A common shortcoming of these classification schemes is that they produce distinct boundaries between the zones they define, rather than the gradual transition of climate properties more common in nature.

The stationary points of the surface lead to predictions of different isomers and the transition structures for conversion between isomers, but these can be determined without a full knowledge of the complete surface.

When a transition between user mode and kernel mode is required in an operating system, a context switch is not necessary ; a mode transition is not by itself a context switch.

The Copper Age was originally defined as a transition between the Neolithic and the Bronze Age.

The transition from the European Copper Age to Bronze Age Europe occurs about the same time, between the late 5th and the late 3rd millennia BC.

This counter will increment once for every clock cycle and takes two clock cycles to overflow, so every cycle it will alternate between a transition from 0 to 1 and a transition from 1 to 0.

So the spacing, and the energy of a typical spectroscopic transition, between vibrational energy levels is about 100 times greater than that of a typical transition between rotational energy levels.

This lasted roughly between the establishment of Zaire in 1971, and the official beginning of the transition towards democracy, on 24 April 1990.

After the mega-deal, the Bucks had several seasons in transition, but most of these players would bear fruit.

The transition cost for smaller companies will be much lower because large companies will bear the initial cost of learning and smaller companies will not be required to reinvent the wheel.

Wildlife ranges from black bear, mountain lion, and mule deer in the mountain and transition zones to the kangaroo rat and the endangered desert tortoise on the valley floor.

On the other hand, managers and producers may progressively take more control of the artist, as happened, for instance, in Elvis Presley's swift transition in species from " The Hillbilly Cat " to " your teddy bear ".

With Haiti struggling through a democratic transition, the lesson that persistent, non-violent fighting for justice can bear fruit can be an inspiration for the whole country to work for a more stable and just future .”

The field, then, is ripe for new Southerners to step to the fore and write of this twentieth-century phenomenon, the Southern Yankeefication: the new urban economy, the city-dweller, the pains of transition, the labor problems ; ;

In still others which are barely on the threshold of the transition into modernity, the decade can bring significant progress in launching the slow process of developing their human resources and their basic services to the point where an expanded range of developmental activities is possible.

the other, is how to finance the transition.

The other problem is the matter of financing the transition period in the several cities and towns.

An analysis of the fiscal tax collection year calendars throughout the state indicates that transition may not be as painful as is commonly thought.

The purpose of the adjusted Federal share relating to the base allotment and of the transition provisions for reaching the unadjusted Federal share is to prevent dislocations from abrupt changes in matching rates.

It was recognized years ago that the transition from daytime to nighttime propagation conditions, and vice versa, is not an instantaneous process, but takes place over periods of time from roughly 2 hours before sunset until about 2 hours after sunset, and again from roughly 2 hours before sunrise until some 2 hours after sunrise.

This is exactly what happened in the transition from baroque to rococo music.

One of these is the `` dissolve '', which makes possible a visually smooth transition from scene to scene.

The transition from one state to the next is not necessarily deterministic ; some algorithms, known as randomized algorithms, incorporate random input.

There is a wide variety of representations possible and one can express a given Turing machine program as a sequence of machine tables ( see more at finite state machine, state transition table and control table ), as flowcharts ( see more at state diagram ), or as a form of rudimentary machine code or assembly code called " sets of quadruples " ( see more at Turing machine ).

Azerbaijan is an economy that has completed its post-Soviet transition into a major oil based economy ( with the completion of the Baku-Tbilisi-Ceyhan Pipeline ), from one where the state played the major role.

The government's policy toward conscientious objection is in transition, as part of Armenia's accession to the Council of Europe.

The atomic orbital concept is therefore a key concept for visualizing the excitation process associated with a given transition.

Amethyst is a purple variety of quartz ( SiO < sub > 2 </ sub >) and owes its violet color to irradiation, iron impurities ( in some cases in conjunction with transition element impurities ), and the presence of trace elements, which result in complex crystal lattice substitutions.

The color of amethyst has been demonstrated to result from substitution by irradiation of trivalent iron ( Fe < sup > 3 +</ sup >) for silicon in the structure, in the presence of trace elements of large ionic radius, and, to a certain extent, the amethyst color can naturally result from displacement of transition elements even if the iron concentration is low.

Still further south lies the Polar front, which is marked by a transition to very cold, relatively fresh, Antarctic Surface Water at the surface.

An electron from the 2s level fills in the 1s hole and the transition energy is imparted to a 2p electron which is emitted.

Finally, in 1740 the French astronomer Jacques Cassini, who is traditionally credited with the invention of year zero, completed the transition in his Tables astronomiques, simply labeling this year 0, which he placed at the end of Julian years labeled avant Jesus-Christ ( before Jesus Christ or BC ), and immediately before Julian years labeled après Jesus-Christ ( after Jesus Christ or AD ).

This amount of energy, i. e., wavelength, is specific to a particular electron transition in a particular element.

What is meant by stating that Aelbert learned form from his father is that his eventual transition from a specifically landscape painter to the involvement of foreground figures is attributed to his interaction with his Jacob.

The graphics are generated by a custom graphics chip called MARIA which is very different from other second and third generation consoles, and made it more difficult for game programmers to make the transition.
