2. 21. Perceptual and Squared Error Aspects in Speech and Audio Coding

   Author : Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; speech coding; audio coding; auditory models; perceptual distortion measures; squared error; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. READ MORE

4. 22. Generalization under Model Mismatch and Distributed Learning

   Author : Martin Hellkvist; Ayca Özcelikkale; Anders Ahlén; Martin Jaggi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Signal processing; Generalization error; Training error; Double-descent; Double descent; Distributed learning; Distributed optimization; Learning over networks; Model mismatch; Model misspecification; Fake features; Missing features; linear regression; regularization; Machine learning; Maskininlärning;

   Abstract : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. READ MORE

5. 23. Node-Level Fault Tolerance for Embedded Real-Time Systems

   Author : Joakim Aidemark; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault injection; error recovery; reliability calculations; time redundancy; real-time kernels; error detection; analytical coverage estimation; distributed real-time systems;

   Abstract : This thesis deals with cost-effective design and validation of fault tolerant distributed real-time systems. Such systems play an increasingly important role in embedded applications such as automotive and aerospace systems. READ MORE

   Abstract : Skrivande och skrivet språk är idag en viktig del av många människors liv, i datorns ordbehandlare, i e-postprogram och i chattkanaler på Internet. Skrivet språk har blivit mer eller mindre en förutsättning för människors dagliga kommunikation. Denna utveckling av samhället leder till ökade behov av att på olika sätt hantera text. READ MORE

7. 25. Biomechanical methods and error analysis related to chronic musculoskeletal pain

   Author : Fredrik Öhberg; Mats Djupsjöbacka; Åke Öberg; Högskolan i Gävle; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical spine; ensemble theory; error analysis; helical axis; kinematics; movement analysis; neural coding; pattern recognition; spike sorting; whiplash; Medical technology; Medicinsk teknik;

   Abstract : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. READ MORE
