  1. 1. Externally positive systems : Analysis and control based on combinatorial polynomials

    Author : Liam Hamed Taghavian; Mikael Johansson; Cristian R. Rojas; Fabio Pasqualetti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear systems; External positivity; Optimization; Non-overshooting control; Combinatorics; Complete monotonicity; Majorization.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. READ MORE

  2. 2. Context-Based Micro-Training : Enhancing cybersecurity training for end-users

    Author : Joakim Kävrestad; Marcus Nohlberg; Steven Furnell; Rose-Mharie Åhlfeldt; Lothar Fritsch; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cybersecurity; training; usable; security; user; education; awareness; Information Systems; Informationssystem IS ;

    Abstract : This research addresses the human aspect of cybersecurity by developing a method for cybersecurity training of end-users. The reason for addressing that area is that human behaviour is widely regarded as one of the most used attack vectors. READ MORE

  3. 3. Solar PV in prosumer energy systems : A techno-economic analysis on sizing, integration, and risk

    Author : Nelson Sommerfeldt; Hatef Madani Larijani; Björn Palm; Michel Haller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrify everything; building energy systems; energy systems analysis; solar heat pump; investment analysis; Monte Carlo analysis; PVT; solar hybrid; Electrify everything; byggnadsenergisystem; energisystemanalys; solvärmepump; investeringsanalys; Monte Carlo analys; PVT; solhybrid; Energy Technology; Energiteknik; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. READ MORE

  4. 4. Lithium-ion batteries for off-grid PV-systems

    Author : Fabian Benavente; Göran Lindbergh; Anders Olof Lundblad; Saul Cabrera; Daniel Abraham; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; aging; partial cycles; DVA; EIS; NCA; stationary energy systems; PV systems; rural electrification.; Chemical Engineering; Kemiteknik;

    Abstract : This thesis provides a comprehensive and detailed analysis on the effect ofthe battery operation strategy on the lifetime of commercial lithium-ionbatteries and on the economics of off-grid photovoltaic (PV)-batterysystems.Lithium-ion batteries play a key role in the transition to a fossil-freesociety.

  5. 5. Automated Approaches for Formal Verification of Embedded Systems Artifacts

    Author : Predrag Filipovikj; Cristina Seceleanu; Jim Woodcock; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; Simulink; systems specifications; model-checking; formal verification; Computer Science; datavetenskap;

    Abstract : Modern embedded software is so large and complex that creating the necessary artifacts, including system requirements specifications and design-time models, as well as assuring their correctness have become difficult to manage. One challenge stems from the high number and intricacy of system requirements that combine functional and possibly timing or other types of constraints, which make them hard to analyze. READ MORE
