Reliability-based analysis of recycled aggregate concrete under carbonation [PDF]

open access: yes, 2018
Durability represents a crucial issue for evaluating safety and serviceability of reinforced concrete structures. Many studies have already focused on carbonation-induced corrosion of natural aggregate concrete (NAC) structures, leading to several ...

Security versus Reliability Analysis of Opportunistic Relaying

open access: yes, 2013
Physical-layer security is emerging as a promising paradigm of securing wireless communications against eavesdropping between legitimate users, when the main link spanning from source to destination has better propagation conditions than the wiretap link

Computation-Based Reliability Analysis [PDF]

open access: yesIEEE Transactions on Computers, 1976
A reliability analysis method for computing systems is considered in which the underlying criteria for "success" are based on the computations the system must perform in the use environment. Beginning with a general model of a "computer with faults," intermediate concepts of a "tolerance relation" and an "environment space" are introduced which account

Catastrophic risks and insurance [PDF]

open access: yesMegatrend Revija, 2016
Catastrophic events do not know borders; they threat the local community, but also the whole continent. Catastrophic risk represents the individual risk which endangers a relatively large number of people or property, at the same time posing a threat to ...
