Measurement And Evaluation

A measurement on the topography and 3D roughness parameters of the ferrite surface has been taken by using a 3D optical profiler. Based on the analysis of the experimental data and the contradistinction between the ferrite devices with different quality and service performance, one preliminary conclusion has been obtained that the surface quality of ferrite materials can be evaluated by using the 3D roughness parameters, and this method is applicable and stable. With qualitative and quantitative analysis, it could be predicted that the surface quality has a direct influence on the service performance of ferrite devices.

Crack Condition

An acquisition of ferrite surface images has been taken with a LY-WN-YH Hyper-depth measurement system, from which the crack condition was analyzed with MATLAB. Based on the contradistinction between experimental data from ferrite work pieces of different quality, a preliminary conclusion has been drawn that the surface quality of ferrite materials has a direct link to the quantity and length of the crack on them. By measuring the quantity and length of the crack, an initial criterion was obtained for judging the surface quality of ferrite.

The quality of underwater images is an important problem for resource detection. However, the light scattering and plankton in water can impact the quality of underwater images. In this paper, a novel underwater image restoration based on non-convex, non-smooth variation and thermal exchange optimization is proposed. Firstly, the underwater dark channel prior is used to estimate the rough transmission map. Secondly, the rough transmission map is refined by the proposed adaptive non-convex non-smooth variation. Then, Thermal Exchange Optimization is applied to compensate for the red channel of underwater images. Finally, the restored image can be estimated via the image formation model. The results show that the proposed algorithm can output high-quality images, according to qualitative and quantitative analysis.

Business process outsourcing (BPO) is transforming Western companies’ corporate real estate (CRE) requirements. When business processes move to a developing country there are consequences for that country’s CRE practice. This paper considers the effects of western BPO on Indian CRE. Qualitative and quantitative analysis was used to analyze data from a survey of professionals operating in Indian CRE. Location issues, quality of workspace, and the availability of human resources were identified as important in establishing BPO activities in India. Suburban, and campus or built-to-suit facilities, were increasingly preferred locations and styles of workplace that were transforming Indian CRE practice. Also, the effect of western BPO was impacting on the types of CRE services being offered. With the continuing growth in BPO to ‘secondary cities’ the transformational effects on local CRE practice are likely to spread and further transform CRE practice in India.

Factors Of Influence

This paper presents the study of the influence of cutting parameters on surface quality in laser cutting of metallic materials. In this paper, it is shown which of the cutting parameters have the greatest influence on the quality of the processed surfaces by measuring various roughness parameters. After the experimental research was carried out a ranking of the factors of influence on the response functions was made, also graphs of dependency to various parameters of roughness were made.

The Relationship

As the inductance of magnetic cores is the most important parameter for their service performance. Four coupling models of EE-type ferrite cores are established to analyze the relationship between surface quality and the inductance of ferrite cores. Besides, 3D FEM simulation of different models is made by ANSOFT MAXWELL software. The results show that the surface quality has a direct influence on the service performance of ferrite devices.

Research Findings

In this article, the problems of dubbing, especially related to lip synchrony as one of the most challenging aspects of audiovisual translation, are scrutinised. Contrarily to the traditional focus on bilabials and open vowels, the object of this research is lip synchrony of both rounded and protruded vowels and diphthongs since lip rounding is a visibly marked feature, which cannot be neglected especially in close-ups. The study aims at determining the inaccuracies in lip synchrony of the mentioned phonemic group in the dubbed animated feature film Cloudy with a Chance of Meatballs 2 from English to Lithuanian. Qualitative and quantitative analysis is carried out by employing a comparative method. The research methodology is based on the theoretical insights and assumptions provided by Frederic Chaume (2004, 2006, 2012), Richard Barsam & Dave Monahan (2010), and Indrė Koverienė (2015). The research findings demonstrate the main issues of lip synchrony a translator might face while adapting a piece of audiovisual material for the target language audience. Also, it provides insights into the quality of the overall translation of the chosen film.

The low scientific literacy of Indonesian students indicates the low quality of science/science education. Reality on the ground in the science learning process is that teachers only use textbooks and have not developed inquiry labs-based teaching materials. The research objective is to develop an integrated science teaching material based on inquiry labs that is valid, practical, and effective. The type of research is research and development (r&d). The test was conducted in class VIIB of MTsN 6 Sijunjung. The instruments used are expert validation sheets and student questionnaires. The data analysis technique used in this research is qualitative and quantitative analysis. The results of the validation of teaching materials have an average value of 89, meaning are very valid. The average practicality test results for teaching materials are 84, meaning are very practical. The results of statistical tests on students' scientific literacy tests were effective in increasing students' scientific literation

Like any other food/feed matrix, regardless of the employed analytical method, wine requires authentication strategies; a suitable qualitative and quantitative analysis represents the fingerprint which defines its identity. Until recently, fingerprinting approaches using liquid chromatography applications have been regarded as an effective tool for the assessment of wines employing polyphenol profiles. These profiles are of considerable importance for grapes and wines as they influence greatly the color, sensory, and nutritional quality of the final product. The authenticity and typicity characters are fundamental characteristics, which may be evaluated by the use of polyphenol fingerprinting techniques. Under these conditions, the evolution of polyphenols during the red wine elaboration and maturation processes shows a high importance at the level of the obtained fingerprints. Moreover, the environment factors (vintage, the area of origin, and variety) and the technological conditions significantly influence wine authenticity through the use of polyphenol profiles. Taking into account the complexity of the matter at hand, this review outlines the latest trends in the polyphenol fingerprinting of red wines in association with the transformations that occur during winemaking and storage.
