Introduction: Appropriate definition of the distance measure between diffusion tensors has a deep impact on Diffusion Tensor Image (DTI) segmentation results. The geodesic metric is the best distance measure since it yields high-quality segmentation results. However, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. The main goal of this ...

vehicle routing problem (vrp) is one of the major problems in the transportation and distribution planning. in the most previous studies, the objective of vrp models was distance and vehicle related costs. however in many industrial cases along with routing distance, vehicle loading amount is a factor of cost function. in this paper, we formulate a mixed integer non-linear programming (minlp) m...

A new model and solution for the energy minimizing vehicle routing problem with time windows (EVRPTW) and customers’ priority is presented in this paper. In this paper unlike prior attempts to minimize cost by minimizing overall traveling distance, the model also incorporates energy minimizing which meets the latest requirements of green logistics. This paper includes the vehicles load as an ad...

This study was on the analysis of livestock waste management practices among rural farmers in Abia State, Nigeria. A multi-stage sampling procedure was employed to select the 60 respondents for the study. Primary data used the study were collected using well-structured questionnaire. Descriptive statistical tools such as frequency counts, percentages, means, and multinomial logit regression wer...

A p-hub center network design problem is definition of some nodes as hubs and allocation of non-hub nodes to them wherein the maximum travel times between any pair of nodes is minimized. The distinctive feature of this study is proposing a new mathematical formulation for modeling costs in a p-hub center problem. Here, instead of considering costs as a linear function of distance, for the first...

Tree edit distance is a conventional dissimilarity measure between labeled trees. However, tree edit distance including unit-cost edit distance contains the similarity of label and that of tree structure simultaneously. Therefore, even if the label similarity between two trees that share many nodes with the same label is high, the high label similarity is hard to be recognized from their tree e...

Stochastic complexity (SC) has been employed as a cost function for solving binary clustering problem using Shannon code length (CL distance) as the distance function. The CL distance, however, is defined for a given static clustering only, and it does not take into account of the changes in the class distribution during the clustering process. We propose a new DSC distance function, which is d...

magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...
