The nonlinear optical properties of carbon nanotubes (CNTs) have been studied by using the Z-scan technique. Experiments are performed by CW second harmonic of Nd-YAG laser at 532 nm wavelength with a power of 40 mW. The samples are synthesized by the chemical vapor deposition (CVD) method in the presence of Nickel and Nickel-Cobalt catalysts. In this work, for the first time, effect of the typ...

Assessing an individual's ability to perform effectively, efficiently performing social skills, and social roles in order to enhance the feeling of security as a matter of empowering quality of life can lead to the necessary correlation between social health and a feeling of Security. The purpose of this study is to investigate the significant structural relationship of variables at the level o...

This article is on the simultaneous diffusion approximation and homogenization of the linear Boltzmann equation when both the mean free path ε and the heterogeneity length scale η vanish. No periodicity assumption is made on the scattering coefficient of the background material. There is an assumption made on the heterogeneity length scale η that it scales as ε for β ∈ (0,∞). In one space dimen...

OBJECTIVE To examine the association between the experience of patient-centred care (PCC), health behaviours and cardiovascular disease (CVD) risk factor levels among people with type 2 diabetes. DESIGN Population-based prospective cohort study. SETTING 34 general practices in East Anglia, UK, delivering organised diabetes care. PARTICIPANTS 478 patients recently diagnosed with type 2 dia...

In a previous article (see [BFM]) the authors studied a model of nonlinear membrane where the external surface loading induces a density of bending moment. Due to the special form of the applied surface forces, the emerging Cosserat vector, result of the 3D-2D dimension reduction, was restricted to a class of two dimensional functions. In this paper we analyze the more general case where the Co...

I will described a nonparametric framework for locally adaptive signal processing and analysis. This framework is based upon the notion of Kernel Regression which we generalize to adapt to local characteristics of the given data, resulting in descriptors which take into account both the spatial density of the samples (”the geometry”), and the actual values of those samples (”the radiometry”). T...

The development and encroachment of high technology, from transportation, computation to information is based on the availability of materials in the form of single crystals. With progress in crystal growth technology and characterization, organic, inorganic, semiorganic and organometallic materials having attractive nonlinear optical (NLO) properties are being discovered at rapid rate. NLO mat...
