Rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. Among different techniques, RSS-based  schemes and in particular oneof its variants which is based on Graph-based Semi-Supervised Learning (G-SSL) are widely-used approaches The superiority of this scheme is that it has low setup/training cost and at the same ti...

Abstract. Today, natural disasters have a huge impact all over the world, while GNSS plays an important role in disaster relief and rescue. However, when ground surface is severely damaged covered, satellite positioning means are denied. In addition, site conditions often very complex may require unmanned robots such as UAVs for pre-surveying. To address raised problem, we reconstructed 3D scen...

Belief propagation is a powerful procedure to perform inference, and exhibits near-optimal performance in iterative decoding/demapping. However, a complete analysis of the iterative process is still lacking, and convergence of the procedure has not proved in general cases. Information geometry offers a new view from differential geometry to understand this problem. In this thesis, we try to und...

Recent natural disasters highlight the complexities associated with planning, coordination and distribution of supplies in a manner which provides timely and effective response. In this paper, the authors present a model to quantify the benefits associated with pre-positioning local supplies. They assume the supplies are in a high-risk location and may be destroyed if an appropriate strategy to...

Wireless sensor networks (WSN) have become increasingly popular in monitoring environments such as: disaster relief operations, seismic data collection, monitoring wildlife and military intelligence. The sensor typically consists of small, inexpensive, battery-powered sensing devices fitted with wireless transmitters, which can be spatially scattered to form an ad hoc hierarchically structured ...

Following the occurrence of unexpected events and natural disasters, a highly important relief operation is the transferring of relief commodities from the distribution centers (CDs) to shelters. In this paper, a three-level network consisting of depot of vehicles, distribution centers and shelters has been considered for routing and scheduling of relief vehicles through introducing a multi-obj...

Enabling the positioning of cellular handsets increases the safety level and at the same time opens exciting commercial opportunities for operators through providing location-based services. A major implementation obstacle, which prevents a wide deployment of cellular location techniques is the requirement of modifications of the existing network infrastructures and a need for the replacement o...
