2. 1. Nonlinear phonocardiographic Signal Processing

   Author : Christer Ahlström; Per Ask; Anders Johansson; Peter Hult; Pablo Laguna; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal analysis methods; computerized cardiac auscultation system; phonocardiographic PCG signal; mitral insufficiency MI ; time- and cost-saving; Medical engineering; Medicinsk teknik;

   Abstract : The aim of this thesis work has been to develop signal analysis methods for a computerized cardiac auscultation system, the intelligent stethoscope. In particular, the work focuses on classification and interpretation of features derived from the phonocardiographic (PCG) signal by using advanced signal processing techniques. READ MORE

4. 2. A Novel Oil-immersed Medium Frequency Transformer for Offshore HVDC Wind Farms

   Author : Mohammad Kharezy; Per Olof Hedekvist; Yuriu Serdyuk; Thomas Hammarström; Karsten Backhaus; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prototype design methodology; finite element analysis; HVDC insulation design; medium frequency transformer; Wind energy; DC-DC power converters;

   Abstract : In this project, a design of an oil type medium frequency transformer for offshore wind farm applications is proposed. The design is intended for applications when series coupling of the output of the DC/DC converters of the wind turbine on their secondary side is done to achieve a cost-effective high voltage solution for collecting energy from offshore wind parks.

5. 3. Communication and Positioning Uncertainties in Cooperative Intelligent Transportation Systems

   Author : Erik M Steinmetz; RISE; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative positioning; resource allocation; cooperative intelligent transportation systems; packet reliability; vehicular communication;

   Abstract : The current road transport system has problems with both safety and efficiency. Future intelligent transportation systems (ITS) are envisioned to alleviate these problems. In particular, cooperative ITS, where vehicles are connected to each other and the cloud, will allow vehicles to collaborate and share both sensor and control information. READ MORE

6. 4. Data Evaluation for an Electronic Nose

   Author : Martin Holmberg; Jan van der Spiegel; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : An electronic nose is a device that tries to perform the same task as the human olfactory system, to be able to discriminate between different odours. In an electronic nose there are currently a number of individual sensors (typically 5-20). The response from a chemical sensor is usually measured as the change of some physical parameter, e.g. READ MORE

7. 5. Liquid Sensing : Development and Characterisation of an Electronic Tongue Based on Electrochemical Methods

   Author : Susanne Holmin; Elena Dominguez; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : A new sensor technology for liquid sensing is reported, i.e. the electronic tongue based on electrochemical methods. Such a system involves the combination of non-selective sensors (metal electrodes) and a signal processing part. READ MORE
