With the constant improvement of the complexity for a software system and under the vehemence of modern market competition among enterprises, it is necessary to improve the quality of the software and to reduce the developing cycle of the software. Distributed component technology is used widely because of its advantages. Three mainstream component technologies are discussed: EJB, CORBA, and COM/DCOM. EJB components can not only run at any platform, but also they can transplant totally between the application program servers. Application software architecture and object technical specification are established in CORBA, and its technical cores are a set of standard language, interface and protocol. COM is a criterion how component is updated alternately, CCM defines the operation mode of components and their customers, and DCOM is a model based on client and server, expanding COM, supporting the communication on the basis of LAN, WAN even Internet. Either EJB or CORBA or COM/DCOM will influence profoundly on our life and work styles.

In this paper, we report on the application of wavelet-based FDTD in numerical simulation of erbium-ytterbium co-doped waveguide amplifier (EYCDWA) using multi resolution analysis (MRA). The difference formulation for multiresolution time domain(MRTD) based on Daubechies wavelets is derived, and the gain characteristics of EYCDWA is simulated by MRTD. It demonstrates that this new algorithm is valid and shows good agreement with experimental results.

Occasionally, it is not possible to debug an application that contains a specific template in the development environment. While the SideLoading function can overcome this, the use of this feature poses great potential safety risks to application website sets if not appropriately applied. Many developers thus face a conundrum in deciding whether to enable this feature or not. This paper explores the characteristics and working mechanism of SideLoading applications in depth, proposes distinct boundaries about when and where this feature should be turned on or off, and offers a detailed code to illustrate how this function can be enabled and disabled in accordance with demand.

The study dealt with the practical skills possessed by technical teachers and their level of confidence in applying ICT for teaching in polytechnics in the North-East Geo-political Zone of Nigeria. It answered two research questions and tested two hypotheses. The study employed descriptive survey research design. Questionnaire was used to collect data from 100 certified and 114 uncertified technical teachers. The questionnaire which was divided into sections was validated by two experts in Industrial Technology Education from the academia. The validated copy of the questionnaire was trial tested on 25 technical teachers chosen from Plateau State Polytechnic, Barkin Ladi, Jos, Nigeria. Using the Crombach Alpha formula, the trial test gave the reliability coefficient of the instrument as 0.91. Six weeks were devoted to the administration of the questionnaire, at the end of which 209 valid copies were obtained, upon which analysis of the results was carried out. Mean and standard deviation were used to answer the research questions, while the Z-test tested the hypotheses at 0.05 level of significance. The study found that practical skills possessed by technical teachers’ in using ICT for teaching in polytechnics was moderate. It found that technical teachers had high confidence and motivation in applying ICT facilities for teaching. The study also found that a significant difference did not exist between the mean scores of certified and un-certified technical teachers on the technical teachers’ level of practical skills in using ICT for teaching in polytechnics. Similarly, a significant difference did not exist between the mean scores of certified and un-certified technical teachers on the level of confidence in applying ICT facilities for teaching in polytechnics. The study implied that for teachers’ level practical skills in applying of ICT in teaching to fall in line with expected standards, teacher training and professional development, and as well funding and provision of ICT facilities, must be given a serious consideration. This has become necessary since the teachers’ level of confidence and morale in applying ICT facilities in teaching is high. In this connection, the study suggested that there is need to train and retrain technical teachers on ICT use in order for them to effectively apply the facilities in teaching.

The hydrophobic cavity of cyclodextrin contributes to the wide applications in medicine, pharmaceutical, food, cosmetic industries, agriculture and environmental protection. Cyclodextrin glycosyltransferase (cgt) gene was able to be amplified from Paenibacillus polymyxa and inserted into vectors of pWB980. The recombinant vectors were transformed to Bacillus subtilis WB600. The results showed that cgt gene was expressed in Bacillus subtilis successfully. The optimum conditions for maximum enzyme activity were obtained at a temperature 35°C, pH 7 and quantity of inoculum 6%. Corn starch and soybean meal were chosen as carbon source and nitrogen source in the process of production. A maximum activity of the CGTase activity reached 9.2 U/mL, which is about 15-fold to that of the original strain Paenibacillus polymyxa. β-cyclodextrin is 0.104 mg/mL from 1% (m/m) soluble starch in 10 min (pH 7.0 50 oC). Cyclodextrins can form inclusion complexes with different molecules with the aid of their special chemical (molecular) structures. Physical and chemical properties of molecules can be changed after the formation of complex. This special feature enables the usage of cyclodextrins in different industry areas.

A 700MPa grade high strength roll-forming steel had been developed and used in bus lightweight. Some application cracking problems and its corresponding measures had been studied. The results showed that the present of higher inclusions (MnS, TiN, etc.) in raw materials and larger internal stresses in arc of the tubes were the main reason leading to cracking. By reducing the contents of P, S, and N elements, improving the rolling, cooling and coiling processes of the raw material and the roll-forming processes of the tubes, those problems had been fully solved.

In this paper, we propose a comprehensive data integration and quality assurance model, called CHARIOT, for agro-meteorological data. This model comprised of two modules: an intermediary module and a data quality control module. The intermediary provides users with reliable and continuous access to heterogeneous weather databases from various sources; it also solves various compatibility issues in meteorological time series data. The data quality control tool consists of a multi-layer system spanning internal, temporal and spatial data checks. These two modules combined together provide users with clean and error-free inputs for weather-driven agricultural management decisions. When applying CHARIOT to weather data for a real-life agricultural application, CHARIOT is shown to be effective in controlling and improving data quality, which in turn leads to better and more accurate agricultural management decisions.

Data warehouse is a big repository of an organization's electronically stored data. It is designed to facilitate reporting and analysis. With the tax data becomes more and more in China, building a data warehouse is necessary to meet the requirements of analysis and inspection. To build the tax data warehouse, firstly, we need to establish the uniform standards and determine the subject, then, we need to construct the data warehouse. Data mining is the process of extracting hidden patterns from data, and many data mining methods can be used. In this paper, we use the rule induction method in tax inspection and find we can improve the prediction accuracy rate of the actual tax inspection to a higher level.

The finite element analysis has been widely used in analysis of tubing string and down-hole tools characteristics. Low cost, short circle and visualization make finite element analysis possess more advantage. The paper introduces the application of finite element analysis in mechanics analysis of completion packer by establishing the finite element models, meshing and the analysis results of slips and rubber of THT completion packer. Based on the analysis, it can be got that the finite element analysis can simulate the contact analysis of slip teeth and rubber well; and the distribution of contact stress between slips and casing is uneven both in axial and circumferential; the rubber can seal effectively between the tubing string and casing, the contact stress of rubber-casing indicates that the stress distributes in linear along the axial. The stress near the loads is larger than others due to the friction between rubbers and casing.
