Among the most significant technological developments of the past 20 years are computer-based systems (CBSs), where functional, performance, and reliability requirements demand the tight integration of physical processes and information processing. Because complex component interactions exist in these systems, we must construct the software and its associated hardware such that they can evolve ...

Poka Yoke is a method of quality management which is related to prevent faults from arising during production processes. It deals with “fail-safing” or “mistake-proofing”. The Poka-yoke concept was generated and developed by Shigeo Shingo for the Toyota Production System. Poka Yoke is used in many fields, especially in monitoring production processes. In many cases, identifying faults in a prod...

Power-efficient wavelength conversion over wide input and output wavelength span is reported using a novel, monolithically integrated SOA-MMI-MZI wavelength converter and SGDBR widelytunable laser.

Modular multilevel converters are widely used in power systems because of their significant advantages. In this paper, a dynamic mathematical model is established by analyzing the topology, operating principle and switching function modular converter, so as to construct an inner outer loop decoupling controller dq coordinates. The carrier phase-shift pulse-width modulation selected control sub-...

This paper presents the design and implementation of a power converter for an autonomous wind induction generator (IG) feeding an isolated load through the PWM-based novel soft-switching interleaved boost converter. The output voltage and frequency of the wind IG is inherently variable due to random fluctuation of wind-speed variation. The interleaved boost converter composed of two shunted ele...

A low-power low-cost highly efficient maximum power point tracker (MPPT) to be integrated into a photovoltaic (PV) panel is proposed. This can result in a 25% energy enhancement compared to a standard photovoltaic panel, while performing functions like battery voltage regulation and matching of the PV array with the load. Instead of using an externally connected MPPT, it is proposed to use an i...

The paper presents the preliminary results on development of an integrated stripline-based microwave-microfluidic module. measurements were performed in a frequency range from 300 MHz up to 12 GHz, with microchannel filled three different test fluids—deionized water, ethanol-water solution and pure ethanol. Due higher-than-expected losses transmittance, selected module was examined use cross-se...
