In this paper. a VLSI architecture employing router-level redundancy. referred to as a quad-spare mesh. is proposed for fault tolerant NoC designs. This design deals with the problem that a faulty router breaks the communication between healthy PEs. The proposed design significantly improves a system’s reliability and its mean time …

Power loss due to the Joule effect in a distribution system can be very large. where the loss on TRs can account for a consid-erable portion. This paper proposes a method for optimal placement of capacitor banks to TRs for power loss reduction in radial distribution systems. The problem is …

Switching transients associated with circuit breakers have been observed for many years. Recently this phenomenon has been attributed to a significant number of transformer failures involving primary circuit breaker switching. These transformer failures had common contributing factors such as 1) primary vacuum or SF-6 breaker. 2) short cable or bus …

We study the problem of tracking a moving target using navigated mobile sensors in wireless sensor networks. With unknown target and mobile sensor locations. we need to estimate the locations of the target and the mobile sensors first. Based on a more general TOA measurement model. convex optimization algorithms through …

A simplified and effective approach of PMU placement for large-scale distribution systems is presented in this paper. The proposed algorithm finds an optimal solution to placement problem by decomposition of network into two sub-networks. Since the problem size is reduced due to splitting into two stages. this decomposition reduces the …

The paper introduced a novel. 1 phase stator Ferrite PM small motor &amp. drive in order to reduce fabrication and initial motor cost and simplify the inverter control The novel motor has only two stator coils where the PM flux switches polarity in a doubly salient topology with 4 rotor …

In this paper. a Smart Parking System (SPS) based on the integration of Ultra-High Frequency (UHF) Radio Frequency Identification (RFID) and IEEE 802.15.4 Wireless Sensor Network (WSN) technologies is presented. The system is able to collect information about the occupancy state of parking spaces. and to direct drivers to the …

Using a criterion based on the damping ratio. an optimization algorithm was successfully applied to establish the optimal coordination between PSSs and UPFC-based stabilizer using Genetic Algorithm (GA). A multi-objective function was utilized to formulate the problem. whose solution aims to maximize the damping ratios of the electromechanical modes using …

Optimal capacity of a large-scale BESS integrated with a grid-connected wind farm has been determined. It has been shown that the optimal size of all the batteries of the BESS decreases as the number of batteries increases. Furthermore. the optimal size of all the batteries of the BESS tends to …

Based on the FEM. this paper sets out a new mathematical model for calculation and analysis of the HTS LIM. which considers the current characteristics and the magnetic flux pinning phenomenon of the superconductor. The magnetic flux density distributions and the performance as thrust. vertical force. eddy-current loss. efficiency. and …
