  1. 1. Topology optimization: perimeter restriction using total variation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Jonas Fredriksson; [2022]
    Nyckelord :Topology optimization; structural optimization; solid mechanics; total variation; Technology and Engineering;

    Sammanfattning : Topology optimization is a method used to find optimal material distributions, within a specified domain, with respect to some performance measure. To avoid various artifacts to appear in the suggested design, the solution space is typically restricted, where some restriction methods allow different length scales to be controlled in the design.

  2. 2. Förvaltning av enskilda vägar med fokus på skogsbygdens vägar

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fastighetsvetenskap

    Författare :Jens Pettersson; [2022]
    Nyckelord :Enskild väg; gemensamhetsanläggning; förvaltning; båtnadsområde; samordning; samfällighetsförening.; Technology and Engineering;

    Sammanfattning : The aim of this paper is to improve the management of joint facilities and private roads. This was done by identify and investigat different problems connected to the private road organisations, formed through the regulation of joint facility and associations connected to them. LÄS MER

  3. 3. Exploiting Spatial Redundancy and Approximate Computing for Area Efficient Image Compression

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Saurav Arjun; [2022]
    Nyckelord :Image Compression; VLSI; Spatial redundancy; DCT; Compression; System Verilog; Technology and Engineering;

    Sammanfattning : Owing to the intensive computation involved in the Discrete Cosine Transform during image com- pression, the design of the efficient hardware architectures for fast computation of the transform has become imperative, especially for real-time applications. Although fast computation techniques have been able to minimise the hardware computation complexity to a certain limit, they could further extend the research to figure out the interesting approaches which can be implemented on applications where power, speed and area are crucial factors to determine the performance of the system.

  4. 4. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER

  5. 5. Föråldrad lagstiftning och traditionell bransch - hur kan fastighetsbranschen bemöta utmaningarna med delade ytor?

    Master-uppsats, Lunds universitet/Fastighetsvetenskap

    Författare :Jakob Johansson Streijffert; Ella Svensson; [2022]
    Nyckelord :affärsmodell; delningsekonomi; delningskoncept; hyreslagen; hyresavtal; kommersiella fastigheter; kommersiella lokaler; mervärdesskattelagen; moms; coworking; delade ytor; samutnyttjade ytor; cirkulär ekonomi; frivillig skattskyldighet; flexibla avtal; Technology and Engineering;

    Sammanfattning : Delningsekonomi är ett växande fenomen i samhället. Kortfattat handlar delningsekonomi om att använda underutnyttjade resurser bättre genom att dela. Att dela ytor kan innebära en mer effektiv användning av befintliga byggnader vilket potentiellt kan minska behovet av nyproduktion. LÄS MER
