'Pataphysics or pataphysics is a difficult-to-define literary trope invented by French writer Alfred Jarry. One definition is that "pataphysics is a branch of philosophy or science that examines imaginary phenomena that exist in a world beyond metaphysics. Another attempt at a definition interprets'pataphysics as an idea that "the virtual or imaginary nature of things as glimpsed by the heightened vision of poetry or science or love can be seized and lived as real". Jarry defines'pataphysics in a number of statements and examples, including that it is "the science of imaginary solutions, which symbolically attributes the properties of objects, described by their virtuality, to their lineaments". A practitioner of ` pataphysics is a pataphysicist. There are over one hundred definitions of'pataphysics; some examples are shown below. Pataphysics is the science of that, superinduced upon metaphysics, whether within or beyond the latter's limitations, extending as far beyond metaphysics as the latter extends beyond physics....'Pataphysics will be, above all, the science of the particular, despite the common opinion that the only science is that of the general.'Pataphysics will examine the laws governing exceptions, will explain the universe supplementary to this one.'Pataphysics is patient.

As cited in Pataphysics passes from one state of apparent definition to another. Thus it can present itself under the aspect of a liquid or a solid; as cited in Pataphysics "the science of the particular" does not, study the rules governing the general recurrence of a periodic incident so much as study the games governing the special occurrence of a sporadic accident. Jarry performs humorously on behalf of literature what Nietzsche performs on behalf of philosophy. Both thinkers in effect attempt to dream up a "gay science" whose joie de vivre thrives wherever the tyranny of truth has increased our esteem for the lie and wherever the tyranny of reason has increased our esteem for the mad; the word'pataphysics is a contracted formation, derived from the Greek τὰ ἐπὶ τὰ μεταφυσικά, a phrase or expression meaning "that, above metaphysics", is itself a sly variation on the title of Aristotle's Metaphysics, which in Greek is "τὰ μετὰ τὰ φυσικά". Jarry mandated the inclusion of the apostrophe in the orthography,'pataphysique and'pataphysics, " avoid a simple pun".

The words pataphysician or pataphysicist and the adjective pataphysical should not include the apostrophe. Only when consciously referring to Jarry's science itself should the word'pataphysics carry the apostrophe; the term pataphysics is a paronym of metaphysics. Since the apostrophe in no way affects the meaning or pronunciation of pataphysics, this spelling of the term is a sly notation, to the reader, suggesting a variety of puns that listeners may hear, or be aware of; these puns include patte à physique, as interpreted by Jarry scholars Keith Beaumont and Roger Shattuck, pas ta physique, pâte à physique. The term first appeared in print in the text of Alfred Jarry's play Guignol in the 28 April 1893 issue of L'Écho de Paris littéraire illustré, but it has been suggested that the word has its origins in the same school pranks at the lycée in Rennes that led Jarry to write Ubu Roi. Jarry considered Ibicrates and Sophrotatos the Armenian as the fathers of this "science"; the Collège de'Pataphysique, founded in 1948 in Paris, France, is "a society committed to learned and inutilious research".

The motto of the college is Latin: Eadem mutata resurgo. The permanent head of the college is the Inamovable Curator, Dr. Faustroll, assisted by Bosse-de-Nage: both are fictional; the Vice-Curator is the "most senior living entity" in the college's hierarchy. The current Vice-Curatrice is Tanya Peixoto of the London Institute of'Pataphysics and Bookartbookshop, she was elected in 2014 to succeed Her Magnificence Lutembi – a crocodile who succeeded Opach, The Baron Mollet and Doctor Sandomir. Jean-Christophe Averty was appointed Satrap in 1990. Publications of the college called Latin: Viridis Candela, include the Cahiers and the Subsidia Pataphysica. Notable members have included Noël Arnaud, Jean-Christophe Averty, Luc Étienne, François Le Lionnais, Jean Lescure, Raymond Queneau, Boris Vian, Eugène Ionesco, Jacques Carelman, Joan Miró, Man Ray, Max Ernst, Julien Torma, Roger Shattuck, Groucho and Harpo Marx, Baron Jean Mollet, Philippe de Chérisey, Irénée Louis Sandomir, Marcel Duchamp, Rolando Villazón, Fernando Arrabal and Gavin Bryars.

The Oulipo began as a subcommittee of the college. Although France had been always the centre of the pataphysical globe, there are followers up in different cities around the world. In 1966 Juan Esteban Fass

Multidelay block frequency domain adaptive filter

The Multidelay block frequency domain adaptive filter algorithm is a block-based frequency domain implementation of the Least mean squares filter algorithm. The MDF algorithm is based on the fact that convolutions may be efficiently computed in the frequency domain. However, the algorithm differs from the Fast LMS algorithm in that block size it uses may be smaller than the filter length. If both are equal MDF reduces to the FLMS algorithm; the advantages of MDF over the LMS algorithm are: Lower algorithmic complexity Partial de-correlation of the input Let N be the length of the processing blocks, K be the number of blocks and F denote the 2Nx2N Fourier transform matrix. The variables are defined as: e _ = F T x _ k = d i a g X _ = d _ = F T With normalisation matrices G 1 and G 2: G 1 = F F H G ~ 2 = F F H G 2 = d i a g In practice, when multiplying a column vector x by G 1 {\displa

Mount Harkin

Mount Harkin is a 2,979-metre mountain summit located in the Kootenay River Valley along the eastern border of Kootenay National Park. Park visitors can see the peak from Highway 93 known as the Banff-Windermere Highway, it is part of the Mitchell Range, a sub-range of the Canadian Rockies of British Columbia, Canada. Its nearest higher peak is 14.0 km to the northeast. The mountain was named in 1923 by Morrison P. Bridgland in honor of James Bernard Harkin, Canada's first National Parks commissioner from 1911 until 1936. Harkin established 11 new national parks and has been called the "Father of the National Parks of Canada." The mountain's name was adopted in 1924 by the Geographical Names Board of Canada. Bridgland was a Dominion Land Surveyor. Mount Harkin is composed principally of Ottertail limestone, a sedimentary rock laid down during the Precambrian to Cambrian periods and pushed east and over the top of younger rock during the Laramide orogeny. Based on the Köppen climate classification, Mount Harkin is located in a subarctic climate with cold, snowy winters, mild summers.

Temperatures can drop below −20 °C with wind chill factors below −30 °C. Precipitation runoff from the mountain drains east into tributaries of the Cross River, or directly west to the Kootenay River.
