Use case diagram. v. t. e. A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses.
Ellingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of Δ G, the Gibbs free energy change, which is equal to Δ H − T Δ S, where Δ H is the enthalpy change and Δ S is the entropy change. The Ellingham diagram plots the Gibbs free energy change (Δ G) for ...
The TAS classification can be used to assign names to many common types of volcanic rocks based upon the relationships between the combined alkali and silica contents. These chemical parameters are useful because the relative proportions of alkalis and silica are important in determining both normative mineralogy and actual mineralogy.
Diagram. A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. [1] Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface.
Hyperosmolar Hyperglycemic Syndrome (HHS) High blood sugar (hyperglycemia) can cause very serious problems, too.HHS isn't as common as DKA, but it's more dangerous. It's a complication of type 2 ...
If left untreated, the condition can lead to cataracts, increasing weakness in the legs (neuropathy), malnutrition, ketoacidosis, dehydration, and death. [2] Diabetes mainly affects middle-aged and older dogs, but there are juvenile cases. [3] [4] [5] The typical canine diabetes patient is middle-aged, female, and overweight at diagnosis.
A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. [1] It displays the signal as a two-dimensional xy -plane scatter diagram in the complex plane at symbol sampling instants. In a manner similar to that of a phasor diagram, the angle of ...
diagrams.net (previously draw.io) is a cross-platform graph drawing software developed in HTML5 and JavaScript. Its interface can be used to create diagrams such as flowcharts , wireframes , UML diagrams, organizational charts , and network diagrams .
