  1. 21. Granbarkborreangrepp i och kring naturreservat : hur påverkar åtgärder?

    University essay from SLU/Dept. of Ecology

    Author : Martin Erik Westerling; [2023]
    Keywords : Ips typographus; granbarkborre; åttatandad barkborre; naturreservat; naturskydd; randbarkning; barkning; skogsbruk; utbrott; bekämpning;

    Abstract : Granbarkborren (Ips typographus) orsakar en stor skada i dom svenska skogarna. Från dom senaste 120 åren finns data som visar många av dom större granbarkborreangreppens påverkan. Inget utbrott finns registrerat som går att jämföra med det utbrott som startade efter den rekordvarma sommaren 2018. READ MORE

  3. 22. Head-to-head Transfer Learning Comparisons made Possible : A Comparative Study of Transfer Learning Methods for Neural Machine Translation of the Baltic Languages

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Mathias Stenlund; [2023]
    Keywords : machine translation; transfer learning; Latvian; Lithuanian; low-resource languages; transformers; parent language; child language; comparative study;

    Abstract : The struggle of training adequate MT models using data-hungry NMT frameworks for low-resource language pairs has created a need to alleviate the scarcity of sufficiently large parallel corpora. Different transfer learning methods have been introduced as possible solutions to this problem, where a new model for a target task is initialized using parameters learned from some other high-resource task.

  4. 23. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  5. 24. Exploratory study of ion pair liquid chromatography separation methods and sample preparation procedures – for quantification of amount 5’capped and uncapped mRNA

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Felicia Lindström; [2023]
    Keywords : ;

    Abstract : Using ion pair chromatography, separation and analysis of shorter mRNA fragments was possible. The aim of the study was to develop a separation method for quantitation of 5’capped versus uncapped mRNA. Cleavage of mRNA was performed by complementary probes and the enzyme RNase H which created shorter mRNA fragments containing the 5’ end. READ MORE

  6. 25. 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.
