Eliminate the hassles of Active Directory - install Windows 2000 without it!Windows 2000 is undoubtedly a great product. In one year after its release, Microsoft have sold have sold 10 million licenses. System administrators are praising its impressive abilities to coordinate Internet, intranet, extranets, and management applications creating a complete technical infrastructure.  However, there has been a noticeable amount of organizations that are avoiding one of the most talked about features of Windows 2000 - Active Directory. The industry buzz is that Active Directory (although a great

Sommario/riassunto

The finite element method is a technique for solving problems in applied science and engineering. The essence of this book is the application of the finite element method to the solution of boundary and initial-value problems posed in terms of partial differential equations. The method is developed for the solution of Poisson's equation, in a weighted-residual context, and then proceeds to time-dependent and nonlinear problems. The relationship with the variational approach is alsoexplained. This book is written at an introductory level, developing all the necessary concepts where required. Co
