This paper describes a multimodal transportation network (MTN) in which several unimodal networks (AGVs, hoists, lifts, suspended monorail systems, etc.) interact each other via common shared workstations as to provide a variety of demand-responsive workpiece transportation/handling services. The set of transport modes provides connection support for production flows treated as agents trying to...

Introduction: In only two meteorites, Krymka and Supuhee, a very rare, fine-grained mysterious material has been discovered so far. Laul et al. [1] detected in these two ordinary chondrites an enrichment in Ag, Tl, and Bi. They concluded that this enrichment has its origin in a late condensate introduced during a brecciation event. Since a petrographic carrier of the volatiles could not be spec...

Background. Much of the sedimentary transport and depositional history of Mars may be recorded in the morphologic characteristics of the individual rocks or particles that make up its sedimentary clast population (defined as a rock fragment or grain resulting from the breakdown of larger rocks or bedrock). Measuring morphology is crucial; it retains the best record of sorting and abrasive effec...

condensing flows in nozzles and fixed blades of steam turbine have always been the subject of many studies.in such flows, existence of liquid phase in vapor changes the nature of the flow. the major of changes are due to four main mechanisms included nucleation, droplet growth, coalescence and breakage of droplets. in this paper,the effects of coalescence process between droplets have been inve...

An array of noteworthy developments in logistics practice has taken place without an equivalent and comprehensive development in urban freight transportation modeling. Part of the problem is the lack of deep understanding of the workings of distribution processes in relation to the generation of truck traffic. In this paper it is emphasized the role and importance that distribution network size...

I nrecent years there has been a noticeable shift away from the application of computer-based transportation modeling methods in smallto medium-sized urban areas. In many cases, this shift has resulted from a disenchantment with the complex modeling methodologies used in the late 1960s and early 1970s. The expense of such methods, in terms of data collection and computational costs, was simply ...

Aghajari Formation, known as Upper Fars Group, is developed throughout the Folded Zagros Zone and has a thickness of 2966 m in its type section in SW of Iran and 1473 m in the study area, located 20 km west of Shiraz. Aghajari Formation, in this area, consists of three major facies associations. These are "fine", "medium" and "coarse" grained terrigenous sediments, usually interpreted as channe...

Understanding network flows such as commuter traffic in large transportation networks is an ongoing challenge due to the complex nature of the transportation infrastructure and human mobility. Here we show a first-principles based method for traffic prediction using a cost-based generalization of the radiation model for human mobility, coupled with a cost-minimizing algorithm for efficient dist...

Guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of Intelligent Transportation Systems (ITS). Nowadays, many complex systems can be controlled by using multi agent systems. Adaptation with the current condition is an important feature of the agents. In this research, formulation of dynamic guidance for vehicles has been investigated based...
