1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER
2. Har signalarter störst förekomst inom eller utanför Dalarnas boreala naturreservat? : En studie om arttätheten av signalarter i Dalarnas barrskogar
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Today, it is well known that biological diversity is decreasing worldwide, and the presence of indicator species can identify areas with high biological diversity. Environments with a high presence of indicator species are important to protect and preserve in the form of, for example, nature reserves as these environments indicate high nature values. LÄS MER
3. Constraining the Higgs width in Higgs production associated with a top quark pair
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

4. Gunshot Detection and Direction of Arrival Estimation Using Machine Learning and Received Signal Power
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : Poaching is a persistent issue that threatens many of earth’s species including therhino. The methods used by poachers are varied, but many use guns to carry outtheir illegal activities. Gunfire is extremely loud and can be heard for kilometres. LÄS MER
5. Effects of clear-cut logging on five old-growth forest bryophyte species. : How does the most common forestry method in Sweden impact vulnerable forest specialists?
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Clear-cut logging is the most widely practised forestry method in Sweden. This often conflicts with nature conservation and leads to issues where economic interests are pitted against ecological values. LÄS MER
