  1. 1. 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. 2. Solar PV and Lithium-ion BESS for Commercial Buildings in Sweden : Techno-economic evaluation of Peak Shaving, Energy Arbitrage and Frequency Regulation as management strategies.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Zacharias Sköld; [2023]
    Keywords : Li-BESS; Solar PV; Commercial buildings; Management; Frequency Regulation; Lithium-jon-batterier; Solceller; Kommersiella Byggnader; Styrstrategier; Frekvensreglering;

    Abstract : The residential and commercial sector is the largest consumer of electricity in Sweden and therefore highly affected by fluctuations in electricity price. On the other hand, there is a large potential to reduce both the electricity demand and emissions from electricity generation on a national level if measures are taken within this sector. READ MORE

  5. 4. Synthetic gel particle formation for acoustofluidic applications

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Thibaut Valery; [2022]
    Keywords : agarose gel particles; acoustofluidics; droplet generation; microfluidic chip; Technology and Engineering;

    Abstract : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. READ MORE

  6. 5. Computationally Efficient Methods in Topology Optimization

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Vilmer Dahlberg; [2022]
    Keywords : Topology Optimization; Eigenfrequency; Eigenmode; Reduced Order Model; Sensitivity Analysis; Deflation; Technology and Engineering;

    Abstract : In topology optimization, iterative, gradient-based methods are used to find the material distribution of structures which maximizes some objective function, typically the structures' stiffness, or in some cases the fundamental frequency. Finite element analysis is used to compute the structural response in each iteration, leading to large systems of equations. READ MORE
