It gives me an immense pleasure and proud to stand in front of the graduating young friends. It reminds me the days of mine as a graduating student. First of all, I would like to congratulate all the students who are graduating today and my best wishes for future endeavours. I would like at this point to extend my regards and greetings to all the faculty members and staffs who have been part of the graduating students all those years.
with many mind-boggling and teaser situations. A lot many avenues a graduating student may encounter viz., higher studies, jobs, entrepreneur. Several young friends of you will be graduating from various institutes spread all over states and country and, will also be competing for all those avenues. Earth is such a place that it always allows each one to have their own pie depending upon their deeds. One should not get perplexed with happenings in short run. At this juncture I would like to convey an important message from Swami Vivekananda.
Many times what one studied in the college may not have any direct relations towards applications in an industry or enterprises. One should strive to synthesis the knowledge of education with the indented applications to derive the best quotient of it. One should know what role they want to play or they are into. The differences among the acts of science, technology and engineering should be understood. One of the ways those acts are explained as science brings out the knowledge of a natural phenomenon; technology converts the knowledge obtained by science to a usable entity and where as engineering is an art of exploiting the technology to suit the ease of human usability..
Electron spin can be detected as a magnetic field having one of two orientations, known as down and up. This provides an additional two binary states to the conventional low and high logic values, which are represented by simple currents. With the addition of the spin state to the mix, a bit can have four possible states, which might be called down-low, down-high, up-low, and
up-high. These four states represent quantum bits. Spintronic technology has been tested in mass-storage components such as hard drives. The technology also holds promise for digital electronics in general. The existence of four, rather than two, defined states for a logic bit translates into higher data transfer speed, greater processing power, increased memory density, and increased storage capacity, provided the properties of electron spin can be sufficiently controlled for practical applications.
These new developments not only demonstrate the physics of the concept, but also pave the way for future optical and photonic applications. In those cases one can see that there are certain opportunities waiting for engineering and for entrepreneur aspects. Further, many time solutions to certain intriguing problems are available in the nature. Nature inspires one's imagination. It is because the efficient and elegant way systems evolved in this universe whether it is living or non-living things.
Many researchers get inspired and take cue from nature and try to imitate systems to solve certain intriguing problems. In that context, think of an imager (digital camera) having wide field of view (FOV) of coarser resolution for monitoring and the same imager will be inscribing a narrow field of view of high resolution for identification or discrimination. Imager has also the capability to vary the focal length/magnification. This type of imaging is called adaptive zooming and foveated imaging. This concept originates from the vision of human eye. Progress in technologies of fabrication of optical components and detector
arrays over the years may allow realizing the above type of imaging in future in larger usable domain.
