We present a general framework for the control of direct current (DC) microgrid with star topology (a common DC bus) consisting renewable sources energy, loads, and storage devices connected via step-up step-down DC/DC converters. The objective is guaranteeing voltage stability in while delivering power to loads extracting energy efficiently from sources. To verify grid regulation among number ...

Distributed dynamic event-triggered control (ETC) method is proposed to solve the stochastic and intermittent problem caused by distributed renewable energy generation unit (DG) in microgrid (MG). It aims at reducing communication cost while achieving proportional current sharing among DGs. Firstly, state space function model of MG system established, considering unknown disturbance DGs uncerta...

The Role of Personal, Organizational, and Technological Factors in Predicting Teachers’ Beliefs about Knowledge Sharing M. Bohlool R. Hosseyngholizaadeh, Ph.D. M. Karami, Ph.D. To explore the role of personal, organizational, and technological factors in predicting teachers’ beliefs about knowledge sharing, a sample of 173 Rashtkhaaree teachers was randomly sele...

The present paper aimed at developing an approach based on Fuzzy Inference System (FIS) for measuring of knowledge sharing in the organization. In recent years there has been increasing interest in the knowledge sharing by experts and managers in the world, according to increasing importance of knowledge as the key source of competitive advantage, organizations have made serious effort to find ...

Although there have been many recent calls for increased data sharing, the majority of environmental scientists do not make their individual data sets publicly available in online repositories. Current data-sharing conversations are focused on overcoming the technological challenges associated with data sharing and the lack of rewards and incentives for individuals to share data. We argue that ...

A New Static Var Generator (SVG), using cascaded full-bridge inverters (FBI) with binary output levels and the parallel connections of two cascaded inverters by means of current sharing reactor in each phases is introduced. The new M-level inverter, where M is 2n+2 - 3, consists of only 2n single-phase full bridges for each phases. The proposed technique not only increases the current capacity ...

Dietary flavonoids show beneficial effects in the prevention of chronic diseases. However, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. In the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (BSA) were investigated by fluorescence spectroscopy. The binding affinities of t...

conclusions phoma glomerata pg41 strain sharing natural substrate with toxigenic a. flavus secretes metabolites possessing a significant aflatoxin-degrading activity. the activity is associated mainly with a protein-enriched high-molecular-weight fraction of extracellular metabolites and appears to be of enzymatic origin. results the afb1-degrading activity of protein-enriched fractions, isolat...

the main purpose of this study was to investigate factors influencing knowledge sharing among the personnel of agricultural extension and education organization in the iranian ministry of jihad-e agriculture. a survey method was employed for the study, and 110 personnel randomly selected as a sample out of 140 who were busy working in the organization. data was collected through a questionn...

In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...
