Geological information such as geological interfaces is important for the design of underground excavation and supporting measures. This in turn requires a method to predict accurately locations gap areas between boreholes. study presents generalized additive model (GAM) location interfaces. The performance GAM evaluated using both simulated data borehole determination rockhead two different fo...

Given a finite set of eigenvalues regular Sturm-Liouville problem for the equation -y{\prime}{\prime}+q(x)y={\lambda}y, potential q(x) which is unknown. We show possibility to compute more without any additional information on q(x). Moreover, considering with boundary conditions y{\prime}(0)-hy(0)=0 and y{\prime}({\pi})+Hy({\pi})=0, where h, H are some constants, we complete its spectrum neithe...

the padmakar-ivan (pi) index is a wiener-szeged-like topological index which reflectscertain structural features of organic molecules. the pi index of a graph g is the sum of alledges uv of g of the number of edges which are not equidistant from the vertices u and v. inthis paper we obtain the second and third extremals of catacondensed hexagonal systems withrespect to the pi index.

BACKGROUND: With the introduction of highly active antiretroviral therapy (HAART) the outlook of HIV/AIDS has changed from a killer disease to a treatable chronic infectious one. However HAART is associated with some metabolic disorders some of which are now being seen in people living with HIV/ AIDS (PLWHA) accessing care from our centre. OBJECTIVE: To determine the prevalence and pattern of d...

BACKGROUND The foetal aortic Doppler frequency spectrum is influenced by cardiac output and contractility of the foetal heart as well as vascular compliance, blood viscosity and impedance of the arterial vascular system. The present study aimed at comparing Doppler flow pulsatility (PI) and resistance (RI) indexes of foetal proximal descending aorta (AoF) in the first, second and third trimeste...

Abstract Consider a compact surface of genus $\geq 2$ equipped with metric that is flat everywhere except at finitely many cone points angles greater than $2\pi $. Following the technique in work Burns, Climenhaga, Fisher, and Thompson, we prove sufficiently regular potential functions have unique equilibrium states if singular set does not support full pressure. Moreover, show pressure gap hol...
