Carbon-fiber-reinforced polymer (CFRP) composites are widely applied in various important structural components. One of the critical issues in the successful application of CFRPs is the assessment of damage state in a particular structural component. This work describes open electrical impedance tomography (OEIT) as a novel method for damage detection in cross-ply CFRP panels. Different levels of...
In high-rate data orthogonal frequency division multiplex (OFDM) communication systems, many encountered channels trend to have the structure of sparse multipath. The systems over multipath channels usually require that the channel response be known at the receiver and thus channel estimation is required. In this paper, a novel scheme based on the typical least square (LS) and sparse reconstruction...
By using the advantages of modern social tools, a new agricultural information service platform was designed and implemented, which was re developed by WeChat platform. It provided an efficient and convenient information service for farmers, and carried out a wide range of applications in the suburbs of Beijing.
In order to solve the shortcoming of support vector regression, passenger capacity prediction based on least squares support vector regression with ant colony optimization algorithm is proposed in this paper. Ant colony optimization algorithm is used to select the parameters of least squares support vector regression. Highway passenger capacity data of Anhui province from 2000 to 2011 are applied...
Last several years, industrial and information technology field have undergone profound changes, entering "Industry 4.0" era. Industry4.0, as a representative of the future of the Fourth Industrial Revolution, evolved from embedded system to the Cyber Physical System (CPS). Manufacturing will be via the Internet, to achieve Internal and external network integration, toward the intelligent...
The difficulty of speech comprehension under background noise greatly influenced the use of hearing aids. To address this problem, this paper proposes a new hearing aids algorithm based on speech recognition and synthesis. This method is based on the pure speech to build a parameters database. Under the real noisy scene, implement speech recognition for the input speech, and then extract the corresponding...
In wireless sensor networks, the resilient data fusion is an effective method to deal with the malicious attack while it is always energy exhausting, and does not consider the fusion function and the attack detection synthetically, which may affect the accuracy of fusion result. A novel information utility measures based resilient data fusion algorithm is proposed in this paper trying to solve this...
The aircraft target in the airport and its ground background are significant in military applications. In order to employthe algorithms for the detection, identification and dynamic monitoring, a software which can complete infrared radiation simulation of aircraft/ground object in airports under conditions of different seasons, different meteorological conditions, different periods and different...
Growth environment and physiological indices of tropical flower is an important parameter to measure crop growth, while the conventional method has its own limitations. The design combines machine vision and Wifi / 3G technology to achieve a physiological detection system based on Internet of Things through a wireless sensor network environment information collection crop growth, growth of information...
In this paper, we study the existence of non-collision periodic solutions for third-order singular dynamical systems. We consider the systems where the potential have a repulsive singularity at origin and do not need any kind of strong force condition. The proof is based on a nonlinear alternative principle of Leray-Schauder.
Base on the current situation of the development of wireless medical, according to the multi-frequency and broadband MIMO road medical special wireless network system (WIDS) safe use problem, the WIDS themselves security, stability and continuity of network transmission, wireless network impact on human health and the medical equipment is discussed and studied. Based on the research of the system...
Software aging is a kind of objective phenomenon with the decrease of the performance and increase of failure rate of the software system. It is a severe test of the reliability of the software system. However, the time point of software aging is uncertain, and a new method based on non stationary time series modeling is proposed for the problem of the current software aging detection, analysis, and...
By analyzing the generation of fragmentized reading environment in the age of multimedia information and the changes in reading psychology and reading purpose of the cognitive behaviors under such environment, it is discussed in this paper that under the fragmentized reading environment, the reading psychology of users changes from "linearity" to "nonlinearity", and the reading...
With the rapid development of computer technology, it has been widely used in many fields such as politics, economy, military affairs, culture, and education and so on. The society has entered into the information age with the development of computer and network technologies, however, the security problem of information has become the fundamental mater. As we all know, the basic principle of Von Neumann...
This paper presents AFDD, an automatic fault detection daemon for high availability computing. First we compare two mainstream fault detection mechanisms which are commonly used by multiple hot standby systems and figure out their advantages and disadvantages. Next we combined the existing two prevalent technologies together: (1) RASdaemon real-time fault detection tools, (2) automatic bug report...
According to the requirements of practical application, we change the objective function of the TSP problem to the product of the load and distance, and put forward a TSP variation problem. According to the characteristics of the problem and its connection with the TSP, we combine with classic chain 2 - opt algorithm and give the solving algorithm of variant problem. Combined with the instances, we...
Huge pages have been widely supported by architecture and operating system. Huge pages map large fixed virtual memory regions, on the orders of 2MB to 1GB on Intel x86-64 architecture. The page size is the key to striking the balance between trade-off pairs. For example, initially, the use of huge pages aims to mitigate address translation overhead for memory-intensive workloads with large memory...
In this paper the necessity to apply Internet of Things (Hereinafter referred to as IOT) in the coal industry is analyzed. The architecture of a new kind of IOT for coal mine and its main technical indicators are proposed based on sensor technology, combined with Industrial Ethernet, 3G/WIFI wireless networks, wireless sensor networks and other technologies.
Surveys indicate that privacy persists as an issue of public and individual concern. It is a highly relevant issue in systems engineering today, and the need for privacy studies will be escalating substantially in the coming years as agencies increasingly turn to Internet-based cloud computing, however, conceptual difficulty exists in defining privacy. According to researchers in the field, prominent...
Quality of holographic images reconstructed from digital holographic information system with monochromatic CCD is higher than that from the colorful CCD. We want to use one singular monochromatic CCD to work in the information system of colorful phase-shifting digital holography. After the formulae are deducted and computer programs are designed, we extracted phase shifts, reconstructed the corresponding...
