Adrian Walker (computer scientist). Adrian David Walker is a US Computer Scientist, born in London, England.

Education
Adrian Walker attended Dartington Hall School, an experimental boarding school in England where attendance at classes was optional.  He obtained a bachelor's degree in electrical engineering at Sheffield University (where he also chaired the Arts Society and edited a poetry magazine), and a master's degree in systems engineering
from the University of Surrey. He next obtained a PhD in computer science
from the State University of New York.

Career
He was assistant professor at Rutgers university in New Jersey, then Member of Technical Staff at Bell Labs. He moved to the IBM Almaden Research Center in California as a Research Staff Member then to the IBM Thomas J. Watson Research Center in Yorktown NY as manager of Principles and Applications of Logic Programming.
After 17 years at IBM, he formed his own company, where he works on Internet Business Logic, a system for social knowledge acquisition and use in executable English.

Selected work:  Walker's early work
established a novel correspondence between stable patterns in formalised biological systems and the well known Chomsky hierarchy of languages—regular, context free, and context sensitive. He continued in grammar-based research
by showing how Bayes' theorem can be used to fit a stochastic regular grammar to a collection of data, a result that can be used to inductively infer hidden Markov models. Walker next showed
that, under certain practically useful assumptions, it is possible to compute the semantics of sets of syllogism-like rules in open vocabulary, largely open syntax English, in such a way as to answer English questions put to databases. This relaxes an onerous assumption made in many computational natural language understanding systems—namely, that the vocabulary must be narrowly restricted to obtain a useful level of understanding.
A logical theory of knowledge developed in

is applied in a system on the Web (reference 7, below) that combines three kinds of semantics – (a) data, as in SQL or Resource Description Framework, (b) inference, and (c) English, to answer questions over networked databases, and to explain the results in hypertexted English. The subject knowledge needed to do this (e.g. knowledge about the oil industry, or about energy independence, etc.) can be captured in social network style, by typing executable English into browsers. This contrasts with other social media, such as Twitter and Facebook, in which knowledge written in English is readable, but cannot be executed as a computer program.

Kissinger-Crookes Flying Saucer. The Kissinger-Crookes Flying Saucer is a high-wing homebuilt glider based on the Amcraft Products model aircraft.

Design and development
The Flying Saucer is the first in a series of aircraft designs from Curtiss Kissinger, and LeRoy Crookes capable of carrying a pilot. It received a Patent No. 2,864,567.

The prototype was built using EMT electrical conduit. The wings use pine wood spars, and 1/8 inch plywood covering. The wing chord varies from center to tip to form a circular shape. The wings fold in segments for road travel.

Operational history
The flying saucer was towed aloft on flight tests with a Nash Rambler. The prototype suffered structural damage on the first flight tests.

William McWhirter. William McWhirter (c. 1851–1933) was a Scottish electrical engineer, grandfather of Norris McWhirter, who invented the combined voltmeter and ammeter, from which such (analogue) subsequent meters were developed.

Early life
He was born in Ayr. He went to school at Ayr Academy.

Career
He was apprenticed to his uncle who was a baker. He joined the telegraphic department of the Glasgow and South Western Railway, becoming a divisional inspector.

In 1882 he worked for Messrs Norman & Sons, setting up the first electrical lighting at Glasgow Central station. There were no power stations in Glasgow at the time, and under the arches of the railway viaduct on Argyle Street, a makeshift generator was built from a Robey boiler and engine, with dynamos with copper wire brushes. A nearby shop was also lit with electricity, by an arc lamp, and this new contraption drew large crowds.

In 1884 he formed McWhirter & Co, which opened a works in Govan. This site made big improvements to the efficiency and commutation of the dynamo. In 1897 he formed William McWhirter and Sons Ltd. He went to India in 1899 to improve the country's railway signalling.

Inventions
In 1883 he patented a combined voltmeter and ammeter, a prototype multimeter. It was later manufactured by the General Electric Company.

Institutions
In 1880 he joined the Institution of Electrical Engineers (now the Institution of Engineering and Technology). He was one of the founders of the Scottish Electrical Contractors' Association (now known as SELECT).

Research
In research he cooperated with Prof Silvanus P. Thompson, Prof William Edward Ayrton, Prof John Perry, Prof Andrew Jamieson, and the American Frank J. Sprague. He also worked with Hugo Hirst, 1st Baron Hirst.

Personal life
He married Marian, from Ayr.

One of his sons would be William Allan McWhirter, born in 1889, who became the editor of the Sunday Pictorial (later to become the Sunday Mirror), and managing director from 1944-50 of Associated Newspapers. His grandsons were Norris McWhirter CBE and Ross McWhirter.

Test point. A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals. Test points have three primary uses:

 During development they are used to analyze hardware behavior. This allows characterization of circuit boards (e.g. power consumption, bus bandwidth), validation of the design and evaluation of component selection. For hardware with software components, test points are used to monitor bus signal, provide engineering interfaces and to force behaviors. Not all development test points are incorporated in production devices.
 During manufacturing they are used to verify that a newly assembled device is working correctly. Any equipment that fails this testing is either discarded or sent to a rework station to attempt to repair the manufacturing defects.
 After sale of the device to a customer, test points may be used at a later time to repair the device if it malfunctions, or if the device needs to be re-calibrated after having components replaced.

Test points can be labeled and may include pins for attachment of alligator clips or may have complete connectors for test clips.

Modern miniature surface-mount electronics often simply have a row of unlabeled, tinned solder pads. The device is placed into a test fixture that holds the device securely, and a special surface-contact connector plate is pressed down onto the solder pads to connect them all as a group.

EJOT. EJOT is a medium-sized group of companies with markets including the construction, automotive and consumer electronics industries. The group headquarters are in Bad Berleburg in the Siegen-Wittgenstein region in Germany.

History 

The origin of EJOT is the former Adolf Böhl GmbH & Co. KG, a manufacturer of screws and nails founded in 1922 in Bad Berleburg - Berghausen.

In 1960, after the death of the founder, his nephew Hans W. Kocherscheidt inherited the company. In 1965 he bought the screw producing company Eberhard Jaeger in Bad Laasphe and merged the two companies under the name EJOT.

In 1971 an Engineered Plastic Components production was added to the production in Bad Berleburg. In 1993 EJOT acquired the former Volkseigener Betrieb, Schraubenwerk Tambach GmbH in Tambach-Dietharz, Thuringia. With time, expansion, acquisitions and diversification developed the former screws company into the present business group with approx. 2200 employees. About 1500 employees are working in Germany, further 700 employees belong to foreign offices and connected companies in Europe, Russia, United Arab Emirates, China, Mexico and the United States.

In Mexico, the company produces cold-formed fasteners for various customers in the automotive industry, the electronics industry, household appliances and construction. EJOTATF Fasteners de México is a joint venture between two companies in the industry:

EJOT GmbH & Co. KG, Germany 
ATF Inc., Lincolnwood IL, USA

The plant at the Parque Industrial Millennium in San Luis Potosí augments the San Luis Potosí Assembly, a General Motors assembly plant, among other customers.

Advanced Comprehensive Operating System. Advanced Comprehensive Operating System (ACOS) is a family of mainframe computer operating systems developed by NEC for the Japanese market. It consists of three systems, based on the General Comprehensive Operating System family developed by General Electric, Honeywell, and Bull. Two of these systems, ACOS-2 (based on GCOS 4) and ACOS-4 (based on GCOS 7) are still sold, although only ACOS-4 is under active development. ACOS-6 (based on GCOS 8) is an obsolete high-end mainframe platform, which ceased active development in the early 2000s.

The first two models in NEC's SX series of supercomputers, the SX-1 and the SX-2 (released in 1985), ran an operating system derived from ACOS-4, which was variously called either SX-OS or SXCP (SX System Control Program). However, subsequent SX supercomputers, starting with the SX-3 (released in 1990), instead ran a derivative of Unix.

In late September 2012, NEC announced a return from IA-64 to the previous NOAH line of proprietary mainframe processors for ACOS-4, now produced in a quad-core variant on 40 nm, called NOAH-6.
ACOS-2 runs on Intel Xeon servers.

In June 2022, i-PX AKATSUKI server equipped with NEC's original processor (NOAH-7) was released.

AVIEN. AVIEN is nominally an acronym for Anti-Virus Information Exchange Network, although that expansion is rarely used.

History 
The group arose out of discussions following a presentation by Robert S. Vibert at a Virus Bulletin Conference in 2000 when antivirus specialists from companies including Nortel, Boeing and Prudential decided to implement a forum where they could freely share information concerning AV companies, products, and upcoming malware, including an email-based Early Warning System.

Initially, members of AVIEN were individuals responsible for the security of organizations with a minimum of 1,500 PCs in their care, and excluded antivirus vendors but in 2002 a companion organization AVIEWS (Anti-Virus Information and Early Warning System) was formed which included all members of AVIEN but also encouraged the participation of security vendors and other interested parties. 

In 2007, Syngress published the AVIEN Malware Defense Guide for the Enterprise with contributions by members of AVIEN and AVIEWS.  

The two organizations merged in 2008 under the leadership of Andrew Lee (CEO) and David Harley (COO). In 2011, following his taking up the role of CEO at ESET, Lee announced that he was leaving the running of AVIEN to David Harley, signing himself "(former) AVIEN CEO".

By 2012 the organization had declined to a low-traffic mailing list, a rarely updated web site, and occasional additions to the blog, including resource pages on security topics such as tech support scams and ransomware. Since David Harley's near-complete withdrawal from the security industry in 2019 little has been heard from the AVIEN community, or is expected to be heard.

Dale Weejet 800. The Dale Weejet 800, or Weejet VT-1 was an early light jet intended for high-speed personal transport or primary military training.

Design and development
Harold Dale, an engineer at North American Aviation who had designed several homebuilt aircraft, teamed up with Edward Gagnier, a former North American engineer, to develop the Weejet. The name was registered in February 1952 and the prototype was built in 2 1/2 years.

The Weejet was a two-seat side-by-side, mid-winged all-aluminum, retractable tricycle gear aircraft with a V-tail arrangement. The aircraft was powered by a 920lb thrust Continental-Turbomeca Marbore II J-69-T-15 engine. Air was fed to the engine through two triangular inlets mounted on the inboard wing roots. Fuel was carried in the leading edge of the wings, and tip tanks. The aircraft had oxygen tanks and was pressurized to 3 psi differential pressure. The seats were designed to accommodate parachutes. The rudder pedals were adjustable for different pilot heights.

Operational history
The first test flight was conducted by Harold Dale on 30 March 1956. The aircraft completed several spin tests, but during one test the canopy opened and the aircraft went into an inverted spin. The pilot bailed out safely and the prototype crashed after performing an unmanned inverted loop. It was later found that the trim tab was set to full nose-down attitude during the test. A scheduled demonstration of the aircraft for the U.S. Navy was canceled. No other Weejets were produced.

GER Class N31. The GER Class N31 was a class of eighty-two 0-6-0 steam locomotives designed by James Holden for the Great Eastern Railway. Eighteen passed to the London and North Eastern Railway (LNER) at the 1923 grouping and received the LNER classification J14.

History
These goods locomotives had  cylinders,  driving wheels, and a  boiler. Eighty-one were built at Stratford Works between 1893 and 1898.

Table of orders and numbers

Class 127
In addition, when the Class 127 locomotive was rebuilt from compound to simple in 1895, it was then included into Class N31.

Performance
They were not particularly successful locomotives. Although nicknamed Swifts, they were sluggish locomotives, due to the placement of the valve chests underneath the cylinders.

Withdrawals
Withdrawals started in 1908, and by the end of 1922, only eighteen were left in service. The LNER allocated numbers 7000 higher than the locomotives' GER numbers, but withdrawals continued, and by 1925 the class was extinct.

Steinruck SCS-1. The Steinruck SCS-1 is an American high-wing, single-seat, V-tailed glider that was designed by A.C. Cordas and constructed by Wade Steinruck.

Design and development
Steinruck worked on the SCS-1 for many years in his spare time at his home in Spring Valley, California, completing the aircraft in 1959.

The SCS-1 is built predominantly from aluminium. It features a V-tail and a three-piece wing with a NACA 33012 airfoil. The spoilers are located in a hatch that is behind the canopy.

Operational history
The SCS-1 has been flown on several recreational  out and return and triangle flights.

In June 2011 the aircraft was still registered with the Federal Aviation Administration to Steinruck, 52 years after its completion.

Flake salt. Flake salt refers to a category of salt characterized by their dry, plate-like ("lamellose") crystals. Their structure is a result of differing growth rates between the faces and edges of the crystal, an effect that can be achieved in various ways. Flake salt may occur naturally but can also be produced by a variety of methods, including boiling brine over metal salt pans or evaporating it in greenhouse solar evaporators. The technologies used as well as atmospheric conditions can yield varying crystal structures. Flake salts can form as irregular shavings, pyramidal shapes, boxes, or potato chip-like laminated crystals. These salts tend to have lower trace mineral content than other salts, giving them a stronger salty taste. Most form as thin, flattened out crystals with a large surface area and low mass that give them a crunchy texture and relatively fast dissolution rate. Because of the salts' delicate structures, selmeliers tend to use them as finishing salts.
