AIMS To examine the relation between measures of vision and ability to perform daily living tasks in those visually impaired with macular degeneration. METHODS A visual functioning index (daily living tasks dependent on vision: DLTV) was used to evaluate patients' perception of their ability to perform vision dependent tasks. Distance visual acuity, near visual acuity, reading speed, and cont...
The objective of this study was to investigate potential associations between an individual's psychophysical maximum acceptable force (MAF) during pushing tasks and biomechanical tissue loads within the lumbar spine. Ten subjects (eight males, two females) pushed a cart with an unknown weight at one push every two minute for a distance of 3.9 m. Two independent variables were investigated, cart...
We developed a computational model of the mushroom body (MB), a prominent region of multimodal integration in the insect brain, and tested the model’s performance for non-elemental associative learning in visual pattern avoidance tasks. We employ a realistic spiking neuron model and spike time dependent plasticity, and learning performance is investigated in closed-loop conditions. We show that...
In this paper, we analyze the operational flow of two hardware implementations of the Task Superscalar architecture. The Task Superscalar is an experimental task based dataflow scheduler that dynamically detects inter-task data dependencies, identifies task-level parallelism, and executes tasks in the out-of-order manner. In this paper, we present a base implementation of the Task Superscalar a...
Lateral prefrontal and posterior parietal cortical areas exhibit task-dependent activation during working memory tasks in humans and monkeys. Neurons in these regions become synchronized during attention-demanding tasks, but the contribution of these interactions to working memory is largely unknown. Using simultaneous recordings of neural activity from multiple areas in both regions, we find w...
Recent versions of international high-stakes tests like TOEFL and IELTS have made use of integrated tasks in addition to the traditional independent tasks in a claim to provide a more realistic estimation of the test takers’ language abilities. The present study aimed to investigate how test takers’ performance may differ on such tasks. As such, the test takers’ performance was compared on IELT...
With the up rise of fourth paradigm, that is discovery of science over a prolonged period of time, scientific workflows commence to amend their status amongst innumerous science subject areas including physics, astronomy, biology, chemistry, earthquake science and many more. In Scientific workflows, a heavy volume of data processing is required and workflows with up to a few million tasks are n...
In the interest of achieving higher reliability, mobile ad hoc grid should apply a fault tolerance in resource allocation scheme. Resource allocation plays a critical role in mobile ad hoc grids due to the dynamic nature of nodes connection. Allocating appropriate resources for the tasks can avoid uncompleted tasks and ensure service reliability. We propose two approaches for avoiding tasks fai...
In this paper we propose a greedy heuristic to solve the non preemptive multiprocessor static scheduling problem with precedence and strict periodicity constraints. The system of periodic tasks is described by a graph where dependent tasks are connected by precedence constraints. First, each task is repeated within the LCM of all periods of tasks (hyper-period) allowing to unroll the graph over...
