in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
An image or a pattern can be recognized using prior knowledge or the statistical informa‐ tion extracted from the image or the pattern. The systems for image recognition and classifi‐ cation have diverse applications, e.g. autonomous robot navigation[1], image tracking radar [2], face recognition [3], biometrics [4], intelligent transportation, license plate recognition, character recognition [...
Transportation is one of the most important issues in today's cities. Urban trips and their spatial and temporal patterns influence and are influenced by other components and functions of the city. Information and communication technology have evolved rapidly over the last few decades and have influenced urban travel patterns in many ways. Numerous studies have attempted to study the effects of...
This paper constructs a theoretical model, in which transportation costs between two locations depend on cumulative infrastructure investment and governments allocate infrastructure spending over continuous space, thereby affecting the geographical pattern of transportation costs. Modelling international trade, we assume that governments set their infrastructure investment schedules in a non-co...
Contemporary urban areas are complex economic and transportation systems having a structured land use pattern. The utility value of land use is a measurement unit of the value of a specific land use zone in relation to the whole economic system. It is the effective economic output value of land use and it is defined according to concepts of accessibility level, economic level and spatial intera...
OBJECTIVE To study the differential distribution of transportation injury mortality by educational level in nine European settings, among people older than 30 years, during the 1990s. METHODS Deaths of men and women older than 30 years from transportation injuries were studied. Rate differences and rate ratios (RR) between high and low educational level rates were obtained. RESULTS Among me...
Root canal preparation is an important step in endodontic treatment. The anatomical complexity of the middle third of the root compromises the effective cleaning of this area. Thus, advances have been made in instrumentation techniques and instruments for this purpose. The aim of this study was to evaluate the effects of three different instrumentation systems on the enlargement of the middle t...
In order to solve the problems of mismatch between transportation resources and volume in logistics transportation, we propose a cooperative pattern called sharing this problems. pattern, several enterprises or alliances cooperate with each other share achieve goal reducing costs increasing income. paper, set application scene section from distribution center service outlets city. We first put ...
