Energy optimization has become an important issue in hardware and software design. In particular, optimizing the energy consumed by the memory system has been found to be very important. This paper looks at the influence of state-of-theart compiler optimizations on the memory system energy considering the overall impact on instruction and data accesses. Our results indicate that while these opt...

In recent years, energy predicament and environmental problems in the world caused by fossil fuels combustion make us to pay serious attention to optimizing energy consumption and using renewable energies. One of the potential renewable energies which can be helpful in electricity generation is harness wind and water energy or using these two kinds of energy simultaneously. In this study, to pr...

the objectives of this study was to estimation of greenhouse gases (ghg) emissions and global warming in rice production and identify measures to reducing fossil energy use and greenhouse gases emissions. three rice production systems included sri, improved and conventional were studied. all activities, field operation and data in production methods and differents inputs rates were monitored an...

OBJECTIVES The article describes the after-school (AS) snacking pattern of young Canadians and its relationship with the amount of energy consumed daily and at dinner. METHODS We analyzed cross-sectional dietary data, measured by 24h recall, from 9,131 children and adolescents aged 4 to 18 years from the Canadian Community Health Survey, cycle 2.2 (2004). We evaluated AS snack intake; i.e., f...

A major challenge in designing resilient infrastructure is to meet the needs of sustainable development (Kennedy & Corfee-Morlot, 2013). Sustainable development requires a high degree of energy efficiency. Municipal wastewater treatment plants (WWTPs), in particular, have the potential to be much more sustainable. In the U.S., 3 – 4% of the total energy consumed is dedicated to WWTPs and drinki...

Energy consumption is an important concern in modern multicore processors. The energy consumed during the execution of an application can be minimized by tuning the hardware state utilizing knobs such as frequency, voltage etc. The existing theoretical work on energy minimization using Global DVFS (Dynamic Voltage and Frequency Scaling), despite being thorough, ignores the energy consumed by th...

Energy use and greenhouse gases (GHG) emissions in rainfed canola production in north eastern Iran were analyzed to find measures to reduce energy use and GHG emissions. Four production scenarios, i.e. a high-input, a low-input, a better crop management and a usual scenario, evaluated. All activities and production processes were monitored and recorded over three consecutive years. The usua...
