In this paper, a Virtual Learning Environment (VLE) is used to overcome difficulties identified from the student and professors perspective when participating in an Object Oriented Programming (OOP) class. A Blended Learning strategy is used for the students to self-evaluate their concepts and skills gained in class, and from there, perform on-line activities to improve or solve theoretical or ...

This article describes the strategy we adopted to evaluate the implementation of virtual learning environment (VLE) across the institution. The paper presents the theoretical model we developrf and the methods used. The availability of a VLE has affected many aspects of University life and practices and we are endeavouring to understand the impact of the changes on staff and students in terms o...

types of teamwork, and by allowing learning to be a continuous, time-independent process utilizing electronic media and electronic resources. In addition, as the Internet and especially the World Wide Web (WWW) also promise to revolutionize the dynamics of commerce, the VLE is intended to provide business students with an opportunity to develop a cursory understanding of the e-commerce dynamics...

Removal of sulfur from gasoline is one of the major processes in refineries. Designing of removal process requires phase equilibrium data of the sulfur with various hydrocarbon systems. 3-Methylthiphene is an organic sulfur compound found in gasoline. In the present work VLE data of 3-Methylthiophene with various hydrocarbons were modeled using genetic algorithm. VLE data were modeled using Wil...

Virtual Learning Environments (VLEs) are an expression of the post-modern school. In this paper we discover how the functional requirements of the VLEs affect and are being affected by the educational, ethnographic and social spaces. It is supported that educational effectiveness of VLE is not proportional only to the quality of learning material, but also to the general educational context of ...

Using 3D virtual environments for educational purposes is becoming attractive because of their rich presentation and interaction capabilities. Furthermore, dynamically adapting the 3D virtual environment to the personal preferences, prior knowledge, skills and competence, learning goals, and the personal or (social) context in which the learning takes place becomes interesting, as there is a bu...

In process simulation, reliable and accurate property estimation methods play an important role in the solution of various simulation problems where convergence is often traced to failures in the reliable predictions of physical and thermodynamic properties. Convergence and reliability of the simulation is heavily dependent on the fluid package selected. Predictions of phase equilibrium using v...

Isothermal vapour−liquid equilibrium (VLE) for four binary systems involving R1234yf (R1234yf + R134a, R152a, R1233zd(E) and R1233xf) were measured at temperatures from 278.15 to 348.15 K. The experiments conducted by means of a “static−analytic” apparatus with phase analysis via gas chromatography, resulting uncertainties 0.6 K temperature, 8 kPa pressure maximum 0.007 vapour liquid mole fract...

This paper discusses the role of institutional issues in the deployment of infrastructures for learning and the ways in which they can impact on the range of choices and opportunities for collaboration in university education. The paper is based on interviews with 12 key informants selected from relevant staff categories during the deployment of a new institutional infrastructure in a large UK ...

Background and AimsVolumetric laser endomicroscopy (VLE) is an advanced imaging modality used to detect Barrett’s esophagus (BE) dysplasia. However, real-time interpretation of VLE scans complex time-consuming. Computer-aided detection (CAD) may help in the process image interpretation. Our aim was train validate a CAD algorithm for VLE-based BE neoplasia.MethodsThe multicenter, PREDICT study, ...
