The characteristics of four mainstream protocols including Ethernet/IP, Profinet, EtherCAT and Ethernet Powerlink in industrial field network are analyzed respectively in the paper. According to the different requirements of the on-site production line level control system and the internal network of the automation equipment, it is significant to adopt the appropriate network protocol. In the on-site...
Spatially coupled codes have been shown to achieve the capacity for a large class of channels universally. Many variants of such codes have been introduced to date. We discuss a further such variant that is particularly simple and is determined by a very small number of parameters. More precisely, we consider and ensemble of time-invariant low-density parity-check convolutional codes with very large...
With the rapid development of Internet and multimedia, there is new challenge on streaming media processing and transmission. On one hand, the demand for the quantity and quality of multimedia resources are getting higher, which requires the matching capabilities of data storage and transmission. On the other hand, restricted to the computer's processing power, heterogeneous network environment, network...
Pitch correction with preservation of voice timbre has been a challenging issue that hinders the development of music related applications. To address this problem, we propose a spectral modeling synthesis (SMS) based automatic pitch correction system for singing voice. When obtaining one candidate singing voice, we firstly conduct pitch detection with voiced/unvoiced decision, and extracts the pitch...
The least squares based eigenfilter method has been applied to the design of both finite impulse response (FIR) filters and wideband beamformers successfully. It involves calculating the resultant filter coefficients as the eigenvector of an appropriate Hermitian matrix, and offers lower complexity and less computation time with better numerical stability as compared to the standard least squares...
For scientific management of sewage treatment operation of city, and playing a greater environmental and economic benefits, this paper takes into account the factors such as watershed planning and construction of sewage treatment plant comprehensively, to establish a comprehensive evaluation indicator system for urban sewage treatment. The calculation method of evaluation standard and index is established...
Deep learning has become increasingly popular in both academic and industrial areas in the past years. Various domains including pattern recognition, computer vision, and natural language processing have witnessed the great power of deep networks. However, current studies on deep learning mainly focus on data sets with balanced class labels, while its performance on imbalanced data is not well examined...
The winter crop planting can bring increased income for peasants, but also improve the soil quality by rotation system. So, the planting area monitoring remote sensing of winter crops have been an important work for agriculture planting structure statistic, management and decision in south China. At present the cloudy and rainy weather is a very serious issue for remote sensing of winter crops in...
Operational ocean observing system (OOOS) can meet the needs of marine disaster prevention and reduction, safeguard socio-economic development in coastal zones, and promote marine resource exploitation. As a solid foundation for the establishment of the OOOS, operational ocean observing equipment (OOOE) is attached great significance across the world. Three kinds of OOOEs in China are introduced and...
Partial discharge (PD) site in high voltage power equipment can be located by solving the time difference equations. Estimating the time difference between PD signals with high accuracy is of great importance for accurate locating. This paper presents a time difference determining algorithm using cumulative energy function and differential energy method. The differential energy characterize the increase...
This paper introduces a novel tree induction algorithm called sequential Random Forest (sRF) to improve the detection accuracy of a standard Random Forest classifier. Observations have shown that the overall performance of a forest is strongly influenced by the number of training samples. The main idea is to sequentially adapt the number of training samples per class so that each tree better complements...
Most of the time people stay in the indoor environment, so Taiwan government established indoor air quality (IAQ) regulations to protect public health and the living environment. This study defined fuzzy sets and fuzzy rules according to the national IAQ and standard ANSI/ASHRAE 55–1992. The fuzzy controller determine the operation time of air conditioner and exhaust fan to meet the national IAQ regulations...
Depth Image Based Rendering (DIBR) is a well-known process for producing 3D views, which can synthesize a virtual view from images and their associated depth information. However, in an image owing to the abrupt change of the scene, the depth image may change rapidly to make the converting view have holes with different sizes and directions, and subsequently it affects qualities of the 3D view and...
In mechanical product design, designers usually reuse a large number of standard parts and commonly used typical structures accumulated in long-term industry design practice. In this paper, a flexible part library system is proposed to promote the flexibility of PLS. The system uses a flexible part information presentation and User dynamic interface to realize the parameter diversity, and can adapt...
Accurate estimation of noise level is of fundamental interest in a wide variety of vision and image processing applications as it is critical to the processing techniques that follow. In this paper, a new, effective noise level estimation method is proposed based on the study of singular values of noise-corrupted images. There are two major novel aspects of this work to address the major challenges...
Joint Capabilities Integration and Development System is the system for U.S. Army to define potential operational capability gaps or technical opportunities, i.e., the system for demonstration of operational capability requirements. With view to regulate the operational capability requirements demonstration and enhance the standard and quality of demonstration, U.S. Army has issued 6 editions of Joint...
Abstract: In view of using symmetrical normalization for smaller deviation than standard normalization for the multi-tau photon correlator in the whole delay time range but need more monitor channels. We suggest employing symmetrical normalization when the lag time larger than 16384 and standard normalization smaller than 16384. Deviation of symmetrical normalization and standard normalization was...
We persent a new method for performing bands secelction exptements with 16 narrow-bands multispectal images data of cucumber. This method allows for the visual inspection base on the brightness value of the images which achieve standard assessment during visual wavelength region. It follows a standard feature selection approach in which correlative coefficient measure is used as a figure of merit...
Green Security Barrier is a non-tariff barriers in currently international trade which is applied by more and more developed countries to comply with, the barriers are in compliance with relevant national trade agreement and nominal reason is reasonable, especially China has been accession to the WTO, and unable to avoidable. At present, our country's many products have great lost because of suffering...
The liveness of Petri net models of parallel programs is a very important property. The existing analysis techniques take Petri net models as a whole to study properties, which is subject to the state explosion problem. In this study, we decompose a parallel program's Petri net model into multiple process subnets to study liveness preservation instead of taking it as a whole, which thus mitigates...
