In order to solve the problem of low voltage caused by unbalanced load in distribution network, a transformer loss intelligent prediction model under is proposed. Firstly, mathematical with an established. The zero-sequence impedance and neutral line current are calculated using Chaos Game Optimization algorithm (CGO), correctness proved actual data. Then, correlation among network input variab...

The Long Term Evolution-Advanced (LTE-A) heterogeneous network (HetNet), which can increase the capacity of LTE-A, is composed of high power macrocells and low power picocells. However, unbalanced loading between macro and pico cells and inter-cell interference problems are two major performance bottlenecks in LTE-A heterogeneous networks (HetNets). We propose Self-Organizing Network (SON)-base...

In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

OBJECTIVE To compare the load to ultimate failure, load to a 2 mm gap, mode of failure, and gap at failure (mm) of the Teno Fix(®) (TF) to the 3-loop pulley (3LP) for repair of equine tendon lacerations. The use of 4TF devices versus 5TF devices on load to ultimate failure and load to a 2 mm gap was also compared. STUDY DESIGN Ex vivo biomechanical study; unbalanced incomplete block (horse) d...

This paper presents the simulation of Shunt Active Power filter by using two different control schemes, indirect current control technique and ANN control technique. These two controle techniques are working under both balanced and unbalanced three phase voltage source conditions and it is feeding to a adjustable speed drive the torque speed characteristics of a motor is presented. Indirect cur...

The Multi Carrier Code Division Multiple Access (MC-CDMA) system with time division duplex mode, adopting unbalanced slot allocation between uplink and downlink, is a good solution for asymmetric multimedia traffic. A centralized common slot allocation to minimize inter-cell interference is not feasible as neighboring cells may carry different rates of traffic load. In this paper, we investigat...

Delay Tolerant Network (DTN) is one kind of emerging networks characterized by long delay and intermittent connectivity. Traditional ad hoc routing protocols are inapplicable or perform poorly in DTNs because nodes are seldom fully connected. In recent years, many routing protocols (especially social-based routing) are proposed to improve the delivery ratio in DTNs, but most of them do not cons...

This paper presents a novel configuration of separate zigzag transformers based 18-pulse AC –DC converter for improving the ripple factor & isolation of three phase uncontrolled rectifier, this approach eliminates the complexity required to design a complicated auto transformers or isolated multi winding transformer as used with other systems. The paper also presents the comparison among 12 pul...
