1. 1. Ruin probabilities and first passage times for self-similar processes

   Författare :Zbigniew Michna; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Simulation of Ruin Probability; Monte Carlo Method; Skorokhod Topology; Weak Convergence; Rice s Formula; Fluid Model; Risk Model; Scaled Brownian Motion; Long Range Dependence; Fractional Brownian Motion; Renewal Process; Levy Motion; Stable Process; Self-Similar Process; Gaussian Process; Ruin Probability; First Passage Time; Exponential Bound; Picands Constant.; Mathematics; Matematik;

   Sammanfattning : This thesis investigates ruin probabilities and first passage times for self-similar processes. We propose self-similar processes as a risk model with claims appearing in good and bad periods. Then, in particular, we get the fractional Brownian motion with drift as a limit risk process.

   Sammanfattning : Introduction: Neck pain is a common problem in society and is more prevalent among women. The consequences of neck pain for the individual often include activity and participation limitations, thus affecting many dimensions of life. LÄS MER

5. 4. A Non-Gaussian Limit Process with Long-Range Dependence

   Författare :Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

   Sammanfattning : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. LÄS MER

7. 5. Safe data-driven control for robots with constrained motion

   Författare :Pouria Tajvar; Jana Tumova; Ram Vasudevan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven control; System abstraction; Motion planning;

   Sammanfattning : Widespread deployment of robots in offices, hospitals, and homes is a highly anticipated breakthrough in robotics. In such environments, the robots are expected to fulfil new tasks as they arrive in contrast to repetitive tasks. Such environments are unstructured and may impose various constraints on a robot's motion. LÄS MER
