Kinematic modeling and optimization of a new reconfigurable parallel mechanism [PDF]

Mechanism and Machine Theory, 2020
This paper investigates a new reconfigurable parallel mechanism consisting of three SvPS kinematic limbs. Induced by phase changes of a metamorphic spherical variable-axis joint (Sv), the SvPS limb is capable of changing to two typical configurations, of

Constraint singularities of parallel mechanisms

Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003
The concept of constraint singularity is introduced. This is a phenomenon occurring in parallel mechanisms with reduced freedoms when the screw system, formed by the constraint wrenches in all legs, loses rank.

A Parallel Mechanism for Describing Silhouettes

IEEE Transactions on Computers, 1972
We describe a parallel mechanism, based on an array of circularly nutating photodetectors, that computes an approximation of the density of slopes of the boundary of any piecewise regular silhouette. This density, when properly normalized, is invariant with respect to the size, translation, and orientation of the given silhouette.

A Parallel Computer Organization and Mechanizations

IEEE Transactions on Electronic Computers, 1963
This paper describes a type of parallel computer organization which can be regarded as lying at one extreme of a spectrum of possible degrees of parallelism. The organization is dominated by two characteristics, namely, one-bit storage per computational cell and single-level logic at each computational step.

Parallel replacement mechanism for multithread

Proceedings. Advances in Parallel and Distributed Computing, 2002
This paper presents a new rapid thread replacement mechanism which is important in multithread technology. Analysis to the memory system indicates that the memory utilization decreases with the increase of cache hit ratio. The parallelism between thread computation and thread replacement is found by analyzing their working processes. Based on these, we
