This research, carried out by a bioengineering-surgical team from three Polish universities, includes bioengineering design, rapid prototyping, manufacturing in selective laser melting, functionalization, surface modification, numerical studies, experimental in vitro studies, and pilot surgical experiments in an animal model. Features: Presents the prototype of the multi-spiked connecting scaffold for a new generation of resurfacing endoprostheses of the knee and the hip, Explains this prototype scaffold as the first worldwide design of the biomimetic fixation of components of diarthrodial joints resurfacing endoprosthesis Insights into the entire process of bioengineering design and research on this novel way of resurfacing endoprostheses fixation, Reviews main results of the scaffold prototyping and SLM manufacturing, structural and osteoconductive functionalization, and surface modification, Reports experimental and numerical investigations of mechanical behavior of the scaffold-bone system, cell culture studies, and pilot surgical experiments in animal models. This book is aimed at professionals and graduate students in biomedical engineering, biomaterials engineering, and bone & joint surgery.

These systems include modules dedicated to particular branches of municipal economy, such as urban transport, heating systems, energy systems, telecommunications, and finally water and sewage management. In turn, with regard to the latter branch, IT systems supporting the management of water supply and sewage networks and sewage treatment plants are being developed. This paper deals with the system concerning the urban water supply network, and in particular, with the subsystem for detecting and locating leakages on the water supply network, including so-called hidden leakages. These leaks cause the greatest water losses in networks, especially in old ones, with a very diverse age and material structure. In the proposed concept of the subsystem consisting of a GIS (Geographical Information System), SCADA (Supervisory Control and Data Acquisition) system and hydraulic model of the water supply network, an algorithm of leak detection and location based on the neural networks’ MLP (multi-layer perceptron) and Kohonen was developed. The algorithm has been tested on the hydraulic models of several municipal water supply networks. Wed, 01 Jan 2020 00:00:00 GMT https://repozytorium.ukw.edu.pl///handle/item/7993 2020-01-01T00:00:00Z
