The drainage of low-sloped roof systems involves multiple design professionals, and often each has a different opinion as to their design responsibility. Roofing issues have been identified as being a number one source of litigation, and rain-induced roof collapses continue to occur with alarming frequency. With the backdrop of several rain-induced roof collapses, this paper illustrates the com...

We present an analysis of AAVSO visual observations of the Mira variable R Cen from 1918 to 2000. The period of the dominant mode has been steadily decreasing from 550 days at JD 2,434,000 (1951) to its present value of 505–510 days. In the same interval, the pulsational amplitude has decreased by 3 mag, from 5.5–11.8 V to 6.3–9.1 V. We suggest that both are caused by a He-shell flash, as the p...

This paper presents a data-driven method for automatic building reconstruction from raw airborne laser scanner data. The method utilises a TIN-structure that is calculated into the point cloud. The parameters of every TIN-mesh are mapped into a 3D trianglemesh parameter space, which is then analysed using a cluster analysis technique. By analysing the clusters, significant roof planes are deriv...

INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...
