  1. 16. Convergence Rate of the Dirichlet-Neumann Algorithm for Coupled Poisson Equations

    University essay from Lunds universitet/Matematik LTH

    Author : Morgan Görtz; [2019]
    Keywords : Dirichlet-Neumann; Dirichlet-Neumann algorithm; Poisson equation; convergence rate; finite element method; finite volume method; finite difference method; Mathematics and Statistics;

    Abstract : This thesis presents and tests the convergence rate of the Dirichlet-Neumann algorithm for two Poisson equations coupled by transmission boundary conditions. Three second order discretisation methods are used when analyzing the convergence: standard equidistant finite difference, standard adaptive linear finite element, and standard adaptive finite volume discretisation of Poisson's equation.

  3. 17. Plan för inventering av miljöer och möjligheter ur ett hälsoperspektiv anpassad till gamla kulturmiljöer : belysande exempel från gården Grönhult i nordöstra Skåne

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Linn Borglund; [2019]
    Keywords : natur; förebyggande hälsa; kulturmiljöer; inventering; landsbygdsturism; Grönhult;

    Abstract : Vårt moderna liv medför många hälsorisker. Många människor mår både fysiskt och psykiskt dåligt, blir fjärmade från naturen, saknar känslor av platsanknytning och upplever att de saknar band till tidigare generationer. READ MORE

  4. 18. Exercise-induced cardiac remodeling : a potential cause of pathological changes in the equine heart?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Maria Neil; [2019]
    Keywords : Cardiac remodeling; equine; horse; exercise; hypoxia; valvular regurgitation; cardiac murmur; atrial fibrillation;

    Abstract : Cardiac remodeling is a response to exercise that has been reported in a number of different species. Intensified training will lead to an increasing demand on the cardiovascular capacity, because of the requirements of enhanced oxygen delivery, metabolism and thermoregulation. READ MORE

  5. 19. Flavour-ordering in the nonlinear sigma model with more derivatives and legs

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Mattias Sjö; [2019]
    Keywords : Particle physics; effective field theory; QCD; mesons; amplitudes; Physics and Astronomy;

    Abstract : We present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a power-counting hierarchy. READ MORE

  6. 20. Multimaterial 3D Printing of a mechanically representative aortic model for the testing of novel biomedical implants

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sudhanshu Kuthe; [2019]
    Keywords : 3D printing; Aortic model; Composite design; Stiffness; Bio-material;

    Abstract : Aortic stenosis is a serious cardiovascular disease that requires urgent attention and surgical intervention. If not treated, aortic stenosis can result in heart attack or cardiac arrest. Transcatheter Aortic Valve Replacement is a surgical technique that is used to treat aortic stenosis. READ MORE
