Strongly nonlinear multi-degree of freedom systems: Experimental analysis and model identification

Lightweight structures, once ubiquitous in specific sectors such as aeronautics and space sectors, in recent years, have increasingly attracted the attention of industries that, historically, have not been particularly concerned with structural weight. Ample examples are provided by the civil and automotive industry, in which the paradigm...

Experimental investigation of wave attenuation by mangrove forests with submerged canopies

Mangroves can function as a ‘bio-shield’ to protect coastal communities from harsh environments because of their strong ability to attenuate wave energy. However, as mangroves are usually oversimplified as rigid cylinders in antecedent studies, the effects of complex mangrove morphology on wave attenuation have not been well researched....

Design and experimental analysis of an active and passive camber morphing system for rotor blades

Modern helicopters are equipped with rotor blades with exposed linkages, swashplates, and mechanical components. While such rotor blades have proved to be highly reliable, they are the leading cause to generate noise and vibration. In addition, the drag due to exposed linkages and hinges affects the helicopter performance. To overcome these...

Equalizing bias in eliciting attribute weights in multiattribute decision-making: experimental research

One of the most important steps in formulating and solving a multiattribute decision-making (MADM) problem is weighting the attributes. Most existing weighting methods are based on judgments by experts/decision-makers, which are prone to several cognitive biases, making it necessary to examine these biases in MADM weighting methods and...
