1. 1. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Nikolaos Kouskoulis; [2023]
   Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

   Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER

3. 2. Do Stocks Outperform Treasury Bills? Evidence From a Swedish Setting

   C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

   Författare :Anton Li; Ricky Yu; [2023]
   Nyckelord :Individual stocks; Treasury bills; Skewness; Buy-and-hold returns; Diversification;

   Sammanfattning : Most Swedish stocks listed since 1983 post lifetime buy-and-hold returns that are less than one-month Swedish Treasury bills. In terms of risk-adjusted returns for the same time horizon, individual Swedish stocks vastly underperform value-weighted benchmarks when measured with a Sharpe ratio. LÄS MER

   Sammanfattning : In gene editing, it is important to identify the number of edited and unedited nucleic acids in the development of new therapies and drugs. Countagen is developing a technology for accelerating genomic research and their product is called GeneAbacus. LÄS MER

5. 4. Disambiguating Italian homographic heterophones with SoundChoice and testing ChatGPT as a data-generating tool

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Matilde Nanni; [2023]
   Nyckelord :ChatGPT; Homograph disambiguation; Italian; SoundChoice;

   Sammanfattning : Text-To-Speech systems are challenged by the presence of homographs, words that have more than one possible pronunciation. Rule-based approaches are often still the preferred solution to this issue in the industry. LÄS MER

7. 5. Explainable Machine Learning in Cardiovascular Diagnostics

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

   Författare :Alexander Gutell; Ludvig Skare; [2023]
   Nyckelord :;

   Sammanfattning : The major challenges in implementing machine learning models in medical applications stemfrom ethical and accountability concerns, which arise from the lack of insight and understandingof the models' inner workings and reasoning. This opaqueness has resulted in the emergenceof a new subfield of machine learning called Explainability, which aims to develop and deploymethods to gain insight into how input data is weighted and propagated through a machinelearning algorithm.
