1. 1. Vargen – ”en syndabock för större socioekonomiska problem” : en kritisk diskursanalys av nyhetsrapporteringen av varg på lokal och rikstäckande nivå

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Märtha Lindberg; [2023]
   Keywords : diskursanalys; landsbygd; media; varg; representationer;

   Abstract : Uppsatsens syfte är att kritisk granska och analysera nyhetsrapporteringen av rovdjursdiskursen för att urskilja hur olika maktstrukturer mellan stad och land syns och reproduceras i porträtteringen. Särskilt fokus ligger i den mediala bilden av landsbygd i vargfrågan där traditionella diskurser om landsbygd kan reproduceras snarare än utmanas i frågan. READ MORE

3. 2. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

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

   Author : Arvid Söderlund; [2023]
   Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

   Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

4. 3. Evaluation of Divider and Linear Interpolation Architectures on FPGAs

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Samuel Erlands; [2023]
   Keywords : FPGA;

   Abstract : The Field Programmable Gate Array (FPGA) is a platform with a unique set offeatures. It combines the programmability of general purpose computers with the flexibility of Application Specific Integrated Circuits (ASIC). Most basic operations have been thoroughly studied on ASICs and the best architecture for each operation has often been found. READ MORE

5. 4. Scann Loss Reduction on Phased Array Antenna

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

   Author : Wanyu Zhang; [2022]
   Keywords : Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

   Abstract : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. READ MORE

6. 5. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE
