A copper wiring device made up of roughly 60 intertwined individual copper wirings, wrapped in thick yellow rubber that had a serial number on it.

Conceivably, slices of these preserved brains could be digitized and reconfigured in a computer to reconstruct a person's connectome—the totality of a brain's specific internal wirings.

Science is revealing the ways that the physiology of our psychology can be found across species: the common neuronal structures and attendant nerve wirings that we share in varying measures with a startling array of both vertebrates and invertebrates, including fellow primates, elephants, whales, parrots, bees and fruit flies.

Nor were the British cryptologists whom Bertrand contacted able to make any headway. In December 1932, Bertrand shared intelligence obtained from Asché with the Polish General Staff's Cipher Bureau (Biuro Szyfrów). Mathematician-cryptologist Marian Rejewski had already set up a system of equations describing the operation of the then new German Army Enigma rotor-wirings. The key-settings lists provided by Schmidt helped fill in enough of the unknowns in Rejewski's formulae, allowing him to speedily solve the equations and recover the wirings.

During the incumbency, two fabricated school building was added, the Vocational and the Annex buildings. The school population increased every year. The number of classrooms became inadequate when the building fronting Manlunas St. was burned on February 26, 1978 due to faulty electrical wirings. It was replaced to Bagong Lipunan Building constructed by DPWH in 1978.

Mohan and Chopra. Eagles Over Bangladesh. p. 391 The airplanes had been scuttled by cutting their wirings and small arms fire before the surrender by Pakistani forces. The Hiller was taken over by Bangladesh Army, while Bengali airmen set to work on fixing the aircraft. By March 1972, 8 Sabers, one T-33 and the Alouette were airworthy.

About 9 or 10 December 1932, the documents were given to Rejewski. They enabled him to reduce the number of unknowns and solve the wirings of the rotors and reflector. There was another obstacle to overcome, however. The military Enigma had been modified from the commercial Enigma, of which Rejewski had had an actual example to study.

Gleaner was completed by William Gray & Company, Hartlepool, as a survey vessel, but she was converted into a minesweeper when the war began. On 12 February 1940, Gleaner sank German U-boat U-33 () using depth charges and deck gun. The captain was Lt.Cdr. H. P. Price, RN. The British seized some materials from the U-boat, including Enigma machine rotors VI and VII, whose wirings were unknown at the time.

In this case the plugboard acted as a "fourth rotor" in the rotor machine's workings. Plugboard wirings were part of the "day settings" that specified which rotors to insert into which slot, and which plugboard connections to make. In practice the plugboard did improve the security of the cypher being generated, but as it did not change with every keypress, unlike the rotors, its impact was limited. See Cryptanalysis of the Enigma.

The first bombe, code-named Victory, was installed in March 1940 while the second version, Agnus Dei or Agnes, incorporating Welchman's new design, was working by August 1940. The bombe was designed to discover some of the daily settings of the Enigma machines on the various German military networks: specifically, the set of rotors in use and their positions in the machine; the rotor core start positions for the message—the message key—and one of the wirings of the plugboard.

In April 1937Hodges (1983) p. 176 Knox made his first decryption of an Enigma encryption using a technique that he called buttoning up to discover the rotor wirings and another that he called rodding to solve messages. This relied heavily on cribs and on a crossword- solver's expertise in Italian, as it yielded a limited number of spaced-out letters at a time. Britain had no ability to read the messages broadcast by Germany, which used the military Enigma machine.

In the case of the reflectors, in this example Wide is taken (Reflector B in the table below) where an is returned as a and the is returned as an . Notice that the wirings are connected as a loop between two letters. When a rotor has stepped, the offset must be taken into account to know what the output is, and where it enters the next rotor. If for example rotor I is in the -position, an enters at the letter which is wired to the .

The current entry wheel (Eintrittswalze in German), or entry stator, connects the plugboard to the rotor assembly. If the plugboard is not present, the entry wheel instead connects the keyboard and lampboard to the rotor assembly. While the exact wiring used is of comparatively little importance to security, it proved an obstacle to Rejewski's progress during his study of the rotor wirings. The commercial Enigma connects the keys in the order of their sequence on a QWERTZ keyboard: Q->A, W->B, E->C and so on.

These mathematical techniques, combined with material supplied by Gustave Bertrand, chief of French radio intelligence, enabled him to reconstruct the internal wirings of the machine's rotors and nonrotating reflector. "The solution", writes Kahn, "was Rejewski's own stunning achievement, one that elevates him to the pantheon of the greatest cryptanalysts of all time." Rejewski used a mathematical theorem—that two permutations are conjugate if and only if they have the same cycle structure—that mathematics professor and Cryptologia co- editor Cipher A. Deavours describes as "the theorem that won World War II".Cipher A. Deavours, in an afterword to .

" The settings provided by French Intelligence covered two months that straddled a changeover period for the rotor ordering. A different rotor happened to be in the right-hand position for the second month, and so the wirings of two rotors could be recovered by the same method. Rejewski later recalled: "Finding the [wiring] in the third [rotor], and especially... in the [reflector], now presented no great difficulties. Likewise there were no difficulties with determining the correct torsion of the [rotors'] side walls with respect to each other, or the moments when the left and middle drums turned.

Brownhills was also formerly home to the wirings manufacturer Electrium's last UK-based factory, but this has closed, with manufacturing shifted overseas and commercial staff moved to a new site in Cannock. In 2006, the site was converted into a mixed-use facility dubbed Toll Point, with Walsall Council among those moving to the site. Many people are also employed at the town's large branch of Tesco which is open 24 hours a day on weekdays and is large enough to have its own petrol station. Before being taken over by Tesco, the store was a branch of Hillards, and an earlier Tesco store in the town had been forced to close as it could not compete with Hillards.

Zarih over the qabr (grave) of one of the Kazimayn Repairs to the crumbling structure of the main courtyard of the mosque and its surrounding rooms were carried out in three phases, spanning a period of four months, before the end of 2007. The project entailed the stripping off of the old crumbling walls throughout the courtyard, the addition of various reinforcements to the walls and ceilings, as well as maintenance on the electrical wirings throughout the mosque. Once the inner structure was completed, the floors and walls were then plated in various kinds of marble. Updates to the cooling units of the mosque began in late 2008, and new water filtration units were installed on November 28, 2008.

Alberto Nero, resumed the major repairs and repainting of Our Lady's Basilica. The first move was to treat the whole church and complex with anti-termite chemicals to control and exterminate those destructive pests which have already attacked and damaged considerably both structures. By September 1994, the leaking roofs of the Basilica have been fully repaired and repainted, the damaged ceilings rehabilitated and repainted together with the interior walls of the Basilica, the electrical wirings and installations renovated, the gigantic and ugly chandeliers were replaced with the more luminous and more economical Highbay luminaire lamps, the Cross at the Basilica dome provided with a neon light tubes which distinguishes the Basilica at night even from afar and finally a 20 KVA standby power generator had been purchased and installed to provide emergency lights during brown-outs. On November 3, 1994, the repair works and repainting of the Basilica Minore's exterior walls were resumed.
