  4. 17. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels

    Author : Naga Vishnukanth Irukulapati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viterbi algorithm; fiber-optic channel; stochastic digital backpropagation; performance limits; factor graphs; near-MAP detector; Digital backpropagation; nonlinear compensation; mutual information;

    Abstract : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. READ MORE

  5. 18. Characterisation of the Neutron Wall and of Neutron Interactions in Germanium-Detector Systems

    Author : Joa Ljungvall; Johan Nyberg; Andres Gadea; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; High-purity Ge detectors; Liquid scintillator detectors; Neutron scattering; Digital electronics; Time-of-flight technique; Pulse-shape simulation and analysis; Monte Carlo simulations; Geant4; Gamma-ray tracking; AGATA; Neutron Wall; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : A Monte Carlo simulation of the Neutron Wall detector system has been performed using Geant4, in order to define optimum conditions for the detection and identification of multiple neutrons. Emphasis was put on studying the scattering of neutrons between different detectors, which is the main source of the apparent increase of the number of detected neutrons. READ MORE

  6. 19. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Author : Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. READ MORE

  7. 20. Servicescape for Digital Wellness Services for Young Elderly

    Author : Hans Allmér; Christer Carlsson; Pirkko Walden; Anna Sell; Leif Marcusson; Siw Lundqvist; Anna Ståhlbröst; Finland Åbo Akademi University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informatik; Information Systems; Marketing; Marknadsföring;

    Abstract : In this thesis digital wellness services (DWSs) are in focus. The DWSs are services provided through digital devices, such as smartphones, bracelets, and tablets, by using digital environments such as Internet, cloud services, and websites. READ MORE
