  1. 1. Ocean Waves Estimation : An Artificial Intelligence Approach

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Andreas Ramberg; [2017]
    Keywords : Artificial Intelligence; Case-Based Reasoning; Encounter Angle; Encounter Spectrum; Feedforward Neural Network; Genetic Algorithm; Inverse Problem; Marine Vessels; Master Thesis; MATLAB; Model Parameter Estimation; Ocean Theory; Peak Period; Response Amplitude Operator; Ships; Significant Wave Height; Transfer Function; Wave Spectrum; Waves;

    Abstract : This thesis aims to solve the mathematical inverse problem of characterizing sea waves based on the responses obtained from a marine vessel sailing under certain sea conditions. By researching this problem the thesis contributes to the marine industry by improving products that are using ocean behavior for controlling ship's dynamics. READ MORE

  2. 2. Solving inverse problems in thermal engineering using a surrogate model

    University essay from KTH/Optimeringslära och systemteori

    Author : Sarra Fakhfakh; [2017]
    Keywords : ;

    Abstract : Through either measured or computed experimental data, inverse problems aim to determine parameters not straightforwardly given by measure. An inverse problem results in an optimization problem that requires many simulations of the direct problem which computations can be costly. One approach is to replace the reference model by a reduced model. READ MORE

  3. 3. Inverse correlation between freeze-thaw survival and storage stability of freeze-dried Lactobacillus reuteri DSM 17938 and a microcalorimetric search for GASP

    University essay from SLU/Department of Molecular Sciences

    Author : Radoslaw Sawicki; [2017]
    Keywords : freeze-drying; lyophilization; Lactobacillus reuteri; probiotic; pH; temperature; freeze-thaw; storage stability; survival; morphology; microscopy; long-term stationary phase; GASP; isothermal microcalorimetry;

    Abstract : Lactobacillus reuteri DSM 17938 is a probiotic bacterium manufactured by the company BioGaia AB and was in focus of this study. If a probiotic product is to confer its benefi-cial health effect to a consumer, it must retain high viability levels during long-term storage. READ MORE

  4. 4. Titanium vacancy diffusion in TiN via non-equilibrium ab initio molecular dynamics

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Davide Gambino; [2016]
    Keywords : Titanium nitride; Ti monovacancy migration; Non-equilibrium ab initio molecular dynamics; Color diffusion algorithm; Statistics for stochastic events;

    Abstract : Transition metal nitrides (TMNs) refractory ceramic materials are  widely employed as wear-resistant protective coatings in industrial machining as well as diffusion barriers inhibiting migration of metal impurities from the interconnects to the semiconducting region of electronic devices. TiN is the prototype of this class of materials and the most studied among TMNs. READ MORE

  5. 5. Diffuse Reflectance Spectroscopy: Using a Monte Carlo method to determine chromophore compositions of tissue

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Lisa Kobayashi Frisk; [2016]
    Keywords : Photonics; Biophotonics; Diffuse Reflectance; Spectroscopy; Monte Carlo; Diffusion; Physics and Astronomy;

    Abstract : In this work, inverse diffusion equation and Monte Carlo methods are used in conjunction with diffuse reflectance spectroscopy to develop a protocol for evaluating the chromophore compositions of tissue mimicking liquid phantoms. A novel two spectrometer system is used which provides real time calibration of any intensity fluctuations of the light source. READ MORE
