  1. 1. Free software to open hardware: Critical theory on the frontiers of hacking

    Författare :Johan Söderberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :hackers; constructivism; innovation; free software; critical theory; immanent critique; technology; lay expertise; open hardware;

    Sammanfattning : Starting from the experiences of hackers developing free software and open hardware, this thesis addresses some key and recurrent themes in the field of Science and Technology Studies (STS). It poses the question: how are technologies conceptualised, constructed and used in ways that render some aspects of them transparent, while leaving others opaque? This question is complicated by the fact that what is visible and transparent to some will remain opaque to others, depending on the level of technical expertise commanded. LÄS MER

  2. 2. Protection for Multiterminal HVDC Grids - A Digital Contribution

    Författare :Ilka Jahn; Staffan Norrga; Hans-Peter Nee; Dirk Westermann; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; power system protection; IED; real-time systems; test bench; field programmable gate array; open-source hardware; open-source software; power engineering education; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of this thesis is to (1) enhance understanding of mechanisms that are important for the protection of high-voltage direct-current (HVDC) grids, and (2) suggest possible technical solutions. To that end, digital technologies were used both in simulation, as well as in a laboratory environment. LÄS MER

  3. 3. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections

    Författare :Carlos Jorques Moreno; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Combustion; Pilot-Main Injection; Pilot Mass Estimation; Cylinder Volume Estimation; Bayesian Estimation; In-Cycle Combustion Controllability; In-Cycle Combustion Control; Model Predictive Combustion Control; Stochastic Combustion Optimization; Hardware Quantification;

    Sammanfattning : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

  4. 4. Industrial Robot Programming

    Författare :Klas Nilsson; Institutionen för datavetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Software architecture.; Embedded systems; Open systems; Robot control; Industrial robots; Robot programming; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. LÄS MER

  5. 5. Design and Security Analysis of TRNGs and PUFs

    Författare :Yang Yu; Elena Dubrova; Zhonghai Lu; Ilia Polian; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryptographic primitive; Physical Unclonable Function; True Random Number Generator; Hardware security; Side-channel analysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : True Random Number Generators (TRNGs) and Physical Unclonable Functions (PUFs) are two important types of cryptographic primitives. TRNGs create a hardware-based, non-deterministic noise that is often used for generating keys, initialization vectors, and nonces for various applications that require cryptographic protection.
