background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...

Low-cost mini-drones with advanced sensing and maneuverability enable a new class of intelligent sensing systems. Œis trend motivated several research e‚orts to employ drones as standalone systems or to assist legacy deployments. However, several fundamental challenges remain unsolved including: 1) Adequate coverage of sizable targets; 2) Target orientation that render coverage e‚ective only fr...

The availability of low-cost mobile robots with sensing, communication, and computational capabilities has made feasible a new class of Cyber-Physical Systems (CPS). These miniCPSs may be used where quick, low-cost or non-lasting visual sensing solutions are required, e.g. in border protection and disaster recovery. In this paper, we take the first steps towards a fast and automated CPS. We con...

Wireless sensor nodes are electronic devices capable of collecting, storing, and processing environmental information, and communicating with other sensor nodes through wireless communications. Hundreds or thousands of wireless sensor nodes deployed in a region of interest comprise a wireless sensor network (WSN), where all members cooperatively monitor the whole region, barriers, or targets (p...

Utilization of Unmanned Aerial Vehicles (UAVs) in military and civil operations is getting popular. One of the challenges in effectively tasking these expensive vehicles is planning the flight routes to monitor the targets. In this work, we aim to develop an algorithm which produces routing plans for a limited number of UAVs to cover maximum number of targets considering their flight range. The...
