Southwest Airlines, the pioneering low-cost carrier, is facing a campaign by an activist investor to overhaul a business model it says is outdated, putting pressure on CEO Robert Jordan and ...
The Delta name in 1965 was an upscale trim line of the Dynamic 88, the Dynamic 88 Delta, replacing the previous top-series B-body Olds, the Super 88. Early '65s were referred to as Dynamic 88 Deltas, but within a few weeks after the start of the model year, Olds began marketing the line as a separate series known as the Delta 88.
Delta model (after the Greek letter Delta, standing for transformation and change) is a customer-based approach to strategic management. [1][2][3] Compared to a philosophical focus on the characteristics of a product (product economics), the model is based on consumer economics. The aim is to create a very strong bond between the company and ...
In physics and probability theory, Mean-field theory (MFT) or Self-consistent field theory studies the behavior of high-dimensional random models by studying a simpler model that approximates the original by averaging over degrees of freedom (the number of values in the final calculation of a statistic that are free to vary). Such models ...
In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as sequence of symbols (e.g., A, C, G, and T in the case of DNA or the 20 "standard" proteinogenic amino acids in the case of ...
An example of an erosional avulsion is the 2006 avulsion of the Suncook River in New Hampshire, in which heavy rains caused flow levels to rise. The river level backed up behind an old mill dam, which produced a shallowly-sloping pool that overtopped a sand and gravel quarry, connected with a downstream section of channel, and cut a new shorter ...
The delta function was introduced by physicist Paul Dirac, and has since been applied routinely in physics and engineering to model point masses and instantaneous impulses. It is called the delta function because it is a continuous analogue of the Kronecker delta function, which is usually defined on a discrete domain and takes values 0 and 1.
Delta encoding. Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required (e.g., in revision ...
