this paper introduces a technique for controlling a class of uncertain chaotic systems using an adaptive fuzzy proportional-integrator-derivative (pid) controller with h∞ tracking performance. the purpose of this work is to achieve optimal tracking performance of the controller using backtracking search algorithm (bsa). bsa, which is a novel heuristic algorithm, has an easy structure with singl...

Integrating wiki-based activities into education encourages development of students’ competencies that are important for their future professional life. As wikis support social learning and interaction, when working with them students learn to cooperate, plan and organize collaborative tasks, create concepts, express ideas, etc. Many teachers recognize undeniable benefits of a wiki in learning ...

The goal of this paper is to evaluate commonly held criticisms of the practice of ability tracking in high school mathematics. To do so, I employ data from the National Education Longitudinal Study of 1988 and follow-ups to model classroom selection and education production. This paper will focus only on the causes and effects of tracking on students who were tracked as low-ability in eighth gr...

For distance education utilizing shared Virtual or Augmented Reality (VR/AR) applications, reliable network distribution of educational content is of prime importance. In this paper we summarize the development of software components enabling stable and reliable distribution of an existing educational AR application for geometry education. Our efforts focus on three main areas: (1) For long dis...

This paper addresses learning analytics for learner awareness in remote laboratories. The objectives we identified to provide selfand social awareness while learners are practicing in their virtual learning environment are threefold: (1) the definition of a performance metric that requires no assessment tests, (2) the tracking of data to infer that metric in real time, (3) the visualization of ...

nowadays, scientific c findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. magnetic resonance ima...

Multiple target tracking (MTT) is taken into account as one of the most important topics in tracking targets with radars. In this paper, the MTT problem is used for estimating the position of multiple targets when a 2-D radar is employed to gather measurements. To do so, the Joint Probabilistic Data Association Filter (JPDAF) approach is applied to tracking the position of multiple targets. To ...

Education Policy and Equality of Opportunity We provide a measure of equality of educational opportunity in 54 countries, estimated as the effect of family background on student performance in two international TIMSS tests. We then show how organizational features of the education system affect equality of educational opportunity. Our model predicts that late tracking and a long pre-school cycl...

ePortfolios can both facilitate and assess knowledge transfer from lower division, general education courses to upper division, discipline-specific courses. The chapter opens with a discussion of Teaching/Writing in Thirdspaces (Grego & Thompson, 2008) and argues that the notion of thirdspace can apply to the distance between general education courses and the information skills required within ...
