This article presents the exact closed-form solution for a new planar lens, hereinafter referred to as reflecting Luneburg lens (RLL). The proposed structure consists of two stacked parallel-plate waveguides circular shape. rays generated by point source located at periphery bottom waveguide propagate along curvilinear paths, whose trajectories result from variable refractive index profile with...

Cardiovascular parameters are most often assessed at rest, and in many cases in the supine position. This generally facilitates measurement procedures and obviates the need to account for external and usually complex confounding factors, other than those related to the inherent physiology being investigated. Although the supine resting position may be relevant for some part of circadian living,...

JULY/AUGUST 2016 | IEEE SOFTWARE 5 MONITORING ROADWORK quality differs completely from actually building roads. When the road is being built, you take samples of materials and test them in a lab. When it’s ready, you use specialized equipment to look for slippery or uneven pavements. And when the road is opened to traf c, you set up cameras and other sensors to see how it’s used. In software en...

We describe our experience with SILK, a Scheme dialect written in Java. SILK grazes symbiotically on Java’s reflective layer, enriching itself with Java’s classes and their behavior. This is done with three procedures. (constructor) and (method)provide access to a specific Java constructor or method respectively. (import) allows the entire behavior of a class to be imported easily. (import) con...

In N = 4 super Yang-Mills spin chain, we compute reflection amplitudes of magnon bound-state off giant graviton. We first compute the reflection amplitude off Y = 0 brane boundary and compare it with the scattering amplitude between two magnon bound-states in the bulk. We find that analytic structure of the two amplitudes are intimately related each other: the boundary reflection amplitude is a...

We construct a subset A of the unit disc with the following properties. (i) The set A is the finite union of disjoint line segments. (ii) The shadow of A is arbitrarily close to the shadow of the unit disc in “most” directions. (iii) If the line segments are considered to be mirrors reflecting light according to the classical law of specular reflection then most light rays hitting the set emerg...
