The 4D/RCS Reference Model Architecture is a reference model for military unmanned vehicles on how their software components should be identified and organized. The 4D/RCS has been developed by the Intelligent Systems Division (ISD) of the National Institute of Standards and Technology (NIST) since the 1980s.
Imagix 4D is a source code analysis tool from Imagix Corporation, used primarily for understanding, documenting, and evolving existing C, C++ and Java software. [ 1 ] Applied technologies include full semantic source analysis.
Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
The homotopy type of a simply connected compact 4-manifold only depends on the intersection form on the middle dimensional homology. A famous theorem of Michael Freedman () implies that the homeomorphism type of the manifold only depends on this intersection form, and on a / invariant called the Kirby–Siebenmann invariant, and moreover that every combination of unimodular form and Kirby ...
Eight Disciplines Methodology (8D) is a method or model developed at Ford Motor Company used to approach and to resolve problems, typically employed by quality engineers or other professionals. Focused on product and process improvement, its purpose is to identify, correct, and eliminate recurring problems. [ 1 ]
4D BIM, an acronym for 4-dimensional building information modeling, refers to the intelligent linking of individual 3D CAD components or assemblies with time- or scheduling-related information. [ 35 ] [ 137 ] The term 4D refers to the fourth dimension : time , i.e. 3D plus time.
Appreciative inquiry (AI) is a model that seeks to engage stakeholders in self-determined change.According to Gervase Bushe, professor of leadership and organization development at the Beedie School of Business and a researcher on the topic, "AI revolutionized the field of organization development and was a precursor to the rise of positive organization studies and the strengths based movement ...
By comparison, based on the concept of attractor coexistence within the generalized Lorenz model [26] and the original Lorenz model ([36] [37]), Shen and his co-authors [35] [38] proposed a revised view that “weather possesses both chaos and order with distinct predictability”. The revised view, which is a build-up of the conventional view ...
