Software Testing Process Evaluation with Quality Index

Advances in Communication Technology——2011 3rd World Congress in Applied Computing, Computer Science, and Computer Engineering (ACC 2011)

作者： Atanas Atanasov Liu Qin School of Software Engineering Tongji University

A major component of the evaluation of a software testing process is the correct and meaningful synthesis of the gathered information. The focus of this literature review is to summarize definitions of a quality index for the evaluation of software testing. These definitions are created with the usage of different mathematical and statistical methods. The approaches that are being scrutinized in this paper are independent from the software development model, product's domain, organization's structure or size. In addition, the approaches explained in this paper do not require any special knowledge or background for their implementation in a software organization.

Land degradation has a major impact on environmental and socio-economic sustainability. Scientific methods are necessary to monitor the risk of land degradation. In this study, the environmental sensitive area index(ESAI) was utilized to assess land degradation sensitivity and convergence analysis in Korla, a typical oasis city in Xinjiang of China, which is located on the northeast border of the Tarim Basin. A total of 18 indicators depicting soil, climate, vegetation, and management qualities were used to illustrate spatial-temporal patterns of land degradation sensitivity from 1994 to 2018. We investigated the causes of spatial convergence and divergence based on the Ordinary Least Squares(OLS) and Geographically Weighted Regression(GWR) models. The results show that the branch of the Tianshan Mountains and oasis plain had a low sensitivity to land degradation, while the Tarim Basin had a high risk of land degradation. More than two-thirds of the study area can be categorized as "critical" sensitivity classes. The largest percentage(32.6%) of fragile classes was observed for 2006. There was no significant change in insensitive or low-sensitivity areas, which accounted for less than 0.4% of the entire observation period. The ESAI of the four time periods(1994–1998, 1998–2006, 2006–2010, and 2010–2018) formed a series of convergence patterns. The convergence patterns of 1994–1998 and 1998–2006 can be explained by the government's efforts to "Returning Farmland to Forests" and other governance projects. In 2006–2010, the construction of afforested work intensified, but industrial development and human activities affected the convergence pattern. The pattern of convergence in most regions between 2010 and 2018 can be attributed to the government's implementation of a series of key ecological protection projects, which led to a decrease in sensitivity to land degradation. The results of this study altogether suggest that the ESAI convergence analysis is an effective e

Numerous satellites collect imagery of the Earth’s surface daily, providing information to the public and private sectors. The fusion (pan-sharpening) of high-resolution panchromatic satellite imagery with lower-resolution multispectral satellite imagery has shown promise for monitoring natural resources and farming areas. It results in new imagery with more detail than the original multispectral or panchromatic images. In agricultural areas in Mississippi, landscapes can range from complex mixtures of vegetation and built-up areas to dense vegetative regions. More information is needed on pan-sharpened imagery for assessing landscapes in rural areas of Mississippi. WorldView 3 satellite imagery consisting of landscapes commonly found in rural areas of Mississippi was subjected to 17 pan-sharpening algorithms. The pan-sharpened images were compared qualitatively and quantitatively with three quality indices: 1) Erreur Relative Globale Addimensionelle de Synthese;2) Universal Image quality index;3) Bias. à trous wavelet transform with the injection model 3 and hyperspherical color spaced fusion methods were ranked among the best for maintaining image integrity for qualitative and quantitative analyses. The optimized high-pass filter method was often ranked last by the quality indices. The smoothing filter-based intensity modulation algorithm and the gaussian modulation transfer function match filtered with high-pass modulation injection model added artifacts to the images. Pan-sharpened satellite imagery has great potential to enhance the survey of Mississippi’s agricultural areas. The key to success is selecting an image fusion process that increases spatial content while not compromising the image integrity.

The term ＂biogenic amines＂ defines decarboxylation products such as histamine, putrescine, serotonin, tyramine, phenylethylamine, tryptamine and also aliphatic polyamines. They can be detected in both raw and processed foods. In the recent years, there is a great interest in biogenic amines as they are associated with quality, safety and freshness of some foods, particularly fermented foods. The presence of biogenic amines in foods can also be used as an indicator of hygienic quality. Biogenic amines also cause health hazards due to their toxic effects especially in sensitive individuals. It is therefore important to control and reduce the biogenic amines. The reduction can be brought about by the use of high pressure, irradiation, packaging, additives, starter cultures and by reduction of decarboxylase activity and temperature. This review summarizes the significance, function, occurrence and formation of biogenic amines in different foods and their reduction by different methods.

The leaf yellowing stage in tobacco curing reduces the fragrance of the product. To solve this problem, this study introduced the principle and key parameters of a three-stage six-step curing technology. Compared with the traditional three-stage curing technology, the three-stage six-step curing technology produces more suitable ratios of chemical constituents, higher aromatic component content, and higher smoking quality grade of tobacco leaves. The continuous improvement of corollary equipment and matching technologies is expected to widen the applications of the three-stage six-step curing technology in tobacco and provide a strong technical support for the development of the tobacco industry.

＜正＞High cost and deficiency of primary material are specific factors to wool *** is higher in its cost than other principal types of textile *** this context designing an efficient wool processing technlolgy in order to use the raw material base more rationally and to increase the intensity of technlolgical processes of practical significance. In this connection a series of measures have been taken enabling to improve production diversification and reduction of woolen goods *** measures are aimed at creation of waste-free technologies involving fibres disintegration,dedusting,cleaning and formation of yarns of low and medium linear density from blends containing fibres regenerated from spinning,weaving and clothing industry wastes. The efficiency of technlolgical processes is determined not only by the appropriate adjustment of the equipment but also by changing the properties of the fibres being processed through local treatment of the product by emulsions and auxiliary textile solutions. The results of the research will make it possible to regulate characteristics of the product during its processing,to improve stability of technlolgical processes and to increase the yield of yarns the blend due to the fact that the initial properties of the fibres have been preserved.
