This work uses a custom-built digital bagpipe chanter interface to assist in the process of learning the Great Highland Bagpipe (GHB). In this paper, a new algorithm is presented for the automatic recognition and evaluation of the various ornamentation techniques that are a central aspect of traditional Highland bagpipe music. The algorithm is evaluated alongside a previously published approach...

Species spanning the animal kingdom have evolved extravagant and costly ornaments to attract mating partners. Zahavi's handicap principle offers an elegant explanation for this: ornaments signal individual quality, and must be costly to ensure honest signalling, making mate selection more efficient. Here, we incorporate the assumptions of the handicap principle into a mathematical model and sho...

a bstr act I present and evaluate various criticisms against the view that architecture and architectural value are to be understood solely in terms of internal space. I conclude that the architectural value of a building should not be limited to its internal spatial effects because the value of other elements, such as (non­spatial) function, materials, ornamentation, and so on cannot all be re...

Signal honesty is theorized to be maintained by condition-dependent trait expression. However, the mechanisms mediating the condition dependence of sexually selected traits are often unknown. New work suggests that elevated glucocorticoid levels during physiological stress may play a role in maintaining signal honesty. Here, we experimentally examine the effect of both chronic and acute stress ...

The expression in females of ornaments thought to be the target of sexual selection in males is a long-standing puzzle. Two main hypotheses are proposed to account for the existence of conspicuous ornaments in both sexes (mutual ornamentation): genetic correlation between the sexes and sexual selection on females as well as males. We examined the pattern of ornament gains and losses in 240 spec...

northern Nāgara and the southern Drāvid. a. Though often regarded simply as an ornament, as implied in such phrases as ‘the niche pediment is adorned with caitya arch motifs’, the gavāks. a is not only ubiquitous, but also integral to the Nāgara and the Drāvid. a, having been a basic element in the range of timber structures which provided the initial imagery for both of the two broad tradition...

Ornament displays seen in animals convey information about genetic quality, developmental history and current disease state to both prospective sexual partners and potential rivals. In this context, showing of teeth through smiles etc is a characteristic feature of human social interaction. Tooth development is influenced by genetic and environmental factors. Adult teeth record environmental an...

Published by Elsevie ND license (http://creativecommons.org/licenses/by-n Theoretical support exists for an exaggerated male structure to serve as both a weapon for intrasexual competition and as an ornament to signal quality and promote female choice. However, there is little, if any, evidence to support this theory ...
