Singularity Representation and Workspace Determination of a Special Class of the Gough-Stewart Platforms

open access: yesInternational Journal of Advanced Robotic Systems, 2013
The closed-loop nature of the Gough-Stewart platform generates complex singular configurations inside the workspace and makes its workspace smaller compared to the serial mechanism.

Kinematic Analysis of a Parallel Manipulator Driven by Perpendicular Linear Actuators

open access: yesActuators, 2021
In this paper, a goniometer-type specimen stage with a linear actuation mechanism mounted on a rotation mechanism is introduced. The linear actuation mechanism was modeled as a spatial parallel manipulator consisting of a moving body, three linear ...

Workspace awareness for groupware [PDF]

open access: yesConference companion on Human factors in computing systems common ground - CHI '96, 1996
Shared physical workspaces allow people to maintain upto-the minute knowledge about others’ interaction with the workspace. This knowledge is workspace awareness, part of the glue that allows groups to collaborate effectively. In this paper, we present the concept of workspace awareness as a key for groupware systems that wish to support the fluid ...

Rethink space: (Re)designing a workspace using human-centered design to support flexibility, collaboration, and engagement among clinical and translational research support services

open access: yesJournal of Clinical and Translational Science, 2017
Introduction Space matters. We read space like we read people’s faces. Space is an instrument of collaboration and innovation. At the University of Michigan’s Institute for Clinical and Health Research (MICHR),

WS-Workspace: Workspace Versioning for Web Services [PDF]

open access: yes, 2003
When using web services to perform complex data manipulations, users and administrators need control over how their changes are managed and seen by other clients of the service. This includes support for undo of changes, batch publishing of many changes, ‘what if’ analysis, the collaboration of several people in making and approving a complex change ...

Exploring the clinical utility of liquid biopsy with cfDNA in cancer: A systematic review

open access: yesThe Journal of Liquid Biopsy
Various tumor cells may exhibit different genetic or phenotypic characteristics. This phenomenon of cancer cells, known as Tumor Heterogeneity, is responsible for multiple cancer sites caused in a single patient through metastases.

Kinematic Comparisons of Hybrid Mechanisms for Bone Surgery: 3-PRP-3-RPS and 3-RPS-3-PRP

open access: yesMachines, 2022
This paper proposes an approach to derive the Jacobian matrix of a hybrid mechanism by applying a velocity operator to the transformation matrix. This Jacobian matrix is capable of deducing hybrid singularities, which cannot be identified by using the ...

Maximal Singularity-Free Orientation Subregions Associated with Initial Parallel Manipulator Configuration

open access: yesRobotics, 2018
Reduced workspace is the main parallel robot disadvantage. It is generally due to the robot configuration, mainly the platform orientation constraint, the present work intends to find the maximum sphere within the orientation workspace, i.e., the ...

Space-Constrained Scheduling Optimization Method for Minimizing the Effects of Stacking of Trades

open access: yesApplied Sciences, 2021
Existing SCS (space-constrained scheduling) studies fall short of minimizing the effect of the stacking of trades that decline productivity due to an increase in resources within a physically limited work area.
