      Birkett, Max; Savory, Christopher N; Rajpalke, Mohana; Linhart, Wojciech M; Whittles, Thomas J; Gibbon, James T; Welch, Adam W; Mitrovic, Ivona Z.; Zakutayev, Andriy; Scanlon, David; Veal, Tim D (Journal article; Peer reviewed, 2018)
      The temperature-dependence of the band gap of the proposed photovoltaic absorber copper antimony sulphide (CuSbS2) has been studied by Fourier-transform infrared spectroscopy. The direct gap rises from 1.608 to 1.694 eV ...
    • Bandwidth Extension of Telephony Speech 

      Johansen, Martin Etnestad (Master thesis, 2009)
      The public switched telephone network (PSTN) restricts the acoustic bandwidth of telephonyspeech to less than 4 kHz. For compatibility with analog telephone networks, a 0.3 − 3.4 kHz passband is common. This bandwidth ...

    • Battery-free Wireless Communication for Video Capsule Endoscopy 

      Noormohammadi, Reza; Khaleghi, Ali; Balasingham, Ilangko (Peer reviewed; Journal article, 2019)
      Wireless capsule endoscopy is an advanced application of using ICT in healthcare and medicine. It is a non-invasive method to examine the gastrointestinal (GI) for early diagnosis and treatment. The capsule is equipped ...
    • Bayesian Fault Detection and Localization Through Wireless Sensor Networks in Industrial Plants 

      Tabella, Gianluca; Ciuonzo, Domenico; Paltrinieri, Nicola; Salvo Rossi, Pierluigi (Peer reviewed; Journal article, 2024)
      This work proposes a data fusion approach for quickest fault detection and localization within industrial plants via wireless sensor networks. Two approaches are proposed, each exploiting different network architectures. ...
    • Bayesian range estimate from two-directional phase measurements 

      Forbord, Jenny Aune. (Master thesis, 2023)
      Teknologien utvider seg stadig, og i dag kan man finne elektronikk og programvare i mange ulike gjenstander. Å kunne bestemme posisjonen til en gjenstand er i mange sammenhenger ønskelig. Det finnes flere gode posisjonsløsninger ...
    • Behandling av inkontinens med magneter 

      Landro, Harald (Master thesis, 2013)
      I fattige land hender det at kvinner mister all kontroll over urinblæra etter kompliserte fødsler. Denne oppgaven har undersøkt et mulig hjelpemiddel for disse kvinnene basert på å ha en plugg i urinblæra som styres av en ...
    • Behavioral Modelling and Design of Noise Shaping SAR ADC in 22nm FDSOI 

      Balasubramanian, Shankkar (Master thesis, 2019)
      Successive Approximation Registers(SAR) Analog to Digital Converters(ADCs) are very power efficient for Effective Number Of Bits(ENOB) below 9 bits. Above 9 bits, low noise comparator current could potentially limit the ...
    • Benefiting From State Dependencies in Asymmetric SRAM Cells Through Conditional Word-Flipping 

      Låte, Even; Ytterdal, Trond; Aunet, Snorre (Peer reviewed; Journal article, 2020)
