The double porosity model allows to compute the pressure at a macroscopic scale in a fractured porous media, but requires the computation of some exchange coe cient characterizing the passage of the uid from and to the porous media (the matrix) and the fractures. This coe cient may be numerically computed by some Monte Carlo method, by evaluating the time a Brownian particle spend in the matrix...

Average interpolating wavelets are used to construct multilevel representations of large data sets. The data is partitioned into disjoint blocks, and each block is transformed separately. Properties of wavelet coe cients guarantees that this partitioning does not introduce arti cial boundary e ects. Coe cients are organized in a data structure that is well suited for real-time visualization wit...

We show how lattice paths and the re ection principle can be used to give easy proofs of unimodality results. In particular, we give a \one-line" combinatorial proof of the unimodality of the binomial coe cients. Other examples include products of binomial coe cients, polynomials related to the Legendre polynomials, and a result connected to a conjecture of Simion.

We give a combinatorial rule for calculating the coe cients in the expansion of a product of two factorial Schur functions. It is a special case of a more general rule which also gives the coe cients in the expansion of a skew factorial Schur function. Applications to Capelli operators and quantum immanants are also given.

The Monetary Control Act of 1980 requires the Federal Reserve System to provide payment services to depository institutions through the twelve Federal Reserve Banks at prices that fully reflect the costs a private‐sector provider would incur, including a cost of equity capital (COE). Although Fama and French (1997) conclude that COE estimates are “woefully” and “unavoidably” im...

We quantify the identifying power of special regressors in heteroskedastic binary regressions with median-independent or conditionally symmetric errors. We measure the identifying power using two criteria: the set of regressor values that help point identify coe¢ cients in latent payo¤s as in (Manski 1988); and the Fisher information of coe¢-cients as in (Chamberlain 1986). We …nd for median-in...

The paper investigated the antihyperglycemic and antihyperlipidemic efficacy and antioxidant capacity of Chimonanthus nitens Oliv. leaf extract (COE) in combination of high-glucose-fat diet-fed and streptozotocin-induced diabetic model mice. Various physiological indexes in diabetic model mice were well improved especially by oral administration of high dose of COE; the results were listed as f...

For statistical design of an optimal "lter, it is probabilistically advantageous to employ a large number of observation random variables; however, estimation error increases with the number of variables, so that variables not contributing to the determination of the target variable can have a detrimental e!ect. In linear "ltering, determination involves the correlation coe$cients among the inp...

This paper shows an application of hybrid PV/wind energy and battery storage in the islanded area. work’s main target allows distributed resources to contribute efficiently economic feasibility enhance environmental impact renewable source. Several factors such as levelized cost (COE), greenhouse gas (GHG) emissions, loss power supply probability are studied. A combined solution is compromise a...
