The cleanliness of the casting blanks could seriously affect the quality of downstream products. Recently, ultrasound technology has been introduced to detect the inclusions in metal materials. However, due to the anisotropy of the material crystal, the ultrasonic wave has the characteristics of multiple scattering and refraction in its propagation process. This makes it difficult to evaluate the casting blanks cleanliness effectively, for the inclusion echoes are submerged in the background noise. Therefore, the ultrasonic microscope is innovatively proposed to carry out efficient scanning on the casting blanks. In the meantime, the morphological filtering algorithm has the advantages of fewer parameters and faster calculation speed which can be used to increase the signal-to-noise ratio of ultrasound images and extract the defect features more efficiently. In order to verify the effectiveness of the proposed method, specimens were taken from three strands of continuous caster for detection and analysis. The experimental results show that the second strand has the best quality and the cleanliness is 2.2/mm3, which is obviously better than the other two strands. This method will provide a new technology for the quantitative evaluation of the internal quality of the casting blanks.

Evaluation Techniques

Both external and internal quality of fruits such as tomatoes can be evaluated by different methods, but all most all of the methods are destructive. For this reason, there is a need to reassess some of the alternative techniques. Nondestructive quality evaluation is an attractive alternative. The principles of different nondestructive quality evaluation techniques such as optical, physical, and fluorescence techniques applied to tomato fruit is explained. Successful application of these techniques that could be used for evaluation of different quality attributes are illustrated. The advantages of nondestructive quality evaluation techniques are that they are very fast, easy, labor- and time-intensive, and inexpensive. These techniques could also be useful to evaluate the quality of other vegetables.

The Relationship

The evolution of software is necessary for the success of software systems. Studying the evolution of software and understanding it is a vocal topic of study in software engineering. One of the primary concepts of software evolution is that the internal quality of a software system declines when it evolves. In this paper, the method of evolution of the internal quality of object-oriented open-source software systems has been examined by applying a software metric approach. More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.

<p><em>One of the effects of globalization is the increase of the opportunity of work but this is accompanied by the strict competition in getting job caused by globalization so the implementation system of university should continually be able to anticipate those dynamic changes that the alumnus has the high competition level. This condition underlines the urgency of system implementation of internal quality guarantee. System implementation of internal quality guarantee was made as the basis control management of the high education quality with national standard. The process of system implementation of internal quality guarantee was not far from quality, target of education implementation quality, and all documentations of quality that mus be socialized elements of academic and institution leader to implement optimally because the important values of effort from system of internal quality guarantee if the discovery gotten, was continued by planning and application of programs for future fixes. There were some crucial urgencies gotten by university in evaluation that was done by system of internal quality guarantee, university should; 1) able to identify power and weakness as the basis of arrangement of continue plan of development. 1) able to learn the opportunity to develop the quality of education, score the success of development effort, and do adaptation of programs; 3) able to know the level of performance success based on Standard, and 4) able to supply the valid report to holder of interest about progress and result-raised.</em></p>

Laying Performance

Poultry products are the major source of animal protein for most people throughout the world and egg production is the major index of performance of commercial layer business and the avenue in the potential increase ofincome from the enterprise which focuses onegg yield, weight of eggs, and increasing their quality production to enhance economic performance.Microalgae is certainly an interesting solution, it aims to increase its value as an animal feed additive in new commercial applications. The experimental research was used in this study to evaluate the laying performance and egg quality of DeKalb under two feeding regimen such as feeding density andfrequency of microalgae paste Chlorella vulgaris under battery type cage system. The experiment was conducted in acompletely randomized designwith a period of 30 days with 81 Dekalb of the same age. The experimental diet used were commercial feeds,microalgae paste and feeding frequencies of 4 times, 3 times and 2 times.Egg characteristics such as total number of eggs, egg weight (g), egg length (mm), egg width (mm) and shape index (%) were computed based on the data from feeding frequency and density. The costs of feeds and price of grown Dekalb and some material used were used in the computation of return on investment. Based on the result, the effect on the external quality of eggs fed under different feeding densities and frequencies on egg production, egg width, egg weight, egg length and shape index resulted to not significantthe null hypothesis was accepted. The internal quality, the effect of different feeding densities on albumen height, albumen weight and yolk width also statistically not significant. Supplementation of microalgae Chlorella vulgaris on hen diet can be included as a dietary supplement for laying hens up to 80% of the diet to produce quality eggs.
