As single server executes instructions for multiple clients, the amount of power consumed by server is more because the server's CPU frequency will be more and server has to be online for as long a... ... middle of paper ... ...ndemir, M., Vijaykrishnan, N., Sivasubramaniam, A., Irwin, M.J. 10.Sleepless in Seattle No Longer Joshua Reich, Michel Goraczko, Aman Kansal, Jitendra Padhye
Many different approaches are used to reduce power consumption at the circuit level design. Some of the main techniques are Transistor Sizing, Voltage Scaling, Voltage Islands, Multiple Threshold Voltages and Power Gating. There is a negative effect with each power optimisation technique used at the expense of performance or area. Rabaey (1996) states that Transistor Sizing (TS) technique is used to adjust the size of each transistor (smallest element in the digital system) or gate (group of transistors)
Process tuning strategy is to minimize the average power consumption of multi-core processors that use the DVFS and CG techniques, while providing the same maximum performance. By scaling the supply voltage (VDD), maximum operating frequency is increased to enhance the performance of a multi core processor. However, increasing VDD is limited by the power and thermal constraints. These constraints can be determined by capacity of supply voltage regulators and cooling solutions in the computing platforms
Image Compression is used to reduce the number of bits required to represent an image or a video sequence. A Compression algorithm takes an input X and generates compressed information that requires fewer bits. The Decompression algorithm reconstructs the compressed information and gives the original. A compression of medical image is an important area of biomedical and telemedicine.In the medical application image study and data compression are quickly developing field with rising applications
attract shipping lines because they are natural gateways to rich hinterlands” (p. 581), and so is it with containerized freight shipping business. Patterns and processes of competition between seaports have changed and can be expected to remain quite dynamic in the face of fast-paced changing business environments (Meersman et al., 2010). The purpose of this chapter is to depict the state of inter-port competition from a multidimensional perspective. To this end, we adopt the framework of the “functional
As we all know that Exascale computers runs million processors which generates data at a rate of terabytes per second. It is impossible to store data generated at such a rate. Methods like dynamic reduction of data by summarization, subset selection, and more sophisticated dynamic pattern identification methods will be necessary to reduce the volume of data. And also the reduced volume needs to be stored at the same rate which it is generated in order to proceed without interruption
Wi-Fi is a technology that allows the interchange of data and connection to the internet using radio waves. The name Wi-Fi was a brand name which in English is a synonym of the word "WLAN" (Wireless Local Area Network). The Institute of Electrical and Electronic Engineers (IEEE) defines it as any WLAN products on their 802.11 standards that complete the Wi-Fi Alliance interoperability certification test may only use the “Wi-Fi Certified” Trademark. As of today, more and more devices are starting
Introduction Computer Graphics is the bond between humans and computers. Computer graphics is a large field that branches into almost all fields of computer science; however its roots are young. Computer graphics has massively grown over the past 40 years and is now our primary means of communication with computer applications. Do to technological limitations in the 1950s, computer graphics began as a small, specialized field. The Whirlwind project at the Massachusetts Institute of Technology is

tv reality show currently boasting scandals, and sensational events and the media are using this emotion to frame issues to evoke the desired emotional response. Most of these diagnoses according to Braden and Marcus are directed at reducing the frequency and intensity of emotional appeals in the domain of politics (p. 175). Emotion is an unavoidable and undeniable part of human nature. Arguments over the last three decades are the exclusion of emotion from final judgments
THE ECONOMIC EFFECTS OF CLIMATE CHANGE IN KENYA Introduction 1.1 Background The evidence of climate change in Kenya is undeniable, while its effects on economic growth are no more mysterious; rather, they are rapidly unfolding to a startling reality and concern for humankind. Accelerated emissions of green house gases (GHGs) globally, from combustion of fossil fuels and unsustainable land use practices is the key driver of anthropogenic climate change. Climate change is manifested in; variations
