* This article is a reprint of a technical report [19] published in June 1974. The program listings from the appendices have been omitted, due to space constraints. The text has been retyped and the figures redrawn, but with no substantive changes. The references have been updated, as some were not yet in final form in 1974. ABSTRACT A security evaluation of Multics for potential use as a two-l...

Computer security professionals and researchers do not have a history of sharing and analyzing computer vulnerability information. Scientists and engineers from older or more established fields have long understood that publicizing, analyzing, and learning from other people's mistakes is essential to the stepwise refinement of complex systems. Computer scientists, however, have not followed sui...

In order to understand the seismic performance and mechanism of bottom frame seismic wall masonry structure (BFSWMS) and its vulnerability in empirical seismic damage, based on the statistical and numerical analysis of the field seismic damage observation data of 2178 Dujiangyan structures in the Wenchuan great earthquake urban of China on May 12, 2008, a non-linear function model between the s...

objective: we aimed to determine the relationship between self-efficacy and alexithymia with vulnerability to drug abuse among students. methods: the study method was descriptive and correlational. in this study, 483 male high-school students from salmas city, iran were selected by multi-stage cluster sampling method. all participants completed the toronto alexithymia scale, general self-effica...

The analysis of vulnerability in networks generally involves some questions about how the underlying graph is connected. One is naturally interested in studying the types of disruption in the network that maybe caused by failures of certain links or nodes. In terms of a graph, the concept of connectedness is used in dierent forms to study many of the measures of vulnerability. When certain vert...

Gaza coastal aquifer (GCA) is the major source of fresh water for the 1.5 million residents of Gaza Strip, Palestine. The aquifer is under deteriorating quality conditions mainly due to the excessive application of fertilizers. The intrinsic vulnerability of GCA to contamination was assessed using the well-known DRASTIC method. Detailed analysis of the intrinsic vulnerability map of GCA was car...

drastic is known as the most prototype models of groundwater vulnerability assessment. the drastic constitutes from seven schematic parameters consisting: depth to groundwater, recharge to aquifer, aquifer geology, and surface soil texture, impact of vadoze zone and hydraulic conductivity. in this study the models parameters were extracted by the main schematic maps of model. instead using the ...
