introduction: the aim of this study was to evaluate the effects of morning and afternoon personality styles of the staff on an organization's psychological capital (optimism, resiliency, hope, and self-efficacy) based on fred luthans's model. we also assessed whether the relationship between personality type and psychological capital could affect the individual and organizational performance. m...

We investigate the problem of WS-BPEL processes resiliency in RBAC-WS-BPEL, an authorization model for WS-BPEL that supports the specification of authorizations for the execution of WS-BPEL process activities by roles and users and authorization constraints, such as separation and binding of duty. The goal of resiliency is to guarantee that even if some users becomes unavailable during the exec...

With the growing capability, expertise and intent of advanced cyber adversaries, it is no longer realistic to assume that one can successfully keep all adversaries out of a system infrastructure. Therefore, architecture and systems engineering must be based on the assumption that systems or components have been or can be compromised, and that missions and business functions must continue to ope...

New criteria of extended resiliency and extended immunity of vectorial Boolean functions, such as S-boxes for stream or block ciphers, were recently introduced. They are related to a divide-and-conquer approach to algebraic attacks by conditional or unconditional equations. Classical resiliency turns out to be a special case of extended resiliency and as such requires more conditions to be sati...

This paper provides a historical perspective and an overview of the pioneering work that Manfred Morari developed in the area of resiliency for chemical processes. Motivated by unique counter-intuitive examples, we present a review of the early mathematical formulations and solution methods developed by Grossmann and co-workers for quantifying Static Resiliency (Flexibility). We also give a bri...
