Working memory is an executive function, which involves holding information in mind and mentally working with it (Diamond, 2013). A widely used measure for the assessment of working memory function is the n-back task (Owen et al., 2005). Here, participants are typically instructed to monitor a series of stimuli and to respond whenever a stimulus is presented that is the same as the one presente...

Blur detection is affected by retinal eccentricity, but is it also affected by attentional resources? Research showing effects of selective attention on acuity and contrast sensitivity suggests that allocating attention should increase blur detection. However, research showing that blur affects selection of saccade targets suggests that blur detection may be pre-attentive. To investigate this q...

For many classiication tasks, the set of available task instances can be roughly divided into regular instances and exceptions. We investigate three learning algorithms that apply a diierent method of learning with respect to regularities and exceptions, viz. (i) back-propagation, (ii) cascade back-propagation (a constructive version of back-propagation), and (iii) information-gain tree (an ind...

This paper aims to address the solution for the Subtask 1 of Shared Task on transliterated search,a task in FIRE ’14. The task addresses the problem of data containing English words and transliterated words of Indian languages in English.The task calls for language identification and subsequent back transliteration into the native Indian scripts.The system proposed herewith implements Language ...

This study was conducted to investigate the effect of the exposure to dim light during sleep on the brain activation while conducting tasks requiring working memory. 23 young healthy subjects participated in this study. The subjects were instructed to sleep in a polysomnography room with no light exposure on the first night and under a dim light condition of 5 lux or 10 lux on the second night....

Push back design as a complex task, is one of the major steps in the open pit mines planning. Push backs can be generated by varying economic factors such as commodity price, mining cost, processing cost, etc. Another important issue in generating push backs is grade uncertainty, which can cause the problem be more complex. Conventional methods of push back design ignore grade uncertainty. To o...

introduction: work pressure and excessive workload can jeopardize and impair the people’s health. one of these impairments is musculoskeletal disorders. among these disorders, low back pain is the most common and most costly problem. the purpose of this study was to investigate the relationship between workload and prevalence of low back pain in assembly line workers of a car manufacturing fact...

Background. Sleep is assumed to be a critical factor for human physiological and cognitive function. Lack of sleep is a common condition in daily life. Objectives. The purpose of this study was to evaluate the effects of 24-hour sleep deprivation on cognitive and motor skills in university students. Methods. The participants were volunteers that consisted of 290 male students aged 19-25 years...

The auditory steady-state response (ASSR) is an oscillatory brain activity evoked by repetitive auditory stimuli. Previous studies have reported that the power and phase locking index (PLI) of ASSR could be modulated by the degree of workload. However, those studies used different physical stimuli for tasks of differing difficulty, and the effect of the internal workload itself has not been cle...
