Software quality is an important issue in the development of successful software application. Many methods have been applied to improve the software quality. Refactoring is one of those methods. But, the effect of refactoring in general on all the software quality attributes is ambiguous. The goal of this paper is to find out the effect of various refactoring methods on quality attributes and t...

The attribute Conforming Run Length (CRL) control chart has attracted increasing research interests in Statistical Process Control (SPC). It decides the process status based on the interval or distance between two nonconforming units. This article proposes a Generalized CRL chart (namely GCRL chart) for monitoring the mean of a measurable quality characteristic x under 100% inspection. To run a...

Attribute sampling is a powerful quality inspection tool. The Lot Acceptance Sampling Plans (LASPs) for sampling by attributes represent a valuable method of quality inspection. Significant LASPs such as the c=0, Dodge-Romig, Philips as well as ANSI/ASQC Z1.4 which replaced MIL-STD 105E have comprehensive procedures and statistical base. A single LASP can be implemented efficiently if inspectio...

Capturing data quality and context semantics at the early stage of database design is a critical issue for both database researchers and practitioners. As in traditional database design, users' quality and context requirements should be represented at the conceptual level. This paper first generalizes the issues governing data quality and context semantics to be an Interattribute-Relationship p...
