Toda Of Navarre
Toda Aznárez (Basque: ''Tota Aznar''; d. 15 October 958), known as Toda of Pamplona, was queen of Pamplona by her marriage to Sancho I. She ruled the kingdom as regent during the minority of her son García Sánchez I from 931. She was herself descended from the previous royal dynasty, Aritza. Family Toda was the daughter of Aznar Sánchez, lord of Larraun, paternal grandson of King García Íñiguez of Pamplona, while her mother Onneca Fortúnez was a daughter of King Fortún Garcés. Thus, Toda was a descendant of the Aritza dynasty of Navarrese monarchs. Toda was an aunt or cousin of Caliph Abd-al-Rahman III. Toda was married to King Sancho I of Pamplona, with whom she had the following children: * Urraca, queen of León from 931 until 951 as the wife of Ramiro II * Oneca, queen of León from 926 until 931 as the wife of Alfonso IV * Sancha, countess of Castile as the wife of Fernán González * Velasquita, married first to Count Munio Vélaz of Álava, then to Galin ...

Toda People
Toda people are a Dravidian ethnic group who live in the Indian states of Tamil Nadu. Before the 18th century and British colonisation, the Toda coexisted locally with other ethnic communities, including the Kota, Badaga and Kurumba, in a loose caste-like society, in which the Toda were the top ranking. During the 20th century, the Toda population has hovered in the range 700 to 900. Although an insignificant fraction of the large population of India, since the early 19th century the Toda have attracted "a most disproportionate amount of attention because of their ethnological aberrancy" and "their unlikeness to their neighbours in appearance, manners, and customs". The study of their culture by anthropologists and linguists proved significant in developing the fields of social anthropology and ethnomusicology. The Toda traditionally live in settlements called ', consisting of three to seven small thatched houses, constructed in the shape of half-barrels and located across ...

Toda Language
Toda is a Dravidian language noted for its many fricatives and trills. It is spoken by the Toda people, a population of about one thousand who live in the Nilgiri Hills of southern India. The Toda language originated from Toda-Kota subgroup of South Dravidian. Phonemic inventory Vowels For a Dravidian language, Toda's sixteen vowels is an unusually large number. There are eight vowel qualities, each of which may occur long or short. There is little difference in quality between the long and short vowels, except for , which occurs as when short and as when long. Consonants Toda has an unusually large number of fricatives and trills. Its seven places of articulation are the most for any Dravidian language. The voiceless laterals are true fricatives, not voiceless approximants; the retroflex lateral is highly unusual among the world's languages.Spajić et al. (1994) Voiceless fricatives are allophonically voiced intervocalically in Toda. There are also the invariably vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toda Embroidery
The Toda Embroidery, also locally known as "pukhoor", is an art work among the Toda pastoral people of Nilgiris, in Tamil Nadu, made exclusively by their women. The embroidery, which has a fine finish, appears like a woven cloth but is made with use of red and black threads with a white cotton cloth background. Both sides of the embroidered fabric are usable and the Toda people are proud of this heritage. Both men and women adorn themselves with the embroidered cloaks and shawls. This handicraft product is listed as a geographically tagged product and is protected under the Geographical Indications of Goods (Registration & Protection) Act (GI Act) 1999 of the Government of India. It was registered by the Controller General of Patents Designs and Trademarks under the title "Toda Embroidery" and recorded at GI Application number 135 under Class 24, Class 25, and Class 26 as Textiles and Textile Goods, clothing, and Embroidery, respectively, in March 2013.

Toda Lattice
The Toda lattice, introduced by , is a simple model for a one-dimensional crystal in solid state physics. It is famous because it is one of the earliest examples of a non-linear completely integrable system. It is given by a chain of particles with nearest neighbor interaction, described by the Hamiltonian :\begin H(p,q) &= \sum_ \left(\frac +V(q(n+1,t)-q(n,t))\right) \end and the equations of motion :\begin \frac p(n,t) &= -\frac = e^ - e^, \\ \frac q(n,t) &= \frac = p(n,t), \end where q(n,t) is the displacement of the n-th particle from its equilibrium position, and p(n,t) is its momentum (mass m=1), and the Toda potential V(r)=e^+r-1. Soliton solutions Soliton solutions are solitary waves spreading in time with no change to their shape and size and interacting with each other in a particle-like way. The general N-soliton solution of the equation is : \begin q_N(n,t)=q_+ + \log \frac , \end where :C_N(n,t)=\Bigg(\frac\Bigg)_, with :\gamma_j(n,t)=\gamma_j\,e^ where \kappa ...

Toda Field Theory
In mathematics and physics, specifically the study of field theory and partial differential equations, a Toda field theory, named after Morikazu Toda, is specified by a choice of Kac–Moody algebra and a specific Lagrangian. Fixing the Kac–Moody algebra to have rank r, that is, the Cartan subalgebra of the algebra has dimension r, the Lagrangian can be written \mathcal=\frac\left\langle \partial_\mu \phi, \partial^\mu \phi \right\rangle -\frac\sum_^r n_i \exp(\beta \langle\alpha_i, \phi\rangle). The background spacetime is 2-dimensional Minkowski space, with space-like coordinate x and timelike coordinate t. Greek indices indicate spacetime coordinates. For some choice of root basis, \alpha_i is the ith simple root. This provides a basis for the Cartan subalgebra, allowing it to be identified with \mathbb^r. Then the field content is a collection of r scalar fields \phi_i, which are scalar in the sense that they transform trivially under Lorentz transformations of the under ...

Oscillator Toda
In physics, the Toda oscillator is a special kind of nonlinear oscillator. It represents a chain of particles with exponential potential interaction between neighbors. These concepts are named after Morikazu Toda. The Toda oscillator is used as a simple model to understand the phenomenon of self-pulsation, which is a quasi-periodic pulsation of the output intensity of a solid-state laser in the transient regime. Definition The Toda oscillator is a dynamical system of any origin, which can be described with dependent coordinate ~x~ and independent coordinate ~z~, characterized in that the evolution along independent coordinate ~z~ can be approximated with equation : \frac+ D(x)\frac+ \Phi'(x) =0, where ~D(x)=u e^+v~, ~\Phi(x)=e^x-x-1~ and prime denotes the derivative. Physical meaning The independent coordinate ~z~ has sense of time. Indeed, it may be proportional to time ~t~ with some relation like ~z=t/t_0~, where ~t_0~ is constant. The derivative ~\dot x=\frac may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toda Bracket
In mathematics, the Toda bracket is an operation on homotopy classes of maps, in particular on homotopy groups of spheres, named after Hiroshi Toda, who defined them and used them to compute homotopy groups of spheres in . Definition See or for more information. Suppose that :W\stackrel X\stackrel Y\stackrel Z is a sequence of maps between spaces, such that the compositions g\circ f and h\circ g are both nullhomotopic. Given a space A, let CA denote the cone of A. Then we get a (non-unique) map : F\colon CW\to Y induced by a homotopy from g\circ f to a trivial map, which when post-composed with h gives a map :h\circ F\colon CW\to Z. Similarly we get a non-unique map G\colon CX\to Z induced by a homotopy from h\circ g to a trivial map, which when composed with C_f\colon CW\to CX, the cone of the map f, gives another map, : G\circ C_f\colon CW\to Z. By joining together these two cones on W and the maps from them to Z, we get a map : \langle f, g, h\rangle\colon SW\to Z repr ...

Toda Fibration
In mathematics, the EHP spectral sequence is a spectral sequence used for inductively calculating the homotopy groups of spheres localized at some prime ''p''. It is described in more detail in and . It is related to the EHP long exact sequence of ; the name "EHP" comes from the fact that George W. Whitehead named 3 of the maps of his sequence "E" (the first letter of the German word "Einhängung" meaning "suspension"), "H" (for Heinz Hopf, as this map is the second Hopf–James invariant), and "P" (related to Whitehead products). For p = 2 the spectral sequence uses some exact sequences associated to the fibration :S^n(2)\rightarrow \Omega S^(2)\rightarrow \Omega S^(2), where \Omega stands for a loop space and the (2) is localization of a topological space In mathematics, well-behaved topological spaces can be localized at primes, in a similar way to the localization of a ring at a prime. This construction was described by Dennis Sullivan in 1970 lecture notes that were finally p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
