Cross-docking is a distribution system where products transported from warehouses to destinations are unloaded temporarily at intermediate facilities, and loaded onto outbound trucks to be shipped to their final destination. The complexity of cross-docking operations has been considered a problem of great interest to researchers and practitioners in the areas of Scheduling, Optimization, Supply...

Since the Vehicle Routing Problem (VRP) was introduced by Dantzig and Ramser, it became one of the most studied problems in Combinatorial Optimization. Different solution approaches were proposed over the past decades to solve the VRP and its variants. In this thesis, we discuss about two VRP variants, resulting from the integration of VRPs with distribution problems. The first problem takes pl...

This paper proposes an integrated network design model for a post-distribution cross-docking strategy, comprising multi product production facilities with shared production resources, capacitated cross docks with setup cost and customer zones with time windows constraints. The model is dynamic in terms of time-varying uncertain demands, whereas uncertainty is expressed with scenario approach an...

Human papillomaviruses (HPV) are a group of strong human carcinogen viruses considered to be the fourth leading cause of mortality among women in the world. HPV is the most important cause of cervical cancer, which is the second most common cancer in women living in low and middle-income countries. To date, there is no effective cure for an ongoing HPV infection; therefore, it is required to in...

microgrids are small-scale, low voltage (lv) power networks which employ renewable distribution energy resources (ders) with power electronic interfaces (peis). microgrids as single controlled units and active distribution networks require flexible control systems to ensure reliable and secure operation in different modes. these various operations of microgrid cause variations in voltage and fr...

A new model for the design of the city gas distribution network has been presented. On the basis of mass flow rates and pressure balances a nonlinear system of equation is obtained. A method for solving the latter is outlined which gives accurate results. Also, this method, when compared to the other accessible ones, takes less computer time. Finally in this method the actual length of netw...

Due to the resource constraints on sensor networks, many recent key management schemes exploit the location of nodes in order to establish pairwise keys. Despite these efforts, location discovery for sensor networks is very difficult, because existing schemes have failed to consider changes in the signal range and the deployment error. As a result, network performance may accidentally decrease,...

Introduction: Drugs are mainly delivered to the target tissues by plasma proteins, such as human serum albumin, in the human body. Practical information about the thermodynamic parameters of drugs and their stability can be obtained using simulation methods, such as molecular docking. Material & Methods: This study, investigated the molecular docking of human serum albumin with fluorouracil an...

A trusted quantum relay is introduced to enable quantum key distribution links to form the basic legs in a quantum key distribution network. The idea is based on the well-known intercept/resend eavesdropping. The same scheme can be used to make quantum key distribution between several parties. No entanglement is required.

  Objective(s): A fast and reliable evaluation of the binding energy from a single conformation of a molecular complex is an important practical task. Artificial neural networks (ANNs) are strong tools for predicting nonlinear functions which are used in this paper to predict binding energy. We proposed a structure that obtains binding energy using physicochemical molecular descripti...
