  1. 1. Bilinear Regression and Second Order Calibration

    University dissertation from Stockholm : Stockholm University

    Author : Marie Linder; Stockholms universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemometrics; calibration; multivariate; hyphenated methods; matrix data; bilinear model; least squares; singular value decomposition; generalized rank annihilation; trilinear decomposition; parallel factor analysis; principal components regression; partial least squares; prediction; matematisk statistik; Mathematical Statistics;

    Abstract : We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. READ MORE

  2. 2. The Apparent Arbitrariness of Second-Order Probability Distributions

    University dissertation from Stockholm : Department of Computer and Systems Sciences, Stockholm University

    Author : David Sundgren; Högskolan i Gävle.; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Adekvat representation av osäkra eller imprecisa sannolikheter är ett avgörande och icke-trivialt problem i beslutsanalys. I denna avhandling diskuteras förtjänsterna hos andra ordningens sannolikheter som en modell för imprecisa sannolikeheter. READ MORE

  3. 3. Spectrum Sensing Algorithms Based on Second-Order Statistics

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Erik Axell; Linköpings universitet.; Linköpings universitet.; [2012]

    Abstract : Cognitive radio is a new concept of reusing spectrum in an opportunistic manner. Cognitive radio is motivated by recent measurements of spectrum utilization, showing unused resources in frequency, time and space. Introducing cognitive radios in a primary network inevitably creates increased interference to the primary users. READ MORE

  4. 4. Investigations intothe crystallization of butyl paraben

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Huaiyu Yang; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Butyl paraben; Solubility; Thermodynamic; Activity; Activity coefficient; Second order correlation; Liquid-liquid phase separation; Ternary phase diagram; Nucleation; Induction time; Free energy; Interfacial energy; Nuclei critical radius Cooling crystallization; Evaporation crystallization; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : In thisproject, solubility of butyl paraben in 7 puresolvents and 5 ethanol aqueous solvents has been determined at from 1 ℃to 50 ℃. Thermodynamic properties of butyl paraben have been measured by DifferentialScanning Calorimetey. READ MORE

  5. 5. Multiconfigurational perturbation theory

    University dissertation from Lund

    Author : Kerstin Andersson; Karlstads universitet.; Karlstads universitet.; [1992]
    Keywords : Electron correlation; CASSCF; multiconfigurational second-order perturbation theory; CASPT2; ozone; C; N; O; F; Si; P; S; Cl; Ni; benzene; pyridine; pyrazine; pyrimidine; pyridazine; s-triazine; electric properties; excited states; spectroscopic data;

    Abstract : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. READ MORE
