  1. 26. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

    Författare :Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
    Nyckelord :Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. LÄS MER

  3. 27. Going digital : Business model innovation in omni-channel retailing

    Författare :Milan Jocevski; Niklas Arvidsson; Antonio Ghezzi; Maxim Miterev; Hannu Saarijärvi; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell ekonomi och organisation; Industrial Economics and Management;

    Sammanfattning : Over the last ten years, digital technologies have had immense effect on the way we live and work, on organizational forms, and on industrial trends. These effects have not left retail industries and their various actors untouched, but have rather forced them to adapt to the changing environment. LÄS MER

  4. 28. Security in Embedded Systems : A Model-Based Approach with Risk Metrics

    Författare :Maria Vasilevskaya; Simin Nadjm-Tehrani; Ketil Stølen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The increasing prevalence of embedded devices and a boost in sophisticated attacks against them make embedded system security an intricate and pressing issue. New approaches to support the development of security-enhanced systems need to be explored. LÄS MER

  5. 29. Model Checking Methods for Mode Switching Systems

    Författare :Valur Einarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with modeling and analysis of a special class of hybrid systems, i.e., systems displaying behavior of both continuous and discrete nature. LÄS MER

  7. 30. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method

    Författare :Jörgen Stenarson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extraction; S-parameter; noise parameter; vector network analyzer; electro-magnetic probe; microwave; non-contacting testing; transistor noise model; VNA; EM-probe; non-invasive testing;

    Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER
