    Jan De Muijnck-Hughes – Type-Driven Development of Communicating Systems using Idris (6th December, 2017)

    by  • December 1, 2017 • DSG Research Seminars: Logic and Programming Languages

    Time, Location: 14:15, Wednesday 6 December, EM G.61. Speaker: Jan De Muijnck-Hughes Title: Type-Driven Development of Communicating Systems using Idris Abstract Communicating protocols are a cornerstone of modern system design. However, there is a disconnect between the different tooling used to design, implement and reason about these protocols and their implementations. Session Types are...

    Blair Archibald – Branching Out: Skeletons for Parallel Tree Search (22nd November, 2017)

    by  • November 10, 2017 • DSG Research Seminars: Logic and Programming Languages

    Speaker: Blair Archibald, University of Glasgow Time and location: 14:15, Wednesday 22nd November, EM 1.70. Abstract Tree search problems are everywhere, from exploring mathematical objects and scheduling factories to making the most effective drugs possible. While these problems, in essence, lend themselves well to parallelsim, often this is done on a per-application or per-instance...

    Ross Duncan – Substitution, binding, and pattern matching in string diagrams (8th November, 2017)

    by  • November 4, 2017 • DSG Research Seminars: Logic and Programming Languages

    Speaker: Ross Duncan, University of Strathclyde Time and location: 15:15, EM 3.07 Abstract: Diagrams are widely used in science and engineering; well known examples include electronic circuit diagrams, Feynman diagrams, proof-nets, petri-nets, and countless others. All these diagrams share the same basic features because they are all presentations of monoidal categories — one of...

    Rajiv Murali – A Rigorous Approach to Use Case Driven Development in SysML (18th October, 2017)

    by  • October 2, 2017 • DSG Research Seminars: Logic and Programming Languages

    Time and location: 14:30, EM 1.70 Abstract: Use cases (UC) are a popular technique used to define the goals of a system. As part of use case driven development (UCD), these goals drive the analysis, design and testing of the system. An integral part of UCD, are document-based use case specifications (UCS) that help...

    Daniel J. Sorin – Designing Processors to Accelerate Robot Motion Planning (15 November, 2017)

    by  • September 22, 2017 • DSG Research Seminars: Logic and Programming Languages

    Abstract: We have developed a hardware accelerator for motion planning, a critical operation in robotics. I will present the microarchitecture of our accelerator and describe a prototype implementation on an FPGA. Experimental results show that, compared to the state of the art, the accelerator improves performance by three orders of magnitude and improves power...

    John Power – Category theoretic semantics for theorem proving in logic programming: embracing the laxness (16 August, 2017)

    by  • September 8, 2017 • DSG Research Seminars: Logic and Programming Languages

    A propositional logic program P may be identified with a P_fP_f-coalgebra on the set of atomic propositions in the program. The corresponding C(P_fP_f)-coalgebra, where C(P_fP_f) is the cofree comonad on P_fP_f, describes derivations by resolution. That correspondence has been developed to model first-order programs in two ways, with lax semantics and saturated semantics, based...
