The measure of combat efficiency in an indecisive campaign is a matter of personal choice.

But it would greatly strengthen any Mayor's executive powers, remove the excuse in large degree that he is a captive of inaction in the Board of Estimate, increase his budget-making authority both as to expense and capital budgets, and vest in him the right to reorganize city departments in the interest of efficiency and economy.

The purpose of the organization is to further the interest of women students in recreational activities as a means of promoting physical efficiency, sportsmanship, and `` play for play's sake ''.

Thus technical efficiency is achieved at the expense of actual experience.

American policy should press constantly the view that until these governments demand efficiency and effectiveness of their bureaucracies there is not the slightest hope that they will either modernize of democratize their societies.

The luminous gain of a single stage with Af ( flux gain ) is, to a first approximation, given by the product of the photocathode sensitivity S ( amp / lumen ), the anode potential V ( volts ), and the phosphor conversion efficiency P ( lumen/watt ).

The luminous efficiency Af of a photocathode depends on the maximum radiant sensitivity Af and on the spectral distribution of the incident light Af by the relation: Af where Af is normalized radiant photocathode sensitivity.

The packing efficiency, F.R., of fiber plates did not receive much attention in the literature, probably as it is high for the larger fibers generally used, until rather recently.

For circular fibers in a closely packed hexagonal array, the packing efficiency is given by: Af where Af, and 0.906 is the ratio of the area of a circle to that of the circumscribed hexagon.

Thus, the efficiency **yt couplers is given by -- Af or approximately 50 percent each.

The efficiency Af of an Af lens at the magnification Af is: Af.

Thus, the combined efficiency of the elements replaced by the two fiber plates ( with a combined efficiency of 0.25 ) is 0.043 or about six times less than that of the two fiber plates.

`` Washington '', President Kennedy has been heard to remark ironically, `` is a city of southern efficiency and northern charm ''.

Each system develops differently, according to the area it serves, but the universal goal is to pool the resources of a given area for maximum efficiency.

Improved bandwidth efficiency is achieved at the expense of increased transmitter and receiver complexity by completely suppressing both the carrier and one of the sidebands.

Usually the efficiency or running time of an algorithm is stated as a function relating the input length to the number of steps ( time complexity ) or storage locations ( space complexity ).

Run-time efficiency is a topic of great interest in computer science: A program can take seconds, hours or even years to finish executing, depending on which algorithm it implements ( see also performance analysis, which is the analysis of an algorithm's run-time in practice ).

Technology is often a factor but so are military-social issues, the relationships between artillery and other arms, and the criteria by which military capability, efficiency and effectiveness are judged.

The speed at which they do so is a measure of market efficiency.

Drain efficiency is the ratio of output RF power to input DC power when primary input DC power has been fed to the drain of an FET.

Based on this definition, the drain efficiency cannot exceed 25 % for a class A amplifier that is supplied drain bias current through resistors ( because RF signal has its zero level at about 50 % of the input DC ).

The reason for this is that the loss of efficiency produces heat as a by-product of the energy lost during the conversion of power.

To light industry, the economies of being on one floor are much slighter, but efficiency engineers usually believe in them, and manufacturers looking for ways to cut costs cannot be prevented from turning to efficiency engineers.

Exact ( not asymptotic ) measures of efficiency can sometimes be computed but they usually require certain assumptions concerning the particular implementation of the algorithm, called model of computation.

Amplifiers of Class C-F are usually known to be very high efficiency amplifiers.

For medium spans, trusses or box beams are usually most economical, while in some cases, the appearance of the bridge may be more important than its cost efficiency.

Nominal X-ray energy is usually limited to 5 MeV ; the USA has provisions for up to 7. 5 MeV, which increases conversion efficiency.

The lubricant marketer claims improved equipment efficiency when compared to rival products or technologies, the claim is usually valid when comparing lubricant of higher specification with previous grade.

This disagreement usually takes the form of competing empirical tests of the elasticities of demand and supply in labor markets and the degree to which markets differ from the efficiency that models of perfect competition predict.

The objective of a turbocharger is to improve an engine's volumetric efficiency by increasing density of the intake gas ( usually air ).

Specific impulse ( usually abbreviated I < sub > sp </ sub >) is a way to describe the efficiency of rocket and jet engines.

Major modern highways that connect cities in populous developed and developing countries usually incorporate features intended to enhance the road's capacity, efficiency, and safety to various degrees.

Complete treatment usually lasts up to 3 weeks and involves making oneself sleep for only a minimum amount of time that they are actually capable of on average, and then, if capable ( i. e. when sleep efficiency improves ), slowly increasing this amount (~ 15 min ) by going to bed earlier as the body attempts to reset its internal sleep clock.

However, reciprocating engine generators are quicker to respond to changes in output power requirement and are usually slightly more efficient, although the efficiency of microturbines is increasing.

The loss of friction is usually only temporary and the material regains its efficiency when cooled, but if the surface overheats to the point where it becomes glazed the reduction in braking efficiency is more permanent.

" In heating and air conditioning ( HVAC ) applications, the term heat pump usually refers to easily reversible vapor-compression refrigeration devices that are optimized for high efficiency in both directions of thermal energy transfer.

Many social democrats and " New Deal liberals ", have adopted this analysis for public policy, so they view market failures as a very common problem of any unregulated market system and therefore argue for state intervention in the economy in order to ensure both efficiency and social justice ( usually interpreted in terms of limiting avoidable inequalities in wealth and income ).

Military science involves creation of theories, concepts, methods and systems applicable to the functions and activities of the armed forces, usually undertaken to increase overall military capability by increasing efficiency, effectiveness and simplicity of complex concepts, methods and systems used in military operations in peace during a war.

The activators can undergo change of valence ( usually oxidation ), the crystal lattice degrades, atoms – often the activators – diffuse through the material, the surface undergoes chemical reactions with the environment with consequent loss of efficiency or buildup of a layer absorbing either the exciting or the radiated energy, etc.

Many modern designs are asymmetrical, usually having the widest beam slightly farther aft which improves efficiency and promotes more level fore and aft trim.

Particularly with small run-of-the-river plants, the flat efficiency curve yields better annual performance than other turbine systems, as small rivers ' water is usually lower in some months.

In practical applications, other factors are usually highly significant in determining the fuel efficiency of a particular engine design in that particular application.

The trade-off for high efficiency at reasonable cost is usually relatively low excursion capability ( i. e., inability to move " in and out " as far as many home woofers can ), as they are intended for horn or large reflex enclosures.
