  1. 1. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

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

    Author : Saga Westerberg; [2023]
    Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

  3. 2. Dark pathways : cows’ walking behavior in dim light environments

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Kajsa Ståhlberg; [2022]
    Keywords : night light; illumination; locomotion; activity; intensity; color; distribution; obstacle course;

    Abstract : Swedish dairy cows should have access to dim light at night according to the animal welfare act, but there are no further recommendations stated for dim light management regarding light intensity, light color, or light distribution. This study aimed to examine the effects of five dim light intensities, in red and white light color, and in even and uneven light distribution on cows’ walking behavior in an obstacle course.

  4. 3. The sensitivity of the EMC algorithm to the light intensity and amount of diffraction patterns in diffraction experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Molekylär biofysik

    Author : Johanna Rogvall; [2021]
    Keywords : Diffraction; EMC; coherent diffraction imaging; Condor; XFEL;

    Abstract : To understand the function of macromolecules like proteins it helps to know the structure of the molecule. Coherent diffraction imaging is an emerging method that might be used to figure out the structures of macromolecules. READ MORE

  5. 4. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles

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

    Author : Jonathan Peterson; [2020]
    Keywords : Scheimpflug Lidar; Lidar; Bark beetles; Forestry; Entomological monitoring; Physics and Astronomy;

    Abstract : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. READ MORE

  6. 5. Ljusets och mörkrets effekt på suggor och gyltor : reproduktion, produktion och välfärd

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Julia Carlsson; [2020]
    Keywords : ljusperiod; ljus intensitet; artificiell belysning; säsongsbunden infertilitet; laktation; grisning;

    Abstract : Det är av stor ekonomisk betydelse för lönsamheten i en intensiv grisproduktion att ha fungerande reproduktion och produktion av smågrisar. Syftet med denna litteraturstudie är att undersöka vilken effekt ljus och mörker har för suggor och gyltor i olika produktionsstadier samt inverkan av ljusperiod eller ljusintensitet. READ MORE
