1. 36. Improving assessment of cardiovascular arrhythmic safety of new pharmacologic agents

   Författare :Lars Johannesen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Fourteen drugs have been removed from the market worldwide due to an increased risk of torsade de pointes (TdP), a potentially fatal ventricular arrhythmia. Almost all of the removed drugs that have been linked to an increased risk for TdP have been shown to block the human ether-à-go-go-related gene (hERG) potassium channel. LÄS MER

3. 37. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

   Författare :Edwin Obando; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

   Sammanfattning : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. LÄS MER

4. 38. Textile electrodes for ECG measurements in distributed care, performance and applications

   Författare :Linda Rattfält; Per Ask; Peter Hult; Maria Lindén; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The aim of this thesis work has been to explore textile electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to noise with signal processing techniques. Previous research within the field has shown that acquisition of ECG is possible with textile electrodes, but little attention has been focused on how they function and especially if movements are included in the measurement protocol.

5. 39. Functional organisation and population behaviour of human peripheral nerve fibres : a microneurography study

   Författare :Gung Wu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :human somatosensory system; nerve organisation; peripheral nerve; cutaneous mechanoreceptors; skin innervation; microneurography; microelectrode;

   Sammanfattning : With regard to the intraneural organisation of peripheral nerves findings obtained from previous anatomical and physiological studies appear to be controversial. The conventional concept seems to be that peripheral nerves lack a detailed topographical organisation. LÄS MER

7. 40. Ultra Wideband: Communication and Localization

   Författare :Vijaya Parampalli Yajnanarayana; Peter Händel; Andreas Springer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra Wideband; TOA; Kalman Filter; Localization; Physical Layer Signaling; Location Aware Communication; Compressive Sampling; Sparse Signal Processing; Wireless Sensor Network; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The first part of this thesis develops methods for UWB communication. To meet the stringent regulatory body constraints, the physical layer signaling technique of the UWB transceiver should be optimally designed. LÄS MER
