Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [1] [2] Atmospheric effects in optical remote sensing are significant and complex, dramatically altering the spectral nature of the radiation reaching the remote ...
Tool use by sea otters. A sea otter using a rock to break open a shell. The sea otter, Enhydra lutris, is a member of the Mustelidae that is fully aquatic. Sea otters are the smallest of the marine mammals, but they are also the most dexterous. Sea otters are known for their ability to use stones as anvils or hammers to facilitate access to ...
K correction. K correction converts measurements of astronomical objects into their respective rest frames. The correction acts on that object's observed magnitude (or equivalently, its flux ). Because astronomical observations often measure through a single filter or bandpass, observers only measure a fraction of the total spectrum, redshifted ...
SeaTools is a computer hard disk analysis software developed and released by Seagate Technology. It exists as a version for DOS (bundled in a bootable medium with FreeDOS) and Microsoft Windows. It can perform short and long drive self-tests and read/write tests, extract S.M.A.R.T. indicators and drive information, and perform advanced tests.
RIAA equalization is a form of pre-emphasis on recording and de-emphasis on playback. A recording is made with the low frequencies reduced and the high frequencies boosted, and on playback, the opposite occurs. The net result is a flat frequency response, but with attenuation of high-frequency noise such as hiss and clicks that arise from the ...
qudit ( d -dimensional) v. t. e. The general definition of a qubit as the quantum state of a two- level quantum system. In quantum computing, a qubit ( / ˈkjuːbɪt /) or quantum bit is a basic unit of quantum information —the quantum version of the classic binary bit physically realized with a two-state device.

(ODFL) is an American regional, inter-regional and national less than truckload shipping (LTL) company. In addition to its core LTL services, the company offers expedited, logistics and household ...
The simple Bonferroni correction rejects only null hypotheses with p-value less than or equal to , in order to ensure that the FWER, i.e., the risk of rejecting one or more true null hypotheses (i.e., of committing one or more type I errors) is at most . The cost of this protection against type I errors is an increased risk of failing to reject ...
