Universal serial bus as a communication medium for prototype networked data acquisition and control systems - performance optimisation and evaluation
2018
Proceedings of the 2018 Federated Conference on Computer Science and Information Systems
In a prototype system, a PC or Mac computer with a general-purpose operating system is often selected as a host or root node for the USB bus and it acts as a central data collector, supervisory user interface ...
However, achieved communication performance is often unsatisfactory since USB stack drivers incorporated in Windows, Linux, or macOS operating systems are not optimised for such specific purposes. ...
Hence, the performance of such prototype configurations can be poor unless special measures are undertaken. ...

Performing digital ways of knowing: epistemic walks with methods-as-prototypes
2016
Graduate Journal of Social Science
unpublished
Inspired by emerging scholarship that looks at prototypes as a cultural and epistemic form, we delve into an exploration of methods (both traditional and digital) as prototypes open ended , non-instrumental ...
open sourcing, prototyping and hacking as part of our knowledgemaking practices gives us new ways to perform research as 'craft' -research as a process of 'making' , rather than just extracting, knowledge ...
Notwithstanding the different trajectories, we see both our explorations as animated by aspects of prototyping as a cultural heuristic: we explored methods (both digital and traditional ones) as prototypes ...
