In response to constant pressure to design more efficient, faster, smaller, and better systems, engineers are constantly looking for ways to improve existing designs or replace them with better ones. Facing large fuel costs, the aerospace industry in particular has been researching alternative designs to increase fuel efficiency and performance. One such alternative is the development of reconfigurable aircraft wings. These wings would be able to adapt to the current environment increasing lift or reducing drag when appropriate.
This book explains how to write device drivers for the newest members of the MicrosoftWindows family of operating systems using the Windows Driver Model (WDM). In this Introduction, I ll explain who should be reading this book, the organization of the book, and how to use the book most effectively. You ll also find a note on errors and a section on other resources you can use to learn about driver programming. looking ahead, Chapter 1 explains how the two main branches of the Windows family operate internally, what a WDM device driver is, and how it relates to the rest of Windows.
Learn to build applications with Jakarta Struts, the most popular JSP development framework. Struts Kick Start is a "hands-on" book filled with sample applications and code snippets you can reuse, and in-depth coverage of new features in Struts 1.1. If you are looking for a practical book that "shows you how to do it", then Struts Kick Start is for you. Plus, it s the first Struts book with detailed examples of the major Struts tags
This is a PHP search engine. It searches for text
and then displays results. At the time I completed it
it was the first of its kind. I spent many hours
looking for something like it, but could not find
anything. It searches the directory you put it in.
Basic function to locate and measure the positive peaks in a noisy
data sets. Detects peaks by looking for downward zero-crossings
in the smoothed third derivative that exceed SlopeThreshold
and peak amplitudes that exceed AmpThreshold. Determines,
position, height, and approximate width of each peak by least-squares
curve-fitting the log of top part of the peak with a parabola.
This book was intended specifically for people who know how to program already but have taken only rudimentary
stabs at graphics/game programming or never taken any stab at all, such as programmers in another field or college
students looking to embark on some side projects.
You may read code because you have to-to fix it, inspect it, or improve it. You may read code the way an engineer examines a machine--to discover what makes it tick. Or you may read code because you are scavenging--looking for material to reuse.
Code-reading requires its own set of skills, and the ability to determine which technique you use when is crucial. In this indispensable book, Diomidis Spinellis uses more than 600 real-world examples to show you how to identify good (and bad) code: how to read it, what to look for, and how to use this knowledge to improve your own code.
Fact: If you make a habit of reading good code, you will write better code yourself.
This book is for merging practical electronic
devices with the Internet, for hardware and software designers looking to expand their
skills of JAVA programming.This book is a complete introduction to Internet-enabled devices,it provide all of the information to inexpensively build web-enabled hardware.
Collection of key-value pairs.
TDictionary represents a generic collection of key-value pairs.
This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality operation, and initial content.
You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all key-value pairs. Adding or removing a key-value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison operation for keys.
You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods.
The Items property lists all Count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value.
The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.
Introduction
jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second.
jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html
