A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15.
Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand Back to 0.
Create a time protocol over Client/Server Environment by sending request about time to server from client and the server will response to give the correct time Back to the client.
This a two node test, requires a Coordinator
and an RFD. The coordinator and node simply
ping-pong a packet Back and forth, and print
out the RSSI byte. The RFD waits before
bouncing it Back, while the coordinator responds
immediately.
This manual describes omniidl, the omniORB IDL compiler. It is intended for developers
who wish to write their own IDL compiler Back-ends, or to modify existing
ones. It also documents the design of the compiler front-end for those poor souls
who have to track the IDL specification.
This a simple hardware UART test program. It receives text lines over
the serial port and writes Back a status msg with length and contents of
the buffer.
This simulation script set allows for an OFDM transmission to be
simulated. Imagetx.m generates the OFDM signal, saving it as a
windows WAV file. This allows the OFDM signal to be played out a sound
card and recorded Back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.
First of all, the Applet-phone is a SIP User-Agent
with audio and text messaging capabilities. But i s also embedded in
an applet where you can use it as usual if your firewall allow you to
use the UDP transport. If not, you can use TCP to carry your voice in a
voice messaging fashion. Your voice is recorded and encoded locally
then sent as a message, decoded and played Back by your peer. Voice
messaging allow you to go through any firewall, so that you can
continue to chat and talk with your friends from an applet !
