Until now the representation (i.e. plotting) of curve in Parallel Coordinates is constructed from the point ↔ line duality. The result is a " line-curve " which is seen as the envelope of it's tangents. Usually this gives an unclear image and is at the heart of the " over-plotting " problem; a barrier in the effective use of Parallel Coordinates. This problem is overcome by a transformation whi...

background: monte carlo determination of tg-43 brachytherapy dosimetry parameters and dose distribution calculation for 131cs source model cs-1 are presented in this study. materials and methods: the dose distribution was calculated around the 131cs model cs-1 located in the center of 30 cm ×30 cm ×30 cm water, and soft tissue phantoms cube using mcnp code by monte carlo method. the percentage ...

The usefulness of the Craig counter-current distribution technique (1, 2) for studying the purity of compounds and the metabolic fate of therapeutic agents can be augmented by deriving the theoretical distribution values from the “Tables of the binomial probability distribution” (3). By use of such tables, which only recently have become generally available, laborious calculation of theoretical...

This paper compares the performance and efficiency of different function range interval methods for plotting f(x, y) = 0 on a rectangular region based on a subdivision scheme, where f(x, y) is a polynomial. The solution of this problem has many applications in CAGD. The methods considered are interval arithmetic methods (using the power basis, Bernstein basis, Horner form and centred form), aff...

1. Rat liver glycogen was separated into fractions of relatively uniform particle sizes by large volume rate-zonal centrifugation of tissue homogenates with the use of sucrose density gradients. 2. After centrifugation, the distribution curve obtained by plotting the glycogen content of all collected fractions exhibited its maximum a short centrifugal distance from the zone which contained the ...

Intrusion of the Kalaybar nepheline syenite into the Cretaceous pelitic and calcareous sediments has produced a thermal aureole up to 1km thick. Six mineralogical zones are developed in the pelitic rocks with minerals such as cordierite, K feldspar, sillimanite and corundum. Chemically suitable rocks are partially melted in response to the heat from the pluton. Five mineralogical zones are deve...

It is well known that the propagation of Lamb waves in elastic solid medias depends on frequency and material properties, but it does not depend direction isotropic gives rise to two basic types modes, symmetric antisymmetric ones. This paper presents an application semi-analytical finite element (SAFE) method aluminum plate thickness e = 2mm . The main goal this make a quantitative evaluation ...

the monte carlo method can be used to describe any technique that approximates solutions to quantitative problems through statistical sampling. this method is considered to be the most accurate method for dose calculation in radiotherapy. for complete modeling of a linear accelerator, it is required that the manufactured information covers all data, but some data such as primary electron energy...

Ventricular function curves were constructed in 39 patients having coronary arteriography by plotting left ventricular end-diastolic pressure and stroke work index before, during, and immediately after atrial pacing. Similar curves were constructed from measurements obtained before and 3 minutes after a standard left ventricular angiogram. Both methods vary preload sufficiently to produce detec...
