In order to achieve the synthesis of contracted graphs (CGs) automatically by given associated linkages (ALs), a new feature description method is proposed and software constructed. First all, connection substring (CMS) related guidelines are given. The combination characteristic strings (CSs) CMSs can accurately describe type, number, relationship between basic links in CG. Secondly, computer ...

Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking.  Methods: This is a quasi-experimental study...

Abstract The human earcanal can accommodate several types of in-ear devices including hearing aids, earphones, protectors, and earplugs. This canal-type home has a neighbor called the temporomandibular joint (TMJ) whose movements slightly deform shape earcanal. While these cyclic deformations influence positioning, comfort, functioning ear-fitted devices, they also provide significant amount en...

The genetic algorithm is implemented to solve the problem of accuracy synthesis for a 3-UCR (UniversalCylindrical-Revolute) parallel robot. Accuracy synthesis is one challenging topic for the parallel robot in the precision applications. First, the kinematic model and error model are built for the 3-UCR parallel robot. Then, the accuracy synthesis model based on manufacturing cost is formulated...
