UnZip is a small zipfile extract utility. It is written to be assmall portable as possible and is intended to be starting point for im-plementation of .ZIP files in non-IBM environments.Source code is provided in C and Turbo Pascal. If you port this programto a non-IBM system, I would appreciate a copy of the ported source andexe files.

Client/Server版本 DBISAM compiles directly into your application with no external libraries required.

Client/Server版本 DBISAM compiles directly into your application with no external libraries required. Runtime package support is also provided if so desired. It has a very small footprint and does not require any forms support in Delphi 6, C++Builder 6, and Kylix 2 and higher, which helps keep the size of non-UI applications like services or web applications to a minimum.

SR-tree is an index structure for high-dimensional nearest neighbor queries

SR-tree is an index structure for high-dimensional nearest neighbor queries，C++ sourcecode. SR-tree outperforms the R*-tree and the SS-tree especially for high-dimensional and non-uniform data which are likely to appear in the actual image / video applications.

prolog 找路例子程序： === === === === === === Part 1-Adding connections Part 2-Simple Path example

prolog 找路例子程序： === === === === === === Part 1-Adding connections Part 2-Simple Path example | ?- path1(a,b,P,T). will produce the response: T = 15 P = [a,b] ? Part 3 - Non-repeating path As an example, the query: ?- path2(a,h,P,T). will succeed and may produce the bindings: P = [a,depot,b,d,e,f,h] T = 155 Part 4 - Generating a path below a cost threshold As an example, the query: ?- path_below_cost(a,[a,b,c,d,e,f,g,h],RS,300). returns: RS = [a,b,depot,c,d,e,g,f,h] ? RS = [a,c,depot,b,d,e,g,f,h] ? no ==================================

The tar file contains the following files: ptfsf.c: heart of the perfect TFSF code ptfsf.h: header file for same ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file fdtdgen.h: defines macros used in much of my code Makefile: simple make-file to compile programs Also include are some simple script files to run the programs with reasonable values. The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
