| fly by wire vs mechanical: Methods and Procedures for the Verification and Validation of Artificial Neural Networks Brian J. Taylor, 2006-03-20 Neural networks are members of a class of software that have the potential to enable intelligent computational systems capable of simulating characteristics of biological thinking and learning. Currently no standards exist to verify and validate neural network-based systems. NASA Independent Verification and Validation Facility has contracted the Institute for Scientific Research, Inc. to perform research on this topic and develop a comprehensive guide to performing V&V on adaptive systems, with emphasis on neural networks used in safety-critical or mission-critical applications. Methods and Procedures for the Verification and Validation of Artificial Neural Networks is the culmination of the first steps in that research. This volume introduces some of the more promising methods and techniques used for the verification and validation (V&V) of neural networks and adaptive systems. A comprehensive guide to performing V&V on neural network systems, aligned with the IEEE Standard for Software Verification and Validation, will follow this book. |

| fly by wire vs mechanical: Advanced Public Procurement as Industrial Policy Gunnar Eliasson, 2010-03-10 This study is about the macroeconomic effects of positive externalities or industrial spillovers around advanced production. The case explored is the “technology di- dend” around Swedish aircraft industry, and in particular around the aircraft ma- facturer Saab, and the major industrial project of the JAS 39 Gripen multirole combat aircraft. The project is partly an updating of my book (in Swedish) Technology 1 Generator or a National Presige Project from 1995, but extends the analysis in s- eral directions. The study includes a chapter on spillovers from advanced production in an industrially developing economy, South Africa, that has acquired the JAS 39 Gripen for its Air Force. There is also a chapter in which the results for Sweden are discussed in the wider context of advanced public procurement in Europe. The text has been organized such that the main chapters have been written for academic readers. Two supplements include the technical details of data collection, mathematical models, and calculation methods. The first chapter is brief and focused on the results. It has the character of an extended executive summary. The second chapter summarizes the entire story; problems, results, and methods. This project would not have been possible without the generous support of a number of people. First of all great thanks go to all those people with crowded calendars in Swedish industrial firms that have set aside time to respond to my questions. Most of them have been listed at the end of the book. |
