  1. 21. Modeling and Design of Modular Multilevel Converters for Grid Applications

    Författare :Kalle Ilves; Hans-Peter Nee; Rainer Marquardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular multilevel converter; feed-forward control; modulation; switching frequency; energy storage;

    Sammanfattning : This thesis aims to bring clarity to the dimensioning aspects and limiting factors of the modular multilevel converter (MMC). Special consideration is given to the dc capacitors in the submodules as they are a driving factor for the size and weight of the converter. LÄS MER

  3. 22. Aircraft conceptual design methods

    Författare :Patrick Berry; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Generally aircraft conceptual design is defined as the starting point for concept sketcing and evaluation, but before that work can start an even earlier stage has to be covered.This is the stage where different scenarios are being worked through in which the aircraft as a platform is supposed to work.

  4. 23. Thin-walled steel studs in fire : analysis and design recommendations

    Författare :Peter Karlström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Development of steel frame modular buildings is gaining increased popularity and support throughout Europe. Due to flexibility in construction and good long-term performance, lightweight steel frame structures are often preferred solutions, for instance in partitions and suspended ceilings as well as for load-bearing elements.

  5. 24. Decentralized Modular Router Architectures

    Författare :Markus Hidell; Gunnar Karlsson; Peter Sjödin; Gísli Hjálmtýsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet; Router architectures; Communication systems; Distributed systems; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet grows extremely fast in terms of number of users and traffic volume, as well as in the number of services that must be supported. This development results in new requirements on routers—the main building blocks of the Internet. LÄS MER

  7. 25. Procedure-Modular Verification of Temporal Safety Properties

    Författare :Siavash Soleimanifard; Dilian Gurov; Gerardo Schneider; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modular Verification; Compositional Verification; Maximal Models; Model Checking; Temporal Properties;

    Sammanfattning : This thesis presents a fully automated technique for procedure-modular verification of control flow temporal safety properties. Procedure-modular verification is a natural instantiation of modular verification where modularity is achieved at the level of procedures. LÄS MER
