Set Up

A method for the quantitative determination of the major constituents in laterites and bauxites by x-ray fluorescence using fused Na2B4O7 glass discs is presented. The calibration curves were set up employing synthetic mixtures of oxides of Si, Al, Ti, and Fe. The interelement effects were corrected using a multiple regression analysis programed on a PDP 11/45 computer. The precision was determined by preparation and analysis of five synthetic pellets; the accuracy was ascertained by analysis of five international standards.

Quality Grading

We study the implementation of a meat-quality grading system, using the concept of the marbling score, and image processing, neural network techniques and multiple regression analysis. The marbling score is a measure of the distribution density of fat in the rib-eye region. We identify five features used for grading meat images. For the evaluation of the five features, we propose a method of image binarization using a three-layer neural network developed based on inputs given by a professional grader and a system of meat-quality grading based on the evaluation of three of five features with multiple regression analysis. Experimental results show that the system is effective.

Purposive Sampling

This research conducted to determine the effect of service tax officials, penalties for late-payments and reporting on the taxpayer compliance non-star hotels. This research was conducted at Dinas Pendapatan Kota Batam. Mechanical determination of sample using a purposive sampling technique with a total sample of 116 taxpayers. The type of data used is primary data. Methods of data collection are done by questionnaire. Data using multiple regression analysis with SPSS V.20.0. These results indicate that the service tax officials, penalties for late-payments and reporting have a positive and significant effect on the taxpayer compliance non-star hotels. The limitations in the study are the lack of understanding of respondents to the statements in the questionnaire and caring attitude and seriousness in answering statements. The study also suggested that Dinas Pendapatan Kota Batam provides socialization with both the taxpayer so they better understand the tax penalties and cause sanctions fines on taxpayers.

The purpose of this research is to determine the effect Admission and Determination of Rates Levy Heritage simultaneously and partially on the level of revenue. The population in this research is a report on actual revenues levies, tariffs sights and Local Revenue 2013-2015 period. The sampling technique used purposive sampling technique. The data in this research will be tested using statistical test, classic assumption test, and analyzed using multiple regression analysis. The results showed that Levy Admission and Determination of Rates Heritage simultaneous positive effect on regional revenue. P-value was 0,000. This means shows that the p-value is smaller than a predetermined level of 5%. In t test, it was concluded that the Levies Revenue partially positive effect on regional revenue. Because it is known that p-value

Experimental Parameters

The role of statistics in certain areas of X-ray fluorescence analysis is considered. The topics discussed include: calculating the standard deviation associated with the result of an analysis; optimizing experimental parameters for both wavelength and energy dispersive analyses; evaluating limits of detection, limits of decision, and limits of determination; and weighting in the least squares fitting of data in single element polynomial relationships and in multi-element multiple regression analysis.
