An optimization approach to wastewater systems planning at regional level

An Efficient Simulated Annealing Algorithm for Regional Wastewater System Planning

At present, most wastewater systems are local, i.e., each city has its own system. However, in many cases, they could be better, both from the economic and the environmental viewpoints, if they were regional. The search for the best regional wastewater systems can only be effective if it is made through an optimization model. In this article, we report a study made to develop an efficient simul...

An Optimization-Based Approach for Locomotive Planning

An Optimization Approach for Radiosurgery Treatment Planning

We outline a new approach for radiosurgery treatment planning, based on solving a series of optimization problems. We consider a specific treatment planning problem for a specialized device known as the Gamma Knife, that provides an advanced stereotactic approach to the treatment of tumors, vascular malformations, and pain disorders within the head. The sequence of optimization problems involve...

An Investigation of Global-Regional Interactional Approach at the Prominent Works of Contemporary Iranian Architects

Regionalism is an analytical and critical perspective which focuses on preserving special features of place and attempts to fill the vacuum in architecture. Globalization is a complex multi-stage process that causes increasing complexity of time and place, greater awareness across the global and acceleration of cross cultural interactions. Therefore, the present paper attempts to analyze global...

An Approach to Reducing Overfitting in FCM with Evolutionary Optimization

Fuzzy clustering methods are conveniently employed in constructing a fuzzy model of a system, but they need to tune some parameters. In this research, FCM is chosen for fuzzy clustering. Parameters such as the number of clusters and the value of fuzzifier significantly influence the extent of generalization of the fuzzy model. These two parameters require tuning to reduce the overfitting in the...
