The Education through Virtual Experience (EVE) research group based at the National University of Ireland Maynooth have successfully developed an online Virtual Learning Environment (VLE) for Astronomy as part of the Virtual Telescopes in Education (VTIE) project. The VTIE VLE has been developed to provide online software support for the engagement of schoolchildren and their teachers in a scie...

This paper explores educational uses of virtual learning environment (VLE) concerned with issues of learning, training and entertainment. We analyze the state-of-art research of VLE based on virtual reality and augmented reality. Some examples for the purpose of education and simulation are described. These applications show that VLE can be means of enhancing, motivating and stimulating learner...

• 3-Component Margules equation was used to predict vapor–liquid equilibria. Infinite dilution activity coefficients are the sole input for solvent pre-selection. Industrial cases were validate approach. Molecular solvents, ILs and DESs incorporated in screening. We present an easily accessible, open-access approach fast pre-selection of solvents extractive distillation at isobaric isothermal c...

BACKGROUND We introduced a series of computer-supported workshops in our undergraduate statistics courses, in the hope that it would help students to gain a deeper understanding of statistical concepts. This raised questions about the appropriate design of the Virtual Learning Environment (VLE) in which such an approach had to be implemented. Therefore, we investigated two competing software de...

Under consideration are the general set of Human computer Interaction (HCI) and Educational principles from prominent authors in the field and the construction of a system for evaluating Virtual Learning Environments (VLEs) with respect to the application of these HCI and Educational Principles. A frequency analysis of principles is used to obtain the most significant set. Metrics are devised t...

In this work, a more accurate prediction of liquid evaporation flux has been achieved. The statistical rate theory approach, which is recently introduced by Ward and Fang and exact estimation of vapor pressure in the layer adjacent to the liquid–vapor interface have  been used for prediction of this flux. Firstly, the existence of an equilibrium layer adjacent to the liquid-vapor interface ...

This paper contr ibutes to the discussion on information and communicat ion technology ( ICT) for educat ional purposes. Research was done on the use a vir tual learning environment (VLE) based on Internet technology during a pract ical course for economic students at the Vri je Universi te i t Amsterdam. The VLE has been used f o r many dtferent purposes such as to support team learning, to in...

Parameter estimation is a key problem in the development of process models, both steadyand unsteadystate, and thus is an important issue in both process design and control. The error-in-variable approach differs distinctly from the standard approach in that measurement errors in both dependent and independent system variables are taken into account when formulating the objective function in the...

Reverse algorithm was previously evaluated as encryption method concluding that its simple adoption is unviable, since it does not assurance the pre-image existence. Variable-Length Encryption Method (VLE) was proposed where a alternative algorithm with extra bits is adopted when pre-image computation is not possible. If an adequate secret key is used with VLE it is expected that the final ciph...

Frog Virtual Learning Environment (VLE) is used to enhanced teaching and learning in Malaysia government public schools since 2012. VLE has become the main mechanism in supporting on-line education in primary and secondary schools in Malaysia. Thus, Frog VLE was introduced by Malaysia’s Ministry of Education (MoE) as a tool to support student’s learning which evolved from the 1Bestari Net Proje...
