Allele frequency

I. INTRODUCTION The performance of present computing systems has increased at the cost of considerably enlarged power consumption. The increased power consumption either reduces the operation time for battery powered systems, such as hand-held mobile systems, or generates extreme amount of heat and requires expensive sophisticated packaging and cooling technologies, especially for complex systems that consist of several processing units. The generated heat, if not efficiently removed, can also…

Chapter 5 Proximity Sensor 5.1 Introduction A proximity sensors is the sensor able to detect the presence of nearby objects without any physical contact. A proximity sensors often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor target demand different sensor. For examples a capacitive or photoelectric sensors…

In the first place let begin by saying what is the (LRAD)? It is The Long Range Acoustic Device. Which is a loud megaphone/microphone or speaker to convey important messages to individuals who makes loud noise and disturb the environment. Certainly, the LRAD is not a less lethal weapon. Of course, the LRAD is used to get the attention of a large crowd or a criminal is about to break the law by disturbing the peace. The LRAD once in operation will get the attention of the troublemaker, prevent…

microchip placed into things like: supermarket items(known as the barcode), inside people, pets, computers, phones, etc. to track them down, read their data and transfer files to and from. An RFID tag is a Radio frequency identification device(Tag You're It 72). It contains radio frequency which means anyone with an RFID tag reader can receive radio waves and see whatever the RFID tag contains. Even Though RFID’s track kids and pets that ran away from home, they should not be used because they…

wireless local area network (WLAN), cellular phone, medical applications. and satellite communication. As shown in Fig. 1, The Microstrip Patch Antenna consists of a metallic patch above a ground plane. The shape and size of patch determine the frequency of operation of the antenna and its…

1.1 Overview: In antenna theory of analysis and design, the most forward looking topic is microstrip patch antenna. Microstrip patch antennas are made to have many different geometrical shapes and dimensions but among all the shapes of microstrip patch, four of them are most common than another that are square, rectangular, dipole and circular. They are employed in wide range of modern applications because of their easiness to design and compatibility with printed-circuit technology. The basic…

Extra Extra read all about it Haarp, An Government Weapon? On 1993 in Gakona, Alaska something weird was born a machine that most people didn’t know could be so powerful. Haarp, an High frequency active auroral research program is what Haarp Actually stand for if you do not know. Most people think that this machine is very dangerous, Most know this machine can change the world. Money, an issue any person can have trouble with. Haarp has gotten millions 300 (to be exact) of tax dollars every…

Origin of Species” in 1859, natural selection has been widely accepted by the scientific community as the engine that drives evolution, or the change of frequency of heritable characteristics in a population over time. Natural selection results in the survival of the fitter individuals of a given population, and therefore the increase in frequency of the genes that produced the adaptive phenotype. For natural selection to occur, there are three conditions that must be met. First and foremost,…

In some populations, alleles can be lost due to random events. Genetic drift reduces allele frequencies in smaller population, therefore, decrease genetic variation. It can eliminate alleles at a faster rate in smaller population until they become fixed in the population. On the other hand, alleles in a large population rarely become fixed by genetic drift. This indicates that genetic drift has a greater effect on a smaller population by getting rid of alleles at a faster rate. Genetic variation…

as a change in allele frequencies from one generation to another generation with time. To test the evolution theory, Drosophila was chosen as a great experiment organism because of its short life cycle, rapid development, its small size and the large amount of breeding data can be produced. There are two types of allele of Drosophila observed which are ebony allele and wild-type allele. While wild type allele is dominant and easily found in nature, the ebony type is a recessive allele causing…
