Network coding is known to provide increased throughput and reduced delay for networked communications. In this paper we propose a peer-to-peer media streaming system that exploits network coding in order to achieve low start-up delay, high streaming rate, and high resiliency to peers’ and network dynamics, such as ungraceful peer departures, and delays or packet losses. To achieve this objecti...

The logistical efficiency and viability of the algorithms in comparison with linear programrural transportation system is a growing conming for solution of models with a network cern of agricultural producers, transportation structure. Fuller et al. [4] used a network flow regulators, and policy makers. Railroad facility model in combination with implicit enumeralimitations, abandonment of rail...

Supply chain network design in perishable product has become a challenging task due to its short life time, spoilage of product in degradation nature and stochastic market demand. This paper focused on designing and optimizing model for perishable product in stochastic demand, which comprises multiple levels from producer, local collector, wholesaler and retailers. The ultimate goal is to optim...

The systems in which information and communication technologies and systems engineering concepts are utilized to develop and improve transportation systems of all kinds are called “The Intelligent Transportation Systems (ITS)”. ITS integrates information, communications, computers and other technologies and uses them in the field of transportation to build an integrated system of people, roads ...

Objective: To improve the reliability of complex urban public transportation network. Methods: Establishing the reliability evaluation system of urban public transportation network. Process: The paper introduces the development of urban traffic construction, describes the characteristic parameters of complex networks, and establishes the model of the reliability evaluation index system of compl...

In this paper, we demonstrate how to capture the robustness of a transportation network in the case of degradable links represented by decreasing capacities. In particular, with the use of Bureau of Public Road user link travel cost functions, we propose two relative total cost indices to assess transportation network robustness in the case of travel behavior associated with either user-optimiz...

conclusions components of social support, totally account for 19% of resiliency variance value of patient; the components of social support, family, friends, and other people’s support at only had lower contribution in predicting resiliency. support of this group of people to increase their resiliency seems necessary. results there was a significant association between social support and resili...

The objective of this project was to develop a structural index for use in network-level pavement evaluation to facilitate the inclusion of the pavement’s structural condition in pavement management applications. The primary goal of network-level pavement management is to provide the best service to the users for the available, often limited, resources. Pavement condition can be described in te...

Growing global demand for energy, result in depletion of easily access source of fossil fuels. To fulfillment of this huge demand, oil and gas industry expanded to develop offshore oil and gas reservoirs in recent years, which made environmental management challenging. IRAN owns one of the biggest offshore gas reservoir in PERSIAN GULF with high geopolitical and financial importance. Along the ...
