Turning hard problems on their heads

Much of the difficulty in assessing theories of consciousness stems from their advocates not supplying adequate or convincing characterisations of the phenomenon (or data) they hope to explain. Yet, to make any reasonable assessment this is precisely what is required, for it is not as if our ‘pre-theoretical’ intuitions are philosophically innocent. In what follows, I will attempt to reveal, us...

Cutting Disturbances in Hard Turning Process

Assumption of cutting disturbances in hard turning process (caused by variations in depth of cutting, high passive force Fp or small tool nose radius) could be confirmed with several indicators. These indicators can be monitored during turning process(forces, vibrations, sound, etc.) or after process has been finished (roughness, temperature, wear, etc). Variation of depth of cutting as well as...

Scheduling of Hard Real-Time Multi-Thread Periodic Tasks

In this paper we study the scheduling of parallel and real-time recurrent tasks. Firstly, we propose a new parallel task model which allows recurrent tasks to be composed of several threads, each thread requires a single processor for execution and can be scheduled simultaneously. Secondly, we define several kinds of real-time schedulers that can be applied to our parallel task model. We distin...

We present the design and implementation of Arachne, a threads system that can be interfaced with a communications library for multi-threaded distributed computations. In particular, Arachne supports thread migration between heterogeneous platforms, with dynamic stack size management and recursive thread functions. Arachne is eecient, exible and portable | it is based entirely on C and C++. To ...
