...Scheduling Techniques for Computation Models of Image Processing on Many-Core Platforms Abstract Adding more processor core can help in the improvement of a computer performance. As a result in the number of high specification application being run on the computer, it reduces the processing ratio of processor core. This journal focuses on how the system resources is being shared. It also explains how an algorithm is being use to share, map and schedule task for more processor cores. At the end of the research, the algorithm states how the processor core are being improved greatly by 64.77% . with the speed up ratio of 43.55 can be obtained if 48 process unit is employed and are all activated and 10% will be the performance ratio. Introduction Demand for high definition image of modern images made the computation working application much higher. To achieve efficiency improvements were needed on the system architecture. The frequency of single core processors could not have any impact on the processor cores even when the frequency is increased, as a result processors with higher computation power were employed. Today a number of parallel image processing algorithms with emphasis in manipulating the arithmetical level ignoring the limitation of hardware in a many processor core machine and are also developed for many core system. In other to know how to utilize the said algorithm, a dedicated (special) hardware structure must be put in place since a special communication channel is...

...principal theme in today’s world of electronics industries. Power dissipation has become an important consideration as performance and area for VLSI Chip design. With shrinking technology reducing power consumption and over all power management on chip are the key challenges below 100nm due to increased complexity. For many designs, optimization of power is important as timing due to the need to reduce package cost and extended battery life. For power management leakage current also plays an important role in low power VLSI designs. Leakage current is becoming an increasingly important fraction of the total power dissipation of integrated circuits. This paper describes about the various strategies, methodologies and power management techniques for low power circuits and systems. Future challenges that must be met to designs low power high performance circuits are also discussed. Keywords: Power Dissipation, low power, process nodes, leakage current, power management. 1. Introduction The advantage of utilizing a combination of low-power components in conjunction with low-power design techniques is more valuable now than ever before. Requirements for lower power consumption continue to increase significantly as components become battery-powered, smaller and require more functionality. In the past the major concerns for the VLSI designers was area, performance and cost. Power consideration was the secondary concerned. Now a day’s power is the primary concerned due to the...

...pipeline concatenation of speech-to-text recognition (SR), text-to-text translation (MT) and text-to-speech synthesis (SS). This paper proposes and illustrates an evaluation methodology for this noisy channel which tries to quantify the relative amount of degradation in translation quality due to each of the contributing modules. A small pilot experiment involving word-accuracy rate for the SR, and a fidelity evaluation for the MT and SS modules is proposed in which subjects are asked to paraphrase translated and/or synthesised sentences from a tourist’s phrasebook. Results show (as expected) that MT is the “noisiest” channel, with SS contributing least noise. The concatenation of the three channels is worse than could be predicted from the performance of each as individual tasks. 1. Introduction Evaluation is without doubt a major aspect of language engineering, including Machine Translation (MT). Although it is still true that no consensus exists regarding the best way to evaluate software, there is general agreement about some of the factors that must be taken into account when deciding what form an evaluation should take. MT evaluation has been much studied in recent years, so much so that it has been light-heartedly claimed that MT evaluation “is a better founded subject than machine translation” (Wilks, 1994:1). If this is no longer strictly true, it is because MT is arguably in pretty good shape, at least text-to-text MT of restricted texts or for restricted purposes. This...

...HISTORY OF THE COMPUTER ARTICLE WRITTEN BY: ADEBOWALE ONIFADE ELECTRICAL ELECTRONIC ENGINEERING DEPARTMENT UNIVERSITY OF IBADAN NIGERIA REGION 8 HISTORY OF THE COMPUTER ABSTRACT This paper takes a keen look at the history of computer technology with a view to encouraging computer or electrical electronic engineering students to embrace and learn the history of their profession and its technologies. Reedy (1984) quoted Aldous Huxley thus: “that men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.” This paper therefore emphasizes the need to study history of the computer because a proper study and understanding of the evolution of computers will undoubtedly help to greatly improve on computer technologies. INTRODUCTION The word ‘computer’ is an old word that has changed its meaning several times in the last few centuries. Originating from the Latin, by the mid-17th century it meant ‘someone who computes’. The American Heritage Dictionary (1980) gives its first computer definition as “a person who computes.” The computer remained associated with human activity until about the middle of the 20th century when it became applied to “a programmable electronic device that can store, retrieve, and process data” as Webster’s Dictionary (1980) defines it. Today, the word computer refers to computing devices, whether or not they are electronic, programmable, or capable of ‘storing and retrieving’ data...

...TECHNOLOGY FOUNDATION 1 Compiled By: RONKY F. DOH (aka: ronky biggy diggy daddy igp) FU DAME TALS OF COMPUTERS We are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates students’ grades...

...Google File System Sanjay Ghemawat, Howard Gobioff, and Shun-Tak Leung Google∗ ABSTRACT 1. INTRODUCTION We have designed and implemented the Google File System, a scalable distributed file system for large distributed data-intensive applications. It provides fault tolerance while running on inexpensive commodity hardware, and it delivers high aggregate performance to a large number of clients. While sharing many of the same goals as previous distributed file systems, our design has been driven by observations of our application workloads and technological environment, both current and anticipated, that reflect a marked departure from some earlier file system assumptions. This has led us to reexamine traditional choices and explore radically different design points. The file system has successfully met our storage needs. It is widely deployed within Google as the storage platform for the generation and processing of data used by our service as well as research and development efforts that require large data sets. The largest cluster to date provides hundreds of terabytes of storage across thousands of disks on over a thousand machines, and it is concurrently accessed by hundreds of clients. In this paper, we present file system interface extensions designed to support distributed applications, discuss many aspects of our design, and report measurements from both micro-benchmarks and real world use. We have designed and implemented the Google File System (GFS) to...

...and gas takes place through pipelines. India is far behind these countries in realizing the full potential of pipelines because it does not have a well-developed pipeline network. A rapid development of pipelines, therefore, is essential to ensure that the share of this mode in the transportation of petroleum products and natural gas reaches the desired level. It is estimated that around Rs 30,000 crore are likely to be invested over the next 10-12 years in setting up pipeline networks for liquid petroleum products The efficient and effective movement of natural gas from producing regions to consumption regions requires an extensive and elaborate transportation system. In many instances, natural gas produced from a particular well will have to travel a great distance to reach its point of use. The transportation system for natural gas consists of a complex network of pipelines, designed to quickly and efficiently transport natural gas from its origin, to areas of high natural gas demand. Transportation of natural gas is closely linked to its storage, as well; should the natural gas being transported not be required at that time, it can be put into storage facilities for when...
