Force-closure workspace analysis of cable-driven parallel mechanisms

Cong Bang Pham, Song Huat Yeo, Guilin Yang, Mustafa Shabbir Kurbanhusen, I-Ming Chen
2006 Mechanism and Machine Theory  
This paper focuses on the workspace analysis of fully restrained positioning mechanisms.  ...  To simplify the analysis, a recursive dimension reduction algorithm is proposed to check convex hulls in one dimension spaces. This algorithm is verified through simulation results of various CDPMs.  ...  Here, the research is focused on fully restrained CDPMs (m P n + 1). A general recursive approach is proposed to check the force-closure condition.  ...

Selection from read-only memory with limited workspace [article]

Amr Elmasry and Daniel Dahl Juhl and Jyrki Katajainen and Srinivasa Rao Satti
2014 arXiv   pre-print
We also generalize our algorithm for the case when the size of the workspace is Θ(S) bits, where ^3N≤ S ≤ N.  ...  We study the complexity of this problem in the space-restricted random-access model: The input array is stored on read-only memory, and the algorithm has access to a limited amount of workspace.  ...  When t is a constant, the maximum depth of the recursion stack is O(lg N ). Thus, the overall workspace used is O(lg 2 N ) bits.  ...

RECSY – A High Performance Library for Sylvester-Type Matrix Equations [chapter]

Isak Jonsson, Bo Kågström
2003 Lecture Notes in Computer Science  
In order to achieve these goals, RECSY is based on novel recursive blocked algorithms, which call high-performance kernels for solving small-sized leaf problems of the recursion tree.  ...  The performance improvements of our recursive algorithms are remarkable, including 10-fold speedups compared to standard algorithms.  ...  Second, if there are more than two processors in the system, the OpenMP compiler must support nested parallelism in order to fully utilize the system, which most modern OpenMP compilers do.  ...

These operations support creating, updating, combining, and comparing contexts.  ...  Although semantic data models provide expressive conceptual modeling mechanisms, they do not support context, i.e. providing controlled partial information on conceptual entities by viewing them from different  ...  In a cooperation environment, there are three basic workspaces: public, group, and private. The public workspace contains fully verified object versions.  ...

Integral-C---a practical environment for C programming

Graham Ross
1987 SIGPLAN notices  
Debugging support code is written in C in a 'workspace', which grants it direct access to a local scope while keeping it separate from the client program. -  ...  For more complex jobs, a special purpose workspace can be built. Other Windows The workspace browser is an editor for code that supports debugging. It is fully described in a later section.  ...  It displays values for automatically allocated data objects, which may appear recursively.  ...

Kinematics and Dynamics of an Asymmetrical Parallel Robotic Wrist

Guanglei Wu
2014 Journal of Robotics  
The recursive Newton-Euler method consists of two steps: the first step is an outward recursion to calculate velocity and acceleration from the base to the end link; the second step is an inward recursion  ...  Through a U-joint, the decoupled rotation of the inner ringer is driven by the center shaft that supports the MP to improve the positioning accuracy.  ...

Palantir: raising awareness among configuration management workspaces

A. Sarma, Z. Noroozi, A. van der Hoek
2003 25th International Conference on Software Engineering, 2003. Proceedings.  
To fill this void, we have developed Palantír, a novel workspace awareness tool that complements existing configuration management systems by providing developers with insight into other workspaces.  ...  Current configuration management systems promote workspaces that isolate developers from each other. This isolation is both good and bad.  ...  This research is supported by the National Science Foundation under Grant Number CCR-0093489.  ...

Reconciling software configuration management and product data management

Jacky Estublier, German Vega
2007 Proceedings of the the 6th joint meeting of the European software engineering conference and the ACM SIGSOFT symposium on The foundations of software engineering - ESEC-FSE '07  
PDM is good at modeling while SCM is good at building and supporting concurrent engineering.  ...  From a software engineering perspective, the challenge is to take the full potential of strong modeling capabilities, while preserving good concurrent engineering support.  ...  The experience of using workspace alone is compelling, and fully supports the claims from the product engineering community.  ...
