	Efficiency factor - Wikipedia, the free encyclopedia
		Efficiency factor: In data communications, the ratio of (a) the time to transmit a text automatically at a specified modulation rate to (b) the time actually required to receive the same text at a specified maximum error rate.
		All of the communication facilities are assumed to be in the normal condition of adjustment and operation.
		Telegraph communications may have different temporal efficiency factors for the two directions of transmission.

	Wuppertal Institute - FACTOR FOUR FAQ
		The idea behind FACTOR FOUR is that natural resources can be used more efficiently in all domains of daily life, either by generating more products, services and quality of life from the available resources, or by using less resources to maintain the same standard.
		The factor "4" is not meant as a fixed numerical value.
		FACTOR FOUR is not an organisation of which you can become a member or for which you can donate.

	Evaluation of Efficiency Factor Models used in Strut-and-Tie Modeling of Nonflexural Members (Site not responding. Last check: 2007-11-06)
		The results show that the efficiency factor has only a week relationship with the concrete strength and that the more important parameter is the angle of the strut relative to the longitudinal axis of the member.
		Efficiency models based solely, or primarily, on the concrete strength are found to have a poor correlation with the data.
		Efficiency models that account for the angle of the strut and models based on the modified compression field theory are found to give the best correlation with the test results.

	Power Factor Correction technology and Calculations
		Power factor is the ratio between the KW and the KVA drawn by an electrical load where the KW is the actual load power and the KVA is the apparent load power.
		A poor power factor due to an inductive load can be improved by the addition of power factor correction, but, a poor power factor due to a distorted current waveform requires an change in equipment design or expensive harmonic filters to gain an appreciable improvement.
		The Power factor of the total current supplied to the distribution board is monitored by a controller which then switches capacitor banks In a fashion to maintain a power factor better than a preset limit.

	motorsanddrives.com - Amps, Watts, Power Factor & Efficiency
		In an energy efficient motor, the losses are reduced by using designs that employ better grades of material, more material and better designs, to minimize the various items that contribute to the losses in the motor.
		The most significant factor of all these is the watts requirement of the motor for the various load levels because it is the watts that will determine the operating cost of the motor, not the amperage.
		It is for this reasons that the blanket statement can be made, that increasing motor efficiency will reduce the kilowatt hour consumption and the power cost for all classes of power users, regardless of their particular rate structure or power factor situation.

	Back to Basics - The Basics of Power Factor and Efficiency
		As dictated by the rules of power factor and efficiency, the energy consumed by an appliance is always greater than the energy provided by it.
		Instead of a pure sine wave, current waveforms rich in harmonics tend to be flattened or peaked.
		Efficiency is the ratio of the energy output of an appliance to the energy input, expressed as a percentage.

	Water Science & Technology 43:8 (2001) 139-144 - M Han et al. - Collision efficiency factor of bubble and particle ...
		To determine the theoretically optimum particle size for any given bubble size, a collision efficiency diagram for DAF was developed where collision efficiency is contoured on a plane of particle and bubble sizes for different conditions of particle zeta potential.
		A set of experiments tested the validity of the suggested collision efficiency diagram, and examined whether pretreatment is important and why slight coagulant overdosing and shorter flocculation times are generally preferred in DAF, both current accepted practice.
		A collision efficiency diagram identifies the pretreatment goal, i.e., tailoring of the optimum characteristics required of particles (zeta potential and size) under existing operational bubble characteristic.

	Pozzolan Cementing Efficiency Factor (Site not responding. Last check: 2007-11-06)
		The Pozzolan Cementing Efficiency Factor is defined as the ratio of the cementing efficiency of Pozzolan to the cementing efficiency of the cement to which the Pozzolan is added.
		Since Pozzolans generally act as retarders, the Pozzolan cementing efficiency factor is usually negative for test ages of 7 days or less, since initially the strength of concrete containing Pozzolan is less than the strength of concrete which does not contain Pozzolan.
		The DOE Method recommends that concrete mixes, in which Pulverized Fuel Ash is the Pozzolan, should be designed on the basis of their strengths at 28 days but Firstmix allows the user to specify Pozzolan cementing efficiency factors for a range of test ages.

	Unionization and Cost of Production
		Clark (1984), in a later study of manufacturers, reports little difference in factor intensities between union and nonunion firms, which is still inconsistent with the prediction of a sharp decline in labor intensity, although less dramatic.
		From a competitive general-equilibrium perspective, allocative efficiency is attained at the point on the firm's demand curve corresponding to the competitive wage rate, where the contract and demand curves coincide.
		Work rules and employment restrictions have been widely examined for their effects on technical efficiency (shifts in the production technology), but efficient contracting, estimates of the effect on technical efficiency, and our analysis here suggest that the primary effect of these restrictions is instead on allocative efficiency (distortions from the least-cost combination of inputs).

	G5450 Wood Fuel for Heating, MU Extension
		To heat efficiently, combustible gases released during the burning process must be mixed with ample oxygen at a minimum temperature of 1,100 degrees.
		Because no heating unit performs at that efficiency, you need to know or estimate the relative efficiencies of the heating units you are considering or currently using.
		At those efficiencies, the cord of red oak would be equivalent to only (5,060,000 ÷ 70,000) 72.3 gallons of oil, which at 45 cents a gallon would give the cord of red oak a value of (72.3 x 0.45) $32.54.
