1. 1. Triaxialförsök och utvärdering av parametrar för modellering : Anrikningssand med sprött beteende

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

   Författare :Lukas Haga; [2024]
   Nyckelord :Geoteknik; Triaxialförsök; Anrikningssand; Gruvdamm; Statisk liquefaction; NorSand; Utvärdering; Parametrar;

   Sammanfattning : Efter det dammbrott som skedde vid Brumadinho i Brasilien under januari 2019, där hundratals människor miste sina liv, har frågor kring statisk liquefaction hos anrikningssand fått stort fokus inom gruvdammsindustrin.  Statisk liquefaction kan modelleras med den konstitutiva modellen NorSand, där NorSand-parametrarna kan utvärderas från triaxialförsök.

3. 2. Initial Development and Validation of Language-Based Assessments for Meaningful Change

   Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

   Författare :Ulrika Söderström; [2024]
   Nyckelord :meaningful change; depression; Large Language Models; AI; Social Sciences;

   Sammanfattning : Meaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. LÄS MER

4. 3. Comparing the Locality Preservation of Z-order Curves and Hilbert Curves

   Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Alex Nordin; Adam Telles; [2023-08-03]
   Nyckelord :space-filling curve; software engineering; software testing;

   Sammanfattning : Developing and testing software in the automotive industry and in the research of autonomous vehicles requires the costly querying of multidimensional data recorded from such a vehicle’s various sensors. Through encoding such data using space filling curves, faster queries could be achieved by reducing multiple dimensions into a singular dimension, while exploiting the patterns that emerge in the one-dimensional representation to still get accurate search results.

5. 4. Detection and Analysis of Anomalies in Tactical Sensor Systems through Structured Hypothesis Testing

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

   Författare :Fredrik Ohlson; [2023]
   Nyckelord :Tactical sensor systems; Sensor fusion; Model based diagnostics; Hypothesis testing; Taktiska sensor system; Sensor fusion; Modellbaserad diagnostisering; Hypotesprövning;

   Sammanfattning : The project explores the domain of tactical sensor systems, focusing on SAAB Gripen’s sensor technologies such as radar, RWR (Radar Warning Receiver), and IRST (InfraRed Search and Track). The study employs structured hypothesis testing and model based diagnostics to examine the effectiveness of identifying and isolating deviations within these systems. LÄS MER

7. 5. Predictability of Shareholder Return in Medical Device Companies : Investment Decisions from thePerspective of an Investment Firm

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Daniel Gröttheim; [2023]
   Nyckelord :Medical device companies; pre-market approval; total return; abnormal return; stock return prediction; market anomalies; free cash flow yield; efficient markets; financial crisis; investment firm; Medicintekniska företag; förmarknadsgodkännande; totalavkastning; abnorm avkastning; aktieavkastningsförutsägbarhet; marknadsavvikelser; avkastning på fritt kassaflöde; effektiva marknader; finanskris; investeringsföretag;

   Sammanfattning : The medical device industry has seen rapid growth in recent years, and the increasing valuations has caught the attention of investors. Although their growth has outpaced many indices, medical device companies’ reliance on capital to finance research, patents, and clinical testing to reach pre-market approval makes due-diligence and the investment research process especially complex.
