  2. 21. Novel measure of olfactory bulb function in health and disease

    Author : Behzad Iravani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Present neuroimaging techniques are capable of recording the neural activity from all over the brain but the olfactory bulb (OB). The OB is the first olfactory processing stage of the central nervous system and the site of insult in several neurological disorders, particularly Parkinson’s disease (PD). READ MORE

  4. 22. Hydraulic Power Steering System Design in Road Vehicles : Analysis, Testing and Enhanced Functionality

    Author : Marcus Rösth; Jan-Ove Palmberg; Nick Vaughan; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Power Steering; Active Safety; Comfort function; Shuttering; Linear modelling; Fluid mechanics; Strömningsmekanik;

    Abstract : Demands for including more functions such as haptic guiding in power steering systems in road vehicles have increased with requirements on new active safety and comfort systems. Active safety systems, which have been proven to have a positive effect on overall vehicle safety, refer to systems that give the driver assistance in more and less critical situations to avoid accidents.

  5. 23. Vintage models of spatial structural change

    Author : Lars Westin; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adiabatic approximation; dynamics; input-output; interregional computable general equilibrium; slaving principle; spatial models; spatial linear expenditure system; spatial price equilibrium; transportation networks; vintage function;

    Abstract : In the study a class of multisector network models, suitable for simulation of the interaction between production, demand, trade, and infrastructure, is presented. A characteristic feature of the class is a vintage model of the production system. READ MORE

  6. 24. Modeling and Control of VSC-HVDC Transmissions

    Author : Hector Latorre; Mehrdad Ghandhari; Luis Rouco; KTH; []
    Keywords : Control Lyapunov Functions; Energy Function; Modal Analysis; Transient Stability; Voltage Stability; VSC-HVDC Transmission.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Presently power systems are being operated under high stress level conditions unforeseen at the moment they were designed. These operating conditions have negatively impacted reliability, controllability and security margins. FACTS devices and HVDC transmissions have emerged as solutions to help power systems to increase the stability margins. READ MORE

  7. 25. Extremal eigenvalues and geometry of quantum graphs

    Author : Andrea Serio; Pavel Kurasov; Annemarie Luger; Evans Harrell; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum graphs; spectral estimates; trace formula; Euler characteristic; Mathematics; matematik;

    Abstract : This thesis consists of four papers concerning topics in the spectral theory of quantum graphs, which are differential operators on metric graphs.In paper I we present a family of graphs with an arbitrary number of cycles for which a certain eigenvalue upper estimate is sharp.
