Development of structural schemes for collecting monitoring and diagnostic data of signaling points of the railway run based on programmable logic controllers

The article talks about the problems and shortcomings of collecting various diagnostic data at signal points of existing dispatching control systems of railway automation. As a solution to these problems, structural schemes for collecting analog and discrete diagnostic data have been developed based on a programmable logic controller. On the basis of the developed structural schemes, tests were conducted on measuring voltages in two types of analog signals, and the results of the dependence of the mean square deviation on the request time in determining the effective value of the voltage were give

RELATIONSHIPS BETWEEN FINANCIAL MARKETS AND INTEREST RATES

This paper investigates the multi-scale relationship among interest rates, exchange rates, and stock prices using wavelet transform analysis. Specifically, we employ the maximum overlap discrete wavelet transform (MODWT) on interest rates, exchange rates, and stock prices in the US from January 1990 to December 2008. We utilize wavelet variance, wavelet correlation, and cross-correlation definitions to examine the association and lead/lag relationships between these series across various time scales. Our findings indicate that the relationship between interest rates and exchange rates is not significantly different from zero across all scales. Conversely, the relationship between interest rate returns and stock index returns is significantly different from zero only at the highest scales. The analysis sheds light on the dynamic interactions between these financial variables at different frequencie

THE INFLUENCE OF PRICE PERCEPTION, BRAND IMAGE, AND PRODUCT QUALITY ON BUYING INTEREST IN IPHONE SMARTPHONE PRODUCTS (A STUDY ON CONSUMERS IN SIDOARJO)

General Background: The rapid advancement of technology has significantly impacted consumer purchasing decisions, particularly in selecting smartphones. Consumers often consider factors like brand image, price perception, and product quality when choosing products. Specific Background: Among the vast range of smartphone options available, iPhone is a prominent choice, but the specific factors driving consumer interest in iPhone products, particularly in Sidoarjo, remain underexplored. Knowledge Gap: While much research has focused on general smartphone buying behavior, limited attention has been given to the specific interplay between price perception, brand image, and product quality in influencing buying interest for iPhones in regional markets like Sidoarjo. Aims: This study aims to examine the impact of price perception, brand image, and product quality on consumer buying interest in iPhone products in Sidoarjo, using Structural Equation Modeling (SEM) and Partial Least Squares (PLS) analysis. Results: From a sample of 110 respondents, the findings reveal that price perception, brand image, and product quality all have a significant positive effect on consumer buying interest. The R-square value of 0.700 suggests that 70% of the variation in buying interest is explained by these three variables. Novelty: This study provides novel insights into the Sidoarjo market, demonstrating that these factors substantially drive iPhone purchase interest, with brand reputation and perceived product quality playing key roles. Implications: The results highlight the importance of enhancing brand image and maintaining high product quality to increase consumer interest, which could inform marketing strategies for smartphone brands targeting regional markets like Sidoarjo. Future studies could explore additional variables influencing buying interest, given that 30% of the variation remains unexplained by the current model
