The HPBW is often referred to as the 3 dB beamwidth for obvious reasons. First null beamwidth (FNB W): The angle spanned by the main lobe. The FNBW is associated with the ability of an antenna to reject interference.

Imagine that you ve downloaded a package named foobar-1.0-1.i386.rpm and you re now ready to install it. In this example, foobar is the name of the package, 1.0-1 are version numbers, and i386 is the architecture (in this case Intel 386, meaning PC-type processors). You can install an RPM package from any directory, but it s best to keep the packages you ve downloaded in a central location. You can use an already existing directory, or you can create one just for this purpose. To install this file to a directory called /RPM, for example, give the su command to become root, and then give the following command:

ThreadCountLock.release() # Main function if __name__ == __main__ : # Open the URL-list file. Take the first command-line # argument, or just use the hard-coded name. if (len(sys.argv)>=2): URLFileName = sys.argv[1] else: URLFileName=URL_FILE_NAME try: URLFile = open(URLFileName) URLList = URLFile.readlines() URLFile.close() except: print Error reading URLs from: ,URLFileName sys.exit() # Create some worker threads, and start them running URLListLock = thread.allocate_lock() ThreadCountLock = thread.allocate_lock() # We acquire the MainThreadLock. The last worker thread to exit # releases the lock, so that we can acquire it again (and exit) MainThreadLock = thread.allocate_lock() MainThreadLock.acquire() WorkerThreadCount = 0 for X in range(0,WORKER_COUNT): NewThread = WorkerThread(URLList,URLListLock) thread.start_new_thread(NewThread.run,()) # This call will block until the last thread releases the main # thread lock in DecrementThreadCount().
