  2. 16. Conformal anomaly detection : Detecting abnormal trajectories in surveillance applications

    Author : Rikard Laxhammar; Göran Falkman; Pontus Svenson; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; conformal prediction; trajectory analysis; video surveillance; maritime surveillance; Technology; Teknik; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

    Abstract : Human operators of modern surveillance systems are confronted with an increasing amount of trajectory data from moving objects, such as people, vehicles, vessels, and aircraft. A large majority of these trajectories reflect routine traffic and are uninteresting. READ MORE

  4. 17. Waves and Trajectories in Quantum Dots

    Author : Tomas Lundberg; Joan Martorell; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with electron transport in low-dimensional semiconductor nanostructures,and in particular, systems with quasi zero-dimensional properties, called quantum dots. These systems are so small that the electron wavelength is comparable to the size of systems, which means that the wave nature of the electrons is of fundamental importance. READ MORE

  5. 18. Care Trajectories in the Oldest Old

    Author : Marie Ernsth Bravell; Bo Malmberg; Kirsten Avlund; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oldest-old; Health; Social network; ADL; Care; Institutionalization; End-of-life;

    Abstract : This thesis demonstrates relations among health, social network, ADL and patterns of care in the oldest old guided by a resource theoretical model. The analyzed data are based on two studies: the Nona study, a longitudinal study of 157 individuals aged 86 to 94 years, and the H70 study, a longitudinal study of 964 individuals aged 70 at baseline.

  6. 19. Estimating Effective Interactions from Particle Trajectories

    Author : Kolbjörn Tunström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

    Abstract : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. READ MORE

  7. 20. How to model temporal changes in epidemiological data : Treatment trajectories in men with prostate cancer

    Author : Eugenio Ventimiglia; Pär Stattin; Paul C. Lambert; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; state transition model; life expectancy; active surveillance; watchful waiting;

    Abstract : Owing to the improvements in detection, diagnostics, and treatment, many men currently diagnosed with prostate cancer (PCa) have a low risk of PCa death. For many men PCa has become a chronic disease with a small risk of progression that remains even decades after date of diag-nosis. READ MORE
