  1. 16. Configuration of Platform Architectures in Construction

    Författare :Patrik Jensen; Lars Hvam; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mass customization; Modularization; Platform architecture; Configuration; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Construction is often defined as a project-oriented industry that develops complex one-of-a-kind products using an engineer-to-order (ETO) design process. The technical solutions that are developed in specific projects often have integral product architectures that are difficult to re-use in continuous improvement processes. LÄS MER

  3. 17. Functional properties of galectin-3. Beyond the sugar binding

    Författare :Adriana Lepur; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galectin-3; galectin-1; M1 macrophage; M2 macrophage; self-association; fluorescence anisotropy; citrus pectin; galactomannane;

    Sammanfattning : Contemporary diseases like diabetes, asthma, atherosclerosis etc. are marked by chronic inflammation, often supported by the activity of different macrophages. Proteins from galectin family were found to contribute to disease pathophysiology. Therefore, there is an intensive interest in understanding different galectin functions. LÄS MER

    Sammanfattning : This work concerns the microstructure of YBa2Cu3O7-.delta. (YBCO) and other related thin films in multilayer structures, studied by mainly transmission electron microscopy (TEM). LÄS MER

  5. 19. Fabrication and Characterization of Nanocontact Spin-Torque Oscillators

    Författare :Sohrab Redjai Sani; Johan Åkerman; Brad Engel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spin-torque oscillators; phase locking; spin wave; giant magnetoresistance; spin transfer torque; thin films.;

    Sammanfattning : The manufacturing of nanocontact-based spin-torque oscillators (NC-STOs)has opened the door for spintronic devices to play a part as active microwaveelements. The NC-STO has the capability of converting a direct current intoa microwave signal, and vice versa, by utilizing the spin transfer torque (STT)in ferromagnetic multilayer systems. LÄS MER

  7. 20. Magnetization Dynamics in Nano-Contact Spin Torque Oscillators : Solitonic bullets and propagating spin waves

    Författare :Stefano Bonetti; Johan Åkerman; Thomas Silva; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; spintronics; thin magnetic films; spin transfer torque; magnetization dynamics; spin waves; microwave oscillators; giant magneto-resistance; Magnetism; Magnetism;

    Sammanfattning : Magnetization dynamics in nano-contact spin torque oscillators (STOs) is investigated from an experimental and theoretical point of view. The fundamentals of magnetization dynamics due to spin transfer torque are given. A custom-made high frequency (up to 46 GHz) in large magnetic fields (up to 2. LÄS MER
