  1. 11. 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

  3. 12. Customer-focused data-driven target setting

    Författare :Anna Marti Bigorra; Ove Isaksson; Magnus Karlberg; Jan-Olov Aidanpää; Dag Henrik Bergsjö; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : To develop products through a customer-centric strategy, early stages of product development such as target setting play an important role. In the target setting stage Customer Needs (CN) are gathered and translated into Design Requirements (DR) in order to subsequently set product targets that fit cost constraints and at the same time result in high Customer Satisfaction (CS).

  4. 13. About Physical Human Robotic Interaction for Assistive Exoskeletons

    Författare :Nauman Masud; Magnus Isaksson; Christian Smith; Shaoping Bai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

    Sammanfattning : The thesis work has contributed to the field of assistive robotics. The physical interaction between the exoskeleton and human has been studied by considering performance both at the joint as well as task space level of the exoskeleton. LÄS MER

  5. 14. Digital Compensation Techniques for Transmitters inWireless Communications Networks

    Författare :Efrain Zenteno; Peter Händel; Magnus Isaksson; Thomas Brazil; KTH; []
