Emergencies, especially major ones, happen fast, randomly, as well as unpredictably, and generally will bring great harm to people's life and the economy. Therefore, governments and lots of professionals devote themselves to taking effective measures and providing optimal evacuation plans. This paper establishes two different emergency evacuation models on the basis of the maximum flow model (M...

Communication networks are nowadays crucial in our lives and the study of its traffic features yields important advantages. In both network and traffic design the understanding of the relationship between the traffic on a node and its fluctuations plays a key role. In this paper we investigate the relationship between the mean traffic flow experienced by a node and its standard deviation via nu...

This paper proposes a backward/forward sweep method to analyze the power flow in radial distribution systems. The distribution system has radial structure and high R/X ratios. So the newton-raphson and fast decoupled methods are failed with distribution system. The proposed method presents a load flow study using backward/forward sweep method, which is one of the most effective methods for the ...

It is a major scientific theoretical significance and practical value that the identification of the hub node in the transport network. This paper presents a new method which can detect the hub node of the urban transportation based on the idea of local modularity measure. Evaluation indicators include node degree, clustering coefficient, peak hour traffic flow. First, apply a complex network o...

Background & Objectives: Colon cancer is currently of high incidence and mortality rate. Identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. Recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor. The aim of the present study is to investigate the effect of this factor on the prognosis of the ...

This paper provides the implementation mechanism of the pmipv6-based partially distributed mobility management (DMM) and performs extensive simulations under various traffic environments for verification and evaluation of the proposed scheme. The simulation results indicated that Mobility Anchor and Access Router (MAAR) could distribute and manage all IP data packet flow between a corresponding...

Control dependence forms the basis for many program analyses, such as program slicing. Recent work on control dependence analysis has led to new definitions of dependence that can cater for reactive programs with their necessarily non–terminating computations. One important such definition is the definition of Weak Order Dependence, which was introduced to generalize classical control dependenc...

Graphs provide natural and convenient representations of communication networks. Graph models and flow formulations have been extensively used in the study of a large number of issues relating to network analysis and design. Structural characteristics such as connectivity/fault survivability (a measure of robustness of networks when link or node failures occur) and diameter (a measure of delay ...

Reliability analysis is an important issue in wireless sensor networks (WSNs). This paper aims to study the reliability of a data flow in event-driven wireless sensor networks with multiple sending transmission approach without acknowledgments. Initially, an event-driven wireless sensor network model is described in terms of limited node battery energy and shadowed fading channels. Then, in ord...
