  1. 1. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jonas Fahlman; [2023]
    Keywords : astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Abstract : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

  3. 2. MmWave Radar-based Deep Learning Collision Prediction

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

    Author : Taylor Lauren V'dovec; [2023]
    Keywords : collision prediction; mmWave radar; deep learning; variational autoencoder VAE ; drone; autonomous navigation; kollisionsprognos; mmWave radar; djupinlärning; variational autoencoder VAE ; drönare; autonom navigation;

    Abstract : Autonomous drone navigation in classical approaches typically involves constructing a map representation and employing path planning and collision checking algorithms within that map. Recently, novel deep learning techniques combined with depth camera observations have emerged as alternative approaches capable of achieving comparable collision-free performance. READ MORE

  4. 3. Trädens växtplats i staden : jämförelse mellan två växtbäddsystem med fokus på konstruktion och tillväxt

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Johanna Pantulin Nordlund; [2023]
    Keywords : stadsträd; klimatanpassning; markförhållanden; strukturell jord; skelettjord; Stockholm; strukturella system; plastceller; växtceller; Milford;

    Abstract : Extrema väderförhållanden blir allt vanligare på grund av klimatförändringarna vilket leder till ökade risker för värmeböljor, skyfall och torka. Samtidigt växer världens städer och fler människor flyttar in till mer urbana miljöer. För att klara ett förändrat klimat behöver städerna anpassas. READ MORE

  5. 4. C/O+ charge transfer & the Olson-Demkov model

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Kristoffer Bengtsson; [2021]
    Keywords : Astronomy; Charge transfer; rate coefficient; Carbon; Oxygen; energy defect; spectral modelling; supernovae;

    Abstract : Charge transfer reactions and their rates play a key role in correctly estimating element abundances in astrophysical objects such as supernovae. The reaction $C + O^+ \rightarrow C^+ + O(^1D) + \Delta E$ has been shown to be of significance when estimating oxygen abundances through model spectrum evaluations, and the relative rate of this reaction can under certain circumstances completely dictate the neutralization rate of oxygen ions.

  6. 5. Monocular Visual Odometry for Autonomous Underwater Navigation : An analysis of learning-based monocular visual odometry approaches in underwater scenarios

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

    Author : Andrea Caraffa; [2021]
    Keywords : Deep Learning; Monocular Visual Odometry; Computer Vision; Autonomous Underwater Navigation; Autonomous Underwater Vehicle; Djupinlärning; Monokulär Visuell Odometri; Datorseende; Autonom Undervattensnavigering; Autonomt Undervattensfordon;

    Abstract : Visual Odometry (VO) is the process of estimating the relative motion of a vehicle by using solely image data gathered from the camera. In underwater environments, VO becomes extremely challenging but valuable since ordinary sensors for on-road localization are usually unpractical in these hostile environments. READ MORE
