1. 1. The visibility of stellar transients in the Galactic Centre

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

   Författare :Jonathan Ström; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER

3. 2. Comparative Analysis of In-Body to Out-Body Wireless CommunicationModules: Test Design and PerformanceEvaluation

   Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Remya Sree Rema Bhai; Sisymol Stellus; [2024]
   Nyckelord :In-Body to Off-Body Communication; prototype; test-design; test protocol; medical device; wireless communication.;

   Sammanfattning : Wireless communication for biomedical equipment is rapidly improving with the invention of new technologies. Due to the absence of cables, wireless technology is a growing area of interest for biomedical applications. As technology advances, many gadgets are becoming smaller and more portable. LÄS MER

4. 3. Friktionsegenskaper hos snö och is

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Axel Ohrmér; [2024]
   Nyckelord :Friction; Friktion;

   Sammanfattning : Every year in the Nordic countries we are affected by winter road conditions. The roadsbecome unpredictable and many traffic accidents occur. This report aims to study thefriction on snow and ice and see how it is affected by different temperatures and surfaces. LÄS MER

5. 4. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Julia Martín-Fuertes Brañas; [2023]
   Nyckelord :2D Lattice Flower Constellation design; number of satellites; number of planes; revisit time; coverage; optimized constellation; target list; twin satellite concept; FreeFlyer; 2D Lattice Flower Constellation design; antal satelliter; antal plan; återbesökstid; täckning; optimerad konstellation; mållista; tvilling-satellit-koncept; FreeFlyer;

   Sammanfattning : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. LÄS MER

7. 5. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Muhammad Umar Farooq; [2023]
   Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

   Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER
