  The purpose of this study is to propose the selection of installation sites based on publicly available data and sour cherry refrigeration container specifications, as well as to estimate the number of containers to be installed at possible sites. Today's escalating fuel supply and fuel price extremes make it particularly important to develop a sensible logistics sub-solution in the complex process of production, harvesting, storage, processing and sales. We undertook to develop a geospatial system that can be built and operated economically, its data sources can be updated occasionally or even at regular intervals, it is suitable for producing other outputs with additional descriptive or spatial data.

  High Pressure Die Casting (HPDC) is still the most productive metal-casting method of our time, however the more demanding are the industrial expectations, the more challenging it becomes to ensure the creation of the difficult cavity geometries and the thermal balance of the die-cast tool. New perspective is required, thus we can utilize high heat-conductivity tool steels and additive manufacturing technology.

  The height determination of control and detail points is essential during the process of planning and manufacturing in the practice of civil engineering. Planning maps are drawn for the former, while the intended plan is set out on the ground during manufacturing, and after the manufacturing the completed installation is mapped. Using the same reference system in all three steps, both horizontally and vertically, is recommended even though in some cases it is unavoidable to change from one reference level to another. Regardless of the fact that both refer to the mean sea level of the Baltic Sea, this can create difficulties, since the difference between the EOMA and Bendefy networks used in Hungary shows varying values depending on the geographical location. The aim of the analysis is to determine a constant difference regarding the analysed settlements based on the common points of the networks.
