  1. 1. Gamma Knife treatment planning with new degrees of freedom

    University essay from KTH/Optimeringslära och systemteori

    Author : Emil Norell; [2019]
    Keywords : Stereotactic radiosurgery; Leksell Gamma Knife®; inverse planning; clustering; optimization; column generation; Stereotaktisk radiokirurgi; strålkniven; inversplanering; klustring; optimering; kolumn-generering;

    Abstract : The Leksell Gamma Knife® is an instrument designed for high precision treatment of tumours and lesions located in the brain and upper spine. Today, the radioactive cobalt-60 sources can only move linearly along the radiation unit, but the machine could be modified to include rotational motion as well. READ MORE

  2. 2. Domain similarity metrics for predicting transfer learning performance

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Jesper Bäck; [2019]
    Keywords : nlp.natural language processing; machine learning; transfer learning; similarity metrics; similarity; predict; performance;

    Abstract : The lack of training data is a common problem in machine learning. One solution to thisproblem is to use transfer learning to remove or reduce the requirement of training data.Selecting datasets for transfer learning can be difficult however. READ MORE

  3. 3. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Jan Brabec; [2018]
    Keywords : dMRI; diffusion magnetic resonance; axonal trajectory; axonal geometry; undulations; modeling; axons; inverse problem; diffusion spectrum; time-dependent diffusion; Physics and Astronomy;

    Abstract : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. READ MORE

  4. 4. Multipath TCP and Measuring end-to-end TCP Throughput : Multipath TCP Descriptions and Ways to Improve TCP Performance

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : VEERA VENKATA SIVARAMAKRISHNA BONAM; [2018]
    Keywords : Congestion Control; end-to-end; IP network; TCP performance; Throughput;

    Abstract : Internet applications make use of the services provided by a transport protocol, such as TCP (a reliable, in-order stream protocol). We use this term Transport Service to mean the end-to- end service provided to application by the transport layer. READ MORE

  5. 5. Methods for Automatic Hydraulics Calibration in Construction Equipment

    University essay from Mälardalens högskola/Inbyggda system; Mälardalens högskola/Inbyggda system

    Author : Peter Charbachi; Filippo Ferrario; [2018]
    Keywords : ;

    Abstract : In this thesis we investigate the problem of automatic calibration and control of hydraulic components in the domain of construction equipment. Methods that are able to remove a costly manual approach in favour of an automatic one are investigated and evaluated. READ MORE
