Prediction models for conflict rate in unsignalized intersections
Most conflicts occurring in intersections are related to left turn of vehicles. Therefore, transportation engineers use access management as an effective tool to improve arterial ways safety specifications to solve the problem and minimize conflicts. The goal of this study is offering prediction models for conflicts in unsignalized intersection for direct left turn (DLT). In other words, these models analyze...

Investigating effect of size element in nonlinear behavior of concrete shear wall
Completion and development of reliable analytical models using finite element method could help investigation and prediction of the actual structure response results. Analysis of each model in finite element software need meshing that computer results are dependent specific to geometry and dimensions of the elements, calling mesh dependence. Finding a strategy for independency of results to meshing is...

Multi-objective optimization of a spouted bed via Genetic algorithm
Performance of the gas-solid spouted bed benefits from solid's uniformity structure (UI) with lower pressure drop (PD). Spouted bed system needs to be optimized to achieve the maximum performance. Therefore; the focus of this work is to maximize the UI and to minimize the PD along the bed. Three selected decision variables are affecting these objectives that are; gas' velocity, particle's density...
