  1. 1. Diagnostisk användbarhet av vaginalcytologi hos tik

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Sara Huber; [2023]
    Nyckelord :estradiol; vaginalcytologi; östruscykel; pyometra; juvertumör; tik;

    Sammanfattning : Syftet med detta arbete var att jämföra östradiolkoncentrationer och östradiolpåverkan på vaginal-epitelet hos tikar i olika löpstadier och tikar med sjukdomstillstånden pyometra och juvertumörer, och på så sätt studera användbarheten av vaginalcytologi som diagnostiskt verktyg vid dessa sjukdomstillstånd. Syftet var även att jämföra två olika metoder för att utvärdera vaginalutstryk. LÄS MER

  3. 2. The effect of autocorrelation when performing theapproximated permutation test

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Amerik Schouten; Linus Thor; [2023]
    Nyckelord :exchangeability assumption; Monte Carlo; temporal autocorrelation; type I error; simulation; re-sampling methods;

    Sammanfattning : In meteorology, permutation tests are a commonly recommended tool because standard paramet-ric methods of inference often is insufficient when analysing weather. Therefore other methodswith less stringent assumptions like permutation testing is used. LÄS MER

  4. 3. Subject-Verb Agreement Errors in Swedish 9th and 11th Grade Students’ English Written Production

    M1-uppsats, Högskolan i Gävle/Avdelningen för humaniora

    Författare :Maiko Tsukanaka; [2023]
    Nyckelord :Second Language Acquisition SLA ; Swedish Learner English Corpus SLEC ; Swedish-speaking learners of English; Error analysis; Subject-verb agreement; Transfer; Overgeneralization;

    Sammanfattning : This study aims to investigate possible factors contributing to subject-verb agreement errors in Swedish junior and senior high school students' English written production. The sample data is collected from the Swedish Learner English Corpus (SLEC), which comprises student texts produced in a classroom setting. LÄS MER

  5. 4. Ranging Error Correction in a Narrowband, Sub-GHz, RF Localization System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Silvia Barrett; [2023]
    Nyckelord :Localization; Narrowband; Sub-GHz; Radio Frequency; RSSI; Time-of-Flight; Error mitigation; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression; Loalisering; Narrowband; Sub-GHz; Radiofrekvens; RSSI; Time-of-Flight; Felkorrigering; Machine Learning; Linear Regression; LeastSquares Support Vector Machine Regression; Gaussian Process Regression;

    Sammanfattning : Being able to keep track of ones assets is a very useful thing, from avoiding losing ones keys or phone to being able to find the needed equipment in a busy hospital or on a construction site. The area of localization is actively evolving to find the best ways to accurately track objects and devices in an energy efficient manner, at any range, and in any type of environment. LÄS MER

  7. 5. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER
