Blockchain technology has the potential to address these challenges, but it is still underdeveloped and unfamiliar to many companies. This thesis aims to assess the state of existing supply chain management systems and create a prototype for a tracking and tracing system that provides complete visibility and transparency across the food supply chain using a centralised database and QR codes. The study will help us better understand the possibilities of centralised tracking and tracing systems in supply chain management and provide businesses with useful advice on how to make their supply chains more secure and transparent. Read the full article....

The increasing development of digital technologies in the field of engineering has led to the invention of various methods for digitisation processes. The use of Building Information Model (BIM) already extends to the application for infrastructure objects. Therefore, the need for the practical implementation of a BIM for each type of the specific objects is sufficient. The work aims to develop an optimal technique for the application of BIM for built bridges. Read the whole article...

This paper proposes a method for digitising gyro vibrations for automating gyro measurements using a linear sensor camera and programming code. It also analyses the history of gyro design from invention to modern automated devices. The main objective of this work is to develop a technology for automatic determination of the position of a light source and further calculation of the necessary data with the possibility of application in a gyroscope. The accuracy of the determination of the main values should be higher than in manual methods. Read the whole article...

The trends in optical three-dimensional measurements today are high accuracy, low price, real-time processing and portability of the devices. Combined with the improvement of old methods and the emergence of new ones, there is a strong need to compare them to find the best solution for a specific task. The master thesis covers implementation, recommendations and optimal settings of current optical three-dimensional measurement methods such as laser tracker measurements and laser, photo-based and handheld scanning for geometric inspection of production parts in shipbuilding.
