The Seeheim Model of humancomputer interaction partitions an interactive application into a user-interface, a dialogue controller and the application itself. One of the formal techniques of implementing the dialogue controller is based on context-free grammars and automata. In this work, we modify an off-the-shelf compiler generator (YACC) to generate the dialogue controller. The dialogue contr...

We present a complete design of a multi channels PID controller for Thermoelectric Cooler (TEC) using a pulse width modulation (PWM) technique implemented by a dedicated programmable logic device (PLD) programmed by VHDL. The PID control loop is implemented by software written by National Instrument Lab-Windows CVI. Due to the fact that the implementation is by a VHDL and PLD the design is modu...

Both the increasing usage of intratympanic medication to the inner ear through the round window and the popularity of cochlear implantation have raised interest in the anatomy of the round-window niche (RWN). The objectives of this study were to measure the RWN and to standardize a computed tomographic projection for measuring it. We included patients of all ages who underwent computed tomograp...

This paper presents design and implements the T-DOF PI controller design for a speed control of induction motor. The voltage source inverter type space vector pulse width modulation technique is used the drive system. This scheme leads to be able to adjust the speed of the motor by control the frequency and amplitude of the input voltage. The ratio of input stator voltage to frequency should be...

This paper deals with the recently proposed detector of chaotic states in nonlinear oscillatory circuits [1]. Detector is based on time-frequency representations of signals generated by oscillators. It can be realized by using cross-terms free (or reduced) representations such as the short-time Fourier transform (STFT). It has been noticed that its accuracy substantially depends on the applied ...

A method for the design of ultraspherical window functions that achieves prescribed spectral characteristics is proposed. The method comprises a collection of techniques that can be used to determine the three independent parameters of the ultraspherical window such that a specified ripple ratio and main-lobe width or null-to-null width along with a user-defined side-lobe pattern can be achieve...
