are increasing exponentialy. Therefore, large scale data centers are required in cloud environment that leads to high energy consumption. Hence, optimal resource utilization is essential to improve energy... degradation. In order to improve the existing approaches, load aware three-gear THReshold (LATHR) as well as modified best fit decreasing (MBFD) algorithm is proposed for minimizing total energy consumption......
can balance energy consumption and prevent nodes around sink from draining their energy very quickly in the networks. The simulation results show that the scheme can prolong the network lifetime by 26...-gathering period. (6) The transmission range of sensor nodes and sink are fixed and the sink’s transmission range is larger than that of sensor nodes. (7) The energy consumption for transmitting one......

operating energy consumption is nearly 20% of the total energy use. China has enacted a series of building energy efficiency standards for reducing energy consumption of buildings to cope with the increasing energy consumption. The heat transfer through the building envelope becomes cooling/heating load and results in energy consumption finally. Therefore, it is an important means to decrease......
of change in the energy consumption ratio can be used as the criteria of the crack initiation and propagation and the unstable failure of the sample, respectively. Key words: energy evolution..., and damage and failure evolution mechanism, and establishes the energy criterion of instability and failure of a jointed rock mass surrounding an opening based on the defined energy consumption ratio......
