  1. 11. Model and Dependency Management in Mechatronic Design

    Författare :Ahsan Qamar; Wikander Jan; Carl During; Kristina Shea; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dependency Modeling; Model-Based Systems Engineering MBSE ; Mechatronic Design; Model Integration; Tool Integration; Common Language; Mechatronic Challenges; Domain Specific Language.;

    Sammanfattning : Managing consistency is a major concern in the design of complex engineering systems. At times, inconsistencies may lead to wrong decisions, resulting in design flaws which can compromise safety and cause failures. One cannot forget the 1999 NASA unmanned MARS Climate Orbiter, which was destroyed due to use of inconsistent units by design teams. LÄS MER

  2. 12. Preservation of Extra-Functional Properties in Embedded Systems Development

    Författare :Mehrdad Saadatmand; Mikael Sjödin; Antonio Cicchetti; Vittorio Cortellessa; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Engineering; Embedded Systems; Non-Functional Requirements; Extra-Functional Properties; Model-Driven Development; Trade-off analysis; Computer Science; datavetenskap;

    Sammanfattning : The interaction of embedded systems with their environments and their resource limitations make it important to take into account properties such as timing, security, and resource consumption in designing such systems. These so-called Extra-Functional Properties (EFPs) capture and describe the quality and characteristics of a system, and they need to be taken into account from early phases of development and throughout the system's lifecycle.

  4. 14. Analysis and Design of Low-Phase-Noise Integrated Voltage-Controlled Oscillators for Wide-Band RF Front-Ends

    Författare :Ali Fard; Denny Åberg; John R. Long; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic; Electronics; Elektronik; Elektronik;

    Sammanfattning : The explosive development of wireless communication services creates a demand for more flexible and cost-effective communication systems that offer higher data rates. The obvious trend towards small-size and ultra low power systems, in combination with the ever increasing number of applications integrated in a single portable device, tightens the design constraints at hardware and software level.
