Exploring Organizations’ Software Quality Assurance Strategies by Scott Underwood MBA, University of Fredericton, 2010 Doctoral Study Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Business Administration Walden University September 2016 Abstract Poor software quality leads to lost profits and even loss of life. U.S. organizations lose billions of dollars annua...

background iran has a widespread diagnostics and clinical support services (dcss) network that plays a crucial role in providing diagnostic and clinical support services to both inpatient and outpatient care. however, very little is known on the application of quality assurance (qa) policies in dcss units. this study explores the extent of application of eleven qa strategies in dcss units withi...

This article examines the issues of learning engagement and describes the socio-cultural context of Quest Atlantis’ (QA) implementation in a series of science lessons among primary Four (10 to 11 years old) students in Singapore. QA is a Multi-user Virtual Environment (MUVE). It uses 3D virtual technology to create an interactive environment to immerse children aged between 8 and 12 years in ed...

The traditional model of information retrieval entails some implicit restrictions, including: a) the assumption that users search for documents, not answers; and that the documents per se will respond to and satisfy the query, and b) the assumption that the queries and the document that will satisfy the particular informational need are written in the same language. However, many times users wi...

The new DIN ('Deutsche Industrie-Norm') 6875-1, which is currently being finalised, deals with quality assurance (QA) criteria and tests methods for linear accelerator and Gamma Knife stereotactic radiosurgery/radiotherapy including treatment planning, stereotactic frame and stereotactic imaging and a system test to check the whole chain of uncertainties. Our existing QA program, based on dedic...

We participated in NTCIR-8 CCLQA Task for Chinese-to-Chinese (C-C) and English-to-Chinese (E-C) tasks. This is our first time developing a QA system for complex questions, although we already have some experiences on handling BIOGRAPHY, DEFINITION, and WHY questions. This paper provides the description of our complex QA system, the NTOU XQA System participated in NTCIR-8 CCLQA Task. This QA sys...

Mobius FX, an add-on software module from Mobius Medical Systems™ for intensity-modulated radiation therapy (IMRT) quality assurance (QA), uses linac treatment logs to efficiently calculate and verify the 3D dose delivered to patients. An advantage of the Mobius FX module is that it does not require device positioning. In this study, we compared the Mobius FX with another QA option, ArcCheck, a...

An ensemble of genetic networks that describe how the model fungal system, Neurospora crassa, utilizes quinic acid (QA) as a sole carbon source has been identified previously. A genetic network for QA metabolism involves the genes, qa-1F and qa-1S, that encode a transcriptional activator and repressor, respectively and structural genes, qa-2, qa-3, qa-4, qa-x, and qa-y. By a series of 4 separat...

The qa-1 regulatory region controls the expression of the three structural genes required for the early reactions in quinic acid catabolism in Neurospora crassa. Genetic analysis previously identified two types of noninducible qa-1 mutants, qa-1S and qa-1F, which mapped in separate non-overlapping regions. These mutations were originally interpreted as defining separate domains of a single regu...

Gene replacement by transformation, employing selective genetic recombination techniques, has been used to delete or disrupt the qa-x, qa-y and qa-1S genes of the qa gene cluster of Neurospora crassa. The growth characteristics of the strain carrying the deletion of the qa-y gene support earlier evidence that this gene encodes a quinic acid permease. The strain containing the deletion of the qa...
