The present work is focusing on construction and analysis of 5 lunar models using space and ground observations. Firstly, it should be noted that the task of building a model of the lunar macro-figure relative to its center of mass and axes of inertia does not have a definitive solution yet. Within the present work the models of the lunar macro-figure are developed on the basis of space and ground observations. The methods of observation had implied binding of lunar objects to stars, i.e. celestial coordinate syst...

Research concerning magnetic diagnostics of the conveyor belt with steel cords was focused on its sections. In this paper authors are focusing on the extraction of the diagnostic parameters for the technical evaluation of the condition of the splice in belt conveyor. Data used for the analysis were acquired from the belt core testing using HRDS system. Parameters that are used in this paper take into account and can define its condition in the specific locations. Parameters were analysed and research shown influen...

Changes of damage to the belt core that are not controlled during the exploitation can lead to dangerous accumulation of the defects (strains) in the cross cross-section. It can lead to serious weakness and even rupture of the belt. Early detection of the mic rodamage of the covers and evaluation of the increase speed of the damage allows the user to plan maintenance more precisely. Furthermore, it allows more effective cost management when conveyor belt maintenance is scheduled. In this paper, geometric data o f ...
