ÐIn this paper, an empirical study that links software process consistency with product defects is reported. Various measurement issues such as validity, reliability, and other challenges in measuring process consistency at the project level are discussed. A measurement scale for software process consistency is introduced. An empirical study that uses this scale to measure consistency in achiev...

This article presents an arc-consistency algorithm for the tree constraint, which enforces the partitioning of a digraph G = (V, E) into a set of vertex-disjoint anti-arborescences. It provides a necessary and sufficient condition for checking the tree constraint in O(|V| + |E|) time, as well as a complete filtering algorithm takingO(|V| · |E|) time.

Dynamically composed systems are able to incorporate new components as they execute. Therefore, conngurations of these systems are not fully elaborated until at least the time that they are executed, and they are perhaps never fully elaborated. Such incomplete conngurations are termed partially bound conngurations. Although partially bound, it is still important to be able to analyse these conn...

COMIX (COnfiguration of MIXing machines) is a system that assists members of the sales department of EKATO in designing a mixing machine which fulfills the requirements of a customer. It is used to help the engineer design the requested machine and prepare an offer that’s to be submitted to the customer. COMIX integrates more traditional software techniques with explicit knowledge representatio...

for a finite group $g$‎, ‎let $cent(g)$ denote the set of centralizers of single elements of $g$‎. ‎in this note we prove that if $|g|leq frac{3}{2}|cent(g)|$ and $g$ is 2-nilpotent‎, ‎then $gcong s_3‎, ‎d_{10}$ or $s_3times s_3$‎. ‎this result gives a partial and positive answer to a conjecture raised by a‎. ‎r‎. ‎ashrafi [on finite groups with a given number of centralizers‎, ‎algebra‎ ‎collo...

This paper specifically addresses the question of polysemy with respect to verbs, and whether or not the sense distinctions that are made in on-line lexical resources such as WordNet are appropriate for computational lexicons. The use of sets of related syntactic frames and verb classes are examined as a means of simplifying the task of defining different senses, and the importance of concrete ...

A large number of features have been proposed by researchers for on-line signature verification. However, little work has been done in measuring the consistency and discriminative power of these features. This paper presents a comparative study of features commonly used in on-line signature verification. A consistency model is developed by generalizing the existing feature-based measure to dist...

Original crystal structures of even–even polyamides are introduced. They based on twisted conformations at the amide-aliphatic part links and reminiscent pleated rippled protein sheet introduced by Pauling Corey in early 1950s. Pleated sheets chiral, made two conformational isomers. have specific X-ray diffraction “profiles”. Publications describe such profiles, indicating that both variants ex...
