Suicide of Kevin Whitrick. Kevin Neil Whitrick (17 August 1964 – 21 March 2007) was a British electrical engineer who committed suicide by hanging himself while in an online chat room.

Background 
Whitrick had been married to his wife Paula since 1988, and they had two children. At the time of his death, the marriage broke down about two years prior, and he was living separately from his family. In 2006, Whitrick was severely injured in a car accident and suffered long-term health consequences.

Suicide 
In March 2007, Whitrick was using the Paltalk video chat service, in a special "insult" chatroom with about 60 other users where people "have a go at each other". He stood on a chair, punched a hole in his ceiling and placed a rope around a joist, then tied the other end around his neck and stepped off the chair in order to asphyxiate himself. Some people thought this was a prank, until his face started turning blue. Some people in the chat room encouraged him by saying things like "just get on with it", while others tried desperately to find his address. A member in the room contacted the police, who arrived at the scene two minutes later. Whitrick was pronounced dead at 11:15 pm GMT.

Aftermath 
The death was widely reported in the media. Concerns were raised over the possibility that it could inspire further suicides, as well as the webcam footage becoming available in perpetuity on the internet. Detectives traced about 100 chatroom users to question them about their role in the suicide, though the Crown Prosecution Service did not pursue any criminal charges against them.

Institute for the Study of Violent Groups. The Institute for the Study of Violent Groups (ISVG) is a research institute focused on insurgency, terrorism, and transnational organized crime located at the University of New Haven in West Haven, Connecticut.

The organization's main mission is to aggregate, code, and analyze data. The organization claims to have built the largest and most comprehensive open-source database on violent extremism and transnational threats, which can be accessed via the DAVE Data Access and Visualization Environment (D.A.V.E. ISVG provides this open-source data and analysis to federal, state, and local law enforcement agencies in support of counter-terrorism.

History
ISVG was established in 2002 at Sam Houston State University in Texas by Dr. Richard Ward, then dean of the College of Criminal Justice, through a grant from the Bureau of Justice Assistance at the United States Department of Justice. ISVG was originally created to test the feasibility of using a relational database to identify trends, relationships, and tactics of terrorist groups using only open source information.

In 2008, Ward moved ISVG to the University of New Haven and began distributing its data collection efforts. In 2011, the ISVG launched its Violent Extremism Knowledge Base (VKB). The same year, it announced the Homeland Security Open Source Solution (HSOSS) with i2 Group, Inc.

The original staff consisted of seven data collectors. Currently, ISVG has more than 90 personnel involved in collecting and analyzing open source information.

MERODE. MERODE is an Object Oriented Enterprise Modeling method developed at KU Leuven (Belgium). Its name is the abbreviation of Model driven, Existence dependency Relation, Object oriented DEvelopment. MERODE is a method for creating domain models (also called conceptual models) as basis for building information systems making use of two prominent UML diagramming techniques - class diagram and state diagrams. Starting from a high-level PIM (close to a Computational Independent Model (CIM)) allows removing or hiding details irrelevant for a conceptual modelling view which makes the approach easier to understand. 
The method is grounded in process algebra, which enables mathematical reasoning on models. Thanks to this, models can be checked for internal consistency and mutual completeness, i.e. inter/intra model consistency and syntactical quality. The automated reasoning ("consistency by construction")  also caters for autocomplete functionality, which allows creating correct models faster.

A typical MERODE analysis or conceptualisation consists of three views or diagrams: a so-called existence dependency graph (EDG) similar to a UML class diagram, a proprietary concept namely an object event table (OET) and a group of finite state machines.

MERODE fosters a model-driven engineering approach to software development. It targets platform independent domain models that are sufficiently complete for execution, i.e. transformation to platform-specific models and to code. In order to achieve automated transformation of models, MERODE limits the use of UML to a number of well-defined constructs with clear semantics and complements this with the notion of "existence dependency"  and a proprietary approach to object interaction modelling.

MERODE-models can be created with the opensource case tool JMermaid. The tool also allows checking the models for consistency and readiness for transformation.

A companion code generator allows to generate a fully working prototype. One-click prototype production lowers the required skill-set for its useful application. By embedding the models into the application, the behaviour of the prototype can be traced back to the models, i.e. making it possible to validate the semantic quality of models. MERODE prototypes are augmented with feedback (textual and graphical)  that links the test results to their causes in the model.

Twofer. A twofer is a cabling device used in theatrical stage lighting. It allows two stage lighting instruments to be connected to one circuit. It is wired in parallel, such that voltage is unchanged in the twofer, and current is split and divided over two connectors. Twofers are used in conjunction with cables with the same types of connectors.
The name is a corruption of the phrase "Two For One".

UK terminology
The UK equivalent of the twofer is a Grelco. The name derives from the manufacturer of the original examples, but is now generally adopted for all examples regardless of manufacturer. It typically relates to a splitter for the UK 15 A power connections commonly used for stage lighting. It is usually an integral block rather than a plug with two cables leading to two sockets. Where a single plug goes to three or more sockets it is sometimes known as a Trelco.

Typically for most other power connector types used in theatre, the term (2-way) splitter is used.

Australian terminology
For several decades, much rock-and-roll and other lighting used "Par Cans", each containing a 120-volt PAR 64 lamp. As the mains supply is 240 volts these must be connected in series, via an adapter lead or box featuring two sockets.

TacSat-1. TacSat-1 was an experimental satellite built by the Naval Research Laboratory (NRL) on behalf of the United States Department of Defense (DoD) Office of Force Transformation (OFT). It was the planned payload of the sixth launch of the SpaceX Falcon 1. It was however never launched into space. The second satellite in the series, TacSat-2, launched before TacSat-1 and this led to the cancellation of TacSat-1's launch.

TacSat-1 would have carried a variety of experimental payloads. Much of the payload software was implemented through the use of bash scripts operating on the "Copperfield-2" general-purpose computer system aboard the spacecraft.

Purpose 
The TacSat series of experimental spacecraft are designed to allow military commanders on a battlefield to request and obtain imagery and other data from a satellite as it passes overhead. Collected data will be delivered to field commanders in minutes rather than hours or days. The sensor on TacSat-1 could collect color images sharp enough to distinguish ground objects as small as 1 meter in diameter.

Launch 
TacSat-1 was initially planned for launch in January 2004, but delays in Falcon 1 becoming operational precluded this date. It was initially scheduled to fly on the maiden flight of the Falcon 1, but technical problems led to another Falcon 1, with FalconSat-2, launching first. Following the failure of this launch, it was moved to the third flight, to allow a demonstration launch to precede it. The failure of the demonstration flight led to further delays. In August 2007, the Pentagon announced that the launch of TacSat-1 was canceled due to the completion of most of its mission requirements by AFRL's previously launched TacSat-2. In September 2008, this decision was reversed, and it was reported that TacSat-1 would be launched by the sixth Falcon 1, in 2009, and be called TacSat-1A. This revamped mission was later cancelled again when TacSat-2 proved all the things TacSat-1 was supposed to.

Systems 
The TacSat series of satellites use commercial or available launchers, and largely off-the-shelf components, in order to reduce costs.

Satellite bus 
The TacSat-1 spacecraft was based on Orbital Sciences Corporation (OSC) MicroStar (triple) satellite bus, also used for the Orbcomm communications constellation. TacSat-1 inherited its avionic bus from an unlaunched Orbcomm-satellite.

Developers 
Apart from the Naval Research Laboratory (NRL), other organizations participating included: 
 DoD Space Test Program (Space and Missile Systems Center's Space Development and Test Wing)
 DoD Operationally Responsive Space Office
 Army Space Program Office
 Air Force Space Command
 Space Innovation and Development Center

Rice Institute Computer. The Rice Institute Computer, also known as the Rice Computer or R1, was a 54-bit tagged architecture digital computer built during 1958–1961 (partially operational beginning in 1959) on the campus of Rice University, Houston, Texas, United States. Operating as Rice's primary computer until the middle 1960s, the Rice Institute Computer was decommissioned in 1971. The system initially used vacuum tubes and semiconductor diodes for its logic circuits; some later peripherals were built in solid-state emitter-coupled logic.  It was designed by Martin H. Graham.
A copy of the machine called OSAGE was built and operated at the University of Oklahoma.

Memory
Memory was implemented using a variety of technologies over the lifetime of the R1.  Originally a cathode ray tube or "Williams tube" array, RCA core memory was introduced in 1966, followed by Ampex core memory in 1967. Following those two upgrades, the R1 had reached its full 32k word capacity, although the original electrostatic memory was soon decommissioned due to falling reliability in its old age.

Architecture
The R1 had seven memory-mapped general-purpose processor registers, each 54 bits in size, in addition to a constant zero register. For memory addressing, seven  16-bit "B-Registers" were used. The program counter was also held in a writable "B-Register". See the table below for conventions and hardware-enforced usage of these registers.

Hydrokenoelsmoreite. Hydrokenoelsmoreite is a hydrous tungsten oxide mineral with formula □2W2O6(H2O). Hydrokenoelsmoreite is a colorless to white, translucent isometric mineral. It has a Mohs hardness of 3, exhibits no cleavage and has a splintery fracture. It has a vitreous to adamantine luster. It is optically isotropic with an index of refraction of n = 2.24.

It forms from the oxidation of ferberite within granitic pegmatite dykes and in pegmatitic greisen veins. It has a structure based on a defect pyrochlore lattice (A2B2O6O’).

It was first described for an occurrence in Elsmore Hill, New South Wales, Australia from where it takes its name.

Miles Monarch. The Miles M.17 Monarch was a British, light, touring aeroplane of the 1930s. It was a single-engine, three-seat, cabin monoplane with a fixed, tailwheel undercarriage.

Development
The last civil type produced by Phillips and Powis before the war, the Monarch was a development of their earlier Whitney Straight. Compared to its sibling. the Monarch had an enlarged fuselage, allowing provision of a third seat in part of what had been the luggage space.

Operational history
Eleven aircraft were built between 1938 and 1939, six of these to British customers, the rest going to export.

On the outbreak of war five of the British-registered machines were impressed by the Air Ministry; one machine belonging to Rolls-Royce acquired camouflage paint but remained in its owner's service. All but one of these survived the war, though a Dutch-registered aeroplane (PH-ATP) was destroyed in the Luftwaffe raid on Schiphol on 10 May 1940. One aircraft, OY-DIO, was on the Danish register until 9 Sept. 1939 and owned by a Dane named Hagedorn.

In the 1950s, one Monarch (G-AIDE) enjoyed some success as a racer in the hands of W.P. Bowles

For the most part, the remaining Monarchs led uneventful but useful careers; a number survived into the Sixties.  G-AFJU is displayed at the National Museum of Flight at RAF East Fortune near East Linton, Scotland.

Steckel mill. A Steckel mill is also known as a reversible finishing mill, is similar to a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill, therefore the process is more similar to drawing than rolling. The material is fed back and forth through the mill until the desired thickness is reached, much like a reversing rolling mill.

It is also used to process steel slabs into hot rolled coil. The Steckel mill allows the rolling of a large slab by providing heated reels on both sides of the mill to store the increased length produced during rolling. These drums allow for additional heat retention and thermal consistency in the rolled piece, which in turn produces improved uniformity throughout the rolled product. A furnace is provided in both sides of the mill, which covers the mandrels each in one side upon which the slab is rolled after every complete pass. Output from Steckel mill varies from 1 to 2 mm. A cutter mechanism is also provided in this mill to cut the irregular head and tail of the incoming slab.

In the Steckel mill, several passes have to be taken to get the desired reduction. The Steckel mill has quality problems due to temperature losses. The rate of production in a Steckel mill is lower than a tandem mill.

China Railways 6K. The 6K is a Japanese-built electric locomotive used in China. It is developed and built by Kawasaki Heavy Industries and Mitsubishi Electric. The design of 6K is based on JNR Class ED75 and EF66 electric locomotives. It is the first locomotive with Bo-Bo-Bo wheel arrangement used in China.

Production
In total 85 6Ks were built between 1986 and 1987.

Equipment
Each 6K locomotive uses CLG-616 phase splitter and 6 Mitsubishi Electric MB-530-AVR DC traction motors.

Performance
6K was one of the most reliable electric locomotives in China compared with SS1, SS2 and SS3 at the time of entering service.  China later made SS7 locomotive with reference to the Tri-Bo wheel arrangement of 6K, the breakdown rate, however, was still high, until its modified version SS7B, SS7C and SS7D designed.
