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

    Författare :Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Source analysis of multiplet earthquakes (two case studies in Iran)

    Författare :Samar Amini; Roland Roberts; Björn Lund; Zaher Hossein Shomali; Kuvvet Atakan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiplet earthquakes; slip inversion; Coulomb stress; rupture directivity;

    Sammanfattning : Multiplet earthquakes are large earthquakes of similar magnitude which occur close in time in the same limited geographical area. They are not common but they considerably increase the potential hazard in the area in which they occur. LÄS MER

  4. 3. ”Det här är ju dött tåg liksom…” : en studie av metaforer för ROMANTISK KÄRLEK i talad svenska

    Författare :Per Boström; Ann-Catrine Edlund; Marlene Johansson Falck; Ekberg Lena; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Metaphor; ROMANTIC LOVE; Spoken Swedish; Metaphor identification; Discourse dynamic metaphor research; Conceptual metaphor; Cognitive Linguistics; Cultural model; Focus group research; language studies; språkvetenskap;

    Sammanfattning : The purpose of this study is to investigate the metaphorization of ROMANTIC LOVE in spoken Swedish. The study is based on 4 semi-structured focus group conversations with participants in two age groups; 24–33 and 50–54. A Swedish short film and questions related to the film were used as stimuli for the conversations. LÄS MER

  5. 4. Identification of Influential Factors on Android Smartphone-Based Video Quality of Experience

    Författare :Selim Ickin; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mobile handheld devices have become friends in people’s daily lives. Frequent usage of available applications, especially video streaming, causes exponential growth in mobile IP traffic. LÄS MER

  7. 5. Present and future precipitation variations in the source region of the Yangtze River, China

    Författare :Yiheng Du; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Precipitation; water balance; ENSO; PDO; Yangtze River; Tibet Plateau; future projections;

    Sammanfattning : The source region of the Yangtze River (SRYR), the origin of the longest river in China, is an area with high-mountains and river ecotones that face considerable challenges under climate change. Precipitation is fundamental for sustainable ecosystems in this area and for the downstream water supplies. LÄS MER
