  1. 1. How to Reduce Geometrical Variation in Assembled Products

    Författare :Johan S Carlson; Johan Carlson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; assembled products; body-in-white BIW ; dimensional variation; geometrical variation; fixtures; fixture diagnosis; locating schemes; multivariate analysis; rigid body motion; robust design; root cause; quality; root cause;

    Sammanfattning : Vehicle problems, such as wind noise, water leakage and door closing effort are examples of quality and functionality defects that are controlled by the dimensional accuracy of the structural frame of an auto body. The aim of this thesis is towards methods for reducing geometrical variation in assembled products in the automotiv other industries. LÄS MER

  2. 2. Variation Control in Virtual Product Realization - A Statistical Approach

    Författare :Kristina Wärmefjord; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

    Sammanfattning : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. LÄS MER

  3. 3. Radiographic follow-up analysis of Br?nemark? dental implants

    Författare :Solweig Sundén Pikner; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

    Sammanfattning : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. LÄS MER
