This paper examines the effect of compiler optimizations on the energy usage and power consumption of the Intel Pentium 4 processor. We measure the effects of different levels of general optimization and specific optimization. We classify general optimizations as those compiler flags which enable a set of compiler optimizations. Specific optimizations are those which can be enabled and disabled...

This paper presents the implementation of a 4-bit Arithmetic Logic Unit (ALU) using Complementary Energy Path Adiabatic Logic (CEPAL). This static adiabatic logic has proved its advantage through the minimization of the 1/2CVdd2 energy dissipation occurring every cycle. Firstly, the performance characteristics of CEPAL 4-to-1 multiplexer and full adder are compared against the conventional stat...

the prophet’s political activities in medina indicate a particular kind of power exercise in the public domain. on the other hand, after receiving shari’a, he promulgated it and enforced the related verdicts and teachings among people. realization of these two facts in his behavior turns the relationship between power exercise by him and islamic shari’a into a basic question. the relationship b...

This paper presents the survey of the smart grid technologies, including the background, motivation and practical applications. The driving forces for the smart grid technologies are presented, including the blackout, global energy crisis and environmental protection requirement. The key technology issues for building the smart grid are discussed. The crucial elements of the smart grid and thei...

Carbon dioxide causes green house effect and has been considered as a pollutant source forsafe environment. Since combustion of fossil fuel may create tremendous amount of carbon dioxide,detecting any pollutant sources would be important to eliminate the origin of pollution sources.Evaluation of smoke dispersion generated by the power plant utilizing fossil fuel is the objective of thispaper. T...
