e-shark

E-shark or electronic shark is automated underwater vehicle. Automation of conventionally available underwater vehicles can be achieved by employing current technologies. The need for e-shark arises due to reasons via.,
INTRODUCTION
Man has always learned things from what he sees around him and tried to implement them in constructive way, so as give comfort to his life. Our e-shark too, is an idea that came through from the fascinating war games that we play. The intelligent enemy attacks us from all possible ways and we are provided with all possible ways to counter attack him.
“Why should this happen only in games? Can’t the existing technology make it a real time war game?” The answer is “yes”. With the existing technology of electronics and communication systems this war game can be made a real war field. In this pursuit, we have considered the possibility of making automated submarine, e-shark.
WHAT & WHY?
• Avoiding life risk to people working in underwater vehicles.
• Reduction in expenditure made for safety measures in underwater vehicles.
• To reach abyssal depths and to perform operations at remote locations.

GROUND IMPROVEMENT TECHNIQUES(CIVIL)

                   Ground improvement is the most imaginative field of geotechnical engineering. It is a field in which the engineer forces the ground to adopt the project's requirements, by altering the natural state of the soil, instead of having to alter the design in response to the ground's natural limitations. The results usually include saving in construction cost and reduction of implementation time.

                   There are number of techniques available for improving the mechanical and engineering properties of the soil. However, each technique has some limitations and suit abilities to get maximum improvement in the soil conditions with minimum effort. Some of the important techniques are discussed in this paper.

                   To improve the strength of the soils, especially in case of granular type of soils, COMPACTION METHODES are found as best methods among all type of techniques. Based on the mechanism applied for compacting the soil, it is sub divided into different methods like dynamic compaction, blasting, vibro techniques ...etc.These are briefly discussed in this paper. 

                    When there are some limitations encountered for applying the above technique, grouting techniques, stabilization of soil using different admixtures can be adopted effectively which can bring variations in the soil conditions. The various types of above techniques are briefly discussed in this paper.

                     Finally, recent advancements in ground improving techniques using GEOTEXTILES, ELECTRIC TREATMENT METHODES are also briefly discussed in this paper. These techniques are widely used in these days.

Future mechanics (Mech)

All engineering components and structures contain geometrical discontinuities – threaded connections, windows in aircraft fuselages, keyways in shaft, teeth of gear wheels, etc. The size and shape of these features are important since they determine the strength of the artifact. Conventionally, the strength of components or structures containing defects is assessed by evaluating the stress concentration caused by the discontinuity features. However, such a conventional approach would give erroneous answers if the geometrical discontinuity features have very sharp radii.

What a BOSS!!!!

Dear all, this post is not about technology or about education. But still I want to share since it was about the person who loves education and students, Please have a look at it

WHAT A BOSS !!!

There were about 70 scientists working on a very hectic project. All of Them were really frustrated due to the Pressure of work and the demands of their boss , but everyone was loyal to him and did not think of quitting the Job.

One day, one scientist came to his boss and told him - Sir, I have promised my children that I will take them to the Exhibition going on in our Township. So I want to leave the office at 5 30 PM.

His boss replied "OK, You're permitted to leave the office early today"

The Scientist started working. He continued his work after lunch. As usual He got involved to such an extent that he Looked at his watch when he felt He was close to completion. The time was 8.30 PM. Suddenly he remembered the promise he had given to his children.

He looked for his boss, He was not there. Having told him in the morning Itself, he closed everything and left for home.

Deep within himself, he was feeling guilty for having disappointed his Children.

He reached home. Children were not there. His wife alone was sitting in the hall,and reading magazines.

The situation was explosive, any talk would boomerang on him.

His wife Asked him "Would you like to have coffee or shall I straight away serve Dinner, if you are hungry.

The man replied "If you would like to have coffee, I too will have ; but what about our Children ??"

Wife replied "You don't know ?? Your manager came here at 5.15 PM And has taken the children to the exhibition "

What had really happened was ...

The boss who granted him permission was Observing him working seriously at 5.00 PM.

He thought to himself, this Person will not leave the work, But if he has promised his children, they should enjoy the visit to the exhibition.

So he took the lead in taking them to exhibition

The boss does not have to do it every time.

But once it is done, loyalty is Established.

That is why all the scientists at Thumba continued to work under their boss Even though the stress was tremendous.

By the way , can you hazard a guess as to who the boss was..?

Design and implementation of brain controlled wheelchair

Traditionally the brain has been under constant research and the source of numerous technologies. One such

technology, brain machine interface, is the extraction of brain signals and their use in real time applications. The brain consists of three main regions of which the cerebellum is focused on by this technology. This technology uses electrodes to extract signals from corresponding regions of the brain and use these signals to operate devices.

                                              This paper does progressive work and continues in the lines of research done

presently in this field and their applications. The concentration is given to a wheelchair that has been designed to work on the extracted brain signals. Extraction of brain signals from various regions of the brain using both invasive and noninvasive techniques and the use of this signal in real time applications has been shown in this paper with the development of brain controlled wheel (BCW) chair, a device

for persons with total neural failure and other degenerative neural disorders. The model for BCW has been simulated with necessary algorithms and programs. Finally the unbound applications of this technology in

futuristic applications have been shown in this paper.

TSUNAMI AND EARTHQUAKE ALERT SYSTEM

                             Earthquakes and Tsunamis strike without warning. The resulting damage can be minimized and lives can be saved if the people living in the earth quake-prone area are already prepared to survive the strike. This requires a warning before the strong ground motion from the earthquake arrives. Such a warning system is possible because the energy wave released at the epicenter travels slower (at 3.5 to 8km/s) than light, which is the principle behind developing this application.

                          The warning signal from the earthquake or tsunami epicenter can be transmitted to different places using the satellite communication network, fiber-optics network, pager service, cellphone service or a combination of these. The satellite based wireless network such as ISS is idle if system has to cover a large continent like ASIA.

                                                   The credential part of the paper lies in the applications part where the applications of ISS as an alert system for “EARTHQUAKE and TSUNAMI” like natural disasters with which the casualties can be reduced drastically. For EARTHQUAKE, TSUNAMI-prone countries like Indonesia, Japan seismic alert system using the ISS network spread throughout the earth is proposed here.

           This paper unleashes the system facts such as the network architecture and coverage, satellite constellation, Frequency plan and modulation of ISS system and its operation along with its advantages and applications. Last but not least, the innovative application of ISS as TSUNAMI, EARTHQUAKE alert system is explained in brief.

PALM VEIN TECHNOLOGY

With the increase in technology threat to personal data and national security had also increased .The methods that were developed to secure important information from outside intervention were not up to safe mark .There was a need to introduce a technology that secures our data more efficiently from unlawful intervention .

 Fujitsu has developed a palm vein pattern authentication technology that uses vescular patterns as personal identification data .Vein recognition technology is secure because the authentication data exists inside the body and is therefore very difficult to forge. It is highly accurate.  This technology can be used in various fields like banking, hospitals, government offices, in passport issuing etc. Business growth will be achieved with these solutions by reducing the size of the palm vein sensor and shortening the authentication time. This paper is about the palm vein technology, its applications, how this technology is applied in real time applications and the advantages of using this technology.
