In particular, a decomposition of entity model to the physical data model is presented. Understanding of significant differences between them makes it possible to build such structures of industrial databases that include special cases which occur in them. Different strategies for the transition from hierarchical entities model to targeted database tables are described. Additionally, an overview of problems associated with unary entities is outlined in this document.

https://doi.org/10.4467/2353737XCT.18.193.9681The paper presents the issue of boiling heat transfer enhancement with the use of different passive techniques, namely the application of wire mesh coatings, capillary porous layers, pin – fins and laser treatment. Enhanced boiling heat transfer has been described as well as the research data of the authors that deals with microstructural coatings. The conducted experimental tests confirm the possibility of increasing heat fluxes transferred at the same superheat value due to the use of heat transfer enhancing techniques.

https://doi.org/10.4467/2353737XCT.16.236.5985The paper presents models for designing of information systems for manufacturing. Chosen model of system implementation has a significant impact on the quality and performance of the target solution. Special focus is on the data model layer and the possibility of changing the standard three-tiered model of information systems through increased utilisation of resources of database server.
