Exempel på hur man kan använda POLARITY i en mening

• ); other categories relate to polarity, ionization, and side-chain group type (aliphatic, acyclic, aromatic, polar, etc.
• In B and C, the direction of the electrical and the magnetic fields are changed respectively which switches the polarity of the charges around.
• Lipscomb was intended to test the potential advantages of this propulsion system for providing quieter and safer operation for a full sized attack submarine (safer because reverse thrust would be instantaneous with reversal of the direct current engine's electric polarity).
• An improvement to Manchester coding which is a special case of binary phase-shift keying, it is not necessary to know the initial polarity of the transmitted message signal, because the information is not represented by the absolute voltage levels but by their transitions.
• In telecommunications, a neutral direct-current telegraph system (single-current system, single-current transmission system, single-Morse system) is a telegraph system in which (a) current flows during marking intervals and no current flows during spacing intervals for the transmission of signals over a line, and (b) the direction of current flow (electric polarity) is immaterial.
• It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom.
• The older machines are less efficient and exhibit an unpredictable tendency to switch their polarity, while the Wimshurst machine has neither defect.
• The effects of static electricity are familiar to most people because they can feel, hear, and even see sparks if the excess charge is neutralized when brought close to an electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative).
• This method utilizes fast Fourier transform (FFT) that converts amino acid sequences into a sequence composed of volume and polarity values for each amino acid residue.
• Hetero charge means that the polarity of the space charge is opposite to that of neighboring electrode, and homo charge is the reverse situation.
• A common misconception is that balanced audio requires the signal source to deliver equal waveforms of opposite polarity to the two signal conductors of the balanced line.
• Stereo broadcasting is made possible by using a subcarrier on FM radio stations, which takes the left channel and "subtracts" the right channel from it — essentially by hooking up the right-channel wires backward (reversing polarity) and then joining left and reversed-right.
• Another type of involution occurring in projective geometry is a polarity that is a correlation of period 2.
• Inverted polarity plugs can and do damage circuitry when plugged in, even if the voltage is correct; not all equipment is equipped with protection.
• Connectors are often keyed to ensure the correct polarity, and may contain bumps or notches both for polarity and to ensure that the wrong type of device is not inserted.
• When ordinary negative polarity cloud-ground lightning discharges into a grounding substrate, greater than 100 million volts (100 MV) of potential difference may be bridged.
• In 1926, Professor Motonori Matuyama of Kyoto University first proposed the theory of geomagnetic polarity reversal at Genbudo after discovering it had a reverse magnetization.
• Many multipliers only work in 2 quadrants (one input may only have one polarity), or single quadrant (inputs and outputs have only one polarity, usually all positive).
• The polarity of this Hall voltage indicates the type of material the sample is made of; if it is positive, the material is P-type, and if it is negative, the material is N-type.
• Titled "Project RS2", the game began as a sequel to Radiant Silvergun, and borrows many elements from it as well as the polarity mechanism from Treasure's Silhouette Mirage (1997).
