AIR INDEPENDENT PROPULSION SYSTEM FOR SUBMARINES
ABSTRACT
Air independent propulsion (AIP) system is a term that encompasses technologies, which allow a submarine to operate without the need to surface or use a snorkel to access atmospheric oxygen. The term usually excludes the use of nuclear power, and describes augmentation or replacing the electric propulsion system of nonnuclear vessels. AIP is usually implemented as an auxiliary source. Most such systems generate electricity which in turn drive an electric motor for propulsion or recha ....etc

Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

Solar water heater

Solar water heating or solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. The system may use electricity for pumping the fluid, and have a reservoir or tank for heat storage and subsequent use. The systems may be used to heat water for a wide variety of uses, including home, business and industrial uses. Heating swimming pools, underfloor ....etc

Non-Linear Analysis and Design of Perforated Thin-walled Steel Strutures

Introduction
Perforated thin-walled steel structures are widely used, however, current design guidelines for them are limited to very few specific cases.
The seminar will try to describe a proposed method to develop new design guidelines for this kind of structures by using the Direct Strength Method (DSM) which is a fast and easy design method for cold-formed steel structures, with great potential for complex and optimized cross sections.

Based on the recently de ....etc

ABSTRACT
Password is a common mean of implementing security. Dallas Semiconductor has developed a new Java-based, computerized ring that will automatically unlock doors and log on to computers. This java based technique overcomes the deficiencies of the secret password. A Java Ring is a finger ring that contains a small microprocessor which runs JVM and is preloaded with applets. The jewel of Java Ring is Java iButton, which is a microchip enclosed in a secure package. There are many technologies similar to ....etc

ELECTROACTIVE POLYMERS(EAP)
ABSTRACT
Electro active polymers are soft actuation materials that are fastly replacing the conventional actuating materials such as piezo electric crystals, motors, screws etc:- As the name suggests, they essentially consists of a ionic polymer back bone metallic composite having positive counter ions. On the application of an electric field or small voltage, these EAPâ„¢s will bend towards the anode.
They have properties resembling human muscles a ....etc

Biologically Inspired Robotic Fish
Introduction
Robotic fish is a biomimetic robot obtaining its design inspiration from aquatic animals. Ex : Shark Fish, Eel, Tuna etc.
For long researchers have been interested in the highly efficient propulsion of fish and now have attempted to apply it to underwater robots for fish-like swimming mechanisms
Why Robotic Fish ?
With increased horizons of underwater applications, there is much pressing on efficient equ ....etc

Abstract
This article presents AmphiBot II, an am-phibious snake robot designed for both serpentine loco-motion (crawling) and swimming. It is controlled by anon-board central pattern generator (CPG) inspired bythose found in vertebrates. The CPG is modelled as achain of coupled nonlinear oscillators, and is designed toproduce travelling waves. Its parameters can be modi-¯ed on the °y. We present the hardware of the robot andthe structure of the CPG, then the systematic parametertests done in simulation and with the real robot to cha ....etc
