2. 1. Improved Quality Assurance of Fatigue Loaded Structures - The Necessary Shift from Technology Focus towards Information Driven Weld Evaluation

   Author : Anna Öberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lean; fatigue; NDT; information; inspection; control; assurance; six sigma; quality; weld;

   Abstract : The research has shown that the insufficient use of process information leads to unnecessary and costly safety margins in each step of production. This is, in short term, affecting the productivity of the company. Even more serious is the effect that insufficient use of process information has on product and process development in the long term. READ MORE

4. 2. Weighted Analysis of Microarray Experiments

   Author : Anders Sjögren; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA microarray; differential expression; gene expression; quality control QC ; quality assurance QA ; quality assessment; generalised linear model; empirical Bayes; weighted moderated statistic; invalid p-value; heteroscedasticity; WAME; heteroscedasticity;

   Abstract : DNA microarrays are strikingly efficient tools for analysing gene expression for large sets of genes simultaneously. The aim is often to identify genes which are differentially expressed between some studied conditions, thereby gaining insight into which cellular mechanisms are differently active between the conditions.

5. 3. Internal Control : A Study of the Concept and Themes of Internal Control

   Author : Olof Arwinge; Fredrik Nilsson; Nils-Göran Olve; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP; Economic Information Systems; Ekonomiska informationssystem;

   Abstract : This thesis studies the accounting and auditing approach to control where the concept of internal control has developed along with the theory and practice of accounting and auditing and its stated objectives. In this context, internal control has traditionally been regarded as a means of ensuring financial reporting quality as well as a way of preventing and detecting fraudulent activity. READ MORE

6. 4. Colorectal Cancer : Audit and Health Economy in Colorectal Cancer Surgery in a Defined Swedish Population

   Author : Pia Jestin; Ulf Gunnarsson; Lars Påhlman; Bengt Glimelius; Jörgen Rutegård; Uppsala universitet; []

   Abstract : Colorectal cancer is one of the most common malignancies in Sweden, with more than 5000 new cases annually. Median age at time of diagnosis is approximately 75 years. Owing to the ageing population, the incidence of colorectal cancer is increasing. READ MORE

7. 5. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety

   Author : Fredrik Nordström; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; monitor unit verification; in vivo dosimetry; real-time verification; gel dosimetry; 4D dosimetry; IMRT; VMAT; data integrity; radiotherapy; Quality assurance;

   Abstract : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.
