1. 16. Normalization and Differential Gene Expression Analysis of Microarray Data

   Författare :Magnus Åstrand; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : DNA microarray technologies have the capability of simultaneously measuring the abundance of thousands of mRNA-sequences. Analysis of microarray data involves many different steps such as image analysis, background correction, and normalization, but also more classical statistical analysis such as testing for significant differences between groups of arrays.

3. 17. Requirements Prioritisation and Retrospective Analysis for Release Planning Process Improvement

   Författare :Lena Karlsson; Institutioner vid LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Empirical research; Process improvement; Retrospective analysis; Release planning; Requirements engineering; Software engineering; Data- och systemvetenskap; computer technology;

   Sammanfattning : The quality of a product can be defined by its ability to satisfy the needs and expectations of its customers. Achieving quality is especially difficult in market-driven situations since the product is released on an open market with numerous potential customers and users with various wishes. LÄS MER

4. 18. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

   Författare :Johan Setréus; Lina Bertling; Roland Eriksson; Stefan Arnborg; Lars Wredenberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; Electric power engineering; Elkraftteknik;

   Sammanfattning : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. LÄS MER

5. 19. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology

   Författare :Kostas Stylidis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; luxury; knowledge management; engineering; premium; design; engineering; automotive; product quality; ; product development; aesthetics; perceived quality;

   Sammanfattning : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.

7. 20. Thermal shock and thermal fatigue in ceramic materials

   Författare :Tomas Andersson; KTH; []
   Nyckelord :;

   Sammanfattning : This thesis concerns thermal stress fracture in ceramicmaterials. The work describes a new technique for determiningthe thermal shock resistance of brittle materials as well asexperimental results and thermal stress simulations. LÄS MER
