Society wastes much more energy than it should. This produces tons of unnecessary CO2 emissions. This is partly due to the inadequate use of electrical devices given the intangible and invisible nature of energy. This misuse of devices and energy unawareness is particularly relevant in public spaces (offices, schools, hospitals and so on), where people use electrical appliances, but they do not...

The U.S. Dept. of Energy estimates that there are more than 40,000 distillation columns in North America, and that they consume about 40% of the total energy used to operate plants in the refining and bulk chemical industries (1). Improving the energy efficiency of this unit operation, therefore, is important to achieving overall plant energy savings. Reducing the energy consumption of distilla...

Society is becoming increasingly aware of the impact that our lifestyle choices make on energy usage and the environment. As a result, research attention is being directed toward green technology, environmentally-friendly building designs, and smart grids. This paper looks at the user side of sustainability. In particular, it looks at energy consumption in everyday home environments to examine ...

In this paper we analyze energy usage in divisible load processing. Divisible load theory (DLT) applies to computations which can be divided into parts of arbitrary sizes, and the parts can be independently processed in parallel. The shortest schedule for divisible load processing is determined by the speed of computation and communication. Energy usage for such a time-optimum schedule is analy...

The utility of orthogonal collocation methods in the solution of optimal control problems relating to Formula One racing is demonstrated. These methods can be used to optimise driver controls such as the steering, braking and throttle usage, and the optimisation of vehicle parameters such as aerodynamic down force distributions. Of particular interest is the optimal usage of energy recovery sys...

The displacement of non-renewable fossil fuels by renewable energy resources has occurred at a low rate in the USA. But a large number of drivers is expected to cause significant expansion of the US renewable energy industry in the near future. Included among the extrinsic drivers, or those that are not directly related to renewable energy resources, are reductions in natural gas and crude oil ...

In the present world, energy is indispensable for maintaining the comfort level and living standard of the human. On the other hand, the energy crisis is a major problem in most of the developing countries like Bangladesh. A possible reason is that, the decreasing level of conventional energy sources and the lack of initiatives for introducing the alternative sources of energy. Moreover, the in...
