Laws of Pattern Composition

چکیده
Design patterns are rarely used on their own. They are almost always to be found composed with each other in real applications. So it is crucial that we can reason about their compositions. In our previous work, we defined a set of operators on patterns so that pattern compositions can be represented as expressions on patterns. In this paper, we investigate the algebraic properties of these operators, prove a set of algebraic laws that they obey, and use the laws to show the equivalence of pattern compositions.

Local Derivative Pattern with Smart Thresholding: Local Composition Derivative Pattern for Palmprint Matching
Palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. Texture is one of the most important features extracted from low resolution images. In this paper, a new local descriptor, Local Composition Derivative Pattern (LCDP) is proposed to extract smartly stronger...

متن کاملContinuation Semantics for Concurrency
This paper presents a continuation semantics satisfying the basic laws of concurrent systems. This semantics is illustrated for a simple CSP-like language extended with communication on multiple channels and synchronization based on join patterns, which also provides operators for nondeterministic choice, sequential and parallel composition. For the language under investigation we present a den...
