A simple framework utilizing functional specifications for musical inter... Read More about Fun with Interfaces (SVG Interfaces for Musical Expression).

Return to temperament (In digital systems) (2018)
Presentation / Conference Contribution

Considering the generation of musical tunings, it is reasonable to expect that the many constructs contained in Functional programming languages may provide useful tools for exploring both conventional and new tunings. In this paper we present a numb... Read More about Return to temperament (In digital systems).

System and method for synchronous task dispatch in a portable device (2017)
Patent

A portable computing device synchronously offloads tasks from a first processing resource to an alternative processing resource.

HRF-relaxed: Adapting HRF to the complexities of industrial heterogeneous memory models (2015)
Journal Article

© 2015 ACM. Memory consistency models, or memory models, allow both programmers and program language imple-menters to reason about concurrent accesses to one or more memory locations. Memory model specifications balance the often conflicting needs fo... Read More about HRF-relaxed: Adapting HRF to the complexities of industrial heterogeneous memory models.

Method for memory consistency among heterogeneous computer components (2014)

A method, computer program product, and system is described that determines the correctness of using memory operations in a computing device with heterogeneous computer components. Embodiments include an optimizer based on the characteristics of a Se... Read More about Method for memory consistency among heterogeneous computer components.

Outside the block syndicate: Translating Faust's algebra of blocks to the arrows framework
Presentation / Conference Contribution

Folklore has it that Faust’s algebra of blocks can be represented in Hughes’ algebra of Arrows. In this paper we formalise this understanding, showing that blocks can indeed be encoded with Causal Commutative Arrows.
Whilst an interesting finding in... Read More about Outside the block syndicate: Translating Faust's algebra of blocks to the arrows framework.
