Dynamical systems have attracted much interest since the discovery of chaotic phenomena I I ]. Many applications to physical systems have appeared [2 ]. The definition of dynamical systems is the following [3]: Let M be a smooth manifold, I a measure on M defined by a continuous positive density, /,: M-M a one-parameter group of measure-preserving diffeomorphisms. Then the collection (M, p, /,)...

[1] Knowledge of trace gas fluxes at the land surface is essential for understanding the impact of human activities on the composition and radiative balance of the atmosphere. An ability to derive fluxes at the regional scale (on the order of 10–10 km), at the scale of ecosystems and political borders, is crucial for policy and management responses. Lagrangian (‘‘air mass-following’’) aircraft ...

Empirical evidence suggests that financial risk has a heavy-tailed profile. Motivated by recent advances in the generalized quantile measure, we propose tail value-at-risk (TVaR)-based expectile, which can capture compared with classic expectile. In addition to showing measure is well-defined, properties of TVaR-based expectiles as measures were also studied. particular, give equivalent charact...

Abstract An experimental apparatus has been designed to investigate interaction among CO 2 injection parameters. It is an integrated-closed system of measurement kits that aimed obtain interfacial tension, swelling factor, and viscosity data simultaneously. The had successfully tested measure properties dead live oils mixed with in high-pressure high-temperature environment. study was completed...

BACKGROUND The quality of transitional care is associated with important health outcomes such as rehospitalization and costs. The widely used Care Transitions Measure (CTM-15) was developed with a classic test theory approach; its short version (CTM-3) was included in the CAHPS Hospital Survey. We conducted a psychometric evaluation of both measures and explored whether item response theory (IR...

abstract: this paper discusses two topics. at first, it uses continuous wavelet (morlet) transform, coherency, and phase angle analysis to study the effect of mean volatility in opec crude oil prices, wti crude oil prices, brent crude oil prices and iran’s crude oil prices on the iran’s reer. to this end, the monthly data of the variables for years 2003 to 2012 is used. coherency analysis revea...

Chip Multiprocessor Systems (CMPs) rely on a cache coherency protocol to maintain memory access coherence between cached data and main memory. The Hammer coherency protocol is appealing as it eliminates most of the space overhead when compared to a directory protocol. However, it generates much more traffic, thus stressing the NoC and having worse performance in terms of power consumption. When...

We derive a new pointwise characterization of the subdifferential of the total variation (TV) functional. It involves a full trace operator which maps certain L vectorfields to integrable functions with respect to the total variation measure of the derivative of a bounded variation function. This full trace operator extents a notion of normal trace, frequently used, for example, to characterize...
