Abstract is a tool for verifying reachability properties of concurrent C programs. It moderates the trace-space explosion problem, aggravated by thread alternation, through utilizing PC-DPOR and C-Intp techniques. The technique constructs constrained dependency graph to refine dependencies between transitions. With this basis, inherent imprecision dependence over-approximation can be overcome. ...

In this paper we consider   multivariate Lagrange mean-value interpolation problem, where interpolation parameters are integrals over spheres. We have   concentric spheres. Indeed, we consider the problem in three variables when it is not correct.  

Introduction. Consider a Jacobi form φ(τ, z) = ∑ n,r c(n, r)q ζ whose Fourier coefficients c(n, r) are algebraic numbers. Let p be an odd prime. In this paper we associate to φ a Λ-adic p-ordinary form in the sense of [4]. The construction comes from the map Dν introduced in [2], Theorem 3.1. This map associates to a Jacobi form a family of modular forms parametrised by ν. We obtain the two-var...

introduction in ct imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. in order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. materials and methods the presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

We present an efficient algorithm for visualizing the effect of black holes on its distant surroundings as seen from observer nearby in orbit. Our solution is GPU-based and builds upon a two-step approach, where we first derive adaptive grid to map 360-view around distorted celestial sky, which can be directly reused different camera orientations. Using grid, rapidly trace rays back through spa...

Aiming at the tracing problem of ambient air quality exceeding standard caused by unorganized emission multiple pollution sources in chemical industry park, an method based on OK-IGSO integrated algorithm is proposed. First all, ordinary Kriging (OK) geostatistics applied to prediction and interpolation atmospheric pollutants so that distribution closer reality; Then, improved glowworm (IGSO), ...

We study properties of W01,p(R+,tβ) — the completion C0∞(R+) in power-weighted Sobolev spaces W1,p(R+,tβ), where β∈R. Among other results, we obtain analytic characterization for all Our analysis is based on precise two trace operators: Tr0(u)≔limt→0u(t) and Tr∞(u)≔limt→∞u(t), which leads to asymptotic behavior functions from near zero or infinity. The obtained statements can contribute proper ...

Local structural property of an image is often considered in image enhancement with various high/low pass filters. Spatial association indexes (autocorrelation, covariance, and variogram) have been commonly used to characterize the local structure of surfaces for data interpolation in kriging. Singularity is another index measuring the scaling invariant property of measures from a multifractal ...

Theoretically, the Delft approach of surface-related multiple eliminationcan be applied in three dimension, as long as the sourceand receiver coverage is dense enough. In reality, such a dense coverage is still far from reach, using the available multi-streamer acquisition system. One way to fill the gap is to massively interpolate the missing sources and receivers in the survey, which requires...
