This study analyses consumer visual responses to store design elements using eye-tracking technology, focusing on identifying behavioural patterns across different age and gender groups. The primary goal was to assess how consumers respond to various aspects of the retail environment, such as price tags, promotional banners, and checkout zones. Statistical tests (Mann-Whitney U, ANOVA, and T-test) indicated no statistically significant differences between the groups observed, suggesting a need for an expanded sample size for more precise analysis and a deeper understanding of these interactions.

GNSS spoofing is a technique used to deceive Global Navigation Satellite Systems (GNSS) receivers by broadcasting fake signals that appear to be genuine. To detect GNSS spoofing, a receiver can use various techniques such as monitoring signal strength, cross-checking data from multiple satellites, comparing the signal characteristics with the expected patterns, and analyzing the timing and location information. Advanced detection methods may use machine learning algorithms to identify anomalies and patterns in the signal data. In addition, the use of encrypted signals and multiple frequency bands can make spoofing more difficult, and the implementation...
