  1. 1. Biflödens effekt på mångfald och abundans av växter i strandzonen utmed älvar : Test av hydrochorins effekt och den longitudinella teorin

    Kandidat-uppsats, Karlstads universitet

    Författare :Daniel Berger; [2023]
    Nyckelord :biology; ecology; hydrochory; plants; biological diversity; riparian; riparian zone; river collector hypothesis; ume river; vindel river; biologi; ekologi; hydrochori; växter; biologisk mångfald; strandzon; kantzon; river collector hypothesis; umeälven; vindelälven;

    Sammanfattning : The riparian zone is a changeable and species-rich habitat with important ecological functions that have long been affected by human activities such as hydropower and forestry. Rivers and their adjacent riparian zones also constitute a transport route for plant parts and seeds in a form of passive transport, called hydrochory, which can contribute to the establishment of plants or the preservation of diversity in the riparian zone.

  3. 2. Planera för framkomlighet med fokus på signalprioritering

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Linus Bergman; [2021]
    Nyckelord :brt; bhls; tram; signal priority; tsp; passability; priority; Technology and Engineering;

    Sammanfattning : För skapa ett transporteffektivt samhälle kommer kollektivtrafiken att spela en allt större roll i framtidens transportsystem. Om kollektivtrafiken utgör ett reellt alternativ till bilen kan den bidra till både sänkta utsläpp av växthusgaser och marknära partiklar och bidra till en mer effektiv användning av stadens yta.

  4. 3. A comparison of supervised and semi-supervised learning for classification of truck stop locations

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mengdi Xue; [2021]
    Nyckelord :;

    Sammanfattning : GPS-based data has been an important source for researchers and commercial fleet companies to study and build transportation models, since GPS uses passive information collecting without including too much human participation, and thus provides the possibility of collecting huge amount of data. Recent research shows that the GPS data can be used to solve different kinds of transportation related problems using machine learning algorithms. LÄS MER

  5. 4. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Diana Jonsson; [2021]
    Nyckelord :Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

    Sammanfattning : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. LÄS MER

  7. 5. Coulomb drag in parallel nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :David Dai; [2020]
    Nyckelord :Coulomb drag; nanowire; Physics and Astronomy;

    Sammanfattning : In this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. LÄS MER
