One of the key activities during disaster response is distributing relief items to victims. This a challenging task due dynamically changing victim needs and aftermath conditions. We model distribution operations where like tarpaulins blankets are distributed by volunteers, victims at temporary areas called centers (RC). investigate impact movements have on performance. each RC as queue, operat...

To increase reliability and robustness of mission-critical services in the event of network failures, it is often desirable and beneficial to take advantage of path diversity provided by the network topology. One way of achieving this inside a single Autonomous System (AS) is to use two paths between every Origin-Destination (OD) pair. One path is the default path defined by the intra-domain ro...

Generic indoor personal positioning with an accuracy better than 10m error is still a challenging research issue. It is well known that the key to solving this problem is the combination of different positioning techniques. In this paper, a combined approach of pedestrian dead reckoning (PDR) and GPS positioning is followed. An acceleration sensor provides signals with which a neural network is...

This paper studies the topological properties of dynamics industry indices network at Moroccan stock exchange by using theory. The Minimum Spanning Tree (MST) was constructed from metric distances which had been calculated for different pairs industrial indices. MST were analysed over period 2013 to 2020 sliding window technique. studied divided into pre-pandemic Covid-19 and pandemic period. C...

Position information is often one of the key requirements for a wireless sensor network (WSN) to function as intended. Due to drawbacks in using GPS or having to manually setting sensor positions, extracting the position information by means of the network itself has been extensively studied in the literature. In this approach, it is commonly assumed that there are a few sensor nodes with known...

Political elite’s relations for maintaining power is an important key to analyse the government’s behaviour. This paper presents a new network policy among the Iranian political elite using Social Network Analysis Method. How do they make the network? Is there Elite to Elite family relation based on ideological united or common interests? Network boundary is the political elites who have kinshi...

In this paper, we address a two-echelon humanitarian logistics network design problem involving multiple central warehouses (CWs) and local distribution centers (LDCs) and develop a novel two-stage scenariobased possibilistic-stochastic programming (SBPSP) approach. The research is motivated by the urgent need for designing a relief network in Tehran in preparation for potential earthquakes to ...

This paper investigates a Global Positioning system (GPS)-free positioning method for mobile units (MUs) in outdoor wireless environments by using the Bayesian filtering formulation. The procedure utilizes simulated inertial measurements, cell-ID of the serving base station, and pre-determined locations grouped according to cell antennas radio coverage in the experimentation area. The developed...

Problem statement: Location knowledge in indoor environment using Indoor Positioning Systems (IPS) has become very useful and popular in recent years. A number of Location Based Services (LBS) have been developed, which are based on IPS, these LBS include asset tracking, inventory management and security based applications. Many next-generation LBS applications such as social networking, local ...
