  1. 16. Model-checking and Model-based Testing of Automotive Embedded Systems : Starting from the System Architecture

    Författare :Raluca Marinescu; Cristina Seceleanu; Bernhard Aichernig; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Nowadays, modern vehicles are equipped with electrical and electronic systems that implement highly complex functions such as anti-lock braking or cruise control. The use of such embedded systems in the automotive domain requires a revised development process that addresses their particular features. LÄS MER

  3. 17. On Radio Frequency Behavioral Modeling : Measurement Techniques, Devices and Validation Aspects

    Författare :Per N. Landin; Peter Händel; Magnus Isaksson; Wendy Van Moer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

    Sammanfattning : Effektförstärkare för radiofrekvensapplikationer utgör fortfarande ett av de största problemen i trådlösa kommunikationssystem. Detta beror på att dessa förstärkare är ickelinjära, har låg energieffektivitet och ger mycket distortioner. Bättre verktyg för att förstå och korrigera dessa beteenden är nödvändiga. LÄS MER

  4. 18. Digital Predistortion for the Linearization of Power Amplifiers

    Författare :Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavioral model; Volterra series; nonlinear; digital predistortion; Doherty power amplifier; power amplifier; efficiency;

    Sammanfattning : High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. LÄS MER

  5. 19. A behavioral defense against disease

    Författare :Georgia Sarolidou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Animals, including humans, have evolved under the continuous selection pressure posed by pathogens. As a result, we have developed a set of physiological mechanisms to combat pathogens – the immune system. However, engaging the immune system in this battle can be costly, unnecessarily so in cases when pathogens can be avoided. LÄS MER

  7. 20. Linearization of High Efficiency Transmitters for Wireless Communications

    Författare :Haiying Cao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic load modulation; Behavioral model; digital predistortion; I Q imbalance; Volterra series; efficiency; power amplifier; transmitter;

    Sammanfattning : In recent years, reducing energy consumption in wirelesscommunication systems has gained prominence. In order to achieve this energy saving, high power efficiency is necessary for the wireless transmitters used. LÄS MER
