摘要:
The existing transportation service system in public travel route can not satisfy the people's actual travel need because of various technologies reasons. In our study, we set the tourist attractions as a vertex, and simplified the traditional algorithm for complex network computing. Aim to improve the disadvantage of tradition Dijkstra algorithm, an improve algorithm was proposed to improve the path search efficiency. Then the improved Dijkstra algorithm was applied to tourism path search. The experimental results have illustrated that the improved Dijkstra algorithm can accomplish a better result and improve path search efficiency.

摘要:
Human face three-dimensional (3D) reconstruction is a challenging problem. In this paper, we propose a human face fast- 3D- reconstruction method based on image processing with a single image. Shape from shading (SFS) is chosen to reconstruct the human face. First, SFS theory is introduced. It has the advantage of fast 3D reconstruction and only need a single image. Secondly, because the noise will affect the 3D reconstruction result greatly, wavelet transform and wavelet packet transform are introduced and used in image denoising respectively. The experiment has shown that the method based on wavelet transform produces the best denoising result than wavelet packet transform. At last, a human face 3D reconstruction algorithm based on a single image is proposed. The experimental results show that a human face 3D model can be reconstructed in fast by proposed algorithm.
摘要:
With the difficulty of student employment is increasing, the correct occupation choice view has a crucial influence on their career. To know the occupation choice view of PE students and put forward the corresponding countermeasures according to the problems are very crucial in PE students' employment after graduation. By using the methods of literature, questionnaire survey and logic analysis, this paper analyzes the career views of college students in Physical Education Majors. The results showed that: sports education college students can appraise the current situation correctly, but being unclear and unable to know themselves correctly. The places they prefer to work tend to capital city and provincial-level city, and they are unwilling to go to the western regions. The main way to apply for a job of them is to take part in all kinds of examination and recruitment. They lack of a pioneering spirit and tend to pursuit stability. Their values are more and more utilitarian; the first factor they consider is choosing jobs with high welfare and benefits, the second is the personal prospect, which indicates their lack of scientific and clear career planning.

摘要:
Research on SMT solder joint image segmentation can formed feedback information of the products assembly which is used to control and adjust the SMT assembly, and is useful to guide SMT to improve the quality and process of SMT products. In our study, we improve a novel approach of SMT solder joint image segmentation. During our method, the process has three steps. At first, the RGB image of solder joint is converted into HSV image. Second, we segment the solder joint by color domain 2D histogram threshold. Last, mathematics morphology processing is used to improve the segment accuracy. Experimental results show that the proposed method retains the structure of the solder joint images leading to an effective segmentation.

摘要:
The principles of the Surface Mount Technology (SMT) product character segmentation and its technology could be described as following: SMT product character image is obtained by image sampling equipment and its ideal binary images is got after image processing. In order to segment the SMT product character effectively, a novel character segmentation algorithm is proposed based on contour feature. Three kinds of information are extracted, one is the up contour feature, another is the under contour feature, the third is the width and the height of the image. Then the position of character segmentation is determined according to the width and height of single character, and character segmentation can be accomplish according to its up contour feature and under contour feature. By analyzing the test result, the proposed approach has excellent properties in character segmentation.
摘要:
Although widely applied in many industries, anionic surfactants (AS) have been shown to contaminate the natural environment. Therefore, the detection of trace amounts of AS in environmental samples is of great interest. Here, we report a novel fluorescence quenching method for the determination of trace AS, specifically, sodium dodecyl sulfate (SDS), using 1-(5-naphthol-7-sulfonic acid) -3-(4-pheny-lazophenyl)-triazene (NASAPAPT). Under optimum conditions, the degree of fluorescence quenching is linearly proportional to the concentration of SDS from 2.08×10-8 to 8.67×10-7mol L-1 with a detection limit of 8.35×10-9mol L-1. The proposed method exhibits high sensitivity and selectivity, yet it avoids the use of toxic organic solvents and tedious solvent extraction procedures. It has been applied to the determination of trace SDS in both natural water and industrial samples with recoveries between 99.04 and 103.58%. Results indicated that the hydrogen bonds formed between NASAPAPT and SDS played an important role in the detection process and that the π→π* transition was crucial for fluorescence of the NASAPAPT complex.
摘要:
In the paper, Authors separately used analytical hierarchy process, expert scoring method, principal component and BP network to establish the weights of ecological vulnerability evaluation Index system in the Hengyang Basin as a case, and used hierarchical-comprehensive index -clustering model, principal component-comprehensive index-clustering analysis model, expert scoring-composite index-clustering analysis model, BP artificial neural network model to evaluate separately the reality vulnerability in 2000. The results shows that study area are moderate weak, and the results broadly similar. Authors think that Principal component and artificial neural network model can avoid subjective factors, and taking the way of the expert group judgment is to reduce the error of ecological vulnerability assessment. With the impact of global change and the strengthening of fragile ecosystems, China has carried out many researches and practices on vulnerability assessments[1,14]. Although Vulnerability assessment in many ways, not yet formed a unified evaluation method, this paper draw on previous evaluation methods based on [1,11], using AHP, principal component analysis, BP neural network and expert scoring method on quantitative assessment and analysis, then clustering the results by comparison to determine which method to evaluate the most accurate. Authors analysis the Hengyang Basin reality vulnerability in 2000, attempting to explore a more suitable and easy erosion in hilly areas degraded fragile vulnerability assessment method.

摘要:
Six new 3d-4f heterometallic coordination polymers, {[Ln4Cu2(INAIP)8(H2O)15]·14H2O}n [Ln = La (1), Pr (2), Nd (3)] and {[LnCo0.5(INAIP)2(H2O)2]·2H2O}n [Ln = Tb (4), Dy (5), Yb (6), H2INAIP = 5-(isonicotinamido)isophthalic acid] have been synthesised and characterised by single crystal X-ray diffraction analysis. The results of structural analyses showed that 1–3 are isomorphous showing two-fold interpenetrated three-dimensional (3D) coordination framework, while 4–6 have the same non-interpenetrated 3D structure with 2D (4, 4) lanthanide-carboxylate layers. The results revealed that the different transition metal centres have great influence on the structures of the resulted complexes in this system. In addition, thermogravimetric and magnetic properties of 1–6, and photoluminescence of 4 were investigated.

Association rules;Fup;Updating algorithm
摘要:
To solve the incremental updating of association rule, this paper proposes an effective and simple updating algorithm based on list. This paper analyses this algorithm and compares with the Apriori algorithm and the FUP algorithm. This algorithm makes full use of the previous mining information and the efficiency of the insert and delete of the list. The algorithm scans the original and the updated database only once and achieves new association rules. This paper proved that the mining time and the result integrity of this algorithm are better than the traditional association rules by experiment.
摘要:
Batch experiments were conducted under static and dynamic conditions respectively to explore the mechanism and kinetics of U(VI) immobilization by zerovalent iron (ZVI) and the impact of pyrite. The dynamic results suggest that the U(VI) immobilization reaction by ZVI shows pseudo-first order with respect to U(VI) concentration. When the initial U(VI) concentration increased from 50 to 300mg/L at a fixed ZVI loading (2%), the rate constantly decreased from 0.1776 h(-1) to 0.0177 h(-1). The static results show that ZVI system removed U(VI) very quickly whereas the FeS(2) system did the most slowly. As for the ZVI+ FeS(2) system, the U(VI) immobilization process was significantly inhibited in the presence of pyrite. The fixation of U(VI) may chiefly rely on the chemical reduction under dynamic conditions, but on the coprecipitation with iron corrosion products under static conditions. The latter process was also associated with pyrite lowering the system pH and controlling the amount of iron oxide.
