The modification of sodium trititanate whisker surface was performed by means of impregnation procedure to fabricate the modified sodium trititanate whisker, which was characterized by scanning electron microscopy(SEM) and infrared spectroscopy(IR). Its adsorptive performance for Co(II), Pb(II) in a static system was investigated by inductively coupled plasma atomic emission spectrometry(ICP-AES)...
RFID (Radio Frequency Identification) and WSN (Wireless Sensor Network) are technologies that be widely used and have a profound impact on human society. This paper puts forward a WSID identification platform of heterogeneous network which integrates wireless sensor networks technology, RFID technology, GIS location technology together. The platform uses dual-frequency-and-dual-protocol RFID readers...
For the radiotherapy, the tumor inside thorax or abdomen keeps varying with respiration motion. Current technologies, e.g., respiratory gating and beam tracking, face great challenges in predicting the respiratory tumor motion. Whereas respiratory motion is changeful, traditional prediction model such as Linear Model, Kalman Filter, and so on, can not imitate the motion accurately. In this article,...
This paper introduces a design solution of UHF reader based on AS3991 and the selection for key parts is finished. The paper expatiates the hardware structure, working flow and software design. The UHF reader operates at the frequency of 912MH, it can support the mainstream standards of 900MHz RFID EPC Gen2 and ISO18000–6C/6B. Using the internal PA and internal VCO which integrated on the RF chip,...
Based on the engineering construction of new subway across existing metro tunnel, the settlement law of the existing metro concrete structures was researched due to construction perturbation under existing metro tunnel. According to the in-situ monitoring information and engineering geological conditions, the foundation model, structure analysis model and settlement curve model which are suitable...
The construction of highway tunnel entrance is always difficult, the good and bad entrance ways of tunnel directly influence the construction schedule and exterior environment quality. Based on Keshutu tunnel entrance engineering, the half-open and half-hidden entrance way of half hollow-out form was simulated by considering topography, geology and environmental conditions in the paper. The results...
In this article, we first fabricate and demonstrate the InGaP/GaAs camel-like gate field-effect transistor with InGaAs pseudomorphic heavy-doped channel. Due to the large gate potential barrier for the use of the n+-GaAs/p+-InGaP/n-GaAs camel-like gate and the thin as well as heavy doping n+-InGaAs channel layer, the effective conduction band discontinuity (ΔEc) is substantially extended and a high...
In this article, the performance of a novel InGaP/GaAs superlattice-emitter bipolar transistor with InGaAs/GaAs superlattice-base structure is demonstrated by experimental results. The injecting electrons from superlattice emitter are easy to transport into the superlattice-base region for promoting the collector current by tunneling behavior. Furthermore, the average energy gap of base regime is...
As an effective tool for knowledge discovery, concept lattice has been successfully applied to various fields. One of the key problems of knowledge discovery is knowledge reduction. The existing work on attribute reduction has not focused on aquatic lives disease diagnosis (ALDD). This paper describes an improved incremental approach of attribute reduction in concept lattice for ALDD. Firstly, the...
Key techniques on virtual endoscopy are researched in this paper. We use boundary model and local feature structure to realize tissue segmentation. A new efficient algorithm is presented to solve path planning based on distance transform. As for real-time processing, a frame in virtual endoscopy is divided into near viewpoint part and far viewpoint part based on volume data characteristics in our...
With the development of wind power on a large scale, more and more wind sources will be integrated into power grid. However, due to intermittent nature, power grid dispatch will face new difficulties. It is necessary for us to analyze wind power systems and locate the specific points of power loss. This is of great significance to timely adjust the output of the remaining units to keep the balance...
The life-long education system is the inevitable outcome of social development. Non-diploma education came into being as a new form of education with the development of society, which has become the essential form of education to remedy the shortage of academic education resources under informationization environment in our country. The paper illustrates the role of non-diploma education in constructing...
This paper describes a novel method based on self-adaptive subdivision mesh for geometry correction of multi-cameras in a panoramic video system. The system hardware consists of an array of six board cameras pointing outwardly. Digitally combining synchronized frames from each camera, a wide-field panoramic video can be created. Using sparse initial corresponding points between the ideal target surface...
With the vast increase in collection and storage of data, the problem of data summarization is most critical for effective data management. Since much of this data is categorical in nature, it can be viewed in terms of a Boolean matrix. Boolean matrix decomposition (BMD) has been used to provide concise and interpretable representations of Boolean data sets. A Boolean matrix can be expressed as a...
Development of the Spatial Information System(SIS) consists of the Remote Sensing and the Geographical Information System and Global Navigation Satellite System, that etc provides the vast road into the fast and accurate inquisition of the resources, also provides the brand-new means to the obtain quickly and management and applications of the medium relevant information in sustainable development...
The application of motivation psychology on crowd simulation is an interesting topic. Agents in a crowd should have motivations and behaviours, and make decisions in a certain virtual environment by themselves. A formalization of motivation is presented by fuzzy mathematical methods and a computational motivation model for agents is set up. An agent's local motion within a group is based on Helbing's...
A model of fish disease diagnosis was proposed by combining rough sets theory (RST) with classifier fusion. On the basis of the attribute reduction of RST, the remaining condition attributes were used for the inputs of individual classifiers and the decision attributes as the outputs. The application of ordered weighted averaging (OWA) operator as a classifier fusion approach has been adopted to combine...
In this study, the optimal conditions of production of bioflocculant by the culture of Pseudomonas alcaligenes PS-25 were examined, using brewery wastewater to replace glucose as carbon source and energy source in the culture medium. Results showed that the COD concentration in brewery wastewater favorable for the production of the bioflocculant was 5000 mg??L-1, and an optimal culture condition of...
The tapered narrow side waveguide is applied into the waveguide-to-coaxial transition to obtain a wider band. The simulated results testify that this structure is useful to make good impedance matching.
As a complex ecosystem of society, economy, resources and environment, small towns’ development with multiple complicated factors involved, Urbanization and sustainable development are very important. In this paper, a coordination model was given to analyze the relationship of urbanization and sustainable development and verified through the demonstration on Hengdian town, a town of national sustainable...
