Background . Noncystic fibrosis bronchiectasis (NCFB) is characterized by airway expansion and recurrent acute exacerbations. Macrolide has been shown to exhibit anti-inflammatory effects in some chronic diseases. Objective To assess the efficacy of roxithromycin on inflammation remodeling patients with NCFB under steady state. Methods The study involved an open-label design 52 eligible Chinese NCFB, who were assigned control (receiving no treatment) 150 mg/day for 6 months) groups. At...

To recognize prohibition traffic sign, this paper proposes a novel method that is trained by small number of samples and uses the feature histogram oriented gradient (HOG) support vector machine (SVM) network. The recognition mainly divided into three stages. first stage image preprocessing, which includes interception based on ellipse detection, resizing, Gamma correction. In part interception, new detection called RHT_MCN proposed RHT, maximum coincidence (MCN) edge points detected to...

Because of the nonlinear characteristics monitoring system in military barracks, traditional KPCA method either have low sensitivity or unable to detect fault quickly and accurately.In order make use higher-order statistics get more useful information meet requirements real-time diagnosis sensitivity, a new detection is proposed based on multivariate statistical kernel principal component analysis (MSKPCA), which combines statistic pattern framework (SPA) (KPCA).First, transformation...

This paper develops a rapid method for discriminating the geographical origins and age of roasted Torreya grandis seeds by near infrared (NIR) spectroscopic analysis pattern recognition. 337 samples were collected from three main producing areas produced in last two years. The objective is to discriminate Fengqiao with protected indication (PGI) those another provinces. Age classification aimed detect old year freshly ones. Partial least squares discriminant (PLSDA) was used develop models,...

With the help of decision theory bad identification which combines historical and remote from IDP (integrated platform) 6 rules are logical judgment conducted, quality evaluation established accordingly. The repairing improves input for state estimation. weighed least-square (WLS)...

The “Apple Teacher” program adopts a mixed learning mode in course teaching, combining network resources with the real environment to form “Online Learning + Teaching Assistant Support; Offline Class Theme Learning; Exchange Discussion Summary Reflection” one of blended modes and “Basic Knowledge—Self-testing—Theme Learning—Self-creation—Summary activities.“The national medium long-term education reform development outline (2010-2020)” since its launch, pays more attention informatization...

The gas–liquid Venturi injector has been widely applied in industrial production due to its advantages of high entrainment and low energy consumption. In this study, Computational Fluid Dynamics (CFD) was employed investigate the effect interface structure within mixing section on behavior by varying geometry during coaxial flow. simulation results indicate that along jet direction, generally transitions from a smooth cylindrical shape lobed section. Surface waves mainly appear region....

Abstract Ocean wave power generation can provide clean energy for offshore electrical equipment. However, the random changes in waves are not conducive to capturing efficiently. How improve capture of has become a problem that equipment needs address. This study uses Hilbert-Huang Transform (HHT) predict frequency and controls motor according predicted frequency, enabling device resonate with obtain maximum power.

<i>Objective</i>: To initially construct a comprehensive assessment system for upper extremity occupational competence based on the International Classification of Functioning, Disability and Health (ICF), to provide reference development intervention programs covering physiology, psychology, function social participation patients with injuries. <i>Methods</i>: Taking ICF core set vocational rehabilitation as basic framework, using Delphi expert correspondence method, after two-round...

The core employees are the key resources of gathering strength and innovating for scientific technological small micro enterprises (STSMEs). Aiming at status quo education training STSMEs, as well solidification current incentive mechanism, unreasonable salary system, imperfect mechanism lack corporate culture, this study starts with influence on analyzes problems existing in model STSMEs. Combined characteristics proposes specific measures to improve stimulate potentials employees, give...

In this work, a color normalization method is shown. Firstly, on the basis of analyzing characteristics traffic sign combination, classification image based demonstrated, and normalized mapping matrix analyzed, target set resolved. Secondly, construction classifier surface segmentation, initially classified, then non-reserved colors realized by using improved K-means clustering algorithm. According to analysis algorithm, improvement proposed analyzed. One self-selection initial centers class...

Through the analysis of three-phase T-type three-level converter and feedforward decoupling control strategy, a mathematical model in d-q coordinate system is established. In order to realize independent active reactive power, double closed-loop strategy current inner loop voltage outer designed, power compensation function realized on basis changing component. Finally, correctness rationality controller parameter design are verified through PLECS simulation.

As a power conversion interface for new energy generation into the grid, grid-connected inverters are more and widely used in modern systems, multiple parallel technology has become one of most mature technologies. When operate parallel, droop control can be to solve problem sharing without relying on communication equipment. In order ensure stability inverter, three factors should considered parameter design control, which drooping outer loop, voltage double closed-loop effects current...
