Abstract The question of whether there exists an approximation procedure to compute the resonances any Helmholtz resonator, regardless its particular shape, is addressed. A positive answer given, and it shown that all one has assume resonator chamber bounded boundary $${{\mathcal {C}}}^2$$ C </mml:m...

The current information marketplace for tourists is dominated by for-profit purveyors of information. Potential visitors must rely on experts-for-hire or search engine results in order to learn about a desired destination. In this paper, we introduce The Madeira Touch, a multimodal display installation rooted in the unique characteristics of Madeira, which allows users to explore the island by ...

Non-native ascidians are important members of the fouling community associated with artificial substrata and man-made structures. Being efficient fouling species, they are easily spread by human-mediated transports (e.g., with aquaculture trade and maritime transports). This is exemplified by the ascidian Asterocarpa humilis which displays a wide distribution in the Southern Hemisphere and has ...

The main objective of this study is to see what extent it possible recover a material from road waste: the case seashell aggregate. Public works produce 100 millions tonnes surplus and construction waste every year. Among million tons, 95% inert non-polluting waste. And faced with ever-increasing demand for materials scarcity satisfying specifications, urgent initiate programs on possibility us...

Pretense has been implicated as playing a role in the development of many cognitive and social skills. Despite the importance and ubiquity of this phenomena, few computational models of pretense exist. We propose a model of pretense via analogical abduction. We suggest that pretense occurs via structural alignment. Where a mismatch occurs (i.e. something in the pretend scenario is not the same ...

A long metal thread breaks more easily than a short one—an observation Leonardo da Vinci made in the 15th century. It all comes down to simple statistics: the larger an object, the more likely it is to contain a region that breaks when subject to stress. The fracture properties of brittle materials also depend on the disorder in their underlying structure: a homogeneous material like glass brea...
