unusual facts about lattice



Adelsheim

Transmission tower at 49° 24' 38" N, 9° 23' 29" E (freestanding steel lattice construction, bearing until 1993 an SWR MW transmission antenna in the form of a long-wire antenna)

Alacránite

Further studies of a single crystal of alacranite with dimensions (30 × 60 × 120 mm was examined using direct methods, Fourier syntheses and structure refinement resulting in intensities violating the C lattice type and symmetries like h0l reflections with l = 2n + 1 were absent.

Albatros C.II

The unusual tail structure used an open frame structure with a conventional fin and rudder and gave rise to the nickname Gitterschwanz (en: lattice tail).

Alexander Kuzemsky

Applications to the lattice fermion models such as Hubbard/Anderson models and to the Heisenberg model of ferro- and antiferromagnet, which manifest the operational ability of the method were given.

Baba Mountain, Macedonia

On Pelister mountain, there is a TV transmitter using an additionally guyed lattice steel mast as antenna tower.

BCS theory

:* Isotope effect on the critical temperature, suggesting lattice interactions.

Brillouin

Brillouin zone, a primitive cell of the reciprocal lattice of a crystal

Chancel

The word "chancel" derives from the French usage of chancel from the Late Latin word cancellus meaning "lattice".

Circle packing

Axel Thue provided the first proof that this was optimal in 1890, showing that the hexagonal lattice is the densest of all possible circle packings, both regular and irregular.

COSMOSPACE

While UNIQUAC is a first order approximation, COSMOSPACE gives the exact solution of a lattice model in which pairwise molecule surfaces interact.

Extended Affix Grammar

The remedy proposed was to switch to the much simpler Affix Grammar over a Finite Lattice (AGFL) instead, in which metagrammars can only produce simple finite languages.

Guitar bracing

The Australian guitarmaker Greg Smallman introduced guitars with an extremely thin soundboard, which is supported by bracing in the shape of a lattice.

Hawa Mahal

Besides this, the lattice also provides cool air caused by the Venturi effect (doctor breeze) through the intricate pattern and thereby air conditioning the whole area during the high temperatures in summers.

Holger Bech Nielsen

Several physics concepts are named after him, e.g. Nielsen-Olesen Vortex and the Nielsen-Ninomiya no-go theorem for representing chiral fermions on the lattice.

Jali

A jali or jaali, (Gujarati: જાળી) is the term for a perforated stone or latticed screen, usually with an ornamental pattern constructed through the use of calligraphy and geometry.

Kane quantum computer

Often thought of as a hybrid between quantum dot and NMR quantum computers, the Kane computer is based on an array of individual phosphorus donor atoms embedded in a pure silicon lattice.

Lattice Boltzmann methods

LGA suffer from several innate defects for use in hydrodynamic simulations: lack of Galilean invariance for fast flows, statistical noise and poor Reynolds number scaling with lattice size.

It is therefore common to raise the lattice Mach number to something much larger than the real Mach number, and compensating for this by raising the viscosity as well in order to preserve the Reynolds number.

Lattice graph

The rook's graph (the graph that represents all legal moves of the rook chess piece on a chessboard) is also sometimes called the lattice graph.

LatticeMico32

It is possible to embed a LatticeMico32 core into Xilinx and Altera FPGAs, in addition to the Lattice parts the LatticeMico32 was developed for.

Lead–acid battery

In 1881, Camille Alphonse Faure invented an improved version that consisted of a lead grid lattice, into which a lead oxide paste was pressed, forming a plate.

Link-Belt Construction Equipment

The Link-Belt Construction Equipment Company is a wholly owned subsidiary of Sumitomo Heavy Industries based in Lexington, Kentucky, which manufactures telescopic and lattice boom cranes.

M-group

Iwasawa group or modular group, in the study of subgroup lattices, a group whose subgroup lattice is modular

Maestro guitars

Maestro’s classical guitars are made in the original Spanish way, with either a traditional fan-bracing or Greg Smallman’s lattice-bracing.

Oxygen-free

Oxygen-free copper, pure copper without oxygen in its crystal lattice;

Puente de las Calabazas

Puente de las Calabazas is a lattice girder bridge near Coamo, Puerto Rico that dates from 1882.

Roker Park

In 1929 the old wooden grandstand was demolished and replaced by a new Main Stand, which was designed by Archibald Leitch, whose influence, the criss-cross lattice work, can still be seen at Ibrox (Rangers), Home Park (Plymouth Argyle) and Goodison Park (Everton).

Rudolf Wille

His most celebrated work is the invention of Formal concept analysis, a supervised machine learning technique that applies mathematical lattice theory to organize data based on objects and their shared attributes.

Sidi Saiyyed Mosque

This intricately carved lattice stone window is the Sidi Saiyyed Jali, the unofficial symbol of city of Ahmedabad and the inspiration for the design of the logo of the Indian Institute of Management Ahmedabad.

Surface properties of transition metal oxides

The structure of binary oxides can be predicted on the basis of the relative sizes of the metal and oxide ions and the filling of holes in a close packed oxide lattice.

The 85 Ways to Tie a Tie

In their papers (which are technical) and book (which is for a lay audience, apart from an appendix), the authors show that necktie knots are equivalent to persistent random walks on a triangular lattice, with some constraints on how the walks begin and end.

Transmission tower

Lattice steel towers are generally made of angle-profiled steel beams (L- or T-beams).

Veech surface

In mathematics, a Veech surface is a translation surface (X,ω) (a Riemann surface X with a holomorphic 1-form ω) whose group SL(X,ω) of affine diffeomorphisms is a lattice in SL2(R) (a discrete subgroup of cofinite volume).

Vertex operator algebra

Important examples of vertex operator algebras include lattice VOAs (modeling lattice conformal field theories), VOAs given by representations of affine Kac-Moody algebras (from the WZW model), the Virasoro VOAs (i.e., VOAs corresponding to representations of the Virasoro algebra) and the moonshine module V, constructed by Frenkel, Lepowsky and Meurman in 1988.

William Milnor Roberts

He was in charge of construction of a two-level lattice-truss bridge across the Susquehanna River at Harrisburg, Pennsylvania.
