  1. 16. Sample and hold measurement for binary detection of a quantum state

    Author : Jochen Walter; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics Other physics; NATURVETENSKAP Fysik Övrig fysik;

    Abstract : Measuring the dynamics of a quantum bit (qubit) relies on the accurate detection of the quantum state of the system. A widely used method to measure the state of a solid state Josephson junction qubit is to measure the switching current of a Josephson device. READ MORE

  2. 17. Signal Shaping and Sampling-based Measurement Techniques for Improved Radio Frequency Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Charles Nader; KTH.; KTH.; Högskolan i Gävle.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Trådlösa kommunikationssystem förekommer överallt i vår vardag, med höga förväntningar på kapacitet, tillförlitlighet och energieffektivitet. För att uppfylla förväntningar på kapacitet och tillförlitlighet är dagens trådlösa system utrustade med avancerade modulationsmetoder, såsom Orthogonal Frequency Division Multiplexing (OFDM), vilket medför att dagens trådlösa signaler har stora bandbredder och höga toppfaktorer.

  3. 18. Local Polynomial Regression with Application on Lidar Measurements

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Torgny Lindström; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; differential equations; Funktioner; differentialekvationer; variance-function estimation.; spatial dependence; nonparametric; local polynomial regression; local bandwidth selection; lidar; heteroscedasticity; Bivariate estimation; differential absorption; Functions;

    Abstract : This thesis deals with the problem of estimating a function or one of its derivatives from a set of measurements, mainly of a bivariate or spatial nature which is so common in environmental applications. In this work particular attention has been on the lidar (light detection and ranging) application which is a versatile technique for measurement of among other things atmospheric trace gases.

  4. 19. Model-Based Analysis of Critical Resources in Automotive System Architectures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kenneth Lind; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture analysis; software component; Functional Size Measurement; System architecture; quality attribute; automotive.; architecture evaluation;

    Abstract : Modern cars contain more and more innovative user functions, some of which can only be implemented in software and electronics. Electronics and software allows the vehicle system to be flexible, and at the same time creates additional complexity. READ MORE
