The computer modeling is carried out for parameter of sensitivity of optoelectronic chemical and biosensors, using phenomena of surface plasmon resonance (SPR). The physical model of SPR-sensor’s is described with (or without) of modifications of sensitive gold film surface by a dielectric layer. The variants of increasing of sensitivity for SPR-biosensors, constructed on the principle gold – d...

Free surface modeling plays an important role in some ocean structures design, especially in Oscillating Water Column (OWC) devices. Boundary element method (BEM) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. In this paper, BEM was used for free surface modeling in OWC chamber and out of it. Linear kinematic and dynamic bo...

A package characterization technique using coplanar waveguide (CPW) probes and line–reflect–match (LRM) calibrations for surface-mountable packages is presented. CPWto-package adapters (CPA) are fabricated on alumina substrates to mount and measure the high-frequency response of plastic packages. Offset CPA standards in conjunction with an LRM calibration are used to de-embed the response of th...

introduction: occurrence of landslides depends on several factors such as the composition and structure of earth materials, rainfall level, temperature, groundwater regime and cover crops. landslides are a main natural hazard in iran, because of its special geological conditions and its mountainous active tectonic regime. linear civil structures, such as roads, highways and railways, face serio...

Abstract Polynomial Regression Surface (PRS) is a commonly used surrogate model for its simplicity, good interpretability, and computational efficiency. The performance of PRS largely dependent on basis functions. With limited samples, how to correctly select functions remains challenging problem. To improve prediction accuracy, modeling approach based multitask optimization ensemble (PRS-MOEM)...
