  1. 1. The Effects of Parallelizing Builds in Continuous Integration Software

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik; Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :William Lindblom; Jesper Johnsson; [2018]
    Nyckelord :Continuous Integration; CI; Parallel; Docker;

    Sammanfattning : Quick feedback in regards to build times is important in Continuous Integration. If builds become too long, it can hurt the rate of software development. There are multiple methods to reduce build times. One commonly suggested method is to parallelize builds. LÄS MER

  2. 2. Finite Element Approximations of 2D Incompressible Navier-Stokes Equations Using Residual Viscosity

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :William Sjösten; Victor Vadling; [2018]
    Nyckelord :Finite element method; incompressible Navier-Stokes equations; residual based artificial viscosity; stabilization; adaptive method; Chorin s method; IPCS; Crank-Nicholson s method; benchmark problems; CPU-time; accuracy;

    Sammanfattning : Chorin’s method, Incremental Pressure Correction Scheme (IPCS) and Crank-Nicolson’s method (CN) are three numerical methods that were investigated in this study. These methods were here used for solving the incompressible Navier-Stokes equations, which describe the motion of an incompressible fluid, in three different benchmark problems. LÄS MER

  3. 3. Software Benchmark and Material Selection in an Exhaust Manifold : Thermo-mechanical fatigue simulation of an exhaust manifold in AVL Fire M

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Oskar Rombo; [2018]
    Nyckelord :thermomechanical fatigue; TMF; simulation; viscoplastic;

    Sammanfattning : Today, there is a great focus on downsizing the engines, this means that the engines are made smaller in size but retain the same power. This in combination with the drive to increase the power of the engines has led to the engine components being exposed to high thermal loads. Today’s engines also use very high cylinder pressure.

  4. 4. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Maciej Maczugowski; [2017]
    Nyckelord :Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

    Sammanfattning : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. LÄS MER

  5. 5. Data acquisition system for optical frequency comb spectroscopy

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Ragnar Seton; [2017]
    Nyckelord :DAQS; HITRAN; MATLAB; libmx; Fourier Transform Spectrometry; Real time data visualization;

    Sammanfattning : The Optical Frequency Comb Spectroscopy (OFCS) Group at the Department of Physics at Umeå University develops new techniques for extremely high sensitivity trace gas detection, non invasive temperature measurements, and other applications of OFCS. Their setup used primarily for trace gas detection contains several components that have been developed in-house, including a Fourier Transform Spectrometer (FTS) and an auto-balancing detector.
