The stress levels used to analyze critical members and determine an appropriate inventory and operating rating are outlined in AASHTO s Manual for Condition Evaluation of Bridges.

To create a character-based output stream, wrap a Stream object (such as a FileStream) inside a StreamWriter. StreamWriter defines several constructors. One of its most popular is shown here: StreamWriter(Stream stream) Here, stream is the name of an open stream. This constructor throws an ArgumentException if stream is not opened for output and an ArgumentNullException if stream is null. Once created, a StreamWriter automatically handles the conversion of characters to bytes. When you are done with the StreamWriter, you must close it. Closing the StreamWriter also closes the underlying stream. Here is a simple key-to-disk utility that reads lines of text entered at the keyboard and writes them to a file called test.txt. Text is read until the user enters the word stop . It uses a FileStream wrapped in a StreamWriter to output to the file.

the same bit rate. When the incoming streams are asynchronous, they are synchronized to a common higher bit rate by adding additional dummy bits called stuffing bits. This process is called positive justification.

15:

Description Output is appended to the end of file. Creates a new output file. Any preexisting file by the same name will be destroyed. Creates a new output file. The file must not already exist. Opens a preexisting file. Opens a file if it exists, or creates the file if it does not already exist. Opens a preexisting file, but reduces its length to zero.

var posNums = nums.Where(n => n > 0).Select(r => r);

This chapter has shown you how to work with bitmaps in almost the same way as you work with vector art in CorelDRAW. Both vectors and bitmaps can happily coexist in a single document. You can shuffle and rearrange objects as if they were made of the same digital materials, and you do need bitmaps in your work when you re trying to convey any sense of photorealism. Naturally, you re anxious to print all this great stuff you ve done up til now, so that s what 29 holds for you: how to output like a pro, and get everything you designed onscreen using CorelDRAW to look the same way when rendered as ink on paper.

Mach-Zehnder modulators. The LiNbO3 MZ modulator is based on the electro-optic effect in which the influence of an electric field changes the material s refractive index. Figure 22.11 is a schematic diagram of an MZ modulator. An x-cut LiNbO3 crystal is used to fabricate an optical interferometer, which consists of an input optical waveguide that splits into two waveguides (at the Y-junction in Figure 22.11). Each arm (waveguide) of the interferometer has an electrode to apply an ac voltage. The two arms combine at the output Y-junction to form the output waveguide.
