  1. 1. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty

    Master-uppsats, KTH/Matematisk statistik

    Författare :Ricky Molén; [2023]
    Nyckelord :Phylogeny; Bayesian analysis; Markov chain Monte Carlo; Variational inference; Mixture of proposal distributions; Fylogeni; Bayesiansk analys; Markov Chain Monte Carlo; Variationsinferens; Mixturer av förslagsfördelningar;

    Sammanfattning : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

  3. 2. Do Stocks Outperform Treasury Bills? Evidence From a Swedish Setting

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Anton Li; Ricky Yu; [2023]
    Nyckelord :Individual stocks; Treasury bills; Skewness; Buy-and-hold returns; Diversification;

    Sammanfattning : Most Swedish stocks listed since 1983 post lifetime buy-and-hold returns that are less than one-month Swedish Treasury bills. In terms of risk-adjusted returns for the same time horizon, individual Swedish stocks vastly underperform value-weighted benchmarks when measured with a Sharpe ratio. LÄS MER

  4. 3. A Close Reading of Two Invisible Survival-Horror Characters: : A comparison between the Kaernk from Amnesia: The Dark Descent and the Walrider from Outlast

    Kandidat-uppsats, Uppsala universitet/Institutionen för speldesign

    Författare :Ariana Morgana; Ricky Lilja; [2022]
    Nyckelord :character design; close-reading; enemy design; horror games; invisible enemy; survival horror; video games; Walrider; Outlast; Kaernk; Amnesia: The Dark Descent;

    Sammanfattning : This thesis looks at two invisible characters, the Kaernk from Amnesia: The Dark Descent and the Walrider from Outlast, to investigate how these characters are incorporated into and contribute to elements found within survival-horror games, and how their design affects the player. The thesis uses a close-reading methodology adapted for video-games to generate data used to first describe each of the characters and the scenario where they are first encountered, and later analyze and discuss the data, as well as compare the data from each character to one another.

  5. 4. The ghost in the machine : Exploring the impact of noise in datasets used for graph-based action recognition

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

    Författare :Ruben Rehn; Ricky Molén; [2021]
    Nyckelord :;

    Sammanfattning : Human action recognition is the task of classifying human movement and actions from video data. To benchmark different algorithms within the action recognition field, a common benchmark dataset, called NTU-RGB+D is used. However, this dataset is not without its issues as some samples contain data that is mistakenly captured as a human. LÄS MER

  7. 5. Control Strategies for Variable Air Volume Ventilation used as a Demand Response Resource

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Ricky Klasson; Johan Frykebrant; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The Swedish power grid is actively balanced in order to maintain the nominal frequency of 50 Hz. Today, this is mostly done through flexible power generation. Emerging markets, allowing consuming resources to participate in balancing the grid, have the potential to increase the stability of the grid. LÄS MER
