1. 1. Finding new members of the VelHel-4 stream

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Lucas Johansson; [2023]
   Keywords : Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

   Abstract : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. READ MORE

3. 2. Next Best Action : A clustering framework for Customer Relationship Management

   University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

   Author : William Takolander; [2022]
   Keywords : CRM; Clustering; Data analysis; Customer engagement;

   Abstract : For companies that supply a service to their customers, there will always be a difference in engagement from customer to customer. Some customers might have created an account, they might also have a paid subscription, or they neither have an account nor are a subscriber. Meaning that they only interact with the free content provided. READ MORE

4. 3. Technological progress and innovation, their decoupling effects on carbon emissions and economic growth exploring the environmental curve within the EU : A quantitative study

   Author : Petra Kreij; Georgios Margellos; [2022]
   Keywords : Carbon emissions; Decoupling; Environmental Curve; Economic Growth;

   Abstract : Climate change is one of the highest priority problems which needs to be addressed. The Paris Agreement focuses on zero-carbon solutions and to stop global warming while the United Nations highlights 17 sustainability goals. READ MORE

5. 4. Colliding Galaxies in a (Nut)Shell

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Jonathan Petersson; [2022]
   Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

   Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

6. 5. Evaluation of mini-grid versus stand-alone projects: a tool for decision-making on household connections in last-mile rural electrification projects

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Irene Noguera Alonso; [2022]
   Keywords : Last-mile rural electrification; isolated from the network; polygeneration; modelling; network design; costs; mini-grid; stand-alone system; investment costs; Sista milen elektrifiering p˚a landsbygden; isolerad fr˚an n¨atverket; polygeneration; modellering; n¨atverksdesign; kostar; minin¨at; frist˚aende system; investeringskostnade;

   Abstract : Electrification of isolated rural areas in developing countries is a key action for the total eradication of energy poverty. A growing number of authors argue that this electrification should be done with distributed energy systems that combine different renewable energy sources, rather than trying to reach these communities with grid extensions.
