Ray Trace Notes
A MATLAB function that performs a direct numerical integration to the ray optics equation described in book Section 1.3.2 has been implemented. The code, which was written by Dennis Hancock http:nnwww.dennishancock.com, is embodied in the MATLAB function Launch Rays. The function launches a prescribed bundle of rays from a point on the z axis in a rectangular coordinate reference system. Each r...
متن کاملNotes for Lower Bounds Techniques
Proving lower bounds is often more challenging than proving upper bounds, since one has to defeat all possible methods (or algorithms) rather than showing that one of them works. Indeed, it seems harder to cope with a universal quantifier than with an existential one, but one should bear in mind that a second quantifier of opposite nature follows the first one. That is, a lower bound has the fo...
متن کاملLecture Notes: Comparison-Based Lower Bounds
We have proved in a previous lecture that the permutation problem on n elements requires Ω(min{n, n B logM/B n B}) I/Os to solve in the indivisibility model. This immediately implies the same lower bound for sorting—if we can sort n elements in x I/Os, then we can also permute them in O(x) I/Os. This, in turn, means that no “indivisible” EM algorithm can always sort in o( n B logM/B n B ) I/Os,...
متن کاملNotes on Lower-Bounds for Testing
Recall that we showed that there is an algorithm for testing triangle-freeness of dense graphs that had a dependence on 1/ that was quite high. While we cannot exactly match that dependence with a lower bound, we’ll show that a super-polynomial dependence is necessary. Here we’ll give the proof only for the one-sided error case, and note that it can be extended to two-sided error algorithms. Na...
متن کامل3D Orthodontics - from Verne to Shaw
As children receiving new toys, we are approaching a great new world of fantasy. Three-dimensional image devices arrived at the port of Orthodontics with increasingly strong anchors firmly holding to the ground. In this case, immobility is symbolical and inversely proportional to the ongoing possibilities we are not even capable to imagine. Perhaps, the French novelist Julio Verner could. Where...
