With de Broglie's suggestion of the existence of electron matter waves in 1924, and for a short time before the full 1926 Schrödinger equation treatment of hydrogen like atom, a Bohr electron " wavelength " could be seen to be a function of its momentum, and thus a Bohr orbiting electron was seen to orbit in a circle at a multiple of its half-wavelength ( this historically incorrect Bohr model is still occasionally taught to students ).

The Bohr model for a short time could be seen as a classical model with an additional constraint provided by the ' wavelength ' argument.

A model of computation may be defined in terms of an abstract computer, e. g., Turing machine, and / or by postulating that certain operations are executed in unit time.

This idea has been considered in detail back in time to extreme densities and temperatures, and large particle accelerators have been built to experiment in such conditions, resulting in further development of the model.

Ten years later, Alexander Friedmann, a Russian cosmologist and mathematician, derived the Friedmann equations from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time.

In this model the Universe is roughly the same at any point in time.

A technique called bootstrapping the simulation model is used, which bootstraps initial data points using a pseudorandom number generator to schedule an initial set of pending events, which schedule additional events, and with time, the distribution of event times approaches its steady state — the bootstrapping behavior is overwhelmed by steady-state behavior.

The Urban Land Institute ( ULI ) awarded the Battery Park City Master Plan its 2010 Heritage Award, for having " facilitated the private development of 9. 3 million square feet of commercial space, 7. 2 million square feet of residential space, and nearly 36 acres of open space in lower Manhattan, becoming a model for successful large-scale planning efforts and marking a positive shift away from the urban renewal mindset of the time.

In this model, the universe is roughly the same at any point in time.

Since that time, the dominant paradigm in the area has been the information processing model of cognition that Broadbent put forward.

A more accurate description of how the temperature near the car varies over time would require an accurate model of how the temperature varies at different altitudes.

According to this model, an autonomous lexical item in a particular context loses the properties of a fully independent word over time and acquires the properties of a morphological affix ( prefix, suffix, infix, etc .).

A 2004 case study concluded that the proper use of screenshots can significantly support a user ’ s “ developing a mental model of the program ” and help in “ identifying and locating window elements and objects .” This research concluded that screen shots allowed users to “ learn more, make fewer mistakes, and learn in a shorter time frame ,” which can certainly assist in increasing the time frame for full implementation of a CRM system with limited technical or human support.

The French period Ville Nouvelle ( New Town ) of Casablanca was designed by the French architect Henri Prost, and was a model of a new town at that time.

In 2001, Nissan marketed its D22 pick-up model in Japan with the name Datsun, this time however the use of the brand name was wholly restricted to this one specific model name.

The two main data models at this time were the hierarchical model, epitomized by IBM's IMS system, and the Codasyl model ( Network model ), implemented in a number of products such as IDMS.

A temporal database is a database with built-in time aspects, for example a temporal data model and a temporal version of Structured Query Language ( SQL ).

The above three-level database architecture also relates to and being motivated by the concept of data independence which has been described for long time as a desired database property and was one of the major initial driving forces of the Relational model.

At Augsburg, on August 10, 1893, Rudolf Diesel's prime model, a single iron cylinder with a flywheel at its base, ran on its own power for the first time.

They wrote " History, as Hegel said, moves upward in a spiral of negations ," and that " punctuated equilibria is a model for discontinuous tempos of change ( in ) the process of speciation and the deployment of species in geological time.

Exact solutions of great theoretical interest include the Gödel universe ( which opens up the intriguing possibility of time travel in curved spacetimes ), the Taub-NUT solution ( a model universe that is homogeneous, but anisotropic ), and Anti-de Sitter space ( which has recently come to prominence in the context of what is called the Maldacena conjecture ).

A geographical map projection of a region of the earth onto a small, plane surface is a model which can be used for many purposes such as planning travel.

File: Niels Bohr. jpg | Niels Bohr ( 1885-1962 ): used quantum mechanical model ( known as the Bohr model ) of the atom which theorized that electrons travel in discrete orbits around the nucleus, showed how electron energy levels are related to spectral lines, received the Nobel Prize in Physics in 1922.

Much of the travel overland on Great Inagua was by a swamp vehicle, a Land Rover fitted with over-large tyres that became the model for the " dragon " used in the story.

Technical forecasting of passenger travel usually involves an urban transportation planning model, requiring the estimation of trip generation ( how many trips for what purpose ), trip distribution ( destination choice, where is the traveler going ), mode choice ( what mode is being taken ), and route assignment ( which streets or routes are being used ).

Another possibility for travel would be wireless transmission of a person's brain model between computers on already inhabited locations.

In 1895, The Time Machine by H. G. Wells used time as an additional “ dimension ” in this sense, taking the four-dimensional model of classical physics and interpreting time as a space-like dimension in which humans could travel with the right equipment.

To illustrate the point, an experiment to test for the mass of neutrinos or the decay of protons ( small departures from the model ) would be more likely to receive money than experiments to look for the violation of the conservation of momentum, or ways to engineer reverse time travel.

The basic A-1 model was the only one to be produced in any number, but developments included the B model with a custom armor-piercing warhead, and the C model with a conical warhead which was designed to hit the water short of the ship and then travel a short distance underwater to hit the ship below the waterline.

On the other hand, Euclidian optics provided a geometric model that was able to account for this, as well as the length of shadows and reflections in mirrors, because Euclid believed that the visual " rays " could only travel in straight lines ( something which is commonly accepted in modern science ).

The Time Tunnel's time travel model operates with the assumption that the past, the present, and the future are all alike continuing to exist in a manner to permit the random placement of a time traveler into any point of time.

), their household ( size, structure, relationships ), their vehicle ( age, make, model ) and a diary of their journeys on a given day ( their start and end location, start and end time, mode of travel, accompanyment and purpose of travel ).

2006 – Cast A 2006 is the first student tour to travel under the one-semester Up with People program model.

While the travel guide was not a new form ( Baedecker followed the model of English guide books instituted by John Murray ), Baedeker's innovation was to include specific details of transportation, accommodations, prices, and so forth.

A true grand tourer is a luxury high-performance vehicle intended for long-distance high-speed travel in both comfort and style ; just because a manufacturer appended some form of GT initials to its model designation as a marketing gambit does not make such a car a grand tourer.

Medical tourism differs from the traditional model of international medical travel where patients generally journey from less developed nations to major medical centers in highly developed countries for medical treatment that is unavailable in their own communities.

The overworld map is a 3D model, featuring a scaled-down version of the game's fictional world which the player navigates to travel between the game's locations.

President's Choice offers auto insurance and home insurance, underwritten through a broker model by a number of selected Canadian insurance companies, pet insurance, underwritten by SecuriCan General Insurance Company, and travel insurance by Travel Guard Canada as managing general underwriter and agent for American Home Assurance Company.

Dependent on the model the Fastrac can travel at 50 km / h, 65 km / h or 75 km / h ( 40 mph ).

Cheng admitted during his cross-examination that his findings were " probable, not precise "; tidal systems are sufficiently chaotic, and he was unable to develop an exact model of the bodies ' disposal and travel.

Eugene Parker was in attendance at this conference and developed scaling relations for this model during his return travel.
