this paper presents as a brief introduction , the basic principles of matrix algebra for an alysing the power system problems with digital computers. the material contained in the text are as follows: primitive network, topology of electrical network, transformation of coordinates, bus admittance and bus impedance matrix.

Bus-based system-on-a-chip (SoC) design has become the major integrated methodology for shortening SoC design time. The main challenge is how to verify on-chip bus protocols efficiently. Although traditional simulation-based bus protocol monitors can check whether bus signals obey bus protocol or not. They are still lack of an efficient bus protocols verification environment such as FPGA-level ...

DICE is a shared-bus multiprocessor based on a distributed shared-memory architecture, known as Cache-Only Memory Architecture (COMA). Unlike previous COMA proposals for large-scale multiprocessing, DICE utilizes the COMA to effectively decrease the gap between modern high-performance microprocessors and the bus. As microprocessors become faster and demand more bandwidth, the already limited sc...

In major cities public buses serve as a main source for public transportation System. It has been found that much research work has been carried out in this field using GPS-GSM technology to detect the bus and GPS technology to extract the location of the bus. Taking these aspects into consideration we have proposed a Bus Tracing System with Arrival Time Prediction, by which the commuters can g...

ABSTRACT Bus communication system was established mainly using Sim Events module in the software of Matlab/Simulink. Performance indexes of bus system, which embraces worst-case response time of messages and bus load, were separately gained by theoretical calculation, experiments in Matlab and CANoe. The calculation and experiment results were compared sufficiently, and it concludes that bus sy...

This paper proposes an approach to evaluate the impact of bus network changes on bus travel time. The approach relies on data obtained from buses equipped with GPS devices, which act as mobile traffic sensors. It involves three main steps: (1) analysis of the bus network to determine which road segments are frequently traversed by buses; (2) computation of bus travel time patterns by segment; (...

Accurate and real-time travel time information for buses can help passengers better plan their trips and minimize waiting times. A dynamic travel time prediction model for buses addressing the cases on road with multiple bus routes is proposed in this paper, based on support vector machines (SVMs) and Kalman filtering-based algorithm. In the proposed model, the well-trained SVM model predicts t...

Route bus system is one of fundamental transportation device for aged people and students, and has an important role in every province. However, passengers decrease year by year, therefore the authors have developed the system called ”Bus-Net” as a web application to sustain the public transport. But there are two problems in Bus-Net. One is the user interface that does not consider the variety...
