    This paper proposes a method to synthesise controllers for systems with possibly infinite number of states that satisfy a specification given as an LTL\◦ formula. A common approach to handle this problem is to first compute ...
  • Adversarial risk analysis for first-price sealed-bid auctions.

    Ejaz, Muhammad; Joshi, Chaitanya; Joe, Stephen (Wiley, 2021)
    Adversarial risk analysis (ARA) is an upcoming methodology that is considered to haveadvantages over the traditional decision-theoretic and game-theoretic approaches. ARAsolutions for first-price sealed-bid (FPSB) auctions ...
  • Cylindrical spikes

    Moughal, Muhammad Zubair Ali; Lim, Woei Chet (IOP Publishing LTD, 2021)
    The Geroch/Stephani transformation is a solution-generating transformation, and may generate spiky solutions. The spikes in solutions generated so far are either early-time permanent spikes or transient spikes. We want to ...
  • FilmGrain

    Simmons, Rowan; Apperley, Mark; Soo, Chin-En Keith (2019)
    Films are an integral part of our cultural zeitgeist, as time goes on, they have become more than entertainment, they have become a mirror that we point at ourselves in order to explore issues and our position in the world. ...
  • Dynamic property enforcement in programmable data planes

    Neves, Miguel; Huffaker, Bradley; Levchenko, Kirill; Barcellos, Marinho (2021)
    Network programmers can currently deploy an arbitrary set of protocols in forwarding devices through data plane programming languages such as P4. However, as any other type of software, P4 programs are subject to bugs and ...
  • Slowdown and heating of interstellar neutral helium by elastic collisions beyond the heliopause

    Swaczyna, P.; Rahmanifard, F.; Zirnstein, E. J.; McComas, David J.; Heerikhuisen, J. (IOP Publishing, 2021)
    Direct sampling of interstellar neutral (ISN) atoms close to the Sun enables studies of the very local interstellar medium (VLISM) around the heliosphere. The primary population of ISN helium atoms has, until now, been ...
  • Concrete ephemeriality

    Simmons, Rowan; Soo, Chin-En Keith (2020)
    Concrete ephemerality is a project designed to capture something that was once transitory and seeks to create something concrete from it. With ever more tracking and aggregation of our digital lives, online identities that ...
  • A note on families over a p-adic disk, circa 2012

    Delbourgo, Daniel; Smith, Lachlan (2012)
    The following notes discuss how the local conditions H¹ₑ and H¹𝓰 of Bloch-Kato vary in an analytic family, culminating in the proof of a control theorem (Theorem 1.1).
  • On ensemble techniques for data stream regression

    Gomes, Heitor Murilo; Montiel, Jacob; Mastelini, Saulo Martiello; Pfahringer, Bernhard; Bifet, Albert (IEEE, 2020)
