In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, though certain applications use alternative waveforms, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current.

In most instances, the weight reverses direction and then returns to (almost) the same position as the original release location — i.e. a small distance from the volunteer's face — thus leaving the volunteer unharmed. On occasion the volunteer is injured if either the volunteer does not stand still or the pendulum is initially released with a push (so that when it returns it surpasses the release position).

When a hot fluid flows through the cell, heat from the fluid is transferred to the cell wells, and stored there. When the fluid flow reverses direction, heat is transferred from the cell walls back to the fluid. A third type of regenerator is called a "Rothemuhle" regenerator. This type has a fixed matrix in a disk shape, and streams of fluid are ducted through rotating hoods.

It can be heard from the railway couplings when a train reverses direction. Another example is in a valve train with mechanical tappets, where a certain range of lash is necessary for the valves to work properly. Backlash Depending on the application, backlash may or may not be desirable. Some amount of backlash is unavoidable in nearly all reversing mechanical couplings, although its effects can be negated or compensated for.

While this is a reversal potential in the sense that membrane potential reverses direction, it is not an equilibrium potential because not all (and in some cases, none) of the ions are in equilibrium and thus have net fluxes across the membrane. When a cell has significant permeabilities to more than one ion, the cell potential can be calculated from the Goldman–Hodgkin–Katz equation rather than the Nernst equation.

These terms refer to how the current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative. If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes the form of a sine wave.

The momentum of the pendulum continues to move the second pallet toward the wheel, pushing the escape wheel backward for a distance, until the pendulum reverses direction and the pallet begins to move away from the wheel, with the tooth sliding along its surface, pushing it. Then the tooth slides off the end of the pallet, beginning the cycle again. Neither the anchor escapement nor the deadbeat form, below, are self-starting. The pendulum must be given a swing to get them going.

52, as quoted by G.J. Whitrow, The Natural Philosophy of Time (New York: Harper Torchbooks, 1961), p. 215. In 1911, Paul Langevin gave a "striking example" by describing the story of a traveler making a trip at a Lorentz factor of (99.995% the speed of light). The traveler remains in a projectile for one year of his time, and then reverses direction. Upon return, the traveler will find that he has aged two years, while 200 years have passed on Earth.

Generally, anything in an autoclave that happens suddenly ends up being very bad news. One can be placed at the inlet to the circulation fan; this one senses the lowest temperature, assuming that the heater is downstream of the fan.This is not always the case, since placing the fan downstream of the heater results in better mixing of the heated and unheated air. Another can be placed at the point at which the airflow reverses direction and begins to flow past the workload.

The cyclone geometry, together with volumetric flow rate, defines the cut point of the cyclone. This is the size of particle that will be removed from the stream with a 50% efficiency. Particles larger than the cut point will be removed with a greater efficiency, and smaller particles with a lower efficiency as they separate with more difficulty or can be subject to re-entrainment when the air vortex reverses direction to move in direction of the outlet. Airflow diagram for Aerodyne cyclone in standard vertical position.

In fact, in an RFP the externally applied toroidal field is switched off shortly after startup. The plasma in an RFP is also much closer to the wall than in a Tokamak. This permits a peculiar arrangement of the magnetic field lines, which will 'relax' into a new state such that the total magnetic energy in the plasma is minimized and the total magnetic helicity is conserved. The relaxed state, called a Taylor state, is marked by a peculiar arrangement of magnetic field lines where the toroidal magnetic field at the edge spontaneously reverses direction.

Alternating current (green curve). The horizontal axis measures time (it also represents zero voltage/current) ; the vertical, current or voltage. Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket.

Its primary diet includes grass and weed seeds, caterpillars, grasshoppers, and crickets, but it may also eat mice and shrews; it will viciously attack and consume cicadas if able to catch them. This squirrel sometimes damages gardens by digging burrows and eating vegetables, but also devours weed seeds and harmful insects. It is well known for standing upright to survey its domain, diving down into its burrow when it senses danger, then sometimes poking out its nose and giving a bird-like trill. It has a maximum running speed of and reverses direction if chased.

Lake Ahémé is Benin's second largest lake, with an area of in the dry season which expands to in the rainy season. The lake is long and has an average width of . The Couffo River drains into the swampy north end of the lake, while the 10 km-long Aho Channel connects the lake's southern end to the Grand-Popo Lagoon on the Atlantic coast. This channel flows south during the wet season but reverses direction in the dry season, which causes the salinity of the lake's southern end to increase.

A wave comes out of the guitar, and aside from Juanes, everyone through whom the wave passes is frozen in time, performing the same motion repeatedly in forward and reverse. During the last chorus, the wave reverses direction, and the people of the town disappear. The waves emitted by the guitar are sucked back in to the guitar. It is unexplained the identity of the women and the old man, and their motives, but it is assumed that they are sinister and possibly they are not even humans.

A head fake is a type of feint in which someone moves the head to fake an intended change in direction and thereby deceive opponents. The term originated in sports, but it has become applied more broadly. In financial markets, a head fake refers to a time when the market appears to be moving in one direction, but ends up moving in the opposite direction. For example, the price of a stock may appear to move up, and all indications prior to that are that it will move up, but shortly afterward, it reverses direction and starts moving down.

1984, , p.103, the outlet area of a compressor is significantly smaller than that of its inlet, which is fine when operating at the design pressure ratio, but during starting and at low throttle settings the compressor pressure ratio is low so ideally the outlet area should be much larger than its design value. Put crudely the air taken in at the front cannot get out the back, which causes the blades at the front of the compressor to stall and vibrate. The compressor surges, which normally means the airflow reverses direction, causing a sharp drop in thrust.

The Indian Ocean gyre The Indian Ocean gyre, located in the Indian Ocean, is one of the five major oceanic gyres, large systems of rotating ocean currents, which together form the backbone of the global conveyor belt. The Indian Ocean gyre is composed of two major currents: the South Equatorial Current, and the West Australian Current. Normally moving counter-clockwise, in the winter the Indian Ocean gyre reverses direction due to the seasonal winds of the South Asian Monsoon. In the summer, the land is warmer than the ocean, so surface winds blow from the ocean to the land.

Arcade original The player no longer takes the role of the "Bug Blaster" from Centipede, but instead takes the role of an elf called the "Archer". The object of the game is to destroy a millipede that advances downward from the top of the screen. The millipede travels horizontally until it either hits an obstacle or reaches the edge of the screen, after which it drops one row and reverses direction. Once it enters the player's gray maneuvering area, it stays there and extra heads appear at intervals until both they and the millipede are destroyed.

Secondly, since the klystron has beam current throughout the RF cycle, it can only operate as an inefficient class-A amplifier, while the grid of the IOT allows more versatile operating modes. The grid can be biased so the beam current can be cut off during part of the cycle, enabling it to operate in the more efficient class B or AB mode. The highest frequency achievable in an IOT is limited by the grid-to-cathode spacing. The electrons must be accelerated off the cathode and pass the grid before the RF electric field reverses direction.

In fact it merely confirms that bees do not engage in fixed-wing flight, and that their flight is explained by other mechanics, such as those used by helicopters. In 1996 it was shown that vortices created by many insects' wings helped to provide lift. High-speed cinematography and robotic mock-up of a bee wing Re: work of Dr. Michael H. Dickinson. showed that lift was generated by "the unconventional combination of short, choppy wing strokes, a rapid rotation of the wing as it flops over and reverses direction, and a very fast wing-beat frequency".

Ordinary electrical cables suffice to carry low frequency alternating current (AC), such as mains power, which reverses direction 100 to 120 times per second, and audio signals. However, they cannot be used to carry currents in the radio frequency range, above about 30 kHz, because the energy tends to radiate off the cable as radio waves, causing power losses. Radio frequency currents also tend to reflect from discontinuities in the cable such as connectors and joints, and travel back down the cable toward the source. These reflections act as bottlenecks, preventing the signal power from reaching the destination.

Denim under a microscope. Selvedge identifier visible in white at the interior of a pair of jeans Most denim made today is made on a shuttleless loom that produces bolts of fabric 60 inches or wider, but some denim is still woven on the traditional shuttle loom, which typically produces a bolt 30 inches wide. Shuttle-loom-woven denim is typically recognizable by its selvedge (or selvage), the edge of a fabric created as a continuous cross-yarn (the weft) reverses direction at the edge side of the shuttle loom. The selvedge is traditionally accentuated with warp threads of one or more contrasting colors, which can serve as an identifying mark.

An aerial tramway consists of one or two fixed cables (called track cables), one loop of cable (called a haulage rope), and one or two passenger or cargo cabins. The fixed cables provide support for the cabins while the haulage rope, by means of a grip, is solidly connected to the truck (the wheel set that rolls on the track cables). An electric motor drives the haulage rope which provides propulsion. Aerial tramways are constructed as reversible systems; vehicles shuttling back and forth between two end terminals and propelled by a cable loop which stops and reverses direction when the cabins arrive at the end stations.

The force on the mass is equal to the vector sum of the spring force and the kinetic frictional force. When the velocity changes sign (at the maximum and minimum displacements), the magnitude of the force on the mass changes by twice the magnitude of the frictional force, because the spring force is continuous and the frictional force reverses direction with velocity. The jump in acceleration equals the force on the mass divided by the mass. That is, each time the mass passes through a minimum or maximum displacement, the mass experiences a discontinuous acceleration, and the jerk contains a Dirac delta until the mass stops.

The current now flows in the opposite direction, opposing the difference between the admitted flux \Phi_0 and the external field of just over \Phi_0/2. The current decreases as the external field is increased, is zero when the flux is exactly \Phi_0, and again reverses direction as the external field is further increased. Thus, the current changes direction periodically, every time the flux increases by additional half-integer multiple of \Phi_0, with a change at maximum amperage every half-plus-integer multiple of \Phi_0 and at zero amps every integer multiple. If the input current is more than I_c, then the SQUID always operates in the resistive mode.

The terms anode and cathode are not defined by the voltage polarity of electrodes but the direction of current through the electrode. An anode is an electrode through which conventional current (positive charge) flows into the device from the external circuit, while a cathode is an electrode through which conventional current flows out of the device. If the current through the electrodes reverses direction, as occurs for example in a rechargeable battery when it is being charged, the naming of the electrodes as anode and cathode is reversed. Conventional current depends not only on the direction the charge carriers move, but also the carriers' electric charge.

The first proposed explanation, called the 'motion extrapolation' hypothesis, is that the visual system extrapolates the position of moving objects but not flashing objects when accounting for neural delays (i.e., the lag time between the retinal image and the observer's perception of the flashing object). The second proposed explanation by David Eagleman and Sejnowski, called the 'latency difference' hypothesis, is that the visual system processes moving objects at a faster rate than flashed objects. In the attempt to disprove the first hypothesis, David Eagleman conducted an experiment in which the moving ring suddenly reverses direction to spin in the other way as the flashed object briefly appears.

The journey goes well initially, but soon the crew is terrorized by loud and jarring music that appears to come out of nowhere. Daryl brutally murders his sister Erin over a petty argument and flees; Teddy and Cy locate and subdue him, and return him to the group. Now calm, he explains to Teddy that "the land is like liquid" and declares that he and Erin managed to determine the coordinates of the end of the road: the source of the music. Ultimately the crew reverses direction, battered by deafening feedback, but discover Erin's body dressed like a scarecrow, propped up in a grotesque diorama, and a massive deadfall which Teddy attempts to climb.

As in most such experiments the MST plasma is a toroidal pinch, which means the plasma is shaped like a donut and confined by a magnetic field generated by a large current flowing through it. MST falls into an unconventional class of machine called a reversed field pinch (RFP.) The RFP is so named because the toroidal magnetic field that permeates the plasma spontaneously reverses direction near the edge. A reversed field pinch is formed similarly to other toroidal pinch devices, by driving current through the plasma from an associated capacitor bank or other high-current power source. In a tokamak the toroidal field is much stronger than the poloidal field, but in an RFP it's just the opposite.

Consequently, currents flowing along parallel paths on opposite faces of each conductor (on the air-side and on the substrate-side) are subject to the same inductance, and the overall current tends to be divided equally between the two faces. Conversely, the substrate does affect the electric field, so that the substrate side contributes a larger capacitance across the slots than does the air side. Electric charge can accumulate or be depleted more readily on the substrate face of the conductors than on the air face. As a result, at those points on the wave where the current reverses direction, charge will spill over the edges of the metalization between the air face and the substrate face.

On executing this scheme, however, they find a seemingly bottomless pit beyond the impeding rock and are swept into it as the sea rushes down the huge open gap. After spending hours descending at breakneck speed, their raft reverses direction and rises inside a volcanic chimney that ultimately spews them into the open air. When they regain consciousness, they learn that they've been ejected from Stromboli, a volcanic island located off Sicily. The trio returns to Germany, where Axel and Lidenbrock deduce that the electric storm at sea had reversed the poles of their compass — in actuality they hadn't been driven backward but forward to a new shore notable for containing gigantic hominids.

The Lettera 32 is a downstrike typebars typewriter. The typebars strike a red/black inked ribbon, which is positioned between the typebar and the paper by a lever whenever a key is pressed; a small switch located near the upper right side of the keyboard can be used to control the strike position of the ribbon, in order to print with black, red, or no ink (for mimeograph stencils). Ribbon movement, which also occurs at every keypress, automatically reverses direction when there is no ribbon left on the feed reel; two mechanical sensors, situated next to each wheel, move when the ribbon is put under tension (indicating ribbon end), attaching the appropriate wheel to the ribbon transport mechanism and detaching the other.

Its waters' flow reverses direction every year, caused by greatly varying amounts of water carried by the Mekong over the course of a year and the impact of monsoonal rains, that coincides with the river's maximum. The plains of the Mekong and Tonle Sap basin are confined in the North by the Dangrek and Central Annamite Mountains, and to the South by the Cardamom Mountains and Elephant Mountains. The plains completely surround the Tonle Sap Lake in the western half of the country and wind their way through the middle of the country following the course of the Mekong River. The two basins actually form a single body of water, the whole of which effects about 75% of Cambodia’s land cover.

In a four-cylinder engine, only one piston is on a power stroke at any given time. Each piston comes to a complete stop and reverses direction before the next one starts its power stroke, which results in a gap between power strokes and annoying harshness, especially at lower engine speeds (RPM). In a six-cylinder engine with an even firing interval, the next piston starts its power stroke 60° before the previous one finishes, which results in smoother delivery of power to the flywheel. Comparing engines on a dynamometer, a V6 engine shows instantaneous torque peaks of 150% above mean torque and valleys of 125% below mean torque, with a small amount of negative torque (engine torque reversals) between power strokes.

A simple example is that the 4-fold periodicity of the Fourier transform – and the fact that two-fold Fourier transform reverses direction – can be interpreted by considering the Fourier transform as a 90° rotation in the associated time–frequency plane: 4 such rotations yield the identity, and 2 such rotations simply reverse direction (reflection through the origin). The practical motivation for time–frequency analysis is that classical Fourier analysis assumes that signals are infinite in time or periodic, while many signals in practice are of short duration, and change substantially over their duration. For example, traditional musical instruments do not produce infinite duration sinusoids, but instead begin with an attack, then gradually decay. This is poorly represented by traditional methods, which motivates time–frequency analysis.

The current IL2 will continue in the negative direction, in fact it never reverses direction. It can be seen from the diagram that a negative IL2 will add to the current IL1 to increase the current delivered to the load. Using Kirchhoff's Current Law, it can be shown that ID1 = IC1 \- IL2. It can then be concluded, that while S1 is off, power is delivered to the load from both L2 and L1. C1, however is being charged by L1 during this off cycle (as C2 by L1 and L2), and will in turn recharge L2 during the following on cycle. Figure 3: With S1 open current through L1 (green) and current through L2 (red) produce current through the load Because the potential (voltage) across capacitor C1 may reverse direction every cycle, a non-polarized capacitor should be used.

Another feature of this dynamo model is that the currents are AC rather than DC. Their direction, and thus the direction of the magnetic field they generate, alternates more or less periodically, changing amplitude and reversing direction, although still more or less aligned with the axis of rotation. The Sun's major component of magnetic field reverses direction every 11 years (so the period is about 22 years), resulting in a diminished magnitude of magnetic field near reversal time. During this dormancy, the sunspots activity is at maximum (because of the lack of magnetic braking on plasma) and, as a result, massive ejection of high energy plasma into the solar corona and interplanetary space takes place. Collisions of neighboring sunspots with oppositely directed magnetic fields result in the generation of strong electric fields near rapidly disappearing magnetic field regions.

The LOOK algorithm is the same as the SCAN algorithm in that it also honors requests on both sweep direction of the disk head, however, this algorithm "Looks" ahead to see if there are any requests pending in the direction of head movement. If no requests are pending in the direction of head movement, then the disk head traversal will be reversed to the opposite direction and requests on the other direction can be served. In LOOK scheduling, the arm goes only as far as final requests in each direction and then reverses direction without going all the way to the end. Consider an example, Given a disk with 200 cylinders (0-199), suppose we have 8 pending requests: 98, 183, 37, 122, 14, 124, 65, 67 and that the read/write head is currently at cylinder 53.

Because the equations governing the flow of current in wire antennas are identical to the telegrapher's equations, antenna segments can be modeled as two-way, single-conductor transmission lines. The antenna is broken into multiple line segments, each segment having approximately constant primary line parameters, and .Since voltage lost due to radiation is typically small compared to the voltages required due to the antenna's surge impedance, and since dry air is a very good insulator, the antenna is often modeled as lossless: The essential loss or gain of voltage due to transmission or reception is usually inserted post-hoc, after the transmission line solutions, although it can be modeled as a small value of at the expense of working with complex numbers. At the tip of the antenna, the transmission-line impedance is essentially infinite (equivalently, the admittance is almost zero) and after a brief "pile-up" at the tip, the wave reverses direction and flows back towards the feedpoint.

The Lettera 22 is an oblique frontstroke typebar typewriter. The typebars strike a red/black inked ribbon, which is positioned between the typebar and the paper by a lever whenever a key is pressed; a small switch located near the upper right side of the keyboard can be used to control the strike position of the ribbon, in order to print with black, red, or no ink (for mimeograph stencils). Ribbon movement, which also occurs at every keypress, automatically reverses direction when there is no ribbon left on the feed reel; two mechanical sensors, situated next to each wheel, move when the ribbon is put under tension (indicating ribbon end), attaching the appropriate wheel to the ribbon transport mechanism and detaching the other. The Lettera 22 uses a basket shift or segment shift (that is, the unit including the typebars moves up and down when shifting, as opposed to the carriage shift system).

Trepidation (from Lat. trepidus, "trepidatious"), in now-obsolete medieval theories of astronomy, refers to hypothetical oscillation in the precession of the equinoxes. The theory was popular from the 9th to the 16th centuries. The origin of the theory of trepidation comes from the Small Commentary to the Handy Tables written by Theon of Alexandria in the 4th century CE. In precession, the equinoxes appear to move slowly through the ecliptic, completing a revolution in approximately 25,800 years (according to modern astronomers). Theon states that certain (unnamed) ancient astrologers believed that the precession, rather than being a steady unending motion, instead reverses direction every 640 years.a fully quoted translation is found in Jones A., Ancient Rejection and Adoption of Ptolemy’s Frame of Reference for Longitudes in Ptolemy in Perspective, (ed) A. Jones, Springer, 2010, p. 11. The equinoxes, in this theory, move through the ecliptic at the rate of 1 degree in 80 years over a span of 8 degrees, after which they suddenly reverse direction and travel back over the same 8 degrees. Theon describes but did not endorse this theory.
