Recent breakthroughs in micro sensor technologies allow us to engineer compact, battery powered, wireless communication enabled and cheap sensing devices, sensor nodes. Combining those cheap sensor nodes into networks allows us to create Wireless Sensor Networks (WSN). Figure.1 shows the general architecture of a typical WSN. Sensor nodes are usually low power, with limited computational and st...

The core of a successful sense of presence is a visually, aurally, and haptically compelling experience. In this paper, we introduce the integration of vision and haptics for the purposes of remote collaboration. A remote station acquires a 3D-model of an object of interest which is transmitted to a local station. A user in the local station manipulates a virtual and the remote object as if he/...

In this paper, we study the sharing of a radio access network infrastructure by two mobile operators. Knowing the possible locations of the base stations, each operator chooses to invest or not on a base station, and its aim is to maximize its profit. We characterize the existence of Nash equilibria in such a game and we measure their quality with respect to the maximization of the overall prof...

In this paper a time delay compensation control structure for a robot teleoperation system is presented. The structure design was made considering 1.9-seconds time delay in the communication between the remote and local stations. The objective is to control both the remote manipulator’s position and force. Force and position signals are fedback to the local station so that the human operator fe...

The capabilities to perform missions in hostile and/or hardly accessible areas reducing human risks are responsible of the growing interest in Uninhabited Air Vehicles (UAVs) characterizing the last years. Recent advances in Information and Communication Technologies have allowed to scale sizes of uninhabited aerial platforms, and hence to perform mission profiles not possible for conventional ...

OBJECTIVES This article compares 2 variants of logging technologies at the motor-manual level: variant A - cutting and delimbing by means of a petrol chainsaw, skidding with the use of a cable winch mounted on a tractor (67-74 kW); variant B - cutting by means of a petrol chainsaw, skidding, debranching and cutting to length by means of a processor aggregated with a farm tractor (61 kW). MATE...

Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. As sensor nodes are battery driven, an efficient utilization of power is essential in order to use networks for long duration hence it is needed to reduce data traffic inside sensor networks, reduce amount of data that need to send to base station. The aim of the project is to develop scalable ...

gasoline filling station workers Ansari-Lari et al reported that the sex ratio (proportion male) of offspring of men exposed to petroleum fuel is significantly low as contrasted with controls. If confirmed, this is an important result. It is in contrast with reports of significantly high offspring sex ratios in communities exposed to active seepages of natural gas and oil and to petrochemical a...

Long-term measurements of CO(2) flux can be obtained using the eddy covariance technique, but these datasets are affected by gaps which hinder the estimation of robust long-term means and annual ecosystem exchanges. We compare results obtained using three gap-fill techniques: multiple regression (MR), multiple imputation (MI), and artificial neural networks (ANNs), applied to a one-year dataset...

An LPG filling station incident in Korea has been studied. The direct cause of the incident was concluded to be faulty joining of the couplings of the hoses during the butane unloading process from a tank lorry into an underground storage tank. The faulty connection of a hose to the tank lorry resulted in a massive leak of gas followed by catastrophic explosions. The leaking source was verified...
