  2. 1. Knowledge-based speech enhancement

    Author : Sriram Srinivasan; Bastiaan Kleijn; Rainer Martin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; noise reduction; linear predictive coe±cients; autoregressive; codebooks; maximum-likelihood; Bayesian; nonstationary noise; blind source separation.; Telecommunication; Telekommunikation;

    Abstract : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. READ MORE

    Abstract : This thesis consists of six parts in which methods for image analysis and processing are studied. Two-dimensional medical images, image sequences, and three-dimensional image volumes are considered. READ MORE

  5. 3. Unchaining Microservice Chains : Machine Learning Driven Optimization in Cloud Native Systems

    Author : Michel Gokan Khan; Javid Taheri; Andreas Kassler; Stefan Schulte; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud Native Computing; Service Mesh; Performance Modelling; Performance Optimization; Performance Simulation; Machine Learning; Resource Allocation; Computer Science; Datavetenskap;

    Abstract : As the cloud native landscape flourishes, microservices emerge as a central pillar for contemporary software development, enabling agility, resilience, and scalability in modern computing environments. While these modular services promise opportunities, particularly in the transformative ecosystem of 5G and beyond, they also introduce a myriad of complexities. READ MORE

  6. 4. On Reverberation Enhancement in Auditoria

    Author : Peter Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active sound field control; room acoustics; reverberation enhancement; listening tests; subjective effects; sound-reinforcement; feedback systems; feedback control; computer modelling of acoustics in enclosures; modulation; electro acoustics; time-varying filters;

    Abstract : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. READ MORE

  7. 5. Improving disaster response evaluations : Supporting advances in disaster risk management through the enhancement of response evaluation usefulness

    Author : Ralf Josef Johanna Beerens; Avdelningen för Riskhantering och Samhällssäkerhet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crisis; disaster; emergency; disaster risk management DRM ; preparedness; exercise; simulation; response; performance; evaluation; usefullness; design; The Netherlands;

    Abstract : Future disasters or crises are difficult to predict and therefore hard to prepare for. However, while a specific event might not have happened, it can be simulated in an exercise. READ MORE
