Usually wireless communication is preferred to wired communication within caves considering the known difficulties of laying wires and related equipment in such rugged environments. Nevertheless both the inner structures of the caves and RF challenging conditions within the caves make the use of wireless solutions, like walkie-talkies or CB radios, deficient. In this paper, we propose a Wireless Multimedia...
Sensor applications have many different constraints such as the network lifetime, the number of sensor nodes and base stations (BS). The main goal of the researchers is to maximize the network lifetime with minimum budget. BS positioning and the choice of routing algorithm are two important criteria in maximizing the lifetime. Many wireless sensor network (WSN) applications, like the intelligent agriculture,...
The experimental data of heat of mixing (Q) for heterogeneous system α-tocopherol/AOT/n-heptane with and without water at 25 °C are presented. The Q dependence on AOT (sodium bis (2-ethylhexyl) sulfosuccinate) concentration, and R parameter defined as R=[H 2 O]/[AOT] with flow calorimetric method were investigated. Using the D'Aprano model (which is formally identical to that used earlier...
