in this research, a first order markov chain model was applied to simulate soil salinity in nine standard depths and 10 classes in the cultivated pistachio areas of ardakan city. transition probability matrix, kernel and uniform distribution were used to simulate 500000 soil profiles. results indicate kernel function could reproduce soil salinity values with statistical criteria (i.e. mean, sta...

A significant number of myocardial diseases are accompanied by increased synthesis and degradation of the extracellular matrix (ECM) as well as by changed maturation and incorporation of ECM components. Important groups of enzymes responsible for both normal and pathological processes in ECM remodeling are matrix metaloproteinases (MMPs). These enzymes share a relatively conserved structure wit...

Let (Ω,Σ,μ) be a σ -finite complete measure space and C be the field of complex numbers. By L(μ ,CN), we denote the linear space of all equivalence classes of CN-valued Σ-measurable functions on Ω that are identified μ-a.e. and are considered as column vectors. Let M◦ denote the linear space of all functions in L(μ ,CN) that are finite a.e. With the topology of convergence in measure on the set...

In this paper we introduce a four-parameter generalized Weibull distribution. This new distribution has a more general form of failure rate function. It is more general for modeling than six ageing classes of life distributions with appropriate choices of parameter values, so it can display decreasing, increasing, bathtub shaped, unimodal, increasing-decreasing increasing and decreasing-increas...

in this ever-changing business scenario, the manufacturing product industries have to be in position to rec-ognize the ever changing pulse and demands of the market. customer satisfaction and quality management has become a strategic issue for companies in the new millennium. quality function deployment (qfd) lit-erature suggests that building up the house of quality (hoq) is not a difficult ta...

one of the main members of the large aggregating proteoglycans (pgs) family is versican which is able to bind to hyaluronate. versican is a chondroitin sulfate proteoglycan and is a key ingredient of the extracellular matrix.  due to its widespread expression in the body, versican is involved in cell adhesion, proliferation and migration. induced expression of versican is often observed in tiss...

An efficient numerical method is developed for evaluating φ(A), where A is a symmetric matrix and φ is the function defined by φ(x) = (ex − 1)/x = 1+ x/2 + x2/6+ .... This matrix function is useful in the so-called exponential integrators for differential equations. In particular, it is related to the exact solution of the ODE system dy/dt = Ay + b, where A and b are t-independent. Our method a...
