  1. 21. Contention-based Multiple Access Architectures for Networked Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Dawn Tilbury; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : Networked Control Systems (NCSs) use a wireless network for communication between sensors and controllers, and require a Medium Access Controller (MAC) to arbitrate access to the shared medium. Traditionally, a MAC for control systems is chosen primarily based on the delay it introduces in the closed loop. LÄS MER

  3. 22. What colour is the red house? Perceived colour of painted facades

    Författare :Karin Fridell Anter; KTH; []
    Nyckelord :Colour; architecture; perception; facade; exterior;

    Sammanfattning : Architects and others choosingfacade colours using colour samples face difficulties whichprevious research has not addressed. This work aims to aid suchcolour design by exploring three main questions: 1. LÄS MER

  4. 23. Study of neurodegenerative diseases with novel MRI techniques

    Författare :Xiaozhen Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurodegenerative diseases are a heterogeneous group of disorders that are characterized by the progressive degeneration of structure and function of the nervous system. They include diseases such as Alzheimer’s disease (AD), multiple sclerosis (MS) and others. LÄS MER

  5. 24. Radioimmunodiagnosis of Head and Neck Squamous Cell Carcinomas : Preclinical Studies

    Författare :Karl Sandström; Matti Anniko; Marika Nestor; Hans Lundqvist; Göran Laurell; Uppsala universitet; []
    Nyckelord :Head and neck squamos cell carcinoma; radioimmunotargeting; radioimmunodiagnosis; MEDICINE; MEDICIN;

    Sammanfattning : Despite improvements in treatment, the prognosis for patients with advanced head and neck squamous cell carcinomas (HNSCC) has only improved to a minor degree. To raise the success rate and minimize morbidity further developments in diagnostics are highly desired. Radioimmunodiagnosis could offer a more specific and sensitive diagnostic method. LÄS MER

  7. 25. Breaking the symmetry: creation and transfer of optical activity via total spontaneous resolution and stereoselective reactions

    Författare :Susanne Olsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective reactions; chirality; spontaneous resolution; conglomerate; organometallic chemistry; coordination compounds; attritionenhanced deracemisation; polymorphism; organolithium compounds; single-crystal X-ray crystallography;

    Sammanfattning : The generation of optical activity from achiral or racemic precursors – absolute asymmetric synthesis – is discussed in relation to the origin of biomolecular homochirality but is also often (incorrectly) regarded as being impossible. One approach to absolute asymmetric synthesis is the use of compounds that form chiral crystals. LÄS MER
