Fifty 8-year-old children, 25 classified as normal and 25 as learning disabled, participated in a study to determine whether they could be differentiated into their respective groups by using four tasks from the Devereux Test of Extremity Coordination: opposition, foot patting, finger wiggling, and heel-toe walking with the eyes closed. Each chilld received numerical scores based on the number ...

For a class of robot arms, a proportional derivative (PD) controller plus gravity compensation yields the global asymptotic stability for regulation tasks, and some proportional-integral-derivative (PID) controllers guarantee local regulation without gravity cancellation. However, these controllers cannot render asymptotic stability for tracking tasks. In this paper, a simple decentralized cont...

The fork-join queue models parallel resources where arriving jobs divide into various number of sub-tasks that are assigned to unique devices within the parallel resource. Each device in the parallel resource is modeled by M=M=1 queueing servers. A job completes execution and departs the parallel resource after all its sub-tasks complete execution. This paper analyzes N-server fork-join queues ...

Individuals employed in forensic or security settings are often required to compare faces of ID holders to document photographs, or to recognise the faces of suspects in closed-circuit television footage. It has long been established that both tasks produce a high error rate amongst typical perceivers. This study sought to determine the performance of individuals with exceptionally good face me...

In this paper we attempt to analyze the problem of centrally allocating tasks to selfinterested agents in environments characterized by high uncertainty. The analysis is based on equilibrium dynamics, taking into account the agents’ short-term and long-term considerations. The model reflects a rich realism by allowing both tasks and agents to dynamically arrive in the environment. This is corre...

abstract the present study examined the effect of genre-based tasks on efl learners' speaking performance and probed whether genre-based tasks may empower efl learners to perform better on speaking tests. a further concern of the study was to explore whether the effect of genre-based tasks on speaking ability of efl learners varied across different age groups, i.e. teenagers (13-16 years o...

the present study adopts the perspective that metacognitive strategy instruction is bound to occur inside the classroom especially on oral tasks. accordingly, the researchers investigated whether metacognitive strategy instruction prior to oral tasks was more successful than conventional ways in improving efl learners’ oral proficiency. to this end, 56 participants studying in a language school...

Transportation of large objects or their manipulation in hazardous environments are tasks where the utilization of groups of mobile robots working in a cooperative fashion can be of great advantage. To execute such tasks, a multirobot formation control framework is necessary in order to coordinate the motions of the robots in the group. In this article, a particular formation control approach c...

Head injury accounts for a quarter of trauma related deaths but for a much larger proportion of lifelong disability. With the rise in high speed traffic, the number of high velocity injuries, resulting in mainly diffuse head trauma has also increased drastically. The cognitive and behavioral sequelae of closed head injury may be extensive and diverse -ranging from cognitive deficits to psychiat...
