A test was conducted of the hypothesis that the training value of augmented feedback in a tracking situation will depend upon the discernibility of input and fundamental feedback signals. Subjects performed a one-dimensional compensatory tracking task using a knob for positional control over the cursor. For two of four groups of subjects the reference element was noisy, oscillating at random ab...

[1] The increase in atmospheric concentrations of water vapor with global warming is a large positive feedback in the climate system. Thus, even relatively small errors in its magnitude can lead to large uncertainties in predicting climate response to anthropogenic forcing. This study incorporates observed variability of water vapor over 2002–2009 from the Atmospheric Infrared Sounder instrumen...

This paper describes a new mechanism that might help with defining pattern sequences, by the fact that it can produce an upper bound on the ensemble value that can persistently oscillate with the actual values produced from each pattern. With every firing event, a node also receives an on/off feedback switch. If the node fires, then it sends a feedback result depending on the input signal stren...

this study is an attempt tofind the effect of four types of feedback(direct,underline,code,translation)on the writing performance of iranian learners ofjapanese as a foreign language.in this research,we have tried to suggest new ways of correcting students’writing through giving different kinds of feedback in the process of learning to write.the study focused on the accuracy of using prepositio...

Abstract—In multicast applications requiring receiver feedback, the primary impediment to receiver-set scalability stems from the feedback implosion problem. Some applications only need feedback from a single, representative receiver. For example, an adaptive video server may only need to know the video quality for the worst receiver. Soliciting a response from a receiver with the specific metr...

Recently, cloud computing is emerging drastically due to its ability to provide computing and other services to customers seamlessly. However, in heterogeneous environment, when there are various consumers and multiple service providers interacting and sharing resources, concern on security issues is crucial. Hence, the trust elements can be a motivating factor that can help to materialize the ...

Electromechanical nose-wheel steering systems give the Medium-haul air-crafts the needed maneuverability and durability. These air-crafts are of intermediate size. They must be able to utilize small airfields, having little or no service and maintenance facilities. During take-off, the nose-wheel steering keeps proper heading. Feedback from the nose-wheel heading is compared with the pilot comm...

We consider the feedback vertex set and feedback arc set problems in bipartite tournaments. We improve on recent results by giving a 2-approximation algorithm for the feedback vertex set problem. We show that this result is the best we can attain when using a certain linear program as the lower bound on the optimal value. For the feedback arc set problem in bipartite tournaments, we show that a...

Feedback is an important value in agile methodologies. It is also essential for any context where people are learning. Typically the focus is on giving learners feedback on their learning progress, either from an educator’s point of view or between the learners via peer feedback. This paper focuses on gaining feedback from learners. We discuss methods and good practices for encouraging learners...

this research explores the effects of three computer-mediated feedback modalities, that is, elicitation, recast, and meta-linguistics, on the learning of english participial, gerund, and infinitival phrases among iranian intermediate-level efl learners. the overriding focus of the present study was to investigate whether different types of feedback given through form-focused computer-human exch...
