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 ...
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 ...
eCos. The Embedded Configurable Operating System ( eCos) is a free and open-source real-time operating system intended for embedded systems and applications which need only one process with multiple threads. It is designed to be customizable to precise application requirements of run-time performance and hardware needs.
The VLE concentration data can be determined experimentally or approximated with the help of theories such as Raoult's law, Dalton's law, and Henry's law. Such vapor–liquid equilibrium information is useful in designing columns for distillation , especially fractional distillation , which is a particular specialty of chemical engineers.
Sakai (software) Sakai is a free, community-driven, open source educational software platform designed to support teaching, research and collaboration. Systems of this type are also known as learning management systems (LMS), course management systems (CMS), or virtual learning environments (VLE). Sakai is developed by a community of academic ...
In order for hard real-time systems be sufficiently exact in their timing, often they are just a library with no protection between applications, such as eCos. Virtual machine. A virtual machine is an operating system that runs as an application on top of another operating system.
The VIRTUS project at University of Cologne, Germany, has started the development of the web-based ILIAS learning management system in 1997. A first version with an integrated web-based authoring environment has been going online at 2 November 1998. In 2000 ILIAS became open source software under the GPL.
VLE of the mixture of chloroform and methanol plus NRTL fit and extrapolation to different pressures. The non-random two-liquid model (abbreviated NRTL model) is an activity coefficient model introduced by Renon and Prausnitz in 1968 that correlates the activity coefficients of a compound with its mole fractions in the liquid phase concerned.
