    Sammanfattning : Efforts towards standardization of Vehicular Communication Systems (VCSs) have been conclusive on the use of Vehicular Public-Key Infrastructure (VPKI) for the establishment of trust among network participants. Employing VPKI in Vehicular Communication (VC) guarantees the integrity and authenticity of Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs).

    Nyckelord :UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Sammanfattning : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. LÄS MER

  4. 3. Smart and flexible capacitor charger for warm environments

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Tobias Rydberg; [2016]
    Nyckelord :;

    Sammanfattning : A studio camera flash system being developed by Eascal AB needs a capacitor charging power supply (CCPS) that can work in a hot environment without problems and also not emit too much heat itself. The CCPS needs to be able to operate from battery power as well as net power, so called off-line, and to charge a capacitor to between 0-400 V. LÄS MER

  5. 4. High-Speed Hybrid Current mode Sigma-Delta Modulator

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Balakumaar Baskaran; Hari Shankar Elumalai; [2012]
    Nyckelord :Current mode Sigma Delta Modulator; Leslie-Singh Architecture; Switched Current Integrator; Folded Cascode Integrator; Current mode Flash ADC; High Speed Latched Comparator; Cascode Current Mirrors;

    Sammanfattning : The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. LÄS MER

  7. 5. Pedagogical development and technical research in the area of geothermal power production

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Christopher Denbow; [2011]
    Nyckelord :Geothermal; Power; Electricity;

    Sammanfattning : This work describes the types of power plants used for geothermal power generation in the world; the dry steam power plant, the flash steam power plant and the binary cycle power plant. The objective of the MSc work was the development of learning content on the subject of geothermal power generation for the CompEdu platform in the energy department at KTH. LÄS MER
