Cobalt Co50 Valkyrie. The Cobalt Co50 Valkyrie is a single-engine, four to five-seat homebuilt aircraft, arranged in a canard, pusher configuration. A light aircraft intended for private ownership, it was initially being developed by Cobalt Aircraft of San Francisco, California, United States, but the company ceased operations in July 2018 and the design is now being developed by the Centauri Aircraft Company.

Design
The composite design incorporates retractable landing gear, a pusher engine configuration, a canard, twin vertical stabilizers and automatic airbrakes. A ballistic parachute is provided as an option. Passenger entry is by a large forward fold down door. Kit production is planned to be carried out in the United States.

Initially the Co50 will be sold as a kit for amateur construction, but the manufacturer intends to eventually achieve type certification. Certification is likely to be time-consuming, not least due to the electronics Cobalt has chosen being untested for aircraft use.

Operational history
The company has declined to publish the number of aircraft on order or completed.

In August 2020 there were two Co50s registered in the United States with the Federal Aviation Administration. One was built in 2014 and owned by the then defunct previous manufacturer, Cobalt Aircraft, and flagged by the FAA as "this aircraft's registration status may not be suitable for operation". The second aircraft was built in 2018 and is registered to a private company. By February 2023, there was only one aircraft still registered with the FAA, owned by the Centuri Aircraft Corp.

Accidents
The second prototype Co50 was crashed in September 2017 following a loss of aileron effectiveness in flight on a flight test at Castle Airport. The pilot was landing the aircraft using rudder and thrust only when lift was lost at an altitude of about ten feet. The aircraft impacted the ground, the right main landing gear leg separated and the wing was damaged. The pilot was not hurt.

James Hoffman. James Hoffman is a software engineer and inventor who has worked in scientific visualization and was instrumental in producing the first visualization of Costa's minimal surface. His scientific visualizations have been published in Scientific American and Nature, among other journals. Most recently, Hoffman has been involved in the solar start-up company Sun Synchrony, which is developing his solar inventions.

Scientific visualizations
James Hoffman has created software for scientific visualization, particularly of surface geometries studied in differential geometry. While a graduate student at the University of Massachusetts Amherst, James was enlisted by mathematician David Hoffman to help prove an important result in minimal surface geometry, discovering the first new examples of complete embedded minimal surfaces in more than one hundred years.  The first example, the Costa surface, was described in 1983 by Brazilian graduate student Celso Costa as an equation, but a proof that it was embedded (lacked self-intersections) was provided by David Hoffman and William Meeks, who used computer visualizations created by James to see that the surface was embedded and dissect it to prove that it was.  This finding, followed by the discovery of scores of other surfaces and families of surfaces illustrated by Hoffman's computer graphics, overturned a century-old conjecture that the only examples of such minimal surfaces where the plane, catenoid, and helicoid.

Hoffman's work has been featured in articles in Science News, Scientific American, and Nature, and he has co-authored papers in Science and Macromolecules.  He is credited with involvement in the discovery of new three-dimensional morphologies for modeling block co-polymers, such as the Split-P surface (a hybrid of the P and G triply periodic surfaces), and derived the first level set formulation for the Lidinoid surface.

Inventions

Hoffman is the co-author of a patent for an internal combustion engine with increased thermal efficiency.  He is also the inventor of a solar panel using concentrating photovoltaics (CPV) for increased efficiency.  He is President of the California solar company, Sun Synchrony, which is developing the prototype for Hoffman's CPV design, the ArcSol panel.  Hoffman has also written several technical papers about the technology, including, 'Solar Panel Performance Survey', and 'Area Efficiency, Light Capture Efficiency, and their Maximization in Solar Tracking Arrays'.

Bedford SB. The Bedford SB was a front-engined bus chassis manufactured by Bedford in England. It was launched at the 1950 Commercial Motor Show as the replacement for the Bedford OB.

It was the first Bedford vehicle to have a "forward control" design, with the driver's seat located at the right of the engine and the front axle underneath. It used a four-speed synchromesh gearbox, with five-speed gearboxes offered later. Initially only available with a Bedford petrol engine, from 1953 a Perkins R6 was an option, with a Bedford diesel and the Leyland O.350 options from 1957, and the Leyland O.370 from 1963.

Wheelbase length was originally 17 ft 2in (5.23 m), but from 1955 an 18 ft (5.49 m) option was also offered. Bodywork was provided by a wide range of builders, including Duple, Marshall, Plaxton, Harrington and Willowbrook. It was primarily fitted with one door, although examples were fitted with two.

From 1968, the SB series used computer classification codes from Bedford's parent company General Motors, with the petrol-engined SB3 variant becoming NFM, and the diesel-engined SB5 variant becoming NJM. However, they were rarely referred to under these codes.

The SB was built for the UK market and export. By 1980, over 54,000 had been produced, 38,000 being for overseas operators. Production ceased after 36 years in December 1986.

The Army, RAF and Royal Navy, plus several other government departments took large numbers of them. The Armed Forces version was more austere than civilian versions and capable of being converted to ambulances in times of emergency.

The New Zealand Railways Road Services were the largest operator, purchasing over 1.200 primarily with New Zealand Motor Bodies bodywork with some fitted with Caterpillar C7 engines and Allison Transmissions.

There were numerous variants of the SB, each determined by the engine fitted:

Landing at Labis. The Landing at Labis was an airborne landing by Indonesian paratroopers on 2 September 1964 near Labis, Johore, Malaysia during the Indonesia–Malaysia confrontation.

Transported in three Indonesian Air Force C-130 Hercules aircraft, which had set off from Jakarta, only two aircraft managed to reach the target drop zone, the third aircraft crashed into the Straits of Malacca while trying to evade interception by a No. 64 Squadron RAF Javelin FAW.9 launched from RAF Tengah, Singapore. Tropical storms dispersed the parachute drop around Labis, about  north of Singapore with 98 paratroopers being inserted. The landing zone was close to the camp of the 1/10th Gurkha Rifles (1st Battalion, 10th GR, who were later joined in mopping-up operations by the 1st Battalion, Royal New Zealand Infantry Regiment (1 RNZIR) who were stationed near Malacca with the 28th Commonwealth Brigade.

Under the overall command of 4th Malaysian Infantry Brigade, operations to round up the 98 paratroopers took about a month. 1 RNZIR and 1/10th Gurkhas accounted for all but eight of the paratroopers, killing 32 and capturing 62 of the intruders at the cost of a New Zealand major killed. Patrols continued throughout the area around Labis throughout October.

Varmaland. Varmaland (, "warm land") is a village in Stafholtstungur, in the Borgarfjörður region of Iceland.  Varmaland is known as an eco-friendly producer of various kinds of vegetables, plants and flowers. These are grown in green houses which make use of local renewable energy in the form of hot water generated from nearby geothermal sources in the form of springs and geysers. Along with electric power generated in local plants that make use of this same geothermal power, the green house farmers manage to make up for much of the loss of daylight during the darker winter months.

For many years Varmaland was also a Women's college and center for teaching of cookery and domestic skills for young aspiring home makers. Spread across the Varmaland grounds and college lawns are a variety of geothermal spring openings and geysers set in low mounds. The three biggest geysers are Veggjalaug, Minnihver and Kvennaskólahver, all of which have had their geothermal power harnessed for use of their very hot water as well as for the central heating of the Varmaland swimming pool, community center, college and, of course the local green houses.

Akhil Gupta. Akhil Gupta (born 1959) is an Indian-American anthropologist whose research focuses on the anthropology of the state, development, as well as on postcolonialism. He is a professor of anthropology at the University of California, Los Angeles. He is a former president of the American Anthropological Association.

Education
Gupta attended St. Xavier's School in Jaipur and graduated in 1974. Gupta completed his undergraduate studies in Mechanical Engineering from Western Michigan University, followed by a Master's Degree in Mechanical Engineering from the Massachusetts Institute of Technology.

Career

Research
In 1992, while still at Stanford, Gupta along with fellow Stanford anthropologist James Ferguson wrote the often-cited essay, "Beyond 'Culture': Space, Identity, and the Politics of Difference." which argued that the analytic concept of culture had remained largely unproblematized by anthropological discourse, and that anthropologists of the day had failed to recognize and analyze the politics of cultural difference, how such differences were produced, and how such differences were used and abused by the state and by capital. The article argues for the examination of cultural anthropology as an unconscious mechanism of neo-imperialism.

Gupta is a leading figure in the anthropology of the state, and is the co-editor of a book of collected essays called The Anthropology of the State: A Reader.

Tenureship controversy
Gupta was unanimously approved for tenure in 1996 at Stanford, but was then denied tenure by Dean John Shoven. Following protests and mobilization by students, the dean's decision was overturned.

Mobile simulator. A mobile simulator is a software application for a personal computer which creates a virtual machine version of a mobile device, such as a mobile phone, iPhone, other smartphone, or calculator, on the computer. This may sometimes also be termed an emulator.

The mobile simulator allows the user to use features and run applications on the virtual mobile on their computer as though it was the actual mobile device.

A mobile simulator lets you test a website and determine how well it performs on various types of mobile devices. A good simulator tests mobile content quickly on multiple browsers and emulates several device profiles simultaneously. This allows analysis of mobile content in real-time, locate errors in code, view rendering in an environment that simulates the mobile browser, and optimize the site for performance. 	

Mobile simulators may be developed using programming languages such as Java, .NET and JavaScript.

Port of Coeymans. The Port of Coeymans is a relatively new marine terminal located about ten miles south of Albany, New York and the Port of Albany-Rensselaer in the town of Coeymans, United States. The port is located on the site of the former Powell & Minnock Brick Company, and is sometimes referred to as the P&M Brick Marine Terminal. The port's large open spaces, as well as access to the Hudson River and New York State Thruway, have led to its use in prefabrication projects, including the Willis Avenue and 145th Street Bridges in New York City.
The port owners Carver have invested more than $30 Million to update the facilities.

Although the Port of Coeymans states that it is poised to be a renewable powerhouse, it deals mostly with waste management. The port has been accused of skirting local environmental protection and noise ordinances. The Port of Coeymans also supported the building of the Tappan Zee Bridge on the Hudson River. Spans of the new bridge were built at the port and floated down the river. The old bridge spans were brought back to the Port, disassembled, reused or recycled.

The port built the foundation for Little Island in New York City. The project involves building structures that slide over piers on the waterfront in New York Harbor.<  
The Port is in the running to be named as a production site for the Off-shore wind projects in New York. This is part of the New York State Offshore Wind Master Plan. The port would need $130 million in additional investment to make it ready to support the off-shore wind projects. The other ports in the running would take approximately twice that. Mammoet has a 660-ton crane on site for offshore wind components.
