The Model V was among the early [2] electromechanical [3] general purpose computers, [4] [5] [6] designed by George Stibitz and built by Bell Telephone Laboratories, operational in 1946. Only two machines were built: first one was installed at National Advisory Committee for Aeronautics (NACA, later NASA), the second (1947) at the US Army’s ...
The two-stage valve-lift function is performed by electro-hydraulically operated switchable tappets. Each of these 12 tappets consists of concentric lifters which can be locked together by means of a pin. The inner lifter is actuated by a small cam lobe, while the outer ring element is moved by a pair of larger-profile lobes.
Vehicles specifically designed or adapted for the Signal Corps were initially designated by a "K" number. The K-number was later phased out along with the Signal Corps Radio nomenclature system, and was replaced by a "V" number under the Joint Electronics Type Designation System (JETDS).
The Red Army adopted the V-2 engine in the same year in three modifications: the V-2 (500 hp (370 kW)), the V-2K (600 hp (450 kW)) for the KV line of tanks and the V-2V (375 hp (280 kW)). [ 1 ] Near the end of the 20th century, the V-2 was fitted with more modern modifications by the chief designer of the head design bureau for the Chelyabinsk ...
The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
The theory of constraints (TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it.
This page lists vans currently in production (as of 2013) as well as past models. Unlike a pickup truck, The list includes minivans, passenger vans and cargo vans.. Note: Many of the vehicles (both current and past) are related to other vehicles in the list.
A modified variant of the V, the F, was the first aircraft to fly with the new Liberty L-12 engine that would find widespread use in the latter part of World War One.The model F in turn led to the "Reconnaissance", an intended production variant of the F, which in turn evolved into the LWF model G, although none of these would see large scale production.
