  2. 1. Functions of Generalized Bounded Variation

    Author : Martin Lind; Viktor Kolyada; Peter Oswald; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bounded p-variation; generalized bounded variation; modulus of continuity; function spaces; embeddings; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation.First, we study the functions of bounded p-variation introduced by Wiener in 1924. We obtain estimates of the total p-variation (1.. READ MORE

  4. 2. Part Quality Prediction and Variation Reduction in Multistage Machining Processes Based on Skin Model Shapes

    Author : Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; model-based prediction; variation propagation; variation source identification; variation compensation; tolerance analysis; Octree; anomaly detection; quaternion; dual quaternion; Plücker coordinate.; Maskinbearbetningssimulering; modellbaseradförutsägelse; variationsspridning; variationskällidentifiering; variationskompensation; toleransanalys; Octree; dual quaternions; Plücker-koordinat.; Production Engineering; Industriell produktion;

    Abstract : All manufacturing processes inevitably induce variations into manufactured parts that may result in nonconformance. Nonconforming parts incur costs due to the additional process required for rework or scrap loss. Hence, methodical efforts to reduce these variations are necessary for competitive manufacturing.

  5. 3. Managing Geometrical Variation through Optimization and Visualization

    Author : Johan Lööf; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation simulation; tolerancing; Tolerance allocation; locating scheme optimization; geometry assurance; visualization of variation; tolerance analysis;

    Abstract : All manufacturing processes are afflicted by variation that causes deviations in critical dimensions in the final product. Geometrical variation results in form and size deviation in individual parts. Assembly variation comes from defects in assembly equipment, and influence how parts are mounted together. READ MORE

  6. 4. Variation simulation of sheet metal assemblies for geometrical quality : parameter modeling and analysis

    Author : Stefan Dahlström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerancing; geometrical variation; variation simulation; sheet metal assembly; virtual verification; geometrical quality;

    Abstract : The automotive industry deals with an increased demand for virtual verification of the geometrical quality of the product. The aim is to reduce the need for adjusting the assembly process to deliver a product with high quality. READ MORE

  7. 5. Eliciting Knowledge from Experts in Modeling of Complex Systems : Managing Variation and Interactions

    Author : Per Wikberg; Bo Strangert; Erland Svensson; Berndt Brehmer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modeling; Experts; Communication; Qualitative Data; Roles; Cognitive science; Kognitionsvetenskap;

    Abstract : The thematic core of the thesis is about how to manage modeling procedures in real settings. The view taken in this thesis is that modeling is a heuristic tool to outline a problem, often conducted in a context of a larger development process. READ MORE
