The main goal in task planning is to build a sequence of actions that takes an agent from initial state state. In robotics, this particularly difficult because usually have several possible results, and sensors are prone produce measurements with error. Partially observable Markov decision processes (POMDPs) commonly employed, thanks their capacity model the uncertainty modify monitor system. H...

the aim of this investigation was to compare the level and the pattern of attention demands of a volleyball jumping serve using a probe reaction time (rt) technique. 14 junior elite volleyball players performed 60 jumping serves (js) with their preferred hand. jumping serve was performance as the primary task and verbal rt that was administered in four probe positions (pp) as secondary task. re...

INTRODUCTION Sleep deprivation has detrimental effects on cognitive processes, including decision making. The present study investigated how 72 h of sleep deprivation influenced individual neural performance in the Iowa gambling task using event-related potential technology. METHODS Eleven healthy male adults who participated in our study were randomized to be either in group with 72 h of soc...

Objectives: The aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). Methods: This cross-sectional study was conducted by participating 20 young people (22.75±2.29). Each subject performed one-leg standing as balance task for e...

Prior research examined how controllers plan in their traditional environment and identified various information uncertainties as detriments to planning. A planning aid was designed to reduce this uncertainty by perceptually representing important constraints. This included integrating spatial information on the radar screen with discrete information (planned sequences of air traffic). Previous...

This paper provides an approach to integrating geometric motion planning with logical task planning for long-horizon tasks in domains with many objects. We propose a tight integration between the logical and geometric aspects of planning. We use a logical representation which includes entities that refer to poses, grasps, paths and regions, without the need for a priori discretization. Given th...

BACKGROUND Pervasive negative thoughts about the self are central to the experience of depression. Brain imaging studies in the general population have localised self-related cognitive processing to areas of the medial pre-frontal cortex. AIMS To use fMRI to compare the neural correlates of self-referential processing in depressed and non-depressed participants. METHOD Cross-sectional compa...
