Withstanding Pressure in Any Shape

Withstanding the pressure of the profession.

Nurses often practice in chaotic, demanding work environments. Understanding the negative impact these environments have on nurses and patients is paramount to halting this epidemic. Researchers' decade-old call for administrators and managers to correct this occupational hazard is ineffective in decreasing the effects of prolonged work-related stress on nurses. Staff development educators' mod...

Analysis of Axisymmetric Extrusion Process through Dies of any Shape with General Shear Boundaries

In this paper, a generalized expression for the flow field in axisymmetric extrusion process is suggested to be valid for any dies and the boundary shapes of the plastic deformation zone. The general power terms are derived and the extrusion force is calculated by applying upper bound technique for a streamlined die shape and exponential functions for shear boundaries. It is shown that assuming...

Phalanx: Withstanding Multimillion-Node Botnets

Large-scale distributed denial of service (DoS) attacks are an unfortunate everyday reality on the Internet. They are simple to execute and with the growing prevalence and size of botnets more effective than ever. Although much progress has been made in developing techniques to address DoS attacks, no existing solution is unilaterally deployable, works with the Internet model of open access and...
