  2. 21. Design of High Linearity MMIC Power Amplifiers for Space Applications

    Author : Oliver Silva Barrera; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pHEMT; GaAs; reliability; Power amplifier; non-linear modeling; Junction temperature; C-Band; Infrared measurements;

    Abstract : The high linearity performance in satellite transmitters is receiving increasing attention due to the demands of higher data rates in satellite communication links. During the last decade, digital communication links in satellite system have been replacing the previous analog links increasing the channel efficiency by allocating multiple carriers in the transponder bandwidth.

  4. 22. Risk-based methods for reliability investments in electric power distribution systems

    Author : Karin Alvehag; Lennart Söder; Kjølle Gerd; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distribution system reliability; risk management; quality regulation design; customer interruption costs; weather modeling; Monte Carlo simulations; Electric power engineering; Elkraftteknik;

    Abstract : Society relies more and more on a continuous supply of electricity. However, while underinvestments in reliability lead to an unacceptable number of power interruptions, overinvestments result in too high costs for society. READ MORE

  5. 23. Reliability analysis and cost modeling of degrading systems

    Author : Saurabh Kumar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Degradation is an on-going process in systems, equipments and components subjected to various stresses and adverse operating conditions. The factors influencing the degradation process may adversely affect the system or component performance. READ MORE

  6. 24. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods

    Author : Fredrik Jonsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; methyl chloride; dichloromethane; toluene; styrene; uncertainty; intra- individual variability; risk assessment; physiologically based modeling; Markov chain Monte Carlo; PBPK; Bayesian; population modeling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. READ MORE

  7. 25. Statistical Data Analysis for Internet-of-Things : Scalability, Reliability, and Robustness

    Author : Xiuming Liu; Edith Ngai; Dave Zachariah; Bengt Jonsson; Tobias Oechtering; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Internet-of-Things is a set of sensing, communication, and computation technologies to connect physical objects, such as wearable devices, vehicles, and buildings. From those connected “Things”, a large amount of data is generated. READ MORE
