large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in alberta, most of this being bitumen of viscosity greater than 106 cp in the grosmontformat...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

From the degree zero part of the logarithmic vector fields along an algebraic hypersurface singularity we identify the maximal multihomogeneity of a defining equation in form of a maximal algebraic torus in the embedded automorphism group. We show that all such maximal tori are conjugate and in one–to–one correspondence to maximal tori in the linear jet of the embedded automorphism group. These...

A fast algori thm for Gaussian eliminat ion over GF(2) is proposed. The proposed algorithm employs binary search technique to locate l s along the colum ns of the large binary matrix being triangular ized. T he algori thm requires 2m 2 + m log211 2m bit operations to triang ularize an II X m matrix on a bit-array with 11 processors and m + 2 + l"log2nl bits of vertica l memory per processor . D...

The paper concerns numerical modelling of complicated GeoTechnical problems as mine stability, performance of underground radioactive waste repositories or microstructure modelling of geocomposites. The modelling uses finite elements and parallel computing based on overlapping domain decomposition. Important implementation issues for this approach are discussed: inexact solution of subproblems,...

A fundamental postulate of quantum mechanics states that a measurement of a quantum system causes the collapse of the wave function. This is in contrast to the smooth, continuous, deterministic time evolution of the wave function in between measurements, governed by the Schrodinger equation. The latter is similar to classical physics; the former is unique to quantum mechanics. (Note that many ...

Dünya çapında ekonomik ve çevresel maliyetine rağmen şişelenmiş sulara olan ilgi artmaktadır. Şişelenmiş erişim gücü az kesimler ise şehirlerde bulunan tatlı su çeşmelerinden içme suyu ihtiyaçlarını karşılamaya çalışmaktadırlar. Bu çalışmada Konya’da satılan sulardan 24 adet doğal kaynak suyu, 4 mineralli 28 alınan numunelerde başlıca dezenfeksiyon yan ürünlerinden trihalometan (THM) (kloroform...

Background: Heat cured acrylic resin is the most widely used material in the manufacture ofdenture base, but has mechanical properties weakness (transversal strength and impact strength). Alternative to increase the mechanical properties of acrylic resin is the utilization of reinforcing fibre that is polyethylene fibre that has advantage such as good aesthetic, easy to manipulate and increase ...
