In this paper, we investigated UPT avoidance problem with multiple multimedia flows. We propose a management module, called Unintelligible Flow Management (UFM), to enhance UPTA in networks with multiple multimedia flows. We have proposed two different management policies for UFM, i.e. Random Select (RS) and Least Bandwidth Select (LBS). We have demonstrated incorporation of RS/LBS into WFQ, an...
The scalar wave inverse source problem (ISP) of determining an unknown radiating source from knowledge of the field it generates outside its region of localization is investigated for the case in which the source is embedded in a non-homogeneous medium with known index of refraction profile n(r). It is shown that the solution to the ISP having minimum energy (socalled minimum energy source) can...
Finite-difference time-domain numerical experiments and supporting analyses demonstrate that the spectral dependence of the total scattering cross sections of randomly inhomogeneous dielectric spheres of sizes in the resonant range closely resemble those of their homogeneous counterparts that have a volume-averaged refractive index. This result holds even for the extreme case in which the refra...
We study the relationship between the period and the index of a principal homogeneous space over an abelian variety, obtaining results which generalize work of Cassels and Lichtenbaum on curves of genus one. In addition, we show that the p-torsion in the Shafarevich-Tate group of a fixed abelian variety over a number field k grows arbitarily large when considered over field extensions l/k of bo...
PURPOSE It may be possible to restore accommodation to presbyopic human eyes by refilling the lens capsular bag with a soft polymer. In the present study, optical changes were measured that occurred in a pig eye model after the refilling of the capsular bag. METHODS The optical power and spherical aberration in 10 isolated pig lenses were measured under different conditions. They were first d...
We discuss when homogeneous quasipositive links are positive. In particular, we show that a diagram of link whose number Seifert circles is equal to the braid index positive diagram.
fundamental quantities in nature, underlies many of the basic properties of the universe. The velocity of a pulse of light propagating in any medium (homogeneous or inhomogeneous) is determined by the group index ng , a magnitude which should not be confused with the refractive index of the medium. The group velocity, given by vg=c /ng , where c is the speed of light in vacuum, is determined no...
We review the potential limitations of the two current methodologies for evaluating the duration of action of antihypertensive therapy: the smoothness index (SI) and the trough : peak ratio (TP). We propose a simple correction factor for the SI. The correction factor prevents the SI from reaching erroneous high values in situations in which the reduction in blood pressure (BP) is inadequate but...
the vertex-edge wiener index of a simple connected graph g is defined as the sum of distances between vertices and edges of g. two possible distances d_1(u,e|g) and d_2(u,e|g) between a vertex u and an edge e of g were considered in the literature and according to them, the corresponding vertex-edge wiener indices w_{ve_1}(g) and w_{ve_2}(g) were introduced. in this paper, we present exact form...
study of the potential fields at different altitudes, constituting a multiscale field is a class of interpretative methods which are used to approximate depth and geometry of sources. interpretation of potential fields by this class of methods is mainly based on the recognition that the gravity or magnetic fields, generated by ideal sources (point mass, line of mass, sheet and contact) are homo...
