  1. 1. Spectral modeling of nebular-phase supernovae

    Författare :Anders Jerkstrand; Claes Fransson; Luc Dessart; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; nucleosynthesis; radiative transfer; massive stars; 1987A; IIP; supernovor; nukleosyntes; spektralmodellering; strålningstransport; massiva stjärnor; 1987A; IIP; Astronomy; astronomi;

    Sammanfattning : Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). LÄS MER

  3. 2. On Manufacturing System Development in the Context of Concurrent Engineering

    Författare :Dario Aganovic; KTH; []
    Nyckelord :Concurrent Engineering; Engineering Design; Development Methods and Tools; Manufacturing System; Information Management;

    Sammanfattning : This thesis presents an extension of the contemporaryengineering design theory towards a unified view onsimultaneous development of products and manufacturing systems,i.e. concurrent engineering. LÄS MER

  4. 3. Toward a Sustainable Human-Robot Collaborative Production Environment

    Författare :Abdullah Alhusin Alkhdur; Lihui Wang; Gunnar Bolmsjö; KTH; []
    Nyckelord :vision sensor; 3D image processing; collision detection; safety; robot; kinematics; dynamics; collaborative assembly; energy consumption; optimisation; manufacturing; Production Engineering; Industriell produktion;

    Sammanfattning : This PhD study aimed to address the sustainability issues of the robotic systems from the environmental and social aspects. During the research, three approaches were developed: the first one an online programming-free model-driven system that utilises web-based distributed human-robot collaboration architecture to perform distant assembly operations.
