The GCA (Global Cellular Automata) model consists of a collection of cells which change their states synchronously depending on the states of their neighbors like in the classical CA (Cellular Automata) model. In differentiation to the CA model the neighbors are not fixed and local, they are variable and global. The GCA model is applicable to a wide range of parallel algorithms. In this paper a...

The spontaneous generation of near-inertial waves (NIWs) from quasi-geostrophic mesoscale eddies in a stratified fluid is investigated and the process mechanism clarified by numerical modeling theoretical analysis. Mesoscale eddies, as slow balance flows, are inevitably accompanied unbalanced oscillations (NIOs) their long period evolution. A eddy supplies kinetic energy to NIOs through its int...

The present paper studies the use of genetic algorithm to optimize tuning Proportional, Integral and Derivative (PID) controller. Two control criteria were considered, integral time multiplied by absolute error (ITAE), output (ITAY). variant plant tested is a first-order with delay. We aim at real implementation inside digital board, so, previous continuous approach was discretized tested; corr...

This paper introduces two custom blocks for Nios reconfigurable embedded processor implemented on Altera Field Programmable Gate Arrays (FPGAs). When operations like modular multiplication and modular exponentiation of long integers or other complex algebraic functions are performed on a general-purpose processor they usually consume a lot of processor resources and execution times are not sati...

With the advent of fast-growing digital, information, and network technologies and the desire for a more convenient lifestyle in recent years, users have higher security expectations for electronic systems. Additionally, e-Business, ATM, access control, and intelligent cards all require a safe and easy-to-use identification technology. The traditional identification method, user ID plus passwor...

For our project, we designed and implemented a cardiac arrhythmia electrocardiogram (ECG) monitoring system that can adaptively modify and change the components of its processing chain to carry out the best treatment on electrocardiogram signals. We investigated and provided a solution to a fundamental problem in the area of biomedical signal processing: accurate QRS complex detection for varyi...
