A multiaxial pre-stretched PAC technique is used which endows 200 % stretch-ability to flexible and transparent electrodes based on graphene and Ag-NWs hybrid structures. A novel bubble template method is used for uniform distribution of Ag-NWs which decrease the resistivity of electrodes remarkably and enhance the connectivity between graphene segments when graphene gets partially divided into small...
To improve the retrieval rate of contourlet texture image retrieval system, a contourlet-2.3 transform based texture image retrieval system was proposed. In the system, the contourlet transform was contourlet-2.3, a new version of the original contourlet, sub-bands absolute mean energy and kurtosis in each contourlet-2.3 sub-band were cascaded to form feature vectors, and the similarity metric was...
This paper presents the research and design of an active bistatic vector positioning system. The designed positioning system uses a low frequency active sound source. The vertical vector sensor array is used as the signal receiver, which consists of four elements. The vector hydrophone's natural combined directivity can be applied to suppress the strong direct path interference and the following reverberation,...
Site infrastructure sharing is the trend of future base station construction. Telecom infrastructure operators require for smooth upgrading and low TCO when sharing sites power supply, spaces and operation management. This paper introduces a new integrated hybrid power supply system suitable for the site sharing requirements. It perfectly combines many functions together, such as energy generation,...
With the rapid growth of dataset, more and more traditional applications turn into big data applications running on cloud platforms. This trend has continued, and even accelerated. Compared with traditional applications, big data applications spend lots of time to transfer data among computing nodes. Hence, the communication optimization is a must for big data applications. Network topology and routing...
Network topology and routing are two important factors in determining the communication costs of big data applications at large scale. As for a given Cluster, Cloud, or Grid system, the network topology is fixed and static or dynamic routing protocols are preinstalled to direct the network traffic. Users cannot change them once the system is deployed. Hence, it is hard for application developers to...
Template-based composition of web services allows users to define templates with specified activities and to construct the control flow among the activities. And appropriate web services can be discovered and selected for each activity. However, choosing compatible services requires precise formal specifications of activities and templates because supporting systems lack "memory" of previous...
The contribution of this paper is a conceptual architecture based on intelligent services for manufacturing support systems. Current approaches cannot cope with the dynamism inherent in the manufacturing domain, where unexpected and drastic changes occur at any time and affect cross-boundary systems. Our approach alleviates these issues and focuses on the need for supporting real-time automatic negotiation,...
In this paper we introduce a content-based recommendation approach for assisting buyers of high involvement products with their purchasing choice. The approach incorporates a group-based, fuzzy multi-criteria method and provides personalized recommendation to end-users of e-Furniture. E-Furniture is an agent-based system that offers decision making and process networking solutions to furniture manufacturing...
In this paper, we aim to track objects that undergo abrupt appearance changes and heavy occlusions. To address these problems, we propose an online structure learning algorithm which contains two layers, block-based online random forest classifiers (BORFs) and online structure models (OSMs). BORFs are able to handle occlusion problems since they model local appearances of the target. To further improve...
Epoxy/organic-montmorillonite nanocomposites were prepared with different organic-montmorillonite and content of montmorillonite by diglycidyl ether of bisphenol A. Chemical composition of different organic-montmorillonite was analyzed by Fourier Transition Infrared(FTIR). The temperature properties of resistivity of composites were measured by Megger. The temperature dependence of composites dielectric...
Glyphosate is an efficient, low toxicity, non-selective post-emergence herbicide. In this work, Glyphosate molecular structure was optimized by Hartree-Fock(HF) approximation method. Glyphosate molecular Raman and infrared spectra was calculated based on HF/6–31G sets and DFT/6–31G sets, then two theoretical Raman spectra were carefully compared with others experimental spectra, good agreements were...
The importance of corporate social responsibility (CSR) has aroused wide attention of not only the corporation itself, but also the whole society. In 2006, SGCC (State Grid Corporation of China) published its first CSR report, started to make a commitment to social responsibilities. Since then, the five power generation groups published their CSR reports, sustainable development reports, or development...
Vehicle detection in traffic scenes is a fundamental task for intelligent transportation system and has many practical applications as diverse as traffic monitoring, intelligent scheduling and autonomous navigation. In recent years, the number of detection approaches in monocular images has grown rapidly. However, most of them focus on detecting other objects (such as face, pedestrian, cat, dog, etc...
Hand posture recognition (HPR) plays an important role in human-computer interaction (HCI) since it is one of the most common and natural ways of communication among human beings. Different fingers often represent different meanings which will attract more attentions in HPR research. Based on finger geometric feature and its classification, we develop a HPR system that can tell its posture on possible...
This paper focuses on tracking multiple vehicles in real-world traffic videos which is very challenging due to frequent interactions and occlusions between different vehicles. To address these problems, we fall back on superpixel which recently has received great attention in a wide range of vision problems, e.g. object segmentation, tracking and recognition, for its ability of capturing local appearance...
Multi-view vehicle detection and tracking in crossroads is of fundamental importance in traffic surveillance yet still remains a very challenging task. The view changes of different vehicles and their occlusions in crossroads are two main difficulties that often fail many existing methods. To handle these difficulties, we propose a new method for multi-view vehicle detection and tracking that innovates...
PLC (programmable logic controller) is one type of general industrial control platforms with high reliability. Based on the PLC of SIMENS SIMATIC S7-200 series, this paper introduces a control scheme of the manipulator transportation control system. The hardware design and PLC programs are given in details. In addition, the configuration simulation of the control system is performed by the application...
Crowd counting which aims at obtaining the number of people within a scene is an important computer vision task. While most previous methods try to count people within one frame, this paper addresses this problem using the detection flow which is defined as a set of object detection responses along the temporal video sequence. We argue that counting based on detection flow provides a better way to...
Background subtraction plays a key role in many surveillance systems. A good background subtractor should not only be able to robustly detect targets under different situations (e.g. moving and static), but also to adaptively maintain the background model against various influences (e.g. dynamic scenes and noises). This paper proposes a novel background modeling approach with these good characteristics...
