This thesis proposed a framework for conceptualizing critical thinking in language learning. A learning environment where collaborative learning and network technology were combined − computer-mediated collaborative learning (CMCL) − was set up. The main aim was to study the potential of the learning environment in promoting critical thinking (CT) in language learning. The proposed framework of...

Accurate iris segmentation is presented in this paper, which is composed of two parts, reflection detection and eyelash detection. Eyelashes are classified into two categories, separable and multiple. An edge detector is applied to detect separable eyelashes and intensity variances are used to recognize multiple eyelashes. Reflection is also divided into two types, strong and weak. A threshold ...

With todays wide acceptance of distributed computing, a rapidly growing number of application domains are emerging, leading to a growing number of ad-hoc solutions, rigid and poorly interoperable. Our response to this challenge is a platform for building flexible and interoperable execution environments (including language and system aspects) called the Virtual Virtual Machine. This paper prese...

We use the structural similarity of certain Coxeter Artin Systems to the Yang–Baxter and Reflection Equations to convert representations of these systems into new solutions of the Reflection Equation. We construct certain Bethe ansatz states for these solutions, using a parameterisation suggested by abstract representation theory.

Reflection and collaborative reflection are common activities at workplace, in which people alone or together with colleagues revisit experiences to learn for future situations. Often support needs arise during reflection and for example people get stuck and don’t know how to continue. We propose to fill this gap with prompting as tool-supported scaffolding mechanism. Based on literature and ou...

The paper analyzes territorial modernization and the importance of the urban phenomenon for recent changes in the Amazon Region. Using the notions of “forest towns” and “towns in the forest”, this paper intends to understand diffuse urbanization, which is in progress, in a regional context. With this focus, it considers examples of urban forms and attributes regarding provisions for external ec...

Impedance metasurface is composed of electrical small scatters in two dimensional plane, of which the surface impedance can be designed to produce desired reflection phase. Tunable reflection phase can be achieved by incorporating active element into the scatters, but the tuning range of the reflection phase is limited. In this paper, an active impedance metasurface with full 360° reflection ph...

there is a bilateral relationship between psychoanalysis and literature. literature enlivens the soul and psychoanalysis dissects literature. what psychoanalysts express today has attended in the past literature and is proposed now scientifically after psychoanalysis was identified as a science. by analyzing an art work from the perspective of psychology, it seems being possible to understand a...
