  1. 1. Integration of Planar Antennas with MMIC Active Frontends for THz Imaging Applications

    Author : Yogesh Karandikar; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sub-Harmonic Resistive Mixer; Planar Antennas; Gaussian Coupling; MMIC; Gilbert Cell Mixer; THz;

    Abstract : In recent years, there has been constant growth in using THz frequencies or mm, sub- mm wavelengths for various applications such as: Astronomy, Atmospheric studies, security, bio-medical imaging. All these applications are now seen more feasible due to rapid enhancements of semi-conductor processing technologies. READ MORE

  2. 2. Stochastic Resonance and Noise-Assisted Signal Transfer : On Coupling Effects of Stochastic Resonators and Spectral Optimization of Fluctuations in Random Network Switches

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter Hammerstein; Uppsala universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; stochastic resonance; nonlinear stochastic dynamics; noise and fluctuations; magnetic domains; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Abstract : Recent research shows that noise or random fluctuations must not always be destructive in Nature by degrading system performance. On the contrary, in nonlinear systems they can synchronize systems or enhance the quality of signal transmission. The latter possibility is reported in the thesis. READ MORE

  3. 3. Approximation of Infinitely Divisible Random Variables with Application to the Simulation of Stochastic Processes

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Magnus Wiktorsson; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; aktuariematematik; Stochastic differential equation; Infinitely divisible distribution; Type G distribution; Lévy process; Stochastic integral; Mathematical Statistics; Matematik; Mathematics; programming; actuarial mathematics; Statistik; operationsanalys; programmering;

    Abstract : This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. READ MORE

  4. 4. On two-dimensional conformal geometry related to the Schramm-Loewner evolution

    University dissertation from Stockholm, Sweden. : KTH Royal Institute of Technology

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conformal invariance; scaling; random fractals; Matematik; Mathematics;

    Abstract : This thesis contains three papers, one introductory chapter and one chapter with overviews of the papers and some additional results. The topic of this thesis is the geometry of models related to the Schramm-Loewner evolution. READ MORE

  5. 5. Modelling and Control Methods with Applications to Mechanical Waves

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hans Norlander; Uppsala universitet.; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Abstract : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.
