DIPHTHERIA FROM FAULTY DRAINAGE.

Recovering from Faulty Device Drivers

Several studies (see Swift et. al.’s study of Windows XP in SOSP 2003 and Chou et. al’s study of Linux in SOSP 2001) have attributed a large fraction of operating system failures to device driver flaws. Not only can driver errors cause kernel instability, but these errors can also be exploited for privilege escalation and access to kernel data structures. A search on securityfocus.com shows vul...

Drainage basin delineation from vector drainage networks

An automated process for the delineation of drainage basins, using as input only the vector based drainage network, is described which provides an alternative to DEM based methods. The procedure involves an approximation of the line Voronoi diagram for the network using a constrained Delaunay triangulation of the network's Planar Straight Line Graph. The constrained triangulation, which include...

Diphtheria

Gentlemen,?I have occasionally heard a man, about to read a paper upon some subject, commence by expressing his sense of his unfitness for the task he has undertaken. I have, I must confess, looked upon this appeal, ad misericordiam, with much suspicion, believing the writer, did he not in his own heart believe himself particularly well-fitted for the work, would not have undertaken it.
