SYNOPSIS
Autonomous underwater gliders, and in particular autonomous underwater gliders, represent a rapidly maturing technology with a large cost-saving potential over current ocean sampling technologies for sustained(month at a time) real-time measurements.
This report gives us an overview of the main building blocks of an underwater glider system for propulsion, control, communication and sensing. A typical glider operation, consisting of deployment, planning, monitoring and recovery will be descri ....etc

GOING GREEN WITH BLUE BLUETEC Diesel Technology
Major problem faced by today’s world is environmental pollution.
Of these vehicular traffic is a major contributor.
Exhaust gases from vehicles include CO,CO ,HC,NOx…...
Of these NOx is particularly very harmful.
These are one of the chief constituents of smog, which have an adverse effect on ecological systems.
They also contribute to the formation of acid rain.
Nox also cause breathing illness to humans.
The factors that cause that cause diesel engines ....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 betwee ....etc

The design, construction and maintenance of buildings has a tremendous impact on our environment and our natural resources. The buildings all together use the one-third of all the energy consumed in the country and two-thirds of all electricity. So the challenges is to build them smart, so that they use a minimum of nonrenewable energy, produce a minimum of pollution and costs a minimum of energy, while increasing the comfort, health and safety of the people who live and work in them. Here comes green buildings which alienates the isolation of ....etc

RECONSTRUCTION OF UNDERWATER IMAGE BY BISPECTRUM

Reconstruction of underwater object from a sequence of images distorted by moving water waves is a challenging task. A new approach is presented in this project. We make use of the bi spectrum technique to analyze the raw image sequences and recover the phase information of the true object. We test our approach on both simulated and real-world data, separately. Results show that the algorithm is very promising. Such technique has wide applications to areas such as ocean study and submarine ob ....etc

Underwater welding refers to a number of distinct welding processes that are performed underwater.

The two main categories of underwater welding techniques are wet underwater welding and dry underwater welding, or hyperbaric welding.

In wet underwater welding, a variation of shielded metal arc welding is commonly used, employing a waterproof electrode. Other processes that are used include flux-cored arc welding and friction welding. In each of these cases, the welding power supply is connected to the welding equipment through cables and ....etc

Abstract
While wireless communication technology today has become part of our daily life, the idea of wireless undersea communications may still seem far-fetched. However, research has been active for over a decade on designing the methods for wireless information transmission underwater. Human knowledge and understanding of the worldâ„¢s oceans, which constitute the major part of our planet, rests on our ability to collect information from remote undersea locations.
The major discoveries of the pa ....etc
