Download or read book Real time PDE constrained Optimization written by Lorenz T. Biegler and published by SIAM. This book was released on 2007-01-01 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many engineering and scientific problems in design, control, and parameter estimation can be formulated as optimization problems that are governed by partial differential equations (PDEs). The complexities of the PDEs--and the requirement for rapid solution--pose significant difficulties. A particularly challenging class of PDE-constrained optimization problems is characterized by the need for real-time solution, i.e., in time scales that are sufficiently rapid to support simulation-based decision making. Real-Time PDE-Constrained Optimization, the first book devoted to real-time optimization for systems governed by PDEs, focuses on new formulations, methods, and algorithms needed to facilitate real-time, PDE-constrained optimization. In addition to presenting state-of-the-art algorithms and formulations, the text illustrates these algorithms with a diverse set of applications that includes problems in the areas of aerodynamics, biology, fluid dynamics, medicine, chemical processes, homeland security, and structural dynamics. Audience: readers who have expertise in simulation and are interested in incorporating optimization into their simulations, who have expertise in numerical optimization and are interested in adapting optimization methods to the class of infinite-dimensional simulation problems, or who have worked in "offline" optimization contexts and are interested in moving to "online" optimization.

Download or read book Tools and Methods for Analysis Debugging and Performance Improvement of Equation Based Models written by Martin Sjölund and published by Linköping University Electronic Press. This book was released on 2015-05-11 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equation-based object-oriented (EOO) modeling languages such as Modelica provide a convenient, declarative method for describing models of cyber-physical systems. Because of the ease of use of EOO languages, large and complex models can be built with limited effort. However, current state-of-the-art tools do not provide the user with enough information when errors appear or simulation results are wrong. It is of paramount importance that such tools should give the user enough information to correct errors or understand where the problems that lead to wrong simulation results are located. However, understanding the model translation process of an EOO compiler is a daunting task that not only requires knowledge of the numerical algorithms that the tool executes during simulation, but also the complex symbolic transformations being performed. As part of this work, methods have been developed and explored where the EOO tool, an enhanced Modelica compiler, records the transformations during the translation process in order to provide better diagnostics, explanations, and analysis. This information is used to generate better error-messages during translation. It is also used to provide better debugging for a simulation that produces unexpected results or where numerical methods fail. Meeting deadlines is particularly important for real-time applications. It is usually essential to identify possible bottlenecks and either simplify the model or give hints to the compiler that enable it to generate faster code. When profiling and measuring execution times of parts of the model the recorded information can also be used to find out why a particular system model executes slowly. Combined with debugging information, it is possible to find out why this system of equations is slow to solve, which helps understanding what can be done to simplify the model. A tool with a graphical user interface has been developed to make debugging and performance profiling easier. Both debugging and profiling have been combined into a single view so that performance metrics are mapped to equations, which are mapped to debugging information. The algorithmic part of Modelica was extended with meta-modeling constructs (MetaModelica) for language modeling. In this context a quite general approach to debugging and compilation from (extended) Modelica to C code was developed. That makes it possible to use the same executable format for simulation executables as for compiler bootstrapping when the compiler written in MetaModelica compiles itself. Finally, a method and tool prototype suitable for speeding up simulations has been developed. It works by partitioning the model at appropriate places and compiling a simulation executable for a suitable parallel platform.

Download or read book First in the Field written by Robin Lea Pyle and published by Purdue University Press. This book was released on 2019-07-15 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: First in the Field: Breaking Ground in Computer Science at Purdue University chronicles the history and development of the first computer science department established at a university in the United States. The backdrop for this groundbreaking academic achievement is Purdue in the 1950s when mathematicians, statisticians, engineers, and scientists from various departments were searching for faster and more efficient ways to conduct their research. These were fertile times, as recognized by Purdue’s President Frederick L. Hovde, whose support of what was to become the first “university-centered” computer center in America laid the foundation for the nation’s first department of computer science.The book pulls together strands of the story from previously unpublished texts and photographs, as well as published articles and interviews, to provide the first complete historical account of the genesis of the Department of Computer Sciences at Purdue, and its continued growth up to the present. It is a fascinating story with parallels to the “space race,” involving many players, some of whose contributions have gone previously unacknowledged in the heat of the race. Filled with unique historical anecdotes detailing the challenges of legitimizing the new academic field, these stories bring to life the strong convictions of a group of pioneering thinkers that continue to resonate for us today. The raw determination required to transform a computing laboratory that offered early programming courses into a full-fledged computer center and a department offering degrees in computer science characterizes this story of interest to anyone intrigued by the pathways creativity takes in scientific endeavors. It is a story that matters because it was, and is, an ongoing achievement of leadership in education and research in a field that has totally revolutionized our society.
