Around 45% of natural hazards reported worldwide are related to floods, and current indications show that exposure floods inherent losses will keep escalating. Historic centres particularly vulnerable in this context due the structural material characteristics buildings because they embrace social cultural values must be safeguarded. This article aims contribute research area by presenting disc...

Surf breaks and surfing areas exemplify the human dimensions of coastal ecosystems—places connecting people nature from which history, culture, tradition, economic activity, even political conflict emerge. We employed a signature policy instrument American historic preservation, National Register Historic Places (National Register), as context to both evaluate ultimately recognize these connect...

‎let $x$ be a real normed  space, then  $c(subseteq x)$  is  functionally  convex  (briefly, $f$-convex), if  $t(c)subseteq bbb r $ is  convex for all bounded linear transformations $tin b(x,r)$; and $k(subseteq x)$  is  functionally   closed (briefly, $f$-closed), if  $t(k)subseteq bbb r $ is  closed  for all bounded linear transformations $tin b(x,r)$. we improve the    krein-milman theorem  ...

in this article, we have shown, for the add-point monad t, thepartial morphism category set*is isomorphic to the kleisli category sett. alsowe have proved that the category, sett, of t-algebras is isomorphic to thecategory set of pointed sets. finally we have established commutative squaresinvolving these categories.

The character of a brass musical instrument is primarily dependent on its bore profile. Many historic brass instruments are so constructed that substantial parts of the air column are inaccessible to direct measurement. This paper discusses the factors involved and reports recent advances in the use of pulse reflectometry for bore reconstruction, in particular compensation for losses and allowa...

Augmented reality is very well suited to convey information in the context of historic sites, as it is possible to integrate such systems in an unobtrusive manner. In this paper we present Corona, an audio augmented reality experience deployed in the historic town hall of Aachen/Germany. We describe the auralization process and the technology used and give an outlook on interesting research que...
