Ephraim R. McLean. Ephraim R. McLean (born January 7, 1936) is an American organizational theorist, and Regents' Professor (Emeritus) of Information Systems and holder of the G.E. Smith (GRA) Eminent Scholars' Chair at the J. Mack Robinson College of Business. Known as one of the founders of the MIS discipline in the 1960s, his work with William H. DeLone on the information systems success model is world-renowned.

Life and work
McLean obtained his BS and MS in Mechanical Engineering in 1958 at Cornell University, his MS in Business Administration in 1967 from Massachusetts Institute of Technology, where in 1970 he also obtained his PhD.

After his graduation at Cornell University, McLean served at the U.S. Ordnance Corps, and then joined Procter & Gamble. He moved from manufacturing management into computer systems analysis. In 1965 he joined the MIT Sloan School of Management faculty, where he wrote the MIS field's first books on computer and management. In 1969 he moved to the UCLA Anderson Graduate School of Management, where he founded one of the world's first MIS department.

Eventually in 1987 he moved to the J. Mack Robinson College of Business at the Georgia State University, where he became Professor in information Systems, chairman of the Department of Computer Information Systems, and Director of its Center for Research in Information Systems.

Shaanxi KJ-500. The Shaanxi KJ-500 (Chinese: 空警-500; pinyin: Kōngjǐng Wǔbǎi; literally: "Air Warning 500") is a third-generation airborne early warning and control (AEW&C) aircraft used by the Chinese People's Liberation Army Air Force (PLAAF). It was built by Shaanxi Aircraft Corporation, and is based on the Y-9 airframe.

Development
Since the beginning of the 21st century, the detection range and the accuracy of airborne radars have been increasing, and fighters equipped with various types of air-to-air missiles and low-altitude cruise missiles continue to improve in performance, creating a demand for a more capable AEW&C. To address the above issues, China started the development of the KJ-500, its third AEW&C, in the late 2000s. The KJ-500 was required to have three important features, which are good detection capability, good identification ability, and quick responsiveness. The KJ-500 was also required to be the core force of the information combat system, its equipped technology has four major characteristics, which are networking, multi-functionality, high-integration, and lightweight.

The aircraft carries a fixed dorsal radome containing three AESA radar arrays for 360-degree coverage and is said to be more efficient than the two-planar 'balance beam' array design used on the earlier KJ-200. Production of older AEW&C types reportedly ceased production in 2018 in response to the KJ-500 reaching full operational capability.

Operational history
In March 2022, General Kenneth Wilsbach, commander of U.S. Pacific Air Forces, identified the KJ-500 as enablers for long-range Chinese air-to-air missiles.

Variants
KJ-500 Base variant
KJ-500H Variant for PLA Navy.
KJ-500A Improved variant with an aerial refueling probe. Debut in Zhuhai Airshow 2022.

Operators
 People's Republic of China
 People's Liberation Army Air Force - 20 KJ-500
 People's Liberation Army Naval Air Force - 14+ KJ-500H

Specifications
Limited performance parameters of KJ-500 have been published as follows:
 Max speed (km/h): 550
 Max range (km): 5700
 Max endurance (h): 12
 Max takeoff weight(tons): 77
 Range against fighter sized targets (km): 470

School Safety Preparedness Drill. School Safety Preparedness Drill (SSPD) is an annual earthquake preparedness drill being organised in schools of North and North Eastern states of India commemorating 4 April 1905 Kangra earthquake.

The two non-governmental organisations GeoHazards Society (GHS) and GeoHazards International (GHI) has been working for earthquake safety in South Asia for many years. In the year 2009 both the organisations along with Library of Tibetan Works and Archives together decided to mark the most destructive Kangra earthquake at Dharamshala in India. Considering the vulnerability of the school children in one of the most earthquake prone region of the world a School Safety Preparedness Drill was organised in the Tibetan schools along the Himalayas in India at 11:00 morning. About 7,500 children participated in the first ever such kind of a drill in India on 4 April 2009 in 25 Tibetan schools.

During the SSPD the schools prepare for an earthquake scenario and when the shaking starts the children along with staff perform a Drop Cover Hold on under sturdy tables and desks preparing to save themselves from falling objects. 

In order to prevent complacency among the children if the earthquake was small, the teachers will instead shake the children’s desks to emulate a real earthquake. This has led to some injuries of children.

When the shaking stops everybody evacuates to a pre-designated assembly area followed by a debriefing.  
 
With every passing year the drill started expanding to new areas covering more children both at Tibetan and non-Tibetan schools. In the 5th SSPD in 2013 more than 50,000 children participated in 162 schools in North and North East Indian states. Moreover, one school from Bhutan and another from Mandalay in Myanmar also participated in that drill. Last year in 2014 the turnout was phenomenal with participation of more than 725,000 children in 1100 schools.

Charles Brown (British engineer). Charles Brown (30 June 1827 – 6 October 1905) was a British industrialist, inventor and engineer. He founded the Swiss Locomotive and Machine Works (SLM), and was an engineer and executive of Sulzer and Maschinenfabrik Oerlikon.

Early life and education 
Brown was born 30 June 1827 in Uxbridge, England (presently a part of London), the oldest of five children, to Dr. Charles Brown, Sr. (1805–1873), a strictly religious dentist, and Jane Brown (née Morton; 1806–1873). His siblings were Sarah Ann (born 1830), Emma Jane (born 1834), John Henry (born 1836) and Archibald.

He was raised in the industrially shaped area of Woolwich. Between 1845 to 1851, Brown apprenticed to Maudslay, Sons and Field, becoming a mechanical engineer. The company was one of the leading steam engine manufacturers at the time. There he was introduced to Swiss Gottlieb Hirzel, a brother-in-law of Johann Jakob Sulzer, of the Sulzer family. Gottlieb was supposed to return to a position at Sulzer Brothers but declined and offered the position to Charles, who ultimately took the opportunity.

Career
In 1851, Brown relocated to Winterthur, Switzerland, to work for Sulzer Brothers as mechanical engineer responsible for machinery construction. At the time Sulzer was a  small to medium-sized company with about 100 employees. In 1871, he left Sulzer to set up Swiss Locomotive and Machine Works (SLM). While at SLM he invented the Brown valve gear, a radial valve gear for steam engines. He became involved in the development of electric locomotives in the 1880s. In 1885 he became manager of Maschinenfabrik Oerlikon and in 1890 he set up Charles Brown and Company at 91 Rione Amedeo, Naples, Italy.

Personal life
In 1862, Brown married Eugénie Pfau (1845–1927), a daughter of Jakob Pfau (1803–1882) and Friederike Pfau (née Sulzer; 1811–1856), who both hailed from well-established families in the city of Winterthur. They had six children;

 Charles Eugene Lancelot Brown (1863–1924), who co-founded Brown, Boveri & Cie., married Amelie Nathan (died 1914), a son and a daughter who later emigrated to the United States.
 Sidney William Brown (1865–1941), art collector and executive of Brown, Boveri & Cie, married Fanny Sulzer (1871–1968), three sons.
 Jane France Eugénie Brown (born 1866), married to a Mr. Müller.
 Ellen Kate Maude "Nelly" Brown (1867–1940), married to Dr. Carl Täuber.
 Alice Katharina Eugenie Brown (born 1868).
 Julie Fanny Ida "Juliet" Brown (1869–1943), married to Gustave Jacob Melms (1852–1943).

Brown died 6 October 1905 in Basel, Switzerland. Although being active in Switzerland for the majority of his adult life, Brown retained British nationality, and never naturalized.

Logic learning machine. Logic learning machine (LLM) is a machine learning method based on the generation of intelligible rules. LLM is an efficient implementation of the Switching Neural Network (SNN) paradigm, developed by Marco Muselli, Senior Researcher at the Italian National Research Council CNR-IEIIT in Genoa.

LLM has been employed in many different sectors, including the field of medicine (orthopedic patient classification, DNA micro-array analysis  and Clinical Decision Support Systems ), financial services and supply chain management.

History 
The Switching Neural Network approach was developed in the 1990s to overcome the drawbacks of the most commonly used machine learning methods. In particular, black box methods, such as multilayer perceptron and support vector machine, had good accuracy but could not provide deep insight into the studied phenomenon. On the other hand, decision trees were able to describe the phenomenon but often lacked accuracy. Switching Neural Networks made use of Boolean algebra to build sets of intelligible rules able to obtain very good performance. In 2014, an efficient version of Switching Neural Network was developed and implemented in the Rulex suite with the name Logic Learning Machine. Also, an LLM version devoted to regression problems was developed.

General 
Like other machine learning methods, LLM uses data to build a model able to perform a good forecast about future behaviors. LLM starts from a table including a target variable (output) and some inputs and generates a set of rules that return the output value  corresponding to a given configuration of inputs. A rule is written in the form:

if premise then consequence

where consequence contains the output value whereas premise includes one or more conditions on the inputs. According to the input type, conditions can have different forms:
 for categorical variables the input value must be in a given subset: .
 for ordered variables the condition is written as an inequality or an interval:  or 

A possible rule is therefore in the form

 if  AND  AND  then

Types 
According to the output type, different versions of the Logic Learning Machine have been developed:
 Logic Learning Machine for classification, when the output is a categorical variable, which can assume values in a finite set
 Logic Learning Machine for regression, when the output is an integer or real number.

Humber ware. Humber ware is a type of Medieval ceramic produced in North Yorkshire, England in the late 13th to early 16th Centuries AD.

Production zone
Two of the best known production sites are at West Cowick and Holme-on-Spalding-Moor, with some additional evidence for one in or near York as well as a kiln at Kelk.

Fabric
Humber wares are hard-fired, iron-rich usually red-bodied wares, although often with reduced cores. They are sparsely tempered with a fine sand, although there are examples of more gritty types.

Form and decoration
Forms include jugs of various sizes, cooking pots and (in the later phases of the industry) urinals and bung-hole cisterns. Several Humber ware sherds have a white encrusted deposit on the interior surface, which has been found to derive from urine. The glaze is usually olive or brownish green, sometimes forming a brown margin at the edges of the glaze. Decoration is usually limited to bands of horizontal grooving on the shoulders or neck, with occasional patterns of wavy combing, rouletting, or stamping. One of the best known products of the Humber kilns are the small drinking jugs, which replaces wooden bowls used in earlier times.

Industry
The Humber ware tradition last for a long time, from the late 13th to the early 16th Century AD, with a peak of production at some point in the 15th Century AD. Its gradual emergence is paralleled by a fall in popularity of the Brandsby-type ware industry. The dating of the end of the industry is not certain; different pottery types such as purple glazed ware and post-medieval red coarse ware seem to develop out of the Humber ware tradition. At the end of the 15th Century AD, the decline in coarse wares for items like cooking vessels may reflect the increased use of metal wares and may be the reason why metal forms were imitated by the potters.

Solo Wings. Solo Wings CC was a South African aircraft manufacturer based in Gillitts, KwaZulu-Natal. The company specialized in the design and manufacture of ultralight trikes in the form of ready-to-fly aircraft for the European Fédération Aéronautique Internationale microlight category.

The company seems to have gone out of business circa 2012 and production of its Solo Wings Aquilla design taken over by Microcrafts Africa.

The company produced two ultralight trike designs, starting with the entry-level Windlass, powered by the Rotax 503  twin cylinder, two-stroke, air-cooled aircraft engine in about 1987. More than 600 of this model had been delivered by 2001. In the 1990s the more sophisticated Aquilla was introduced.

Bateleur Sky Sports
Both Solo Wings models were sold in the United States by a Solo Wings distributor, Bateleur Sky Sports, Inc. of Palm Coast, Florida and later Fort Lauderdale, Florida from the late 1990s until the early 2000s under their own name as the Bateleur Windlass and Bateleur Aquilla. Bateleur Sky Sports appears to have gone out of business in about 2004.

Khaled al-Obaidi. Khaled Yassin al-Obaidi (born 1959) is an Iraqi politician who served as the defense minister of Iraq from 2014 to 2016.

Background
Khalid Yassin al-Obaidi is a Sunni Muslim who was born in Mosul. He belongs to the al-Obaidi Sunni tribal confederation. al-Obaidi is a member of the Iraqi parliament's Itihad al-Quwa al-Wataniyah bloc. He holds two master's degree in engineering and military science as well as a doctorate in political science. He served in the Iraqi Air Force, specialising in engineering aircraft engines until 2003 when he was appointed as a university professor by the Ministry of Higher Education. He was appointed as the Technical Education Authority by the Ministry of Education in 2007 and has also served as a security advisor for the President of the Parliament. He was nominated for the post of Defense Minister and accepted by the Prime Minister Nouri Al-Maliki in 2010 but was rejected by Ayad Allawi, the Iraqi National List founder. He was also a major general in the Iraqi Army.

Defence Minister 
On 18 October 2014, he was appointed as the Defence Minister of Iraq. In August 2016, al-Obeidi was voted out of power through a no-confidence vote in the parliament, with a majority of lawmakers voting against him over allegations of corruption. He is the first incumbent defence minister to receive a no-confidence vote in Iraq after the invasion of Iraq in 2003. Othman Ghanm was appointed to succeed him as the interim Defence Minister by the Iraqi government on 29 August 2016.

Later career

In December 2017 an MP reported that an arrest warrant had been issued for al-Obaidi. Warrants were issued for 48 defence officials in total, including the air force commander.

al-Obaidi later shifted to the Azem Alliance. Prime Minister Mustafa Al-Kadhimi appointed him as the head of the operations section of the Iraqi National Intelligence Service on 14 September 2020.
