1. 1. Simulating Mobility of Large Population using Mobile Application Data

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

   Författare :Mattias Rydström; Diana Salim; [2024-01-23]
   Nyckelord :Human mobility; mobile application data; synthesize activity plans;

   Sammanfattning : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.

3. 2. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Zeyuan Wu; [2024]
   Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

   Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

   Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

   Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

5. 4. Learning a Grasp Prediction Model for Forestry Applications

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Elias Olofsson; [2024]
   Nyckelord :Forwarder; Autonomous grasping; Deep learning; Multibody dynamics; Convolutional neural network;

   Sammanfattning : Since the advent of machine learning and machine vision methods, progress has been made in tackling the long-standing research question of autonomous grasping of arbitrary objects using robotic end-effectors. Building on these efforts, we focus on a subset of the general grasping problem concerning the automation of a forwarder. LÄS MER

7. 5. Challenges for Artificially Intelligent Medical Devices in the Nordics and Suggested Strategies to Respond

   Master-uppsats, Lunds universitet/Innovationsteknik

   Författare :Alva Rampe; Linea Holström; [2024]
   Nyckelord :Artificial Intelligence; Medical Device; HealthTech; Innovation Barriers; Technology and Engineering;

   Sammanfattning : With aging populations, unequal access to care, and shortages of staff, healthcare systems today are facing many challenges. Technology advancements, with artificial intelligence (AI) in particular, have been one of the main drivers of innovation in multiple industries. LÄS MER
