Code inspections and structural unit testing are two common defect detection methods in software development. This paper analyzes three replications of an experiment aimed at comparing which method finds more defects. The first two experiments use the same experimental design and materials, including the programs to be inspected or tested, while the third experiment replaces the programs with code...
The methods of documentary data collecting, mathematical statistics as well as the grey weight analysis in the grey theory system are used to analyze the influencing factors in the 400m performance. Results indicate that: the time used in the first and fourth 100m of the race exerts great influence for the final result. Therefore, the training method needs to be improved in order to raise the competitiveness...
The objective of this study was to investigate how different motivational components of social cognitive theory relate to students' use of cognitive and metacognitive learning strategies in web — based autonomous English learning (WAEL). University students (n = 140) completed a survey that assessed their task value and self-efficacy, as well as outcome variables that included their use of three self-regulated...
A quantitative determination of the total alkaloid in Corydalis Ochotensis Turcz was established by acid dye colorimetry. The effects of wavelength, pH of the phosphate buffer and the quantity of acid dye were studied. Two different dyes were compared according to the yield of berberine hydrochloride. The method with bromophenol blue dye was proved to be more accurate, more stable with good reproducibility...
The study was to find the grey correlation between the performances and 10 disciplines of men's decathletes with the help of the grey relational analysis. Data in the form of scores for 192 performances in the decathlon over 8500 points was collected and then subjected to grey relational analysis. The results indicate the 10 disciplines, can be classified into five factor sets, which the Percent Contributions...
Recently, the development of the private enterprises attracts more and more concerns from all over the society, many private enterprises use diversification strategy to make enterprises bigger and stronger. This paper based on the Resources Based View and Transaction Cost Theory, from the aspects of micro, medium and macroscopic, analyze the diversified behavior of shenzhen and shanghai exchanges...
Project similarity analysis is an important link of fund project review, it can not only to declare project review rechecking, still help project applicants promptly have the research content relevant progress and avoid duplication. This paper mainly studies the project similarity model in fund project review. With the actual experience of fund project management, based on the author's knowledge set...
Abstract-Previous studies suggested that 95% of Chinese consumers had come across green advertisements and they reacted well to those ads. This paper based on attribution theory investigates the effect of green ad appeal strategy (ad types and green appeal strength) to consumer's attribution and attitude by the format of 2*2 experimental designs. The consequence indicates that consumer's attribution...
This work presents a recommender infrastructure for educational material that is described with metadata. For its operation we propose the use of the OBAA standard, an extension to IEEE LOM that provides interoperability among hardware platforms. We also suggest the need in reusing the user profiles information that are available through FOAF metadata and extend them with personalized educational...
Corrosion damage is very critical in the aircraft structure, especially in the highly corrosive marine environment. To better assess the residual strength and more accurate predict the life extension for aircraft structure, the corrosion test for any new aluminum alloy is an essential step. In this paper, different statistical analysis methods are employed and compared to get the best corrosion damage...
This paper introduced the quality control and quality assurance tests used during high-speed railway subgrade construction by China and Germany. Through laboratory Proctor compaction tests and in-situ tests using two kinds of filling materials, the correlations between compaction grade used in China and Proctor density used in Germany are obtained. The relations among the porosity, compaction grade...
So far, there are many conclusions about the formation conditions of debris flows but most are qualitative analysis. On the basis of in-depth study of previous scientific research, this paper, combined with the actual situation of the debris flows in the Himalaya Region and selected quantitative classified indicators, using the canonical correlation analysis method based on fuzzy diagnosis, analyzes...
In contrast with traditional remote sensing, hyperspectral remote sensing has the characteristics of high spectral resolution, combination of graph and spectrum, and large quantity of imaging bands. It has been used in many fields. According to the research results of other scholars, building surface has become a thermal active surface which has an important effect for forming city three-dimensional...
Obsolescence makes equipments supporting and maintaining hard and costly. It hurts the equipments reliability seriously. In the past decades, electronic technology has developed very rapidly causing components (and particularly the FPGAs) to have a shortened life span. So the problem of electronic component obsolescence in complex electronic or long life systems such as aircraft submarines and ships...
In the present study, blindfolded subjects had to explore differently shaped objects with two hands and to judge their volume. The results showed a significant effect of the shape of objects on their perceived volume. Additional analysis showed that this effect could not be explained by the subjects' tendency to base the volume judgment on a specific object dimension other than the volume itself....
Using Alfalfa silage as research materials, the research discusses the prediction of Near Infrared Spectroscopy (NIRS) on chemical compounds 121 samples of alfalfa silage. The results are as follows: the NIRS models of DM, CP, WSC have been set up. The RPD value for cross validation and validation are all above 2.5. The results show that the NIRS can accurately evaluate nutritive value of alfalfa...
Using 42-inch plasma screens and showing four kinds of content, we experimentally evaluated the relationship between TV viewers' emotional state and selected physiological and psychological indices. Our results indicated that near-infrared spectroscopy (NIRS) and low frequency/high frequency ratio (LF/HF), representing nervous system activities, are potentially useful indices for evaluating emotional...
In the present paper we combined two different non-destructive techniques to detect the water content spatial variation in a porous material. The main goal of this work was to verify the ability of radar “early time” signals, using the proton density values measured with the unilateral NMR (Nuclear Magnetic Resonance) technique, in order to detect the spatial distribution of water in the subsurface...
In this paper the effect of loading absorbing material on the reverberation chamber is mainly discussed, including distribution function, correlation coefficient and loading factor. The absorbing material's number and location are analyzed in detail. Based on the statistics, in the reverberation chamber, a certain amount of load can improve the performance, and the different location load makes a...
As student satisfaction surveys are a primary method of evaluating university faculty teaching performance, it is essential to develop an understanding of the factors driving course evaluation. Here we discuss experiments conducted to investigate the value of various service actions in the classroom environment. In particular, we focus on the offering of excitement needs such as giving candy, humor,...
