there are some problems with estimating the time required for the manufacturing process of products, especially when there is a variable serving time, like control stage. these problems will cause overestimation of process time. layout constraints, reworking constraints and inflexible product schedule in multi product lines need a precise planning to reduce volume in particular situation of lin...

Soft actuators are receiving increasing attention from the engineering community, not only in research but even for industrial applications. Among soft actuators, fibre-reinforced Bending Fluidic Actuators (BFAs) became very popular thanks to features such as robustness and easy design and fabrication. However, an accurate modelling of these smart structures, taking into account all the nonline...

This paper develops an efficient, physically based shape manipulation technique. It defines a 3D model with profile curves, and uses spine curves generated from the profile curves to control the motion and global shape of 3D models. Profile and spine curves are changed into profile and spine wires by specifying proper material and geometric properties together with external forces. The underlyi...

This work concerns an assessment of the behavior of infilled frames. The feasibility of possible immediate implementation of some recent developments both in analysis and design of infilled frames for practical design is investigated. It is now widely recognized that masonry infill panels used in reinforced concrete (R/C) frame structures, significantly enhance both the stiffness and the streng...

In recent years, glass-fiber reinforced composite materials are more and more used in structural applications. Their mechanical properties: low density, high strength and high chemical corrosionresistance offer an interesting alternative solution to metallic or concrete material. The pultrusion is a composite material processing technique that is penetrating the civil engineering market since t...

Let G be a finite group generated by reflections. It is shown that the elements of G can be arranged in a cycle (a "Gray. code") such that each element is obtained from the previous one by applying one of the generators. The case G = d[ ' yields a conventional binary Gray code. These generalized Gray codes provide an efficient wa), to run through the elements of any finite reflection group.

In the field of materials engineering, various types advanced have been found. This must also be accompanied by technological advances in production process. Centrifugal casting is an effective method for cylindrical objects such as pipes and pressure vessels. this research, a centrifugal machine designed made. The design process follows steps proposed Pahl Beitz, starting from requirements ide...
