    Sammanfattning : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. LÄS MER

  2. 2. SiC Readout IC for High Temperature Seismic Sensor System

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Ye Tian; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; bipolar junction transistor BJT ; integrated circuit IC ; sigma-delta Σ∆ ; data conversion; operational amplifier OpAmp ; VBIC; SPICE Gummel-poon; high-temperature; electromechanical; accelerometer; capacitive sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Over the last decade, electronics operating at high temperatures have been increasingly demanded to support in situ sensing applications such as automotive, deep-well drilling and aerospace. However, few of these applications have requirements above 460 °C, as the surface temperature of Venus, which is a specific target for the seismic sensing application in this thesis. LÄS MER

  3. 3. Prostate cancer sensor combining Raman spectroscopy and tactile resonance technology

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Sammanfattning : Prostate cancer (PCa) is the most common cancer type among men in Sweden. The most prevalent curative treatment for PCa is radical prostatectomy (RP), i.e., complete surgical removal of the prostate. LÄS MER

  4. 4. Design and Performance of Diversity based Wireless Interfaces for Sensor Network Nodes

    Detta är en avhandling från Uppsala : Institutionen för teknikvetenskaper

    Författare :Magnus Jobs; Uppsala universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless; Sensor; Network; WSN; Antenna; WISENET; Node; Diversity; Phased Array; Conformal; WBAN; Body Area; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

    Sammanfattning : The main focus of the work presented in this licentiate thesis concerns antenna design, adaptive antenna control and investigation on how the performance of small wireless nodes can be increased by inclusion of multiple antennas. In order to provide an end-user suitable solution for wireless nodes the devices require both small form factor and good performance in order to be competitive on the marked and thus the main part of this thesis focuses on techniques developed to achieve these goals.

    Sammanfattning : Popular Abstract in English A handful of diseases-causing pathogenic microorganisms claim millions of lives worldwide each year, mainly due to limited diagnostic capabilities. The lack of simple, cost-effective, sensitive and rapid on-site diagnostic tools lead to delays in the diagnoses with a subsequent lag in treatment, which in turn can result in serious complications or even loss of lives.
