Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

This paper presents techniques of integrating haptic device into computer-aided design and manufacturing. The methodology is proposed as three steps: 1) develop the virtual sculpting system for aiding product design; 2) convert the product design into acceptable form for downstream manufacturing or rapid prototyping; 3) develop multi-axis polyhedral machining planning system with haptic input. ...

Computer-aided process planning has been recognized as an important tool for coordinating the different operations involved in making the product. While temporal knowledge is central to the design of efficient and reliable process plans, little attention is given to the integration of process planning and temporal processing and reasoning. To fill the void, we propose in this paper a practical ...

Computer-aided process planning represents the main link between computer-aided design and manufacturing. One of crucial tasks in is an operation sequencing problem. In order to find optimal plan, problem formulated as NP hard combinatorial To solve this problem, a novel genetic crow search approach (GCSA) proposed paper. The traditional CSA improved by employing strategies such tournament sele...
