Computer industry has adopted multi-threaded and multi-core architectures as the clock rate increase stalled in early 2000’s. It was hoped that the continuous improvement of single-program performance could be achieved through these architectures. However, traditional parallelizing compilers often fail to effectively parallelize general-purpose applications which typically have complex control ...

This science-fiction prototype comprises two stories discussing potential futures of human hearing. The stories focus on the potential consequences of two speculative factors affecting human behaviour and societies: 1) sound conditioning technology, and 2) the mass hearing impairment. The stories will also be presented in a gallery space by means of the communicating arts: a prototype, moving i...

We present a generalized committed choice construct for concurrent programs that interact with a shared store. The generalized committed choice (GCC) allows multiple computations from different alternatives to occur concurrently and later commit to one of them. GCC generalizes the traditional committed choice in Dijkstra’s Guarded Command Language to handle don’t know non-determinism and also a...

Data dependencies between instructions greatly impede instruction-level parallelism. Recently two hardware techniques – Value Prediction and Value Reuse – have been proposed to overcome the limits imposed by data dependencies. We introduce a new hardware scheme for exploiting speculative value reuse by using value prediction. We propose a new microarchitecture which uses value prediction to pro...

Speculative design is an emerging rhetorical strategy in design practices and research to raise public awareness in social agendas that have been little explored. As a stream of this type of research, we propose speculative visualization that aims to achieve speculative design by utilizing techniques from data visualization and graphic design. Specifically, speculative visualization represents ...

The article explores aspects of the dialectical deductive process concept free will, principal organizing and operating in Hegel's Philosophy Right. In this respect, it reflects on structural components which is starting point science right, since relation right for Hegel realization will. parallel, attempts to highlight some crucial points with respect speculative method that underlies Hegelia...

and an anonymous referee for helpful comments and to Steve Nafziger for research assistance. 1 " It is clear from the preceding that every " art " [technique] has its speculative and its practical side. Its speculation is the theoretical knowledge of the principles of the technique; its practice is but the habitual and instinctive application of these principles. It is difficult if not impossib...
