The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.
Transmission internals for a 2009 Volkswagen Golf. A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.
In lean software development, pull scheduling with Kanban provides short term time management. When developing a large and complex system, where long term planning is required, timeboxing is layered above. [15] Rapid application development (RAD) software development process features iterative development and software prototyping.
The Putnam model is an empirical software effort estimation model [1] created by Lawrence H. Putnam in 1978. Measurements of a software project is collected (e.g., effort in man-years, elapsed time, and lines of code) and an equation fitted to the data using regression analysis .
In order to enable the project team to run a successful project, they also need the appropriate technology to conduct the project. This means a development environment, project management tools, etc. Factor 4: Finally, DSDM also states that a supportive relationship between customer and vendor is required.
The expansion of the model to a dual-Vee concept is treated in reference. [3] As the V-model is publicly available many companies also use it. In project management it is a method comparable to PRINCE2 and describes methods for project management as well as methods for system development. The V-model, while rigid in process, can be very ...
The involute gear profile, sometimes credited to Leonhard Euler, [1] was a fundamental advance in machine design, since unlike with other gear systems, the tooth profile of an involute gear depends only on the number of teeth on the gear, pressure angle, and pitch. That is, a gear's profile does not depend on the gear it mates with.
