Figure 1-1: The .NET experience Once useful services can be consumed from many devices, the typical end user will find them more useful, and their acceptance will become more widespread. If you can offer customers the same solution that can be used in the office or on the cell phone when they are away from the office, I think the selling part will not be how much, but when. From the developer viewpoint, the .NET experience is equally as important as the end user. If this stuff is going to be a pain in the neck to develop, you will never use it. The good news is that Microsoft realized that, and created the tools that developers like yourself need to create great Web- and Windows-based applications faster and easier than you have ever developed applications before. With Visual Studio .NET, you have the tools you need to leverage your existing knowledge to create applications for .NET. Visual Basic has always been known for providing the developer with the most efficient IDE for developing Windows-based applications. With the introduction of Visual InterDev, Microsoft tried to create the same ease-of-use GUI for creating Web-based applications. If you have ever used InterDev, you know that it fell short in being the Rapid Application Development (RAD) tool for the Internet it was promised to be. Visual Studio .NET is truly RAD for the Internet. With the best of all worlds, from Visual Basic to InterDev to FrontPage to any other GUI tool you have ever used, Visual Studio .NET is a combination of everything great Microsoft has ever produced in a development environment. If you are like me, you do not have time to learn brand new stuff. You have enough to do at work as it is, let alone learn about SOAP and how to make it work with .NET. With Visual Studio .NET, XML is "baked" in; it is everywhere, and you do not have to know where or how. Everything to the developer is transparent; all you need to worry about is coding. The plumbing that goes into marshalling XML from client to server is not an issue. I mentioned RAD for the Internet, but VS .NET is also RAD for the server. It is a unified environment for developing client- and server-based applications and services, in just about any language you choose to use, faster and easier than ever. And best of all, it is based on standards that are in place today, such as XML, SOAP, HTTP, and HTML. Let's get into some details about what makes up .NET and how you can actually use it.

Sketch relations in 3D sketches are not exactly the same as in 2D sketches. Improvements have been made in the past several versions, but 3D sketches still lack some important bits of functionality. Pierce is not applicable in a 3D sketch, and is replaced by Coincident, because in 3D sketches, there is no difference between Pierce and Coincident. Relations are not projected into a plane in a 3D sketch the way they are in 2D. On the other hand, several other relations are available in 3D sketches that are not found in 2D sketches, such as AlongX, AlongY, AlongZ, and OnSurface. As mentioned earlier, relations in 3D sketches are not projected like they are in 2D sketches. For example, an entity in a 2D sketch can be made coincident to an entity that is out of plane. This is because to make the relation, the out-of-plane entity is projected into the sketch plane, and the relation is made to the projection. In a 3D sketch, Coincident means Coincident, with no projection. As a general caution, keep in mind that solving sketches in 3D is more difficult than it is in 2D. You will see more situations where sketch relations fail, or flip in the wrong direction. Angle dimensions in particular are notorious in 3D sketches for flipping direction if they change and go across the 180-degree mark. When possible, it is advisable to work with fully defined sketches, and also to be careful (and conservative) with sketch relations.

element of the matrix, R, N complex multiplicationsand N - 1 complex additions must be performed, where N is the sample size, in bits, used to generate the cross-correlation matrix, R. Due to the Hermitian nature of the matrix, R, it is only necessary to execute these instructions L ( L 1 ) / 2 times, rather than L2 times, as would be expected. Therefore, N L (L 1 )/ 2 complex multiplications L(L 1)( N - 1)/ 2 complex addiand tions are required for forming matrix, leading to total of L ( L 1) (2N 1 ) / 2 complex the a operations. However, upon assuming that a Multiply-and-Accumulate(MAC) instruction exists in the implementation, complexity figure reduces to N L (L+1). The Hermitian this crosscorrelation matrix,R, must then be inverted requiring L3/2 L2 complex operations[244], rather than the usual L3 operations required for a non-Hermitian matrix. In order to calculate the correlation between the reference signal and the array output vector requires a furtherL complex multiplicationsand L - 1 complex additions, reducing to complex operationsasL suming a MAC instruction. Then, fromthe inverted matrix, R-', and the correlation vector, -, the weight vector, W , may be obtained after L complex operations. Therefore,the total z ' complexity of the SMI beamforming algorithmLisL 1)(2N- l)/2+L3/2+ +2L - 1 ( 2L2 complex operations. The ULMS adaptive beamformer requires only 2L 1 complex multiplications and 2L complex additions per iteration, rendering it the least complex algorithm. However, the NLMS technique is more practical, since its performance is less dependent upon the input power. The additional complexity associated with this algorithm is the L 1 complex multiplications requiredfor calculating the current value of p. Therefore, the final complexity of the NLMS algorithm is equivalent to 3L 2 complex multiplicationsand 3L complex addi-

where CP is a constant. However, the phases i vary strongly, and are thus approximated as random variables that are uniformly distributed in the range [0, 2 ]. The real part of the received eld strength due to the ith MPC is thus |ai | cos( i ), the imaginary part is |ai | sin( i ). Furthermore, we need to consider the Doppler shift for computation of the total eld strength E(t). If we look at an unmodulated carrier, we get (in real passband notation):

The transaction must be atomic, meaning all or nothing. At the end of the transaction, either all of the transaction is successful, or all of the transaction fails. If a partial transaction is written to disk, the atomic property is violated.

n Balloon Size Options: Balloon size settings range from one to five characters, as well as a Tight Fit setting, which enables the balloon to resize automatically, depending on its contents. The other settings are fixed sizes, regardless of contents. n Balloon Text: The Upper and Lower settings are only used at the same time if the style is Circular Split Line. Default settings are Item Number for the Upper setting and Quantity for the Lower setting. If you use a style other than split balloon, then the Upper setting represents the only value inside the balloon. The options for balloon text are as follows: n Text: The Text selection enables the user to enter custom text into the balloon. n Item Number: This option pulls the Item Number from the BOM. This is typically related to the order of a component in an assembly. When connected to a part in a
