This paper proposes a new method for online secondary path modeling in feedback active noise control (ANC) systems. In practical cases, the secondary path is usually time-varying. For these cases, online modeling of secondary path is required to ensure convergence of the system. In literature the secondary path estimation is usually performed offline, prior to online modeling, where in the prop...

The use of performance analysis and prediction techniques by software designers and software engineers is at best inconsistent and at worst simply does not happen. This is principally because these techniques are seen as separate and diicult to apply. Work on Software Performance Engineering, initiated by Smith, has sought to bridge the gap, but has had limited success. With the emergence of a ...

the performance of water flooding can be investigated by using either detail numerical modeling or simulation, or simply through the analytical buckley-leverett (bl) model. the buckley-leverett analytical technique can be applied to one-dimensional homogeneous systems. in this paper, the impact of heterogeneity on water flooding performance and fractional flow curve is investigated. first, a ba...

Ideally, a software development methodology should include both the ability to specify non-functional requirements and to analyze them starting early in the lifecycle; the goal is to verify whether the system under development would be able to meet such requirements. This chapter considers quantitative performance analysis of UML software models annotated with performance attributes according t...

—Performance measurement and analysis is crucial for steering the organization to realizing its strategic and operational goals. Relevant performance indicators and their relationships to goals and activities need to be determined and analyzed. Current organization modeling approaches do not reflect this in an adequate way. This paper attempts to fill the gap by presenting a framework for model...

The goals of this work were to evaluate the methods used for assessing surgical residents and to model surgical resident performance. Currently, residents are evaluated by the attending surgeons using a one-page paper evaluation form after each rotation in a particular department. These subjective questionnaires require the evaluators to rate residents in competency areas that are thought to de...

To my grandparents. iii ACKNOWLEDGMENTS I would like to thank my adviser, Nicholas P. Carter, for his guidance and support all through my graduate study. Many thanks to my project team members, Hillery C. Hunter and Azmat Hussain, who have contributed to this work in many ways.
