This structure defines the interface between the low-level tty driver and the tty routines. The following routines can be defined unless noted otherwise, they are optional, and can be filled in with a null pointer.
A C++ N-grams Package 2.0
This is a simple C++ n-grams package that includes a header, the corresponding cpp file, and a sample driver program. It is a natural language processing tool for creating n-gram profiles for text documents. The details on usage is documented in the header right above each public function defined. This package is based on Dr. Vlado Keselj s Perl package Text::Ngrams which is available in CPAN.
zemax源碼:
This DLL models a standard ZEMAX surface type, either plane, sphere, or conic
The surface also demonstrates a user-defined apodization filter
The filter is defined as part of the real ray trace, case 5
The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y.
The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)]
The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)]
where
x^2 + y^2 = r^2
R = semi-diameter
The tranmitted intensity is maximum in the center.
T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.
% This program calculates radar ranges in a jamming environment. It works
% with both Stand-off jamming and self-screening jamming for steady and Swerling type
% targets with frequency agility, coherent integration and standard atmosphere/rain

LINEINTRGAL Line Integral in a 2D Vector Field.
LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C.
X and Y define the coordinates of a rectangular grid over which
U and V are defined. X and Y must be monotonic and 2D plaid as
% produced by MESHGRID. X, Y, U, and V must all be the same size.
C++ Standard Library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, however, is not self-explanatory. To make full use of its components-and to benefit from their power-you need a resource that does far more than list the classes and their functions.
The C++ Standard Library not only provides comprehensive documentation of each library component, it also offers clearly written explanations of complex concepts, describes the practical programming details needed for effective use, and gives example after example of working code.
In this paper, we describe the development of a mobile butterfly-watching learning (BWL)
system to realize outdoor independent learning for mobile learners. The mobile butterfly-watching
learning system was designed in a wireless mobile ad-hoc learning environment. This is first result
to provide a cognitive tool with supporting the independent learning by applying PDA with
wireless communication technology to extend learning outside of the classroom. Independent
learning consists of self-selection, self-determination, self-modification, and self-checking.
