this paper deals with the boundary value problem involving the differential equationbegin{equation*}    ell y:=-y''+qy=lambda y, end{equation*} subject to the standard boundary conditions along with the following discontinuity  conditions at a point $ain (0,pi)$ begin{equation*}    y(a+0)=a_1 y(a-0),quad y'(a+0)=a_1^{-1}y'(a-0)+a_2 y(a-0),end{equation*}where $q(x),  a_1 , a_2$ are  real, $qin l...

emerging technologies such as biotheraputics are widely view as the source of new types of competitive advantage. despite their huge potential gaining advantages from these technologies requires adopting different types of managerial skills and insight than those utilized in the context of incremental improvements. this makes established firms particularly vulnerable to the challenges of these ...

In this paper, a discontinuity in beams whose intensity is adjusted by the spring stiffness factor is modeled using a torsional spring. Adapting two analyses in strong and weak forms for discontinuous beams, the improved governing differential equations and the modified stiffness matrix are derived respectively. In the strong form, two different solution methods have been presented to make an a...

in this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. the linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. to implement the method for the ...

The aim of the research is to optimize drilling process parameters while glass fi bre reinforced composites using solid carbide drill by integrating response surface methodology and Taguchi technique. Drilling includes cutting speed, Feed rate point angle with three levels. responses measured against these are; material removal rate, roughness, oversize delamination factor. ANOVA analysis carri...

the goal is assessing the diffusion magnetic resonance imaging (dmri) method effi ciency in characterizing focal hepatic lesions (fhls). about 28-fhl patients were studied in radiology and clinical imaging department of our university hospital using 1.5 tesla mri system between january 2010 and june 2011. patients underwent hepatic mri consisting of dynamic t1- and t2-weighted imaging. the dmri...

Imaging and spectroscopy are non-destructive techniques for determining fruit qualities. The qualities of table grapes (Vitis vinifera) such as soluble solids content (SSC), pH, fi rmness seedlessness key parameters. This research was focused on comparison between imaging in laboratory eld. results Partial least squares regression (PLSR) showed that the best coeffi cient determination (R2) pred...
