  2. 1. Being in balance or stuck in time : exploring facets of time processing in relation to mental health

    Author : Elisabeth Åström; Maria Grazia Carelli; Britt Wiberg; Marc Wittmann; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Time perspective; Time estimation; Anxiety; Anxiety disorder; Balanced time perspective; Mental health; Subjective well-being; Clinical Psychology; klinisk psykologi;

    Abstract : Time is central in human functioning and crucial for adaptive behavior. The aim of the current thesis was to investigate aspects of people’s subjective experience of time and their relationship with mental health, specifically anxiety and subjective well-being. READ MORE

  4. 2. Probabilistic time estimation in tunnel projects

    Author : Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. READ MORE

  5. 3. On Parameter Estimation : Applications in Radio Astronomy and Power Networks

    Author : Jonas Lundbäck; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; Antenna arrays; FMCW-radar; Polarization estimation; Fault locator;

    Abstract : Signal processing is a common part of the modern society used to obtain high functionality in a vast number of applications. As the development of advanced electronics and powerful computers continue, the limit of the functionality in many systems is increased. READ MORE

  6. 4. Estimation and Classification of Non-Stationary Processes : Applications in Time-Frequency Analysis

    Author : Johan Brynolfsson; Statistical Signal Processing Group; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time-Frequency Estimation; Parameter Estimation; Reassignment method; Non-Stationary Processes; Smooth spectral estimation; Neural Networks;

    Abstract : This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated. READ MORE

  7. 5. Power System Oscillations - Detection, Estimation and Control

    Author : Morten Hemmingsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. READ MORE
