Cascade Kasperwing I-80. The Cascade Kasperwing I-80 is an American ultralight flying wing motorglider that was designed by Witold Kasper and Steve Grossruck. It was produced by Cascade Ultralites and introduced in 1976. The aircraft was supplied as a kit for amateur construction.

Design and development
The I-80 was designed long before the US FAR 103 Ultralight Vehicles rules were introduced, but the aircraft fits into the category, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a cable--braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from bolted together aluminum tubing, with the wing Dacron sailcloth covered. Its  span, single-surface wing employs a special Kasper-designed airfoil that allows both normal flight and a fully controlled, completely stalled parachutal descent mode. The wing is cable-braced from a single kingpost. The pilot is accommodated in a nylon-web swing seat. The controls are unconventional, with pitch controlled by weight shift and roll and yaw controlled by canted-outwards wing tip rudders. The powerplant is a Zenoah G-25 of . The landing gear is of tricycle configuration, with a steerable nosewheel that has reversed controls; the pilot pushes the right pedal to go left and vice versa.

The aircraft achieves a glide ratio of 10:1 at .

The I-80 can be fully disassembled for transport, including reducing the wing to a compact bag of tubing, while the fuselage cage remains assembled

Mark H. A. Davis. Mark Herbert Ainsworth Davis (25 April 1945 – 18 March 2020) was Professor of Mathematics at Imperial College London. He made fundamental contributions to the theory of stochastic processes, stochastic control and mathematical finance.

Education and career
After completing his BA degree in Electrical Engineering at the University of Cambridge, Davis pursued his PhD degree at UC Berkeley under the supervision of Pravin Varaiya. His PhD thesis, obtained in 1971, initiated the martingale theory of stochastic control. Returning to the UK in 1972, Davis joined the Control Group at Imperial College London. From 1995 to 1999 he was Head of Research and Product Development at Tokyo-Mitsubishi International, leading a quantitative research team providing pricing models and risk analysis for fixed income, equity and credit-related products. He returned to Imperial College London in August 2000 to build Imperial’s Mathematical Finance group within the Department of Mathematics.

Research
Davis   made several contributions to the theory of stochastic processes, stochastic control and mathematical finance.
His doctoral thesis initiated the martingale approach for the study of conditions for the optimal control of stochastic systems given by Ito equations. The approach permitted arbitrary non-anticipative feedback controls and remains the standard way of formulating stochastic control to this day.
One of his key contributions is the martingale optimality principle in stochastic control, which characterizes optimal strategies through the martingale property of the value process. In a 1984 paper he introduced the concept of Piecewise deterministic Markov process, a class of Markov models which have been used in many applications in engineering and science.

In the early 1990s, Davis introduced the deterministic approach to stochastic control by means of appropriate Lagrange multipliers. He was awarded the Naylor Prize by the London Mathematical Society in 2002 for his "contributions to stochastic analysis, stochastic control theory and mathematical finance" and delivered a lecture titled Optimal investment with randomly terminating income.

Davis was one of the founding editors of the journal Mathematical Finance. He  authored   three books on stochastic analysis and optimization.

John Corbett (chemist). John Dudley Corbett (March 23, 1926 – September 2, 2013) was an American chemist who specialized in inorganic solid-state chemistry.  At Iowa State and Ames Lab, Corbett lead a research group that focused on the synthesis and characterization of two broad classes of materials, notably Zintl phases and condensed transition metal halide clusters. Both classes of materials are important for their uses, for instance thermoelectrics, and for the theoretical advances they made possible by working to understand their complex bonding and electronic properties.

Career 
After graduating from Yakima High School, serving in the United States Navy until the end of World War II, and attending the North Dakota Teachers College, the University of Wisconsin–Madison, and the University of Washington, Corbett remained at Washington to complete his Ph.D. in 1952. He joined the chemistry faculty of Iowa State University and the scientific staff of Ames Laboratory in 1953.  He was affiliated with both institutions for his entire career, and served as chair of the Department of Chemistry between 1968 and 1973. He was elected a Fellow of the American Association for the Advancement of Science. He was awarded two DOE Awards for Outstanding Scientific Accomplishments and Sustained Research in Materials Chemistry, the Humboldt Prize (1985), the 2005 Spedding Award from the Rare Earth Research Conference, the 2008 Monie A. Ferst Award from Sigma Xi, and several ACS Awards for both Inorganic Chemistry and Distinguished Service in the Advancement of Inorganic Chemistry. He was elected to the United States National Academy of Sciences in 1992.

Personal life
Corbett was born to parents Alexander and Elizabeth Corbett in Yakima, Washington, on March 23, 1926, and had two brothers. He was married to F. Irene Lienkaemper from 1948 until her death in 1996. The couple raised three children. Corbett died on September 2, 2013, at the age of 87, following a stroke. The John D. Corbett Professorship was established in 2007, within Iowa State University's Department of Chemistry.

Clean agent FS 49 C2. Clean agent FS 49 C2 is an environmentally engineered, human safe, fast acting Clean Agent fire extinguishing gas for gaseous fire suppression installed in a suited fire suppression system.  The gas consists of tetrafluoroethane, pentafluoroethane and carbon dioxide.

FS 49 C2  maintains breathable concentrations of oxygen in the air. It can extinguish a fire with less danger to people in the room at extinguishing concentrations in contrast to pure carbon dioxide based fire suppression system that is deadly to humans when released in extinguishing amounts. 

The gas was initially called Halotron II B/FS49C2.

Thermal fire suppression 
FS 49 C2 acts similarly to an inert gas. It absorbs the heat produced from the combustion process. This mechanism is consistent with the observation that the fire heat release rate does not decrease until sufficient gas is released.

The difference from inert gases and FS 49 C2 is that it takes less gas to suppress a fire, and therefore gas storage takes less space, depending on the storage pressure. Savings may vary between a 50-90%.

Composition 
It is a gaseous mixture of 60-80% tetrafluoroethane (R-134a), 10-30% pentafluoroethane (R-125) and 10-30% carbon dioxide (CO2). 

Its physical properties are similar to those of Halon 1301.

Halon comparison 
FS 49 C2 is believed to cause less damage to the environment. Its main component is the most widely used replacement gas for refrigeration systems, characterized by zero Ozone Depletion Potential (ODP) factor. FS 49 C2 is suitable to replace Halon 1301 as a "drop in" upgrade of existing Halon systems.

Filling a room 12% by FS 49 C2 is sufficient to suppress a flame-based fire.

Even though FS 49 C2 gas does not leave toxic gases behind, a self-contained breathing apparatus is recommended when in a fire site because in the process of extinguishing the fire, FS 49 C2 may release potentially harmful gases.

Montreal protocol 
UNEP banned the use of Halon gases in the Montreal Protocol treaty in 1987 due to ozone depletion and the ozone-depleting effect of Halon gases. Developing countries were granted an extension to still use Halon until 2010. After 2010 UNEP recommended that those countries replace Halon with ozone friendly alternatives.

Mason Greater Meteor. The Mason Greater Meteor also called the Warren & Montijo Monoplane, the Glenmont Landau Sedan, the Belmont Cabin Monoplane M-1, the Mason Meteor M, the Mason Greater Meteor M-200 and the Pride of Hollywood was the first aircraft built by California Polytechnic College students.

Design and development
First built by Cal Poly students, the aircraft was registered under many names. On 17 March, the aircraft was christened with grape juice as the "Glenmont". In April 1928 aircraft was first registered as the Warren & Montijo Monoplane. The aircraft was painted silver with a winged logo on either side that featured a W(Warren) and a M (Montijo) with Landau Sedan written below it. In August 1928 the aircraft was sold as a Glenmont Landau Sedan and renamed shortly afterward as the Belmont Cabin Monoplane M-1
By 1933 the aircraft was registered as the Mason Meteor M''' and Mason Greater Meteor M-200''.

The aircraft was constructed with a welded steel tube fuselage with aircraft fabric covering. The wings used spruce spars with Haskelite covering. It featured conventional landing gear and was powered by a  9-cylinder Salmson 9 radial engine. The first modification to the aircraft was lowering the engine for improved forward visibility. In 1933 the fuselage was rebuilt and a new Pratt & Whitney Wasp engine was installed. The Mason Aircraft Company installed six fuel tanks in the cabin with an interconnecting tube and a receptacle for aerial refueling mounted above the wing.

Operational history
The aircraft was first flown by Warren, and Montijo, on 3 March 1928 at a field that would eventually become the San Luis Obispo County Regional Airport. Originally built as a school project, the aircraft served as a passenger plane, then was modified as a non-stop aerial refueling record-setting aircraft, then again as an aerial broadcasting booth for NBC with the call sign KHRCX. On 29 April 1934, the aircraft crashed in a landing accident at Long Beach, California

ID-WSF. In computer networking, Identity Web Services Framework is a protocol stack that profiles WS-Security, WS-Addressing, SAML and
adds new protocol specifications of its own, such as the Discovery Service, for open market per user service
discovery, and the People Service for delegation and social networking.

Development
The ID-WSF stack was developed by the Liberty Alliance. The first release, ID-WSF 1.0 (and subsequent 1.1 and 1.2) were
released in 2003. ID-WSF1 was interoperability tested among
several vendor implementations, which received certification from the Liberty Alliance.

However, the first version of ID-WSF was not widely adopted. Perhaps the only significant adoption was by France Telecom
and the French government's Mon Service Public. Some adoption happened in Japan as well. Liberty Alliance proceeded
to create an improved version, the ID-WSF 2.0 in 2006, which included harmonization with certain WS-* technologies,
such as WS-Addressing and WS-Security. These changes were vigorously, and successfully, lobbied by Conor Cahill
of AOL (at the time). ID-WSF 2.0 interoperability certification was participated by several major league vendors, as well
as by startups and open source projects.

Since then, ID-WSF 2.0 has become the only widely accepted interoperable profile of WS-* technologies. Its strength
is essentially in narrow focus where tight enough profile for interoperability was specified. ID-WSF 2.0 interoperability
certification by Liberty Alliance was accomplished by several vendors, including some open source.

ID-WSF 2.0 has been adopted as standards base by the Finnish e-government project and by the European Commission FP7 project TAS3.

Manta Foxbat. The Manta Foxbat is an American ultralight aircraft that was designed by Bill Armour and produced by Manta Products Inc of Oakland, California. The aircraft was supplied as a kit for amateur construction.

Design and development
The Foxbat was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a cable-braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with the wing covered in Dacron sailcloth. Its  span wing is supported by cables strung from an inverted V style kingpost. The wing is derived from the Manta Fledge hang glider wing. The control system is unconventional and uses a hang glider style control bar for weight shift control of pitch and roll, augmented with wing tip rudders for yaw, activated by hand controls on the control bar. The fuselage is an open frame structure that is attached to the wing via a flexible single point mount, to allow weight shift control. The pilot is accommodated on a sling seat. The landing gear is of tricycle configuration, with a steerable nose wheel.

The Foxbat wing can be folded for ground transport and storage.
