Objectives: This article reports the first science mapping analysis of the social work field, which shows its conceptual structure and scientific evolution. Methods: Science Mapping Analysis Software Tool, a bibliometric science mapping tool based on co-word analysis and h-index, is applied using a sample of 18,794 research articles published from 1930 to(More)
Water distribution networks are not randomly constituted systems. On the contrary, their designs are closely related to their hydraulic performance. Recognizing the sundry and relative importance of the different pipes in a water distribution network may help in assessing their impact on the hydraulic performance of the network. This information, in turn,(More)
We propose a methodological tool for examining the layout and revealing the concealed characteristics of urban water supply systems (WSS). For this purpose, we use underground images obtained with ground penetrating radar (GPR) as a method that does not alter the system conditions and environmental characteristics (non-destructive methods). The study(More)
Many critical infrastructures consist of networks with complex structure, since they have highly interdependent elements and nontrivial designs with a degree of complexity that depends on the settings and level of interaction between these elements. The theory of complex networks employs techniques borrowed from graph theory to classify different types of(More)
