A sequence diagram shows, as parallel vertical lines ( lifelines ), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them in the order in which they occur. This allows for the graphical specification of simple runtime scenarios. A system sequence diagram should specify and show ...
A work breakdown structure permits the summing of subordinate costs for tasks, materials, etc., into their successively higher level "parent" tasks, materials, etc. For each element of the work breakdown structure, a description of the task to be performed is generated. [ 7] This technique (sometimes called a system breakdown structure[ 8]) is ...
In mathematics, the lexicographic or lexicographical order (also known as lexical order, or dictionary order) is a generalization of the alphabetical order of the dictionaries to sequences of ordered symbols or, more generally, of elements of a totally ordered set . There are several variants and generalizations of the lexicographical ordering.
A Sequence Flow is represented with a solid line and arrowhead, and shows in which order the activities are performed. The sequence flow may also have a symbol at its start, a small diamond indicates one of a number of conditional flows from an activity, while a diagonal slash indicates the default flow from a decision or activity with ...
The Structural Classification of Proteins extended (SCOPe) database was released in 2012 with far greater automation of the same hierarchical system and is full backwards compatible with SCOP version 1.75. In 2014, manual curation was reintroduced into SCOPe to maintain accurate structure assignment.
In software engineering , a class diagram[ 1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
The Sun is found on the main sequence at luminosity 1 (absolute magnitude 4.8) and B−V color index 0.66 (temperature 5780 K, spectral type G2V). The Hertzsprung–Russell diagram (abbreviated as H–R diagram , HR diagram or HRD ) is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities and ...
In linguistics, morphology ( mor-FOL-ə-jee[ 1]) is the study of words, including the principles by which they are formed, and how they relate to one another within a language. [ 2][ 3] Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning.
