Eighty per cent of total electricity produced in the world ,is hydal,while remaining 20% is produced from nuclear,thermal,solar,geothermal energy & from magnato hydrodynamic (mhd) generators.

MHD power generation is a new system of electric power generation which is said to be of high efficiency and low pollution. In advanced countries MHD generators are widely used b ....etc

EXTRAORDINARY MAGNETO RESISTANCE

Data handling is one of the major challenges currently faced by the technological world. It is a major issue in terms of storage capacity and in read-write speeds. But the technology to increase storage capacity has been somewhat solved out as new and advanced technologies are introduced to solve this problem. But the problem of read- write into these ultra high density storage disks at good speeds is a major problem. With the current technology which is available now, however large the storage capacity be, t ....etc

Definition

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdo ....etc

introduction
 The magnetohydrodynamic propulsion is a new propulsion system which is used for propelling ships & submarines.
 The magnetohydrodynamic, or MHD, propulsion has no moving parts like propeller, gear, shafts etc
 Submarines fitted with it , cannot be detected easily
(as it is silent)
History
 First proposed by W A Rice in 60’s in USA
 He does experimental work on it using dc direct drive propulsion using battery driven magnets
 Speed 1.5 ....etc

ABSTRACT


A good dynamics model is essential and critical for the successful design
of navigation and control system of an underwater vehicle. However, it is
difficult to determine the hydro2dynamics forces, especially the added m ....etc

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc

IDENTIFICATION OF UNDER WATER VEHICLE HYDRODYNAMIC EFFICIENTS USING FREE DECAY TESTS



INTRODUCTION
In recent years there has been an ever increasing number
of applications for unmanned underwater vehicles
(UUV) in various tasks, for instance in surveying and
exploration, or in missions such as the positioning
of underwater laboratories (Aguiar 1997). Improvements
in the evaluation of the hydrodynamic models
of UUV’s result in more effective control s ....etc
