Microseismic monitoring in petroleum settings provides insights into induced and naturally occurring stress changes. Such data are commonly acquired using an array of sensors in a borehole, providing measures of arrival times and polarizations. Events are located using 1D velocity models, P‐ and S‐wave arrival times and the azimuths of P‐wave particle motions. However in the case of all the sensors...
Adding autonomic capabilities to network management systems provides great promise in delivering high QoS while lowering operation and maintenance cost. In this paper, we present a model-based approach to adding autonomic capabilities to a fault management system for cellular networks. We propose the use of modeling techniques to specify software failures and their dispositions at the model level...
Autonomic and other system management technologies must ascertain the current state of a managed system comprising interconnected but at times independent and diverse managed entities. When an autonomic manager is introduced into a running system, state bootstrapping is required. One challenge involved in state bootstrapping is balancing the need to have current and detailed state information against...
Adding self-healing capabilities to network management systems holds great promise for delivering important goals, such as QoS, while simultaneously lowering capital expenditure, operation cost, and maintenance cost. In this paper, we present a model-based approach to add self-healing capabilities to a fault management system for cellular networks. We propose a generic modeling framework to categorize...
In this paper, we propose an adaptive framework for adding the most desired aspects of autonomic capabilities into the critical components of a network fault management system. The aspects deemed as the most desirable are those that have a significant impact on system dependability, which include self-monitoring, self-healing, self-adjusting, and self-configuring. Self-monitoring oversees the environmental...
The purpose of autonomic networking is to manage the business and technical complexity of networked components and systems. However, the lack of a common lingua franca makes it impossible to use vendor-specific network management data to ascertain the state of the network at any given time. Furthermore, the tools used to analyze management data, which include information and data models, ontologies,...
Motorola's seamless mobility solution is one specific example of generic next generation services. Such services use applications that provide a world of simple, intuitive, and uninterrupted access to information based on the user's context. Fundamental to this concept are technology enablers that facilitate gathering and processing of information, supported by communication across diverse environments,...
The continued movement towards converged networks changes the focus to building application services that enable customers to move between different types of service providers based on their needs. Policy management becomes paramount for the rapid deployment and management of these application services. This paper presents the concept of a policy continuum and discusses the importance of modeling...
