CHAPTER 1 THE PROBLEM AND ITS BACKGROUND Introduction The changing needs of people led to the development of a means to make tasks a lot easier and more convenient. This is technology. It is a tool that now plays an important role in people’s everyday life. Because of this technology every complicated task is now provided with an equal solution. Hence‚ the difficulties that people experience in doing tasks are minimized. It is not impossible that in the near future‚ these difficulties will be

1. INTRODUCTION Obtaining a high-resolution (HR) image from single or multiple low-resolution (LR) images‚ known as “super-resolution” has been a problem. High resolution means high pixel density‚ also referred to as high-definition (HD). An HR image brings out details that would be blocked out in an LR image. More pixels in the same area imply a higher sampling frequency thereby offering more details. Due to the tremendous progress in sensor and chip manufacturing techniques‚ we can now obtain

the requirement for further development of the radio was an efficient‚ but delicate detector of electromagnetic radiation. Lee De Forest provided such a detector. This detector made a possible to amplify the radio frequency signal picked up by the antenna‚ before applied to the receiver detector; this meant much weaker signals can be utilized which was previously impossible. Then came A.M. and F.M. radio‚ which is used all over the world today. Then came satellite radio‚ satellite radio allows us to

Why should sandpaper never be used when preparing a scarf joint in a wing spar for splicing? The dust caused by sanding will plug the pores of the wood so the glue cannot get in to form a good bond. 12. What is the largest hole in a plywood wing skin that can be repaired with a fabric patch?

Abstract- Driverless cars are the promising approach to reduce the traffic problems. In driverless cars the frequently changing state of the road due to obstacles is controlled by array of sensors‚ which acknowledges the presence of obstacles on the driving path and creates the suitable path by frequently updating the route. This paper describes the efficient Doppler radar system and specialized algorithms to measure the speed of a vehicle used in autonomous vehicles. The velocity‚ acceleration and
