A learning management system (LMS) or virtual learning environment (VLE) is a software application for the administration, documentation, tracking, reporting, automation, and delivery of educational courses, training programs, materials or learning and development programs. [1] The learning management system concept emerged directly from e ...
Vapor–liquid equilibrium. In thermodynamics and chemical engineering, the vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase. The concentration of a vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be ...
Tandata Td1400 Prestel terminal. A Virtual Learning Environment (VLE) is a system specifically designed to facilitate the management of educational courses by teachers for their students. It predominantly relies on computer hardware and software, enabling distance learning. In North America, this concept is commonly denoted as a "Learning ...
Image is rotating to more clearly show the saddle-like shape of the vapor–liquid equilibria. In statistical thermodynamics, the UNIFAC method (UNI QUAC F unctional-group A ctivity C oefficients) [1] is a semi-empirical system for the prediction of non-electrolyte activity in non- ideal mixtures. UNIFAC uses the functional groups present on ...
Blackboard Learn (previously the Blackboard Learning Management System) is a web-based virtual learning environment and learning management system developed by Blackboard Inc. The software features course management, customizable open architecture, and scalable design that allows integration with student information systems and authentication ...
Distance education. Distance education, also known as distance learning, is the education of students who may not always be physically present at school, [1][2] or where the learner and the teacher are separated in both time and distance. [3] Traditionally, this usually involved correspondence courses wherein the student corresponded with the ...
