  1. 26. Evaluating Random Forest and k-Nearest Neighbour Algorithms on Real-Life Data Sets

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

    Author : Atheer Salim; Milad Farahani; [2023]
    Keywords : Random Forest; k-Nearest Neighbour; Evaluation; Machine Learning; Classification; Execution Time; Slumpmässig Skog; k-Närmaste Granne; Utvärdering; Maskininlärning; Klassificiering; Exekveringstid;

    Abstract : Computers can be used to classify various types of data, for example to filter email messages, detect computer viruses, detect diseases, etc. This thesis explores two classification algorithms, random forest and k-nearest neighbour, to understand how accurately and how quickly they classify data.

  3. 27. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Elias Aretorn; [2023]
    Keywords : CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

    Abstract : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. READ MORE

  4. 28. Expression Simplification Using E-Graphs for Interval Evaluation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Simon Björklund; [2023]
    Keywords : ;

    Abstract : Daisy is a framework for verifying and bounding the magnitudes of rounding errors introduced by floating-point arithmetic in numerical programs. As part of this, Daisy employs a rudimentary algorithm for simplifying expressions derived from the programs. READ MORE

  5. 29. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Jakob Brandt; [2023]
    Keywords : Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

    Abstract : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

  6. 30. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Renato Franze; [2023]
    Keywords : Attitude Dynamics; Attitude Control; Earth Observation; Scheduling; Attityddynamik; Attitydkontroll; Jordobservation; Uppgiftsschemaläggning;

    Abstract : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. READ MORE
