Abstract ( 49 )   Save
As for a decision system with both missing attribute values and mixed data types,the classical rough sets theory cannot directly do anything about it.Such a decision system was firstly defined as the incomplete mixed decision system (IMDS).Secondly,the limited neighborhood relation was proposed for composing the attribute reduction algorithm of a novel incomplete mixed decision system for IMDS,which employed the conditional entropy as the heuristic factor to make up for the positive region of decision deficiency.Based on the limited neighborhood relation,the nominal attribute and the numerical attribute and the missing attribute could be handled simultaneously by the proposed reduction algorithm without the discretization of numerical attributes or completing the incomplete data.Finally,the proposed reduction algorithm was tested on several UCI data sets.The experiment results show that the reduction algorithm can select the core attributes on the condition of keeping or improving classification accuracy.Also,how to impact the classification when specifying the value of the threshold used in the limited neighborhood relation is specified also discussed.

Abstract ( 75 )   Save
Histogram equalization (HE) makes the average of equalized image close to gray median regardless the original image.The gray levels of HE are degenerated and the detail of the image is lost,and the over enhancement and unnatural effect is occurred easily.For bi-histogram equalization,original image is decomposed into two sub-images based on an appropriate threshold and the sub-images are equalized independently.However,the threshold is the key issue.The iterative method for choosing the threshold of the bi-histogram is proposed previously,i.e.iterative threshold based brightness preserving bi-histogram equalization (IBBHE).Experimental results on dim medical image show that this method not only keeps the image brightness,but avoids the phenomenon of over enhancement.Based on partially overlapped sub-block histogram equalization algorithm (POSHE),an iterative threshold based partially overlapped sub-blocks bi-histogram equalization algorithm is proposed (IPOSBHE) and the iterative method is adopted in the process of sub-block histogram equalization.Experimental results on both dim medical image and bright scene image show that the local image details are enhanced,and the input image brightness is also preserved effectively.The blocking effect on the image is eliminated and the equalized image shows a more natural visual impression.

Abstract ( 52 )   Save
In the wireless sensor network with a mobile sink,the mobile sink and the sensors use their shared keys to communicate with each other securely.When some nodes are captured by the adversary,the key information maybe exposed.If each node stores large number of keys,it would reduce the network resilience.Otherwise,it may reduce the network connectivity.In order to solve this problem,this paper proposes a new key pre-distribution scheme,named N-PGPS,which is based on the algorithm of PGPS.This scheme adopts a symmetric polynomial φ(x',y') to produce a perturbed key,which enhances the network resilience effectively.In addition,changing the value of t and s in N-PGPS can also increases the network connectivity observably.The analytical results clearly show that the new schemes perform better in the aspect of network resilience and network connectivity than the existing key pre-distribution schemes in a wireless sensor network with a mobile sink.

Hemin aptamer was used to modify gold nanoparticles (AuNPs) to obtain a stable aptamer-nanogold probe (AussDNA).In the condition of pH8.0 Tris-HCl buffer solution containing 50 mmol/L NaCl,the substrate chain of AussDNA was cracked by hemin to produce a short single-stranded DNA (ssDNA) and then further combine with hemin to form a stable hemin-ssDNA conjugate.The AuNPs released from AussDNA would be aggregated in the condition of 50 mmol/L NaCl and exhibited a strong resonance Rayleigh scattering (RRS) peak at 367.6 nm.Under the selected conditions,the increased RRS intensity (ΔI367.6 nm) was linear to hemin concentration in the range of 5~750 nmol/L,with a regression equation of ΔI367.6 nm=2.4C-144.4,coefficient of 0.982 9,and a detection limit of 66 pmol/L.This RRS method was applied to determination of residual hemin in serum samples,with satisfactory results.The remnant AussDNA in the solution exhibited a strong catalytic activity on the Cu2O particle reaction of Fehling reagent-glucose that can be monitored by RRS technique at 370 nm.When the hemin concentration increased,the AussDNA decreased,the catalysis decreased,and the RRS intensity at 370 nm decreased.The decreased RRS intensity ΔI370 nm was linear to the hemin concentration in the range of 0.25~200 nmol/L,with a regression equation of ΔI370 nm=5.5C+78,coefficient of 0.971 9,and a detection limit of 17 pmol/L.Accordingly,a sensitivity,selectivity,and simplicity new method of resonance Rayleigh scattering spectra to detect hemin using aptamer-modified nanogold as catalyst was established.

The vascular plants of Laohutiao Nature Reserve in Guangxi were comprehensively studied.The results show that 4 vascular families belong to East Asia distribution and its variants.There is no Chinese endemic family.There are 5 Chinese endemic genera and 47 Guangxi endemic species.193 rare and endangered species are found in the Reserve.14 species belong to the key protected species of Guangxi.Reevesia multinervia Y.F.Huang,sp.nov.ined.and Odontochilus napoensis H.Tang & Y.F.Huang,sp.nov.ined.are two new species to be published.

In order to treat swine enzootic pneumonia and reduce the cost of pig breeding,and to promote the sustainable development of pig breeding,this study uses traditional Chinese medicine to do the sensitive drug trials to find out the corresponding sensitive traditional Chinese medicine,and establish the prevention and control of porcine respiratory pattern.The suspected swine which have asthma were divided into three groups,antibiotic and traditional Chinese medicine were used to do the relevant treatment respectively,and the effect of antibiotic and traditional Chinese medicine were compared.The experimental results show that,Chinese medicine treatment is better than that of antibiotics.It's obvious that using antibiotic for long time will create resistance for drugs,which will lead bad therapeutic effect,but traditional Chinese medicine is mild and had little after-affect,it will have obvious therapeutic effect and no resistance to drugs.

In order to know the soil aggregate characteristic on typical Karst soils,two Karst soils (terra fusca and rendzina) and a zonality soil (red soil) were selected with different soil organic carbon (SOC) content for study.Soil aggregates were obtained with dry sieving method and wet sieving method for soil stability (PAD,MWD,WSA) analyses.The results showed that,MWD and WSA were in order of rendzina>terra fusca>red soil(p<0.05).On the condition of the same content of SOC,red soil was the most easily to be destroyed than terra fusca and rendzina according to the result of PAD.This implied that Karst soil aggregate mechanical stability was better than that in red soil,and the resistance of soil erosion caused by rainfall resistance in Karst soils was better than that in red soil.There are significant differences between Karst soils and red soil,and it is closely related to SOC.From the point of view of soil aggregate,it benefits the stability of Karst soil SOC.
