  1. 1. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Tanja Cernosa; [2020]
    Keywords : Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Abstract : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

  2. 2. An annual evaluation of CH4 oxidation in a freshwater lake

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Eldina Cehic; [2020]
    Keywords : Methane oxidation; isotopic fractionation; stratification; open steady-state and closed system.; Metanoxidation; isotopfraktionering; stratifiering; öppet stabilt system och stängt system;

    Abstract : Freshwater lakes constrain its methane (CH4) emissions through CH4 oxidation. CH4 includes three carbon (C) isotopes; the stable isotopes 12C,13C and the unstable and more uncommon isotope 14C. Methanotrophs (i.e. READ MORE

  3. 3. The Influence of Cavity Widths and Lateral Ventilation Conditions on the Fire Behaviour within a Non-Combustible Ventilated Façade System

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Daniel Fogerty; [2020]
    Keywords : Technology and Engineering;

    Abstract : Present uncertainties in key ventilation parameters, characterising the fire performance of facades, has necessitated clarification in the foundational understanding of the Fire Science Body of Knowledge. A test program conducted in collaboration between Lunds Universitet and the Kingspan Group, studied the influence of cavity widths and lateral ventilation conditions on the fire behaviour within Intermediate-scale ventilated façades following the ISO 13785-1 standards.

  4. 4. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Markus Back; [2020]
    Keywords : Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Abstract : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. READ MORE

  5. 5. Understanding the Northern pike (Esox lucius) through accelerometer, is it possible?

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Oskar Andersson; [2020]
    Keywords : ;

    Abstract : Accelerometer biologgers är ett verktyg för att identifiera beteenden hos djur. För att kunna använda accelerometern effektivt är det viktigt att träna en maskin–inlärning algoritm för att kunna identifiera olika beteenden utifrån accelerations data. READ MORE
