We describe a new model which is able to model accurately the characteristics of subject motion, a dominant artefact in Functional Magnetic Resonance Images. Using the model, which is based on specific knowledge regarding the nature of the image acquisition, it is possible to correct for this motion which would otherwise render activation detection on the images invalid. We also present an init...

The social aspects of security are becoming increasingly important, now that security is at the foundation of the upcoming Internet Operating System. We will not be able to investigate the human side of security issues without considering the other side of the coin: surveillance. Some ‘Controlled Computing’ proposals are emerging, which at times recall Orwellian scenarios; on the other hand the...

Critical stresses necessary to generate dislocation glide loops in Czochralski silicon containing oxide precipitates have been investigated. Using three-point bending and etching techniques, it was possible to determine the minimum shear stress required to generate dislocation glide loops from controlled distribution of precipitates under constant-stress conditions. The generation of glide disl...

SUMMARY IBM's Microkernel, named Workplace OS microkernel 18], was the core component of Workplace OS, a portable successor of OS/2. The basic premise of Workplace OS work was: 1) IBM would adopt and improve the CMU Mach 3.0 microkernel for use on PDAs, the desktop, workstations, and massively parallel machines, and 2) that several operating system personalities would execute on the microkernel...

There is a continuous demand for new scheduling policies to address specific requirements of modern OSes. However, the implementation of such policies within an existing OS kernel raises many problems, mainly because optimizations within schedulers hinder code maintenance and implementation of existing schedulers is spread over the kernel. In this paper we motivate that schedulers form an aspec...

Introduction: We have continued study of the chemical nature of late accreted materials to the Earth-Moon system by examining the highly sidero-phile elements (HSE: Ru, Pd, Re, Os, Ir, Pt) contained in lunar impact-melt rocks. The HSE contained in melt rocks were largely added to the Moon during the period of time from the origin of the lunar highlands crust (4.4-4.5 Ga) to the end of the late ...

Re-Os isotopic analyses of a single organic-rich sedimentary rock unit (ORS) of known depositional age, and at three levels of regional hydrocarbon maturity, show that hydrocarbon maturation does not affect the ability the Re-Os chronometer to yield a depositional age for such rocks. We present Re-Os isotope analyses from the Late Devonian Exshaw Formation in the subsurface of the Western Canad...
