Assessment of the technical condition of the air conditioning system of a passenger aircraft during operation

The air conditioning system is one of the most important life support systems in an aircraft, therefore the assessment of technical condition and maintenance of reliability at an appropriate level are of great importance in ensuring flight safety. Thesis evaluates the technical condition of the air conditioning system of short flight passenger aircraft. To solve the tasks, the author has developed a prototype of a short flights passenger transportation aircraft and proposed an air conditioning system scheme and calculated the structural reliability of the air conditioning system for one flight shift. This work has practical application and the approaches described can be used to assess the reliability and technical condition of the aircraft during exploitation.

Comparative analysis of RPL protocol objective functions impact on energy consumption in low-power and lossy networks

This bachelor thesis explores the impact of different RPL protocol objective functions on energy consumption in low-power and lossy networks. Given the critical role of low-power and lossy networks in applications like environmental monitoring, industrial automation, and smart cities, optimising energy consumption is paramount. Using the Contiki-NG operating system and the Cooja network simulator, this study conducts a comparative analysis of two primary objective functions: Objective Function Zero and Minimum Rank with Hysteresis Objective Function. Simulations are performed under 18 network scenarios including different node densities (10, 30, 50), node positioning, and receive ratios. The findings indicate that Objective Function Zero generally consumes less energy, particularly in high-density networks and environments with high packet delivery ratios. Conversely, Minimum Rank with Hysteresis Objective Function may be more suitable for dynamic and unpredictable environments despite its higher energy consumption. This research offers practical recommendations for selecting objective functions to optimise the energy consumption of constrained networks, contributing to the development of more sustainable IoT solutions.
