  1. 1. On Aortic Blood Flow Simulations : Scale-Resolved Image-Based CFD

    Författare :Jonas Lantz; Matts Karlsson; Shawn Shadden; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on modeling and simulation of the blood flow in the aorta, the largest artery in the human body. It is an accepted fact that abnormal biological and mechanical interactions between the blood flow and the vessel wall are involved in the genesis and progression of cardiovascular diseases. LÄS MER

  3. 2. Turbulence Descriptors in Arterial Flows : Patient-Specific Computational Hemodynamics

    Författare :Magnus Andersson; Matts Karlsson; Jonas Lantz; Tino Ebbers; Kristian Valen-Sendstad; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : At this very moment, there are literally millions of people who suffer from various types of cardiovascular diseases (CVDs), many of whom will experience reduced quality of life or premature lift expectancy. The detailed underlying pathogenic processes behind many of these disorders are not well understood, but were abnormal dynamics of the blood flow (hemodynamics) are believed to play an important role, especially atypical flow-mediated frictional forces on the intraluminal wall (i.

  4. 3. Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI

    Författare :Belén Casas Garcia; Tino Ebbers; Jonas Lantz; Petter Dyverfeldt; Carljohan Carlhäll; Frans van de Vosse; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D Flow MRI; Computational modelling; Blood flow; Hemodynamics;

    Sammanfattning : Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease.

  5. 4. The role of biogas in a more sustainable energy system in Sweden

    Författare :Sofia Dahlgren; Stefan Anderberg; Thomas Magnusson; Jonas Ammenberg; Mikael Lantz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; CBG; LBG; Energy users; Sustainable transitions; Sustainability assessments;

    Sammanfattning : There are numerous problems in the world that need to be dealt with in order to achieve sustainable development. The energy system has significant negative impacts on many of these problems, and there is a need for a transition towards more sustainable energy. LÄS MER

  7. 5. Conditions for resource-efficient production of biofuels for transport in Sweden

    Författare :Carolina Ersson; Mats Eklund; Jonas Ammenberg; Mikael Lantz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. LÄS MER
