In recent years, the value-added created in the transportation industry is about 8 percent of GDP of Iran. Due to the high-induced effect of transportation sector on the whole economy, analyzing transportation production function and its determinant is of great value for policymakers. The objective of the present research is to estimate the transportation production for the case of Iran and to ...

background and goal: burn is an irreparable event, which results in numerous physical, psychological, social, and economic complications. the burned patients should be merely treated in a professional burn center due to vast clinical range of these patients. since, a percentage of mortality in burned patients is for the patients’ transportation from other centers; this study has aimed to invest...

This thesis extends the previous literature on urban subcenter formation by introducing congestion cost of transportation. A new model is constructed to analyze the efficiency of private decision about firm decentralization with the presence of unpriced transportation congestion. The model features a linear city with provision of transportation infrastructure oriented toward carrying workers to...

This project involves a comprehensive generalizable and transferable evaluation of the Courseware Development Project (CDP) at Dalhousie University's School of Business Administration. This C$3 million, three-year project is divided into four levels over three time phases. The results of the study of the impact of this unique project are expected to be both relevant and applicable to other univ...

An important component of the drive towards intelligent vehicles is the ability to maintain a xed distance from a lead vehicle using feedback provided by range sensors. We are investigating the possibility of using stereo vision to provide the range information, in conjunction with a scanning laser radar sensor. The vision algorithms build on xation and reconstruction algorithms designed for ac...

The Baltic Sea shipping is at a crossroads as sulphur regulation will lead to excessive cost increases from the year 2015 onwards and CO2 emission trading is planned to be implemented for the entire shipping sector within the EU area. Therefore, shipping is going to be minimized and hinterland transportation (road and rail) will act as substitute. This research analyzes the situation on one of ...

Sustainability throughout supply chains is gaining more importance and re-planning inventory operations can help companies curb emissions. In this study, we present two bi-objective integrated continuous review inventory control and transportation models with less-than-truckload and truckload carriers. Solution methods to approximate the Pareto Frontiers are proposed. Numerical studies illustra...

This paper investigates geometric and algorithmic properties of the Voronoi diagram with a transportation network on the Euclidean plane. With a transportation network, the distance is measured as the length of the shortest (time) path. In doing so, we introduce a needle, a generalized Voronoi site. We present an O(nm + m + nm log n) algorithm to compute the Voronoi diagram with a transportatio...
