Space form the various elements is reflected in the construction and combination of continuous derivative, rooted in the residential building and self-improvement is the development...
Smart Grid is gradually prevalent to human's daily life. More customers hope their home grids smarter to realize energy saving, intelligent controlling and real-time monitoring. The advent of Home Area Network (HAN) supported by multiple IEEE network technologies makes the thinking true together with difficulties and challenges on the field designs and assignments. Simulation is important for analysis...
This study is carried out from a three -day field measurement in studies of the potential effects of urban river on urban thermal climate and thermal comfort, using fixed point observation method in the summer of Harbin and the sites are located in the section of Songhua River Basin. Fixed point measurement on the research of river impact on the urban climate is developed based on the theory of water...
Progresses in the study of speciation and biological uptake of arsenic in soil are introduced. The researches on bioavailability of arsenic are summarized, and the main factors which affect arsenic bioavailability are emphatically discussed. Relationship between speciation and availability of arsenic is concluded and the concerned problems and future development orientation are pointed out.
This paper presents a rate-distortion based optimal quantization scheme for DC coefficient in the unidirectional Wyner-Ziv (WZ) video coding system. In the proposed scheme, a new rate-distortion (RD) model is developed to find out an optimal quantization step (OQS) for DC coefficient. More specifically, the effects of quantization step on both distortion and rate are considered in our presented RD...

According to the general service design process, develops a process for service based on product life cycle. Finally, this paper proposed service model based on product life cycle.
According to average value and characteristic points and lines of typical curve for dual media, the proper value analysis method was applied here, deviating mathematical expressions of exact resolution for the dual-porosity characteristic parameters such as interporosity flow coefficient (λ) and storage ratio (ω) in non-shut-in well test analysis of high pressure gas well , And taking examples to...
The informationization is an important support to promote the balanced development Chinese compulsory education, however, it was restricted seriously by existing problem of lacking infrastructure, teachers deficiency, lacking information technology personnel and so on. Therefore, through analyzing the informationization of Chinese rural education, this article proposed that the development and application...
This paper bring forward one new method of target automatic orientation and we establish the target positioning system basing on dual antenna GPS receiver. We analysis the principle of target orientation and make an emulation of the system. The results show us that the method has high precision. Then, we make many times experiments. The results of experiments show us this system has high precision...
Many spatial decision making problem not only includes spatial analysis and display, but also includes conflicting solutions, how to find multi-objective solutions is important for spatial decision making. This paper developed a spatial data mining module based on multi-objective optimization to solve multi-objective spatial data mining problem. The application case improve that the spatial mining...
For the gas well with high H2S content,the process of sulfur deposition including the sulfur dissolution, precipitation, migration and deposition is a quite complex process. Relative to the solubility of sulfur under certain temperature and the pressure, the sulfur will be separated out when the content of sulfur in high sour gas is surpassed. Based on the theories of mass conservation, momentum conservation,...
Designing a general model of human resources management information systems fitted on corporate strategy based on related research from domestic and foreign scholars. Additionally, Sanjiu Medicine Co., Ltd. has been adopted for case study, systematically elaborated processes and patterns of human resource management information systems fitted on corporate strategy. The results show that the establishment...
Industrial cluster, like the organism, has its own process of evolution. Clusters from birth to the growth stage, have completed the initial accumulation of capital, and began the evolution to the mature stage. How to successfully evolve becomes the research focus in the majority of scholars. In this paper, we study the dynamic factors of the growth stage of industrial clusters in HeBei Provice, JingXian...
In order to improve the optimizing efficiency, one-dimensional blind-walking optimization method is proposed, which can be realized by halving step or doubling step for the applicability test condition of the sensing point. The optimum point, then, can be reached at high rate by doubling step and converged by halving step. Current point should be updated in whole design space. The flow chart of this...

The features of startup process and the reasons which result in the failure of small-scale flat-plate type capillary pumped loop (CPL) evaporator during the preheating stage are analyzed. The unsteady heat transfer model of evaporator in the fully-flooded startup stage is presented, and the model is solved with SIMPLE algorithm. The numerical results show the preheating stage of evaporator requires...
According to the characters of the logistics center location project evaluation, considering that the incomplete and uncertain intraval attribute information of the logistics center location evaluation can be reflected effectively by the traditional extension decision-making model, Extension decision-making model with grey interval number is proposed based on the grey system theory. At the course...
An accessorial loop with a micro-pump and ejector is applied into the Capillary Pumped Loop (CPL), and a 3-D model is developed to investigate the operation performance of the ejector. The numerical results show that the mass flux can be enhanced with an accessorial loop. However, a sub-cooler is necessary to locate between the outlet of the ejector and the inlet of the evaporator to condense the...
