  2. 16. Short-range Optical Communications using 4-PAM

    Author : Tamas Lengyel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data communication; vertical cavity surface emitting lasers; 4-PAM; IM DD; NRZ OOK; optical interconnects; short-range fiber optic links; multimode fiber; inter-symbol interference; intensity modulation;

    Abstract : As the demand for ever higher throughput short-range optical links is growing, research and industry has shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying persists to be the choice for low latency applications, such as high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.

  4. 17. A Non-Gaussian Limit Process with Long-Range Dependence

    Author : Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Abstract : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. READ MORE

  6. 19. Range Camera Imaging : From Human Body Measurements to Very Large 3D Points Scenes Visualization

    Author : Gaël Neuez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D visualization; EASYTEX; anatomical landmarks; body scanner; range camera; 2D image projections; structured light; octree data structure;

    Abstract : The use of camera range imaging for the purpose of 3-dimensional representation and non-contact measures is widely used in industry, medicine, computer-aided design and other areas. Different range imaging methods can be applied, such as stereo, laser sheet of light, and structured light. READ MORE

  7. 20. Non-selfadjoint operator functions

    Author : Axel Torshage; Christian Engström; Marco Marletta; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear spectral problem; numerical range; pseudospectrum; resolvent estimate; equivalence after extension; block operator matrices; operator functions; operator pencil; spectral divisor; joint numerical range; Mathematics; matematik;

    Abstract : Spectral properties of linear operators and operator functions can be used to analyze models in nature. When dispersion and damping are taken into account, the dependence of the spectral parameter is in general non-linear and the operators are not selfadjoint. READ MORE
