Descending stairs demands attention and neuromuscular control, especially with dual-tasking. Studies have demonstrated that stroke often degrades a survivor's ability to descend stairs. Tai Chi has been shown to improve dual-tasking performance of healthy older adults, but no such study has been conducted in stroke survivors. This study investigated the effect of Tai Chi training on dual-taskin...

The sensor tasking problem in sensor networks involves the representation of users’ tasks (user-level tasking) in a form which a sensor network needs to perform required operations (sensor-level tasking) leading to satisfaction of the tasks. We analysed four approaches to task representation (TR) in sensor networks: the Open Geospatial Consortium’s Sensor Web Enablement, Goal Lattices, Semantic...

Walking in daily life places high demands on the interplay between cognitive and motor functions. A well-functioning dual-tasking ability is thus essential for walking safely. The aims were to study longitudinal changes in gait function during single- and dual-tasking over a period of two years among people with initially mild AD (n=21). Data were collected on three occasions, twelve months apa...

Background This study focussed on the effect of dual versus single tasking on balance, gait and cognition in veterans with mild traumatic brain injury (mTBI). We examined the correlation between these parameters, with responses to questions on community reintegration activities. Method 22 male and female veterans (aged 19-65) walked along a narrow and 6.1-meter long path, both at their self-s...

[Purpose] The purpose of the study was to investigate the postural control and cognitive performance of older adults when stepping backward with and without a concurrent cognitive task. [Subjects and Methods] Thirty young adults and twenty-eight older adults (mean age=21.3 ± 1.2 and 72.2 ± 5.7 years, respectively) were recruited. Participants were asked to step backward and then maintain a sing...

Multi-tasking, managed runtime environments (MREs) for modern type-safe, object-oriented programming languages enable isolated, concurrent execution of multiple applications within a single operating system process. Multi-tasking MREs can potentially extract high-performance on modern desktop and hand-held systems through aggressive sharing of classes and compiled code, and by exploiting high-l...

Remotely sensed images have become an important source of information for actors involved in disaster management and satellite-based emergency mapping (SEM) is increasingly used to support the response phase first hours days after a occurs. The delivery timeliness crisis key success SEM. In Copernicus Emergency Management Service (CEMS), procedure was tested during past 5 years which links Euro...

An Ada tasking kernel is implemented as a layer beneath the Linux operating system. This provides low overhead and precise control of execution timing for real-time Ada tasks, which execute within the Linux kernel address space, while allowing the Linux operating system to execute non-real-time tasks in the background. The Ada tasking kernel is derived from Yodaiken's Real-Time Linux kernel, wi...

Remote tasking encompasses different functionality, such as remote forking, multiple remote spawning, and task migration. In order to overcome the relatively high costs of these mechanisms, optimizations can be applied at various levels of the underlying operating system or application. Optimizations include concurrent message transmission, increased throughput and reduced latency at the distri...
