Catastrophic disruptions of large, interconnected infrastructure systems are often due to cascading failure. For example, large blackouts of electric power systems are typically caused by cascading failure of heavily loaded system components. We introduce the CASCADE model of cascading failure of a system with many identical components randomly loaded. An initial disturbance causes some compone...

INTRODUCTION: Supply chains face various disruptions from human-made to natural disasters preventing proper flow of materials and products. This problem is more important in the healthcare supply chains, especially the blood supply chains, in which human lives are at risk. Making the supply chains resilient, recently addressed by managers and researchers, can be a good way to tackle them. This ...

This article uses grounded theory methods to research the history of a therapeutic community and highlights the possibilities of ‘being able to learn’ as an aim for history of medicine research. For this case study, processes of research and learning allow consideration of the ‘dilemma of paternalism’ and the interaction between history, policy and practice. How can students enter into discours...

Critical Infrastructures’ disruptions may result in crises of unacceptable outcomes in modern societies. Thus, it is important to develop models that allow describing CIs’ disruptions and their propagation characteristics. CI disruptions depend on both the type of the threat and on the nature of the CIs’ mutual dependencies. A model describing the cascade of disruptions should, then, be able to...

We consider the single machine scheduling problem with dynamic job arrival and total weighted tardiness and makespan as objective functions. The machine is subject to disruptions related to late raw material arrival and machine breakdowns. We propose a proactive-reactive approach to deal with possible perturbations. In the proactive phase, instead of providing only one schedule to the decision ...

Convective weather is responsible for large delays and widespread disruptions in the U.S. National Airspace System (NAS), especially during summer months when travel demand is high. This has been the motivation for Air Traffic Flow Management (ATFM) algorithms that optimize flight routes in the presence of reduced airspace and airport capacities. These models assume either the availability of r...

this article analyses the effects of post-zionism in israeli ,society and state. by using the discoursive analysis in social theory, the author argues that discourses such as post-zionism are the results of socio-political and economic conditions (processes), but their evolution is basically the result of the mental and value activities of their proponent, rather than the socio-political proces...

We consider a homogeneous tree endowed with nondoubling flow measure $\mu$ of exponential growth and probabilistic Laplacian $\mathcal{L}$ self-adjoint respect to $\mu$. prove that the maximal characterization in terms heat Poisson semigroup Riesz transform atomic Hardy space introduced previous work fail.

We present a veriied symbolic deenite integral table look-up: a system which matches a query, comprising a deenite integral with parameters and side conditions, against an entry in a veriied table and uses a call to a library of facts about the reals in the theorem prover PVS to aid in the transformation of the table entry into an answer. Our system is able to obtain correct answers in cases wh...
