Universities strive to collect feedback from students to improve their courses and tutorship. Such feedback is often collected at the end of a course via survey forms. However, such methods in collecting feedback are too controlled, slow, and passive. With the rise of social media, many students are finding online venues to group and share their experiences and seek peers’ support. OUSocial2 is...

This paper studies the problem of information revelation in a multi-stage tournament where the agents’ effort in each stage gives rise to a stochastic performance signal privately observed by the principal. The principal controls the agents’ effort incentive through the use of a feedback policy, which transforms his private information into a public announcement. The optimal feedback policy is ...

This paper  presents a nonlinear controller for a Distribution Static Compensator (DSTATCOM) of a microgrid incorporating the Distributed Generation (DG) units. The nonlinear control has been designed based on partial feedback linearization theory and Proportional-Integral-Derivative (PID) controllers try to adjust the voltage and trace the output. This paper has proposed a combination of a fuz...

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...

The current profile along the 126 ns, multi-bunch beam pulse in the Next Linear Collider Test Accelerator (NLCTA) is monitored with fast toroids (rise time ~1 ns). Inserted at several positions along the beam line, they allow us to track current transmission as a function of position along the bunch train. Various measurements, such as rise time, current, width, and slope, are made on the digit...

*Thanks are due to Hans Rott and Maurice Pagnucco who have commented on the July draft of this essay and who subsequently sent me a draft of their ideas on contraction. I have sought here to explain how I came to change my mind and favor mild contractions (or severe withdrawals as Rott and Pagnucco call such contractions) and to indicate some of the relations between the approach of Rott and Pa...

In this paper, we propose a novel distance-based camera network topology inference method for efficient person re-identification. To this end, we first calibrate each camera and estimate relative scales between cameras. Using the calibration results of multiple cameras, we calculate the speed of each person and infer the distance between cameras to generate distance-based camera network topolog...

Kocevski et al. (2003) found that there is a linear relation between the rise time and the width of gamma-ray burst pulses detected by the BATSE instrument based on their empirical functions. Motivated by this, we investigate the relationship based on Qin et al. (2004) model. Theoretical analysis shows that each of the two quantities, the rise time and the width of observed pulse, is proportion...
