Network Management is an indispensable part of any successful telecommunications network. It consists of real time surveillance and control of the network. This paper describes an effective dynamic control loop to ensure a stable and good Grade of Service in network under focussed overload. Aspects which have qualitative and quantitative influences on the declination of the network goodness wil...

Actual aerospace and defense technologies present multiple limitations that need to be overcome in order to evolve to less contaminating and more efficient aircraft solutions. Contactless technologies come with essential advantages such as the absence of wear and friction. This work describes the design, prototype, and performance test according to RTCA-DO-160 of an aeronautical magnetic torque...

PURPOSE: The deterioration of elements of steel hydraulic structures (SHS) on our nation’s lock system is caused by combined effects of several complex phenomena: corrosion, cracking and fatigue, impact, and overloads. This Coastal and Hydraulics Engineering Technical Note presents examples of deterioration and a method for predicting future deterioration based on current conditions. In a compa...

In Perry and Whitt (2009) we considered two networked service systems, each having its own customers and designated service pool with many agents, where all agents are able to serve the other customers, although they may do so inefficiently. Usually the agents should serve only their own customers, but we want an automatic control that activates serving some of the other customers when an unexp...

The prevalent use of the Session Initiation Protocol (SIP) in Next Generation Networks necessitates that SIP networks provide adequate control mechanisms to maintain transaction throughput by preventing congestion collapse during traffic overloads. A loss-based solution to remedy known vulnerabilities of the SIP 503 (Service Unavailable) overload control mechanism has already been proposed. Usi...
