  1. 1. The relation between rolling resistance and tyre temperature in real driving scenarios

    University essay from Linköpings universitet/Fordonssystem

    Author : Hugo Jansson; Martin Åsenius; [2021]
    Keywords : tyre; tire; model; temperature; brush model;

    Abstract : A large portion of the world’s total emissions is caused by the transport sector where rolling resistance is one of the contributing factors. The inner tyre temperature is a factor that greatly influences the rolling resistance. READ MORE

  3. 2. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Ahnesjö; [2020]
    Keywords : Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Abstract : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  4. 3. ALIGN, A sustainable cleaning tool for model makers

    University essay from Lunds universitet/Industridesign

    Author : Junjie Gu; [2020]
    Keywords : Cleaning tool; sustainability; home workspace; model making; Technology and Engineering; Arts and Architecture;

    Abstract : People who make models as their hobbies at home often generate more trash clutters than others. Once they start the modeling process, they often end up having small debris, sanding dust, and spilled paints on their desks. These tiny clutters will reduce their concentration and enthusiasm for the model-building process. READ MORE

  5. 4. Humpback whale (Megaptera novaeangliae) location in Southeast Alaska : modeling the influence of mesoscale krill (Euphausiacea) patch depth and size

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christine Walder; [2018]
    Keywords : physical geography and ecosystem analysis; humpback whales; krill; patchiness; vertical distribution; Generalized Additive Models GAMs ; spatial modeling; Earth and Environmental Sciences;

    Abstract : Humpback whales ([i]Megaptera novaeangliae[/i]) require dense prey aggregations due to the high energetic cost of their feeding methods. Modeling studies have shown that when whales are on their feeding grounds, they are closely associated with high prey concentrations. READ MORE

  6. 5. Limiting Spectral Distribution and Capacity of MIMO Systems

    University essay from Linköpings universitet/Matematiska institutionen; Linköpings universitet/Tekniska fakulteten

    Author : Simon Jönsson; [2017]
    Keywords : Random Matrices; Statistical Theory; MIMO systems; Wigner Matrices; Wishart Matrices; Spectral Distribution; Channel Capacity;

    Abstract : In this thesis we will brush through fundamental multivariate statistical theory and then present MIMO-systems briefly in order to later calculate the channel capacity of a MIMO system. After theory has been presented we will then look at different properties of the channel capacity and then investigate a supposed MIMO system dataset and use standardized methods to verify it’s model.
