It s an interface for using huffman trees (data STRucture application) that can be used for compression and a test program with CLI in a form of a menu to test those features.
The book uses a task-oriented STRucture that allows you to work through the steps necessary to install
MySQL 4.1 on Linux and Windows platforms, create and manage MySQL databases, query and manipulate
data stored in those databases, administer the MySQL database management system, and connect to
MySQL databases from your PHP, JSP/Java, and ASP.NET/C# applications.
The next section, which describes the book’s STRucture, provides additional details about the specifics of
what the book covers.
To locate the theory of Lie groups within mathematics, one can say that Lie
groups are groups with some additional STRucture that permits us to apply
analytic techniques such as differentiation in a group theoretic context.

The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection (CMRR of 65dB at 10MHz), therebyforming an extremely versatile gain block STRucture thatminimizes component count in most situations. The dualinput pairs are free to take on independent common modelevels, while the two voltage differentials are summedinternally to form a net input signal.
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to the nature of the substrate material. This needs to be considered as a layered STRucture of epoxy resinand glass fibre. Calculations, using Boundary Element field methods, show that the distribution of the electricfield within this layered STRucture determines the apparent dielectric constant and therefore affects theimpedance. Thus FR4 cannot be considered to be uniform dielectric when calculating differential impedance.
