NetExpert. NetExpert monitors and controls networks and service impacting resources using object-oriented and expert systems technologies.

Background 
NetExpert is considered an OSS, used in managing wireline and wireless networks and services.

NetExpert is a scalable and distributable architecture that supports flexible configuration while maintaining individual component independence. Its application packages address many areas of communication services management, including fault, performance, reporting, activation, IP services, and others. These can be further tailored to individual customer environments and management requirements.

This framework consists of a set of integrated software modules and graphical user interface (GUI) development tools to enable the creation and deployment of complex management solutions. The object-oriented architecture of the NetExpert framework provides the building blocks to implement operations support and management systems using high-level tools rather than low-level programming languages.

The NetExpert framework is founded on open systems and object-oriented methodology.  NetExpert supports different standards, transmission protocols, and equipment data models.  NetExpert is based on the Telecommunications Management Network architecture created by the Telecommunications Standardization Sector of the International Telecommunication Union.  It supports the development and deployment of applications for the main TMN management areas—fault, configuration, accounting, performance, and security—and the implementation of layered management architectures.  In addition, the NetExpert framework employs expert rules and policies that replace complex programming languages and enable network analysts to model desired system behaviors by using GUI-based rule editors.

Pratt's Mill, Crowborough. Pratt's Mill is a  tower mill at Crowborough, Sussex, England which has been truncated and converted to residential accommodation.

History

Pratt's Mill was built between September 1861 and February 1862. The machinery from Calverley Mill, Tunbridge Wells was used in the construction of the mill. On 3 February 1862 the son of the miller was killed when he became entangled in the machinery. The mill was working by wind until 1907 and then by steam until 1922. Frank Brangwyn, RA painted the mill when it was without sails and fantail. The picture appears in an early book on windmills. In 1927 the mill was converted into residential accommodation, being reduced in height to three storeys.

Description

As built, Pratt's Mill was a five-storey brick tower mill clad in  peg tiles. It had four Patent sails and the Kentish-style cap was winded by a fantail. All that remains today is the lower three storeys of the tower, with various additions and extensions. Hemming states that the mill may have driven three pairs of millstones.

Walter's Mill, Mark Cross. Walter's Mill is a  tower mill at Mark Cross, Sussex, England which has been converted to residential accommodation.

History

Walter's Mill was first mentioned in 1845 and is thought to have been built by the Arnold brothers of Paddock Wood, Kent. The mill was working by wind until 26 July 1911, when it was burnt out. The mill was refitted and driven by a gas engine, at that time having a crenellated top, which was removed in the early 1930s. the mill building was converted and extended to form a house in 1962. In 2005, it was announced that the owners planned to rebuild the cap and sails, and return the mill to a more traditional appearance in the long term.

Description

Walter's Mill is a five-storey tile-hung brick tower mill. It had four Patent sails. The Kentish-style cap was winded by a fantail.  The mill drove two pairs of underdrift millstones. The converted tower stands today, with the window and door openings having been enlarged during the conversion.

DemoSat. A DemoSat is a boilerplate spacecraft used to test a carrier rocket without risking a real satellite on the launch. They are most commonly flown on the maiden flights of rockets, but have also been flown on return-to-flight missions after launch failures. Defunct satellites from cancelled programmes may be flown as DemoSats, for example the maiden flight of the Soyuz-2 rocket placed an obsolete Zenit-8 satellite onto a sub-orbital trajectory in order to test the rocket's performance.

Power trowel. A power trowel (also known as a "power float" and "troweling machine") is a piece of light construction equipment used by construction companies and contractors to apply a smooth finish to concrete slabs.

Types
Power trowels differ in the way they are controlled:
Ride-on power trowels have two spider/rotor assemblies and are controlled by an operator sitting on a seat upon the machine, controlling the power trowel movement with two joystick/levers (these can be either mechanical or electronic/hydraulic). Blade pitch is controlled either by manual turn handles, (usually both spiders are linked together) or by electric motors and switches.  Ride on power trowels range in size from  machines weighing , up to  machines weighing over . Power ranges from small  single cylinder engines, all the way up to  multi fuel V8 engines. Drive systems come in two basic variations direct mechanical drive (typically using a CVT style clutch) and hydrostatic drive. Additionally, they are available in overlapping and non-overlapping configurations, the latter allowing the use of float pans.
Walk-behind power trowels are used by an operator walking behind the machine.

A power trowel performs the tasks of several hand tools, hand trowel, hand float, darby and concrete float.

CEMEC. The Centre d'études de moteurs à explosion et à combustion (Explosion and Combustion Engines Studies Center) (CEMEC) was a company that continued the construction of BMW motorcycles taken from the German occupying forces after the Second World War. It was founded in 1945 as the Centre de montage et de récupération (CMCR) () at Neuilly-sur-Seine.  It was renamed CEMEC in 1947. 

It rebuilt BMW motorcycles, and for this reason, the logo is a modified version of the BMW logo, showing the colours of the French flag. 

CEMEC began to manufacture complete motorcycles, producing models derived from BMW designs for the French administration. The company constructed models made up of various German components, creating a hybrid of the R71 and R75 models, under the name R73.

In 1954, CEMEC was taken over by Ratier.

Light reflectance value. In architecture, light reflectance value (LRV), is a measure of visible and usable light that is reflected from a surface when illuminated by a light source.  The measurement is most commonly used by design professionals, such as architectural color consultants, architects, environmental graphic designers and interior designers.

LRVs are frequently reported on paint chips or paint samples. The values are used by lighting designers to determine the number and type of light fixtures needed to provide proper lighting for interior spaces.

Guidance
Designers of buildings must comply with the building codes applicable to the structure under consideration.  Since 2004 guidance has existed on access to and use of buildings.  The guidance is particularly concerned with provisions to assist the disabled, including those who are visually impaired. The guidance highlights the need for certain surfaces and features to contrast visually with their surroundings.  Areas of particular interest are wall-to-ceiling and wall-to-floor junctions, exposed edges of sloping floors, seating and its surroundings, leading edges of doors, door opening furniture and door surfaces, sanitary fittings and grab bars.

This is relevant to a wide range of non-residential buildings, such as hospitals, schools, hotels, and theatres.

Codes of practice
The British Standards Institute's guidance in the Regulations and in the relevant Codes of Practice, BS 8300:2018, is that adequate visual contrast is provided if the light reflectance values of the contrasting areas differ by at least thirty points.  The current British Standard for the measurement of LRV is BS8493:2008+A1:2010.

The Americans with Disabilities Act Standards for Accessible Design does not recommend a light reflectance value for contrast on signage with words or pictograms, but instead it provides that "characters shall contrast with their background with either light characters on a dark background or dark characters on a light background" in § 703.5.1 

The International Code Council utilizes the ADA approach and does not use a light reflectance value in the 2017 update to the standards for ICC A117.1 in § 703.5.3.2 

The United Nations Economic Commission for Europe uses a difference of sixty points between the LRVs for the contrast requirement of signage in "Railway Applications — Design for PRM Use - General Requirements — Part 1: Contrast."

Manufacturers are advised by the Guild of Architectural Ironmongery to publish the LRV for their products.

OPCON CCIS. OPCON, or more fully the Operational Control Command Control and Information System (OPCON CCIS) was a long term computer project run by the Ministry of Defence in the United Kingdom.

History
It started to be developed in 1974, and was initially used operationally as a proof of concept (OPCON PILOT) system for the Royal Navy during Operation Corporate (the Falklands War), and evolved into a wider, "Joint" use when declared Operational in 1986.

Technology
The original role of OPCON CCIS was envisaged as providing an automated message handling system and database for use by Commander-in-Chief Fleet (CINCFLEET) headquarters at Northwood. 

The solution was largely based on commercial ADP equipment, supplied by ICL, and the capital cost of the equipment was stated in 1989 to be of the order of £40 million.
