In this paper Raman spectroscopy is performed on silicone rubber housing materials that have been taken from 200 kV and 400 kV transmission line insulators, located in the Gulf region. The service areas of these insulators feature heavy depositions of sands and dusts yet with intermittent durations of fog and wetting on the surface. In addition, the creepage distances have been selected for heavily...
Aero engine is a kind of sophisticated and expensive industrial product. Accurate fault location and Remaining Useful Life (RUL) estimation for aero engine can lead to appropriate maintenance actions to avoid catastrophic failures and minimize economic losses. The aim of this paper is to propose utilizing Long Short-Term Memory (LSTM) neural network to get good diagnosis and prediction performance...
Aiming at the range ambiguity problem of radar for near space hypersonic target, the existing track before detect (TBD) algorithm cannot detect the target effectively through the long time accumulation, a kind of Hough transform (HT) TBD (HT-TBD) algorithm based on multiple frequency and multiple hypotheses is proposed. Firstly, several pulse repetition frequencies (PRF) are worked alternately to...
Currently, Tengzhou factory has accumulated lots of historical data. However, all kinds of tobacco business data collected separately stored in kinds of systems which cannot be effectively application and analysis, the value of data was not fully exert. In this paper, we proposed the concept which building data center in the basis of data warehouse, while using data mining techniques for all business...
This study used a structural equation model to investigate the relationship between teachers' ICT competency and the usage of ICT in teaching practice. We constructed the research instrument mainly based on the standard of teacher's ability of applying ICT in elementary and secondary schools published by the Chinese MOE. The survey method was used to collect the data from 414 elementary and secondary...
Atmospheric pressure plasma-enhanced chemical vapor deposition (AP-PECVD) was applied for the fabrication of amorphous indium gallium zinc oxide thin-film transistors (a-IGZO TFTs). In this work, a-IGZO TFTs fabricated by AP-PECVD technique were firstly treated by post deposition of in-situ Ar/H2 plasma with atmospheric pressure plasma Jet (APPJ). Compared to without plasma treatment, samples with...
In response to the open-door economic policy of China, companies in Taiwan have gradually relocated their production lines to China in order to decrease production costs and meet major market needs. Moreover, previous studies have examined whether businesses can continually earn excess profits by researching and developing new technology or products using their strong human resources. Therefore, the...
The Pub/Sub, short for Publish-Subscribe, is a flexible mechanism perferred by many users who'd like to passively know the changes of situation. Once a new message is published by a provider, all the subscribers to the specific kind of messages will receive the message and make corresponding responses. In agricultural crop monitoring, such mechanism is very helpful in enhancing the efficiency of message...
Lyme disease is a tick-borne zoonosis caused by the spirochete bacterium which is usually transmitted through the bite of infected ticks. Lyme disease in humans has become the most prevalent vector borne disease in the U.S. where more than 25,000 new cases are reported yearly. It is important to expose the distribution variation pattern and developing trend of the disease in the area for prediction...
Remote sensing derived NDVI data is fundamental to crop monitoring and crop yield estimation research. The usefulness of NDVI relies on reducing noise caused by varying atmospheric conditions such as cloud, haze, and dust as well as by sensor viewing geometry. Different techniques have been applied for noise reduction of composite NDVI products. However, the noise reduction for daily NDVI remains...
The timely retrieval of remote sensing imagery by farmers and decision makers is very important for current agricultural activities. Through the various kinds of imageries of agricultural fields, people can conclude the status of the fields and figure out what kind of crops are suitable and how to cultivate and irrigate the fields. This paper demonstrates how to take advantage of open web service...
In previous studies, the correlation between the vegetation index and meteorological factors were investigated with in intervals defined by the day-of-year. Compared with the day-of-year, the accumulated growing degree days (AGDD) more effectively reflect vegetation growing stage, which serves as important references in agricultural management and disaster prediction. From this end, it is also worth...
WOFOST (WOrld FOod STudies) is a well-known, widely applied simulation model to analyze quantitatively the growth and production annual field crops that was originally developed for crops in European countries. It is the base model for Monitoring Agricultural ResourceS (MARS) Crop Growth Monitoring System (CGMS) in operational use for yield estimation in European Union. The model is of great potential...
Flood is defined as water that temporarily submerges land. In the United States, flood is being considered as an event only if it last over 72 hours, but the time frame is much longer in the Europe. The information of water bodies is an important source when examining floods. However, this data is not always available or accurate by traditional survey since water surface changes frequently. Remote...
Characterized by features of standards-based, platform-independent, portable, self-describing, and compact, GeoPackage, a new open format for geospatial information container, makes it much easier to manipulate geospatial data on mobile devices such as smartphones and tablets. In this paper, we present a GeoPackage based mobile application implementing Common Map API on both Google MapsTM and OpenLayers...
GeoPackage, an open format for geospatial information, provides a gateway to bridge agricultural geographic information and mobile devices such as smartphones and tablets. In this paper, we present a Cordova framework based GeoPackage mobile application to support field operations in agriculture. By implementing GeoPackage SDK on mobile application, GeoPackage files can be easily accessed, managed,...
The initial weights and thresholds of BP neural network are optimized by genetic algorithm in advance, and then the BP neural network is used in the prediction model of the postgraduate entrance examination results. Experimental results show that the optimized prediction model due to overcome the slow convergence speed and the defects of easy to produce local minimum has better accuracy than prediction...
Chromatography has been widely used in discrimination and quality control for Chinese medicines (CMs). Nevertheless, regular analytical approaches are not applicable if training samples are small while features are large. Support vector machine (SVM) with recursive feature elimination algorithm (RFE-SVM) is presented in this study for discrimination of Pericarpium Citri Reticulatae through small chromatographic...
In recent years, more and more people are learning Chinese calligraphy, and for how to correctly brush pen and brush, the less people know about this. This topic combines the spatial point cloud data and gesture recognition technology, in view of the common brush pen gestures — five fingers penned method for the study of feature selection and extraction. Innovation point of this article is the gesture...
This work investigates the effects of GO RRAM w/ and w/o boron doping, and the effects of thermal annealing. From the experiment results, the B-doped GO RRAM annealed at 350°C shows the best performance with a higher resistance ratio of 4.15 orders and a higher dc switching cycles of 1300.
