According to 3GPP latest standards, we give specific analysis of the AM (confirmed) mode data transmission process and the process of the function in this article, then we focusing on how to design and achieve PDCP(Packet Data Convergence Protocol ) confirmation mode based on the practical application . Including system design, primitive design and memory management, as well as what need to do during the boot. Confirmation mode is truly play its role in the reconstruction process, we elaborate the reconstruction process details of the reconstruction process from the point of view of RRC (Radio Resource Control) global angle and the the PDCP local angle . The program was fully proven to meet the requirements of the LTE system.

The article focuses on the task of measuring and evaluating a state's soft power. While the soft power concept developed by Joseph Nye is currently widely accepted and used, its theoretical understanding and practical application remains challenging. Both international relations scholars and those responsible for soft power in governmental and non-state agencies are looking for the tools to assess their work and the country's standing in the world in terms of soft power. As the author of the concept and other researchers noted, evaluation and measurement may be difficult due to the number of influencing factors including the use of hard power that can overshadow soft power efforts, and also because soft power efforts can bring results only in a distant period of time. However, in response to the researchers' and policy makers' need to evaluate, measure and compare soft power related parameters, a number of international ratings evolved during the past several years, such as various ratings of soft power, nation brands, countries' reputation and presence. At the same time, such rankings have several weaknesses. First of all, they present mainly the western point of view which focuses on the parameters important for western audiences and may overlook characteristics important for other, non-western cultures. They also may be subjective due to financial reasons. Besides that, while some of the ratings aim to evaluate resources or assets of nations' soft power, other focus on results like influence or reputation. Evaluation of instruments used to enhance a country's soft power and their effectiveness is also important. In many cases, even significant resources of soft power do not guarantee strong positions in this context. Comparing certain countries' positions in different ratings helps to understand a country's standing in terms of soft power, identify strong sides and analyze whether a state's soft power potential transforms into the desired outcomes.

The «square array» is what we may consider to be an unconventional geoelectric configuration since it is not widely used and therefore there are few examples of practical application. The purpose of this research was to verify the operating effectiveness of this configuration in terms of profile and sounding, and the significance of the set of possible measurements and derived parameters. This was also obtained by comparing the relative measurements with the most common linear arrays (Wenner, Schlumberger, tripotential). The experiment was carried out in two different zones. In the first area, corresponding to the archaeological site of Marzabotto (Bologna), the target was represented by wall remnants inserted in a substantially homogeneous medium, from an electrical point of view, and at depths that are less than those of the dimensions of the device used. At the second site, located in the valley of Landrazza (Savona), the situation was very different, with a valley section on a calcareous bedrock filled with poorly classified residual sediments. An overall analysis of the results showed that the square technique is more exhaustive than the classical linear arrangements when performing soundings. Instead, with regard to profile development, it is not as preferred since it involves a greater amount of work without generating improved information. From analysis of the experimental results, considerable doubts arose about the meaning and the use of the anisotropy coefficients and the error term as defined theoretically. These parameters turned out to be of little use with regard to the characterization of the ground anisotropy and for checking the reliability of the measurements.

In this paper, we have analyzed and developed different types of algorithms related to 5G accessibility procedures for Non Standalone (NSA) and Standalone (SA) mode. The 5G accessibility depends on 5G radio parameters of each procedure, such as contention based Random access (CBRA), contention free random access (CFRA), Radio admission control (RAC), Radio resource control (RRC) and Radio bearer reconfiguration. The random access procedure for NSA is similar to SA mode. The goal is to improve the accessibility by optimizing timers and tune the main 5G radio parameters related to Random access channel (RACH), RRC reconfiguration and RAC procedures.

This chapter deals with jumping. Jumping, as it has evolved in competition recently, rarely has direct practical application, but the educational value of the sport is tremendous. Jumping fosters bravery, dexterity, courage, and a strong spirit, all of which results in a ski jumper's acquisition of self-confidence, composure, and resourcefulness—traits that are crucial while skiing over varied terrain. In addition, the skier experiences enjoyment and pleasure after the completion of a successful jump. To that end, the chapter takes a look at jumping exclusively from an athletic point of view. Here, it illustrates the proper techniques for a beautiful and successful jump and takes note of any possible mistakes which might be incurred.

In order to verify the protocol conformance of radio resource control (RRC) connection reestablishment in LTE system, a new testing method is designed by implementing testing and test control notation version 3(TTCN-3) abstract test suit. Furthermore, the test suit is operated on the TTworkbench developed by German Testing tech. It also generates graphical presentation format (GFT) to check the protocol conformance of RRC functions. The scheme has been successfully applied in the project development of TTCN extended test set instrument in LTE system.
