We propose a new stochastic modeling approach for a pre-disaster relief network design problem under uncertain demand and transportation capacities. We determine the size and the location of the response facilities and the inventory levels of relief supplies at each facility with the goal of guaranteeing a certain level of network reliability. The overall objective is to enhance the effectivene...

In the study, embedded BASIC Stamp 2 (BS2) microchip controller is used to design with Hopfield neural network (HNN) as the foundation of sample training, which applies for a soldering platform of mechanical vision and accomplishes PCB soldering positioning technology. The proposed system design method in this paper can be divided into two parts: 1) the control rules of RC servo motor is design...

Improved responsiveness to natural and man-made disasters is critical to saving lives and alleviating the suffering caused by such disasters. Emphasis on the design of the relief chain to reduce delivery time of relief inventory improves responsiveness. This is the essence of inventory pre-positioning (IPP). IPP is yet to be clearly defined; and the main factors affecting IPP decision-making ne...

In this paper, we present an easy method for automatic 3D garment pre-positioning. Given a digital 3D mannequin and a set of 2D patterns, the problem consists in sewing automatically the patterns around the mannequin and give an initial position of the garment that the mannequin has to wear. Our method is based upon the use of a figurine. A figurine of a virtual garment, which is always present...

Road accidents, as one of the causes mortality in human societies, have many adverse social and economic consequences. Various measures can improve safety travel. One them is to find appropriate location relief infrastructures. The proper pre-positioning chains locations  decrease road users’ fatalities. Thus this paper presents a  multi-objective mathematical model a chain for accidents. Then ...

A temporo-spatial stochastic model is formulated for analysing the problem of positioning of humanitarian relief centres for optimum disaster-relief management. Disasters occur in a line segment region of the real line according to a Poisson process. Two relief centres are positioned at two different points of the line segment for providing humanitarian relief to the disaster sites. The station...

Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...

rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. among different techniques, rss-based  schemes and in particular oneof its variants which is based on graph-based semi-supervised learning (g-ssl) are widely-used approaches the superiority of this scheme is that it has low setup/training cost and at the same ti...
