This thesis presents a systematic investigation into the electromagnetic field (EMF) radiation characteristics of high-voltage overhead transmission lines in the Vilnius region of Lithuania. The study is motivated by growing public and scientific concern regarding the potential health implications of prolonged human exposure to extremely low frequency (ELF) electromagnetic radiation emitted by electrical power infrastructure operating at 50 Hz, particularly as such infrastructure increasingly passes through densely populated areas. The research was conducted in two principal phases. The first involved the development of a custom two-dimensional Finite Element Method (FEM) computational model in MATLAB, used to simulate the spatial distribution of electric and magnetic fields surrounding the Kino Studija鈥揤ilnia 110 kV double-circuit overhead transmission line. The second phase consisted of physical field measurements recorded on-site using a calibrated NFA 1000 broadband field analyser at a standardised height of 1.5 metres above ground level, taken both directly beneath the line and at varying lateral distances from the tower centreline. Simulation and measurement results demonstrated strong agreement within a 1.16% margin, with the MATLAB model predicting a peak electric field of 1891.8 V/m against a measured value of 1914 V/m. Magnetic flux density peaked at 0.7171 碌T directly beneath the tower and decayed steadily with increasing lateral distance. All results were benchmarked against the ICNIRP guidelines, IEEE Std C95.1鈩�-2019, and the Lithuanian national hygiene norm HN 104:2011. While the line complied fully with the international standards, which specify a 5000 V/m electric field limit, the stricter Lithuanian outdoor threshold of 1000 V/m was exceeded within approximately 35 metres of the tower centre, with full compliance only achieved beyond 40 metres. Magnetic flux density remained well within all applicable limits at every measurement point. The study concludes that the line adheres to international regulatory frameworks but presents localised non-compl

The master鈥檚 thesis examines the application of object detection technologies in barrier-based car parking systems. The relevance of the thesis is determined by the need to ensure reliable detection of vehicles and other objects, as well as the safe operation of barriers under real operating conditions. The thesis analyses inductive loop, microwave radar, ultrasonic, and infrared sensors, including their operating principles and potential applications. During the experimental study, activation data from different sensors were recorded in real parking systems. Their response time, reliability, and number of false activations were evaluated. Different sensor combinations were also developed and tested in order to determine whether combining several technologies can compensate for the limitations of individual sensors. The results showed that the most reliable performance is achieved by combining an inductive loop sensor with microwave radar. The thesis consists of the following sections: introduction, literature review, methodology, experimental study, conclusions, and a list of bibliographic references. The thesis has a length of 51 pages excluding appendices, including 27 figures, 5 tables, and 54 bibliographic references.
