We consider the adaptive finite element discretization of parameter estimation problems for nonlinear elliptic partial differential equations. The idea is to use a gradient method on finite-dimensional space minimization least-squares residual. Since involves solution equations, it not accesable, and replaced by an approximation obtained elements. This results into perturbed method. (a posterio...

Important distributions used to model and analyse data in various real-life sciences such as natural sciences, engineering, medicine are the Weibull distribution, exponential Rayleigh distribution. The main objective of this paper is determine best evaluators compare them for distribution with three-parameters Weibull, Exponential Weibull. methods under consideration comparing parameter estimat...

This paper introduces an algorithm for network community detection called DEEN (Delete Edges and Expand Nodes) consisting of two simple steps. First edges of the graph estimated to connect different clusters are detected and removed, next the resulting graph is used for generating communities by expanding seed nodes. DEEN uses as parameters the minimum and maximum allowed size of a cluster, and...

In this paper, we propose a delay constrained spatio-temporal video rate control method for lossy channels where the effective channel rate available to the video encoder is time-varying. Target bit-rate constraint for encoding is derived, which guarantees in-time delivery of video frames. By using empirically obtained rate-quantization and distortionquantization relations of video, the distort...

This paper proposes a modified parameter mapping scheme for parallel model combination (PMC) method. The modification aims to improve the discriminative capabilities of the compensated models. It is achieved by the rearrangement of the distributions of state models in order to emphasize the contribution of the mean in the following process. Both distributions of speech model and noise model are...

the uniaxial compressive strength (ucs) of intact rocks is an important geotechnical parameter required for designing geotechnical and mining engineering projects. obtaining accurate estimates of the rock mass ucs parameter throughout a 3d geological model of the deposit is vital for determining optimum rock slope stability, designing new exploratory and blast boreholes, mine planning, optimizi...

by proposing a predictive method with no adjustable parameter and by using infinite dilution activity coefficients of components in binary mixtures obtained from unifac model, the binary interaction parameters (k12) in van der waals mixing rule (vdwmr) and orbey-sandler mixing rule (osmr) have been evaluated. the predicted binary interaction parameters are used in peng-robinson-stryjek-vera equ...

The observed two-point correlation functions of galaxies in redshift space become anisotropic due to the geometry of the universe as well as due to the presence of the peculiar velocity field. Expanding the induced anisotropies of the correlation functions with respect to the redshift z, we obtain explicit expressions for the deceleration parameter q0, the density parameter Ω0 and the derivativ...
