A polypropylene microporous membrane (PPMM) was fabricated by thermally induced phase separation (TIPS) method. The effects of protein size and structure as well as filtration pressure on the membrane performance and fouling mechanisms were investigated using two different proteins, bovine serum albumin (BSA) and collagen, in dead-end filtration setup. Obtained results showed that, for each pro...

Abstract Classical dynamic balancing techniques do not consider the linkage elastic behavior. For mechanism or robot design purpose, taking into account flexibility of multibody system is utmost importance, in order to be able manufacture a mechanism/robot which stiff enough for given task. This paper deals with novel approach that allows mechanisms by means structural topology optimization whi...

Reentrant processing has been proposed as a critical mechanism in feature binding. To test this claim, participants were shown arrays of six pairs of crossed vertical and horizontal bars. In each pair, one bar was white; one was red, green, or blue. Identifying the orientation, but not the color, of the nonwhite bar in the target item required correct binding. Four dots appeared around one of t...

Designing a movable spatial four-bar mechanism that guides a coupler system through three given poses is an old and well known problem. The resulting mechanism has to be overconstrained and is called Bennett mechanism. We give a completely new solution of this problem using kinematic mapping and multidimensional geometry. This approach provides a new insight in the problem. First of all it show...

2 Sustainable and Infrastructure Research and Development Center, Department of Mechanical Engineering, Faculty of Engineering, KhonKaen University, KhonKaen City, Thailand ABSTRACT: This paper presents the optimization of path generating of four-bar linkages using evolution algorithms (EAs). The design problem is assigned to minimize the error between desired and obtained coupler curves. Such ...

Geared Five-bar motion generation is used to synthesize a mechanism which passes through or approximate prescribed rigid-body positions. This work will discuss the motion generation of geared five-bar mechanism with position tolerance variations due to gear fabrication. The tolerance variations study will be based on the standards of American Gear Manufacturing Association (AGMA) and American N...
