A pulse detonation engine is an unsteady propulsive device in which the combustion chamber is periodically filled with a reactive gas mixture, a detonation is initiated, the detonation propagates through the chamber, and the product gases are exhausted. The high pressures and resultant momentum flux out of the chamber generate thrust.

Quasi-steady thrust levels can be achieved by repeating this cycle at relatively high frequency and/or using more than one combustion chamber operating out of phase.A pulse ....etc

Motherboard, Processor and Memory form the main components of a computer system. The motherboard is the circuit board to which all the other components of the computer connect in some way. The video card, sound card, IDE hard drive, etc. all plug into the motherboard's various slots and connectors. The CPU also plugs into the motherboard via a Socket or a Slot. Motherboard is the main circuit board of a computer. It contains connectors and ports for attaching additional boards and peripheral devices. It has multiple controller chips on the moth ....etc

ABSTRACT
It is reported that millions of people are suffering from some kind of hearing impairment. The number is climbing due to the increasing portion of elderly people in the worldâ„¢s population. While hearing loss is usually caused by permanent mechanical damage to the ear, there is no medicine to reverse it, as surgery offers little help.
Thus the electronic hearing aid or prosthetic are the best known solutions to the patients. Hence a neurofuzzy approach for devices that combine neural networks and fuzzy logic t ....etc

Definition
Over the last decade, the growth of satellite service, the rise of digital cable, and the birth of HDTV have all left their mark on the television landscape. Now, a new delivery method threatens to shake things up even more powerfully. Internet Protocol Television (IPTV) has arrived, and backed by the deep pockets of the telecommunications industry, it's poised to offer more interactivity and bring a hefty dose of competition to the business of selling TV.

IPTV describes a system capable of receiving and displaying a video stream ....etc

Introduction
A data logger (or datalogger) is an electronic instrument that records data over time or in relation to location. Increasingly, but not necessarily, they are based on a digital processor (or computer). They may be small, battery powered and portable and vary between general purpose types for a range of measurement applications to very specific devices for measuring in one environment only.It is common for general purpose types to beprogrammable.
Standardisation of protocols and data formats is growing in the industry and XML is ....etc

The embedded system is a combination of computer hardware, software and, perhaps, additional mechanical parts, designed to perform a specific function. A good example is an automatic washing machine or a microwave oven. Embedded systems need only the basic functionalities of an operating system in real-time environment-a scaled down version of an RTOS. They demand extremely high reliability plus the ability to customize the OS to match an applicationâ„¢s unique requirements. However, commercial RTOSes, while designed to satisfy the reliabil ....etc

Abstract
Dual-quorum replication is a novel data replication algorithm designed to support Internet
edge services. The internet edge service architecture attempts to improve service availability and
latency by allowing clients to access the closely available edge server rather than a cen ....etc

Introduction

Thyristor technology is inherently superior to transistor for blocking voltage values above 2.5kV, plasma distributions equal to those of diodes offering the best trade-off between the on-state and blocking voltages. Until the introduction of newer power switches, the only serious contenders for high-power transportation systems and other applications were the GTO (thyristor), with its cumbersome snubbers, and the IGBT (transistor), with its inherently high losses. Until now, adding the gate turn-off feature has resulted in GTO ....etc
