1. 1. Ärendehantering genom maskininlärning

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Daniel Bennheden; [2023]
   Nyckelord :Artificial Intelligence; machine learning; case management; RPA; Random forest; Naïve Bayes; support vector machine; neural network; Artificiell Intelligens; maskinlärning; ärendehantering; RPA; Random forest; Naïve Bayes; support vector machine; neurala nätverk.;

   Sammanfattning : Det här examensarbetet undersöker hur artificiell intelligens kan användas för att automatisktkategorisera felanmälan som behandlas i ett ärendehanteringssystem genom att användamaskininlärning och tekniker som text mining. Studien utgår från Design Science ResearchMethodology och Peffers sex steg för designmetodologi som utöver design även berör kravställningoch utvärdering av funktion. LÄS MER

3. 2. Probability of Default Machine Learning Modeling : A Stress Testing Evaluation

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Tobias Andersson; Mattias Mentes; [2023]
   Nyckelord :Probability of Default; Machine Learning; Stress Testing; Logistic Regression; Decision Tree; Random Forest; Artificial Neural Network;

   Sammanfattning : This thesis aims to assist in the development of machine learning models tailored for stress testing. The main objective is to create models that can predict loan defaults while considering the impact of macroeconomic stress. LÄS MER

4. 3. The restoration period : a new era in forestry

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Ester Andersson; [2023]
   Nyckelord :historical forest management; past logging; restoration;

   Sammanfattning : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. LÄS MER

5. 4. “It was a free and healthy job” : timber floating on the river Ångermanälven in the 20th century

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Olivia Forssén; [2023]
   Nyckelord :timber floating; forest history; women in timber floating; interviews; historical records;

   Sammanfattning : The exploitation of northern Sweden's forests began in about the 1830s and continued expanding northwards over the following decades. A key factor that enabling the exploitation of these forests was the natural infrastructure, such as the network of rivers, creeks and flooding during the summer, which made it possible to float timber from the forests to the sawmills on the coast.

7. 5. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Hannah Sophie Jakob; [2023]
   Nyckelord :coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

   Sammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER
