The Kangan Formation (Early Triassic) is one of the most important gas reservoirs in the Zagros fold-thrust belt. The study area is located in the west of Hormozgan Province and on the Gavbandi highland. This field is one of the important gas production anticlines in the SW Iran. To investigate the reservoir quality of the Kangan Formation in these wells, 163 microscopic thin sections were prep...

The aim of this paper is to present a proof of the equivalence of the equalities N P = PCP(log log n; 1) and P = N P. The proof is based on producing long pseudo-random bit strings through random walks on expander graphs. This technique also implies that for any language in N P there exists a restricted veriier using log n + c, c is a constant, random bits. Furthermore, we prove that the equali...

Panax Geothermal Limited is developing a geothermal resource in South Australia, the Limestone Coast Project, which is a conventional “hot aquifer” reservoir in a deep sedimentary basin. The initial development is the Pretty Hill Formation sandstones in the Penola Trough of the Otway Basin. The area is an exploited gas basin with modern 3D seismic and excellent existing petroleum well data cove...

The growing popularity of portable and mobile computing and communication devices along with the introduction of wireline broadband networks is fueling demand for wireless broadband networks. Since ATM has been accepted as the standard for broadband integrated service networks we consider the problem of providing \ATM-like services" to mobile devices. In this paper, we discuss the fundamental i...

We investigate the error growth, that is, the growth in the distance E between two typical solutions of a weather model. Typically E grows until it reaches a saturation value E(s). We find two distinct broad log-linear regimes, one for E below 2% of E(s) and the other for E above. In each, log (E/E(s)) grows as if satisfying a linear differential equation. When plotting d log(E)/dt vs log(E), t...

The complex interplay between depositional facies and diagenesis in dolostones presents numerous challenges for calculating petrophysical properties from wireline logs. Complex pore geometries and mineralogies control rock petrophysical properties, and equations for calculating porosities and saturations must therefore be tailored to specific pore geometry-mineralogy combinations. The complex m...

In this paper, we consider the extreme behavior of a Gaussian random field f(t) living on a compact set T . In particular, we are interested in tail events associated with the integral ∫ T e f(t)dt. We construct a (nonGaussian) random field whose distribution can be explicitly stated. This field approximates the conditional Gaussian random field f (given that ∫ T e f(t)dt exceeds a large value)...

Information from the full diffusion tensor (DT) was used to compute voxel-wise genetic contributions to brain fiber microstructure. First, we designed a new multivariate intraclass correlation formula in the log-Euclidean framework. We then analyzed used the full multivariate structure of the tensor in a multivariate version of a voxel-wise maximum-likelihood structural equation model (SEM) tha...

Consider the standard, one dimensional, nonlinear filtering problem for diffusion processes observed in small additive white noise: dXt = b(Xt)dt + dBt , dY ε t = γ(Xt)dt + εdVt , where B·, V· are standard independent Brownian motions. Denote by qε 1(·) the density of the law of Ξ1 conditioned on σ(Y ε t : 0 ≤ t ≤ 1). We provide “quenched” large deviation estimates for the random family of meas...

Operators worldwide are in various stages of preparing for or deploying IPv6 in their networks. These operators often face difficult challenges related to IPv6 introduction, along with those related to IPv4 run-out. Operators will need to meet the simultaneous needs of IPv6 connectivity and continue support for IPv4 connectivity for legacy devices with a stagnant supply of IPv4 addresses. The I...
