems are efficiently solved in a polynomial time by quantum computers. This book presents some KAP that are the fundamental cryptographic primitives with enciphering and digital signature for the secure communication. The main issue of this book is the proposal of three new KAP over the non-commutative ring. I attached a simple numerical example of KAP for reader to understand the procedure of making common keys. Three proposed KAP are based on the computational difficulty for solving the multivariate algebraic equations of high degree to be one of NP problems. To break these KAP we probably need to solve the multivariate algebraic equations of high degree. Then proposed KAP seem to be immune from the attacks by quantum computers. This book is written for graduate students to active researchers.

Application of Data Mining to Predict the Status of PreART Patient

Автор:

In Ethiopia, there are many people who live with HIV and started ART. There is also large amount of data on HIV patients and ART medications. The objective of this research is to predict Pre-ART patient status by applying DM techniques using CD4 count that helps the organization to better patient management, decision making, planning and better manage the disease. Business understanding and data preparation is conducted to know what the business indeed and what type of data the business process use. Besides data preprocessing is applied to prepare good quality datasets for experimentation. Guiding the overall knowledge discovery process CRISP-DM methodology was employed. Experimentation with neural network and J48 algorithm were implemented to build classifier model. J48 model is built with 10-fold cross validation testing technique with minNumObj=25 and ConfidenceFactors=0.25 and results the highest scores of 75.832%. Due to the quality of the data the maximum result of 75.832% is achieved. The researcher believed that the center has to strongly work on data recording, organization and management.
