  1. 21. Calibration in Urban Building Energy Modeling

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Naeim Rashidfarokhi; [2021]
    Nyckelord :;

    Sammanfattning : This thesis work tries to study the annual calibration process for building performance simulations. The bottom-up modelling is a tool to predict energy consumption in Urban Building Energy Modeling (UBEM) which is a common approach to find the most appropriate retrofitting strategies or to monitor energy use for a group of buildings (an archetype), a neighbourhood or a city.

  3. 22. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emmanuel Ekwu; [2021]
    Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER

  4. 23. Material characterization of long-term stress relaxation in a semi-crystalline polymer material : An experimental and numerical study

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola

    Författare :Jakob Görtz; [2021]
    Nyckelord :Abaqus; MCalibration; PRF; HDPE; Stress relaxation; Long-term testing; Theoretical expressions; Material calibration;

    Sammanfattning : As the plastic and packaging industry is looking to increase the longevity of plastic products as well as recycling used material, there is a need to understand how material properties respond and change during long periods of mechanical loading. Physical tensile experiments on thin plant-based High-Density Polyethylene (HDPE) are conducted with the intent of capturing relaxation behavior from a short-term (1-3 hours) and long-term (29-56 days) perspective.

  5. 24. A Tension between the Early and Late Universe: Could Our Underdense Cosmic Neighbourhood Provide an Explanation?

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Sveva Castello; [2021]
    Nyckelord :Cosmology; Hubble tension; local void;

    Sammanfattning : In recent years, the increasingly precise constraints on the value of the Hubble constant, H0, have highlighted a discrepancy between the results arising from early-time and late-time measurements. A potential solution to this so-called Hubble tension is the hypothesis that we reside in a cosmic void, i.e. LÄS MER

  7. 25. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Frida Ekman; [2021]
    Nyckelord :Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

    Sammanfattning : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.
