  2. 1. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    Author : Oscar Stål; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; Elementary particle physics; Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE

  4. 2. Studies of Top Physics Sensitivity and of Pile-Up Effects on Energy Reconstruction in the ATLAS Detector : A Licentiate Thesis About the Treatment of Troublesome $\tau$ and Producing Pulses to Probe Pile-up Problems

    Author : Simon Molander; Sten Hellman; Jörgen Sjölin; Klas Hultqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tau; top quark; ATLAS; LHC; TILE calorimeter; sensitivity; cross-section; standard model; physics; optimal filtering; energy reconstruction; hadronic tau decay; fysik; Physics;

    Abstract : This thesis presents two studies conducted using the ATLAS detectorat the Large Hadron Collider. The first one is a technical study abouthow out-of-time pile-up affects energy reconstruction using the optimalfiltering 2 algorithm in the TILE calorimeter sub detector. The studyis conducted using a pulse simulator software that is also described. READ MORE

  5. 3. Regulating energy performance of residential buildings in cold climate : a study of indicators, criteria, and evaluation methods

    Author : Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy performance; building simulation; cold climate; energy use; indicators; evaluation methods; building regulations; residential buildings; energy measurements; performance gap; energy signature; sustainable development; hållbar utveckling; fysik; Physics;

    Abstract : Building energy performance has been important in Fennoscandia ever since the early vernacular houses, to combat the cold climate. Due to EU directive 2010/31/EU on the energy performance of buildings (EPBD recast), building energy performance has become even more relevant in northern Europe the last decade. READ MORE

    Abstract : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. READ MORE

  7. 5. Design of Thermal Energy Storage with Phase Change Materials - Investigations within Material, Device and System Scale

    Author : Pepe Tan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; T-History; Phase Change Materials; Thermal Energy Storage; Experimentation;

    Abstract : The addition of a thermal energy storage (TES) into a process allows the operator to store and release thermal energy on demand. This increased process flexibility leads to potential benefits such as shifting energy demand from peak to off-peak hours. READ MORE
