PlantUML is an open-source tool allowing users to create diagrams from a plain text language. Besides various UML diagrams, PlantUML has support for various other software development related formats (such as Archimate, Block diagram, BPMN, C4, Computer network diagram, ERD, Gantt chart, Mind map, and WBD), as well as visualisation of JSON and YAML files.
Includes glossary, data dictionary, and issue tracking. Supports use case diagrams, auto-generated flow diagrams, screen mock-ups, and free-form diagrams. clang-uml: Unknown Unknown Unknown Unknown No C++ PlantUML, Mermaid.js Generate PlantUML and Mermaild.js diagrams from existing C++ codebase. Dia: Partly No No No
In the Stückelberg–Feynman interpretation, pair annihilation is the same process as pair production. Møller scattering. electron-electron scattering. Bhabha scattering. electron-positron scattering. Penguin diagram. a quark changes flavor via a W or Z loop. Tadpole diagram. One loop diagram with one external leg.
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate. It requires selecting and identifying relevant aspects of a situation in the real world and then developing ...
e. In physics, a one-loop Feynman diagram is a connected Feynman diagram with only one cycle (unicyclic). Such a diagram can be obtained from a connected tree diagram by taking two external lines of the same type and joining them together into an edge. Diagrams with loops (in graph theory, these kinds of loops are called cycles, while the word ...
Penguin diagram. Example of a penguin diagram superimposed on an image of a Gentoo penguin. In quantum field theory, penguin diagrams are a class of Feynman diagrams which are important for understanding CP violating processes in the standard model. They refer to one-loop processes in which a quark temporarily changes flavor (via a W or Z loop ...
The random phase approximation (RPA) is an approximation method in condensed matter physics and in nuclear physics. It was first introduced by David Bohm and David Pines as an important result in a series of seminal papers of 1952 and 1953. [1][2][3] For decades physicists had been trying to incorporate the effect of microscopic quantum ...
