  1. 1. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Alberta van Gent; [2023]
    Nyckelord :Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

    Sammanfattning : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.

  3. 2. Estimating Ambient Temperature using Internal Sensors and Thermal Modelling in Mobile Phones

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

    Författare :Isak Evaldsson; Henrik Paulcén; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals of specific devices.

  4. 3. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Reman Soryani; [2023]
    Nyckelord :Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER

  5. 4. Formula Student Car Stability

    Kandidat-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Oliver Belfiore; [2023]
    Nyckelord :Racing; Car; Vehicle; dynamics; vehicle dynamics; Technology and Engineering;

    Sammanfattning : This thesis investigates the impact of varying passive components on the stability of a Formula Student race car. The study was conducted using a 7-post model and a lateral model, both of which were derived using Lagrangian methods and state-space modelling techniques. These models were then validated and adjusted using logged data. LÄS MER

  7. 5. Machine Learning-Based Instruction Scheduling for a DSP Architecture Compiler : Instruction Scheduling using Deep Reinforcement Learning and Graph Convolutional Networks

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

    Författare :Lucas Alava Peña; [2023]
    Nyckelord :Instruction Scheduling; Deep reinforcement Learning; Compilers; Graph Convolutional Networks; Schemaläggning av instruktioner; Deep Reinforcement Learning; kompilatorer; grafkonvolutionella nätverk;

    Sammanfattning : Instruction Scheduling is a back-end compiler optimisation technique that can provide significant performance gains. It refers to ordering instructions in a particular order to reduce latency for processors with instruction-level parallelism. LÄS MER
