Unleash the forces within you...
The 21st Century Dictionary describes Livewire as someone who is full of energy and enthusiasm. It�s our viewpoint that our college news journal should flaunt an undying enthusiasm and energy in publishing relevant news and information for the benefit of students, faculties, parents and the external publics.
Livewire is a result of our management�s unflagging commitment to energise the student fraternity into constructive activities. Our editorial board, comprising a judicious combination of enthusiastic faculties and students, has envisioned a meaningful role for the newsletter in the days ahead.
Livewire is a forum for information dissemination, news and events, light-hearted articles, poetry, humour etc. It�s our desire to see that Livewire is not going to be just another newspaper, but a top-class journal publishing fresh news and meaningful articles. It will also act as a catalyst in bringing about positive changes in the attitude of our students.
Livewire will be published in four pages and as a quarterly in the beginning. The editorial team has plans to bring out the news letter more frequently in the future and add more number of pages. In this context, the coordination of students and faculties is critical in making this newsletter one of the most happening things on our campus.
Every editorial team commit to some goals and school of thought. Our goal is to ensure that Livewire will be an ideal platform for strengthening the thinking abilities of our students; for spurring them to perceive and understand the latest trends and happenings; and unleash the creative abilities latent in them.

Students bring laurels to MVJCE |
Once again, the MVJCE students have delivered excellent results in the August 2000 examination. By doing so, they have not only made the college proud but have also laid a sound foundation for themselves.
The Mechanical Students have given their best shot. The percentage was as high as 93% with over 68 students (out of the total 87 students) scoring first class with distinction. This result is comparable with some of the best colleges in Karnataka. The chemical engineering division was no less in comparison, having registered a pass percentage of 92%. Nearly 45% of the students of this department secured first class with distinction. And 50% of the students secured first class. The Electronics Engineering Department was another feather in MVJCE�s cap. In this department, out of the 73 students who appeared for the exams, 13 students have secured first class with distinction, while 33 students have scored first class.
The students of Computer Sciences stood a class apart by registering a pass percentage of 84%. Out of the 55 students, 17 students have
|
scored first class with distinction, while 22 students have scored first class marks.
In the Electrical Engineering of the 17 students, 6 students obtained first class, while 2 students scored first class with distinction. The In Civil Engineering (64%), of the 22 students who appeared for the examination, 5 students have obtained First Class with Distinction. And 9 students have secured first class.
Saikat Mukherjee, a final year Electrical Student has scored 87% . In Electrical Machine Design II, he stands first in the University.
In IEM (69%), 6 students have secured first class with distinction, while 5 students have secured first class. In the Telecom Engineering (65%), of the 20 students who appeared for the exams, 3 students have secured first class with distinction, while 9 students have scored first class marks.
Now with the students having delivered a sterling performance, the onus is on the MVJCE placement cell to place them in blue-chip companies. As many as 93 students have registered their names with the Placement Cell. |

MVJCE- A platform to dream big |
|
Having dreamt about Newton, Einstein and such other luminaries since my childhood and having admired their work, I aspired to become like them. I needed a place where I could nurture my dreams. I needed a launch pad from where I could think of taking on the world. With dreams as big as this, I stepped into the premises of MVJ College of Engineering.
If Bangalore is known as the garden city of India, I would not hesitate to call our college as the garden college. Situated in the outskirts of Bangalore, the campus of our College looks as if a painter has painted a beautiful picture using the best possible shades of colour.
Our college can boast of students from not only good in academics but also
|
students who have excelled in other fields. Guided by an able administration and a coordinating faculty, the students of our college have consistently been able to produce excellent results.
Our college regularly conducts and sponsors cultural events, provides
us an opportunity interact with
the students of other colleges
and opportunities to share
our thoughts, ideas and views
on different forums.
In short, our college provides
us with a fresh air to breathe.
It provides us with a forum
to showcase our talent. Above all,
it provides us a platform to
dream big.

Virtual Reality
Emerging technologies involving electronics and computers are creating synthetic perceptual environments (such as what goes on inside a movie theatre) which are indistinguishable from, and confoundable with, natural perceptual environments (such as what goes on outside the movie theatre).
A natural environment provides a blend of sensory information (sights, sounds and so forth) from which we infer the existence of a external world of objects in relation with each other.
In a synthetic perceptual environment, which is called cyberspace, sensory information is provided to the subject by machines. The best of these machines now consist of tiny projectors of visual and auditory data (miniature TV screens and headphones) which are mountable on our heads - worn as a sort of helmet. The projectors create 3-D vision, and surround-sound, and are shortly |
expected to create kinaesthetic sensations as well. The projectors are managed by computers, and the subject-user has control over the computers. This creates an interaction between the subject-user and his perceptual environment. Pulling on the throttles, changes that environment.
The expression �virtual reality� designates the technical processes by which such convincing synthetic perceptual environments are created, and signals an important human response to these environments.

The Importance
of DSP
DSP emerged as a major discipline in the 1960s. Since then, it has developed at a rapid pace over the past two decades and in recent years has made a considerable impact in vast areas of signal processing applications. In the next two decades, DSP systems will grow extensively in response to the ever growing market demand to provide and rapidly process more and more signal data transmitted over various forms of communication channels. In today�s life, almost every bit that is transacted or processed has to go through a digital signal processor. Every modem, digital cell phone, disk drive, multimedia platform, digital camera, medical diagnostic equipment, refrigerator... use DSP in some form or other.
To promote and sustain these advances there will be a great demand for engineers, scientists and technologists who have a good working knowledge of DSP concepts, design methods and practical implementation conditions. Keeping this in view, DSP should be made a must study for electrical, electronics and computer science engineers.
The growth of DSP was around 35% in the previous year. In India, Texas Instruments and Motorola have been developing DSP related applications for more than a decade. DSP related software development has been taking off in a big way over the last three years.
Today, there are at least 70 companies, from Wipro to Infosys, are working on DSP projects in Bangalore.

Science. A boon to Man kind
|
Earth, since its formation about 500 million years ago has been subjected to various changes. These changes have led to the transformation of earth from an ordinary yet unique planet into a more sophisticated dwelling. These changes brought about by science has transformed earth into a paradise in the 21st century.
Science provides all the basic needs which are necessary for an individual to survive. In olden days, agriculture was considered as a gamble with monsoon. But with better irrigation facilities, we are able to get good crops in abundance during all seasons. The invention of electric bulb has made the world a brighter place, and has wiped out darkness. The harnessing of electric energy has made life more comfortable and enjoyable. Man is able to travel to any part of the globe within a short span. Current incidents all over the world are brought to our knowledge through satellite communication.
Ages ago, human life span was considered as a gift of god, but today anyone can increase his life-span and lead a healthy and hygienic life owing to the contribution of science.Earlier, moon was considered as a divine being. By landing on the moon, |
we have successfully reached the abode of Almighty. The special device used for this purpose is a space craft which is again a gift of science. The advent of nuclear energy has brought about a tremendous transformation on earth. The nuclear energy finds its use not only in the generation of electricity but also in other constructive activities.
It is considered that science has its own limitations and drawbacks. But truly speaking, the benefits of science can be harnessed only by using it rightly. Science when used for destructive purposes can result only in destruction. Hence it is the choice of the user to decide whether science is a boon or a bane.

Smart Cards.
Making Life Simpler
|
Last year, when the Karnataka Government introduced Smart Card at the Secretariat Building, it aroused a lot of curiosity and an equal amount of controversy. The Smart Card became the hot topic of discussion for a while. Even people who had never heard about it, began to ask questions about this small microchip embedded plastic.
A smart card, simply speaking, is a credit card-sized plastic and with an embedded computer chip and some memory. You can use this for a wide-ranging activities in your daily life such as shopping, identification, paying electricity and water
|
bills, recording salary details, personal information...The histroy of smart card can be traced to the 60s and 70s, when inventors in Germany, Japan, and France filed the original patents.
Technology behind a smart card
Manufacturing a smart card involves much more than just sticking a chip on plastic. The plastic used is usally PVC (polyvinyl choloride). Other substitutes like ABC Cacryl Nitrite Gatadiene Styrenes, PC (Polycarbonate) and PET are also used. The chip, also known as micromodule, is very thin and is embedded into the
|
|
|
plastic substrate or card. Then, either a cold or hot glue process bonds the micromodule to the card.
Types of smart cards
There are two types of smart cards. Contact and Contactless. A Contact Card has to be inserted into a smart card reader for access. The micromodules have connectors that are accessed by the reader for data transfer. They are usually gold plated.
A Contactless card need will not have physical contact with the reader. On either side of the card there is an antennae which is used for communication. The antennae is typically 3 to 5 turns of very thin wire connected to the chip. You have to place the card about 2�-3� from the reader for data access. The electromagnetic signal emitted by the reader is enough to power the chip as well. Since they are quick to use, these cards can be used where a lot of people need to access the card such as a metro rail system.

Prof. U.R. Rao, The man behind India�s Spacecraft Revolution |
Prof. U.R. Rao is an internationally renowned space scientist. He has made many original contributions to the development of space technology in India and its extensive application to communications and remote sensing of natural resources. Prof. Rao started his career as a cosmic ray scientist, under the late Dr.Vikram Sarabhai. Prof. Rao, in association with the JPL group, was the first to establish the continuous nature of the solar wind and its effect on geomagnetism using Mariner 2 observations. His experiments on a number of Pioneer and Explorer spacecraft led to a complete understanding of the solar cosmic ray phenomena and the electromagnetic state of the interplanetary space. Prof U.R.Rao and his team have also carried out extensive work in X-ray and Gamma Ray high energy astronomy using rocket and satellite borne payloads.
Prof.Rao, undertook the responsibility for the establishment of satellite technology in India in 1972. It was under the guidance of U.R. Rao, first Indian satellite �Aryabhata� (1975), over 15 satellites including Bhaskara, APPLE, Rohini, INSAT-1 and INSAT-2 series of multipurpose satellites and the sophisticated IRS-IA and 1B remote sensing satellites were designed, fabricated and launched. He was also responsible for the development of the second generation remote sensing satellites IRS-IC and ID. Prof. Rao, after taking charge as Chairman, Space |

Demystifying Cryptography
With the advent of �E-Commerce�, protection of your private information such as credit card information over the net, from hackers has become imperative. Since the data between your computer and your electronic merchant travels through hundreds of networks, this sensitive data, can be easily obtained by unauthorized people with little effort and can be misused, if it is transmitted plain as it is.
Here�s where cryptography comes into play. Cryptography is the science and study of transforming clear and understandable information into unintelligible data, so that only certain people can obtain the real information. To most people, cryptography is used for keeping communication private.
The clear readable information is called clear text or plain text. Encryption is the process of transforming this clear text to unintelligible data, called the cipher text.
|
The process of getting the original clear text from the cipher text is called decryption. Cryptography deals with design of the methods (algorithms) for encryption and decryption. Cryptanalysis is the science of analysing and breaking secure communications.
The process of encryption: The algorithms designed for encryption generally use a key, which is a sequence of binary 0�s and 1�s, to encrypt information. The strength of the encryption is roughly measured as the time it takes for an unauthorized person to obtain the clear text from the encrypted data. The strength of the cipher depends on how well the algorithm uses the key and in some cases the secrecy of the key itself and also the length of the key. One such algorithm is the Data Encryption Standard or the DES. The length of the key used by United States for Commerce is 64 bits of which 56 bits are used for encryption and remaining 8 bits for error detecting. Theoretically, it would take 1500 years to get the clear text from a DES encrypted cipher, using a Pentium III class 533 MHz based computer. But, when a distributed effort using about 5000 computer systems was actually undertaken, the clear text was obtained in less than 24 hours.
Symmetric Key Encryption: In this type of cryptography, the same key is used for encryption as well as decryption. The DES is an |
|
example of this type. The problem with this kind is that the recipient and the sender should both have the same key and the medium used to make the key available to authorized persons, must be secure and trusted. The Public Key Cryptography solves this problem.
Asymmetric Key Encryption: Also known as the Public Key Cryptography, was invented by the British Secret Service but was kept classified. Whitfield Diffie and Martin Hellman invented it independently and made it known to the world in 1975. For every user of this scheme, a pair of keys is generated. One is called the public key the other called the private key. These two keys are mathematically related to each other, but it is computationally infeasible task to obtain one key, given the other key. Now you distribute your public key to anyone and publicize it. If a person wants to send you an encrypted message, he uses your public key and relevant encrypting algorithm. The cipher text so generated can be decrypted only with your private key and the decrypting algorithm. The encrypting and decrypting algorithm is available to all users, but he important thing is the length of the key. The longer the key more secure is the text. Since, ideally, you are the only one who has the private key, only you can see the clear text.

Anti- oxidants for
Safe Hearts
Coronary heart disease has become the most common of all the diseases and accounts for the highest number of deaths in India, according to the SAAOL Heart Centre. Antioxidants are chemicals which stop the oxidation of cholestrol, which is a preliminary step in the formation of coronoary arterial blockages. Intake of antioxidants in food, along with low fat vegetarian diet, yoga, meditation and stress management has the potential of reversing the blockages.
Heart patients are advised to consume whole grains, soya beans, greens, vegetables, oatmeal, capsicum and fruits like mango, papaya etc. Fresh fruits and vegetables are more effective in preventing diseases of the heart than popping those magic vitamin capsules. Nature is certainly the best cure.
