  1. 1. Design of high performance buildings : Vulnerability of buildings to climate change from an energy perspective

    University essay from KTH/Hållbara byggnader

    Author : Robin Gobert; [2022]
    Keywords : Climate Change; High Performance Buildings; Dynamic Thermal Simulations; Thermal Regulation; Environmental Regulation; Cooling Needs; Heating Needs; Representative Data; Big Data; Clustering;

    Abstract : The challenge of climate change is twofold: to mitigate (prevent) the causes of climate change and to prepare (adapt) to the inevitable effects and consequences. Building and construction are key sectors for decarbonisation (mitigation). READ MORE

  2. 2. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Author : Tim Günter; [2022]
    Keywords : ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Abstract : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. READ MORE

  3. 3. Fire Risk and Hazard Analysis of Lithium-Ion Battery Technologies in Underground Facilities: A Literature Review

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Sean Meehan; [2022]
    Keywords : lithium-ion battery; hazards; risks; thermal runaway; detection; fire protection; Technology and Engineering;

    Abstract : The past decades have seen an exponential growth of the lithium-ion battery (LIB) market as use of this high-energy storage has found applications in nearly every industry. The European Organization for Nuclear Research (CERN) is interested in implementing this technology within their underground network and this literature review is intended to assist with addressing fire and safety concerns.

  4. 4. Photophysics of the polymer acceptor PF5-Y5 in organic photovoltaics : A first principles theory based study

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Anton Almén; [2022]
    Keywords : PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamental; optical; gap; oxidation; reduction; exciton; binding; energy; oligomer; length; PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamentalt; optiskt; gap; oxidation; reduktion; exciton; binding; energi; oligomerlängd;

    Abstract : Non-fullerene Acceptors (NFAs) have gathered a great deal of interest for use inorganic photovoltaics (OPVs) due to recent breakthroughs in their power conversion efficiency and other advantages they offer over their Fullerene-based counterparts. In this work, a new promising non-fullerene polymer acceptor, PF5-Y5, have been studied using density functional theory and time-dependent density functional theory; and the effects that oligomer length, geometry relaxation and exchange-correlation interaction has on the exciton binding energies (the difference between optical and fundamental energy gaps) have been investigated.

  5. 5. Desert garden techniques to ameliorate urban microclimates : an example of application in Granada, Spain

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Otto Lundberg; [2022]
    Keywords : climate change; Egyptian gardens; Persian gardens; Alhambra; urban heat island; desert gardens;

    Abstract : In this day and age we are faced with urban cores getting hotter, with the main drivers being climate change and the urban heat island effect. This gets even more complicated as the parts of Europe that have the largest need too cool down, i.e. the south, has the least amount of space available for interventions in the form of green space.
