We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, while the velocity approaches ...

This program demonstrates how to draw lines in a picture box using the GDI, controlling background color and line color. It also includes a simple animation using a timer.

The future satellite communication systems are re- quired to support the higher transmission data rate for providing the multimedia services by employing the e铿僣ient modulation method such as multi-level QAM.

A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is convex if and only if, for any two points A and B inside the polygon, the line segment AB is inside P. One way to visualize a convex hull is to put a "rubber band" around all the points, and let it wr ...

ecos RTOS 原理介绍和应用开发The design philosophy of eCos was to augment an open-source RTOS (which meant no per-unit royalties) with source-level con?guration tools that would enable embedded developers to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu- all ...

this book mainly includes these contents :linked list, stacks and queuse, recursions, binary tree, multi tree, graphs, sorting, hashing, data compression.

Migma intends to help teachers to get several different multiple-choice exams based on the user?s original. This command line program quickly generates a number of different new tests (and their respective answer sheets
