Download or read book Workload sensitive Timing Behavior Analysis for Fault Localization in Software Systems written by Matthias Rohr and published by BoD – Books on Demand. This book was released on 2015-02-09 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software timing behavior measurements, such as response times, often show high statistical variance. This variance can make the analysis difficult or even threaten the applicability of statistical techniques. This thesis introduces a method for improving the analysis of software response time measurements that show high variance. Our approach can find relations between timing behavior variance and both trace shape information and workload intensity information. This relation is used to provide timing behavior measurements with virtually less variance. This can make timing behavior analysis more robust (e.g., improved confidence and precision) and faster (e.g., less simulation runs and shorter monitoring period). The thesis contributes TracSTA (Trace-Context-Sensitive Timing Behavior Analysis) and WiSTA (Workload-Intensity-Sensitive Timing Behavior Analysis). TracSTA uses trace shape information (i.e., the shape of the control flow corresponding to a software operation execution) and WiSTA uses workload intensity metrics (e.g., the number of concurrent software executions) to create context-specific timing behavior profiles. Both the applicability and effectiveness are evaluated in several case studies and field studies. The evaluation shows a strong relation between timing behavior and the metrics considered by TracSTA and WiSTA. Additionally, a fault localization approach for enterprise software systems is presented as application scenario. It uses the timing behavior data provided by TracSTA and WiSTA for anomaly detection.

This book was released on 2007-05-08 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. MOTIVATION In many physical situations, a plant model is often provided with a qualitative or quantitative measure of associated model uncertainties. On the one hand, the validity of the model is guaranteed only inside a frequency band, so that nearly nothing can be said about the behavior of the real plant at high frequencies. On the other hand, if the model is derived on the basis of physical equations, it can be parameterized as a function of a few physical parameters, which are usually not perfectly known in practice. This is e.g. the case in aeronautical systems: as an example, the ae- dynamic model of an airplane is derived from the flight mechanics eq- tions. When synthesizing the aircraft control law, it is then necessary to take into account uncertainties in the values of the stability derivatives, which correspond to the physical coefficients of the aerodynamic model. Moreover, this airplane model does not perfectly represent the be- vior of the real aircraft. As a simple example, the flight control system or the autopilot are usually synthesized just using the aerodynamic model, thus without accounting for the flexible mechanicalstructure: the c- responding dynamics are indeed considered as high frequency neglected 1 dynamics, with respect to the dynamics of the rigid model .

Download or read book Policy Analysis by Design written by Davis Bobrow and published by University of Pittsburgh Pre. This book was released on 2010-09-24 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Policy analysts currently have available to them a cafeteria menu of analytical approaches, from welfare economics to political philosophy. Davis B. Bobrow and John S. Dryzek believe that now more than ever a clear understanding of the approaches available - the assumptions consciously or unconsciously adopted by their practitioners - is crucial to the practice of intellectually defensible and socially responsible analysis of public policy.Policy Analysis by Design examines the approaches to public policy taken by those who try to teach it, write about it, and influence it through major analysis. Bobrow and Dryzek systematically compare the five major contending analytical frames of reference: welfare economics, public choice, social structure, information processing, and political philosophy. The workings of each frame are illustrated by means of a common, if imaginary, policy case - air pollution in the hypothetical Smoke Valley.Bobrow and Dryzek discover that many important distinctions emerge among the major frames of reference, differences which should help to determine when to choose what approach. The authors conclude by suggesting how policy analysis should be conducted, and how policy analysts should be trained, in the face of such diversity.The concerns of Policy Analysis by Design are deeper and broader than most books in the field, breaking new ground. Bobrow and Dryzek make the case that policy analysts should balance their attention to technique with an understanding of the rationales underlying their interventions in policy processes. Policy Analysis by Design, based on this fundamental principle, should stimulate debate about basic choices that policy analysts must make.

Download or read book Neuroergonomics written by Raja Parasuraman and published by Oxford University Press. This book was released on 2006-11-16 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroergnomics can be defined as the study of brain and behavior at work. It combines two disciplines -- neuroscience, the study of brain function, and human factors, the study of how to match technology with the capabilities and limitations of people so they can work effectively and safely. The goal of merging these two fields is to use the startling discoveries of human brain and physiological functioning both to inform the design of technologies in the workplace and home, and to provide new training methods that enhance performance, expand capabilites, and optimize the fit between people and technology. Research in the area of neuroergonomics has blossomed in recent years with the emergence of noninvasive techniques for monitoring human brain function that can be used to study various aspects of human behavior in relation to technology and work, including mental workload, visual attention, working memory, motor control, human-automation interaction, and adaptive automation. The proposed volume will provide the first systematic overview of this emerging area, describing the theoretical background, basic research, major methods, as well as the new and future areas of application. This collection will benefit a number of readers: the experienced researcher investigating related questions in human facotrs and cognitive neuroscience, the student wishing to get a rapid but systematic overview of the field, and the designer interested in novel approaches and new ideas for application. Researchers in human factors and ergonomics, neuroscience, cognitive psychology, medicine, industrial engineering, and computer science will find this volume useful.

Download or read book On the Higher Order Sheffer Orthogonal Polynomial Sequences written by Daniel J. Galiffa and published by Springer Science & Business Media. This book was released on 2013-01-04 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the Higher-Order Sheffer Orthogonal Polynomial Sequences sheds light on the existence/non-existence of B-Type 1 orthogonal polynomials. This book presents a template for analyzing potential orthogonal polynomial sequences including additional higher-order Sheffer classes. This text not only shows that there are no OPS for the special case the B-Type 1 class, but that there are no orthogonal polynomial sequences for the general B-Type 1 class as well. Moreover, it is quite provocative how the seemingly subtle transition from the B-Type 0 class to the B-Type 1 class leads to a drastically more difficult characterization problem. Despite this issue, a procedure is established that yields a definite answer to our current characterization problem, which can also be extended to various other characterization problems as well. Accessible to undergraduate students in the mathematical sciences and related fields, This book functions as an important reference work regarding the Sheffer sequences. The author takes advantage of Mathematica 7 to display unique detailed code and increase the reader's understanding of the implementation of Mathematica 7 and facilitate further experimentation. In addition, this book provides an excellent example of how packages like Mathematica 7 can be used to derive rigorous mathematical results.
