  1. 16. Interactive RFID for Industrial and Healthcare Applications

    Författare :Jue Shen; Lirong Zheng; Hannu Tenhunen; Bengt Oelmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radio-Frequency Identification RFID ; Electrochromic EC display; energy harvesting; Ultra-Wideband UWB ; remote monitoring; Internet-of-Things IoT .;

    Sammanfattning : This thesis introduces the circuit and system design of interactive Radio-Frequency Identification (RFID) for Internet of Things (IoT) applications. IoT has the vision of connectivity for anything, at anytime and anywhere. LÄS MER

  3. 17. Use of remote sensing and in situ observations of the atmosphere in chemical transport models

    Författare :Emma Ward; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate; Air quality; Ground based observations; Satellite observations; Chemical transport modelling;

    Sammanfattning : Measuring and simulating atmospheric chemical compositions helps us to better understand the impact from long-range transport of different pollutants. Aerosols and tropospheric ozone are examples of pollutants with life times long enough to get transported between continents. LÄS MER

  4. 18. Spatio-temporal filtering of ultrasound image sequences

    Författare :Nina Eriksson-Bylund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A number of diseases result in reduced perfusion of the vital organs of the body. Measures of the blood flow in the small vessels (the perfusion) of these organs would contribute significantly to a clinical diagnosis. Myocardial contrast echocardiography is a rapidly developing technique for non-invasive ultrasound imaging of perfusion. LÄS MER

  5. 19. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    Författare :Klas Folkesson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

    Sammanfattning : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  7. 20. Quantum transport and spin effects in lateral semiconductor nanostructures and graphene

    Författare :Martin Evaldsson; Igor Zozoulenko; Vidar Gudmundsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electronic transport; Spin related phenomena; Quantum dots; Quantum wires; Two-dimensional electron gas; 2DEG; Graphene; Computational physics; Beräkningsfysik; Physics; Fysik;

    Sammanfattning : This thesis studies electron spin phenomena in lateral semi-conductor quantum dots/anti-dots and electron conductance in graphene nanoribbons by numerical modelling. In paper I we have investigated spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. LÄS MER
