  2. 1. Active Flow Control for Reducing Drag on Trucks: from Concept to Full Scale Testing

    Author : Guglielmo Minelli; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFC; Experiments; Vehicle Aerodynamics; Partially-Averaged Navier-Stokes; PANS; LES; Wind Tunnel; POD; Active Flow Control; Large Eddy Simulations; Proper Orthogonal Decomposition; PIV;

    Abstract : There is no doubt that road vehicle transportation is needed to improve efficiency, to reduce power consumption and to contribute to a sustainable mobility. Aerodynamics plays a crucial role in this, and its optimization can have a significant impact on fuel efficiency. READ MORE

  4. 2. Drag Reduction by means of Active Flow Control Applied on a Generic Truck A-pillar: a Numerical and Experimental Study

    Author : Guglielmo Minelli; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PANS; Large Eddy Simulation; Wind Tunnel.; Bluff Body Flow; Modal Decomposition; Experiments; Vehicle Aerodynamic; POD; Active Flow Control; LES; Partially Averaged Navier Stokes; AFC;

    Abstract : The overall goal of this thesis is to isolate and control the flow mechanism characterizing the flow separation occurring at the A-pillar of a truck. The study aims to gain knowledge of the flow physics of the separation mechanism, and to eventually suppress the afore mentioned separation by means of an Active Flow Control. READ MORE

  5. 3. Excitonic and charge carrier transport in organic materials and device applications

    Author : Qingzhen Bian; Olle Inganäs; Feng Gao; Ergang Wang; Guglielmo Lanzani; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With the potential for future commercial use, organic electronics have been intensively studied for the last few decades. To exploit the next generation of high-performance devices, detailed study of the underlying physics is essential. READ MORE

  6. 4. Asymmetry and multiscale dynamics in macroeconomic time series analysis

    Author : Olivier Habimana; Pär Sjölander; Kristofer Månsson; Guglielmo Maria Caporale; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of three independent articles preceded by an introductory chapter. The first two articles focus on exchange rate dynamics in emerging market and developing economies, taking into account nonlinearities and asymmetries which are relevant for these countries and are potentially due to (i) transaction costs and other market frictions, and (ii) official intervention in the foreign exchange market.

  7. 5. Market Models with Stochastic Volatility

    Author : Jean-Paul Murara; Sergei Silvestrov; Guglielmo D’Amico; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : Financial Markets is an interesting wide range area of research in Financial Engineering. In this thesis, which consists of an introduction, six papers and appendices, we deal with market models with stochastic volatility in order to understand some financial derivatives, mainly European options.
