  1. 1. Two-Barrier Problems in Applied Probability: Algorithms and Analysis

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Mats Pihlsgård; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; programming; actuarial mathematics; Statistik; Matematik; Mathematics; Naturvetenskap; Natural science; Reflection; Stochastic processes; Applied probability; Queueing; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x<n$ to reach level $n$. We use two different techniques. READ MORE

    Author : Anton Grafström; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conditional Poisson sampling; correlated Poisson sampling; entropy; extended Sampford sampling; Horvitz-Thompson estimator; inclusion probabilities; list-sequential sampling; non-rejective implementation; Pareto sampling; Poisson sampling; probability functions; ratio estimator; real-time sampling; repeated Poisson sampling; Sampford sampling; sampling designs; splitting method; unequal probability sampling; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : The main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. When the units in the population do not have the same probability of being included in a sample, it is called unequal probability sampling. READ MORE

  3. 3. System identification of large-scale linear and nonlinear structural dynamicmodels

    University dissertation from Chalmers University of Technology

    Author : Vahid Yaghoubi; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Uncertainty quantification; Bootstrapping; Polynomial chaos expansion; Surrogate modeling; Exponential integration; Finite element model;

    Abstract : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. READ MORE

  4. 4. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

    University dissertation from Chalmers University of Technology

    Author : Azra Habibovic; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Matematisk statistik; Mathematical statistics; Kognitionsforskning; Cognitive science; Övrig elektroteknik; elektronik och fotonik; Other electrical engineering; electronics and photonics; Systemteknik; Systems engineering; Vulnerable road user VRU ; Causation analysis; Statistical analysis; Naturalistic observation; Driver behavior; VRU behavior; Functional requirements; Accident prevention; Active safety system;

    Abstract : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.

  5. 5. Aggregating Case Studies of Vehicle Crashes by Means of Causation Charts: An Evaluation and Revision of the Driving Reliability and Error Analysis Method

    University dissertation from Chalmers University of Technology

    Author : Jesper Sandin; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Matematisk statistik; Mathematical statistics; Kognitionsforskning; Cognitive science; Övrig teknisk mekanik; Other engineering mechanics; driver error; collision avoidance; pre-crash; fatigue; slipperiness; rollover; young drivers; vehicle dynamics;

    Abstract : There is a need for increased knowledge about causes of motor-vehicle crashes and their prevention. Multidisciplinary in-depth case studies can provide detailed causation data that is otherwise unattainable. Such data might allow the formulation of hypotheses of causes and causal relationships for further study. READ MORE
