Performance analysis of task migration in a portable parallel environment
Proceedings of the 1996 ICPP Workshop on Challenges for Parallel Processing, 2002The performance of a preemptive task migration algorithm implemented in a portable parallel programming environment is reported. The experiments were conducted using the ELMO system which extends languages like C with migratable parallel tasks. Preemptive task migration support has been provided for checkpointing of tasks during debugging and replay in

A Performance Analysis on Task Allocation Using Social Context
2012 Second International Conference on Cloud and Green Computing, 2012Task allocation strategy has a great impact on the performance of the workflow management system in workflow scheduling. Most task allocation algorithms focus on the resource status only. Few algorithms consider the change of efficiency while performer working with different people.

A Theoretical Analysis of the Impact of Task Scope on Employee Performance
Academy of Management Review, 1976A model is presented linking task scope to employee motivation and performance. Emphasis is given to the importance of objective, environmental (versus psychological) conceptualizations of task scope. Psychological reactions to variations in task scope are depicted as dependent on intervening constructs.

A Detailed Analysis of Task Performance With and Without Computer Monitoring
International Journal of Human-Computer Interaction, 2003Participants (N = 115) performed a computerized task under 3 conditions: no supervision, direct human supervision, and computer monitoring. Differences in performance across groups was evaluated using summary performance measures and detailed analyses of group performance over time.

Analysis of hand movements during the performance of positioning tasks
Ergonomics, 1983An electroacoustic method was developed to analyse hand movements in space. This method was used to analyse the control error of the hand-arm system during the performance of a simple cyclic positioning task. It could be shown that the traces of the hand movements become significantly more dispersed with increasing time at work.

Spatial Task Performance: A Meta-Analysis
Journal of Visual Impairment & Blindness, 1988The literature which compared spatial task performance of blind and sighted subjects was analyzed using a meta-analytic approach. Effect sizes were computed for comparisons between early versus late onset visually impaired subjects, early onset versus sighted, late onset versus sighted, and mixed onset versus sighted.

Motor expertise and performance in spatial tasks: A meta-analysis
Human Movement Science, 2017The present study aimed to provide a summary of findings relevant to the influence of motor expertise on performance in spatial tasks and to examine potential moderators of this effect. Studies of relevance were those in which individuals involved in activities presumed to require motor expertise were compared to non-experts in such activities. A final

A computerized analysis of robotic versus laparoscopic task performance
Surgical Endoscopy, 2007Robotic technology has been postulated to improve performance in advanced surgical skills. We utilized a novel computerized assessment system to objectively describe the technical enhancement in task performance comparing robotic and laparoscopic instrumentation.Advanced laparoscopic surgeons (2-10 yrs experience) performed three unique task modules ...
