An interactive multi-display cluster-style rendering system is presented which runs on a single PC rather than a cluster of PCs. Many Direct3D features, including support for a programmable pipeline, are supported via a drop-in library replacement for Direct3D. While the presented profiling results are bandwidth limited, PCI cards have been used. It is expected that the greater bandwidth of PCI...

A local uniqueness property of holomorphic functions on realanalytic nowhere minimal CR submanifolds of higher codimension is investigated. A sufficient condition called almost minimality is given and studied. A weaker necessary condition, being contained a possibly singular real-analytic Levi-flat hypersurface is studied and characterized. This question is completely resolved for algebraic sub...

Radon contributes with more than 50% to the dose equivalent to the public coming from natural sources, and is a major risk factor for lung cancer occurrence (10–14%, in Europe, p.a.) which should be investigated. Insufficient data on radon levels exist for Romania up to now and further extensive surveys are needed. The paper presents a series of in-situ indoor radon data in various locations in...

An improved algorithm for blind modulation recognition of signals in cognitive radio (CR) is proposed in this paper, which uses the number of sinusoid component as a feature to classify FSK, BPSK, MSK and QPSK modulation schemes. Firstly, the received signal is preprocessed by short time filtering to improve the processing signal-to-noise ratio (SNR). Secondly, nonlinear operations are applied ...

The effective capacity (EC) has been recently established as a rigorous alternative to the classical Shannon’s ergodic capacity since it accounts for the delay constraints imposed by future wireless applications and their impact on the overall system performance. This paper develops a novel unified approach for the EC analysis of dispersed spectrum cognitive radio (CR) with equal gain combining...

The reaction of germylone (L)Ge (1) [L = 3-Ad-1-{C((t)Bu) = N(Mes)}C3H4N2] with 1 equivalent of MeOTf afforded a germyliumylidene ion [(L)GeMe](+)OTf(-) (2), while reactions with M(CO)5(thf) (M = Cr, Mo, W) gave the corresponding germylone-metal complexes [(L)Ge]M(CO)5 (3-5). The former possesses a pyramidal Ge center, whereas the latter display a planar geometry around the Ge atom. Computation...

Abstract NH 2 -UIO66 (NU) is a promising photocatalyst for the reduction of Cr(VI) to low-toxic Cr(III) driven by visible light under ambient conditions. However, main limitation in this process inefficient ligand metal charge transfer (LMCT) photo-excited electrons, which caused inherent energy gap (? E LMCT ). This study synthesized defective NU (NUX-H, where X molar equivalent modulator) wit...

We show that if (u,K) is a minimizer of the Mumford-Shah functional in an open set Ω of R, and if x ∈ K and r > 0 are such that K is close enough to a minimal cone of type P (a plane), Y (three half planes meeting with 120◦ angles) or T (cone over a regular tetrahedron centered at the origin) in terms of Hausdorff distance in B(x, r), then K is C equivalent to the minimal cone in B(x, cr) where...

We study the relation between support vector machines (SVMs) for regression (SVMR) and SVM for classification (SVMC). We show that for a given SVMC solution there exists a SVMR solution which is equivalent for a certain choice of the parameters. In particular our result is that for ǫ sufficiently close to one, the optimal hyperplane and threshold for the SVMC problem with regularization paramet...
