control of robotic systems is an interesting subject due to their wide spectrum applications in medicine, aerospace and other industries. this paper proposes a novel continuous control mechanism for tracking problem of a 5-dof upper-limb exoskeleton robot. the proposed method is a combination of a recently developed robust integral of the sign of the error (rise) feedback and neural network (nn...

This research examines two different kinds of feedback-mechanism to scaffold problem solving as well as interaction in computer-mediated seminars. An automated feedback mechanism has been used to enhance interaction and group wellbeing during computer supported collaborative learning. We tracked individual contribution behaviour as well as learners’ motivation during collaborative problemsolvin...

abstract the study aimed at investigating the efficacy of written corrective feedback (cf) in improving iranian efl learners’ grammatical accuracy. it compared the effects of focused and unfocused written cf on the learners’ grammatical accuracy. 75 efl students formed a one control and two experimental groups. the focused feedback group was provided with error correction in tenses. the unfocus...

Reliable multicast applications use feedback messages to report receiving status of receivers. This results in the well-known feedback implosion and scalability problems. Also, quick loss response from receivers and low multicast overhead, e.g. control messages and session messages, are desired. We present a feedback implosion control mechanism that groups the multicast members into areas, with...

OBJECTIVE To develop and validate a mechanism for patients to provide feedback on safety experiences following a care transfer between organisations. DESIGN Qualitative study using participatory methods (codesign workshops) and cognitive interviews. Workshop data were analysed concurrently with participants, and cognitive interviews were thematically analysed using a deductive approach based ...

It has been found recently that feedback in an ATM network is useful in the long run to alleviate congestion. This general conclusion, although theoretically important, does not address the practical concern aa to how the network behaves when it is adjusting itself in short to medium range. The work reported in this paper is motivated by this practical concern. A new feedback based dynamic traf...

Innovation is the means and sustainability is objective (or idea). Innovation services on sustainability and sustainability guides innovation. Both are cause-and-effect, form the positive feedback mechanism, and form a virtuous cycle, thus make both mutual promotion and common development and evolution. The key is the positive feedback mechanism formed between innovation and sustainability. Bas...

In this manuscript, we evaluate the application of the singular value decomposition (SVD) to a search term suggestion system in a pay-for-performance search market. We propose a novel positive and negative relevance feedback method for search refinement based on orthogonal subspace projections. We apply these methods to the subset of Overture’s market data and demonstrate the effect of SVD and ...

Standard models of the visual object recognition pathway hold that a largely feedforward process from the retina through inferotemporal cortex leads to object identification. A subsequent feedback process originating in frontoparietal areas through reciprocal connections to striate cortex provides attentional support to salient or behaviorally-relevant features. Here, we review mounting evidenc...

Closing the structure-function divide is more challenging in the brain than in any other organ (Lichtman and Denk, 2011). For example, in early visual cortex, feedback projections to V1 can be quantified (e.g., Budd, 1998) but the understanding of feedback function is comparatively rudimentary (Muckli and Petro, 2013). Focusing on the function of feedback, we discuss how textbook descriptions m...
