Journal of Jilin University Science Edition. 2014, 52 (01):  39-44. 
Abstract ( 233 )   PDF (1160KB) ( 294 )  

An ultra weak variational method was proposed for the time harmonic scattering problem in view of total internal reflection microscopy as a model. Based on the partition of the computational domain, the problem was transformed into the one on the skeleton of the mesh. By Green identity, the equivalent ultra weak variational formulation was deduced. Then plane wave functions and evanescent wave functions were used to approximate the local property of the solution. The method is suitable for the problems with big wave number, and has a fast rate of convergence, by which  the scattering problem in near field can be effectively solved.

CHEN Yongheng, ZUO Xianglin
Journal of Jilin University Science Edition. 2014, 52 (01):  59-64. 
Abstract ( 149 )   PDF (537KB) ( 334 )  

Multijoin query optimization is one of the key problems in database searching. As multicores replace traditional single processor because of the advantages of their high performance and low energy consumption, researches on bottomup dynamic query parallel algorithms have become popular. However,  the advantages of topdown dynamic query algorithm  can not be replaced by bottomup dynamic query algorithms, such as cut algorithm. Based on bottomup and topdown algorithms, this paper proposes a graph traversal twoway optimization algorithm  on the multicores system. The proposed approach makes full use of the  advantages of both topdown and bottomup algorithms, gives full play to multicores environments, realizes high performance parallel construction of optimal query plans, thus resolves parallel twoway enumeration join problem. Experimental result shows that the proposed algorithm outperforms existing algorithms, and can effectively increase the speed of database query.

LI Aichen, LI Xiangshan, JIAO Jianyu, ZHANG You
Journal of Jilin University Science Edition. 2014, 52 (01):  65-70. 
Abstract ( 202 )   PDF (419KB) ( 264 )  

The problem of reliable control of discretetime nonlinear systems with actuators faults was studied via developing a reliable controller based on the Takagi-Sugeno fuzzy model. As those existing reliable controllers are based on the parallel distributed compensation, the one given in this paper is with special control structures named as nonparallel distributed compensation. Therefore, more control gain matrices are introduced and the conservatis
m of existing results is reduced. Moreover, a method for introducing free matrix variables was also proposed in the proof of our main result, and hence the conservatism of the obtained results could be further reduced. Finally, the effectiveness of the proposed method is illustrated by means of a numerical experiment.

HU Yating, ZUO Chuncheng, QU Fuheng
Journal of Jilin University Science Edition. 2014, 52 (01):  86-92. 
Abstract ( 180 )   PDF (1393KB) ( 265 )  

To deal with the parameter sensitivity problem of possibilistic c-means clustering algorithm, a new possibilistic clustering algorithm based on center merging was proposed. The cluster number and structure were dynamically adjusted according to the data distribution. The algorithm has the ability to execute multi\|scale analysis task for the given data set by means of adjusting the values of the scale factor. The theorems were also given that were proven to be used to analyze the multiscale property of the algorithm. Compared with the traditional fuzzy or possibilistic clustering algorithms, the proposed algorithm avoids its dependence on the initial conditions of centers, cluster number and membership matrix, which makes it easy to control. Synthetic and real data experimental results show that the algorithm can be used to detect the cluster structures of the data set from different scales, and to find the clusters with different sizes.

Journal of Jilin University Science Edition. 2014, 52 (01):  126-130. 
Abstract ( 296 )   PDF (2581KB) ( 210 )  

The microstructures of  organic nanowires with a high mobility, a kind of PPV oligomer substituted by bisurea with alkyl chain (OUPV), were investigated computationally on the basis of monomer, dimer and trimer via DFT/B3LYP method. Then the absorption spectra of the single molecule and the aggregate state were calculated at the level of ZINDO and TDDFT. The results indicate that the intermolecular array of OUPV was attribuled to hydrogen bond interlocked “facetoface” π-π-stacking,  forming  the channels for highlyefficient carriers transfer. Owing to the strong hydrogen bonding interaction, the onedimensional organic nanowires preferentially grew along this direction. The calculated results agree well with the experimental data and phenomena. 

Journal of Jilin University Science Edition. 2014, 52 (01):  137-143. 
Abstract ( 216 )  

The mass concentrations and species of nitrogen and phosphorus in the sediments of Liaohe River and its main tributaries in Jilin Province were analyzed by chemical extraction. The release processes of ammonia nitrogen and dissolved phosphate from the sediments were simulated under laboratory conditions. The results showed that the TN and TP mass contents were higher in the [JP2]sediments of the Yangmu Reservoir and the Tiaozihe River, a Liaohe River tributary (1.09—3.00 g/kg).[JP] The TN and TP mass contents were lower in other sediments of Liaohe River and its tributaries (0.25—0.70 g/kg). The ammonia nitrogen mass content was relatively high in the sediments of the middle and lower reaches of the Yangmu Reservoir (0.044—0.052 g/kg). Caboundp P, organic phosphorus and residual phosphorus were the main forms of TP. The mass concentrations of exchangeable P, Albound P and Febound P were low. Acidic condition promoted the release of ammonia nitrogen and phosphate from the sediments. Alkaline condition  favored
 the release of ammonia nitrogen from the sediments. The release processes were influenced by microbial activities, pH and dissolved oxygen content.

WANG Hongliang, ZHONG Yubo, SHI Lei, KANG Chunli,LIU Hanfei, CHEN Baiyan, LIU Tingting, WU Jiayu
Journal of Jilin University Science Edition. 2014, 52 (01):  144-150. 
Abstract ( 140 )   PDF (780KB) ( 285 )  

The photolysis of phenol in a UV/H2O2 system in ice was investigated and the effects of pH value, light intensity and the initial concentration of H2O2 on the photolysis of phenol were discussed. In addition, Hydroxyl radicals (·OH) generated during the photolysis of phenol were trapped by dimethylsulfoxide (DMSO), thus the effect of·OH radicals on the photolysis of phenol was studied. The results show that H2O2 significantly increased ·OH generation and enhanced the photolysis of phenol in ice. Changing light intensity, pH value and the initial concentration of H2O2, the photolysis rate of phenol would increased with the increase of·OH generation. The addition of NO-2 and NO-3 inhibited the generation of·OH and the photolysis of phenol. But SO2-4 had no impact on·OH generation and the photolysis of phenol. Though CO2-3 and HCO-3 decreased ·OH generation, they also had no impact on the photolysis, which might be due to the other radicals generated in the system.

Abstract ( 189 )   PDF (954KB) ( 239 )  

The mass contents of 16 polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the second Songhua River were investigated. The total PAHs mass rate varied from 350.0 to 3 877.4 ng/g, with the mean value being 1 322.6 ng/g. The 4—6 rings PAHs made up 58.5%, whereas 2—3 rings PAHs made up 41.5%. The study shows that the mass content of PAHs was the highest in the surface sediments of the upstream of the second Songhua River. The total mass content of PAHs was close to that of the Yangtze River estuary. In addition to that from the source regions, the PAHs in the sedimen
ts were mainly from anthropogenic emission. Anthropogenically produced PAHs in the sediments in most of waters was from the burning of fossil fuels and a small part was from the petroleum derived. Exposure risk assessment results show that in addition to the fluorene and acenaphthylene, there was not obvious risk of exposure of other polycyclic aromatic hydrocarbons. The total mass content of PAHs in the sediments of the second Songhua River was much lower than the effects range\|low (ERL), and there was not obvious risk of exposure basically.
