As we all known, information security has become an important affecting factor about the development of information technology. Toefficiently ensure the information security, it is necessary to take regular evaluation for the security situation of information system. However, the basis work of evaluation index system is less scientific and measurable. According to the essential demand of information system security level protection（ISSLP） and the present information security status of the company system, in this paper, firstly, the evaluation index system of ISSLP is systematically constructed andindividual evaluation indexes are objectivelyclarified. Then, by analytic hierarchy process and subjective estimate method, the weight of these indexes is determined. Finally, the calculation method, which is able to reflect information security situation and the weakest security link of system, is expounded to quantify individual evaluation and comprehensive evaluation. What is more, the experimental result on real data shows that our method is performance more nice, which can provide a new thought in the aspect of information security evaluation work.

Machine vision is widely used in automatic equipments, but the vision system based on embedded Linux is seldom at present. The key points and difficulties are the image processing and its realtime on embedded system. This paper introduces the vision processing system based on ARM and Linux, mainly introduces the USB camera driver, image matching, camera calibration and object localization. Comparing the conventional method using PC with universal software, vision processing system based on ARM and Linux greatly reduces the system size and cost. Experimental results show that this system can accurately recognize and locate the target object. The efficiency can meet the requirement basically, and it still has room to improve.

The use of web services has been growing significantly, with increasingly large numbers of applications being implemented through the web. A difficulty associated with this development is the quality assurance of these services, specifically the challenges encountered when testing the applications - amongst other things, testers may not have access to the source code, and the correctness of the output may not be easily ascertained (known as the oracle problem). Metamorphic testing (MT) has been introduced as a technique to alleviate the oracle problem. MT makes use of properties of the software under test, known as metamorphic relations, and checks whether or not these relations are violated. Since MT does not require source code to generate the metamorphic relations, it is suitable for testing web services-based applications. We have designed an XML-based language representation to facilitate the formalisation of metamorphic relations, the generation of (follow-up) test cases, and the verification of the test results. Based on this, we have also developed a tool to support the automation of MT for web service applications. This tool has been used in an experiment to test web services, the evaluation of which is reported in this paper. Copyright © 2016 Inderscience Enterprises Ltd.

The investigation of the positive impact of using artificial intelligence systems in meteorological satellite images classification is presented in this study. An application for classifying clouds observed northern Algeria by the MSG (Meteosat Second Generation) satellite is developed in this work. The proposed identification system is based on the spectral information derived from the infrared channels of MSG satellite images. The classification aim is to identify pixels as rainy or not, and to delineate precipitating areas for northern Algeria in real time. An SVM (Support Vector Machine) classifier is adopted in this work as the intelligent system used for the identification. Models are trained and validated against in situ rainfall measurements, collected during the rainy period of the year 2012, by automatic rain-gauge stations distributed over the study area (North of Algeria). Five statistical assessors are used to evaluate performances. Results of the classification by the SVM are compared to a statistical method, based on thresholding in histograms representing classes' features. The classification error has been significantly reduced when using the SVM classifier, allowing a more accurate estimation of precipitations by infrared MSG satellite images.

On August 17 th , 2012, a diode rectifier at Nagano Traction Substation was broken. The broken rectifier was dismantled and investigated in detail and, as a result, it was estimated that the overvoltage caused by the thunder lightning caused the dielectric breakdown in the rectifier. To confirm the assumption of the broken process, the field measurement at Nagano Traction Substation and FDTD (finite-difference time-domain) calculation analysis at Nagoya Institute of Technology were carried out. As a result, it was indicated that the direct lightning to the elevated bridge over the substation caused the transient overvoltage of the grounding system of the substation and resulted in the breakdown within the rectifier. Because the concrete bridge pier is located adjacent to the substation, the surge voltage from the elevated bridge is able to influence on the potential of the substation mesh. In this paper, the investigation process to determine the cause of the trouble will be shown in detail.

作者： Dandan Wang Yantai Nanshan University

Under the developing trends of population aging and old aging, China is trying to establish an endowment pattern of "with family endowment as the basis, with community endowment as the reliance, and with institutional endowment as the support". Compared with other endowment patterns, endowment institutions possess the features of specialization and standardization, and the most important factor to evaluate endowment institutions is the quality of service. In this thesis, GAP model will be adopted to analyze the sources of quality problems which exist in endowment institutions' long-term care service from the perspective of five sources of service quality gap, and the preliminary countermeasures will also be proposed. According to the "Statistical Bulletin of Social service Development in 2013 " issued by Ministry of Civil Affairs, by the end of 2013, all over the country, the number of elderly population over 60 years old was 202.43 million, accounting for 14.9% of the total number of population. Among them, the number of elderly population over 65 years old is 131.61 million, which accounts for 9.7% of the total number. All together, there were 42,475 endowment service institutions, and 4.937 million beds in China, 18.9% higher than 2012. Compared with other endowment patterns, endowment institutions possess the features of specialization and standardization. In the endowment institutions, the long-term endowment care service system, whose starting points are the demands of elderly people and whose duration time is longer than six months, is formed by comprehensive long-term care service-oriented architectures, including basic long-term endowment care service（such as care for catering and daily life, health care service, psychosocial service, etc.）, long-term endowment care human resources, long-term endowment care service system, and long-term endowment care policy support. The core evaluation index of long-term endowment care service system is its service quality
