the use of UAV-Femtocell systems for the geolocation of mobile terminals has recently been introduced in the literature as an alternative and effective method in civil protection scenarios and applications. In this context, one of the important aspects concerns the optimization of geolocation times, bearing in mind the limited duration of the flight time of drones. this paper proposes a game theory-based approach to geolocation using UAV-Femtocell systems. A game structure is proposed in which the rules of drone movement are defined according to criteria and utility functions that are linked to the power measurements of the mobile terminals and obtained by the UAV-Femtocell systems in order to optimize the geolocation process through a series of successive rounds in which the Nash equilibria are reached.

Quantitative investment refers to securities trading strictly guided by computer algorithms. Withthe advancements in big data technology, quantitative investment has gained increasing significance in the global financial trading market. However, the current market information is complex, and product prices are influenced by various factors, making it challenging to extract effective indicators from the vast amount of market data and formulate trading strategies. To address this issue, this study proposes a forecasting model for quantitative investment based on BP neural networks and time series analysis, resulting in improved forecasting accuracy. the paper adopts the median to substitute indicators during the relevant time, homogenizing the time interval. the chosen BP neural network prediction model exhibits robust nonlinear mapping capabilities and fault tolerance. the model undergoes testing, yielding MAE and MAPE test results primarily at 0.08 and 0.03, respectively. the predicted values demonstrate a high degree of alignment with real values, showcasing an effective prediction outcome.

In this article, the authors critically analyze the existing econometric approaches to estimating gravity models of exports from the point of view of solving such problems as taking into account zero observations, bias, inconsistency and inefficiency of estimates. As a result, the authors come to the conclusion that the random effects panel regression estimation is the most preferable method for estimating the gravity export equation. this result has come from a case of Uzbekistan.

In this study, we suggest short-range, lightweight 6th subsequent generations (6 G) in-X network parts as a valuable radio concept responding to the demanding connectivity requirements of new applications like wearable control of arms equipped with robotics and critical on-body gadgets which include wireless heart pacemakers. the main requirements of ultra-high fidelity (exceeding 6 nines when) and sub-millisecond delay at all spatiotemporal contexts demand powerful radio systems contrary to fading and interference. Our study thoroughly explores technology drivers and methods for interference reduction in 6 G in-X subsidiary networks. the proposed methods include blind-repetition at pseudo-random frequency shifts and environment-aware tools for interference control through dynamic channel sharing. Additionally, we suggest two novel enhancements: real-time repeat order adaptation using current channel dynamics and preemptive packet duplication, during which subnetworks that are duplicate signals on a third channel group upon spotting possible nearby subnetwork interference. Simulations in an industrial workplace setting with mobile in-X subnetworks, by employing 3GPP-defined models, show the need for large internet connectivity, packet repeats, and environment-aware interference synchronization to achieve low packet loss percentages and sub- $100 \mu$ s delay. the suggested improvements show large packet loss rate decrease for systems with life times $\gt 2$ cycle times.
