  1. 16. Collective behaviour in suspensions of pushers and pullers

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Shan Anjum; [2019]
    Keywords : biophysics; active matter; collective motion; microswimmers; biohydrodynamics; non-equilibrium physics; low reynolds number physics; biophysical chemistry; biofysikalisk kemi; Physics and Astronomy; Chemistry; Technology and Engineering;

    Abstract : Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. READ MORE

    Abstract : Convolutional artificial neural networks can be applied for image-based object classification to inform automated actions, such as handling of objects on a production line. The present thesis describes theoretical background for creating a classifier and explores the effects of introducing a set of relatively recent techniques to an existing ensemble of classifiers in use for an industrial sorting system.

  4. 18. Numerical analysis of aerodynamic damping in a transonic compressor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vincenzo Stasolla; [2019]
    Keywords : transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

  5. 19. Influence of media on piezoelectric pressure transducers

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Atsuhide Inatomi; [2019]
    Keywords : ;

    Abstract : The influence of media on piezoelectric pressure transducers are studied experimentally, numerically and analytically. The transient pressure is measured in different types of media in order to discuss the possible effects. READ MORE

  6. 20. Artificial Groundwater Injection : A Study of Groundwater Level Control in Swedish Infrastructure Projects

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martin Kjellberg Skjenken; [2019]
    Keywords : Groundwater; Subsidence; Artificial Recharge; Artificial Groundwater injection; Climate Change; Numerical modelling; Infrastructure and Swedish Transport Administration; Grundvatten; marksättningar; Skyddsinfiltration; Framtida klimatförändringar; Infrastruktur; Numerisk modellering; Trafikverket;

    Abstract : This thesis sets out to increase the knowledge of artificial groundwater injection (AGWI) in Sweden on behalf of the Swedish Transport Administration. This has been done by firstly conducting a literature review which provided the background which comprises mainly groundwater theory and subsidence. READ MORE
