In wireless sensor networks (WSN), the energy hole problem is the major factor which shorten the network lifetime. While transmitting the data, a sensor node dissipates energy. The energy consumption rate of sensor nodes differs with the different transmission range distance. A sensor node with the same transmission range dissipates more energy to forward the data for the short distance and it ...

Lactation is the most energetically expensive period for mammals and is associated with increased metabolism and energy intake, but decreased thermogenic capacity. It is well known that small mammals increase both food intake and thermogenesis in the cold. The present study aimed to examine whether Brandt's voles Lasiopodomys brandtii could adjust energy intake and thermogenesis to accommodate ...

The seismic performance of hybrid braces composed of steel and shape memory alloy (SMA) was investigated in this paper. Six types of hybrid braces were used, constituted by SMA content of 0, 20, 40, 60, 80, and 100%. A nonlinear dynamic analysis was performed under El Centro earthquake records, with the maximum acceleration of 0.6g and 0.9g. Our results showed that the seismic performance, i.e....

Main aim of the work is to design an energy efficient routing mechanism based on Dynamic Source Routing (DSR). In order to achieve energy efficient reliable transmission, routing here is divided into two parts. One is to discover the path based on Received Signal Strength (RSS) and residual energy and the other is to select based on minimum energy consumption. By eliminating the nodes that has ...
