    Author : Gill Sörensen Duppils; Karin Wikblad; Sjödén Per-Olov; Astrid Norberg; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

    Abstract : 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).

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

    Author : Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  3. 3. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models

    Author : Nasser Mohammadiha; Arne Leijon; W. Bastiaan Kleijn; Cédric Févotte; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  4. 4. Model Selection and Sparse Modeling

    Author : Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

  5. 5. Post-operative delirium after elective cardiac surgery : Risk factors and cognitive long-term outcome. Results from a clinical study

    Author : Graciela Veliz Reissmüller; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; CAM; cardiac surgery; cognition; delirium; MMSE;

    Abstract : Delirium is a serious problem in the older patient. Delirium is associated with a significant independent morbidity and mortality that increases hospital costs. Due to the increasing elderly population, delirium is becoming an important problem in the western countries. READ MORE
