Sofia SIP is an open-source SIP User-Agent library, compliant with
the IETF RFC3261 specification. It can be used as a building block
for SIP client software for uses such as VoIP, IM, and many other
real-time and person-to-person communication services. The primary
target platform for Sofia SIP is GNU/Linux. Sofia SIP is based on a
SIP stack developed at the Nokia Research Center. Sofia SIP is
licensed under the LGPL.
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.
ARP test mode. According to the idea we design the arithmetic for the key part, first the system sends a message to the target machine, and then system wait for the response. Once system receives a message, it starts to analyze the message, according to the message s parameter system judges whether the message satisfies the conditions. Once the message satisfies all the conditions, the system thinks the machine is sniffing, and adds this machine into the list of sniffing machines. On this basis the detection has done well, and at the same time we insert the result into the log database for inquire and analyze later.
The code on this diskette has been organized by chapter. Each subdirectory
containing listing has a readme.txt describing program usage and any relevent
file formats. The readme will also describe how to compile the target
programs under IBM OS/2 (TM) using the using C Set++ compiler (TM). All programs on
this diskette have been compiled and tested in this environment. The majority
of programs on this diskette should port to other environments with only minor
adjustments. The exception to this are those programs which utilize
presentation manager for graphical display of program data. In particular,
the grid1 programs in \chapt4\backprop\ and \chapt3\ fall into this latter category.
