We report on our extended research on GymSkill, a smartphone system for comprehensive physical exercising support, from sensor data logging, activity recognition to on-top skill assessment, using the phone’s built-in sensors. In two iterations, we used principal component breakdown analysis (PCBA) and criteria-based scores for individualized and personalized automated feedback on the phone, wit...

A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively...

the aim of this study was to determine the interactional effects of various video shows (skilled and self-model) and feedback type on performance and learning of dart throwing skill. 90 volunteers were randomly divided into 6 groups including self-control, experimenter control and yoked feedback that received either skilled model or self-model. three groups who watched the skilled model observe...

OBJECTIVE Feedback is a technique used in medical education to help develop and improve clinical skills. A comprehensive review article specifically intended for the emergency medicine (EM) educator is lacking, and it is the intent of this article to provide the reader with an in-depth, up-to-date, and evidence-based review of feedback in the context of the EM clerkship. METHODS The review ar...

 The purpose of this study is to investigate the effects of asynchronous computer-mediated versus conventional corrective feedback on learners' writing accuracy. Three groups of learners took part in the study: asynchronous feedback group, conventional feedback group, and a control group. Asynchronous feedback group students received explicit feedback on the targeted structure via e-mail, while...

The following paper is an account of a commercially successful and viable expert system entitled FRED (Feedback Reporter Evaluating Development). Expert systems offer a consistent approach to providing feedback to individuals that people with personal biases and emotions may find difficult to achieve. The text used in the expert system is sensitive and carefully worded by a team of skilled prof...

We investigate the effect of imperfect feedback on the ǫ-outage capacity of incremental relaying in the low signal-to-noise ratio (SNR) regime. We show that imperfect feedback leads to a rescaling of the pre-log factor (comparable to the multiplexing gain for networks operating in the high SNR regime) and thus reduces the ǫ-outage capacity considerably. Moreover, we investigate the effect of di...

In Multi-user Feedback support system or 360 0 Feedback, data on the performance of an individual are collected systematically from a number of stakeholders and are used for improving performance. The 360 0 Feedback approach provides a consistent management philosophy meeting the criterion outlined previously. The 360 0 feedback based appraisal is a comprehensive method where in the feedback ab...

A versatile optical trap has been constructed to control the position of trapped objects and ultimately to apply specified forces using feedback control. While the design, development, and use of optical traps has been extensive and feedback control has played a critical role in pushing the state of the art, few comprehensive examinations of feedback control of optical traps have been undertake...
