A pie chart or a circle graph is a circular chart divided into sectors, illustrating numerical proportion. In a pie chart, the arc length of each sector and consequently its central angle and area, is proportio
The Z notation was used to write the specifications, it has proved apt for the purpose, enabling one to write succinct specifications in terms of a basic definition of a flowgraph.doi:10.1016/0950-5849(88)90040-7NE FentonPDA MoleElsevier B.V.Information and Software Technology...
DFDs debuted in software engineering in the late '70s, making them a precursor to UMLs. DFDs were popularized by the bookStructured Design,written by computer professionals Larry Constantine and Ed Yourdon, which was in turn inspired by the data flow graph computation models of David Martin and ...
“data flow graph” computation models by David Martin and Gerald Estrin. The structured design concept took off in the software engineering field, and the DFD method took off with it. It became more popular in business circles, as it was applied to business analysis, than in academic circles...

The execution time of a high-performance computing algorithm is influenced by various factors, including the algorithm's scalability, the selected hardware for processing elements, and the communication speed between these elements. This study utilizes a
Die Notation 4.1. Datenströme Abbildung 4.1.: Datenfluss zwischen drei Funktionseinheiten Über den Pfeilen, die die Richtung der Datenflüsse darstellen, werden die im Datenfluss enthaltenen Daten in runden Klammern eingetragen. Eine leere Klammer bedeutet, dass ein Datenstrom ohne Daten ...
showed how, given a handful of simple operators and a notation for functions, you can build a whole programming language. [McCarthy’s] ideas are still the semantic core of Lisp today. It’s not something that McCarthy designed so much as something he discovered. It’s not intrinsically a...
For a control flow graph G = {V, E}, where V = {vi|i∈ {0, 1, …, N − 1}}. In its equivalent bipartite graph BG, vi corresponds to two sub-blocks viu∈ U, viw∈ W. We change the notation viu to v2i and viw to v2i + 1 for mapping the indices. Thus, all elements...
