This study explored corrective feedback (CF) types and their relationship to L2 learners’ intelligence types. Participants were 60 intermediate L2 learners aged 18-29 in Isfahan, Iran. Based on their intelligence types as intrapersonal and interpersonal, the participants were divided into 2 groups. McKenzie’s MI Inventory (1999) and a researcher-designed questionnaire on CF types were employed....

This document contains a description of experiments for the 2008 Relevance Feedback track. We experiment with different amounts of feedback, including negative relevance feedback. Feedback is implemented using massive weighted query expansion. Parsimonious query expansion using Dirichlet smoothing performs best on this relevance feedback track dataset. Additional blind feedback gives better res...

This document contains a description of experiments for the 2008 Relevance Feedback track. We experiment with different amounts of feedback, including negative relevance feedback. Feedback is implemented using massive weighted query expansion. Parsimonious query expansion using only relevant documents and Jelinek-Mercer smoothing performs best on this relevance feedback track dataset. Additiona...

We are motivated by the fact that fixed Increase rates and Decrease ratios for AIMD cannot adjust TCP’s performance to the Internet’s diverse networking conditions. Indeed, we find that fixed values for the increase/decrease factors of AIMD restrain flexibility, which is a fundamental property of transport protocols in order to guarantee utilization and fairness in Modern and Future internetwor...

The controversy over multiple category-learning systems is reminiscent of the controversy over multiple memory systems. Researchers continue to seek paradigms to sharply dissociate explicit category-learning processes (featuring category rules that can be verbalized) from implicit category-learning processes (featuring learned stimulus-response associations that lie outside declarative cognitio...

The concept of social search has been acquiring importance in the WWW as large-scale collaborative computing environments have become feasible.This field focuses on the reader’s perspective in order to assign relevance and trustworthiness to web pages. Although current web searching technologies tend to rely on explicit human recommendations, these techniques are hard to scale as feedback is ha...

A given explicit piecewise affine representation of an MPC feedback law is approximated by a single polynomial, computed using linear programming. This polynomial state feedback control law guarantees closed-loop stability and constraint satisfaction. The polynomial feedback can be implemented in real time even on very simple devices with severe limitations on memory storage.

Solutions to constrained linear model predictive control (MPC) problems can be pre-computed off-line in an explicit form as a piecewise linear (PWL) state feedback defined on a polyhedral partition of the state space. This admits implementation at high sampling frequencies in real-time systems with high reliability and low software complexity. Recently, algorithms that determine an approximate ...

We consider the problem of stabilization of a one-dimensional wave equation that contains instability at its free end and control on the opposite end. In contrast to classical collocated “boundary damper” feedbacks for the neutrally stable wave equations with one end satisfying a homogeneous boundary condition, the controllers and the associated observers designed in the paper are more complex ...
