Java Model Railroad Interface (JMRI) is an open source program for model railroad hobbyists, released under GNU General Public License v2. It allows users to control LED lights, horn, or switch the railway of hobbyist open-source or commercials closed-sourced trains. JMRI is a suite of tools distributed via a single download.
OpenQM is a multivalue database, and, as such, shares many aspects in common with similar Pick-descended databases. It also has a number of features not found in most other commercial MV databases, such as auto-sizing of database files, 'binary clean' execution of QMBasic, and, perhaps uniquely in the MV world, object, class and exception handling support in Basic.
Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).
Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on model railways. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still ...
Märklin Digital was among the earlier digital model railway control systems. It was a comprehensive system including locomotive decoders (based on a Motorola chip), central control (Märklin 6020/6021), a computer interface (Märklin 6050), turnout decoders (Märklin 6083), digital relays (Märklin 6084) and feedback modules (Märklin s88/6088).
The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...
The model–view–controller (MVC) pattern is the fundamental structure to organize application programming.. In a default configuration, a model in the Ruby on Rails framework maps to a table in a database and to a Ruby file.
Trainz is a series of 3D train simulator video games.The Australian studio Auran (since 2007 N3V Games) released the first game in 2001.. The simulators consist of route and session editors called Surveyor, and a Driver module that loads a route and lets the player operate and watch the trains run in either "DCC" mode, which simulates a bare-bones Digital Command Control (DCC) system for the ...
