We demonstrate strong evidence of shape-dependent efficient resonance energy transfer between CdS quantum dots (QDs) and quantum rods (QRs) (donor) to Nile Red dye (acceptor). We also report a simple solution-based method for the preparation of high quality CdS QDs and CdS QRs at relatively low temperature. The observed quenching of PL intensities are 78.8 % and 63.8 % for CdS QDs and QRs, resp...

For the discretization of integral fractional Laplacian $(-\Delta )^s$, $0 < s 1$, based on piecewise linear functions, we present and analyze a reliable weighted residual posteriori error estimator. In order to compensate for lack $L^2$-regularity in regime $3/4 this estimator includes as an additional weight power distance from mesh skeleton. We prove optimal convergence rates $h$-adaptive al...

Let G be a strongly connected, weighted directed graph. We define a product distance η(i, j) for pairs i, j of vertices and form the corresponding product distance matrix. We obtain a formula for the determinant and the inverse of the product distance matrix. The edge orientation matrix of a directed tree is defined and a formula for its determinant and its inverse, when it exists, is obtained....

1 ABSTRACT The location of High Intensity Focused Ultrasound (HIFU) beam in a tissue medium is an important parameter in assessment of the thermal field as it influences the temperature rise in the tissue. Our hypothesis is that the location of the beam can be affected by the power of the transducer. HIFU procedure with 30s of sonication time was performed at different powers of transducer (5 t...

The amount of rainfall that occurs can affect natural disasters and even food production to economic activities. the factor area where rain is one main parameters for how change occurs. So, it necessary have a prediction approach aims find out when what type will occur. Spatial classification interpolation are two methods used make predictions. Random Forest method be predict rainfall. Inverse ...

The purpose of this study is to improve the aerodynamic performance of wind turbine blades, using the Ball-Spine inverse design method. The inverse design goal is to calculate a geometry corresponds to a given pressure distribution on its boundaries. By calculating the difference between the current and target pressure distributions, geometric boundaries are modified so that the pressure di...
