The current research investigated the coupling effect of blockage and tunnel slope on spreading characteristics fire smoke ceiling temperature distribution in a metro depot with one closed end. A series 1/15 reduced scale experiments full-scale numerical simulations were conducted to capture global characteristics. investigation addressed compared plume behavior both uphill downhill situations....

in this paper, we study the multi-depot vehiclerouting problem with inter-depot routes, in which the vehicles can replenish atintermediate depots. vehicles leave the origin depot with load on-board andserve customers until out of load. they may visit an intermediate depot toreplenish and finally return to the origin depot, completing their route. weinitiate a mathematical mixed integer programm...

in the recent decade, special attention is paid to reverse logistic due to economic benefits of recovery and recycling of used products as well as environmental legislation and social concerns. on the other hand، many researches claim that separately and sequential planning of forward and reverse logistic causes sub-optimality. effective transport activities are also one of the most important c...

Cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. During such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. Therefore, to design and dev...

The purpose of this paper is to present new methods for solving the vehicle routing problem with time windows (VRPTW). VRPTW can be described as the problem of designing least cost routes from one depot to a set of geographically scattered points. The routes must be designed in such a way that each point is visited only once by exactly one vehicle within a given time interval; all routes start ...

The fatty acid Composition of lipids from erythrocytes and depot fat of rats whose diet wac supplemented with various levels of linoleate, arachidonate, or linolenate has been investigated. Dietary linoleate and linolenate are incorporated into the depot fat. The ratio of eicosatrienoic acid to eicosatetraenoic acid, derived from the analysis of depot fat, decreases with increasing amounts of a...

In this work, the capacitated location-routing problem with simultaneous pickup and delivery (CLRP-SPD) is considered. This problem is a more realistic case of the capacitated location-routing problem (CLRP) and belongs to the reverse logistics of the supply chain. The problem has many real-life applications of which some have been addressed in the literature such as management of liquid petrol...

This paper considers stochastic load-constrained vehicle routing systems in which a fleet of homogeneous vehicles is dispatched from a central depot to serve the demands of surrounding customers. Customer locations and load sizes are known only in distribution before operations. Variants of this problem are often treated with very simple uncoordinated operating schemes, which are mathematically...

In recent years, there has been a great deal of research in developing end-to-end speech recognition models, which enable simplifying the traditional pipeline and achieving promising results. Despite their remarkable performance improvements, models typically require expensive computational cost to show successful performance. To reduce this burden, knowledge distillation (KD), is popular model...
