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 betwee ....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 spe ....etc

ABSTRACT
Bio-technologies have evolved into viable treatment technologies not only for odorouscompounds, but more complicated mixed airstreams that include volatile organiccompounds (VOCs). Digestion of compounds such as benzene, toluene, ethylbenzeneand xylene (BTEX) have been of particular interest in petroleum processes and clean-upprojects as an alternative treatment to incineration technologies.A bio-oxidation treatment process, bioremediation, has been successfully implemented ina variety of projects and conditions. Tak ....etc

UTILIZATION OF PAPER INDUSTRY EFFLUENT AS WATER REDUCING AGENT IN CONCRETE


ABSTRACT


The present paper describes the utilization of paper industry effluent as water reducing agent in concrete for its effects on various properties like slump, setting time, compressive strength etc. The properties have been compared with commercially available water reducing agents like modified lignosulphonate (MLS) and sulphonated naphthalene formaldehyde condensate (SNF). It has been observed from studies ....etc

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, w ....etc

Reducing Delay and Enhancing DoSResistance in Multicast Authentication
Through Multigrade Security

IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY, VOL. 1, NO. 2,
Language java

Abstract—
Many techniques for multicast authentication employethe principle of delayed key disclosure. These methods introducedelay in authentication, employ receiver-side buffers, and are susceptibleto denial-of-service (DoS) attacks. Delayed key disclosureschemes have a binary concept of authentication and do not incorporate
any notion of pa ....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

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

Reducing Liter on Roadsides explores the state of the practice in reducing roadside litter as it involves state departments of transportation (DOTs). The report provides information concerning the prevention and removal of roadside litter, unfulfilled needs, knowledge gaps, and underperforming activities. It covers enforcement, education, awareness, and engineering methods for both litter prevention and collection.
