With increasing importance placed on standard quality assurance methodologies by large companies and government organizations, many software companies have implemented rigorous quality assurance (QA) processes to ensure that these standards are met. The satisfaction of these quality checks ensures that the software has achieved a certain level of compliance to standards and thereby gives the co...

Quality assurance (QA) of the multileaf collimator (MLC) is a critical step for the delivery of intensity modulated radiation therapy treatment plan. While QA procedures for motor-driven MLC have been published extensively, those for binary MLCs such as the one used for helical tomotherapy have not been presented in the literature, as this is still a fairly new technology. In this study, seven ...

CBSD Technique is based on the idea to develop software systems by selecting appropriate off-theshelf components and then to join them with a well-defined software structure. Because the new software development paradigm is more different from the traditional approach, quality assurance (QA) for CBSD is a new topic in the software engineering community. We survey current component-based softwar...

The design quality assurance (QA) process impacts the engineering design performance in many aspects, such as in design process cycle time, rework cost, customer satisfaction, etc. Thereby it is necessary to develop systematic methods and tools for modelling, analysing and improving design QA processes. This report addresses three aspects of QA processes: a process representation approach; a DS...

Clients of outsourced databases need Query Authentication (QA) guaranteeing the integrity (correctness and completeness), and authenticity of the query results returned by potentially compromised providers. Existing results provide QA assurances for a limited class of queries by deploying several software cryptographic constructs. Here, we show that, to achieve QA, however, it is significantly ...

The philosophy of quality assurance (QA) and total quality management is derived from industrial and commercial practice. We propose the adoption of international standards ISO 9000 (used in industry and commerce) to higher educational institutions to assure and improve the quality, efficiency, and delivery of their programmes and services. This paper examines the scope and structure of a QA sy...

Open-source development processes have emerged as an effective approach to reduce cycle-time and decrease design, implementation, and quality assurance costs for certain types of software, particularly systems infrastructure software, such as operating systems, compilers and language processing tools, text and drawing editors, and middleware. This paper presents two contributions to the study o...

The Software Product Lines (SPLs) paradigm promises faster development cycles and increased quality by systematically reusing software assets. This paradigm considers a family of systems, each of which can be obtained by a selection of features in a variability model. Though essential, providing Quality Assurance (QA) techniques for SPLs has long been perceived as a very difficult challenge due...

Detection and accurate quantification of treatment delivery errors is important in radiation therapy. This study aims to evaluate the accuracy of DVH based QA in quantifying delivery errors. Eighteen previously treated VMAT plans (prostate, H&N, and brain) were randomly chosen for this study. Conventional IMRT delivery QA was done with the ArcCHECK diode detector for error-free plans and plans ...
