数学建模，美国赛，可以参考下 Summary This paper describes model testing of baseball bats with the purpose of finding the so-called “sweet spot”. We establish two models and solve three problems. Basic model describes sweet spot which isn’t this spot at the end of the bat and helps explain this empirical finding. It predicts different behavior for wood (usually ash) or metal (usually aluminum) bats and explains Major League Baseball prohibits metal bats. Improved model proves that corking a bat enhances the sweet spot effect and explains Major League Baseball prohibits corking.

Version 2.0 of the .NET Framework will offer powerful enhancements to ADO.NET that will give application and service developers unprecedented control over their data. In A First Look at ADO.NET and System.Xml v. 2.0, Microsoft's lead program manager on XML technologies joins with two leading .NET and XML experts to present a comprehensive preview of tomorrow's ADO.NET and System.Xml classes. Drawing on the first .NET Framework 2.0 Technology Preview Release, the authors introduce powerful new techniques for simplifying development, enhancing flexibility, and leveraging .NET's new support for emerging XML standards. They also preview important new synergies between .NET Framework 2.0, XML, and the next version of SQL Server (code-named "Yukon"). This book's detailed coverage includes: Clear explanations of Microsoft's data-access intentions and directions--so you'll be ready when .NET 2.0 arrives A brief overview of ObjectSpaces--the exciting new technology for using objects that represent and hold their own data Major improvements in bulk loading, batch execution, and paging Support for truly asynchronous connection and command operations In-process server-side cursors for programmatic data processing within stored procedures XML class improvements that enhance standards support, promote integration, and maximize performance Beyond SQLXML 3.0: leveraging XQuery and XML Views in distributed query processing Better support for storing XML data and integrating relational and XML data management "Yukon's" new XML data type: using SQL Server as an XML document store Whether or not you're already developing with ADO.NET, this book brings together all the insights, best practices, and sample code you'll need to get a running start with ADO.NET 2.0 and the System.Xml v. 2.0 classes.
