An infrastructure impact assessment process relies on the analysis of multiple types models, performance individual networks and interdependencies between networks. Several models are developed for their specific purposes there is a need to link these natural hazard impacts distributed infrastructures deliver desired outcomes network functionality disruption levels that suitable assess socio-ec...

The low earth orbit (LEO) constellation network has become a promising approach to provide global communication services, due its advantages in wide coverage, transmission delay, and convenient networking. However, the instability of intersatellite laser terminal high relative speed between adjacent satellites cause frequent topology changing problems for data routing. In this paper, disruption...

Abstract Many core marketing concepts (e.g., markets, relationships, customer experience, brand meaning, value) concern phenomena that are difficult to understand using linear and dyadic approaches, because they emergent. That is, arise, often unpredictably, from interactions within complex dynamic contexts. This paper contributes the discipline through an explication of concept emergence as it...

Spectrum sensing vulnerabilities in cognitive radio networks can significantly degrade performance. Most disruption attacks the current literature involve spoofing of free bands used for by making them appear busy. In this study, we proposed a different approach disruptions. We examined optimal strategy an intelligent adversary with given power to flip busy and make free. The mechanism was esta...

background: angiotensin ii (ang ii) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. this study evaluated the role of central ang ii by using candesartan, as an at1 receptor blocker, in the brain edema formation and blood-brain barrier (bbb) disruption caused by ischemia/reperfusion (i/r) injuries in rat. methods...

background: nitric oxide synthase (nos) activity is increased during hypertension and cerebral ischemia. nos inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (bbb) disruption and cerebral edema formation during stroke in acute hypertension. here, we investigated the role of nos inhibition in progression of edema formation and bbb d...

in the last two decades due to globalization of supply chain, enormous changes occurred in chains. leaders in this field, always facing new risks and disorders that should prepare themselves to deal with them. in the recent years, sanctions as one of the most serious risks have damaged the supply chains. however, in the research related to global supply chains, modeling of disruption has been n...

major pancreatic injury following blunt abdominal trauma by itself is a relatively rare occurrence, and in vast majority of cases (95%) it is associated with injury to adjacent major vessels and organs; thus making isolated major pancreatic injury even rarer. while most pancreatic injuries are managed by simple measures like debridement and drainage, complex proximal injury poses surgical chall...

This paper presents an application of Continuum (i.e. Lagrangian) and Finite Element Techniques to flexible manipulator arms for derivation of the corresponding Dynamic Equations of Motion. Specifically a one-link flexible arm is considered for detailed analysis, and the results are extended for the case of a two - link flexible manipulator. Numerical examples are given for the case of both one...
