  1. 1. The restoration period : a new era in forestry

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Ester Andersson; [2023]
    Keywords : historical forest management; past logging; restoration;

    Abstract : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. READ MORE

  3. 2. Selective Kernel Network based Crowding Counting and Crowd Density Estimation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jinchen Liu; [2023]
    Keywords : Crowding Counting; Convolution Neural Network; Selective kernel; Trängselräkning; konvolutionsneuralnätverk; Selektiv kärna;

    Abstract : Managing crowd density has become an immense challenge for public authorities due to population growth and evolving human dynamics. Crowd counting estimates the number of individuals in a given area or scene, making it a practical technique applicable in real-world scenarios such as surveillance and traffic control. READ MORE

  4. 3. 1900- talets skogsbruk i kronoparksskogar : en skogshistorisk studie om Håckren och Bjurfors kronoparker

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Therese Prestberg; [2020]
    Keywords : skogshistoria; Domänverket; skogsskötsel; skogsstruktur; Jämtland; Västmanland;

    Abstract : Industrialiseringen av Västeuropa och den efterföljande sågverksexpansion som inträffade i Sverige under 1800-talet påverkade de svenska skogarnas skötsel, struktur och funktion markant. Därmed introducerades nya avverkningsmetoder och debatter om den bästa skogsskötseln drevs. READ MORE

  5. 4. Properties of III-V/Si heterojunction fabricated by HVPE

    University essay from KTH/Tillämpad fysik

    Author : Prakhar Bhargava; [2020]
    Keywords : ;

    Abstract : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. READ MORE

  6. 5. Correlated Structure-Property Investigation of Ultrathin InAs Nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Linnea Suomenniemi; [2019]
    Keywords : Nanowires; InAs; epitaxy; MBE; Photo luminescence; Physics and Astronomy;

    Abstract : III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a key component in future nanoelectronic and nanophotonic applications and devices.
