Key words: brachytherapy, dose calculation, heterogeneities, collapsed cone, Monte Carlo I. INTRODUCTION The potential to improve the accuracy of the calculated dose is commonly ignored in brachytherapy treatment planning, despite the fact that threedimensional 3D imaging is used for localization and, hence, also provides the necessary ge

or constraint cone moves off the limb of the body that the instrument is observing. Thankfully, many of these calculations can be simplified to the same problem: the intersection of two or more convex cones. Here we describe an efficient algorithm that can be used to find the intersection of two or more convex cones in free space.

Eccentric Cone – a manhole cone designed and manufactured with the entry to the cone offset to the side, creating a straight vertical wall on one side. These cones are generally considered to allow safer ingress. These cones allow greatest flexibility in placement of the lid due to the ability of the

To convert between radiometric and photometric units, one needs to know the photopicspectral luminous efficiency curve V( ), which gives the spectral response of the human eye to various wavelengths of light. The original curve, which is shown earlier, was adopted by the Commission on Illumination (CIE)

The nose cone The nose cone needs to be slightly pointed, and as we'll see in Section 4, it's also important to have a little bit of weight towards the front of the rocket. My favourite way of achieving both these aims is simply to tape a tennis ball to the end of the bottle. This might not look quite as aerodynamic as you

The solution is cone valve IBC blending. A cone valve IBC is known to discharge powders without rolling effects, by 'holding back' the batch in the centre and promoting the flow from the sides of the IBC. In other words, 'mass flow' rather than 'funnel flow'. This way, the blend uniformity is maintained

Similarly, since circles beat polygons, cones are better than any other pyramid. For the same reason, cylinders are better than any other prism. Overall, however, the sphere is the most efficient 3D shape. If we directly compare these four common shapes for a fixed volume of 1 𝑖, we get: Cube* 𝑉 H=1000 I3 Best Cone* (ℎ=3 N)

The calculated dish efficiency with this helix as a feed is very good, about 77%, at a center frequency of GHz, with best f/D around, just about right for an offsetfed dish. Thus, we might expect a real efficiency >60% feeding a reasonably sized (>10λ) offset dish.
