Self-call - a Message from an Object to one of its own Methods Sequence diagram - describes the Messages sent between a number of participating Objects in a Scenario Signal - an Event which can occur in an Activity diagram in three different ways: as a Time Signal, as a signal which an Activity can listen for and a signal which an Activity can send
The diagram emphasizes events that cross the system boundary from actors to systems. A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD): A regular version of sequence diagram describes how the ...
Attention is a machine learning method that determines the relative importance of each component in a sequence relative to the other components in that sequence. In natural language processing , importance is represented by "soft" weights assigned to each word in a sentence.
The main diagonal represents the sequence's alignment with itself; lines off the main diagonal represent similar or repetitive patterns within the sequence. In bioinformatics a dot plot is a graphical method for comparing two biological sequences and identifying regions of close similarity after sequence alignment. It is a type of recurrence plot.
A diagram is a partial graphic representation of a system's model. The set of diagrams need not completely cover the model and deleting a diagram does not change the model. The model may also contain documentation that drives the model elements and diagrams (such as written use cases). UML diagrams represent two different views of a system ...
In addition, other behavioral UML diagrams such as activity diagrams, sequence diagrams, communication diagrams, and state machine diagrams can also be used to visualize use cases accordingly. Specifically, a System Sequence Diagram (SSD) is a sequence diagram often used to show the interactions between the external actors and the system under ...
An alternative deals with two possibles responses: 1 - The timer goes off because the switch did not reply and the phone goes back to the disconnected state.2 - The switch grants the connection and the call is established. A message sequence chart (or MSC) is an interaction diagram from the SDL family standardized by the International ...
The observer design pattern is a behavioural pattern listed among the 23 well-known "Gang of Four" design patterns that address recurring design challenges in order to design flexible and reusable object-oriented software, yielding objects that are easier to implement, change, test and reuse.
