1. 1. Modelling and Quality Assessment of Atrial Fibrillatory Waves

   Författare :Mikael Henriksson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECG; signal processing; atrial fibrillation; signal quality; catheter ablation; atrial fibrillatory waves; f-waves;

   Sammanfattning : This doctoral thesis revolves around the analysis of electrocardiogram (ECG) signals during atrial fibrillation (AF). Special emphasis is put on the atrial fibrillatory waves, sometimes called the f-waves, which is the ECG component reflecting the electrical activity of the atria. LÄS MER

   Sammanfattning : The combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle manipulation systems can be used e.g. LÄS MER

4. 3. Development of Protein Microarray Chip Technology: An Outlook towards Proteomics and Diagnostics

   Författare :Anton Ressine; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; Teknik; Technological sciences; Naturvetenskap; Natural science; Diagnostik; Diagnostics; Medicin människa och djur ; Medicine human and vertebrates ; Biomedicinska vetenskaper; Biomedical sciences; water repellency; superhydrophobicity; proteolitic digestion; MALDI-TOF MS; bioassay; porous silicon; biomarker; diagnostics; protein microarrays; proteomics;

   Sammanfattning : One attractive method for monitoring biomolecular interactions in a highly parallel fashion is the use of microarrays. Microarrays can be applied for screening proteins which makes it an attractive tool in clinical diagnostics, drug discovery studies and basic protein research; even though many methodological challenges and ones relating to the quality control of microarrays still need to be solved.

5. 4. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

   Författare :Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

   Sammanfattning : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

7. 5. On chip integrated sample preparation for proteomics

   Författare :Simon Ekström; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; enzymologi; Proteiner; enzymology; Proteins; Analytisk kemi; sample preparation; mass spectrometry; microfluidics; miniaturization; Biochemical technology; proteomics; Analytical chemistry; Biokemisk teknik;

   Sammanfattning : The aim of this thesis project has been to create miniaturized analytical tools that improve sample preparation for the very rapidly growing field of proteomics research. The presented miniaturized analytical tools provide novel and generic analytical solutions, which are highly adaptable for analysis of various low abundant biomolecules. LÄS MER
