  3. 2. Decision Trees for Classification of Repeated Measurements

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Julianna Holmberg; [2024]
    Keywords : Repeated Measurement Data; Growth Curve Model; Linear Discriminant Analysis; Decision Tree; Bootstrap Aggregating; CART; CART-LC;

    Abstract : Classification of data from repeated measurements is useful in various disciplines, for example that of medicine. This thesis explores how classification trees (CART) can be used for classifying repeated measures data. READ MORE

  4. 3. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. READ MORE

  5. 4. Dare. Dream. Done. [Sparkles emoji] : Pragmatic functions and sentiment of emojis in tweets by American, English, Australian, Indian, and Nigerian users

    University essay from Karlstads universitet/Fakulteten för humaniora och samhällsvetenskap (from 2013)

    Author : Kristoffer Olsén; [2024]
    Keywords : ambiguity; computer-mediated communication; cyberpragmatics; emoji; emoji usage pattern; national variety; pragmatics; sentiment; tweets; användningsmönster för emojis; attityd; cyberpragmatik; datorförmedlad kommunikation; emoji; nationell variation; pragmatik; tvetydighet; tweets;

    Abstract : Emojis can be ambiguous, even when used within one and the same language and geographic region, but they are also a globally accessible language in computer-mediated communication. This paper aims to examine if emoji usage across five different national varieties of English (American, English, Australian, Indian, and Nigerian), geographically located on five different continents, exhibits similar pragmatic functionality and sentiment.

  6. 5. Robust Portfolio Optimization with Correlation Penalties

    University essay from KTH/Matematisk statistik

    Author : Pelle Nydahl; [2023]
    Keywords : Portfolio Optimization; Portfolio Allocation; Robust Optimization; Correlation; Risk Factor Model; EMA Filtering; Weighted Linear Regression; Portföljoptimering; Portföljallokering; Robust optimering; Korrelation; Riskfaktor-modell; EMA-filtrering; Viktad linjär regression;

    Abstract : Robust portfolio optimization models attempt to address the standard optimization method's high sensitivity to noise in the parameter estimates, by taking an investor's uncertainty about the estimates into account when finding an optimal portfolio. In this thesis, we study robust variations of an extension of the mean-variance problem, where an additional term penalizing the portfolio's correlation with an exogenous return sequence is included in the objective.
