1. 21. Reflection Seismic Survey for Characterising Historical Tailings and Deep Targeting at the Blötberget Mine, Central Sweden

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :EMMANUEL ALOFE; [2021]
   Nyckelord :reflection seismic; exploration; tailings; sustainability; circularity; tomography; reflektion seismisk; prospektering; gruvavfall; hållbarhet; cirkularitet; tomografi;

   Sammanfattning : Iron has been an essential element to human development and iron-oxide deposits are known to host minerals that are labelled as critical raw materials (CRMs), especially in the EU. Therefore, ensuring a sustainable supply of CRMs require access to both primary and secondary sources of their host deposits such as iron oxides. LÄS MER

3. 22. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

   Författare :Victor Kingstad; [2020]
   Nyckelord :UAV; forestry; inventory; survey; cleaning; tending; PCT; pre com-mercial thinning;

   Sammanfattning : After more than three decades of advanced technology and methods to evaluate young forest attributes, the forestry still prefers laborious field surveys in regenera-tion forests. Preceding studies have virtually all successfully identified the saplings, but the cost has outweighed the benefits or at least not yet convinced the companies to step away from the traditional field surveys; high-resolution photogrammetric point clouds and ALS-data can provide accurate estimations of the biophysical prop-erties but requires intense data processing.

4. 23. Analysis of bladder cancer treatment plans generated for online adaptive radiotherapy and validation of an integrated independent dose calculation software

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Daria Badika; [2020]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Purpose: In 2019 Varian EthosTM linear accelerator (Varian Medical Systems, CA, USA) with integrated artificial intelligence (AI) was installed at Herlev Hospital, Copenhagen, Denmark, enabling online adaptive radiotherapy (oART) e.g for bladder cancer patients with a large margin reduction.

5. 24. Differentiation of the history of ideas and delineation of the history of knowledge in Sweden 2015 - 2020

   Kandidat-uppsats, Stockholms universitet/Institutionen för kultur och estetik

   Författare :Sverker Högberg; [2020]
   Nyckelord :Boundary-work; Discipline formation; Field formation; History of ideas; History of knowledge; History of science; Intellectual history; Sweden; Idéhistoria; Kunskapshistoria; Vetenskapshistoria; Disciplinbildning; fältbildning; idéhistoria; kunskapshistoria; vetenskapshistoria; Sverige;

   Sammanfattning : This essay analyses the development of field and discipline formation in Sweden. A specific case is presented regarding the differentiation of the history of ideas, idéhistoria, and the delineation of the history of knowledge, kunskapshistoria, between 2015 and 2020. LÄS MER

7. 25. Automation of Kidney Perfusion Analysis from Dynamic Phase-Contrast MRI using Deep Learning

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Andrés Martínez Mora; [2020]
   Nyckelord :Deep Learning; Segmentation; Kidney Imaging; MRI; Flow Analysis; Chronic Kidney Disease;

   Sammanfattning : Renal phase-contrast magnetic resonance imaging (PC-MRI) is an MRI modality where the phase component of the MR signal is made sensitive to the velocity of water molecules in the kidneys. PC-MRI is able to assess the Renal Blood Flow (RBF), which is an important biomarker in the development of kidney disease. LÄS MER
