  2. 1. Orsaker till fel i byggandet: en studie om felorsaker, felkonsekvenser, samt hinder för inlärning i byggprojekt

    Author : Per-Erik Josephson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; consequences of defects; causes of defects; organisational behaviour; organisational learning; building project; quality; temporary organisations; defects; costs of defects;

    Abstract : One means of increasing the effectiveness of building is minimisation of the numbers of de-fects and their consequences. In order to accomplish this, it is necessary to have knowledge of why defects occur, of their consequences, and of how to learn from errors. READ MORE

  4. 2. Evolution of artificial defects during shape rolling

    Author : Mirjana Filipovic; Stefan Jonsson; Per-Olov Perä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire rod rolling; artificial defects; defect evolution; surface cracks; porosity; FEM; high speed steel; stainless steel; Other materials science; Övrig teknisk materialvetenskap; Initiering och utveckling av defekter under spårvalsning;

    Abstract : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. READ MORE

  5. 3. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Abstract : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. READ MORE

  6. 4. Macro-Geometric Defects, A numerical and experimental study of springback and surface defects

    Author : Alf Andersson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation; Sheet-metal forming; Finite element analysis; Information exchange; Springback; Surface defects; Drawbead; Process analyse; Optimisation; materialteknik; Materiallära; Material technology;

    Abstract : Today, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods at every stage of the process development chain. In order to decrease the long lead-time for producing a forming tool, sheet-metal-forming simulation was introduced. READ MORE

  7. 5. Early and Cost-Effective Software Fault Detection : Measurement and Implementation in an Industrial Setting

    Author : Lars-Ola Damm; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software; faults; defects; early fault detection; software process improvement;

    Abstract : Avoidable rework consumes a large part of development projects, i.e. 20-80 percent depending on the maturity of the organization and the complexity of the products. High amounts of avoidable rework commonly occur when having many faults left to correct in late stages of a project. READ MORE
