Photonic crystals based on graphene plasmons (GPs) are highly tunable and can accurately control photonic transmission at the nanoscales. In this work, transfer matrix method (TMM) is introduced to study plasmonic crystal (GPC) with periodic surface conductivity in case of normal incidence. The introduction TMM after considering abnormal phase scattering abrupt interface gives an idea manipulat...
In this article, we considered the field analysis in photonic crystal Bragg fibers. We apply the method of transmission matrix to calculater the dispersion curves, the longitudinal wave number over wave number versus incident wavelength, and the field distributions of TE and TM modes in the Bragg fiber. Our analysis shows that the field of guided modes is confined in the core and can exist onl...
بهمنظور مدل سازی فضایی یک متغیر ناحیهای در یک منطقه یا سایت، ابزارهای درونیابی و برآوردگرهای متفاوتی مورد استفاده قرار میگیرد. در این پژوهش، روش درونیابی نوینی با استفاده از تعمیم شبکه تابع پایه شعاعی و با در نظر گرفتن مختصات و ساختار فضایی دادهها ارایه شده است. در این روش، بهمنظور درونیابی، ابتدا ساختار فضایی و ناهمسانگردی دادهها مورد بررسی قرار میگیرد و با رسم واریوگرامهای جهتی، ...
Hidden Markov models (HMM), like chains or trees considered in this paper, are widely used in different situations. Such models, in which the hidden process X is a Markov one, allow one estimating the latter from an observed process Y , which can be seen as a noisy version of X . This is possible once the distribution of X conditional on Y is a Markov distribution. These models have been recent...
Because DNA polymerase cannot replicate telomeric DNA at linear chromosomal ends, eukaryotes have developed specific telomere maintenance mechanisms (TMMs). A major TMM involves specialized reverse transcriptase, telomerase. However, there also exist various telomerase-independent TMMs (TI-TMMs), which can arise both in pathological conditions (such as cancers) and during evolution. The TI-TMM ...
This paper presents a modeling and control of aerostructure developed by lattice-based cellular materials/components. The proposed aerostructure concept leverages a building block strategy for lattice-based components which provide great adaptability to varying flight scenarios, the needs of which are essential for in-flight wing shaping control. A decentralized structural control design is pro...
The Cell Superscalar framework (CellSs), from Barcelona Supercomputing Centre, offers a high-level portable programming model to port, parallelise and tune applications on Cell Broadband Engine. Via implementation of a Jacobi solver and a triple-matrix-multiply (TMM) kernel from a wavelet-based evaluation of Coulomb potentials in molecular systems, using the native programming API of the IBM So...
The presence of immortal cell populations with an up-regulated telomere maintenance mechanism (TMM) is an almost universal characteristic of cancers, whereas normal somatic cells are unable to prevent proliferation-associated telomere shortening and have a limited proliferative potential. TMMs and related aspects of telomere structure and function therefore appear to be ideal targets for the de...
Testing is a critical component of a mature software development process. It is one of the most challenging and costly process activities, and in its fullest definition provides strong support for the production of quality software. In spite of its vital role in software development, existing maturity models have not adequately addressed testing issues nor has the nature of a mature testing pro...
