In this paper we describe a control methodology for
catching a fast moving object with a robot manipulator,
where visual information is employed to track the
trajectory of the target. Sensing, planning and control
are performed in real-time to cope with possible
unpredictable trajectory Changes of the moving target,
and prediction techniques are adopted to compensate the
time delays introduced by visual processing and by the
robot controller. A simple but reliable model of the
robot controller has been taken into account in the
control architecture for improving the performance of the
system. Experimental results have shown that the robot
system is capable of tracking and catching an object
moving on a plane at velocities of up to 700 mm/s and
accelerations of up to 1500 mm/s2.
Given Perl s natural fit for web applications development, it s no surprise that Perl is also a natural choice for web services development. It s the most popular web programming language, with strong implementations of both SOAP and XML-RPC, the leading ways to distribute applications using web services. But books on web services focus on writing these applications in Java or Visual Basic, leaving Perl programmers with few resources to get them started. "Programming Web Services with Perl" Changes that, bringing Perl users all the information they need to create web services using their favorite language.
不錯的 PERL 教程
Find a Perl programmer, and you ll find a copy of Perl Cookbook nearby. Perl Cookbook is a comprehensive collection of problems, solutions, and practical examples for anyone programming in Perl. The book contains hundreds of rigorously reviewed Perl "recipes" and thousands of examples ranging from brief one-liners to complete applications. The second edition of Perl Cookbook has been fully updated for Perl 5.8, with extensive Changes for Unicode support, I/O layers, mod_perl, and new technologies that have emerged since the previous edition of the book. Recipes have been updated to include the latest modules. New recipes have been added to every chapter of the book, and some chapters have almost doubled in size.
DDR SDRAM控制器的VHDL源代碼，含詳細設計文檔。
The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS),
and Digital Frequency Synthesis (DFS) functions. This application note describes a controller
design for a 16-bit DDR SDRAM. The application note and reference design are enhanced
versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz,
16-bit data Changes at both clock edges. The reference design is fully synthesizable and
achieves 133 MHz performance with automatic place and route tools.
Introduction
Computer security is undeniably important, and as new vulnerabilities are discovered and
exploited, the perceived need for new security solutions grows. "Trusted computing"
initiatives propose to solve some of today s security problems through hardware Changes
to the personal computer. Changing hardware design isn t inherently suspicious, but the
leading trusted computing proposals have a high cost: they provide security to users
while giving third parties the power to enforce policies on users computers against the
users wishes -- they let others pressure you to hand some control over your PC to
someone else. This is a "feature" ready-made for abuse by software authors who want to
anticompetitively choke off rival software.
It needn t be this way: a straightforward change to the plans of trusted computing vendors
could leave the security benefits intact while ensuring that a PC owner s
This document provides guidelines and describes how to easily port S60 2nd Edition
C++ applications to S60 3rd Edition. The document has been written based on
experiences of porting regular S60 2nd Edition applications, such as the S60 Platform:
POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from
the example are shown in Chapter 8, “Application build Changes,” and in Appendix A,
“Code example." In addition, Appendix B, "Commonly used functions that require
capabilities," and Appendix C, "Commonly used interfaces that have been changed or
removed," provide useful information on some frequently used functions and interfaces
in third-party applications.

This file contains board-specific information for the Motorola cpv3060
target board. Specifically, this file contains information on any BSP
interface Changes from previous software or hardware versions, and
contains caveats that the user must be aware of before using this BSP.
Additionally, the target board s reference entry (i.e., cpv3060/target.nr)
provides board-specific information necessary to run VxWorks, and
should be read before this BSP is used.
This file contains board-specific information for the Motorola LoPEC in
support of the lopec BSP. Specifically, this file contains information on
any BSP interface Changes from previous software or hardware versions, and
contains caveats that the user must be aware of before using this BSP.
Additionally, the target board s manual page entry (for example,
lopec/target.nr) provides board-specific information necessary to run
VxWorks, and should be read before this BSP is used.
