  1. 6. Hidden Markov models : Identification, control and inverse filtering

    Författare :Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

  2. 7. Input Estimation in Structural Dynamics

    Författare :Lars Nordström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; dynamic programming; input estimation; load identification; ill-posedness; regularization; indirect force measurement; inverse problems;

    Sammanfattning : Knowledge of time-varying excitation is of importance in the design of a wide range of engineering applications, from spacecraft and processing plants to electronic circuits. Regardless of the actual application or underlying physics, the expected input will play a key role in the determination of adequate system properties and parameters. LÄS MER

  3. 8. Modeling and Control of Flexible Manipulators

    Författare :Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

    Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. LÄS MER

  4. 9. Estimating Effective Interactions from Particle Trajectories

    Författare :Kolbjörn Tunström; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 10. Entrepreneurial Dynamics and Acquisitions of New Technology-Based Firms

    Författare :Jing Xiao; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business groups; New technology-based firms NTBFs ; Acquisitions; Entrepreneurial dynamics; Acquisition effects; Survival; Firm growth; Business cycle; Multinational enterprises MNEs ; Longitudinal data; Discrete-time duration models; Competition risks models; Fixed effects model; Inverse-probability-of-treatment weights IPTW ; Sweden;

    Sammanfattning : The aim of this thesis is to explore the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. NTBFs are argued to be one important type of entrepreneurial firms that contribute to technology change, knowledge spillovers, and economic growth. LÄS MER
