    Sammanfattning : Enligt Socialstyrelsen år 2019 var hjärt-och kärlsjukdomar den vanligaste dödsanledningen i Sverige och svarade för 31 % av alla dödsfall i landet. Akut kranskärlssjukdom tillhör hjärt- och kärlsjukdomar och är en folksjukdom som drabbar både kvinnor och män i hela västvärlden med högst mortalitet till följd. LÄS MER

  3. 2. Reversing the flow of heat in system of initially correlated qubits

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
    Nyckelord :Qubits; Cooling; Heat Flow; Physics and Astronomy;

    Sammanfattning : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. LÄS MER

  4. 3. The Development of a New High Aspect-Ratio Turbulent Channel Flow Facility

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Agastya Parikh; [2020]
    Nyckelord :;

    Sammanfattning : Turbulent channel flows are of great interest for investigations of modified wall boundary conditions due to their well-understood characteristics and their broad applicability. In a reversal of typical trends, they can often be more difficult to investigate experimentally than to simulate owing to the far-reaching influence of corner effects as well as the need for development lengths in excess of 200 channel half-heights in order to produce high-quality flow.

  5. 4. BUILDING AND SIMULATING DYNAMIC MODELS OF DISTRICT HEATING NETWORKS WITH MODELICA : Using Matlab to process data and automate modelling and simulation

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Cristoffer Kos; Kristoffer Hermansson; [2017]
    Nyckelord :Heat losses; flow reversal; heat propagation; visualization; CAD; components; object-oriented; bi-directional; Värmeförluster; reversibelt flöde; värmeutbredning; visualisering; komponenter; objekt-orienterat; riktningsoberoende;

    Sammanfattning : District heating systems are common in Nordic countries today and accounts for a great portion of the heat demand. In Sweden, total district heating end use in the last years has been around 50 TWh and district heating accounts for roughly 50 % of the total heat demand. LÄS MER

  7. 5. Fund Flow Risk and Cross-Sectional Asset Prices

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Ludwig Bergenstråhle; Johannes Nordqvist; [2015]
    Nyckelord :Asset pricing; Mutual fund flows; Price pressure; Institutional trading;

    Sammanfattning : This paper documents that stocks whose historical excess returns have comoved more with mutual fund flows-have a higher fund flow beta (FFB)-earn higher future excess returns than otherwise similar stocks. We propose two hypotheses to explain this finding: First, funds may hedge the variance in their AUM by underweighing stocks with a high FFB, hence reducing the price of those stocks in equilibrium.
