Foreword by .NET Remoting guru Ingo Rammer BACK IN 1999, the ACM published a study that presented a comparison of 40 independent implementations of a computationally intensive problem, created by different programmers in either Java the then-current managed runtime environmentor C/C++. It concluded with the finding that interpersonal differences between the developers "are much larger than the average difference between Java and C/C++" and that "performance ratios of a factor of 30 or more are not uncommon between the median programs from the upper half versus the lower half." This should teach you something: If you are not a guru-level C++ programmer, then the chance is quite high that a managed code implementation performs as well as the average C++ solution, especially given the fact that most .NET languages simply allow you fewer possibilities to introduce subtle memory related or performance-related issues. And keep in mind that this study was conducted several years ago, and that Just-In-Time Compilation (JIT) as well as memory management and garbage collection (GC) technologies have been improved in the meantime! This, however, doesn't mean that you can't create horribly slow, memory-eating applications with .NET. That's why you should be really concerned about the other part of the study's conclusion, namely that "interpersonal differences . . . are much larger." In essence, this means that you have to know about how to optimize your applications so that they run with the expected performance in a managed environment. Even though .NET frees you from a lot of tasks that in C++ would have been your responsibility as a developer, these tasks still exist; these "little puppets" have only cleared the main stage and now live in some little corner behind the scenes. If you want your application to run in the top performance range, you will still need to find the right strings to pull to move these hidden figures and tobasically keep them out of the way of negatively affecting your application's performance. (Lutz Prechtelt, "Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences," Communications of the ACM 42, no. 10 [October 1999]: 109–112.) But knowing about the common language runtime's internals is still not enough, as lots of performance issues actually turn up during application design and not just during the coding stage. Collections, remoting, interoperability with unmanaged code, and COM components are not the only things that come to my mind in this regard. It is the aim of Nick's book to enable you to understand the design issues as well as the underlying CLR mechanisms in order to create the programs that run on the better side of the 30-times performance difference quoted in the ACM study. Nick really managed to create a book that addresses these issues, which will otherwise turn up when carelessly coding to a managed environment. This book will allow you to get into the details without being overwhelmed by the underlying complexity of the common language runtime. The only thing you have to resist after reading the book is the urge to over-optimize your code. I was delighted to see that Nick begins with a discussion of identifying an application's performance-critical sections and only later turns towards isolating and resolving these real performance bottlenecks. This is, in my opinion, one of the most important tasks—and also one of the most complex ones—when working with large-scale applications. And now, read on, and enjoy the ride to the better side of a 30-fold performance difference. Ingo Rammer, author of Advanced .NET Remoting Vienna, Austria http://www.ingorammer.com About the Book Maximizing .NET Performance is the first book dedicated entirely to providing developers and architects with information on .NET Framework performance. .NET is atechnology with a vast surface area, and coverage of every aspect of performance relevant to all .NET technologies is not possible within a single volume. This book concentrates on the performance of .NET Framework technologies like garbage collection, .NET Remoting, and Code Access Security. Because these technologies form the building blocks upon which all .NET applications run, the information in this book is relevant to all .NET developers. In addition to providing high-level material on achieving software with good performance characteristics, the books aims to enhance your knowledge of the design and implementation of the framework, and to provide the tools and techniques to allow you to conduct your own investigation into performance problems. Rather than taking a "tips and tricks" approach, the book aims to provide a detailed exploration of each topic and explore the "why" and "by how much" aspects of performance that are often overlooked.

This book concisely presents the optimization process and optimal control process with examples and simulations to help self-learning and better comprehension. It starts with function optimization and constraint inclusion and then extends to functional optimization using the calculus of variations. The development of optimal controls for continuous-time, linear, open-loop systems is presented using Lagrangian and Pontryagin-Hamiltonian methods, showing how to introduce the end-point conditions in time and state. The closed-loop optimal control for linear systems with a quadratic cost function, well-known as the linear quadratic regulator (LQR) is developed for both time-bound and time-unbounded conditions. Some control systems need to maximize performance alongside cost minimization. The Pontryagin's maximum principle is presented in this regard with clear examples that show the practical implementation of it. It is shown through examples how the maximum principle leads to control switching and Bang-Bang control in certain types of systems. The application of optimal controls in discrete-time open-loop systems with the quadratic cost is presented and then extended to the closed-loop control, which results in the model predictive control (MPC). Throughout the book, examples and Matlab simulation codes are provided for the learner to practice the contents in each section. The aligned lineup of content helps the learner develop knowledge and skills in optimal control gradually and quickly.

This paper reports for uncovered interest parity (UIP) using daily data for 23 developing and developed countries during the crisis-strewn 1990s. UIP is a classic topic of international finance, a critical building block of most theoretical models, and a dismal empirical failure. UIP states that the interest differential is, on average, equal to the ex post exchange rate change. UIP may work differently for countries in crisis, whose exchange and interest rates both display considerably more volatility. This volatility raises the stakes for financial markets and central banks; it also may provide a more statistically powerful test for the UIP hypothesis. Policy-exploitable deviations from UIP are, therefore, a necessary condition for an interest rate defense. There is a considerable amount of heterogeneity in the results, which differ wildly by country.
