Although several studies have described dual-tasking ability in normal aging, Mild Cognitive Impairment and Alzheimer's disease, no normative data for dual-task performance exist. Dual-tasking ability of 436 healthy individuals, aged 16-88 years, was assessed using a new paper-and-pencil dual-task paradigm. In this study, no age effect was detected, providing strong evidence that age does not a...

Several studies have found dual tasking to be impaired in Alzheimer's disease (AD), but unaffected by healthy ageing. It is not known if this deficit is specific to AD, or also present in other neurodegenerative disorders that can occur in later life, such as Parkinson's disease (PD). Therefore, this study investigated dual tasking in 13 people with PD, 26 AD and 42 healthy age-matched controls...

BACKGROUND Gait and cognitive functions can deteriorate during dual tasking, especially in people with neurological deficits. Most studies examining the simultaneous effects of dual tasking on motor and cognitive aspects were not performed in ecological environments. Using virtual reality technology, functional environments can be simulated to study dual tasking. OBJECTIVES The aims of this s...

Preemptive multi-tasking is a commonly used architecture for designing and implementing embedded real-time software. However, preemptive multi-tasking comes with its own costs. These costs include overheads due to preemptions and context-switches that result in waste of CPU bandwidth. Also, each task incurs a memory cost largely due to the need to maintain a separate stack for each task. These ...

Ada tasking is a powerful abstraction mechanism for developing concurrent embedded systems. However, many implementations of concurrent tasking have been seen as potentially unsafe for critical systems because of their high degree of indeterminism. The Ravenscar profile is a subset of Ada 95 tasking with purpose of providing a basis for the implementation of certifiable critical systems. ORK is...

In daily life elderly adults exhibit deficits when dual-tasking is involved. So far these deficits have been verified on a behavioral level in dual-tasking. Yet, the neuronal architecture of these deficits in aging still remains to be explored especially when late-middle aged individuals around 60 years of age are concerned. Neuroimaging studies in young participants concerning dual-tasking wer...

Multi-tasking optimization can usually achieve better performance than traditional single-tasking through knowledge transfer between tasks. However, current multi-tasking algorithms have some deficiencies. For high similarity problems, the that accelerate convergence rate of tasks has not been fully taken advantages of. low probability generating negative is high, which may result in degradatio...

Tasking deadlock is one of the most serious and complex problems concerning the reliability of concurrent systems with Ada. In this paper, tasking deadlocks which may occur in Ada 95 programs are investigated, a representation, named the Task-Wait-For Graph, for task synchronization waiting state of an Ada 95 program is proposed, and a runtime detection method for the tasking deadlocks based on...

Recent studies have shown that networks of memcapacitive devices provide an ideal computing platform low power consumption for reservoir systems. Random, crossbar, or small-world power-law (SWPL) structures are common topologies substrates to compute single tasks. However, neurological the interconnections cortical brain regions associated with different functions form a rich-club structure. Th...
