This article uses data from an action research project (ARP) conducted with part-time higher education (HE) students as a means of exploring the recent thinking about learning characterised by theories connectivism. Both quantitative and qualitative are presented to assess extent which connectivist theory might explain – indeed develop use virtual environment (VLE) on Education degree in United...

vapor-liquid equilibrium in nh3-co2-h2o system at high pressures has been studied. the uniquac-nrf model for this system was extended by using the goppert 4 maurer reported datas. since the system contains molecules and ionic species the binary interaction parameters considered, where those are of molecule-molecule, molecule-ion and ion-ion types. these interaction parameters are taken as const...

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 this ...

The identification of the correct thermodynamic states forming in supercritical mixing and combustion is an important area research engineering. When a multi-component mixture evolves at pressures that are higher than critical each individual component, real-gas (RG) equation state (EoS) must be used order to achieve superior accuracy predictions. However, this may not enough when complex non-l...

The adoption of virtual learning environment (VLE) has started to gain serious attention worldwide including Malaysia, where its usage during the Covid-19 pandemic outbreak become a necessity. Nevertheless, extent which teachers have adopted VLE and factors are most influencing continuance intention adopt post remain ambiguous. objective this conceptual study is provide framework in investigati...
