  2. 1. 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.

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

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

    Abstract : 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. READ MORE
