this article examines statistical inference for  where and are independent but not identically distributed pareto of the first kind (pareto (i)) random variables with same scale parameter but different shape parameters. the maximum likelihood, uniformly minimum variance unbiased and bayes estimators with gamma prior are used for this purpose. simulation studies which compare the estimators are ...

In this study, Doppler signals recorded from internal carotid artery of 45 subjects were processed by PC-computer using classical (fast Fourier transform) and model-based (autoregressive, moving average, autoregressive moving average (ARMA) methods) methods. Power spectral density estimates of internal carotid arterial Doppler signals were obtained using these spectral analysis methods. The var...

The antenna radiation characteristic is the important parameter to select the shape of antenna and triangular patch antenna gives the better antenna characteristic as compared to other shape antenna with less geometrical structure. Objective of our work is to enhance the characteristics of triangular patch antenna .In this paper we discussed about some previous applied techniques to improve the...

Erythrocyte aggregation and dissociation play an important role in the determination of hemodynamical properties of blood flow inmicrocirculation.This paper intends to investigate the adhesion and dissociation kinetics of erythrocytes through computational modeling.The technique of immersed boundary-fictitious domain method has been applied to the study of erythrocyte aggregates traversing mode...

We studied the shape of L1210 leukaemia cells adhering in a protein-free medium to sulfonated (styrene/methyl methacrylate) copolymer surfaces of two sulfonic group densities, and thus of differing wettability. The use of our image analysis method and the mathematical procedure [Kowalczynska, H.M. et al, Colloids Surfaces B: Biointerfaces, 30 (2003) 193-206.] allowed us to calculate the values ...

The silicone stent has been widely used to re-establish airway patency for patients with airway stenosis. The ideal shape of the stent should be well adapted to the tracheobronchial anatomic structures, and its optimal length should cover the entire inner wall of the stenotic airway. Although the silicone Y-stent was developed as a dedicated prosthesis for main carinal stenosis, we often encoun...

In this two-part study, relationships between the cloud gamma size distribution shape parameter, microphysical processes, and cloud characteristics of nonprecipitating shallow cumulus clouds are investigated using large-eddy simulations. In Part I, the dependence of the shape parameter (which is closely related to the distributionwidth) on cloud properties andprocesseswas investigated.However, ...

Vascular stenosis is a pathological hallmark of atherosclerosis, the leading cause cardiovascular diseases such as stroke and myocardial infarction. While stenosis-induced thrombus formation has been extensively studied using in vivo vitro vascular models, transient dynamic process platelet aggregation remains unclear due to lack analytical tools with both high spatial temporal resolution. Here...

Minimization of power of higher order modes (HOMs) in a multicell cavity was done using derivatives of the parameter defining losses with respect to geometric parameters of the cavity cells. For the Cornell Energy Recovery Linac most dangerous are dipole modes causing beam break-up (BBU). As a start point of optimization the shape with minimal losses at the fundamental mode was taken. Further c...
