Formulation Factors

In this paper, it was analysed the influence of formulation factors over obtaining oxicam hydrogels, using the statistical analysis. Data analysis and predictive modeling by multivariate regression offers a large number of possible explanatory/predictive variables. Therefore, variable selection and dimension reduction is a major task for multivariate statistical analysis, especially for multivariate regressions. The statistical analysis and computational data processing of responses obtained from different pharmaceutical formulations, via different experimental protocols, lead to the optimization of the formulation process. It was found that the most suitable pharmaceutical formulations based on oxicams with the possibility of rapid release contained cyclodextrin, in particular 2-hydroxypropyl-b-cyclodextrin.

Financial literacy is one of the key components of education for living in a modern society. In this article, we present the results of our research into the current state of financial literacy among university students from two European countries. Our research was conducted in the form of a questionnaire survey. In the first part of the questionnaire we investigated selected personal characteristics of respondents and the second part was devoted to knowledge in different areas of financial literacy. The knowledge questions were focused mainly on respondents’ competence in specific practical situations. The obtained data were processed by statistical analysis, including the dependencies between the results of the knowledge part and the self-reflexive assessment in the first part of the questionnaire. This analysis revealed several noteworthy findings. Keywords: Financial literacy; questionnaire survey; statistical tests;

Day Of The Week

The frequency of births by day of the week has been reported by several studies without a formal statistical analysis. Births occurring on weekends have been consistently found to be less frequent than births on weekdays. In this study, we compared different statistical methods to assess the effect of the day of the week on the timing of births. We employed two statistical methods, two-way ANOVA and two-way Friedman's test, to analyze the daily variations of 222,735 births from 2005 to 2007 in Harris County, Texas. Both of the statistical tests indicated that births were not uniformly distributed by day of the week. Pairwise comparisons demonstrated that the births occurring on weekends were significantly less frequent than births occurring on weekdays. Our study together with other empirical studies would provide useful information for improving hospital management and the health of infants and their mothers.

The independent variable is early detection training for posyandu craders, with an interval scale. Dependent Variable, namely Knowledge and Skills About Motor Stimulation. The instruments used were questionnaires and observation sheets, with an interval scale. Statistical analysis using the T- Test on the effect of early detection training on the development of posyandu cadres to knowledge of motor stimulation with a value of p = 0.000 means at 5% alpha. This showed that there was an effect of early detection of growth and development training for posyandu caders on knowledge of motor stimulation. The results of statistical tests showed that the value of  p = 0.000 means that at 5% alpha. This showed that there was an effect of early detection of growth and development training for posyandu caders on skill of motor stimulation. So that it  an increased of  21.33 % and 19,04 %.

The Given

For a stream cipher to be secure, the keystream generated by it should be uniformly random with parameter 1/2.Statistical tests check whether the given sequence follow a certain probability distribution. In this paper, we perform a detailed statistical analysis of various stream ciphers used in GSM 2G,3G, 4G and 5G communications. The sequences output by these ciphers are checked for randomness using the statistical tests defined by the NIST Test Suite. It should also be not possible to derive any information about secret key and the initial state ofthe cipher from the keystream. Therefore, additional statisticaltests based on properties like Correlation between Keystreamand Key, and Correlation between Keystream and IV are also performed. Performance analysis of the ciphers also has been done and the results tabulated. Almost all the ciphers pass thetests in the NIST test suite with 99% confidence level. For A5/3stream cipher, the correlation between the keystream and key is high and correlation between the keystream and IV is low when compared to other ciphers in the A5 family.

AbstractData from Norwegian glaciers and statistical tests are presented which suggest that vertical net-budget gradient, ablation gradient and equilibrium-line altitude can be taken as characteristic for any particular glacier. The usefulness of these conceptual models as predictive techniques for the regional determination of glacier net budget when only a small sample is available, and in palaeo-net-budget studies, is shown to be limited.
