    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Ultrasonic pulse-echo testing; nondestructive testing; maximum a posteriori estimation; linear minimum mean squared error estimation; robust filtering; multivariable filtering; sparse deconvolution; Materialvetenskap; Materials science; Teknisk materialvetenskap; Signal Processing; signalbehandling;

    Sammanfattning : In the thesis, various aspects of deconvolution of ultrasonic pulse-echo signals in nondestructive testing are treated. The deconvolution problem is formulated as estimation of a reflection sequence which is the impulse characteristic of the inspected object and the estimation is performed using either maximum a posteriori (MAP) or linear minimum mean square error (MMSE) estimators.

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; the body; embodiment; existence; suffering; forms of knowledge; essentialism; constructionism; practice; transcendence; immanence; Sociologi; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : We could all be said to be the body in different ways. The premise of this thesis is that our conventional manner of being the body is problematic and generates suffering. The main aim of the thesis is in short to describe the conventional manner and notion of being the body and investigate what options there are. LÄS MER

  4. 3. Heart failure in elderly with focus on diagnosis and prognosis

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elderly; chronic heart failure; primary health care; natriuretic peptides; prognosis; mortality; hospitalisation;

    Sammanfattning : Background: Patients older than 75 years with heart failure (HF) are at increased risk for mortality and hospital admissions. Echocardiography and brain natriuretic peptides (BNP, NTproBNP) are important diagnostic tools but sparsely evaluated in elderly PHC patients. LÄS MER

  5. 4. Change Point Detection with Applications to Wireless Sensor Networks

    Författare :Markus Eriksson; Tomas Olofsson; Idris Eckley; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change Point Detection; Signal Processing; Dynamic Programming; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : In this thesis work we develop a new algorithm for detecting joint changes in statistical behavior of multiple, simultaneously recorded, signals. Such signal analysis is commonly known as multivariate change point (CP) detection (CPD) and is of interest in many scientific and engineering applications. LÄS MER

  7. 5. Det beslöjade rummet : Ideologiska samhällsbilder i grundskolans samhällskunskap

    Sammanfattning : A veiled space - Ideological Images of Society in Swedish Compulsory School CivicsLars Sandin This study deals with the ideological dimension of education in the Swedish compulsory school [grundskolan]. By focusing on the images of the social world which are configured in the content of education, the study pays attention to the reproduction of an ideological dimension which is latent in our social imaginary.
