    Sammanfattning : The rapid advances in information and communication technology enable a shift from diverse systems empowered mainly by either hardware or software to cyber-physical systems (CPSs) that are driving Critical infrastructures (CIs), such as energy and manufacturing systems. However, alongside the expected enhancements in efficiency and reliability, the induced connectivity exposes these CIs to cyberattacks exemplified by Stuxnet and WannaCry ransomware cyber incidents.

  3. 2. Electromagnetic characterization of power electronic systems

    Författare :Mathias Enohnyaket; Mats Alaküla; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Propelled by increased global awareness and demand for clean energy systems, there is a growing trend in transportation, utility, industrial, and residential applications towards the utilisation of power electronic systems with enhanced power ow controllability and eciency. Examples of power electronics applications include terminal converters in high-voltage direct Current (HVDC) transmission; exible AC transmission systems (FACTS); and converters to interface alternative energy systems such as wind turbines to the grid, variable-speed motor drives in pump systems, vehicular propulsion systems, air-conditioners, and refrigerators.

  4. 3. Logistics systems for recycling : on the influence of products, structures, relationships and power

    Författare :Maria Huge Brodin; Linköpings universitet; []
    Nyckelord :logistics systems; recycling; products structures; relationships; power; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The environmental trend, and environmental legislation, has during the past decade grown stronger, and with it the focus on environmental issues within many fields of research and practice. This has implications for logistics, and the focus in this dissertation is on the logistics systems that are needed to realise recycling of end-of-life products: logistics systems for recycling (LSRs).

  5. 4. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Författare :Stavros Tzilis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

    Sammanfattning : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.

  7. 5. Design and Identification of Wireless Transmitters for a Low-power and Secure Internet of Things

    Författare :Wenqing Yan; Christian Rohner; Thiemo Voigt; Ambuj Varshney; Haitham Hassanieh; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless transmitters; Wireless embedded systems; Physical-layer security; Radiometric fingerprinting; Radio frequency fingerprinting; Identification; Authentication; Backscatter communication; Internet of Things; Electrical Engineering with Specialisation in Networked Embedded Systems; Elektroteknik med inriktning mot nätverksbaserade inbyggda system; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Wireless communication is a key enabler for connecting billions of Internet of Things devices. For networked embedded devices operating on limited energy resources, wireless communication dominates the power consumption. LÄS MER
