This paper presents a design method of self-tuning Quantitative Feedback Theory (QFT) by using improved deadbeat control algorithm. QFT is a technique to achieve robust control with pre-defined specifications whereas deadbeat is an algorithm that could bring the output to steady state with minimum step size. Nevertheless, usually there are large peaks in the deadbeat response. By integrating QF...

We propose and experimentally demonstrate a continuous wave (CW) tunable-wavelength fiber laser using self-seeding Fabry-Perot laser diode (FP-LD) without optical amplifier inside gain cavity. By employing a tunable bandpass filter (TBF) and a fiber reflected mirror (FRM) within a gain cavity, the fiber laser can lase a single-longitudinal wavelength due to the self-seeding operation. The propo...

Control of inventory in production and operation systems is very important for better management and utilization of resources. In this paper, the optimal control of a periodic-review inventory system with items deterioration is considered. We are concerned with the problem of determining the production rate that minimizes a certain cost function. We deal with both cases where the deterioration ...

This paper concentrates on the computationally efficient implementation of three classes of complementary IIR filter pairs with tunable crossover frequency. Class I denotes the IIR filter pair implemented as a parallel connection of two all-pass filters, whereas Class II (Class III) stands for the tapped cascaded interconnection of two distinct all-pass filters. We propose new tuning formulae f...

A Texas Instruments TMS320C30 floating point digital signal processor has been used to implement a noise canceler/self-tuning filter for extracting sinusoidal audio signals from broad-band noise. A very significant part of the work is the optimization of the tuner's performance through proper choice of relevant adaptive filter parameters as well as efficient TMS320C30 code design and implementa...

A novel approach to design Tunable Dual-Band Band-Stop filters will be presented in this paper. These filters have a new configuration with a coplanar microstrip line loaded with SteppedImpedance Resonators (SIRs). These can be tuned by using tuning elements such as a tuning diode and ferroelectric capacitor. The Dual-Band Band-Stop Filter (DBBSF) and Dual-Band Band-Pass Filter (DBBPF) have bec...

Simultaneous psychophysical tuning curves were obtained from normal-hearing and hearing-impaired listeners, using probe tones that were either at similar sound pressure levels or at similar sensation levels for the two types of listeners. Tuning curves from the hearing-impaired listeners were flat, erratic, broad, and/or inverted, depending upon the frequency region of the probe tone and the fr...

This paper deals with the proposal of a new topology for a gm-C continuous time filter which allows the adjustment and tuning of its characteristic parameters (ωO and Q) in an independent way (without cross-tuning), thereby extending the Q range of the filter for a particular ωO value. Additionally a comparison of three different Q-tuning algorithms is presented. It is shown that an LMS-based Q...

Traditionally, given two timing constraint sets, their relationship is defined by their timed trace inclusions. This approach only gives a boolean answer to if one set of constraints is contained within the other. In this paper, we first introduce a quantitative measure to describe the closeness or the similarity between two timing constraint sets. We intend to study the satisfaction bounds of ...
