1. 1. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Amal Vinod; [2023]
   Nyckelord :Volumetric rendering; rendering; Comet; Coma; Dust Coma; Gas Coma; Blender; Comet Interceptor;

   Sammanfattning : The Comet Interceptor is a joint mission by European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) which seeks to perform a flyby over a Long Period Comet using a multi-element spacecraft. The Comet Interceptor comprises three spacecrafts- A, B1 and B2. LÄS MER

3. 2. Design of a modular small-scale PMMA/Air hybrid rocket research engine

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Gustaf von Platen; [2023]
   Nyckelord :hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

   Sammanfattning : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.

4. 3. Dynamic Mixed Reality AssemblyGuidance Using Optical Recognition Methods

   Master-uppsats, KTH/Industriell produktion

   Författare :Harpa Hlíf Guðjónsdóttir; Gestur Andrei Ólafsson; [2022]
   Nyckelord :Manufacturing; Mixed Reality; Augmented Reality; Assembly Guidance; Object Recognition; HoloLens 2; Vuforia Engine; Unity; Mixed Reality Toolkit; Tillverkning; Blandad Verklighet; Förstärkt Verklighet; Monteringsvägledning; Objektigenkänning; HoloLens 2; Unity; Vuforia Engine; Mixed Reality Toolkit;

   Sammanfattning : Mixed Reality (MR) is an emerging paradigm in industry. While MR equipment and software have taken great technological strides in past years, standardized methods and workflows for developing MR systems for industry have not been widely adopted for many tasks. This thesis proposes a dynamic MR system for an assembly process. LÄS MER

5. 4. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Birgir Steinn Hermannsson; [2022]
   Nyckelord :;

   Sammanfattning : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. LÄS MER

7. 5. Form data enriching using a post OCR clustering process : Measuring accuracy of field names and field values clustering

   Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

   Författare :Adil Aboulkacim; [2022]
   Nyckelord :Optical Character Recognition; Form Processing; Data enrichment; Optisk teckenläsning; Formulärbearbetning; Databerikning;

   Sammanfattning : Med OCR teknologier kan innehållet av ett formulär läsas in, positionen av varje ord och dess innehåll kan extraheras, dock kan relationen mellan orden ej förstås. Denna rapport siktar på att lösa problemet med att berika data från ett strukturerat formulär utan någon förinställd konfiguration genom användandet utav klustring. LÄS MER
