A study on some system safety models
نویسندگان
چکیده
In this paper two system safety models are built based on some practical situations. The system state can be distinguished into three states: working, fail-safe and fail-dangerous.The probabilities that the system are in working state, fail-safe state and fail-dangerous state, respectively, are derived. Also the mean times for the system working, fail-safe and fail-dangerous, are given. Finally some numerical examples are presented to illustrate the results obtained in this paper.

Vertical Contraction Joint Models for Nonlinear Dynamic Analysis of Concrete Arch Dam
Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

متن کاملEstimation Model of Two-Lane Rural Roads Safety Index According to Characteristics of the Road and Drivers’ Behavior
Vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. A large number of the vehicle crashes occur on rural roads. Accidents become more noteworthy in two-lane roads due to going and coming traffic. Therefore, prediction of crashes and their causes are considerably important to reduce the number and severity of the accidents. The safety index is...

In this review, we discuss the use of a variety of 3-D models (particularly 3-D skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-D culturing conditions (monolayers). We review the characteristics of existing 3-D models and aim to point out the substantial advantages 3-D cultures provide for modern radiobiology. In particula...
