Data, context and interaction. Data, context, and interaction ( DCI) is a paradigm used in computer software to program systems of communicating objects. Its goals are: To improve the readability of object-oriented code by giving system behavior first-class status; To cleanly separate code for rapidly changing system behavior (what a system ...
Early patterns with unknown futures, such as the R-pentomino, led computer programmers to write programs to track the evolution of patterns in the Game of Life. Most of the early algorithms were similar: they represented the patterns as two-dimensional arrays in computer memory. Typically, two arrays are used: one to hold the current generation ...
An interface control document ( ICD) in systems engineering [1] and software engineering, provides a record of all interface information (such as drawings, diagrams, tables, and textual information) generated for a project. [2] The underlying interface documents provide the details and describe the interface or interfaces between subsystems or ...
Abstraction (computer science) In software engineering and computer science, abstraction is the process of generalizing concrete details, [1] such as attributes, away from the study of objects and systems to focus attention on details of greater importance. [2] Abstraction is a fundamental concept in computer science and software engineering ...
In many cases, they generally offer greater simplicity of implementation over a block code of equal power. The encoder is usually a simple circuit which has state memory and some feedback logic, normally XOR gates. The decoder can be implemented in software or firmware. The Viterbi algorithm is the optimum algorithm used to decode convolutional ...
In digital circuit design, register-transfer level ( RTL) is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals ( data) between hardware registers, and the logical operations performed on those signals. Register-transfer-level abstraction is used in hardware description languages (HDLs) like ...

The perceptual computer – Per-C – an instantiation of perceptual computing – has the architecture that is depicted in Fig. 1 [2]– [6]. It consists of three components: encoder, CWW engine and decoder. Perceptions – words – activate the Per-C and are the Per-C output (along with data); so, it is possible for a human to interact with ...
