Material condition monitoring with multiple sensing modes

Methods are described for assessing material condition. These methods include the use of multiple source fields for interrogating and loading of a multicomponent test material. Source fields include electric, magnetic, thermal, and acoustic fields. The loading field preferentially changes the material properties of a component of the test material, which allows the properties of the component materials to be separated. Methods are also described for monitoring changes in material state using separate drive and sense electrodes with some of the electrodes positioned on a hidden or even embedded material surface. Statistical characterization of the material condition is performed with sensor arrays that provide multiple responses for the material condition during loading. The responses can be combined into a statistical population that permits tracking with respect to loading history. Methods are also described for measuring the stress in the material by independently estimating effective electrical properties, such as magnetic permeability or electrical conductivity, using layered models or predetermined spatial distributions with depth that are then correlated with the stress.

A system and method of using a multi-layered network model for analyzing the survivability of network services. The model is defined in terms of layers, connections, entities, physical processing elements, physical network elements, and physical infrastructure elements. Network services are modeled by sets of communicating entities at the application layer that are connected by connections at the underlying layers. The generality of the model constructs enable the construction of models of complex networks and services that can involve multiple layers of communication protocols, network elements, processing elements, and failover / backup mechanisms. The service survivability of a network is analyzed by projecting the failure of a set of physical elements onto the model and then determining the proportion of service affected at the application layer.

Method of networking systems reliability estimation

Interconnected networking systems is becoming a challenge in terms of dependability estimation as two main communication technologies co-exist in today's networks: switching and routing. These two technologies have two different and complementary levels of resilience. Switching is focused on sensitivity to delays and connectivity whereas routing is focused on traffic losses and traffic integrity. The main challenge in modeling these systems dependability is to aggregate the complexity and interactions from various layers of network functions and work with a viable model that reflects the resilience behavior from the service provider and the service user standpoints. The method uses a hierarchical approach based on the Markov Chains and RBD modeling techniques to build a multi-layered model of assuring a multi-services networking system meets its reliability targets dictated by a service level agreement. To cope with modeling complexity the multi-layered model is constructed so that each layer reflects the network resilience required level of details.
