igher Education P 0.1016/j.foar.2012 [email protected] responsibility of Abstract The present paper is part of a research that is developed within the sustainable building design through the revisiting of the traditional construction materials. The results obtained show that the natural stone, enhanced by technological innovations, are often capable of providing excellent performance. Based on th...

Abstract An ultrasonic technique has been experimented for non destructive testing of building structures. The Through Transmission Technique has been applied, processing the wave incident on a grid of detecting probes after it has been transmitted through a trachite stone masonry with an inside cavity. Several parameters associated with acoustic waves propagating through the structure have bee...

The new paradigm of “knowledge construction using experiential based and collaborative learning approaches” is an outstanding opportunity for interdisciplinary research. This document is an attempt to introduce and exemplify as much as possible using the lexicon of “social sciences”, considerations and tools belonging to “artificial intelligence”. In the paper we first draw a conceptual framewo...

the municipality of tehran is intending to construct a permanent international flower exhibition. the activities for construction began in the year 2006. the exhibition has three distinct areas namely “northern area”,”southern area” and “central area”. in northern and southern area the flowers are supposed to be preserved and in central area, they will be sold out. in the present st...

This paper presents the petrographic and textural characterization of some ornamental limestones widely used in UNESCO World Heritage Sites northeastern Italy, assessment main decay factors present environment where they are employed. Eleven carbonate building materials have been here considered, all commonly built Italy: two different varieties Vicenza Stone (Nanto Costozza), Verona (Red Brown...

hairball in a urethral diverticulum has rarely been reported. these hairballs are usually formed in the diverticulum coated with a hair bearing epithelium and can lead to urinary obstruction or infection. using laser is a safe way to ablate such stones.

Gabriel Taubin Brown University Holly Rushmeier, who’s served as associate editor in chief (AEIC) for special issues since 2007, has recently been appointed co-editor in chief of Eurographics’ Computer Graphics Forum, effective May 2010. Owing to her increased responsibilities and numerous other commitments, Holly has decided she’ll be unable to continue serving effectively in her current CG&A ...

In this paper we argue that the category of Stone spaces forms an interesting base category for coalgebras, in particular, if one considers the Vietoris functor as an analogue to the power set functor on the category of sets. We prove that the so-called descriptive general frames, which play a fundamental role in the semantics of modal logics, can be seen as Stone coalgebras in a natural way. T...

This paper presents a practical approach for designing, erecting, and testing stone columns using the vibro-replacement method to improve soil bearing capacity under shallow foundations (isolated and raft foundations) for any typical building under small or medium loading conditions. Usually, the vibroreplacement method is used in soils with cohesive layers of mixed deposits, loose sand, or bot...
