Delta Reticuli ( Delta Ret, δ Reticuli, δ Ret) is a star in the southern constellation of Reticulum. It is visible to the naked eye, having an apparent visual magnitude of 4.60. [2]
2001 Image of the active delta front before Hurricanes Katrina and Rita destroyed much of the delta in 2005. The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre (4,700 sq mi; 12,000 km 2) area of land that stretches from ...
The 1st Special Forces Operational Detachment–Delta ( 1st SFOD-D ), referred to as Delta Force, Combat Applications Group ( CAG ), Army Compartmented Elements ( ACE ), or within Joint Special Operations Command (JSOC), Task Force Green, [2] is a special operations force of the United States Army, under operational control of JSOC. The unit's missions primarily involve counterterrorism ...
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. [1] [2] It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state ( Ondo) from South West geopolitical zone and two states ( Abia and Imo) from ...
A delta one product is a derivative with a linear, symmetric payoff profile. That is, a derivative that is not an option or a product with embedded options. Examples of delta one products are Exchange-traded funds, equity swaps, custom baskets, linear certificates, futures, forwards, exchange-traded notes, trackers, and Forward rate agreements .
Lava delta. Lava deltas, similar to river deltas, form wherever sufficient sub-aerial flows of lava enter standing bodies of water. The lava cools and breaks up as it encounters the water, with the resulting fragments filling in the adjacent seabed topography such that the flow can move further offshore sub-aerially.
In quantum mechanics the delta potential is a potential well mathematically described by the Dirac delta function - a generalized function. Qualitatively, it corresponds to a potential which is zero everywhere, except at a single point, where it takes an infinite value. This can be used to simulate situations where a particle is free to move in two regions of space with a barrier between the ...
Delta method. In statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian .
