We consider an optimization problem on the maximal magnitude of angular acceleration output-links a commercially available center-driven linkage system (CDLS) for vehicle wipers windshield. The purpose this is to improve steadiness without weakening its normal function. Thus considered under assumptions that frame fixed links unchanged and input-link rotates at same constant speed with length u...

Because the electrical installations are nowadays a lot of options and variants, it is necessary to evaluate these complex installation process from several perspectives and objectively. Due to the complexity of evaluation of electrical installation is design a methodology that uses multi-criteria analysis MCA.

In order to manage site precast concrete construction which has been increasing, an integrated construction management system employing a unique 3-D modelling method and analogue process input method was developed. At the planning stage, the system supports interactive planning between member configuration and installation planning by a visual method and with an accurate quantity. At the proces...
