Smooth Approximation Functions

The use of sparse data in hybrid computer simula tion has been provided with a formal procedure for generating smooth approximation functions with excellent reproduction quality. The method is use ful with data records over the independent variable or where a variable diode function generator might be used. The method depends on the theory of spline functions, which provides the specified quality of "smoothness" of the reconstructed function. An analog polynomial circuit receives parameters sequentially from the digital to generate the function. Besides illustrating an efficient method for hybrid function generation, the subject of spline approximation has been introduced to simulators in a simple language.

This study aimed at identifying the prevalence of the negative evaluation of dental services among elderly Brazilians and at investigating whether the prevalence was higher among those using public or philanthropic provider services than among those paying privately or using private health plans. Additionally, factors associated with this negative assessment were identified. Interview and survey data were collected in the residences of participants by trained and calibrated examiners as part of a national epidemiological survey of oral health conditions of the Brazilian population in 2002/2003. The dependent variable was obtained in response to questions regarding whether the participant had ever used dental services, the frequency of use, and the quality of this service. Potential responses to the questions regarding the quality of service were very poor or poor, fair, and good or very good. The main independent variable was the system of health care used with potential responses being health plan or private, public, and philanthropic services. We conducted univariate (linear tendency χ2test) and multiple descriptive analyses, and the partial proportional Odds model for ordinal logistic regression. Among the elderly, 196 (3.7%) evaluated the provided services negatively (very poor or poor). Participants with the following responses were more likely to evaluate the services negatively: those who had used public or philanthropic services, men, those with higher education, the ones who had not received information about preventing dental problems, those who perceived pain in their teeth and gums in the last six months, and those who self-reported their oral health and speech was poor. In conclusion, elderly Brazilian users of public and philanthropic services were more likely than users of private or insurance-based plans to evaluate their dental services negatively, regardless of the other investigated variables.

Basically the decision to buy bottled water by consumers is influenced by many factors such as the quality of a product, brand, taste, lifestyle and the range of promotion made by the company. Driven by the needs that exist within a person and the desire that the needs in a person are affected if the consumer shows a sense of fun that ultimately leads to loyalty. Loyal customers are more valuable than customers who are just satisfied. For loyal customers will always use the product of all time and is a source of revenue and Aicos company in this case have been concerned about factors that can affect consumers in buying decisions. In this research, the research describes several variables that influence consumer purchase decision that is product quality, price, promotion. The quality of the product, the price, the promotion is called the independent variable and the purchase decision is called the dependent variable. Through the research results obtained by researchers, the researchers drew the conclusion that the variables free of price and promotion have a significant effect on purchasing decision because the value of sig <0,05. While for the independent variable of product quality has no significant effect with purchase decision because sig value> 0,05. This is because the consumers who have been interviewed stated that the drinking water products in their quality packaging are almost the same.

This study aimed to find correlations between the quality of life, happiness, and life satisfaction of the general population of Bandung city. There were 370 participants with averageage of 20.7 years, mostly male (55.7%) and with a secondary level of education (SMP-SMA; 57.0%) who completed three questionnaires: (i) WHOQOL-BREF to measure quality of life, (ii) Happiness Thermometer to measure happiness, and (iii) Self-Anchoring Cantril Striving Scale to measure life satisfaction. Multiple linear regression tests were used with happiness and life satisfaction as dependent variables and quality of life as an independent variable. The results showed that the psychological and physical domains of quality of life were significant predictors of happiness and satisfaction of life, where the psychological domain proved significant in predicting all four-time points: happiness today (β=0.039; p<0.05), happiness throughout life (β=0.043; p<0.05), current life satisfaction (β=0.034; p<0.05) and life satisfaction five years from now (β=0.017; p<0.05). Physical domain was similar to psychological except for current life satisfaction (β=0.029; 0.023; 0.014; p<0.05). The environmental domain had been shown to predict happiness throughout life significantly (β=0.019; p<0.05) and life satisfaction five years from now (β=-0.015; p<0.05). The social domain was not found to be a significant predictor. It can be concluded that improving the psychological and physical function of Indonesian people and their environmental conditions will lead them to a happier and more satisfying life.

The water quality of subterranean rivers in the South China Karst region has undergone dramatic changes resulting from industrial and social development over the past 60 years. The combination of sampling results from subterranean rivers in four typical study areas in the South China Karst region from October to December 2015 (dry season) and correlation analysis using SPSS revealed that the main ions K+, Na+, and SO42- exhibited a significant correlation (p<0.01) and that Ca2+, HCO3-, and Mg2+ exhibited a good correlation (p<0.01). Additionally, we consolidated the data collected since 1960 and, by applying MATLAB, a variety of fitting curve methods were used to fit all the data, and the results showed that cubic spline interpolation fitting performed the best. The squared correlation coefficients (R2) of the obtained fitting curves for Ca2+, HCO3-, and Mg2+ are 0.8545, 0.8689, and 0.7632, respectively, and the corrected R2 values are 0.6739, 0.7088, and 0.4853, respectively. The R2 values of the obtained fitting curves for K+, Na+, Cl-, SO42-, and NO3- are 0.9085, 0.8964, 0.7531, 0.6222, and 0.7997, respectively, and the corrected R2 values are 0.7904, 0.7669, 0.5272, 0.2815, and 0.6127, respectively, indicating excellent fits. Based on the fitting curves, the overall water quality conditions in the karst region were analyzed and compared. Finally, the development of subterranean rivers in the South China Karst region was determined. Based on the results, the following conclusions can be drawn: the development of the subterranean rivers is indeed a slow process, but water quality can change rapidly in response to the transformation of industrial society. Additionally, the results indicate the crucial importance of urban planning that takes into account environmental protection during development in karst regions. This study aims to provide a basis for the management of karst areas and the improvement of groundwater quality by evaluating geochemical processes.

Abstract This paper discusses properties of several statistical parameters that are useful in judging the quality of least-squares fits of experimental data and in interpreting least-squares results. The presentation includes simplified equations that emphasize similarities and dissimilarities among the standard error of estimate, the standard deviations of slopes and intercepts, the correlation coefficient, and the degree of correlation between the least-squares slope and intercept. The equations are used to illustrate dependencies of these parameters upon experimentally controlled variables such as the number of data points and the range and average value of the independent variable. Results are interpreted in terms of which parameters are most useful for different kinds of applications. The paper also includes a discussion of joint confidence intervals that should be used when slopes and intercepts are highly correlated and presents equations that can be used to judge the degree of correlation between these coefficients and to compute the elliptical joint confidence intervals. The parabolic confidence intervals for calibration cures are also discussed briefly.

The purpose of this paper is to analyse whether the extent and quality of voluntarily disclosed information regarding intellectual capital (IC) are correlated with certain characteristics of a company. IC is very important for IT companies. Therefore, financial and non-financial statements of 32 high-tech companies were investigated using the content analysis method. To test the influence of firm characteristics on the intellectual capital disclosure index (ICDI), the regression model was used. The size of the firm was the only independent variable that has had a statistically significant influence on the ICDI. The auditor type, as well as financial ratios, have not shown a statistically significant influence on the extent and quality of IC disclosures. This study reflects the state regarding the voluntary IC disclosures in Croatia and therefore the study may be a roadmap for further research and, more importantly, might promote awareness of the importance of transparent reporting.
