Software architecture evaluation has been widely accepted as a powerful means to mitigate risks in the design and evolution of software systems. To date we have conducted more than 75 architecture evaluation projects with industrial customers in the past decade. One recurring lesson learned that we experienced across many architecture evaluation projects is that maintainability indeed is a vers...

Whenever an architect or a team of architects begins an architectural design, there are certain goals set to achieve. There are many factors involved in setting up goals for the architecture design such as type of the project, end user perspective, functional and nonfunctional requirements and so on. This paper reviews and further elaborates strategy for the usability characteristics of softwar...

Introduction: The evaluation of X-ray and light field coincidence in linear accelerators as a quality control test is often performed subjectively, involving the manual marking of films and their visual inspection following the irradiation. Therefore, the present study aimed to develop an objective method for the performance of this test leading to the increased levels...

Software variability has received research attention. However, only a few studies address the issue of quality attribute variability within software product families. This paper describes the ongoing research on quality attribute variability within a software product family architecture. We motivate the research topic by identifying three different situations in which quality attributes may var...

background: quality assurance in the hematology laboratory is a must to ensure laboratory users of reliable test results with high degree of precision and accuracy. even after so many advances in hematology laboratory practice, pre-analytical errors remain a challenge for practicing pathologists. this study was undertaken with an objective to evaluate the types and frequency of preanalytical er...

Class cohesion is an important object-oriented software quality attribute. It indicates how much the members in a class are related. Assessing the class cohesion and improving the class quality accordingly during the object-oriented design phase allows for cheaper management of the later phases. In this paper, the notion of distance between pairs of methods and pairs of attribute types in a cla...

The VCG mechanism is the standard method to incentivize bidders in combinatorial auctions to bid truthfully. Under the VCG mechanism, the auctioneer can sometimes increase revenue by “burning” items. We study this phenomenon in a setting where items are described by a number of attributes. The value of an attribute corresponds to a quality level, and bidders’ valuations are non-decreasing in th...

nitrofurazone is one of the antibacterial nitrofuran agents used topically for skin infections. the drug is effective on the majority of infectious microorganisms. because of the importance of this drug in clinic, in this study various methods of synthesis of nitrofurazone were examined and the most appropriate method, applicable to pharmaceutical industry was chosen and optimized from the poin...
