This paper proposes an effective algorithm based on the level set method (LSM) to solve shape and topology optimization problems. Since the conventional LSM has several limitations, a binary level set method (BLSM) is used instead. In the BLSM, the level set function can only take 1 and -1 values at convergence. Thus, it is related to phase-field methods. We don’t need to solve the Hamilton-Jac...

This work presents a method for optimum design of structures, where the design variables can he considered as Continuous or discrete. The variables are chosen as sizing variables as well as coordinates of joints. The main idea is to reduce the number of structural analyses and the overal cost of optimization. In each design cycle, first the structural response quantities such as forces, displac...

A bi-level model for traffic signal optimization is developed. The predictive framework applied control in an urban network. potential of the formalization used to increase space influences with simultaneous evaluation green light and cycle durations. Thus, increased allows more parameters be considered, such as vehicles queues flows. particular modification synchronization lights approach real...
