Anti-reflection coatings (ARC) of dielectrics help in balancing the refractive index mismatch between silicon and air as result reducing the reflection losses but they do not cause bending of light rays which is essential for efficient light trapping of the injected light into the cell. Texturiaztion helps in both the reduction of reflection losses and light trapping due to bending of the light...

Discovery of the CP-violation in the lepton sector is one of the challenges of the particle physics. We search for possible principles, symmetries and phenomenological relations that can lead to particular values of the CP-violating Dirac phase, δ. In this connection we discuss two extreme cases: the zero phase, δ = 0, and the maximal CP-violation, δ = ±π/2, and relate them to the peculiar patt...

Previous studies have demonstrated the existence of optimization criteria in the design and development of mammalians cardiovascular systems. Similarities in mammalian arterial wave reflection suggest there are certain design criteria for the optimization of arterial wave dynamics. Inspired by these natural optimization criteria, we investigated the feasibility of optimizing the aortic waves by...

The bidirectional reflectance distribution function (BRDF) formalism is commonly used in computer graphics to represent surface reflection properties. Although many BRDF models have been proposed, most do not possess at least some of the desirable practical properties. In this paper we present a simple and flexible model which satisfies many of these requirements. We show that the proposed mode...

After the development of a very common formalism for neutron three beam cases, a detailed investigation is given for the case (111, 111/220) and a comparisation with the (different) case (111, 111/200) is presented. It is shown that the former case behaves different by concerning dispersion branches and reflection curves; both are asymmetric in respect to a wave incident in the exact Bragg dire...

We present an exact operator quantization of the Euclidean Black Hole CFT using a recently established free field parametrization of the fundamental fields of the classical theory [4, 5, 6, 7]. Quantizing the map to free fields, we show that the resulting quantum fields are causal and transform as covariant fields w.r.t. the Virasoro algebra. We construct the reflection operator of the quantum ...

In this work, the claim that optically thick gases can emit as blackbodies is refuted. The belief that such behavior exists results from an improper consideration of heat transfer and reflection. When heat is injected into a gas, the energy is primarily redistributed into translational degrees of freedom and is not used to drive emission. The average kinetic energy of the particles in the syste...

A method is presented for determining the scaled optical thickness of clouds from reflected solar radiation measurements. The procedure compares measurements of the reflection function with asymptotic expressions for the reflection function of optically thick layers. Analytic formulas are derived which explicitly show the dependence of the retlection and transmission functions of nonabsorbing a...

Due to Increasing demands of cartoon style In many areas of computer graphic aspects, this paper presents a simple stylized shading technique to enhance the cartoonlsh appearance In two aspects. First, a new toon-illumlnation model Is developed to emphasize the boundaries between diffuse reflection part and specular reflection part in the phong illumination model. The new discrete shading will ...

We find 26 reflections in the automorphism group of the the Lorentzian Leech lattice L over Z[e2πi/3] that form the Coxeter diagram seen in the presentation of the bimonster. We prove that these 26 reflections generate the automorphism group of L. We find evidence that these reflections behave like the simple roots and the vector fixed by the diagram automorphisms behaves like the Weyl vector f...
