AS increasing numbers of distributed generators (DGs) are deployed, utilities are becoming more concerned that these DGs may be able to support unintentional islands. Unintentional islands can be formed when any utility switching device isolates a portion of the area electric power system (EPS) that contains roughly equal amounts of sources and loads, and they potentially pose safety risks to p...

In the present work, a hybrid approach has been proposed for optimal placement of multiple DGs of multiple types. The analytical approaches may not be appropriate for optimal placements of multiple DGs alone. In this work, hybridization of analytical method and heuristic search for the optimal placement of multiple DGs in power distribution network for reduction of power loss has been proposed....

OBJECTIVES A clinically sensible system of grouping diseases is needed for describing pediatric emergency diagnoses for research and reporting. This project aimed to create an International Classification of Diseases (ICD)-based diagnosis grouping system (DGS) for child emergency department (ED) visits that is 1) clinically sensible with regard to how diagnoses are grouped and 2) comprehensive ...

AIMS To examine whether the learning difficulties seen in a proportion of children with DGS are secondary to cardiac pathology and treatment, or a feature of the DGS phenotype. METHODS Cohort study of all patients with DGS and coexisting cardiac lesions within a region. Ten children with 22q11 deletion were assigned two controls each, matched for age, sex, cardiac lesion, and preoperative hem...

We consider simple Lyapunov-exponent-based conditions under which the response of a system to a chaotic drive is a smooth function of the drive state. We call this differentiable generalized synchronization ~DGS!. When DGS does not hold, we quantify the degree of nondifferentiability using the Hölder exponent. We also discuss the consequences of DGS and give an illustrative numerical example. @...

This paper aims to analyze the effect of application of defected ground structure (DGS) on the resonating properties of microstrip patch antenna. In order to obtain the comparative results a small size DGS has been introduced in the ground plane exactly under the feeding strip of the patch antenna. The representative results obtained from the simulations have revealed that the proposed antenna ...

Diacylglycerol isomers and free acidity were determined for five extra virgin olive oils of different initial acidities by employing a facile (31)P NMR methodology as a function of storage time and storage conditions. The kinetic treatment of the hydrolysis of triacylglycerols (TGs) and the isomerization of 1,2-diacylglycerols (1,2-DGs) to 1,3-diacylglycerols (1,3-DGs) during storage of 18 mont...

In a companion study of the effects of acyl chain unsaturation on a series of model sn-1,2-diacylglycerols (DGs) we showed that individual DGs could adopt one of three energy-minimized conformations depending on the number and location of cis double bonds in the sn-2 chain. Here we show that each of these conformations promotes a distinct type of packing arrangement in a simulated DG monolayer....

In this paper, Direct Search Algorithm is implemented to determine the optimal sizes of Type – I Distributed Generators (DGs) and optimal locations such that maximum possible reduction in real power loss is obtained. Type – I DG injects both active and reactive powers. The algorithm searches for all possible locations in the system for a particular size of DG and places it at the bus which give...

This project is intended to build a microstrip low pass filter with a pass band till 3 GHz at 3 dB cutoff frequency. This project is divided into two stages. In the first stage, a conventional seven pole low pass filter using commensurate length 8 / g λ is designed by converting the value of g1 to g7 into unit elements as well as open circuit stubs. In second stage, a method to design low pass ...
