Abstract: The current paper aims at the assessment of the effectiveness of a popular transient-based technique—inverse transient analysis (ITA)—for leak detection in water pipe systems using physical data. Data were collected from ...

Abstract: The main goal of this work is to study the role of energy storage in the context of the Portuguese power system by the year 2030. Portugal is one of the countries in the world with more installed energy storage capacity, ...

Abstract: Fluid-induced instability in rotating systems due to the presence of hydrodynamic journal bearings consists of an undesirable phenomenon with a considerable destructive potential. Surface texturing of journal bearings is ...

Abstract: It is essential for electronics reliability to develop effective methodologies to detect hidden solder joint defects. Active infrared thermography is an alternative to Xray detection methodologies. The limits of active ...

Abstract: This work presents an analytical model for the structural analysis of flexible risers subjected to combined loads of bending, twisting and tension, as well as internal and external pressures ...

Abstract: A numerical model for the ultimate analysis of externally prestressed concrete bridges has been developed. The proposed model can analyze simply supported or continuous, monolithic or segmental bridges, with external ...

Abstract: Risers anchored in a floating system and excited by a moderate sea state are often subjected to dynamic compression near the touchdown point, since the static tension in this region is usually ...
