Voice-over-IP is a growing technology. Companies are beginning to consider commercial investments in these services. Will it be able to provide the quality of service necessary to satisfy customers? If not what will need to be done to remedy the situation.

This work is concerned with numerical methods for controlled regime-switching diffusions, and regime-switching jump diffusions. Numerical procedures based on Markov chain approximation techniques are developed. Convergence of the algorithms is derived by means of weak convergence methods. In addition, examples are also provided for demonstration purpose. 2006 Elsevier Ltd. All rights reserved.

Methods data collection using way listening and speaking engagement. Data techniques recording techniques, note library interview techniques. Based on analysis, it can be concluded several things. Several special features were...

By the virtue of its highly nonlinear magnetic characteristics, Switched Reluctance Machine (SRM) poses a formidable challenge for digital current regulators operating at fixed switching frequency. Very fast tracking performance demanded by dynamic reference profiles often surpass conventional limits on closed-loop bandwidth posed finite sampling The non-linear nature matched disturbance to be ...

One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...
