Intelligent tutoring systems research aims to produce systems that meet or exceed the effectiveness of one on one expert human tutoring. Theory and empirical study suggest that affective states of the learner must be addressed to achieve this goal. While many affective measures can be utilized, posture offers the advantages of non intrusiveness and ease of interpretation. This paper presents an...

This paper proposes a novel method of estimating 3-D hand posture from images observed in complex backgrounds. Conventional methods often cause mistakes by mis-matches of local image features. Our method considers possibility of the mis-match between each posture model appearance and the other model appearances in a Baysian stochastic estimation form by introducing a novel likelihood concept “M...

Subjective rating is one of the alternatives to quantify hand force exertion. The rating of the Borg CR-10 scale has been used to quantify the perception of physical exertion. An experiment was conducted to test the grip force of male subjects at subjective ratings on the CR-10 scale under hand-posture conditions. It was found that the subjects applied a higher grip force than they perceived at...

The paper presents a cognitive architecture for posture learning of an anthropomorphic robotic hand. Our approach is aimed to allow the robotic system to perform complex perceptual operations, to interact with an human user and to integrate the perceptions by a cognitive representation of the scene and the observed actions. The anthropomorphic robotic hand imitates the gestures acquired by the ...

background: recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (gnrha) at beginning of ovarian stimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (ivf) cycles. objective:the efficacy of gnrha stop protocol in poor responder patients in ivf cycles was assessed...

We attempt to explain why standard explanations of the poverty of nations are unsatisfactory. We first argue that human capital is low in poor countries because its production has increasing returns with respect to life expectancy. We then show that the reason why capital does not flow to poor countries (the Lucas paradox) can readily be explained once market prices rather than PPP prices are u...

airway mucus hypersecretion health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. the aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

the microdose gnrh agonist (gnrh-a) flare protocol may have a particular value for previously poor responders in whom it has been observed to stimulate dramatic increases in serum fsh. the purpose of this study was to determine the effects of microdose gnrh-a in poor responders. this is a clinical trial with before and after design. this study was done in research and clinical center for infert...

This paper addresses the issue in scenario-based understanding of human behavior from videos in a nursing care monitoring system. The analysis is carried out based on experiments consisting of single-state scenarios and multi-state scenarios where the former monitors activities under contextual contexts for elementary behavior reasoning, while the latter dictating the elementary behavior order ...
