  1. 26. Design and evaluation of a battery power supply for a mobile XRF measurement system

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Xingyu Zhu; [2019]
    Keywords : XRF; Power; Battery; Boost-circuit; Buck-circuit; Voltage regulator;

    Abstract : X-ray fluorescence is a fast, non-destructive method to measure substances. This method can be used to detect elements in an environmental sample for elemental analysis. Commercially available XRF units exists, but their scope of application is limited. In the university lab, a more generalized XRF setup is available. READ MORE

  3. 27. Arrival Time Predictions for Buses using Recurrent Neural Networks

    University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Author : Christoffer Fors Johansson; [2019]
    Keywords : Machine Learning; Recurrent Neural Networks; RNN; Long short-term memory; LSTM; Regression; GTFS;

    Abstract : In this thesis, two different types of bus passengers are identified. These two types, namely current passengers and passengers-to-be have different needs in terms of arrival time predictions. A set of machine learning models based on recurrent neural networks and long short-term memory units were developed to meet these needs. READ MORE

  4. 28. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Maitane Muñoz Basagoiti; [2019]
    Keywords : quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Abstract : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.

  5. 29. Petrophysic of the Host-rock to the Ore in the Lovisa Mine, Bergslagen

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oscar Gilljam Päärt; [2019]
    Keywords : Petrophysics; density; magnetic volume susceptibility; natural remanent magnetization; Bergslagen; lithology; Petrofysik; densitet; magnetisk susceptibilitet; naturlig magnetisk remanens; Bergslagen; lithologi;

    Abstract : The Bergslagen region has three base-metal mines operating today, and one of them is the Lovisa mine, which host a Zn-Pb-Ag deposit. The Lovisa mine is located in the Guldsmedshyttan area north of Lindesberg. READ MORE

  6. 30. Online capacity estimation of Li-ion batteries with Errors-In-Variables model

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

    Author : Nikolaos Karavalakis; [2019]
    Keywords : ;

    Abstract : Sustainable transport has lead to recent technological advancements forelectric vehicles. A weak component of the electric vehicles is the energystorage units and their efficient operation. A battery management systemis usually employed to ensure the safe and efficient operation of the batteries. READ MORE
