This paper is concerned with application and evaluation of ant colony optimization (ACO) method to practical structural optimization problems. In particular, a size optimum design of pin-jointed truss structures is considered with ACO such that the members are chosen from ready sections for minimum weight design. The application of the algorithm is demonstrated using two design examples with pr...

Ergonomics is a vital consideration for space design. In architecture education, ergonomics usually taught in the design studio with various learning methods such as lecture, demonstration, survey, exercise etc. This article presents an anthropometric study through dedicated to ergonomic considerations. It dataset prepared within designing lavatory and kitchen spaces. Bangladesh, there scarcity...

Bituminous mix design is a delicate balancing act between the proportions of aggregate sizes and bitumen content. For a given aggregate gradation, the optimum bitumen content is estimated by satisfying a number of mix design parameters recommended in the specifications. In this paper, some of new considerations related to the bituminous mix design are discussed. Bituminous mix design, with thes...

nowadays, numerous realities in the field of architecture has gathered architects’ concentration; this has alienated designer’s attention from theoretical thinking in the initial stages of design process. new considerations such as human attitude and orientation in urban areas, the environmental impacts, behavioral relations between man and building, considering sociology and psychology in crea...

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...
