Traditionally, scholars in physics education research have focused on students solving well-structured learning activities at the university. However, due to their constrained nature, these problems hinder collaboration and idea generation. In order encourage student decision making demands among undergraduate an introductory course, we utilized a real-world problem where groups were asked comp...

Structured syntactic knowledge is important for phrase reordering. This paper proposes using convolution tree kernel over source parse tree to model structured syntactic knowledge for BTG-based phrase reordering in the context of statistical machine translation. Our study reveals that the structured syntactic features over the source phrases are very effective for BTG constraint-based phrase re...

We propose a novel model for meta-generalisation, that is, performing prediction on novel tasks based on information from multiple different but related tasks. The model is based on two coupled Gaussian processes with structured covariance function; one model performs predictions by learning a constrained covariance function encapsulating the relations between the various training tasks, while ...

This paper is concerned with the problem of design and implementation a robust adaptive control strategy for flexible joint electrically driven robots (FJEDR), while considering to the constraints on the actuator voltage input. The control design procedure is based on function approximation technique, to avoid saturation besides being robust against both structured and unstructured uncertaintie...

An increasingly important class of keyword search tasks are those where users are looking for a specific piece of information buried within a few documents in a large collection. Examples include searching for someone’s phone number, the schedule for a meeting, or a package tracking URL, within a personal email collection. We refer to such tasks as “precision-oriented search tasks”. While moder...

Today, learners’ interaction and collaborative task performance have attracted increasing attention from language teachers and researchers. The present study investigated whether collaborative pre-planning, task complexity manipulation, and language proficiency level play a role in learners’ interactions. To this end, 128 EFL learners from two different language proficiency levels carried out t...
