Time Travel Article

The Alternate Universe time travel explains a lot. This type of time travel depends upon the existence of alternate universe which are more or less similar to our universe but lagging in time i.e. representing a previous time. If one changes past, in that universe, nothing will happen to our universe and nothing much will be different for that universe either because that universe will evolve taking that change for granted so there will be no grand father paradoxes neither entropy or causality problems

Yawning Article

The yawning is a reflex caused due to excess of carbon dioxide and lack of oxygen in the blood. The brain stem detects this and triggers the yawn reflex, through its non vital nuclei in medulla oblongata. Recently it has been suggested by some scientists that yawning is used for regulation of body temperature, too. The yawns are also caused by the same chemicals produced in human nervous system often called neurotransmitters like serotonin, dopamine, glutamic acid and nitric oxide. When their quantity is above their optimum level in the brain, it causes yawning.

My Face Recognition

I am a dream chaser. I have always had a great fascination for face recognition. This field has amazed me forever. Face recognition may seem an easy task for humans, and yet computerized face recognition system still can not achieve a completely reliable performance. The difficulties arise due to large variation in facial appearance, head size, orientation and change in environment conditions. Such difficulties make face recognition one of the fundamental problems in pattern analysis. In recent years there have been a growing interest in machine recognition of faces due to potential commercial application such as film processing, law enforcement, person identification, access control systems, etc. This field is growing at a very rapid pace in almost all fields of life. This has been mostly due to the increase in the crime these days. Such sophisticated technology can somehow help us in reducing the occurrence of such crimes.
