    Evaluating the Current Problems A normal desktop PC framework is included the PC itself (the CPU or the "case")‚ a screen‚ and printer. A normal CPU may require more or less 200 watts of electrical force. At that point‚ include 70-150 watts for a 17-19 inch screen (proportionately more for bigger screens). The force necessities of traditional laser printers which could be as higher as 100 watts or more when printing however a great deal less if sitting out of gear in "rest mode." Ink plane printers

    Introduction to Cache Memory Cache memory is a random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data‚ it looks first in the cache memory and if it finds the data from a previous reading of data‚ it does not have to do the more time-consuming reading of data from larger memory. Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same

    Fig. 3 The hybrid Nano Memristor/CMOS architecture [23]. This hybrid Nano/CMOS architecture is showing great promises in Spin-Transfer Torque Magnetic RAM (STT-MRAM)‚ which is well suited for many mainstream applications‚ especially memory storage devices [26‚ 27‚ 25‚ and 28]. By utilizing this architecture in this application‚ the size and the speed of this technology would be improved greatly. In addition‚ the read and write time for these architectures is nearly 120 picoseconds [29‚ 30]. The

    . RESULTS PRESENTATION AND ANALYSIS Solver CPLEX‚ version 12.6‚ was used to run the mathematical model on a computer with an Intel Core i7 processor with 16GB of RAM. The maximum execution time was limited to 7‚200 seconds for each instance. When running instances with CPLEX it was possible to obtain results to measure the quality of the RAS metaheuristic solution. RAS was developed in C language and run on the same computer described before with a runtime limited to 7‚200 seconds. RAS metaheuristic
