NER 901 Class. The NER 901 Class was a class of  steam locomotive of the North Eastern Railway, designed by Edward Fletcher. Between 1872 and 1882 55 of the class were built for the NER.

History
From their introduction, the 901 Class were used on the Newcastle-Edinburgh and Newcastle-York runs, hauling  loads. During 1884, engines based at Gateshead depot averaged  per month. Apart from minor instances of updating, only two of the class underwent extensive rebuilding. More substantial modifications were made to the last of the Neilson-built engines, No. 933, which, in 1907, was not only reboilered but converted into a . She was scrapped in 1914, one of 29 of the class withdrawn between 1913 and 1914. But for the onset of the first World War, the rest of the class would have followed suit. Instead the curtailing of new construction led to a shortage of motive power and new work was found for the 901 Class. Some were drafted on to the coastal line between Scarborough and Bridlington but the majority were stationed at Darlington. From here they worked passenger services over the Stainmore route to Kirkby Stephen, Penrith and Tebay. Darlington also kept them on as pilots.

By 1923 only ten of the class remained and the now preserved No.910 was amongst the final five to be withdrawn from service. 910 was displayed by the NER when new at the 50th anniversary of Steam on the Stockton and Darlington railway in 1875, by the LNER at the 100th anniversary in 1925, and again by British Railways at the 150th anniversary in 1975.

Accidents and incidents

On 25 March 1877, locomotive No. 901 was hauling an express passenger train which was derailed at , Northumberland due to excessive speed on a curve. Five people were killed and seventeen were injured.
On 4 October 1894, locomotive No. 904 was one of two locomotives hauling a sleeping car train which overran signals and collided with a freight train that was being shunted at Castle Hills, Yorkshire. One person was killed.

Preservation
Number 910 is preserved by the National Railway Museum. It was moved to the Stainmore Railway Company at Kirkby Stephen East station in 2011 for the Stainmore 150 celebrations, and remains there on loan, housed in the Darlington train shed of the main station building.

Petrel (reservoir software). Petrel is a software platform by Schlumberger Information Solutions used in the exploration and production sector of the petroleum industry. It is a cloud-based platform designed to develop collaborative workflows to increase oil and gas performance. It uses Esri's projection engine for CRS management and is compatible with ArcGIS files. Functionality within Petrel includes: interpreting seismic data, performing well correlation, building reservoir models, visualizing reservoir simulation results, calculating volumes, producing maps, and designing development strategies to maximize reservoir exploitation.

Background 

Petrel software was developed in Norway by a company called Technoguide. Technoguide was formed in 1996 by former employees of Geomatic, some of whom were key programmers involved in the early development of RMS.  Technoguide made 3D geologic modeling more accessible to all subsurface technical staff, including those without specialist training. Developed for PCs and the Windows OS, Petrel was commercially available in 1998. The Petrel user interface has a pre-arranged workflow to facilitate its use.  

In 2002, Schlumberger acquired Technoguide and the Petrel software tools.  Schlumberger currently supports and markets Petrel. Newer versions of Petrel include additional functionality such as geological modeling, seismic interpretation, uncertainty analysis, well planning, and links to reservoir simulators.

Essential unified process. The essential unified process for software development, or EssUP, was invented by Ivar Jacobson as an improvement on the rational unified process. It identifies practices, such as use cases, iterative development, architecture driven development, team practices and process practices, which are borrowed from RUP, CMMI and agile development. The idea is that you can pick those practices that are applicable to your situation and combine them into your own process. This is considered an improvement with respect to RUP, because with RUP the practices are all intertwined and cannot be taken in isolation.

EssUP is supported by a set of playing cards, each card describing a practice. This is because Ivar Jacobson believes that people buy his books but few read them.

It is announced that EssUP will be supported both by the IBM Rational toolset, Eclipse and Microsoft's Visual Studio.

Eccentric-hub scooter. An eccentric-hub scooter is a two-wheeled human powered vehicle with an off centered hub on the large rear wheel. The scooter is powered by the rider making a bouncing motion on the platform.

Description

An eccentric-hub scooter is similar to a kick scooter, but with a large rear wheel, mounted off-centre. It is propelled by the user bouncing up and down or rocking backwards and forwards on the platform to drive the rear wheel around the eccentric hub. One early inventor described the vehicle as a 'galloping scooter' and the rider's motion does resemble a horse-rider's motion. Although the motion produced is impact-free, it is reportedly less efficient than a conventional bicycle and will not propel the vehicle uphill.

History

Exercycle / Ingo-Bike

Although several patents for eccentric-hub cycles exist from 1928, the most popular incarnation was patented in 1934 by brothers Phillip and Prescott Huyssen and called the "Exercycle". It was produced by the Ingersoll Steel & Disc Co. (a division of Borg-Warner Corp.), from 1934 to 1937, under the name "Ingo-bike".  A large number of publicity events and promotions popularised the bike and a group of Ingo-bikers in the late 1930s traveled from Chicago to Miami in 30 days. Production ceased when the factory re-tooled to begin producing armaments prior to the Second World War. Phillip Huyssen continued designing variations until at least the 1970s. In the Three Stooges movie Yes, We Have No Bonanza, Curly rides up to a saloon bar on an Ingo-Bike.

Kangaroo Scooter
Apparently re-introduced as a children's scooter in the 1960s with the name "kangaroo scooter", kangaroo scooters were built in Taiwan for a company based in Concord, California. They had the eccentric rear wheel and a front caliper brake, chrome fenders, and a kickstand.

Another device, also called the Kangaroo Scooter, has been designed and sold by Ron and Johnny Knox's company, Knoxcooter Inc., of Weyburn, Canada since 2004. This variant includes a one-sided rear wheel support, disk brakes and uniquely a clutched rear hub; which allows the user to coast for periods without bouncing up and down. Contrary to popular belief, the Eco-Fav (Frequency Accelerated Velocipede) scooter is efficient enough to ride uphill; many users prefer to ride it on an incline to increase their workout resistance.

Bounce Bike
A similar concept is the 'Bounce-Bike' which has an eccentric front wheel and a small rear wheel.

Whymcycle
Peter Wagner has produced variants called "whymcycles" since the 1990s.  The name is derived from the word 'whimsical.'  Several dozen units of various configuration have been produced.

Arado Ar 195. The Arado Ar 195 was a single-engine prototype carrier-based torpedo bomber, built by the German firm Arado for service on the , during World War II.

Design and development
A derivative of the Ar 95, fitted with an arrestor hook and catapult equipment as well as a taller canopy, the Ar 195 was intended as a torpedo bomber to equip Nazi Germany's first aircraft carrier, the Graf Zeppelin, which was named after Graf Ferdinand von Zeppelin, of dirigible fame. Although three prototypes were flown in 1937, the design did not meet the requirements of the specification. It suffered  an excess of drag which was detrimental to its flyability, and so was rejected in 1938 in favour of the Fieseler Fi 167, which was considered superior.

ERL (automobile manufacturer). ERL, from the initials of its creator Eskil Roland Lindström, was an automobile manufacturer from Mölndal, Sweden. Lindström was a race driver during the mid-war period, and after World War II he built a series of nine sports cars made out of parts from motorcycles and standard cars. The first engine came from a Douglas motorcycle; later it was replaced by a 600 cc two-stroke DKW engine giving 14.5 HP. It was connected to a three-speed gearbox mounted in the middle of the car. The grille came from a Ford Model B, but lowered. Many of the chassis parts came from the BMW Dixi, a German copy of Austin Seven. The car was very light, only 520 kg and the top speed was 100 km/h.

Floating nuclear power plant. A floating nuclear power plant is a floating power station that derives its energy from a nuclear reactor. Instead of a stationary complex on land, they consist of a floating structure such as an offshore platform, barge or conventional ship.

Since the reactors employed are smaller in size and power than most commercial land-based reactors, mostly derived from nuclear ship and submarine power plants, the power output is generally a fraction of a conventional nuclear power plant, usually around 100MWe, although some are planned to have as much as 800MWe. 

The advantage of such power plants is their relative mobility and their ability to deliver in-situ electric power "on demand" even to remote regions, since they can be moved or towed to position with relative ease within large water bodies, and then docked with coastal facilities to transfer the produced power and heat to a land power grid. However, environmental groups are concerned that floating nuclear power plants are more exposed to accidents than onshore power stations and also pose a threat to marine habitats.

History

20th century 
The first floating nuclear power station was the MH-1A, using  pressurized water reactor built in a converted Liberty ship, which achieved criticality in 1967. Proposals to build a floating nuclear power plants off the coast of New Jersey and  off Jacksonville, Florida were considered in the 1970's but ultimately scrapped.

21st century 

In the 21st century, Russia has led in the practical development of floating nuclear power stations. On 14 September 2019, Russia’s first-floating nuclear power plant, Akademik Lomonosov, arrived to its permanent location in the Chukotka region. It started operation on 19 December 2019.

In 2022, the United States Department of Energy funded a three-year research study of offshore floating nuclear power generation. In October 2022, NuScale Power and Canadian company Prodigy announced a joint project to bring a North American small modular reactor based floating plant to market.

Samsung and UK-based Core Power are also looking into using compact molten salt reactor technology in floating platforms, with the former aiming at a modular power barge of up to 800MWe.

Advantages 
 Virtually no land or concrete is used.
 Earthquake resistant.
 Easily transported for relocation, refueling, refurbishment and decommissioning.
 Surrounded by water that can be used for active or passive cooling.
 Available to remote locations where a conventional power plant would be unfeasible.

Sarkeys Energy Center. Sarkeys Energy Center is the largest and tallest building on the campus of the University of Oklahoma (OU), Norman, Oklahoma, United States. It houses several academic units mainly centered on the Earth sciences.

Overview

The Sarkeys Energy Center is a large complex that is home to several academic units of the University of Oklahoma including the Mewbourne College of Earth and Energy (MCEE), the College of Atmospheric and Geographic Sciences (A&GS), and Chemical, Biological and Materials Engineering (COE). The Energy Center is currently owned and occupied by the University of Oklahoma.

Details of the Tower and Complex
Construction of the Energy Center was begun on November 16, 1990, and was completed by the dedication in late 1991. Funds granted by petroleum companies for use by the University of Oklahoma, loans by federal United States government, and donations by charitable individuals were all used to finance the 50 million dollar project. The Sarkeys Energy Center Complex occupies over  on the University of Oklahoma's Norman campus. The complex has  of office space, a cafe, and two large levels of laboratories and storage rooms. The ground level, level 2, is home to the Laurence S. Youngblood Energy Library. The library has approximately 170,000 map sheets, and 100,000 cataloged volumes covering a variety of geoscience topics. The tower of the Sarkeys Energy Center is 15 floors tall, and is used for most of the office space in the complex. The roof of the tower marks the highest spot on the OU campus , and is also the tallest office building in the city of Norman. The complex contains walks, fountains, and extensive landscaping.

Sarkeys Energy Center as it is known today, began as the Saxon Energy Center.  This was made possible by a pledge of a $30M donation made in 1981 by Bill D. Saxon.  O.U. wound up receiving 90,000 shares in lieu of the donation toward the energy center.  Because of the need for completion funds, Sarkeys Foundation provided the bulk of the construction funding.

Role of Center in Geophysics
The Sarkeys Energy Center is host to many conferences, talks, and meetings among leading geophysicists. The complex includes an auditorium for speeches and talks. On May 21, 2002, the University of Oklahoma was named International Academic Advocate of the Year because of its foreign policy conferences. The Energy Center remains an important center for research, education, and conference in the world of geophysical science.

The internationally recognized School of Meteorology within the College of Atmospheric and Geographic Sciences was located in Sarkeys until relocating to the National Weather Center (NWC).

Corsair (dinghy). The Corsair is a class of sixteen foot, three handed sailing dinghy. The boat was designed by Australian designer Alan Payne who is famous for designing Sir Frank Packer's America's Cup challenge yachts Gretel and  Gretel II.

The boat 
The boat is built in fiberglass, originally by De Havilland Marine (Sydney c1967), then Blue Water marine (until 2008) and most recently Corsair Dinghy Marine. It is a rather heavy boat, with minimum race weight being 136 kg and many boats frequently exceeding that. The sail area for the weight is small, leading to the boat acting similarly to a small keelboat in feel. The overhanded crew and no leaning-out devices add to this effect. This also makes the boat ideal for sail training as its strength and stability allow inexperienced sailors to jump in with more knowledgeable instructors; the boat is capable of taking up to 6 people and sometimes more in training situations. The class is also preferred by elder yachties as less physical strength or balance is required to race these boats with a "mind over matter" approach to sailing; there are still regular competitors with ages past 70.

National title 
The Corsair Class Association of Australia has since 1970 held an annual National Championship regatta over the Christmas-New Year period. This event currently encompasses three separate National Championship crowns; the most significant is the Open National Championship which determines the best Corsair Sailor in the country. Concurrently there is a National Cadet Championship for the Australian Navy Cadets who currently use the Corsair as their official training class. This championship has been run since the 1981 regatta. Since 1988 there has also been a National Youth Championship for competitors under the age of 21.

The championship is fairly laid-back for most sailors, with a schedule that includes many social and family events. This is reflected in the giving out of the "Family Trophy" for the highest placed family crew and the "Bottoms Up" award for the crew with the most capsizes.

Cray X2. The Cray X2 is a vector processing node for the Cray XT5h supercomputer, developed and sold by Cray Inc. and launched in 2007. 

The X2, developed under the code name Black Widow, was originally expected to be a standalone supercomputer system, superseding the Cray X1 parallel vector supercomputer. However, the X2 was eventually launched as one of the four processor "blade" options for the XT5h system. 

An X2 blade comprises two nodes, each with four symmetric multiprocessing vector processors and 32 or 64 GB of shared memory. Each node has a peak performance of more than 100 gigaflops. X2 processors are connected using a radix-64 "fat-tree" interconnect implemented by the YARC router ASIC. X2 blades also link into the XT5h system via its SeaStar2+ processor interconnect. 

Up to 256 X2 blades can be installed in an XT5h system. The X2 processor nodes integrate with the Cray XT5h's UNICOS/lc OS, user environment, and storage subsystem, as part of the Rainier project.
