Feasibility study of a non-contact, non-destructive testing method to assess the structural integrity of synthetic mooring ropes

Governments are looking more and more to invest in renewable energy sources due to the energy transition that is currently taking place. One of the many renewable energy sources is wind energy which is increasingly positioned at sea. Wind turbines in deep parts of the ocean can be placed on floating structures which are often moored to the sea...

In-situ Non-destructive Stiffness Assessment of FRC Materials

Fiber Reinforced Composite (FRC) materials are gaining great popularity in marine structures because of their excellent strength-to-weight ratio, low density, and provided freedom in the design process. However, the use of FRC materials comes along with relatively large uncertainties in material properties and structural integrity after...

Transceiver design for reciprocal operation of ultrasonic flow measurement systems

In transit-time ultrasonic flow measurement systems, the system's ability to operate reciprocally in the absence of flow is a highly desirable property. If the reciprocity is lacking in the system, any time delay that appears between the upstream and downstream signals at zero-flow conditions will result in false flow measurement. This...

Assessment of Using Low-frequency Ultrasound Device for Domestic Drinking Water Disinfection

Microorganisms may cause problems in drinking water distribution system (DWDS). It is hard to control and always forms the biofilm, which can result in the deterioration of drinking water quality. At household’s tap, due to the favorable conditions, which incurs an easier formation of biofilm. Therefore, the idea of secondary disinfection at...

Performance of structural glass at elevated temperatures: A research into the Young’s modulus of glass and the effect of coatings on laminated glass panels at elevated temperatures

Nowadays glass is more commonly applied as structural element, either as a replacement for, or in collaboration with conventional building materials such as steel, aluminium, timber and concrete. Key arguments to opt for glass in structural design are sustainability, aesthetics and transparency. As for all structural elements, glass elements are...
