We examine the functional cohesion of procedures using a data slice abstraction. Our analysis identi es the data tokens that lie on more than one slice as the \glue" that binds separate components together. Cohesion is measured in terms of the relative number of glue tokens, tokens that lie on more than one data slice, and super-glue tokens, tokens that lie on all data slices in a procedure, an...

This paper proposes a set of new static metrics of coupling and cohesion developed to assess the reusability of Java components retrieved from the Internet by a software component search engine. These metrics differ from the majority of established metrics in three respects: they measure the degree to which entities are coupled or resemble each other, they quantitatively take account of indirec...

the redundancy allocation problem can be described as selecting the components and system configuration in order to optimize some objective function(s) without violating the system constraints. operating conditions are not constant in many advanced engineering systems. mostly, in the engineering applications selection, the number of redundancy components must be balanced among the constraints (...

Many coupling and cohesion measures have been introduced in various surveys to identify and measure the design complexity of object oriented systems. A large numbers of metrics have been built and proposed for measuring properties of object-oriented software such as size, inheritance, cohesion and coupling. The coupling is an important aspect in the evaluation of reusability and maintainability...

Background: Fritillaria imperialis is an endangered species with pharmaceutical alkaloids that can be effective in reducing blood pressure and reducing cardiac palpitations.   Objective: Comparison of head space solid phase microextraction (HS-SPME) and hydro-distillation (HD) techniques in determination of essential oils in Fritillaria imperialis Methods: Quality and quantity determination o...

Group cohesion in sport is a widely spread theme today. Research has found cohesion to be influenced by several individual and group components. Among the cognitive variables that relate to cohesion we found competitive anxiety. The purpose of this study was to examine the relation between task cohesion (ATG-T, and GI-T) and competitive state anxiety (A-state), and also if there would be a rela...

Creating an efficient and effective system is a motto of a software engineer. The companies are spending 60% of cost for producing good quality software, software metrics require to measure qualitative in terms of software performance and reliability related characteristics like dependencies, coupling and cohesion etc. This paper proposes a set of new measures to find coupling and cohesion in a...

High cohesion, or module strength, indicates that a system has been well partitioned into components which have strong internal relationships. An understanding of cohesion is an important factor in software design. However, cohesion is difficult to define precisely and to quantify, particularly for object oriented (OO) software, and attempts to develop metrics have had limited success. We advoc...
