This paper deals with the designing of the forward adaptive μ-law companding quantizer whose levels are coded with the Golomb-Rice code. The designing is performed for measurement signals with the Gaussian distribution and applied for the speech signal. The model satisfies the G. 712 standard and achieves the decreasing of the bit-rate for 1.34 bps (bits per sample) compared to the G. 711 stand...

This paper suggests a method for designing PSS to damp multi-machine power system oscillations.  The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

XML itself does not support hypermedia, but the XLink standard has been defined to make XML usable for hypermedia. One of XLinks most interesting features is its support for external links and linkbases, which makes it possible to create links between resources without having to change the resources. In order to use these links, user agents must access linkbases and query them for relevant link...

In Self-designing clinical trials, confidence intervals are derived for the difference and the ratio of normal means, where the results of the independent study stages are combined using the weighted inverse normal method. The confidence intervals always hold the predefined nominal confidence level. During the course of the Self-designing trial, the sample sizes as well as the number of study s...

the purpose of this study was to evaluate the rate of using standards of designing electronic courses in educational contents of state-virtual universities in iran. the method of the study was a descriptive-survey one. the statistical population was the educational content of electronic courses in state-virtual universities such as university of science and technology, and shiraz university. da...

In this article we propose the perspective of relationship as a conceptual approach to discipline sound design. Based on literature reviews and case studies, state that making design means designing relationships, even before sounds, include expression in current definitions discipline. Moreover, observe practices can be inscribed more than one relational perspective, thus widening scope possib...

Planning robotic missions in environments shared by humans involves designing controllers that are reactive to the environment yet able to fulfill a complex high-level task. This paper introduces a new method for designing low-level controllers for nonlinear robotic platforms based on a discrete-state high-level controller encoding the behaviors of a reactive task specification. We build our me...
