High Speed Downlink Packet Access (HSDPA) – A Means of Increasing Downlink Capacity in WCDMA Cellular Networks
Abstract:
The increasing demand for capacity in order to provide high data rate multimedia services in wireless environments necessitates enhanced radio transmission techniques and network protocol functionality. Such techniques have to be added to already existing mobile cellular networks, e.g. as provided by EDGE. For 3rd generation UMTS networks based on WCDMA, the High Speed Downlink Packet Access (HSDPA) is bein ....etc

EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD


EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD


METHODOLOGY

The concept of increasing the fuel efficiency of a petrol engine in this project, is to pre-heat the intake air which is flowing through the carburetor. The humidity in the atmospheric air affects the petrol vapourisation in the carburettor. Therefore, by pre-heating the inlet air to the carburettor for a considerable amount, the vapourisation can be ease and ....etc

INCREASING PENETRATION OF DISTRIBUTED
GENERATION IN EXISTING DISTRIBUTION
NETWORKS USING COORDINATED VOLTAGE

ABSTRACT
Connections of distributed generation (DG) to weak distribution networks often
experience voltage rise problems. The voltage rise caused by DG can be reduced
with passive methods such as increasing the conductor size but this can be quite
expensive. Active management of distribution networks can allow connection of
more DG into existing distribution networks and, consequently, reduce the connec-
tion ....etc

Automotive thermoelectric generator
An automotive thermoelectric generator (ATEG) is a device that utilizes the Seebeck effect in order to recover lost heat from an internal combustion engine powered vehicle, and generate electricity with it. A typical ATEG consists of four main elements: A hot-side heat exchanger, a cold-side heat exchanger, thermoelectric materials, and compression assembly system. ATEGs can be classified according to their hot-side heat exchanger to exhaust-based ATEGs and coolant-based ATEGs. The ....etc

INTRODUCTION
A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is a useful and cheap medium for transferring heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to ....etc
