  1. 1. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

    University essay from

    Author : Dennis Lipnicevic; [2022-01-13]
    Keywords : Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

    Abstract : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

  2. 2. Smart Alarm- On the performance characteristics of linear, multi-linear and non-linear tensor models for alarm prediction in multi-sensor data.

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Chandraprakash Sahu; Ahamed Buhari; [2022]
    Keywords : Machine Learning; Tensor Regression; Deep Learning; Multivariate Time Series;

    Abstract : Information and modern computing technology advancements have led to a rise in the importance of maintenance, particularly in areas where a single components failure could have a significant impact on the overall systems performance. Numerous industries, including Alfa Laval, are operating on conditional-based systems that provide warnings only when a machine fails. READ MORE

  3. 3. Convolutions on graphs for learning vehicle crash behaviour

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Daniel Adin; [2021-11-09]
    Keywords : Computer; science; computer science; engineering; graph; convolutions; inite element method; project; thesis;

    Abstract : Convolutional Neural Networks (CNN) have shown successful results in the recent years, especially within the area of image analysis. The idea of learning to predict the result of a crash simulation using machine learning rose from the analogy between images and Finite Element models (FE-models) used in crash simulations.

  4. 4. Bot or Human: Identifying Bot­Generated Clicks Using Machine Learning

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : FILIP BORG; AXEL BROBECK; SAGA KORTESAARI; NERMIN SKENDEROVIC; ARVID SUNDBOM; CHARLES SUNDSTRÖM; [2021-09-14]
    Keywords : ;

    Abstract : “I’m not a robot” is a common CAPTCHA (Completely Automated PublicTuring test to tell Computers and Humans Apart) often shown today uponentering websites. The purpose behind the challenge is to distinguish hu mans from robots, or bots. However, the user experience becomes somewhatintrusive and is not always viable for many websites. READ MORE

  5. 5. Driver Behavior Classification in Electric Vehicles

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : FEDERICA COMUNI; CHRISTOPHER MÉSZÁROS; [2021-07-06]
    Keywords : Aggressive driver behavior; Driver behavior classification; Self-attention; Recurrence plots; active learning; Active deep dropout; Gradual pseudo labeling;

    Abstract : Studies have shown that driving style affects the energy consumption of electric vehicles, with aggressive driving consuming up to 30% more energy than moderate driving. Therefore, modeling of aggressive driving can provide a more precise estimation of the energy consumption and the remaining range of a vehicle. READ MORE
