Numerical Wind Tunnel. Numerical Wind Tunnel (数値風洞) was an early implementation of the vector parallel architecture developed in a joint project between National Aerospace Laboratory of Japan and Fujitsu. It was the first supercomputer with a sustained performance of close to 100 Gflop/s for a wide range of fluid dynamics application programs. It stood out at the top of the TOP500 during 1993-1996. With 140 cores, the Numerical Wind Tunnel reached a Rmax of 124.0 GFlop/s and a Rpeak of 235.8 GFlop/s in November 1993.

It consisted of parallel connected 166 vector processors with a gate delay as low as 60 ps in the Ga-As chips. The resulting cycle time was 9.5 ns. The processor had four independent pipelines each capable of executing two Multiply-Add instructions in parallel resulting in a peak speed of 1.7 Gflop/s per processor. Each processor board was equipped with 256 Megabytes of central memory.

Wilhelm Christian Suhrke. Wilhelm Christian Suhrke (2 November 1863 – 10 May 1950) was a Norwegian architect and politician for the Conservative Party.

Biography
He was born in Fredrikshald (now Halden) in Østfold, Norway. He was a son of German-born architect Ernst Suhrke (1829-1892) and his wife Barthe Svendsen (1837-1923). Suhrke graduated in engineering during 1882 from Trondhjems Tekniske Læreanstalt  (now Norwegian University of Science and Technology) at Trondheim and studied at the Polytechnical School of Hannover (now Leibniz University Hannover) from 1884 to 1886. He joined his father in 1884 and from 1892 he directed the firm. He is known for designing buildings such as Halden Arbeidersamfund, Tordenskjolds 3, Halden Bad and his own residence Suhrkevillaen on Rødsberget in Halden. His later works are characterized by functionalism.

Suhrke served as vice consul for Germany from 1901. He was elected to Fredrikshald city council in 1892, and served for many years, including an unknown period as deputy mayor. He served as a member of the Parliament of Norway from 1904 to 1906 and 1910 to 1912.

Together with Ursula Lorange (1867–1933) he had two daughters.  Inger Lorange Suhrke (1898-1982) who married  diplomat Finn Støren. Else Lorange Suhrke (1902-1960)  married Kaare Heiberg (1896-1978), son of railway director Eivind Heiberg.

Dilidam. Dilidam is a multimedia and passenger information system which provides route information to passengers on the RATP mass-transit system in Paris, France.  The project was in a trial phase in Autumn 2005 and is now in regular use on several bus and metro lines in the region.

Principles 

The system consists of 17-inch LCD screens which display realtime information regarding the route, such as the next stops, schedules of connecting routes, and maps of the current area. In addition to this information, the system also provides more general information such as news bulletins, reports, video clips, announcements, and advertisements.

On buses, the system uses GPS in order to locate the vehicle. In addition, buses communicate directly with bus stops along the route via radio waves to apprise those waiting at the stop of the wait before the next bus will arrive.

Deployment 

In 2006 and 2007, the system was tested on line 38 of the RATP bus system as well as MP 89-model trains on line 1 of the Paris Métro. This trial ended in 2007.

Currently, the system can be found in an MF 2000 prototype train (train MF 01 001) which circulates Paris Métro line 2. The first production units to feature the system are the MP 05 trains deployed on Paris Métro Line 1 in 2012. Each of these trains are equipped with 4 screens per car.

Technical specifications 

In the version of the system currently being used in the MF 2000 train, the Dilidam system functions with the help of two computers running Windows XP Embedded.  Each computer manages one half of the screens in the car.

Port of Nacala. The Port of Nacala, also called the Nacala port complex, is a Mozambican port located in the cities of Nacala and Nacala-a-Velha. Is the deepest port in Southern Africa. The natural deep harbour serves landlocked Malawi with a  railway.

The infrastructure belongs to the Mozambican government, which is responsible for its administration through the public-private joint venture company "Integrated Northern Logistical Corridor Society" (CLIN). CLIN was created to administer licenses for cargo terminals in addition to passenger terminals.

Terminals 
There are four general cargo berths and one container berth. In January 2016 a coal terminal was completed in the town of Nacala-a-Velha, across the bay from the commercial port, and exports coal from the Moatize mine in western Mozambique.

Railway 
The Nacala railway system connects Moatize and Chipata, Zambia, through Malawi with the Port of Nacala. The railway system also connects Nampula, Malema, and Cuamba. In Cuamba, there is a junction which goes northeast to Lichinga. The line continues to Nayuchi, where it enters Malawi, and to Nkaya, where it divides, one branch going west to Mchinji and Chipata, and the other branch south to Moatize. The Mozambique government and Vale jointly created the Integrated Northern Logistical Corridor Society, to rehabilitate most of the existing line and build greenfield sections, a work completed in 2017, to export coal from mines in western Mozambique.

Countries served 
  Northern areas of the Mozambique
  The country of Malawi: the Port of Nacala is the nearest port to the landlocked country
  A railway extension serves parts of Zambia, in particular the inland port of Chipata

Flight Laboratory, IIT Kanpur. Flight Laboratory, IIT Kanpur is an airstrip/aerodrome located inside IIT Kanpur's campus at Kalyanpur 18 kilometres west of city of Kanpur, India. It is used by the Aerospace Engineering department of IIT Kanpur. Pawan Hans began a helicopter ferry service to Lucknow from June 2013, which later shut down silently.

History
IIT Kanpur received collaborative technical assistance from a consortium of nine leading US universities when it was being set up. Considering the intense research potentials and rapid growth in the field of aviation at that time, it was decided to establish the faculty of Aeronautical Engineering at IIT Kanpur. Under the USAID educational assistance project, an all-weather 884x61 m small airstrip was set up with a Flight Laboratory. The Lab was equipped with Piper PA-18 and Cessna 182 powered aircraft and Schweizer 2-22 and Schweizer 1-26 gliders. A Rohini glider, designed and developed at Technical Center of Civil Aviation Department and manufactured at HAL, was the jewel in the crown of the Flight Lab. The open cockpit, side-by-side seating, fabric covered wooden structure glider became very popular among students and used extensively for research work. Soon the Flight Lab. swung into action and the gliders were aero-towed to desired heights with students on board for the complex studies of aerodynamics and flight mechanics.

The glider flying programme was an instant hit with the students of IIT Kanpur. Due to the massive response, membership was restricted to a number of selected students. You could see them beeline for the Center immediately after their classes. The intense heat of summer or the extreme cold of winter could not deter them from that one more flight. The excitement of positive- and negative- 'G's, long soaring flights or a first solo provided a special thrill and were keenly awaited. Soaring flights of over five hours and altitudes over 10,000 feet became common events. Many students who were unable to become members became frequent visitors for joyrides. The campus residents were not to be left far behind, and visited the centre with family and friends to lose the feel of being earth-bound.

Eurocode 4: Design of composite steel and concrete structures. In the Eurocode series of European standards (EN) related to construction, Eurocode 4: Design of composite steel and concrete structures (abbreviated EN 1994 or, informally, EC 4) describes how to design of composite structures, using the limit state design philosophy.  It was approved by the European Committee for Standardization (CEN) on 4 November 2004. Eurocode 4 is divided in two parts EN 1994-1 and EN 1994-2.

Eurocode 4 is intended to be used in conjunction with:

 EN 1990: Eurocode - Basis of structural design;
 EN 1991: Eurocode 1 - Actions on structures;
ENs, hENs, ETAGs and ETAs for construction products relevant for composite structures;
 EN 1090: Execution of steel structures and aluminium structures;
 EN 13670: Execution of concrete structures;
 EN 1992: Eurocode 2 - Design of concrete structures;
 EN 1993: Eurocode 3 - Design of steel structures;
 EN 1997: Eurocode 7 - Geotechnical design;
 EN 1998: Eurocode 8 - Design of structures for earthquake resistance, when composite structures are built in seismic regions.

Part 1-1: General rules and rules for buildings
EN 1994-1-1 gives a general basis for the design of composite structures together with specific rules for buildings.

Actor (programming language). The Actor programming language was invented by Charles Duff of The Whitewater Group in 1988. It was an offshoot of some object-oriented extensions to the Forth language he had been working on.

Actor is a pure object-oriented language in the style of Smalltalk. Like Smalltalk, everything is an object, including small integers. A Baker semi-space garbage collector is used, along with (in memory-constrained Windows 2.1 days) a software virtual memory system that swaps objects. A token threaded interpreter, written in 16-bit x86 assembly language, executes compiled code.

Actor only was released for Microsoft Windows 2.1 and 3.0. Actor used a pure object-oriented framework over native operating system calls as its basic GUI architecture. This allows an Actor application to look and feel exactly like a Windows application written in C, but with all the advantages of an interactive Smalltalk-like development environment. Both a downside and upside to this architecture is a tight coupling to the Windows architecture, with a thin abstraction layer into objects. This allows direct use of the rich Windows OS API, but also makes it nearly impossible to support any other OS without a significant rewrite of the application framework.

A demo of Actor was shown in an episode of Computer Chronicles.

Tessellated roof. Tessellated roof is a frame and a self-supporting structural system in architecture. A simple ridged roof may inside be a tessellated system. The interlinking shapes are replicated across the moulded surface using curvilinear coordinates, a specific technique with rigid interlinking beams, having characteristics similar to woven fabric. A tessellated roof is one of the most flexible framed systems to design. The measurements and precision are complex and commonly part of a computer-aided design process of production. It is used in a honeycomb geometry form, in the biomes of the Eden Project.

It can be fabricated to fit a wide range of situations. The size of the repeated geometric shape used can be customised, with a multitude of the same shape throughout the structure. An even and equal load is shared by the interlocking structural integrity of the frame as a whole. The use of a tessellated roof for public areas is an increasingly implemented architectural feature of modern public buildings, covering walkways and over retail centers. A transparent roof being for shelter from the weather, has an advantage during daylight with electricity for artificial lighting in solid roof buildings being a financial cost.

A modern tessellated roof for roofing public areas is a variation of a greenhouse or glass roof in different shapes and sized. The roof can be held aloft with columns, that may have branches to support and connect to the roof latticework, which stabilise the roof to create a strong structure. The material of the roof in-between or covering the tessellated frame may be a light composite, toughened glass or insulated glazing. There are roofed boulevards with columns that can form a colonnade. Some tessellated roof shapes connect to the ground in place of conventional rain gutters, for example the FieraMilano, or it can be supported entirely by the surrounding buildings. A tessellated roof can convert previous outdoor space into a dry public area; some examples of this method are Galleria Vittorio Emanuele II and many other shopping complexes or the Queen Elizabeth II Great Court at the British Museum in London by Norman Foster.

Exeter Power Station. Exeter Power Station (also known as Haven Road Power Station) is a former coal-fired power station on the River Exe quayside, Exeter, England.

History
Electricity demand in Exeter increased with introduction of an electric tram system. The City of Exeter Electricity Company's existing power station on New North Road needed replacing. In 1899, a hydroelectric plant at Trews Weir was proposed, but there were fears that this would affect the Exeter Ship Canal and the plans were shelved. Instead the coal-fired power station was built on a  square at Haven Banks.

The station was constructed by W Brealey of Exeter. It was of brick construction and contained a boiler room, engine room, offices, an annexe for economisers, and a  tall chimney at one end. The boiler room measured  by  and was lined with glazed bricks and had a terrazzo marble floor. Boilers were provided by Babcock & Wilcox and steam engines by Belliss and Morcom. British Westinghouse Electric Manufacturing Company generating equipment was also installed. Coal feed equipment and additional iron work was designed and built by Willey's, and cabling from the station throughout the city was provided by the Siemens Brothers of London.

Initially the station used the old boilers and generating equipment of the New North Road power station, alongside four new sets of steam driven alternators. With the equipment removed, the electric company sold the New North Road station in 1906. The Haven Road power station was opened in 1905 by Mayor Cllr Perry.

Operations
Coal was delivered to the station by rail and ship. Once delivered to the station it was fed automatically onto a gravity bucket conveyor system which supplied 500 tonne capacity bunkers. These discharged onto mechanical stokers and into the boiler furnace. Ash was removed automatically.

Expansion and later history
The station was part of an expansion of the City of Exeter Electricity Company, with Heavitree being added to the Exeter grid in 1906. Further expansion occurred in 1923, with the addition of Topsham, Pinhoe, Alphington and Ide, and in 1932, with the addition of Kenn, Shillingford St. George and Dunchideock, all supplied by the Haven Road station. Between 1927 and 1930, the station's generating capacity was increased from 4,000 kilowatts (kW) to 15,350 kW to meet the extra demand. Between 1900 and 1930, the number of electricity customers in Exeter grew from 350 to 18,463. In 1936 this figure grew to 19,000 customers, supplied through  of cables to an area of . They also supplied electricity to the Exe Valley and East Devon electricity companies.

The station was closed in 1955. After it closed the building was used for a time as a depot for the South Western Electricity Board, and after that as a maritime museum. It is now one of few surviving pre-nationalisation power stations. In 2011, the main turbine hall was converted to house an indoor climbing centre.
