1. 6. Black Hole Dynamics in Stellar Clusters

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Markus Strickert; [2022]
   Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

3. 7. Energy efficiency measures in a typical Swedish single-family building from the 1960s

   University essay from Uppsala universitet/Byggteknik och byggd miljö

   Author : Emanuel Larsson; Raffaello Ljungqvist Baldesi; [2022]
   Keywords : energy system; building; energy efficiency measures; storage; solar panels; electricity demand; heating demand; insulation;

   Abstract : Many buildings built in the 1960s are inefficient when it comes to their energy use. A lot of them are also in need of renovating. Therefore, this project is aiming to investigate five different scenarios where the decrease in electricity demand is in focus. READ MORE

4. 8. A reverse data-driven energy estimation approach for evaluating renewable energy systems implementation in New York City

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Seyedmohammad Hosseini; [2021]
   Keywords : Energy use prediction; Energy performance simulation; Renewable energy source; data-driven energy estimation; Statistical methods; Reverse method; Regression model; Urban modelling; Energy modelling; Generative modelling; Geothermal heat pump; Borehole Thermal Energy Storage.; Technology and Engineering;

   Abstract : Urban areas are responsible for a significant part of greenhouse gas emissions. Megacities, especially, have cumulative impacts due to different anthropogenic heat sources and urban heat island phenomena. It is therefore vital to replace fossil fuel burning heating sources with renewable sources in the current building stock. READ MORE

5. 9. A Framework for Assessment of and Advancement Towards Sustainable Circular Economy : An application on automotive brake calipers

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Alva Helin; [2020]
   Keywords : Life Cycle Assessment; Material Flow Analysis; Remanufacturing; Circularity; Livscykelanalys; Materialfl ̈odesanalys; Renovering; Cirkularitet;

   Abstract : The current use of natural resources within the industry generally constitutes of linear systems of raw material extraction to waste formation. However, an increased awareness of sustainability issues has resulted in engagements to try to minimise the impacts on the environment that these linear systems impose. READ MORE

6. 10. To waste, or to resource? A comparative Life Cycle Assessment of recovering bottom ash from waste incineration for use in road construction in Malmö.

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Fynn Peter Hauschke; [2020]
   Keywords : Life Cycle Assessment LCA ; waste incineration; bottom ash; secondary material; road construction; Earth and Environmental Sciences;

   Abstract : The low-carbon benefits and emissions savings from circular economy (CE) strategies are not yet well understood, yet are crucial for global development within Planetary Boundaries. Using the mineral fraction of waste incinerator bottom ash (MIBA) as construction material in road construction is one application of a CE strategy that could lead to environmental gains by substituting energy-intensive primary material and avoiding its alternative disposal in a landfill.
