We consider the problem of reliable broadcast in an infinite grid (or finite toroidal) radio network under Byzantine and crash-stop failures. We present bounds on the maximum number of failures that may occur in any given neighborhood without rendering reliable broadcast impossible, We improve on previously proved bounds for the number of tolerable Byzantine faults [6]. Our results indicate that it is possible to achieve reliable broadcast if slightly less than one-fourth fraction of nodes in any neighborhood are faulty, and impossible otherwise. We also show that reliable broadcast is achievable with crash-stop failures if slightly less than half the nodes in any given neighborhood may be faulty. In particular, we establish exact thresholds under a specific distance metric. Copyright 2005 ACM.

MOSFET gate *** limits are examined with respect to time-dependent breakdown, defects, plasma process damage, mobility degradation, poly-gate depletion, inversion layer thickness, tunneling leakage, charge trapping, and gate delay. It is projected that the operating field will stay around 5MV/cm for reliability and optimum speed. Tunneling leakage prevents scaling below 2nm, which is sufficient for MOSFET scaling to 0.05 mu m.
In this paper, we aim at modeling video sequences that exhibit temporal appearance variation. The dynamic texture model proposed in [6] is effective to model simple dynamic scenes. However, because of its over-simplif...

Smart mobile devices carry an enormous amount of sensitive personal data of their owners. The access to this data by mobile operating systems and mobile applications is regulated by a corresponding security and permissions framework. In this paper we discuss the privacy and security concerns that have risen from the permissions model in the Android operating system, along with two shortcomings that have not yet been addressed up to date. We focus on personal data and propose a smartphone data taxonomy as a tool to highlight these concerns. Additionally, we study the impact of the applications' evolutionary increment of permission requests from both the user's and the developer's point of view and finally, we propose a series of remedies to the privacy and security corrosion.
computer is now emerging as a new crime tool. The growing menace from crimes committed against computers, or against information on computers, is commanding the attention of various nations. The phenomenal growth of c...

In this work, we have used Density Functional Theory to explore the effect of O, Ba and Ba-O adsorbates on W surfaces to assess the impact of these adsorbates on the work function and surface stability for eight different W surface orientations. A discussion of the impact of different surface adsorbates on the surface stability and work function is presented, together with newly discovered stable Ba-O arrangements on the most stable W surfaces. Finally, we discuss the potential role of high index surfaces in electron emission, and the possible impact of W diffusion kinetics on the prevalence of high index surfaces.
