ISO9001:2000 and TS 16949 have become the major quality system management models in present traditional and Hi-tech industries. The Measurement System Analysis (MSA) Reference Manual, on the other hand, is one of the core tools in ISO/TS 16949. MSA aims to evaluate Gauge Repeatability and Reproducibility (GR&R) where the control, monitoring, and maintenance of the measurement process are requir...

In recent times, interest in renewable energy-based Distributed Generation (DG) is increasing rapidly. These sources are connected to AC bus through inverter interface. During islanded mode, output voltage and frequency of should be properly regulated for stable operation it done by applying control action on inverter. The paper presents a strategy controlling output. It deals with active power...

The recent changes in the structure of power generation towards a distributed generation have motivated the increasing interest in the control of so-called microgrids. Microgrids typically consist of an AC electrical network connecting a set of loads and droop-controlled inverters. While the decentralized and proportional primary droop-control ensures the stabilization and the synchronization o...

The efficiency droop in GaInN/GaN multiple-quantum well MQW light-emitting diodes is investigated. Measurements show that the efficiency droop, occurring under high injection conditions, is unrelated to junction temperature. Furthermore, the photoluminescence output as a function of excitation power shows no droop, indicating that the droop is not related to MQW efficiency but rather to the rec...

A new series of uranium coordination polymers have been hydrothermally synthesized by using 1,4-naphthalene dicarboxylic acid (H2NDC), namely, (H3O)2[(UO2)2(NDC)3]·H2O (1), (H2-bpp)[(UO2)2(NDC)3]·EtOH·5H2O (2), (H2-bpe)2/2[(UO2)2(NDC)3]·EtOH (3), (H2-bpp)[(UO2)2(NDC)3]·5H2O (4), (H2-bpp)[(UO2)(HNDC)(NDC)]2·2H2O (5), and (H2-bpy)[(UO2)(NDC)2] (6) [bpp = 1,3-di(4-pyridyl) propane, bpe = 4,4'-viny...

The objective was to study the effect of a commercially available xylanase (CAX), an experimental xylanase (EX), and EX in combination with protease (EXP) on the degradation of nondigestible carbohydrates (NDC) and apparent ileal digestibility (AID) of nutrients in wheat distillers dried grains with solubles (wDDGS). The control and 3 enzyme diets contained 96% wDDGS supplemented with vitamins,...

Abstract A new power sharing method of a virtual sychronous generator control based inverters is introduced in this paper. Since virtual synchronous generator has virtual inertia and damping properties, it significantly enhances the grid stability. However, its output power considerably affects by the line impedance. Thus, in this paper, the relation between the droop control and the line imped...

The optical properties of [Zn(2)(NDC)(2)(DPNI)](0/-/2-) (NDC = 2,7-naphthalene dicarboxylate, DPNI = N,N'-di(4-pyridyl)-1,4,5,8-naphthalenetetracarboxydiimide), a redox-active metal-organic framework, have been examined using a simple and robust in situ solid state UV-Vis-NIR spectroelectrochemical technique.
