Intrusion Detection Using Ensemble Wrapper Filter Based Feature Selection with Stacking Model

The number of attacks is growing tremendously in tandem with the growth of internet technologies.As a result,protecting the private data from prying eyes has become a critical and tough undertaking.Many intrusion detection solutions have been offered by researchers in order to decrease the effect of these attacks.For attack detection,the prior system has created an SMSRPF(Stacking Model Significant Rule Power Factor)classifier.To provide creative instance detection,the SMSRPF combines the detection of trained classifiers such as DT(Decision Tree)and RF(Random Forest).Nevertheless,it does not generate any accuratefindings that are adequate.The suggested system has built an EWF(Ensemble Wrapper Filter)feature selection with SMSRPF classifier for attack detection so as to overcome this problem.The UNSW-NB15 dataset is used as an input in this proposed research project.Specifically,min–max normalization approach is used to pre-process the incoming data.The feature selection is then carried out using EWF.Based on the selected features,SMSRPF classifiers are utilized to detect the attacks.The SMSRPF is integrated with the trained classi-fiers such as DT and RF to create creative instance detection.After that,the testing data is classified using MCAR(Multi-Class Classification based on Association Rules).The SRPF judges the rules correctly even when the confidence and the lift measures fail.Regarding accuracy,precision,recall,f-measure,computation time,and error,the experimental findings suggest that the new system outperforms the prior systems.

The Analysis of Comparison Between English and Chinese Animal Idioms

Idioms are essence of a language and a kind of special and fixed phrases or short sentences in the long period of language use.Because animals have been considered as people’s best friends for hundreds of years,people adopt different species of animals as metaphors to express all their emotions.However,due to the different national characteristics between English and Chinese,such as geographical conditions and tradition so in most cases easterners and westerners have different attitudes and understanding towards same animals,of course,some animal idioms have the same meaning.

Objective To investigate the expression of hepatocyte growth factor(HGF)and its relationship with microsatellite instability(MSI)and their influence on survival in patients with colorectal cancer.Methods Immunohistochemistry(IHC)was used to detect the expression of HGF and MSI in 98 specimens of colorectal cancer.Tumors lacking protein expression of any of the our mis-

Structural dimension optimization and mechanical response analysis of fabricated honeycomb plastic pavement slab

Because of favorable mechanical properties,deformation resistance and being conducive to environmental protection,honeycomb fabricated plastic pavement slabs are highly recommended these years.At present,most studies focus on the performance of plastic materials,however,the dimension optimization of fabricated plastic pavement slab is rarely mentioned.In this paper,an optimized geometry of the honeycomb pavement slab was determined through finite element analysis.Mechanical response of honeycomb slabs with different internal dimensions and external dimensions were explored.Several dimension factors were taken into consideration including the side length,rib thickness,the thickness of both top and bottom slabs of honeycomb structure and the length,the width and the thickness of the fabricated plastic slab.The results showed that honeycomb pavement slab with 6 cm bottom slab,12 cm top slab,18 cm side length and 6 cm rib thickness is recommended,additionally,an external dimension of 4 m×4 m×0.45 m is suggested.Then,the mechanical responses of this optimized fabricated plastic slab were further investigated.Significance of different influencing factors,including wheel load,elastic modulus of plastic material,base layer thickness,soil foundation modulus and base layer modulus were ranked.

Study on Thermal Characteristics of a Novel Glass Curtain Wall System

In order to solve the conflict between indoor lighting and PV cells in building-integrated photovoltaic/thermal(BIPV/T) systems, a glass curtain wall system based on a tiny transmissive concentrator is proposed. This glass curtain wall has a direct influence on the heat transfer between indoor and outdoor, and the operating parameters of air and water inlet temperature, indoor and outdoor temperature, and radiation intensity have a significant influence on the heat transfer characteristics of the glass curtain wall. The 3D model is established by SoildWorks software, and the thermal characteristics of the new glass curtain wall system are simulated through computational fluid dynamics(CFD) method. Thermal performance was tested under actual weather for the winter working conditions. The CFD simulation results are verified by the test results under actual weather. The results show that thermal efficiency simulation results are in good agreement with the experimental results of the new glass curtain wall system. The simulation conditions were designed by using the orthogonal method, and the significance analysis of the influencing factors of the indoor wall surface heat gain was carried out. With the increase of the bottom heat flux and the air velocity, the heat absorption of the inner wall surface increases. When the wind speed is 0.1 m/s, the heat flow on the bottom surface rises from 500 W/m^(2) to 2500 W/m^(2), and the heat flow intensity on the interior wall changes from 10.31 W/m^(2) to -29.12 W/m^(2). Under typical working conditions, the new glass curtain wall system can reduce the indoor heat load by 47.5% than ordinary glass curtain wall.
