  1. 1. Quantum Optical Description of High-order Harmonic Generation

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

    Author : Isabel Moreno; [2024]
    Keywords : Physics and Astronomy;

    Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  3. 2. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    University essay from KTH/Kemi

    Author : Arezu Sehati; [2023]
    Keywords : Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Abstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

  4. 3. Comparison of drone ecology and behavior between Apis mellifera mellifera and the hybrid Buckfast in southwestern Sweden

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Finja Schaumann; [2023]
    Keywords : ;

    Abstract : Most research on the biology of the western honey bee (Apis mellifera) focuses on the worker bees, but knowledge about drones is lacking despite their important role in mating with a virgin queen. Available information about their ecology and behavior are mainly based on direct observations in need of intensive experience and knowledge about honey bees. READ MORE

  5. 4. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hoda Mahmoodi; [2023]
    Keywords : Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

    Abstract : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. READ MORE

  6. 5. Top-down cost assessment and market regulatory conditions affecting BESS feasibility in the Spanish framework : Exploring the viability of utility-scale stand-alone Battery Energy Storage Systems in Spain

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

    Author : Pere Abelló Sunyer; [2023]
    Keywords : Battery Energy Storage Systems BESS ; Regulatory framework; Operational optimization; Economic viability;

    Abstract : This thesis report provides a comprehensive analysis of the regulatory landscape governing Battery Energy Storage Systems (BESS) in Spain and offers insights into their operational optimization and economic viability. The study centers on a 40 MW BESS and explores three distinct case studies, each representing varying system durations (one, two, and four hours) and two different electricity price scenarios (2019 and 2022).
