Studying brain mechanisms underlying the prediction of observed action, the dorsal premotor cortex (PMd) has been suggested a key area. The present study probed this notion using repetitive transcranial magnetic stimulation (rTMS) to test whether interference in this area would affect the accuracy in predicting the time course of object directed actions performed with the right hand. Young and ...

A Software Transactional Memory is a concurrency control mechanism that executes multiple concurrent, optimistic, lockfree, atomic transactions, thus alleviating many problems associated with conventional mutual exclusion primitives such as monitors and locks. With the advent of massive multi-cores, more transactions can be initiated concurrently, however resulting in an increase in the percent...

This document presents the working plan for a STSM submitted by Jean-Julien Filatriau at InfoMus Lab, DIST-University of Genova, Italy. J-J Filatriau is PhD student at Université Catholique de Louvain (UCL, Belgium), under the co-supervision of Dr. Benoit Macq (UCL) and Dr. Daniel Arfib (LMA-CNRS, Marseille, France). His PhD deals with the gestural control of sonic textures synthesis; from now,...

Shared data synchronization is at the heart of the multicore revolution since it is essential for writing concurrent programs. Ideally, a synchronization technique should be able to fully exploit the available cores, leading to improved performance. However, with the growing demand for energy-efficient systems, it also needs to work within the energy and power budget of the system. In this pape...

Spaceborne imaging spectrometers are expected to facilitate regional-scale vegetation analyses with multi-season hyperspectral imagery. However, we still lack a better understanding on both whether approaches favorable over single-season approaches, as well the benefits of compared multispectral data. Our study investigates potential unmixing simulated Environmental Mapping and Analysis Program...

We propose a notarized federated identity management model that supports efficient user authentication when providers are unknown to each other. Our model introduces a notary service, owned by a trusted third-party, to dynamically notarize assertions generated by identity providers. An additional feature of our model is the avoidance of direct communications between identity providers and servi...

Increasing traac on highways and in the air has in the recent years motivated the design of hierarchical hybrid control systems. In this paper we will propose a hierarchical hybrid control system for the control of traac on sea, a Sea Traac Management System (STMS). The motivation is to reduce delays and improve the eeciency and safety in increasingly overcrowded harbors, busy straits and narro...

To address the need for improved efficiency and to support an ever-increasing feature set, the specification and implementation of state-of-the-art transactional memory (TM) systems are vastly different than the pioneering systems from a decade ago. An unfortunate side-effect of this shift is that some of the early theoretical work on TM correctness does not apply to these new systems. This pap...

We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). Unlike existing approaches, we consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Also, our model captures dynamics related to the execution of both transactional r...
