  1. 1. Investigating off-grid systems for a mobile milking facility

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Musadag Mohamed Salah Eldin Elzein; [2021]
    Nyckelord :off-grid systems; renewable energy RE; Solar PV; biofuels; insight maker; HOMER;

    Sammanfattning : This study examined the possible renewable energy sources that can provide the necessary power for a mobile Off-grid Automated Milking System (AMS) at a grazing pasture. This involved choosing the most cost effective, environmental friendly and sustainable mean for a mobile AMS which aims to be operating between months of May to September at a rate of milking 20 cows per day.

  3. 2. Sumatranoshörningen (Dicerorhinus sumatrensis) på gränsen till utrotning - En riskanalys

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Amanda Gagné; [2021]
    Nyckelord :Sumatran rhinoceros; risk assessment; threats; conservation; Indonesia; Earth and Environmental Sciences;

    Sammanfattning : The critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. LÄS MER

  4. 3. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

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

    Författare :Siddharth Selvarajan; [2021]
    Nyckelord :Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

    Sammanfattning : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

  5. 4. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

  7. 5. Application of Deep Q-learning for Vision Control on Atari Environments

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Jim Öhman; [2021]
    Nyckelord :Reinforcement learning; Atari 2600; Deep Q-learning; Myopic Agents; Vision Control; Physics and Astronomy;

    Sammanfattning : The success of Reinforcement Learning (RL) has mostly been in artificial domains, with only some successful real-world applications. One of the reasons being that most real-world domains fail to satisfy a set of assumptions of RL theory. LÄS MER
