    Författare :Ingrid Öberg Månsson; Mahiar Hamedi; Lars Wågberg; Gaston A. Crespo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Textile; e-textiles; textile-based diagnostics; microfluidics; glucose sensing; sweat based diagnostics; wearable sensors; micro total analysis systems μTAS ; electrochemistry and organic electrochemical transistor OECT ; Fiber- och polymervetenskap; Fibre and Polymer Science; Teknisk materialvetenskap; Materials Science and Engineering; Bioteknologi; Biotechnology;

    Sammanfattning : This thesis, written by Ingrid Öberg Månsson at KTH Royal Institute of Technology and entitled “Electroanalytical devices with fluidic control using textile materials and methods”, presents experimental studies on the development of textile based electronic devices and biosensors. One of the reasons why this is of interest is the growing demand for integrated smart products for wearable health monitoring or energy harvesting. LÄS MER

  3. 7. Architecting Safe Automated Driving with Legacy Platforms

    Författare :Naveen Mohan; Martin Törngren; Jakob Axelsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architectures; automated driving; autonomous vehicles; methods; processes; tools; functional safety; ISO 26262; diagnostic specifications; platform based design; legacy integration; functional safety concept; preliminary architectural assumptions; uncertainty management; design decisions;

    Sammanfattning : Modern vehicles have electrical architectures whose complexity grows year after year due to feature growth corresponding to customer expectations. The latest of the expectations, automation of the dynamic driving task however, is poised to bring about some of the largest changes seen so far. LÄS MER

  4. 8. Non-invasive diagnostic methods of intracranial arteries

    Författare :Birgitta Ramgren; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracranial aneurysms; endovascular treatment; follow-up; subarachnoid haemorrhage; digital subtraction angiography; magnetic resonance angiography; computed tomography angiography; technical aspects; contrast agents; image quality;

    Sammanfattning : Aims of this thesis were to compare the agreement of different magnetic resonance angiography(MRA) techniques and digital subtraction angiography (DSA) in follow-up of intracranial aneurysms treated with coils in order to select the best MRA method, to evaluate the impact of increased iodine concentration in contrast medium and decreased tube voltage on arterial attenuation and image quality in computed tomography angiography (CTA) of intracranial arteries, and finally to evaluate the diagnostic accuracy of CTA in non-traumatic subarachnoid haemorrhage (SAH) compared to DSA and to assess the arterial attenuation (HU) as an image quality factor in this aspect. Follow-up DSA and time-of-flight (TOF) MRA at 1. LÄS MER

  5. 9. An electrostatic sampling device for point-of-care detection of bioaerosols

    Författare :Laila Ladhani; Wouter van der Wijngaart; Jorma Keskinen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrostatic sampling; bioaerosols; point-of-care; breath sampling; electrostatic precipitation; microfluidic collection; corona discharge; air sampling; non-invasive diagnostics; exhaled breath analysis; on-site detection; aerosol sampling; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Bioaerosols are not only a significant factor of air quality but contribute greatly to the spread of infectious diseases, specifically through expired pathogen-laden aerosols. Clear examples of airborne transmission include: the recent influenza pandemic of 2009, the ongoing tuberculosis epidemic, and yearly norovirus out- breaks, which affect millions of people worldwide and pose serious threats to public healthcare systems.
