This paper focuses on Hybrid Energy Storage Systems (HESS), consisting of a combination of batteries and Electric Double Layer Capacitors (EDLC), for electric urban busses. The aim of the paper is to develop a methodology to determine the hybridization percentage that allows the electric bus to work with the highest efficiency while reducing battery aging, depending on the chosen topology, cont...

This paper addresses the problem of scheduling real-time data transactions on the bus of multicore processors. The problem is challenging because the bus allows multiple degrees of transaction concurrency. The number of concurrency degrees depends on how the transactions are routed on the bus. We propose an practical abstraction for the scheduling problem together with two scheduling algorithms...

In today’s power industry, a compact and highly efficient converter is the main component for server applications. The objective of this paper to propose totem-pole factor correction (PFC) with DC-link voltage control strategies data center Gallium Nitride High Electron Mobility Transistors (GaN HEMTs) are also used increase density conversion efficiency without reverse recovery loss. With deri...

This paper deals with a control strategy used for designing energy management systems within average-power electric vehicles. The power supply system is composed of three sources, namely a fuel cell, a battery and an ultracapacitor – specialized within distinct frequency ranges – which must be coordinated in order to satisfy power demand of the vehicle’s electrical motor. The three sources with...

This paper proposes a method for the optimal placement of phasor measurement units (PMUs) complete observability power system based on degree neighbourhood vertices. A three-stage algorithm is used to determine minimum number PMUs needed make observable. The key objective proposed methodology minimize total completely observe network and thereby installation cost. In addition, technique also fo...

We present an agent-based model of a public bus where some passengers board and exit at every stop. Agents are the passengers characterized by their ethnicity, age group and cultural backgrounds and respective preferences for seats in the bus. Different scenarios are set up whereby the bus moves in various parts of the city, which maybe segregated residentially, university campuses, and areas o...

The mass usage of traditional fossil energy has adversely affected the environment on a global scale, such as environmental pollution and greenhouse effect. Meanwhile, there has been a growing demand for energy with the development of society. Since traditional fossil energy is not renewable, it is faced with the problem of energy shortage. Solar energy and hydrogen energy are promising, and ph...

CAN bus systems are used in many industrial control applications, particularly automotive. Due to growing system and functional requirements, the low capacity of the CAN bus and usually strict conditions under which it is used in realtime applications, applicability of CAN bus is severely limited. The paper presents an approach for achieving high utilization and breathes new life to CAN bus bas...

The paper introduces a mechanism to implement distributed scheduling for CAN-bus resource in order to meet the requirements of a dynamic distributed real-time system. The key issues considered here, are multicasting, distinguishing between hard real-time, soft real-time, and non real-time constraints, achieving high resource utilization for CAN-bus, and supporting dynamic hard real-time computi...

The common dc-bus concept has become an attractive solution for future aircraft electrical power systems. This article considers the case where a battery connected dc–dc converter and permanent magnet generator ac–dc are supplying dc bus. Applying proper modulation scheme converters, suppression of first-band harmonics ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink...
