Fog

Fog is a complex atmospheric phenomenon. It is a visible mass consisting of cloud water droplets or ice crystals suspended in the air at or near the Earth's surface. Fog can be considered a type of low-lying cloud, and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog has affected many human activities, such as shipping, travel, and warfare.

Definition

The term "fog" is typically distinguished from the more generic term "cloud" in that fog is low-lying, and the moisture in the fog is often generated locally (such as from a nearby body of water, like a lake or the ocean, or from nearby moist ground or marshes).

By definition, fog reduces visibility to less than 1 kilometre (0.62 mi), whereas mist causes lesser impairment of visibility.

For aviation purposes in the UK, a visibility of less than 5 kilometres (3.1 mi) but greater than 999 metres (3,278 ft) is considered to be mist if the relative humidity is 70% or greater; below 70%, haze is reported.

Mist (novel)

Mist (Spanish: Niebla) is a nivola written by Miguel de Unamuno in 1907 and published in 1914. Unamuno scholars such as J.A.G. Ardila, have contended that Mist was inspired by the Danish philosopher Søren Kierkegaard's work Diary of a Seducer, a novella in Either/Or.

Plot summary

The plot revolves around the character of Augusto, a wealthy, intellectual and introverted young man. He falls in love with a young woman named Eugenia as she walks past him on the street, and he sets about trying to court her. He is aided in his efforts by the other members of Eugenia's household. Her aunt is particularly keen for a relationship to evolve, so that Augusto might help with her niece's financial troubles. Nevertheless, Eugenia rejects his advances, since she is already in a relationship with the down-and-out Mauricio. Augusto pays off Eugenia's mortgage as a goodwill gesture without her knowing, but this only serves to insult Eugenia, rather than endear her to him.

Tuman (album)

Tuman is a studio album of Sofia Rotaru released in the very beginning of 2007. The CD includes mostly unreleased, but already aired songs, although only a selection of them. It is a multilingual album, hence traditional edition for Sofia Rotaru. It includes popular duet with Nikolay Baskov "Raspberries Blossom" and dance remix of "White Dance", which marked in 2001 a new wave in the repertoire of Sofia Rotaru. The last song of the album "One Guelder Rose (or One Snowball Tree) was one of the most popular songs of Sofia Rotaru in Ukrainian for the last three years.

Swap (finance)

A swap is a derivative in which two counterparties exchange cash flows of one party's financial instrument for those of the other party's financial instrument. The benefits in question depend on the type of financial instruments involved. For example, in the case of a swap involving two bonds, the benefits in question can be the periodic interest (coupon) payments associated with such bonds. Specifically, two counterparties agree to exchange one stream of cash flows against another stream. These streams are called the legs of the swap. The swap agreement defines the dates when the cash flows are to be paid and the way they are accrued and calculated. Usually at the time when the contract is initiated, at least one of these series of cash flows is determined by an uncertain variable such as a floating interest rate, foreign exchange rate, equity price, or commodity price.

The cash flows are calculated over a notional principal amount. Contrary to a future, a forward or an option, the notional amount is usually not exchanged between counterparties. Consequently, swaps can be in cash or collateral.

Swap (computer science)

In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined thus (in pseudocode):

(In many programming languages where the swap function is built-in; in C++, overloads are provided allowing std::swap to swap some large structures in O(1) time.) After swap() is performed, x will contain the value 0 and y will contain 1; their values have been exchanged. Of course, this operation may be generalized to other types of values, such as strings, aggregated data types and comparison sorts, utilize swaps to change the positions of data.

Using a temporary variable

The simplest and probably most widely used method to swap two variables is to use a third temporary variable:

While this is conceptually simple and in many cases the only convenient way to swap two variables, it uses extra memory. Although this should not be a problem in most applications, the sizes of the values being swapped may be huge (which means the temporary variable may occupy a lot of memory as well), or the swap operation may need to be performed many times, as in sorting algorithms.
