  1. 1. Key Technologies in Low-cost Integrated Vehicle Navigation Systems

    Författare :Yueming Zhao; Lars E. Sjöberg; Milan Horemuž; Hossein Nahavandchi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; INS; MEMS; error modelling; integration structure; lane detection; camera motion; balance adjustment; sensor array;

    Sammanfattning : Vehicle navigation systems incorporate on-board sensors/signal receivers and provide necessary positioning and guidance information for land, marine, airborne and space vehicles. Among different navigation solutions, the Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. LÄS MER

  3. 2. Integration and function of new neurons generated from fibroblasts and adult neural stem cells in the pathological brain

    Författare :James Wood; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurogenesis; neural stem cells; iNs; iPS cells; stroke; epilepsy; electrophysiology;

    Sammanfattning : In Papers One through Six we have investigated the function and integration of “new” neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. LÄS MER

  4. 3. The Ins and Outs of Membrane Proteins : Topology Studies of Bacterial Membrane Proteins

    Författare :Mikaela Rapp; Gunnar von Heijne; Christopher Tate; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane protein; topology; dual topology; Biochemistry; Biokemi;

    Sammanfattning : α-helical membrane proteins comprise about a quarter of all proteins in a cell and carry out a wide variety of essential cellular functions. This thesis is focused on topology analyses of bacterial membrane proteins. The topology describes the two-dimensional structural arrangement of a protein relative to the membrane. LÄS MER

  5. 4. GNSS-aided INS for land vehicle positioning and navigation

    Författare :Isaac Skog; Peter Händel; Bengt Boberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER

  7. 5. Enterostatin - target proteins and intracellular mechanisms. Function in food intake and energy metabolism

    Författare :Karin Berger; Molekylär endokrinologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; energy metabolism; insulin; uncoupling protein; beta-casomorphin; opiate; SK-N-MC; INS-1; Medicin människa och djur ; Medicine human and vertebrates ; fat intake; F1F0-ATP synthase; appetite; enterostatin; satiety; obesity;

    Sammanfattning : Hunger and satiety are the results of complex neural events that involve several neurotransmitters and peptides. Enterostatin is an appetite-regulating peptide released in the intestine in response to fat ingestion. Enterostatin specifically decreases fat intake, but has also metabolic effects like inhibition of insulin secretion. LÄS MER
