三維矢量有限元-矩量法電磁場分析程序。
EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite ELEMENT method (VFEM). It employs the finite ELEMENT method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.
This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmitter. The fractional-N synthesizer forming the basis of the transmitter uses a combined phasefrequency
detector (PFD) and digital-to-analog converter (DAC) circuit ELEMENT to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.
/*
* The internal form of a hash table.
*
* The table is an array indexed by the hash of the key collisions
* are resolved by hanging a linked list of hash entries off each
* ELEMENT of the array. Although this is a really simple design it
* isn t too bad given that pools have a low allocation overhead.

Parses UK Profile 1.05/1.06 Object Carousel and saves files to disk (all
stored under /tmp/cache at the moment). The files are the scripts and
text/image data for MHEG5, the interactive(ish) ELEMENT of digital TV. At
the moment the MHEG scripts are not parsed, so to duplicate that
interactive experience, speedy usage of "cat" and "xv" is recommended.
Circular Convolution of two equal-length vectors. Highlights that circular convolution in the time domain is the effectively the same as ELEMENT-by-ELEMENT multiplication in the frequency domain.
非線性有限元程序，NONSAP is a general finite ELEMENT program for the nonlinear static and dynamic analysis of complex structures. The program is very flexible and was designed to be extended and modified by the user. In particular the program can easily be modified to use a different formulation of the equations of motions, different time integration operators and other additional options.
C 開發的有限元軟件，界面還可以，不錯，可以試試。 FElt is a free system for introductory level finite ELEMENT analysis. It is
primarily intended as a teaching tool for introductory type courses in finite
ELEMENTs - probably in the mechanical/structural/civil fields. In a command
line environment, FElt uses an intuitive, straightforward input syntax to
describe problems. It also includes a graphical user interface for
workstations that allows the user to set-up, solve and post-process the
problem in a single CAD-like environment.
Many CAD users dismiss schematic capture as a necessary evil in the process of creating
PCB layout but we have always disputed this point of view. With PCB layout now offering
automation of both component placement and track routing, getting the design into the
computer can often be the most time consuming ELEMENT of the exercise. And if you use
circuit simulation to develop your ideas, you are going to spend even more time working on
the schematic.
Need to make sense of the many changes to Visual Basic for the new .NET platform? VB .NET
Language in a Nutshell introduces the important aspects of the language and explains the .NET
framework. An alphabetical reference covers the functions, statements, directives, objects, and object
members that make up the VB .NET language. To ease the transition, each language ELEMENT
includes a "VB .NET/VB 6 Differences" section.
