During the NIR spectral analysis to quickly determine concentrations of essential components of milk, spectral region is wider, peaks are overlap, and searching space is larger, spectrum acquiring often subjects to interference coming from environmental noise and interference of other components, so it is necessary to make optimum selecting to wavelength variables. In this paper, for concentration...
Wind power is widely used to replace conventional power plant and reduce carbon emission. However, the variability and intermittency of wind makes the wind power output uncertain, which will bring great challenges to the electricity dispatch and the system reliability. So it is very important to predict the wind power generation. Two different signal decomposition methods are introduced into the prediction...
Mould fungi do not only occur on the inside surface of external building components, but even inside construction parts. Indoor mildew pollution in building makes indoor air quality bad, threatens human's health, shortens the building' s life and affects its appearance severely. According to the lifecycle and growth conditions of mould such as moisture conditions, temperature conditions, nutriments...
Building energy consumption in China has been increasing rapidly. And a small increase in the operation efficiency of the air-conditioning system can substantially decrease it. In this paper a new type heat pump is developed to improve the performance of conventional air-source heat pumps. The major components of heat-source tower heat pump units are closed-type heat-source tower (cold and heat sources...
The purpose of this study is to evaluate the quantification of carbon footprint over the full life cycle of a large public building by establishing the framework of carbon footprint evaluation system. The theoretical basis of the framework is the life cycle theory, the gray system theory and the analytic hierarchy process. A quantity of real data should be collected by questionnaire, site survey scene...
We investigate the outage probability for amplify-and-forward (AF) and decode-and-forward (DF) relaying in OFDM-based cooperative networks. To minimize the outage probability, the relay which has the maximum received SNR is selected as the cooperative relay. Based on the relay selection, the problems of optimal power allocation and placing relays in the optimal position are discussed. And the expressions...
For improving systematization degree and efficiency of security diagnosing for construction producing, the flow of security diagnosing for construction producing system by CBR is designed. By analyzing the security influence factors for construction production systemically, the case presentation technology for security diagnosing for construction producing is designed, and the case retrieval, case...
When large scale emergency incident happens, the multi-category emergency goods distribution is a complex problem. To improve structure and efficiency of emergency goods distribution, a multi-objective non-linear optimization programming model for emergency goods distribution is established. Modeling precondition is analyzed in detail, some objectives such as minimizing the waiting time, the transportation...
With the purpose to enhance efficiency and accurate of emergency dispatch, realize reasonable distribution material quantity, reduce life and property loss caused by paroxysmal emergency events, a dynamic continuous consumption emergency scheduling model is established. Some features of emergency scheduling goals are analyzed. The objective function includes minimizing earliest emergency start time...
To improve practical efficiency and theory feasibility of house repair or reinforce measures so as to reduce life and property loss as could as possible after large scale earthquake, the two stage CBR implement mode is proposed to realize expert system for house repair or reinforce after earthquake. The first stage CBR system is employed to make out house repair strategies, and the second stage CBR...
SNR estimation of LFM signal detection is often applied in radar, mobile communications, Radiolocation and seismic exploration with vibrator. The common method of LFM signal detection is correlation, which can not only be used to explain time delay in Multipath Propagation, but also to estimate SNR in detection of output signal. The records of signal plus noise before the signal detection are called...
On the theory of GIS and Evaluation and management of groundwater, a network of hydro-geological information systems has been developed. Model base management subsystem is designed, in which parameter calculation model, mining prediction model, and groundwater resources management model are included. Groundwater resource management model is build and applied in practice in this paper. Groundwater...
In designing new wells, hydrogeologic operators often make a rough estimation through drawing lines method, according to stratum, aquifer and electric measuring curve of reference wells. This method can not meet the requirement of imprecise for its insufficiency of utilizing data of reference wells. How to analyze the distribution of stratums and aquifers of new well has become a serious problem to...
In order to get more accurate movement information of moving objects, and to capture the temporal trajectory of the spatial uncertainty, this article describes the uncertain trajectory model of the moving objects in the road networks databases, and extends the structure of the MON-tree index based on the road network. The uncertain geometry between two sampling points is divided into pieces, which...
The development of wind generation has rapidly progressed over the last decade, but it must be integrated into power grids and electric utility systems. However, it cannot be dispatched like conventional generators because the power generated by the wind changes rapidly because of the continuous fluctuation of wind speed and direction. So it is very important to predict the wind power generation....
