1. 1. Delirium during Hospitalisation : Incidence, Risk Factors, Early Signs and Patients' Experiences of Being Delirious

   Författare :Gill Sörensen Duppils; Karin Wikblad; Sjödén Per-Olov; Astrid Norberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nursing; delirium; Acute confusional state; hip surgery; hip fracture; replacement surgery; cognitive function; MMSE; Follow-up; health-related quality of life; HRQOL; SF-36; Omvårdnad; Nursing; Omvårdnad; omvårdnadsforskning med medicinsk inriktning; Caring Sciences; Delirium i samband med höftfraktur;

   Sammanfattning : Delirium is common among old patients admitted to hospital, but is often a neglected problem in patient care. The principal aim of this thesis was to evaluate aspects of delirium in relation to incidence, risk factors, behavioural changes, cognitive function and health-related quality of life (HRQOL).

3. 2. Optical studies of AlN and GaO based nanostructures using Mueller matrix spectroscopic ellipsometry

   Författare :Samiran Bairagi; Kenneth Järrendahl; Ching-Lien Hsiao; Bruno Gallas; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GLAD; MMSE; PVD; III-nitrides; Oxides; Anisotropy; Bandgap;

   Sammanfattning : This thesis explores the diverse optical properties manifested when light interacts with various materials, with an emphasis on circular polarization- and bandgaprelated phenomena. The studies in this work are centered around Mueller matrix spectroscopic ellipsometry, with the objective of synthesizing and characterizing nanostructured and high-quality thin films to expand our understanding of the optical properties arising from their underlying structure and electronic transitions, respectively.

4. 3. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

   Författare :Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER

5. 4. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models

   Författare :Nasser Mohammadiha; Arne Leijon; W. Bastiaan Kleijn; Cédric Févotte; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech enhancement; noise reduction; nonnegative matrix factorization; hidden Markov model; probabilistic latent component analysis; online dictionary learning; super-Gaussian distribution; MMSE estimator; temporal dependencies; dynamic NMF;

   Sammanfattning : Reducing interference noise in a noisy speech recording has been a challenging task for many years yet has a variety of applications, for example, in handsfree mobile communications, in speech recognition, and in hearing aids. Traditional single-channel noise reduction schemes, such as Wiener filtering, do not work satisfactorily in the presence of non-stationary background noise. LÄS MER

7. 5. Model Selection and Sparse Modeling

   Författare :Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; Signal processing; Signalbehandling;

   Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER
