  1. 1. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi

    Författare :Simon Kreipl; [2021]
    Nyckelord :Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Sammanfattning : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. LÄS MER

  3. 2. Analysis of online news media through visualisation and text clustering

    Nyckelord :text categorisation; k-means clustering; visualisation; online news.;

    Sammanfattning : Online news has grown in frequency and popularity as a convenient source of information for several years. A result of this drastic surge is the increased competition for viewer-ship and prolonged relevance of online news websites. LÄS MER

  4. 3. Studies of pyridine in water clusters with synchrotron radiation and 3D momentum spectrometry

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Benjamin Bolling; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. LÄS MER

  5. 4. Företagskluster och närhet i Katutura, Namibia : En studie kring småföretag, närhet och klusterfördelar

    Kandidat-uppsats, Umeå universitet/Kulturgeografi

    Författare :Benjamin Amukena Nyqvist; [2015]
    Nyckelord :;

    Sammanfattning : In Economic Geography, there has been a strong interest of how different forms of proximity impacts businesses. In addition, there is also a strong interest in business agglomeration, as a result businesses cluster together through physical proximity, networks and knowledge. LÄS MER

  7. 5. Insider trading and abnormal return on the Swedish stock market

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Philip Ek; Karin Erlinder; [2015]
    Nyckelord :Insider trading; Abnormal Returns; Cluster formations; Event study; Swedish stock market; Business and Economics;

    Sammanfattning : Title: Insider trading and abnormal return on the Swedish stock market Seminar Date: 2015-05-25 Course: FEKN90 Examensarbete på civilekonomprogrammet (30hp) Authors: Philip Ek and Karin Erlinder Advisor: Rikard Larsson Purpose: By using classifications of different kinds of insiders we wish to en-lighten this area of study with empirical evidence of how insiders on the Swedish Stock Exchange yield abnormal returns. Furthermore, and perhaps more importantly, we seek to introduce a classification of insider transaction not used on Swedish data before with cluster transactions. LÄS MER
