in zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. the proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be appl...

Despite the increasing importance of data and information quality, current research related to Big Data quality is still limited. It is particularly unknown how to apply previous data quality models to Big Data. In this paper we review Big Data quality research from several perspectives and apply a known quality model with its elements of conformance to specification and design in the context o...

This paper models the video quality, which focuses on the effects of computation precision by combining subjective-objective metric. The motivation behind the research is to bring quality-driven design into effect for video applications. We change the computation-precision of IDCT, the kernel program of MPEG-2 video decoder and get the experimental computation-precision-oriented video quality m...

Making justifiable decisions is a critical aspect of software architecture design. However, there has been limited empirical research on the effects of design reasoning on the quality of software design. The goal of this work is to investigate if there is any quality improvement to software design when design reasoning is applied. We conducted an empirical study involving twenty designers, the ...

This paper mainly studies the effect of design patterns on the Software maintainability. Design patterns describe solutions for common design problems and they were introduced to improve software quality and accelerate software development. However, there are some difficulties to choose an optimal pattern adapted to a certain application and problem. So until now the results on the effect of de...

Testability is a software quality characteristic that is of major relevance for test costs and software dependability. Still, testability is not an explicit focus in today’s industrial software development projects. Related processes, guidelines, and tools are missing. This paper is about design for testability, the main intersection of software design and testing. We describe 1) elements of ob...
