As an example of using of the approach we consider technological process to manufacture more compact double base heterobipolar transistor.

This paper presents a modified time discontinuous Galerkin finite element method (MDGFEM) for transient acoustic wave propagation problem of multilayered pavement.

The well-known generalized Biot’s theory is employed to describe the wave propagation problem.

Stress functions are introduced in various rectangular regions and the continuity of tractions are enforced across all inter-region boundaries. Furthermore, continuity of displacements is enforced across the junction of the two segments of the base laminate. The analysis

Multilayer thin films prepared from weak polyelectrolytes can exhibit a rich suite of anomalous physicochemical properties. One of the major factors that influence the properties of such films is the acid/base chemistry of the weak functional groups of the poly- electrolytes. In fact, the apparent dissociation constants of weak polyelectrolytes can shift by as much as 1–4 pH units upon incorporation into multilayer films from that in dilute solution. Here, we discuss this variability in the dissociation behavior of polyelectrolytes in multilayer films, and how it relates to understanding the d

The base dielectrics of commercial LTCC systems have a τf in the range of −50 ppm/°C to −80 ppm/°C.

This article shows that international multilayer market segmentation of civil helicopters is the base marketing concept for the company, which develops and produces civil helicopters. Implementation of the concept would likely assist the Russian helicopters’ markets widening, own production development and technological update.

Abstract:

The shift from fossil-based packaging materials to more sustainable alternatives is driven by evolving environmental regulations aiming for enhanced recyclability and biodegradability. Dispersion coatings, as opposed to extrusion-based approaches, offer significant advantages by reducing the coat weights, but generally, multiple coating layers are needed to meet functional performance requirements. This study explores the application of upscaled multilayer dispersion coatings comprising polylactic acid-based coating (PLAX) and hybrid nanomaterial lacquer (bioORMOCER®) on commercial base papers

Abstract:

The pystacked command implements stacked generalization (Wolpert, 1992, Neural Networks 5: 241–259) for regression and binary classification via Python’s scikit-learn. Stacking combines multiple supervised machine learners—the “base” or “level-0” learners—into one learner. The currently supported base learners include regularized regression, random forest, gradient boosted trees, support vector machines, and feed-forward neural nets (multilayer perceptron). pystacked can also be used as a “regular” machine learning program to fit one base learner and thus provides an easy-to-use application pr

Abstract:

Semi-rigid layer is widely used as the base in China. However, the structure has resulted in many premature distresses in asphalt concrete layer. In order to overcome the problem, the composite base is introduced which is composed by both flexible and chemically stabilized material. The internal stresses are calculated by linear multilayer elastic theory and then, a comparison of the stresses of asphalt pavement with semi-rigid base and composite base is provided. The result shows that the composite base composed by all, consisting of the asphalt treated layer, graded crushed stone and cement

Abstract:

Transient liquid-phase(TLP) bonding of SiC particle reinforced aluminum matrix composite(SiCp/Al MMCs) ,using Cu film, Cu foil, Ni foil and Cu/Ni/Cu multilayer foil interlayer, was investigated. The effect of surface status, interlayer species and bolding time on bonding microstructure and properties were also estimated by metallographic microscope, scanning electron microscopy (SEM), X ray diffraction and tensile testing machine. The results show that adding holding time can improve shear strength of joint. Better strength of joint can be obtained due to without the effect of oxide with Cu fi

Abstract:

The creation of a multilevel system of interconnections in submicron integrated circuits makes it possible to reduce the electrical resistance of conductive tracks, parasitic capacitance between conductors, and increase the speed of microelectronic devices. It is proposed to form a transverse profile of the current-carrying tracks of a multilayer metallization system in the form of an isosceles trapezoid with angles at the lower base equal to 75–85 degrees. Etching of an aluminum-based alloy film is carried out in a plasma gas mixture of BCl3, Cl2, and N2 at the pressure of 150–250 mTorr and p

The work shows the role of hidden neurons in the multilayer feed-forward neural networks. The numeric expression of hidden neurons is usually determined in each case empirically. The methodology for determining the number of hidden neurons are described. The neural network based approach is analyzed using a multilayer feed-forward network with backpropagation learning algorithm. We have presented neural network implementation possibility in bankruptcy prediction (the experiments have been performed in the Matlab environment). On the base of bankruptcy data analysis the effect of hidden neurons

Abstract Background The use of vascularized flap to reconstruct the skull base defects has dramatically changed the postoperative cerebrospinal fluid (CSF) leak rates allowing the expansion of endoscopic skull base procedures. At present, there is insufficient scientific evidence to permit identification of the optimal reconstruction technique after the endoscopic endonasal approach (EEA). Objective The main purpose of this article is to establish the risk factors for failure in the reconstruction after EEA and whether the use of a surgical reconstruction protocol can improve the surgical resu

The mechanical and wear behavior of CrN/CrAlN multilayers were improved by tailoring the experimental conditions of a hybrid magnetron sputtering process based on a high-power impulse (HiPIMS) and two direct current magnetron sputtering (dcMS) power supplies. To this end, the influence of the base layer and of the combination of Cr and CrAl targets, which were switched to the dcMS and HiPIMS power supplies in different configurations, were investigated with respect to the growth of ceramic CrN/CrAlN multilayers onto commercial gas-nitrided diesel piston rings.

Electronic devices are high-demand commodities in today’s world, and such devices will continue increasing in popularity. Currently, batteries are implemented to provide power to these devices; however, the need for battery replacement, their cost, and the waste associated with battery disposal present a need for advances in self-powered technology. Energy harvesting technology has great potential to alleviate the drawbacks of batteries. In this work, a novel piezoelectret foam material is investigated for low-level vibration energy harvesting. Specifically, piezoelectret foam assembled in a m

Aim/Purpose: This paper describes how to use a multilayer perceptron to improve concept drift recovery in streaming environments. Background: Classifying instances in a data stream environment with concept drift is a challenging topic. The base learner must be adapted online to the current data. Several data mining algorithms have been adapted/used to this type of environment. In this study, two techniques are used to speed up the adaptation of an artificial neural network to the current data, increasing its predictive accuracy while detecting the concept drift sooner.

In order to solve the problem that existing visible and infrared image fusion methods rely only on the original local or global information representation, which has the problem of edge blurring and non-protrusion of salient targets, this paper proposes a layered fusion method based on channel attention mechanism and improved Generative Adversarial Network (HFCA_GAN). Firstly, the infrared image and visible image are decomposed into a base layer and fine layer, respectively, by a guiding filter. Secondly, the visible light base layer is fused with the infrared image base layer by histogram map
