1. 1. Förlusten av animalitet : En undersökning av det levande i och bortom ett människodjurs yrkesliv

   Master-uppsats, Södertörns högskola/Centrum för praktisk kunskap

   Författare :Åse Teiner; [2023]
   Nyckelord :practical knowledge; animality; human animality; animalistic professional practice; posthumanism; diffraction; agential realism; education; digital education; dog; praktisk kunskap; animalitet; mänsklig animalitet; animalistisk yrkesutövning; posthumanism; diffraktion; agentiell realism; utbildning; digital utbildning; hund;

   Sammanfattning : Denna vetenskapliga essä utforskar begreppet animalitet som en aspekt av det levande som människan delar med andra djur. Essän tar sin utgångspunkt i en protest mot hur människan som djur begränsas inom yrkeslivet. LÄS MER

3. 2. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Reza Doulati; [2023]
   Nyckelord :vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

   Sammanfattning : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. LÄS MER

4. 3. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits

   Master-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

   Författare :Jens Henriksson; [2022]
   Nyckelord :Kiruna-type deposit; electron backscattered diffraction; crystal settling; Fe-O systematics; crystal alignment;

   Sammanfattning : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. LÄS MER

5. 4. RayTracing Analysis and Simulator Design of Unmanned Aerial Vehicle Communication and Detection System in Urban Environment

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

   Författare :Jie Huang; [2022]
   Nyckelord :Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

   Sammanfattning : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. LÄS MER

7. 5. Raytracing in Channel Model Development

   Master-uppsats, Karlstads universitet

   Författare :Andreas Rogne; [2022]
   Nyckelord :;

   Sammanfattning : The fifth generation of mobile internet is upon us, but still, there is work to do before the new technology is fully utilized. The new generation of cellular network promises frequencies ranging from the sub – 6 GHz to 39 GHz, the latter being in the mmWave spectrum. LÄS MER
