	Variation of the field - Wikipedia, the free encyclopedia
		In heraldry, variations of the field are any of a number of ways that a field (or a charge) may be covered with a pattern, rather than a flat tincture or a simple division of the field.
		The diminutives of the ordinaries are frequently employed to vary the field.
		Composed of pallets, the field is paly; of bendlets, bendy; in a bend-sinister-wise fashion (of skarpes, the diminutive in England of the bend sinister), bendy sinister; of chevronels, chevronny.

	Variable focus liquid crystal lens system - Patent 4190330
		Consequently, by varying this angle such as by tilting the crystal while keeping the direction of incident light fixed, a variation of refractive index is produced with respect to the extraordinary ray in the crystal.
		In such materials a variation in refractive index with respect to the extraordinary ray is effected by varying the angle between the directors relative to the direction of incoming light.
		To vary focal length, in such latter case, electric or magnetic fields may be used to tilt directors towards a direction parallel to the aligning layer.

	NPL Acoustics: Free-field response of electroacoustic transducers
		Determination of the variation in free-field response of electroacoustic transducers with temperature and depth
		Using the APV, the variation of the response of a transducer with temperature and depth may be determined.
		The measurements were undertaken with the test chamber at atmospheric pressure while the temperature of the water in the APV was varied to allow measurements to be made at five temperatures: 5 °C, 11 °C, 18 °C, 25 °C and 32 °C. Figure 2 shows the same data plotted against frequency.

	Aerospace Engineering Online: Studying aircraft lightning strikes
		An electrical discharge (positive leader) is initiated from the aircraft and propagates in the direction of the ambient field.
		The sign of these variations was different between sensors, indicating that this first phase corresponds to a variation of ambient field (leading to a polarization effect) rather than a variation of the aircraft net charge (as in the ab phase of triggered strikes).
		This could be attributed to the simultaneous inception of a positive and a negative leader, the latter injecting a higher charge in the aircraft, or even to the inception of a single negative stepped leader.

		They are known to have errors that are attributable to variation in the field and laboratory.
		Error variation in the field may follow trends linked to the spatial location of the plots.
		The key aspects are the use of a two-level experimental design, namely a valid field design and a subsequent re-randomisation of samples to ensure that the order of milling differs from field plot order.

	Applying Process Knowledge for Yield Variation Reduction: A Longitudinal Field Study* Decision Sciences - Find Articles
		The negative consequences of high yield variation in manufacturing settings are well known, yet the causes of yield variation are poorly understood (Lee & Yano, 1988;Spence, 1988; Avram& Wein, 1992; Bohn, 1995; Longtin, Wein, & Welsch, 1996; Zantek, Wright, & Plante, 2002).
		While much of this research has been motivated by the highly variable yields characteristic of the semiconductor industry, managers and engineers at our research site-an electromechanical motor assembly plant-agree that yield variation does create problems such as the ones mentioned earlier and needs to be addressed.
		Third, we identify both the type and sequence of actions that are effective in reducing yield variation-that is, applying process knowledge by way of actions to control the mean followed by actions to control the variance.

	Earth's Magnetic Field
		It does seem clear that the generation of the magnetic field is linked to the rotation of the earth, since Venus with a similar iron-core composition but a 243 Earth-day rotation period does not have a measurable magnetic field.
		It certainly seems plausible that it depends upon the rotation of the fluid metallic iron which makes up a large portion of the interior, and the rotating conductor model leads to the term "dynamo effect" or "geodynamo", evoking the image of an electric generator.
		The magnetic field of a current loop could sustain the magnetic dipole type magnetic field of the earth.

		The Zhoushan fishery field near the Changjiang estuary is one of import fishery resource areas in the East China Sea and play a significant role in the Chinese fishery resources.
		In the appropriate water temperature, the variations of the Zhoushan fishery field place was controlled by the high salinity linguiform front variation of Taiwan Warm Current, the center of the fishery field commonly located near the high salinity linguiform front of Taiwan Warm Current.
		The nutrient variation inputted by Changjiang River into fishery field was likely to be the important reason for the fishery field variation.1.

		Why does the field change its polarity at irregular intervals separated by intervals of order a million years.
		It has long been realized that the field must be due to electric currents flowing in the electrically conducting core.
		Becasue of the statistical indifference of the field to the sense of polarity it seems certain that these currents are driven by self-excited dynamo action.

	Agriculture applications - Crop Productivity/Within Field Variation
		An area of high biomass within a wheat field for example, may have lower backscatter or a higher backscatter relative to an area of lower biomass depending on the phenological stage of a crop and/or environmental conditions (including background soil moisture) at the time of image acquisition.
		For example, in a wheat field with high volumetric soil moisture, low biomass areas will have higher backscatter than the high biomass area.
		The three growth zones representing high to low biomass for the wheat fields were used as a mask to extract the H/ parameters of Cloude and Pottier.

		The normal expectation is for students to spend at least 25 hours in the schools during each long-term when taking one or more education courses.
		It is recognized that there will often be variation from the number of hours of field and laboratory experiences suggested for each course.

		Thought Field Therapy is a meridian-based treatment that facilitates rapid resolution of emotional distress.
		Thought Field Therapy (TFT) can be used to treat specific problems such as traumatic memories, phobias, stress, unresolved grief, sadness, worry, anger, headaches and other negative emotions, or it may be used as part of a more comprehensive on-going therapy.
		Alternatively, the Thought Field Therapist may instruct the client to use specific tapping sequences (called algorithms or recipes) to resolve specific issues.
