In this article, an Improved Frequency Regulation (IFR) for interconnected hybrid power system under a deregulated scenario is proposed. The analyzed test comprises of thermal system, biogas plant, and Distributed Generation (DG). impact the integration Renewable Energy Sources (RES) has been examined by considering DG with solar wind generation. order to make more realistic, appropriate non-li...
This article presents a test based on quadratic form using Type-2 with replacement-censored sample for testing exponentiality against weibull IFR/DFR alternative. The percentile points and powers are simulated. The proposed test is compared with that of Bain and Engelhardt (1986) test. An example based on Type-2 censoring is also discussed.
Mixtures of distributions are usually effectively used for modeling heterogeneity. It is well known that mixtures of DFR distributions are always DFR. On the other hand, mixtures of IFR distributions can decrease, at least in some intervals of time. As IFR distributions often model lifetimes governed by ageing processes, the operation of mixing can dramatically change the pattern of ageing. The...
Pressure-wire technology, most typically fractional flow reserve (FFR), has provided interventional cardiologists with a means of determining the physiological importance of a stenosis during angiography. There has been renewed interest in coronary physiology in the light of guideline recognition, ongoing clinical research and new technologies changing the paradigm of how assessment is performe...
Abstract UF-SiAPP was prepared by modifying ammonium polyphosphate with the urea formaldehyde resin (UF), tetraethylorthosilicate (TEOS), and vinyltriethoxysilane (A-151). Moreover, a new intumescent flame retardant (IFR) used for low density polyethylene (LDPE) obtained mixing tris(2-hydroxyethyl) isocynurate (THEIC). The structure, morphology, mechanical properties of retardants LDPE composit...
Most photophysical studies in the halide perovskite have focused on characteristics of surface. However, photons generated at surface would be absorbed by same material (re-absorption), and photophysics re-absorbed are rarely studied. Herein, we present our recent observation re-emission (photoluminescence after re-absorption, IR) Cs4PbBr6, which is temporally slower than surface-emission (IS)....
Abstract We present and analyze the dataset on international distribution of industrial robots by country, industry, application provided International Federation Robotics (IFR) since 1993. After describing IFR we point out specificities limitations its dataset. explain process data collection, develop a correspondence table between industry classification ISIC rev. 4 classification, clarify ap...
