Modeling and analysis of security trade-offs – A goal oriented approach

The challenges in developing non-functional requirements (NFRs) for an application platform go much beyond those for a single application system. To derive platform NFRs from NFR specifications of different domain applications, requirements analysts must deal with much variation of domain specific NFRs, with different deployment configurations and load conditions, with different NFR related trade-offs, as well as with different terminology and metric definitions. This chapter presents a platform NFR development method that supports dealing with the aforementioned challenges. The presented method offers a goal- and scenario-oriented modeling and analysis technique that supports dealing with qualitative and quantitative NFRs during platform NFR development in an integrated way. The platform NFR development method was used to develop NFRs of a service-oriented application platform for three different application domains in an industrial setting.

Do So

AbstractThe person-oriented approach seeks to match theories and methods that portray development as a holistic, highly interactional, and individualized process. Over the past decade, this approach has gained popularity in developmental psychopathology research, particularly as model-based varieties of person-oriented methods have emerged. Although these methods allow some principles of person-oriented theory to be tested, little attention has been paid to the fact that these methods cannot test other principles, and may actually be inconsistent with certain principles. Lacking clarification regarding which aspects of person-oriented theory are testable under which person-oriented methods, assumptions of the methods have sometimes been presented as testable hypotheses or interpreted as affirming the theory. This general blurring of the line between person-oriented theory and method has even led to the occasional perception that the method is the theory and vice versa. We review assumptions, strengths, and limitations of model-based person-oriented methods, clarifying which theoretical principles they can test and the compromises and trade-offs required to do so.

Modular Composition

This book provides an accessible introduction to the principles and tools for modeling, analyzing, and synthesizing biomolecular systems. It begins with modeling tools such as reaction-rate equations, reduced-order models, stochastic models, and specific models of important core processes. It then describes in detail the control and dynamical systems tools used to analyze these models. These include tools for analyzing stability of equilibria, limit cycles, robustness, and parameter uncertainty. Modeling and analysis techniques are then applied to design examples from both natural systems and synthetic biomolecular circuits. In addition, the book addresses the problem of modular composition of synthetic circuits, the tools for analyzing the extent of modularity, and the design techniques for ensuring modular behavior. It also looks at design trade-offs, focusing on perturbations due to noise and competition for shared cellular resources. Featuring numerous exercises and illustrations throughout, the book is the ideal textbook for advanced undergraduates and graduate students. For researchers, it can also serve as a self-contained reference on the feedback control techniques that can be applied to biomolecular systems.
