Abstract There are two main approaches, static and dynamic, to broadcast algorithms in wireless ad hoc networks. In the static approach, local algorithms determine the status (forwarding/nonforwarding) of each node proactively based on local topology information and a globally known priority function. In this paper, we first show that local broadcast algorithms based on the static approach cannot achieve a good approximation factor to the optimum solution (an NP-hard problem). However, we show that a constant approximation factor is achievable ....etc

Pile driving at large construction sites produces formidable noise. Marine pile driving similarly can produce high sound pressures underwater but these can be lethal to fish and can harass marine mammals, including those protected by federal law. This problem has contributed to costly construction delays on major bridge projects. To protect marine life, engineers have designed air bubble curtains to reduce underwater sounds. Air provides an effective barrier to sound propagating through water, because of the difference in density between air ....etc

Abstract:
This paper presents a new methodology for enhancing the distribution system performance by minimizing both technical and non technical losses. Most of the utility companies in developing countries are victims of major revenue losses due to technical and non technical energy losses. The non technical losses are like electricity theft, unauthorized connections, irregular billing and the technical losses are I2R power losses. These losses affect the quality of supply in terms of voltage magnitude, and more tariffs imposed on genuine cus ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same speed.

Abstract Employees are increasingly participating in business
processes using mobile devices. Often, this is supported
by a mobile web application, which accesses various web
services in the back-end. The high latency of the mobile
network (e.g., EDGE) is perceived by the user each time
a web service is called, in addition to the time needed to
invoke the service itself. This high latency may lead to low
usability, low acceptance rate, and finally compromises the
overall process quality. To reduce the latency perceived by the
user, we ....etc

Why a global UNDP Report on Disaster Risk
Economic losses and the numbers affected by disasters continue to increase.
Disaster loss is challenging the achievement of the Millennium Development Goals in many countries.
International community still focused on humanitarian actions to mitigate losses.
No-one is addressing disaster risk through development
What are the objectives of the Report
Demonstrate through quantitative analysis that disaster risk is an unresolved problem of development
Identify and pr ....etc

Abstract
Hand-held devices are rapidly becoming a common technology at work, school, and play. Even though battery technology is improving continuously and processors and displays are rapidly improving in terms of power consumption, battery life is an issue that will have a marked inuence on how hand-held computers can be used. Energy consumption can be reduced by the efficient usage of the three power states: Run, Idle and Sleep. _Sleep is an energy reduction technique for handheld devices which is different fr ....etc
