  1. 1. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

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

    Author : Oskar Darselius Berg; [2020]
    Keywords : Technology and Engineering;

    Abstract : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. READ MORE

  3. 2. Condition monitoring of induction machines using a signal injection technique

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sathiya Lingam Senthil Kumar; [2020]
    Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE

  4. 3. Detection of Sparse and Weak Effects in High-Dimensional Supervised Learning Problems, Applied to Human Microbiome Data

    University essay from KTH/Matematisk statistik

    Author : Fred Lindahl; [2020]
    Keywords : Signal detection; signal identification; higher criticism; microbiome data; sparse and weak effects; goodness-of-fit tests; kolmogorov-smirnov tests; Signal detektering; signal identifiering; higher criticism; mikrobiom data; glesa och svaga effekter; goodness-of-fit tester; Kolmogorov-smirnov tester;

    Abstract : This project studies the signal detection and identification problem in high-dimensional noisy data and the possibility of using it on microbiome data. An extensive simulation study was performed on generated data using as well as a microbiome dataset collected on patients with Parkinson's disease, using Donoho and Jin's Higher criticism, Jager and Wellner's phi-divergence-based goodness-of-fit-test and Stepanova and Pavlenko's CsCsHM statistic .

  5. 4. Possible unexpected peaks from oil drop size measurements in milk

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Laura Schalkwijk; Rodrigo Olmedo Sotomayor; [2020]
    Keywords : laser diffraction; oil droplet size; milk; pasteurised milk; unexpected peaks; mastersizer; food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : The shelf life of milk is amongst others dependent on the size of the oil droplets. These droplets can be measured using the laser diffraction (LD) technique. LD is a popular technique to measure particle size distributions (PSD) that has an outstanding broad measuring range capability, is easy-to-use and has a high reproducibility. READ MORE

  6. 5. Realistic Modelling of Ultrasound Sensing for Autonomous Vehicles

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Houbo Ni; [2019]
    Keywords : Ultrasonic sensor; analog signal; experimental setups; measurement methods; impedance; MATLAB;

    Abstract : Ultrasonic sensors are popular in parking functions in automotive. They are used to measure distances between a car and obstacles near the car. Car companies need to prove that sensors are reliable before using them on vehicles since these sensors are safety-critical. READ MORE
