This book focuses only on PVRST+, and briefly at that. To enable PVRST+, use the following command:

The flags specified by flags are cleared. (All other flags are unaffected.) Sometimes it is useful to know the current flag settings. You can retrieve the current flag values by using the flags( ) function, whose prototype is shown here: fmtflags flags( ); This function returns the current value of the flags relative to the invoking stream.

bottom of the circle until it turns into an I-beam with a tiny A with a curved line underneath it. This is a sign that CorelDRAW has detected a shape on the page and that it rightly assumes you want to fit text along the path. You could use the Text | Fit Text To Path command in CorelDRAW to fit selected existing text to a selected existing object, but it s not necessary when you can work live here. Click an insertion point and then type any address and telephone number. The text flows along the path of the circle, as shown in the illustration below, but it s upside-down because you re fitting text to the bottom and not to the top of the circle, which is easy to fix in the following steps.

During the last few years, technological innovations in space communications have given rise to new orbits and totally new systems designs. Medium Earth Orbit (MEO) satellite networks have been proposed that will orbit at distances of about 8,000 miles. Signals transmitted from a MEO satellite travel a shorter distance, which translates to improved signal strength at the receiving end. This means that smaller, lighter receiving terminals can be used. Also, because the signal is traveling a shorter distance to and from the satellite, there is less transmission delay. Transmission delay is the time it takes for a signal to travel up to a satellite and back down to a receiving station. For real-time communications, the shorter the transmission delays, the better. For example, a GEO satellite requires .25 seconds for a round trip. A MEO satellite requires less than .1 seconds to complete the job. MEO operate in the 2 GHz and above frequency range.

As with analog modems, more than one method can be used to convey information via an optical fiber. Different methods that were developed for the modulation of information include intensity modulation, frequency-shift keying, phase-shift keying, and polarization modulation. Because of the short drive distance associated with the use of LEDs and the simplicity of intensity modulation, this technique is used by the transmitter section of an LED that receives an electrical signal for conversion to an optical signal. Under intensity modulation the light signal is turned on and off to represent binary values of 1 and 0. The modulated carrier is given by Es(t) where Es E0 E0m(t) cos (2 fst)

mobile device A portable computer in the form of a smart phone or personal digital assistant (PDA). mobile site A portable recovery center that can be delivered to almost any location in the world. monitoring The continuous or regular evaluation of a system or control to determine its operation or effectiveness. multistation access unit (MAU) A Token Ring network device used to connect stations to the network. multiprotocol label switching (MPLS) A packet-switched network technology that utilizes a variable-length packet. In an MPLS network, each packet has one or more labels affixed to it that contain information that helps MPLS routers make packet-forwarding decisions without examining the contents of the packet itself (for an IP address, for instance). N+1 The practice of employing one more than the minimum required number of systems so that in the event of a planned or unplanned outage of one of the systems, the other systems will continue functioning and provide service. This term usually applies to HVAC, UPS, and electric generators. See also heating, ventilation, and air conditioning (HVAC), uninterruptible power supply (UPS), and electric generator. natural disaster A disaster that occurs in the natural world with little or no assistance from mankind. See also disaster. near-field communications (NFC) A standard for extremely short-distance radio frequency data communications.

Also called schedule coordinator or scheduler. A person responsible for keeping track of the schedule and progress on a project. This is not always a leadership position.

nous services. Thus, asynchronous frames are transmitted only when bandwidth reserved for synchronous operations is not used. In comparison, synchronous frames can be transmitted at any time as long as the negotiated synchronous bandwidth allocation is not exceeded. The token holding time for a station is initialized with the value corresponding to the difference between the arrival of the token and the TTRT value. To transmit asynchronous frames, a station must have a token and the THT timer must not have expired.

Each clip contains two components the physical Clip AV stream data and a corresponding Clip Information file. There is also a playlist created for each recorded clip, containing a single playitem. When the content is being edited, and a virtual playlist is created, the physical stream data of a clip is not changed. Instead, the virtual playlist refers to the desired portion of each clip to allow seamless playback. In order to fully support the seam-

The new PLT systems and capabilities being developed have the potential to address one of the most important aspects in the future of telecommunications. For years, the local loop or last mile has been the bottleneck. The dream of the ubiquitous information superhighway connecting all residential customers to a high speed Internet has not been achieved. There are two main reasons for this
