it is accepted that the visual comfort in schools depends on the quality of the whole visual environment. this leads to the concern upon the quality and quantity of lighting. currently in iran, in order to calculate energy transfer for public buildings a coefficient is usually used. this coefficient considers the rate of sunlight energy absorption in these kinds of buildings. to increase the de...

current practices in railway track analysis and design are reviewed and discussed in this paper. the mechanical behavior of railway track structure comprising of various components has not been fully understood due to the railway track structural complexity. although there have been some improvements in the accuracy of current track design methods in recent decades, there are still considerable...

Many real-world search and optimization problems involve inequality and/or equality constraints and are thus posed as constrained optimization problems. In trying to solve constrained optimization problems using classical optimization methods, this paper presents a Multi-Objective Bees Algorithm (MOBA) for solving the multi-objective optimal of mechanical engineering problems design. In the pre...
