in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...

This paper has developed a novel multiobjective function for optimal sizing and sitting ofDistributed Generation (DG) units and capacitor banks in simultaneous mode to improve reliabilityand reduce energy losses. The proposed function consists of four objectives: Cost of Energy NotSupplied (CENS), System Average Interruption Duration Index (SAIDI), costs of energy loss andinvestment. A novel st...

This paper focused on the development of capacitor voltage balancing methods in a flying capacitor multilevel inverter (FCMLI) fed induction motor drive. For improving the performance of flying capacitor multilevel inverter, a switching pattern selection scheme is implemented. The proposed method has been designed a seven-level flying capacitor multilevel inverter by using sinusoidal pulse widt...

This paper shows that a highly deformable capacitor made of a soft dielectric and two conformal electrodes can switch between two states discontinuously, by a first-order transition, as the total charge varies gradually. When the total charge is small, it spreads evenly over the area of the capacitor, and the capacitor deforms homogeneously. When the total charge is large, it localizes in a sma...

The problem of capacitor allocation for loss reduction in electric distribution systems has been extensively researched over the past several decades. This paper describes the evolution of the research and provides an evaluation of the practicality and accuracy of the capacitor placement algorithms in the literature. The intent of this paper is not to provide a complete survey of all the litera...

This paper focuses on the development of capacitor voltage balancing methods in a flying capacitor multilevel inverter (FCMLI) fed induction motor drive. For improve the performance of flying capacitor multilevel inverter to implement a switching pattern selection scheme. This reduces capacitor voltage fluctuation without using voltage feedback and RLC Filter circuits connected in parallel with...

background: meiotic genes are very important candidates for genes contributing to female and male infertility. mammalian mutl homologues have dual roles in dna mismatch repair (mmr) after replication errors and meiotic reciprocal recombination. the mutl homologs, mlh1 and mlh3 , are crucial for meiotic reciprocal recombination and human fertility. in this study the functional polymorphisms of m...

BACKGROUND Phase-2 voltage and maximum pulse width are dependent on phase-1 pulse characteristics in a single-capacitor biphasic waveform. The use of 2 separate output capacitors avoids these limitations and may allow waveforms with lower defibrillation thresholds. A previous report also suggested that the optimal tilt may be >70%. This study was designed to determine an optimal biphasic wavefo...
