  1. 26. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Clementsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  3. 27. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Ângelo Miguel Mendes Ferreira; [2023]
    Keywords : biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Abstract : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

  4. 28. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

    University essay from KTH/Materialvetenskap

    Author : Mochen Li; [2023]
    Keywords : Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

    Abstract : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. READ MORE

  5. 29. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Nathan Groisne; [2023]
    Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Abstract : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. READ MORE

  6. 30. Bridging the GAP for knowledge creation in an international project : A qualitative case study for SIREUS, a SACC-USA program

    University essay from Jönköping University/Internationella Handelshögskolan

    Author : Erika Villumsen; Louise Murphy; [2023]
    Keywords : Knowledge management; tacit knowledge; explicit knowledge; knowledge creation; knowledge creation in projects; International projects;

    Abstract : Background:The management of knowledge within organizations and projects has become increasinglyimportant. In addition, the number of transnational projects is on the rise. Moreover, projectsare considered the loci where new knowledge is generated. READ MORE
