zemax源码： This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.

his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

describes the most common terms used in radarsystems, such as range, range resolution, Doppler frequency, and coherency. The second part of this chapter develops the radar range equation in many of its forms. This presentation includes the low PRF, high PRF,search, bistatic radar, and radar equation with jamming.

Its a text-fading linking ticker type applet that will fade text of any color over any color background. It features rollover color feedback, and will pause when rolled over so the user doesn t have to "chase" links. It uses very little processor power and source is included! Now supports frames!

UWB 功率控制 容量 Main Matlab script is in runsim.m. It generates random topologies, optimizes, and display results. IMPORTANT: you may need to add manually the lib path in Matlab in order to get all the necessary functions. Reference: Radunovic, Le Boudec, "Joint Power Control, Scheduling and Routing in UWB networks"

Three-dimensional real-time graphics are a prevalent technology nowadays, thanks to the steady rise of processing power and specialized graphics hardware. One of the goals of computer graphics most sought after and difficult to achieve is to reproduce realistic outdoor environments featuring dense forests.

* This a software code module for a time-of-day clock object. * The clock may be fixed 12-hour, fixed 24-hour, or dynamically * configurable between these two types. Clock data can be accessed * as a binary number representing the number of minutes since midnight * or a BCD number formatted according to the time-of-day description * in the TIME module 0404x. The functions work with time-of-day values * which conform to normally accepted clock values of 1:00 to * 12:59 BCD / 0 to 719 binary for a 12-hour clock or clock values * 00:00 to 23:59 BCD / 0 to 1439 binary for a 24-hour clock. On power-up * the clock is 12:00 BCD / 0 binary for a 12-hour or dynamically * configurable clock, or 00:00 BCD / 0 binary for a 24-hour clock.

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.

This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other generic TCP/IP stacks today.
