megahal is the conversation simulators conversing with a user in natural language. The program will exploit the fact that human beings tend to read much more meaning into what is said than is actually there
MegaHAL differs from conversation simulators such as ELIZA in that it uses
a Markov Model to learn how to hold a conversation. It is possible to
teach MegaHAL to talk about new topics, and in different languages.
wavelets are used extensively in signal and image processing,Medicine, Finance, Radar, Sonar, Geology
and many other varied fields. They are usually presented in mathematical formulae, but can actually be
understood in terms of simple comparisons with your data.
Many applications in computer graphics require complex, highly
detailed models. However, the level of detail actually necessary
may vary considerably. To control processing time, it is often desirable
to use approximations in place of excessively detailed models.
Writing Your First ASP Application ( Quick Start )
(Page 1 of 8 )
There are many tutorials out there that show you how to program in ASP. Some of them are good, and some are bad. Some of them are downright terrible. In any case, you ve read a bit about ASP and now you are ready to build your first application. But where do you start?
In my own experience, I have found that I find it easier to learn something if I actually work with it hands-on. Just reading a book or documentation doesn’t give you the practical knowledge you need to be able to rush off and start creating applications.
In this article, I will discuss the creation of a very simple application. I will cover what the application will do, how we will approach writing it, demonstrate in code how we will do it, and discuss additional features that could be added to it.

Universal Serial Bus (USB) is a communications architecture that gives a personal
computer (PC) the ability to interconnect a variety of devices using a simple four-
wire cable. The USB is actually a two-wire serial communication link that runs at
either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices
at startup or when they are plugged in at run time. These devices are broken into
various device classes. Each device class defines the common behavior and
protocols for devices that serve similar functions. Some examples of USB device
classes are shown in the following table
//
// Histogram Sample
// This sample shows how to use the Sample Grabber filter for video image processing.
// Conceptual background:
// A histogram is just a frequency count of every pixel value in the image.
// There are various well-known mathematical operations that you can perform on an image
// using histograms, to enhance the image, etc.
// Histogram stretch (aka automatic gain control):
// Stretches the image histogram to fill the entire range of values. This is a "point operation,"
// meaning each pixel is scaled to a new value, without examining the neighboring pixels. The
// histogram stretch does not actually require you to calculate the full histogram. The scaling factor
// is calculated from the minimum and maximum values in the image.

"There is No Free Lunch"
Time Limit: 1 Second Memory Limit: 32768 KB
One day, CYJJ found an interesting piece of commercial from newspaper: the Cyber-restaurant was offering a kind of "Lunch Special" which was said that one could "buy one get two for free". That is, if you buy one of the dishes on their menu, denoted by di with price pi , you may get the two neighboring dishes di-1 and di+1 for free! If you pick up d1, then you may get d2 and the last one dn for free, and if you choose the last one dn, you may get dn-1 and d1 for free.
However, after investigation CYJJ realized that there was no free lunch at all. The price pi of the i-th dish was actually calculated by adding up twice the cost ci of the dish and half of the costs of the two "free" dishes. Now given all the prices on the menu, you are asked to help CYJJ find the cost of each of the dishes.
Whenever there is an application to write, breaking it up to small pieces is a great idea. The smallest piece of any application would probably be a data object, or a simple Bean in Java. Java Beans are simple Java classes that have a distinctive look and behavior. Their simplest purpose is to contain data and they accomplish this by having properties. Each property is actually a data-member containing/referencing the actual data and a couple of methods, a getter method and a setter method. Thus, the simplest data-bean describing a person could be expressed as such:
To review what a metaball is, and how to render them and to describe a
new optimization I ve made for rendering metaballs. For complex scenes,
it can render hundreds of times faster, though I m certain others have
discovered this trick as well. It does very slightly change the
characteristic shape of the blobs, but there is no loss in image quality
whatsoever. (I actually developed all this about two years ago, but just
now felt like writing it all down, and had the time!)
Algorithms for programmers
This draft is intended to turn into a book about selected algorithms. The audience in mind are programmers
who are interested in the treated algorithms and actually want to have/create working and
reasonably optimized code.
