Renewable energy sources (RES) are being increasingly connected in distribution system utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from this grid interfacing inverters when installed in 3-phase 4wire distribution systems. The inverter is controlled to perform as multi-function device by incorporating active power filter func...

The paper describes theoryand research-based principles and design guidelines for handling cognitive load in e-learning environments by adapting instructional methods, and presentation formats to levels of learner prior knowledge in a task domain. The suggested approaches and techniques are based on contemporary knowledge of human cognitive architecture, cognitive load theory, and, most importa...

This paper proposes new data control (best effort rate control) algorithm which changes minimum contention window (CWmin) of best effort traffic with respect to traffic load. By applying new traffic load indication parameter, CWmin of best effort is adaptively controlled. In the result of C++ based network simulation, throughput and drop rate of QoS traffic are guaranteed when proposed algorith...

In this case-controlled study, we tested susceptible genetic variants for Alzheimer's disease (AD) in CR1, CLU and PICALM from Genome Wide Association studies (GWAS) in southern Chinese population. 812 participants consisting of 462 late-onset Alzheimer's disease (LOAD) patients and 350 non-demented controls were recruited. We found by multivariate logistic regression analysis, that single nucl...

In this case-controlled study, we tested susceptible genetic variants for Alzheimer's disease (AD) in CR1, CLU and PICALM from genome-wide association studies (GWAS) in a southern Chinese population. Eight hundred twelve participants consisting of 462 late-onset Alzheimer's disease (LOAD) patients and 350 nondemented control subjects were recruited. We found by multivariate logistic regression ...

The main objective of this paper is to construct a distributed environment through which the economic load dispatch solutions of multi-area power systems can be monitored and controlled. A single-server/multi-client architecture which enables the neighboring power systems to access the remote economic load dispatch server (ELD) at any time with their respective data and to get the economic load...

Demand response is a key mechanism for accommodating renewable power in the electric grid. Models of loads in demand response programs are typically assumed to be known a priori, leaving the load aggregator the task of choosing the best command. However, accurate load models are often hard to obtain. To address this problem, we propose an online learning algorithm that performs demand response ...

This paper describes the mathematical modelling of selfexcited induction generators (SEIGs) with are improved electronic load controller (IELC) for microhydel applications supplying variety of loads. In small hydro plants, governor unit of turbine can be eliminated using IELC, which is simple and cost effective. The improved electronic load controller is a combination of a three-phase insulated...

We investigated the issue of whether or not the CNS makes use of an internal model of the motor apparatus in planning and controlling arm movements. In particular, we tested the ability of subjects to predict different hand-held loads by examining grip force adjustments used to stabilize the load in the hand during arm movements. Subjects grasped a manipulandum using a precision grip with the t...

power system blackouts have become a serious problem for electric utilities especially in recent years. different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. to counteract each form of system instability, special algorithms have been designed in the protection system, e.g. under frequency load shedding (ufls) and under vol...
