Pulpwood refers to timber grown with the principal purpose of making wood pulp for paper production. However, pulpwood is also used as the raw material for some wood products, such as oriented strand board (OSB), and there is an increasing demand for pulpwood as a source of 'green energy' by the bio-energy sector. Trees raised specifically for pulp production account for 16% of world pulp production, old growth forests 9% and second- and third- and more generation forests account for the balance. Reforestation is practiced in most areas, so trees are a renewable resource. In the logging of mixed forest stands,...

Pulse dialing, dial pulse, or loop disconnect dialing, also called rotary or decadic dialling in the United Kingdom (because up to 10 pulses are sent), is pulsing in which a direct-current pulse train is produced by interrupting a steady signal according to a fixed or formatted code for each digit and at a standard pulse repetition rate. Dial pulsing originated with a rotary dial integrated into telephone instruments, for the purpose of signaling. Subsequent applications use electromechanical or electronic circuits to generate dial pulses. The pulses are generated through the making and breaking of the telephone...

Pulsed electric field (PEF) processing is a method for processing cells by means of brief pulses of a strong electric field. PEF holds potential as a type of low temperature alternative pasteurization process for sterilizing food products. In PEF processing, a substance is placed between two electrodes, then the pulsed electric field is applied. The electric field enlarges the pores of the cell membranes which kills the cells and releases their contents. PEF for food processing is a developing technology still being researched. There have been limited industrial applications of PEF processing for pasteurizing...

A pulse detonation engine, or "PDE", is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave initiated by an ignition source. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of roughly Mach 5. An ideal PDE design can have a thermodynamic efficiency higher than other designs like turbojets and turbofans because a detonation wave rapidly compresses the mixture and adds heat at constant volume. Consequently, moving parts like...

High Quality Content by WIKIPEDIA articles! A pulse jet engine (or pulsejet) is a very simple type of jet engine in which combustion occurs in pulses. Pulsejet engines can be made with few or no moving parts, and are capable of running statically.Since they were first invented in the early 1900s, pulsejets have remained relatively obscure, and after their use in the Second World War German cruise missiles, a lot of propaganda and misinformation has been spread about pulsejet engines. Over the years this misinformation has even been assimilated by college-level engineering textbooks, perpetuating the cycle of misinformation. Данное издание не является оригинальным.

High Quality Content by WIKIPEDIA articles! Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a numeric (usually binary) code. PCM has been used in digital telephone systems and 1980s-era electronic musical keyboards. It is also the standard form for digital audio in computers and the compact disc "red book" format. It is also standard in digital video, for example, using ITU-R BT.601. Uncompressed PCM is not typically used for video in standard definition consumer applications such as DVD or DVR because the bit rate required is far too high. Данное издание не является...

High Quality Content by WIKIPEDIA articles! In digital telecommunication, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal suit better to the communication channel by limiting the effective bandwidth of the transmission. By filtering the transmitted pulses this way, the intersymbol interference caused by the channel can be kept in control. In RF communication, pulse shaping is essential for making the signal fit in its frequency band. Typically pulse shaping occurs after line coding, and before modulation.

The Pulse tube cryocooler is a developing technology that emerged largely in the early 1980's with a series of other innovations in the broader field of Thermoacoustics. In contrast with other cryocoolers (eg Stirling cryocooler and Gifford-McMahon cooler), this cryocooler can be made without moving parts in the low temperature part of the device. The lack of moving parts makes the cooler suitable for a wide variety of applications.Pulse tube cryocoolers have been used in industrial applications such as semiconductor fabrication and in military applications such as for the cooling of infrared sensors. Pulse tubes are also being developed for cooling of astronomical detectors where liquid cryogens are typically used, such as the Atacama...

Pulse-Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range-rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of RF energy returning from the target are processed to measure the frequency shift between carrier cycles in each pulse and the original transmitted frequency. To achieve this, the transmitter frequency source must have very good phase stability and the system is said to be coherent. The nature of pulsed radar, and the relationship between the carrier frequency and the...

Pulse compression is a signal processing technique mainly used in radar, sonar and echography to augment the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with the transmitted pulse. The simplest signal a pulse radar can transmit is a sinusoidal pulse of amplitude, scriptstyle A and carrier frequency, scriptstyle f_0, truncated by a rectangular function of width, scriptstyle T. Let us determine the range resolution which can be obtained with such a signal. The return signal, written scriptstyle r(t), is an...

This work is devoted to pulsed thermography (PT). The main research topic is reconstruction of defect shape from thermographic data. The data compression problem is also considered. The reconstruction of the defect shape from pulsed thermography data is an ill-posed inverse problem. The existing algorithms are applicable only for ideal defect cases. In this work a new defect shape reconstruction algorithm is proposed. The developed algorithm combines the principle of the thermal pulse reflection in the one-dimensional domain with the numerical simulation of the PT experiment. The algorithm can be applied for wide classes of defects. The experimental reconstruction of the corrosion profile in a steel sample by the developed algorithm is...

A Pulse Forming Network (PFN) accumulates electrical energy over a comparatively long time, then releases the stored energy in the form of a relatively square pulse of comparatively short duration for various pulsed power applications. In practice, a PFN is charged by means of a high voltage power source, then rapidly discharged into a load via a high voltage switch, such as a spark gap or hydrogen thyratron. The load may be a high power microwave oscillator such as a klystron or magnetron, a flash lamp, or even an electromagnet. Depending upon the application, the output pulse repetition rate may range from a...

High Quality Content by WIKIPEDIA articles! A pulse wave or pulse train is a kind of non-sinusoidal waveform that is similar to a square wave, but does not have the symmetrical shape associated with a perfect square wave. It is a term common to synthesizer programming, and is a typical waveform available on many synths. The exact shape of the wave is determined by the duty cycle of the oscillator. In many synthesizers, the duty cycle can be modulated for a more dynamic timbre. The pulse wave is also known as the rectangular wave, the periodic version of the rectangular function.

Pulse-density modulation, or PDM, is a form of modulation used to represent an analog signal with digital data. In a PDM signal, specific amplitude values are not encoded into pulses as they would be in PCM. Instead, it is the relative density of the pulses that corresponds to the analog signal's amplitude. Pulse-width modulation (PWM) is the special case of PDM where all the pulses corresponding to one sample are contiguous in the digital signal. A PDM bitstream is encoded from an analog signal through the process of delta-sigma modulation. This process uses a one bit quantizer that produces either a 1 or 0...

High Quality Content by WIKIPEDIA articles! A pump is a device used to move fluids, such as liquids or slurries, or gases. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps. Their names describe the method for moving a fluid. Данное издание не является оригинальным.

A pump-jet, hydrojet, or water jet, is a marine system that creates a jet of water for propulsion. The mechanical arrangement may be a ducted propeller with nozzle, or a centrifugal pump and nozzle. The first functioning man-made pump-jet engine was created by New Zealand inventor Sir William Hamilton in 1954. In the Ordovician period the first known cephalopods swam by a natural built-in reciprocating hydrojet. Pump jets have some advantages over bare propellers for certain applications, usually relate to requirements for high-speed or shallow-draft operations. These include: Increasing the speed before the...

Pump-action shotguns, also called 'slide action repeating shotguns' or 'slide action shotguns' are a class of shotguns that are distinguished in the way in which spent shells are extracted and fresh ones are chambered. The weapon has a single barrel above a tube magazine into which shells are inserted. New shells are chambered by pulling a pump handle (often called the fore-end) attached to the tube magazine toward the user, then pushing it back into place to chamber the cartridge (in a few cases this action is reversed). Fore-ends are replaceable, and modern ones may include a pistol grip for a more secure...

A pump-action rifle or shotgun is one in which the handgrip can be pumped back and forth in order to eject a spent round of ammunition and to chamber a fresh one. It is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger whilst reloading. When used in rifles, this action is also commonly called a slide action. The term pump-action can also be applied to various airsoft guns and air guns, which use a similar mechanism to both load a pellet and compress a spring piston for power, or pneumatic guns where a pump is used to...

Pumped storage hydroelectricity is a type of hydroelectric power generation used by some power plants for load balancing. The method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric power is used to run the pumps. During periods of high electrical demand, the stored water is released through turbines. Although the losses of the pumping process makes the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. Pumped storage is the largest-capacity form of grid energy storage now available. Данное издание не является...
