  2. 2. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

    Author : Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

    Abstract : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). READ MORE

  3. 3. Sea Level Compensation System for Wave Energy Converters

    Author : Valeria Castellucci; Rafael Waters; Ronan Costello; Uppsala universitet; []
    Keywords : Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

  4. 4. Modelling approaches for audio frequency power transformers

    Author : Julius Krah; KTH; []
    Keywords : power transformer; audio frequency; loss; hysteresis; eddy currents; skin effect. Leakage inductance;

    Abstract : The development of HVDC converters, local generation andtractions systems increases the demand for power converters.While a lot of studies have been conducted on the powerelectronics, there are still open questions concerning thecontained power transformer that operates at a few kilohertz.

  5. 5. The role of fault management in the embedded system design

    Author : Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Management; Resilient system; Recovery methodology.; Computer Science; datavetenskap;

    Abstract : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.
