Executable content poses a threat of unauthorized access because it contains program code running on the user’s machine. Protecting against executable content is difficult because of the inevitable flaws in the implementation of protection mechanisms. This paper introduces a hierarchical protection model to tolerate flaws in protection mechanisms. This model improves both the granularity and th...

background: studies show that about 90% of accidents occur because of unsafe behavior and human errors. even if workers do not have the right knowledge, attitude and behavior toward safety measures in a safe workplace, all efforts for an accident-free workplace will be in vain. this study aims to determine the level of knowledge, attitude and behavior of workers toward occupational health and s...

pullback test has no scrupulous theoretical establishment. it is based on the hypothesis that the response ofthe structure can be related to the response of an equivalent single degree-of-freedom (sdof) system. this implies thatthe response is controlled by a single mode. in fact, the steel frame of each safe room, which is introduced within theunreinforced masonry buildings for protecting the ...

In this paper the effect of faults in the elements and parts of discrete event systems is investigated. In the occurrence of faults, some states of the system must be changed and some of them must be forbidden. For this goal, different states of these elements are examined and a model for fail-safe behavior of each state is introduced. Replacing new models of the target elements in the prelimin...

In this article we show how to implement merger simulation in Stata after estimating an aggregate nested logit demand system with a linear regression model. We also show how to implement merger simulation when the demand parameters are not estimated, but instead calibrated to be consistent with outside information on average price elasticities and pro…t margins.

We chart the ways in which closure properties of consequence relations for uncertain inference take on different forms according to whether the relations are generated in a quantitative or a qualitative manner. Among the main themes are: the identification of watershed conditions between probabilistically and qualitatively sound rules; failsafe and classicality transforms of qualitatively sound...
