The recovery will probably be sparked by a rising rate of housing starts next spring in response to more readily available mortgage credit, as well as by an expansion of Government spending, well sustained consumer spending, and some rebuilding of business inventories.

This means that the divergence measures the rate of expansion of a volume element as we let it

Data is collected concerning the rate of radial expansion of the cylinder and the maximum cylinder wall velocity.

Electrothermal-chemical ( ETC ) technology is an attempt to increase accuracy and muzzle energy of future tank, artillery, and close-in weapon system guns by improving the predictability and rate of expansion of propellants inside the barrel.

Ironically the rate of promotion of indigenous Fijian officers had been very rapid after the 1987 coup, and subsequent expansion of the Republic of Fiji Military Forces.

Cleaver said positive dark energy is currently responsible for speeding up the expansion rate of our universe as time moves on.

Tirpitz saw this once again as an opportunity to press for naval expansion and the continuation of the four capital ships per year building rate into 1912.

This provides maximum strength, an even bend and an even rate of expansion and contraction in water.

Children with reduced abilities to repeat nonwords ( a marker of speech repetition abilities ) show a slower rate of vocabulary expansion than children for whom this is easy.

Meditel's focus on lower-income markets impacted their average revenue per user, which fell by 16 %, but the resulting expansion of the customer base helped drive up the country's mobile penetration rate from 65. 7 % in 2007 to 74 % in 2008.

h is a parameter in the range reflecting the uncertainty in the value of the Hubble constant H for the rate of expansion of the universe: h = H / ( 100 km / s / Mpc ).

This is studied in chemical thermodynamics, which sets limits on quantities like how far a reaction can proceed, or how much energy can be converted into work in a combustion engine and which provides links between properties like the thermal expansion coefficient and change of rate in entropy with pressure for a gas or a liquid.

Cosmological redshift is seen due to the expansion of the universe, and sufficiently distant light sources ( generally more than a few million light years away ) show redshift corresponding to the rate of increase of their distance from Earth.

This economic expansion continued through the Clinton administration with unemployment rates steadily decreasing throughout his presidency ( 7. 3 % at the start of his presidency and 4. 2 % at the culmination, with the lowest rate reaching 3. 9 % in 2000 ).

The rate of this spatial expansion is accelerating, based on studies of Type Ia supernovae and corroborated by other data.

However, expansion of divided highways reduced the death rate.

Rapid industrialization and market expansion put Milan at the centre of Italy's leading industrial region, though in the 1890s Milan was shaken by the Bava-Beccaris massacre, a riot related to a high inflation rate.

Several factors are currently slowing the rate of global expansion of wheat production: population growth rates are falling while wheat yields continue to rise, and the better economic profitability of other crops such as soybeans and maize, linked with investment in modern genetic technologies, has promoted shifts to other crops.

When comparing the predicted expansion rate of the universe as given by the tracker solutions with cosmological data, a main feature of tracker solutions is that one needs four parameters to properly describe the behavior of their equation of state, whereas it has been shown that at most a two-parameter model can optimally be constrained by mid-term future data ( horizon 2015-2020 ).

If this type of energy were to exist, it would cause a big rip in the universe due to the growing energy density of dark energy which would cause the expansion of the universe to increase at a faster-than-exponential rate.

The rate of expansion and contraction of the quartz is the resonant frequency, and is determined by the cut and size of the crystal.

The small fall the unemployment rate, however, was achieved at the cost of a larger budget deficit ( which rose from 31. 2 billion DM to 75. 7 billion DM in 1981 ), brought about by fiscal expansion ).

Arguments have been raised, however, that the fall of the inflation rate may be less from control of the money supply and more to do with the unemployment level's effect on demand ; some also claim the use of credit to fuel economic expansion is itself an anti-monetarist tool, as it can be argued that an increase in money supply alone constitutes inflation.

Ben Bernanke, Princeton professor and current chairman of the US Federal Reserve, has argued that monetary policy could respond to zero interest rate conditions by direct expansion of the money supply.

Although widely attributed to Edwin Hubble, the law was first derived from the General Relativity equations by Georges Lemaître in a 1927 article where he proposed that the Universe is expanding and suggested an estimated value of the rate of expansion, now called the Hubble constant .< ref >

Dr. Bonnor supports the idea that the universe both expands and contracts, that in several billion years the expansion will slow up and reverse itself and that the contraction will set in.

This, he claims, would reasonably account for the expansion of the universe.

The graphic scheme above is an artist's concept illustrating the expansion of a portion of a flat universe.

In 1931 Lemaître went further and suggested that the evident expansion of the universe, if projected back in time, meant that the further in the past the smaller the universe was, until at some finite time in the past all the mass of the Universe was concentrated into a single point, a " primeval atom " where and when the fabric of time and space came into existence.

There were two primary explanations put forth for the expansion of the universe.

Cosmologists are still unable to explain all cosmological phenomena exactly on the basis of known conventional forms of energy, such as those related to the accelerating expansion of the universe.

Cosmologists therefore invoke a yet unexplored form of energy called dark energy ( dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe ) which account for certain cosmological observations mostly related to " accelerating expansion of Universe ".

Thus with the expansion of the universe, radiation becomes less dominant than matter.

The very early universe is said to have been ' radiation dominated ' and as such radiation controlled the deceleration of expansion.

As the expansion of the universe continues, matter dilutes even further and the cosmological constant becomes dominant, leading to an acceleration in the universe's expansion.

The solution is an expanding universe ; due to this expansion the radiation and matter in the universe are cooled down and become diluted.

At first, the expansion is slowed down by gravitation due to the radiation and matter content of the universe.

However, as these become diluted, the cosmological constant becomes more dominant and the expansion of the universe starts to accelerate rather than decelerate.

As a rule of thumb, a scattering or a decay process is cosmologically important in a certain cosmological epoch if the time scale describing that process is smaller or comparable to the time scale of the expansion of the universe, which is with being the Hubble constant at that time.

The case for dark energy was strengthened in 1999, when measurements demonstrated that the expansion of the universe has begun to gradually accelerate.

In physical cosmology, cosmic inflation, cosmological inflation or just inflation is the theorized extremely rapid exponential expansion of the early universe by a factor of at least 10 < sup > 78 </ sup > in volume, driven by a negative-pressure vacuum energy density.

As a direct consequence of this expansion, all of the observable universe originated in a small causally connected region.

Another adjunct, the varying speed of light model has also been theorized by Jean-Pierre Petit in 1988, John Moffat in 1992 as well Andreas Albrecht and João Magueijo in 1999, instead of superluminal expansion the speed of light was 60 orders of magnitude faster than its current value solving the horizon and homogeneity problems in the early universe.

Authors writing in the Lovecraftian milieu use elements of the Mythos in an ongoing expansion of the fictional universe.

Uniform cooling of the cosmic microwave background over billions of years is explainable only if the universe is experiencing a metric expansion.
