This paper addresses the problem of robust sensor placement for large scale linear time-invariant systems. Two different concepts of robustness are analyzed: 1) the robustness with respect to one sensor failure, and 2) the robustness with respect to one link failure. We show that both aforementioned problems can be posed as a set cover problem. Due economic constraints we may be interested in c...

Implementation of low cost sensor nodes in recent years allow sensor nodes to be applicable in many different areas e.g. environment monitoring, homeland security and disaster relief operations. One major contribution is their high demand on data acquisition. Real-time data acquisition is more challenging and promising issue in these application areas. There are many approaches and solutions pr...

  Omni directional mobile robots have been popularly employed in several applications especially in soccer player robots considered in Robocup competitions. However, Omni directional navigation system, Omni-vision system and solenoid kicking mechanism in such mobile robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, a comprehensi...

one of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. as a result, the tool would be worn and its life time would be reduced. therefore, in long time machining, it is essential to change inserts and tools, continiously. a milling tool with self rotary cutting inserts was designed and manufactured that enables i...

Detection of fuel adulteration in real time is the most important need of the world as it generates the hazardous effects on the environment, living and nonliving things. Various automotive users and fuel providers may mix kerosene in petrol and diesel. Adulterated fuel increases air pollution, as well as reduces the performance of vehicle engines. Such a malpractice in fuel is prevailing becau...

Recently, the debate over the integration of Wireless Sensor Networks (WSN) and Radio Frequency Identification (RFID) has garnered an increasing amount of attention despite their appearing to be disparate technologies. On one hand, the RFID community realizes how adding sensor data to their infrastructures could provide added value to the RFID-based services. On the other hand, the use of uniqu...
