1. 31. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Ida Ljusell; [2023]
   Keywords : Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

   Abstract : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. READ MORE

3. 32. Language Theoretic Properties of Graph Extension Languages : An Investigation of Graph Extension Grammars with Context Matching and Logic

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Yannick Stade; [2022]
   Keywords : graph language; formal language; theoretical computer science;

   Abstract : Graph extension grammars provide a way to define graph languages. They consist of a regular tree grammar and an algebra. The regular tree grammar generates trees, so-called derivation trees. Those are evaluated by the algebra into a set of graphs. READ MORE

4. 33. Test and Calibration of CUBES: a CubeSat X-ray Detector

   University essay from KTH/Fysik

   Author : Caroline Holmberg; [2022]
   Keywords : Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

   Abstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE

5. 34. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Curt-Herman Normark Frisk; [2022]
   Keywords : Frequency Selective Surface; Microstrip Patch Element; Circular Polarisation; Phased Array Antenna; Single Feed; Frekvensselektiv Yta; Mikrostrip Patchelement; Cirkulär Polarisering; Fasstyrd Gruppantenn; Single-matad;

   Abstract : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. READ MORE

6. 35. Performance Analysis of Environmentally Adaptable Grease in Large open gears

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Victor Ogunmoye; [2022]
   Keywords : Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

   Abstract : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. READ MORE
