امروزه با توسعه روز افزون تکنولوژی mems و کاربردهای گسترده آن در مهندسی پزشکی می توان قطعاتی را طراحی نمود که قابل کاشت (implantable ) در داخل بدن باشد. اندازه گیری مقدار قند خون یکی از زمینه هایی می باشد که با توسعه تکنولوژی memsمورد توجه بوده است. در بیماران دیابتی نوع دوم، میزان قند خون بالا می باشد و از آنجایی که با افزایش قند خون احتمال بیهوشی نیز بالا می رود، لذا اندازه گیری قند خون بصورت...

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

coverage improvement is one of the main problems in wireless sensor networks. given a finite number of sensors, improvement of the sensor deployment will provide sufficient sensor coverage and save cost of sensors for locating in grid points. for achieving good coverage, the sensors should be placed in adequate places. this paper uses the genetic and learning automata as intelligent methods for...

a sensor network is made up of a large number of sensors with limited energy. sensors collect environmental data then send them to the sink. energy efficiency and thereby increasing the lifetime of sensor networks is important. direct transfer of the data from each node to the central station will increase energy consumption. previous research has shown that the organization of nodes in cluster...
