In his 1985 article (“Projection pursuit”), Huber demonstrates the interest of his method to estimate a density from a data set in a simple given case. He considers the factorization of density through a Gaussian component and some residual density. Huber’s work is based on maximizing Kullback–Leibler divergence. Our proposal leads to a new algorithm. Furthermore, we will also consider the case...

This paper describes a model for the analysis of multilayered chiral structures containing planar electric and magnetic scattering elements of arbitrary shape, illuminated by an elliptically polarized plane wave. The particular case of a single chiral layer is analyzed and the scattering matrices for single and dual electric and/or magnetic dipole distributions are derived in an original way. A...

To explore the anti-penetration performance of specially shaped ceramic/metal composite armor, such an armor is designed and fabricated using a semi-cylindrical projectile resistant ceramic metal back plate, its for 12.7 mm armor-piercing incendiary (API) (also known as 0.50 caliber API projectile) investigated experimentally numerically. The results show that due to significant attitude deflec...

This paper summarizes Kormendy et al. (2009, ApJS, in press, arXiv:0810.1681). We confirm that spheroidal galaxies have fundamental plane correlations that are almost perpendicular to those for bulges and ellipticals. Spheroidals are not dwarf ellipticals. They are structurally similar to late-type galaxies. We suggest that they are defunct (“red and dead”) late-type galaxies transformed by a v...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

Zone plates are high quality optics that have the potential to provide diffraction-limited nano-focusing of hard X-ray free electron laser radiation. The present publication investigates theoretically the temperature behavior of metal zone plates on a diamond substrate irradiated by 0.1 nm X-rays from the European X-ray Free Electron Laser. The heat transfer in the optic is simulated by solving...

In this study, the heat transfer characteristics of flat plate collectors with circular and elliptical serpentine tubes are theoretically analyzed compared in terms m˙, Re, Nu, hfi, FR, Qu, μTh under various water flow rates standard test conditions. The results reveal that maximum correspondence to design 56% turbulent flow, minimum 47% for cross-section laminar flow. addition, it was found hi...

In order to study the influence of nano-clay on crack resistance cement-based materials, two kinds nano-metakaolin (NMK) and nano-attapulgite clay (NMA) were considered. The early cracking process mechanical properties cement mortar (NCM) was studied by using a plate knife-edge constraint test. Based fractal theory, distribution characteristics NCM surface cracks revealed, calculation method fo...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...
