‎in this paper‎, ‎we study a class of boundary value problem‎ ‎involving the p-laplacian oprator and singular nonlinearities‎. ‎we‎ ‎analyze the existence a critical parameter $lambda^{ast}$ such‎ ‎that the problem has least one solution for‎ ‎$lambdain(0,lambda^{ast})$ and no solution for‎ ‎$lambda>lambda^{ast}.$ we find lower bounds of critical‎ ‎parameter $lambda^{ast}$‎. ‎we use the method ...

Growing amount of information on biological sequences has made application of statistical approaches necessary for modeling and estimation of their functions. In this paper, sensitivity and specificity of the first and second Markov chains for prediction of genes was evaluated using the complete double stranded  DNA virus. There were two approaches for prediction of each Markov Model parameter,...

We re-investigated the surface deformation of the Kleifarvatn earthquake on Reykjanes Peninsula, an event that was dynamically triggered by a moderatesize magnitude 6.5 earthquake 80 km away on 17 June 2000. Two ERS-2 interferograms from descending and ascending tracks were formed and used in combination with campaign GPS measurements to invert for the source parameters of rectangular faults fo...

SUMMARY The primary concern in this paper is with the distributional results of classical extreme value theory, anc their developMent to apply to stationary processes. The main emphasis is on stationary sequences, where the theory is \'lell developed. :\esults available for continuous parameter processes are also described, but with particular reference to stationary normal processes.

Often, at the time when a performance model is built, some of its input parameters are not known exactly. This can be for a variety of reasons, such as the system itself not having been completed, a benchmarking process not yet having been carried out, or that precise estimates for the parameters are very difficult to obtain. In these situations, interval values can be used to express the uncer...

This work presents the dynamic response of a pavement plate resting on a soil whose inertia is taken into account in the design of pavements by rational methods. Thus, the pavement is modeled as a thin plate with finite dimensions, supported longitudinally by dowels and laterally by tie bars. The subgrade is modeled via Pasternak-Vlasov type (three-parameter type) foundation models and the movi...

A confidence interval is an interval (i.e., a range of values) estimate of a parameter of a population (e.g., a mean) calculated from a sample drawn from the population. A confidence interval has an associated confidence level, which is frequency with which a calculated confidence interval is expected to contain the population parameter. Confidence intervals are of interest in modeling and simu...

We prove ergodicity of a point process earthquake model combining the classical stress release model for primary shocks with the Hawkes model for aftershocks.

Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...
