ADVANCEMENTS IN TAILLESS AIRCRAFT TECHNOLOGY: A COMPARATIVE ANALYSIS AND PROPOSAL FOR COMMERCIAL IMPLEMENTATION

The military has a problem in developing the most sophisticated flying wings due to the relevance of tailless aircraft in military applications and the ongoing advancements in the aviation sector. This study paper delves into the extensive history of tailless aircraft, covering everything from their inception to the most cutting-edge designs available today. To develop in control systems, especially fly-by-wire technology, tailless designs are now more practical for commercial use since they are more stable and easier to handle than they were in the past. The main goals of this research are to assess the current literature on important parts of tailless aircraft technology and provide a thorough plan for their commercial deployment.The improved splitter increases the velocity by 40 m/s, although the obtained maximum velocity distribution across the aircraft was 29.3 m/s at the rear end. As a result, the aircraft is designed with higher lift and reduced drag, allowing for smoother flight in a variety of applications.Around 53% of the lift force generated is enhanced by redesigned designs. Based on the results of the study, the aircraft with the improved design had a higher lift force and reduced drag by dividing the airflow.

Corporate Network Segmentation to Security Level Improving

The aim of the bachelor thesis is Corporate Network Segmentation to Security Level Improving. During the audit of the company's network, several problems were identified, such as a single network, weak nodes, no backup channel, a separate strand with Lithuanian servers, HQ branch without a backup channel. The most popular network security threats and attacks were reviewed, DiD strategies and measures were introduced, an audit of the existing computer network was performed, and the new network topology was drawn. Based on the Cisco PPDIOO model, a plan for gradual restructuring in a new network has been drawn up. A central device was installed in the DC of Latvia, an IPsec tunnel was agreed with the DC of Lithuania, tests were carried out. All branches were provided with backup channels, which made it possible to test a new network first through the backup channel and only when all the tests were performed and were positive, the main channel could easily be connected as well. The backup channel routers and branch routers are configured according to a single template to allow easy interchangeability. Configured access to branch switches and backup routers from both channels: primary channel and backup channel. The network has been tested and is working.

Development of a Presentation Generation Web Service Using AI Language Models

This bachelor's thesis presents the development of a presentation generation web service using AI language models. The application integrates APIs such as OpenAI for text generation, Pexels for image retrieval, and Google Slides for presentation creation, providing a comprehensive tool for generating high-quality presentations and videos. The backend is built using Flask, and the frontend uses React, ensuring a seamless user experience. Key features include user authentication, state management, and dynamic content generation.The project involved analyzing existing AI-powered presentation tools, developing the web service with frontend and backend technologies, and integrating various APIs to enhance functionality. Rigorous testing ensured stability, efficiency, and user-friendliness. The resulting application can generate high-quality presentations and convert them into engaging videos with minimal effort.This thesis demonstrates AI's potential in enhancing digital content creation, offering significant improvements in efficiency and user engagement. The developed web service provides a valuable tool for users needing to quickly create professional presentations.
