  1. 1. Clutter Detection in Radar Applications

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Pedram Kasebzadeh; [2020]
    Keywords : ;

    Abstract : Radars have been used for detection purposes in safety applications (i.e., blind spot detection radar in cars) extensively. The existing detection methods, however, are not flawless. READ MORE

  2. 2. Analysis of an Ill-posed Problem of Estimating the Trend Derivative Using Maximum Likelihood Estimation and the Cramér-Rao Lower Bound

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Muhammad Farhan Naeem; [2020]
    Keywords : carbon dioxide levels; Keeling Curve; Taylor and Fourier series; Maximum Likelihood Estimation; MLE; Cramér-Rao Lower Bound; CRLB;

    Abstract : The amount of carbon dioxide in the Earth’s atmosphere has significantly increased in the last few decades as compared to the last 80,000 years approximately. The increase in carbon dioxide levels are affecting the temperature and therefore need to be understood better. READ MORE

  3. 3. On the Properties of Wiener-Lévy Functions

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Albin Petersson; [2019]
    Keywords : ;

    Abstract : This thesis concerns the Wiener algebra of periodic functions with absolutely convergent Fourier series, and the "Wiener-Lévy functions", meaning functions that preserve absolute convergence of Fourier series under composition. Results regarding the properties of functions in the Wiener algebra are established, as well as properties of Wiener-Lévy functions. READ MORE

  4. 4. Detecting exoplanets with machine learning : A comparative study between convolutional neural networks and support vector machines

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Jacob Tiensuu; Maja Linderholm; Sofia Dreborg; Fredrik Örn; [2019]
    Keywords : Machine learning; Exoplanet; Support vector machine; Convolution neuralnetwork;

    Abstract : In this project two machine learning methods, Support Vector Machine, SVM, and Convolutional Neural Network, CNN, are studied to determine which method performs best on a labeled data set containing time series of light intensity from extrasolar stars. The main difficulty is that in the data set there are a lot more non exoplanet stars than there are stars with orbiting exoplanets. READ MORE

  5. 5. Development of a method that quantifies the filtration efficiency of soft particles in drop-in fuels

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Swarga Shriharsha; [2019]
    Keywords : ;

    Abstract : The global carbon footprint is increasing with course of time. World is moving towards fossil free and reduce the dependency of fossil fuels to meet their daily needs. Transportation industry is the major user of fossil fuels today and major contributor to the CO2 emissions which leads to global warming. READ MORE
