Rational Expressions‚ Asymptotes‚ and Holes Dr. Litan Kumar Saha Assistant Professor Department of Mathematics University of Dhaka Rational Expression It is the quotient of two polynomials. A rational function is a function defined by a rational expression. Examples: y x2 x5 y 3x2 2 x 5 x3 4 x2 5 x 7 Not Rational: y 4x x2 y x x2 5 Find the domain: Graph it: f ( x) 1 x Find the domain: Graph it: f ( x)

Abstract— The work deals with the healing of the coverage hole identified in a location unaware network using fuzzy logic. The hole identification is done based on the Delaunay Triangulation method and the Empty circle concept. The main contribution here is that the healing of the coverage hole is done on a location unaware network based on the energy‚ angle and distance of the nodes involved in the healing process using the fuzzy rule set. Only the partial location information like the distance

blocking a hole would prevent light from going through it‚ but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all‚ but rather enhances its transmission. In an example of the extraordinary twists of physics that can occur at very small scales‚ electrical engineer Stephen Chou and colleagues made an array of tiny holes in a thin metal film‚ then blocked each hole with an

supernatural power of the hole to their benefit. Scientists were called to come and analyze the hole‚ and put in into a scientific perspective. They concluded that the hole must be filled. One man‚ a concessionaire‚ then bargained with the village mayor‚ saying that he would rebuild the destroyed shrine closer to the village‚ in exchange for the hole. This agreement was the start of the hole-filling company. The concessionaire wanted to be more powerful‚ and by using the hole to start a business‚ he

A fox hole is bigger than a traditional spider hole and is typically dug big enough for two shooters or even more. It allows a shooter to stand and shoot while still offering cover from incoming rounds and protection from shrapnel. Fox holes located on your property would be firing positions away from the structure‚ but yet‚ close enough to get to during a fight. If you fear your shelter might be burned or bombed then you would seek cover in a fox hole. Military fox holes will have a grenade

students determine if the position of the two holes in the part meet the specified tolerance. Students are then asked to use a paper gage with their measurements to verify the results obtained in the inspection report. The last part of the activity involves having the students assemble the sample parts into a functional gage assembly that is provided by the instructor. The students then perform an interference check on the assembly to determine if the holes are within the prescribed position tolerance

Drilling Machine Chapter-4 Drilling machines Any component manufactured has one or more cylindrical hole in them. The process of making a hole is known a drilling. The cutting tool‚ which is used for making holes‚ is known as drill. The drill is a multipoint cutting tool. Definition: Drilling is the operation of making holes in a work piece using a drill bit. The hole is generated by the rotating drill‚ which exerts large force on the work piece clamped rigidly on the machine

The definition of physics is “the study of matter‚ energy‚ and the interaction between them” (Physics.org‚ 2016) Physicist working in the astronomy field are constantly making new and exciting discoveries to do with the universe. Discoveries in fields such as quantum physics‚ particle theory‚ cosmology‚ quantum mechanics and general relativity allow us to better our knowledge about the phenomena which has been observed for centuries and has pondered the minds of physicists such as Einstein‚ Feynman

describe an exciton? An exciton is a bound state of an electron and a hole in an insulator (or semiconductor)‚ or in other words‚ a Coulomb correlated electron/hole pair. It is an elementary excitation of a solid. A vivid picture of exciton formation is as follows: a photon enters a semiconductor‚ exciting an electron from the valence band into the conduction band. The missing electron in the valence band leaves a hole behind‚ of opposite electric charge‚ to which it is attracted by the Coulomb
