A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response time (5 s) and can be used for two m...

every year, millions of muslims from all over the world, are going to participate in the pilgrimage hajj located in mecca in kingdom of saudi arabia (ksa). the accumulation of many people from all parts of the world in terms of health management is of great importance. in fact, every person could be a carrier of various chronic or acute diseases. this huge population may lead to occurrence of s...

In recent years, lightweight steel framed (LSF) structures are designed to resist fire, earthquakes, and storm events. This system has entered the field of construction due to advantages of light members. Based on these advantages, such a system is also used for buildings with special importance. Structural health monitoring (SHM) implements a damage detection and characterization strategy for ...

in this work, a novel electrochemical technique is presented for determination of bentazonusing a nanocomposite based sensor and continuous coulometric fast fourier transformation cyclicvoltammetry (ccfftcv). in this method, the sensor response is in coulomb and is calculated based onintegrating charge changes under the current voltammogram in selected potential range. the new sensor wasconstru...

In the wireless sensor networks, resource constraints such as bandwidth and energy limitations, limited communication range, low storage and weak processing capacity motivate researchers to solving these problems. Presenting new algorithms such as efficient mobile agent based dada gathering methods would be a good solution for this case. Some of important advantages of mobile agent based data g...

In this paper we focus on the application of reinforcement learning to obstacle avoidance in dynamic Environments in wireless sensor networks. A distributed algorithm based on reinforcement learning is developed for sensor networks to guide mobile robot through the dynamic obstacles. The sensor network models the danger of the area under coverage as obstacles, and has the property of adoption o...
