The current trend of education is towards the implementation technology in teaching order to attract attention 21st century learners whereby teachers need adopt technology-enhanced environment such as Virtual Learning Environment (VLE) their teaching. This study aims investigate teachers’ perceptions and tendency use VLE a tool for were investigated based on main constructs Technology Acceptanc...

The objective of this article is to present the creation process Pedagogical Strategies (PS) based on Socio-affective Scenarios mapped in a Virtual Learning Environment (VLE). Every year, enterprises are looking for new technologies that can improve skills their collaborators, bringing VLE resources e-training formations. PSs actions carried out by professors or manager practice, both e-learnin...

A method based on the Genetic Algorithm (GA) was developed to study the phase behavior of multicomponent and multiphase systems. Upon application of the GA to the thermodynamic models which are commonly used to study the VLE, VLLE and LLE phase equilibria, the physically meaningful values for the Binary Interaction Parameters (BIP) of the models were obtained. Using the method proposed in t...

in this paper, the vapor-liquid equilibrium (vle) properties of polar and nonpolar fluids are modeled by the use of a statistically-based equation of state (eos). the equation of state used in this work is that of ihm-song-mason (ism) eos. an alternative approach is to revise the isothermal integration on liquid. in this respect, a temperature-dependent revision factor b (t) is introduced to th...

This work studies two binary mixtures of R1243zf + R1234yf and R245cb which can be possibly used as a long-term alternative refrigerant for heat pumps. We present critical property (critical temperature, pressure, density) vapor liquid equilibrium (VLE) binaries. The maximum extended uncertainties (k=2) are estimated U(T) = 0.21 K, U(p) 0.048 MPa, U(ρ) 6.4 kg/m3 measurement, 0.06 K 0.015 MPa bu...

In this work, new experimental data on thermodynamic properties of ionic liquid (IL) aqueous solutions are presented. The (vapor + liquid) phase equilibria, density, and dynamic viscosity binary mixtures composed N,N-diethyl-N-methylammonium bromide ([NH,1,2,2][Br]), or methanesulfonate ([NH,1,2,2][CH3SO3]) water presented as functions temperature composition. Both ILs were synthesized specific...

The general set of HCI and Educational principles are considered and a classification system constructed. A frequency analysis of principles is used to obtain the most significant set. Metrics are devised to provide objective measures of these principles and a consistent testing regime devised. These principles are used to analyse Blackboard and Moodle.
