The NDT methods currently used in aviation MRO are predominantly labour-intensive and time-consuming processes performed by human operators throughout the lifespan of an aircraft. These techniques are time-consuming, require perpetual training and are highly dependent on the operator's skills. Thus, …

Post-earthquake structural damage shows that out-of-plane wall collapse is one of the most prevalent failure mechanisms in unreinforced masonry (URM) buildings. This issue is particularly critical in Groningen, a province located in the northern part of the Netherlands, where low-intensity ground shaking …

In this paper we describe one aspect of nature-based flood protection by foreshores in hybrid flood defences and discuss how foreshore ecosystem restoration can contribute to flood protection. Flood protection consists of flood prevention, by grey, green or hybrid defences, and flood impact reduction, …

''Heritage buildings are often subjected to loading conditions that they were not exposed to in their earlier life span. Induced earthquakes in non-seismic regions caused by energy exploitation activities, or strains in the ground that are caused by the climate changes, are new phenomena that alter the …

Dit onderzoek richt zich op een urgente versterkingsmaatregel na aardbevingen om de seismische restcapaciteit van door aardbevingen beschadigde gewapend betonnen wandconstructies met koppelliggers te verbeteren. Het onderzoek bestaat uit een serie testen op halfschaal prototype koppelbalken met verschillende …

Abstract: Climate change is related with weather extremes, which may cause damages to infrastructure used by freight transport services. Heavy rainfall may lead to flooding and damage to railway lines, roads and inland waterways. Extreme drought may lead to extremely low water levels, which prevent …

The design and mission requirements of aero vehicles, which vary on a day-to-day basis, have become major study concerns in the burgeoning aviation sector. In addition to the design and mission criteria that must be met in an aero vehicle design, the designers' primary goals are to construct original, …

5% to 10% of all cancers are linked to gene mutations inherited from parents. The most common gene related to hereditary cancer is the p53 gene. It is a crucial tumor suppressor. However, the mutated gene is commonly inherited from one generation to another one. The functions of p53 resume to the activation …

In this study, aviation, energy, exergy, environmental, exergoeconomic, and exergoenvironmental analyses are performed on a CFM56-3 series high by-pass turbofan engine fueled with Jet-A1 fuel. Specific fuel consumption and specific thrust of the engine are found to be 0.01098 kg/kN.s and 0.3178 kN/kg/s, …

The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …
