253rd Cyberspace Engineering Installation Group. The 253rd Cyberspace Engineering Installation Group (253 CEIG) is located at Otis Air National Guard Base, Massachusetts, USA.

Mission 
The primary mission of the 253rd Cyberspace Engineering Installation Group is to train, advise, and direct combat-ready units. A secondary mission is to provide a ready militia to protect life and property and provide peacekeeping services in the U.S. if called upon.

The group is available to deploy anywhere in the world on short notice and provide communications, engineering and installation services in support of the Air Force. Upon mobilization, Air Force Space Command would assume operational command of the 253 CEIG.

At the state level, the group provides forces to the Commonwealth of Massachusetts for use during local or statewide disasters.

History 
The 253rd Cyberspace Engineering Installation Group relocated from Wellesley, MA to Otis in 1996 due to mission and equipment changes.

Post Cold War 
Desert Shield/Storm began on 7 August 1991 after the invasion of Kuwait. Within ten days the 253rd Combat Communications Group units were involved in deploying equipment to support the Air Force and coalition forces in the Gulf. Volunteers from the 267CBCS, solicited by the 253rd Combat Communications Group Readiness Center, joined other Group members to deploy and support Desert Shield.

Global War on Terror 
In 2001, the 267 CBCS, collocated with the 253rd Combat Communications Group, facilitated the first use of the Theater Deployable Communications Equipment during Operation Enduring Freedom. More than 20 personnel mobilized for the mission from September 2001 to July 2003.  They augmented the Headquarters Air Combat Command staff in filling requirements for the U.S. Air Force/ANG.

Aurigan. Aurigan is a copper alloy made of 85% copper, 4% silicon, and 11% zinc. It is patented, and is used on high quality bits for horses to encourage increased salivation, which leads to a softer and more responsive mouth on the horse. Aurigan is similar in appearance to other copper alloys, but has different oxidation properties due to its composition. One advantage it has over other copper alloys such as German silver is that it is nickel-free; some horses have
been known to have a nickel allergy which appears as pimples in the mouth.

Water supply and sanitation in Pernambuco. Water supply and sanitation in Pernambuco is characterized by high levels of access to water supply in urban areas, but also by poor service quality (intermittent supply), inadequate access to sanitation, and insufficient access to improved water sources and improved sanitation in rural areas.

In urban areas, where 76% of Pernambuco's 8.4 million inhabitants live, access to house connections for water supply is 91% and access to sewerage is 49%. Concerning service quality, rationing is a constant reality in about 85% of the municipalities, including the Recife Metropolitan Region. This is primarily to a lack of water resources, particularly during the dry season, and frequent drought conditions.

The State Secretariat of Water Resources (SRH) is in charge of both water resources management and water supply and sanitation policies. The State Water Company (COMPESA) is responsible for water and sanitation service provision in most of the state. COMPESA provides urban water supply and sewerage in 170 and 20 municipalities respectively, out of 189 in the State. The remaining municipalities are served by municipal public providers. COMPESA operates under concession contracts with municipalities and is regulated and supervised by the state-level multi-sector regulatory agency ARPE.

The city of Recife has pioneered condominial sewers in Brazil.

Mike A. Horton. Mike A. Horton is an American engineer and founder of a company producing sensor technology and sensor-based systems.

Biography
Mike Horton was born October 23, 1973, in Austin, Texas, the second of two children of Claude Wendell Horton Jr. and Elisabeth Alice Becker.

Horton received a B.S. and an M.S. in electrical engineering from the University of California at Berkeley.

Company

Following Horton's graduation, he co-founded Crossbow Technology in 1995 with his advisor A. Richard Newton.  In 2003, MIT Technology Review magazine named him as one of the top young innovators under 35.

After exploring potential uses of silicon microelectromechanical systems sensor technology and experimenting with early acceleration sensors from the Berkeley Sensor and Actuator Sensor as well as commercial prototypes from Analog Devices, Horton and Newton formed a company to design and build products based on MEMS sensor technology. Crossbow Technology was founded in August, 1995. The company's initial vision was to leverage microelectromechanical systems-based sensor technology for motion-based input devices which are now used in video game systems such as the Nintendo Wii.

The company refined the technology for application in commercial aerospace, and it became the first company to be approved by the FAA as a TSO (Technical Standard Order) holder FAA for a silicon microelectromechanical systems based attitude and heading reference systems. An AHRS provides a solid-state replacement of unreliable mechanical gyroscopes as primary flight instruments, which can increase safety on general aviation aircraft.  The company's MEMS-based inertial systems are also used in automated guidance of farm tractors and unmanned aerial vehicle systems.

Starting in 2001, Horton worked with UC Berkeley professor's Kristofer S. J. Pister and David Culler to develop and produce commercially available hardware for the Smartdust and TinyOS research community. These hardware platforms became known as "motes".  The company produced several generations of "Motes" including the Mica2, Micaz, IRIS, iMote2, and TelosB.  Applications range from crop monitoring to homeland security.

Horton was the company’s CEO from its inception until it was sold to Moog Inc. in 2011.  The company’s systems were predominantly used in personal aircraft, construction and farming equipment, military weaponry, and video game consoles.  He later became the CEO of Yabberz, along with his wife Melissa Horton.

The Very Pulse of the Machine. "The Very Pulse of the Machine" is a science fiction short story  by American writer Michael Swanwick, published in 1998. It was the winner of the 1999 Hugo Award for Best Short Story.  It was also nominated for the 1999 Locus Award for Best Short Story and Asimov's Science Fiction magazine's Reader Poll. In 2022, the story was adapted into an episode of the Netflix anthology series Love, Death & Robots.

Plot summary

The story follows Martha Kivelsen, an astronaut who is in a moon rover crash while exploring the surface of Jupiter’s moon Io. The rover is destroyed, so Kivelsen decides to make a sledge from the rover's parts and drag her partner Burton’s body back to the lander before her air supply runs out. She has no time to sleep so she takes drugs to keep her awake and give her energy, but they cause her to hallucinate.  Along the way she hears a voice in her radio claiming to be Io, which is actually a machine, using Burton's body to communicate. When Kivelsen is trapped on the wrong side of a lake, Io claims it can help her cross it, and sulfur crystals make a narrow bridge over the lake. However, where Kivelsen is nearly at the lander, it is destroyed by a quake, stranding her without air. Io states it may be able to give her and Burton a form of immortality, and Kivelsen directs Io to use its flux tube to tell the rest of the Solar System about her discovery. Then she accepts the offer and jumps into a pool of molten sulfur. Whether or not she is hallucinating remains ambiguous.

Quotations
Burton is a poetry enthusiast, and Io (or Kivelsen's hallucinations) quotes several poets, including Dylan Thomas, Sylvia Plath,  Alfred, Lord Tennyson, and Edmund Hamilton Sears. It quotes several Romantic poems: Samuel Taylor Coleridge's The Rime of the Ancient Mariner, and two by William Wordsworth: The Prelude and the love poem "She Was a Phantom of Delight", from which the story takes its title.

The narration also describes Io's scenery by referring to The Wizard of Oz. While Kivelsen thinks about why she is retrieving Burton's body, she mentions the Baltimore Catechism.

Kobeseiko Te-Gō. The  was a Japanese two-seat STOL experimental reconnaissance aircraft developed by Kobe Steel in 1942 for service in World War II. In accordance with the Army's request, Professor T. Miki, Osaka Imperial University designed and Kobe Seikojo built the Te-Gō. No "Ki" code number was assigned there to since the project was outside the jurisdiction of the Army Aviation Headquarters.

This aircraft was one of two competitors for an Imperial Japanese Army STOL  liaison and observation aircraft. Inspired by the Fieseler Storch, Prof. Tetsuo Miki of Osaka University designed this aircraft.  Although the aircraft was similar to the Storch, it was not a copy.

Using construction methods common at that time, the wing were made of a wood spar and ribs, covered with fabric/plywood. Automatic slots along the length of the leading edges, large Fowler-type flaps were installed along the trailing edges, and the ailerons were also used as flaps for very short take off. The fuselage had a steel tube frame that was fabric-covered from the cockpit back and the nose was covered with sheet metal. The tail components had the same structure as the wings. A 7.7 mm flexible machine gun was planned for installation at the rear seat to obtain a clear upper rear field of fire.

The aircraft crashed, with extensive damage to the wing and landing gear. Because of this accident, the second submission, the Kayaba Ka-go autogyro, was selected  and entered service as the Kayaba Ka-1.

EAA Biplane. 

The EAA Biplane is a recreational aircraft that was designed by the Experimental Aircraft Association in the United States and marketed as plans for home-built aircraft.

Design and development
A preliminary design was produced for the EAA by a team of Allison engineers led by EAA member Jim D. Stewart in 1955. This team took the Gere Sport of the 1930s as their starting point and eventually developed a completely new design, which also incorporated several later design changes made by Robert D. Blacker, the prototype's builder and one of its test pilots. 

Blacker's design changes included adding a +2 degree of dihedral to the upper wing, redesign of the horizontal stabilizer, installation of a diagonal brace at Stations 2 and 3, a change to the fuselage truss assembly, strengthening of the control column support, and a ball-bearing arrangement. 

The design is a single-seat biplane of conventional configuration, with staggered, single-bay equal-span wings braced with N-struts. The undercarriage is of fixed tailwheel type. The fuselage is fabric-covered welded steel tube, and the wings fabric-covered wood.

This prototype EAA Biplane was built by Blacker (President of EAA Chapter 15 at the time) and his students at St. Rita of Cascia High School in Chicago, Illinois, as the second airplane completed as part of EAA's Project Schoolflight. The EAA Biplane construction began in September 1957, with a first flight in June, 1960. During the construction of the prototype, Blacker wrote several "EAA Biplane Progress Reports" published in EAA's Sport Aviation magazine. Blacker put the prototype's incomplete fuselage as on display at EAA's 1958 fly-in. The prototype EAA Biplane work, along with the other facets of Project Schoolflight, resulted in the award of the Mechanix Illustrated trophy for "Outstanding Achievement in Home-Built Aircraft". The completed prototype EAA Biplane was first publicly shown at the 1961 Rockford, Illinois Fly-In.

Operational history
Plans for the biplane remained available until 1972, with 7,000 sets sold.

Nesmith Cougar. The Nesmith Cougar is a light aircraft that was developed in the United States in the 1950s and marketed for homebuilding.

Development
The design, by Robert Nesmith, is a conventional high-wing, strut-braced monoplane with fixed tailwheel undercarriage. The pilot and a single passenger were seated side by side. The fuselage and empennage were of welded steel-tube construction, while the wings were of wood, and the whole aircraft was fabric-covered. Some later aircraft were fitted with a tricycle undercarriage.

The original Cougar design was marketed by Nesmith himself. His intent was to market a low-cost aircraft for homebuilders. He also used the aircraft as a troubled youth project to encourage teens to work together toward a goal. When a modified Cougar won an Experimental Aircraft Association (EAA) design competition in 1963, that organization took over selling plans. Rights to the design were eventually purchased by Acro Sport.

The aircraft shape was influenced by the Beechcraft Staggerwing and Wittman Tailwind. The name came from the college of Nesmith's daughter, the University of Houston, whose athletic mascot is a cougar.

Variants

Pober Pixie. The Pober Pixie is a single-seat light aircraft that was designed in the United States in 1974 and marketed as plans for homebuilding.

It is a conventional parasol-wing monoplane with fixed tailwheel undercarriage and a single open cockpit. The design was inspired by the Heath Parasol.

Development
In response to the 1973 oil crisis, the EAA launched "Project Econoplane" to develop an aircraft with high fuel economy that would therefore be affordable for its members to operate.  The Pober Pixie was the result, with a Volkswagen air-cooled engine of 1835 cc and a fuel consumption of 3 to 3.5 US Gal (11 to 13 L) per hour. Plans were completed in January 1974 and the prototype flew in late July, in time for the EAA Annual Convention that year.

After the convention, the prototype was returned to the workshop for modifications, including installation of a  Limbach SL 1700 EA engine and Rehm 5330 two-blade fixed-pitch propeller, details of which were incorporated into the plans.

Design
The Pixie fuselage is fabricated from welded 4130 steel tube, while the wings are made from Sitka spruce covered with Stits Poly-fiber fabric. Recommended engines include Volkswagen or the Continental A65.

The design includes full-span ailerons that give it a high roll rate with minimal adverse yaw.

Aircraft Spruce and Specialty says of the design:

Operational history
By March 2017, 27 examples had been registered in the United States with the Federal Aviation Administration and six with Transport Canada.

Variants
Pober Pixie II
Paul Poberezny developed some drawings and started design and partial welding of a fuselage for a two-seat model. Michael Hoye of Heath Texas purchased the project in 1989, continued the design, and over a period of ten years completed building a single scratch built example of a tandem two-seat Pixie in 2000. This aircraft won an "outstanding workmanship" award at Airventure 2001 and was featured as the cover story by noted author Budd Davisson in the January 2002 issue of Sport Aviation magazine.

Center for Coastal and Ocean Mapping. The Center for Coastal and Ocean Mapping (CCOM) / NOAA-UNH Joint Hydrographic Center (JHC) was founded in 2000 by Dr. Larry Mayer to find ways to process the massive amounts of data coming from sonar systems at rates commensurate with data collection; that is, to make the data ready for chart production as rapidly as the data could be collected.

The main objective of the CCOM/JHC is to enhance methods for ocean mapping and hydrology, with the target to also advance the knowledge of the discipline's future generation. This objective underlies the aim of the JHC and its cooperative partnerships with the University of New Hampshire and the National Oceanic and Atmospheric Administration to create a national center for expertise in ocean mapping and hydrographic sciences.

The center is located in the Chase Ocean Engineering building on the campus of the University of New Hampshire in Durham, New Hampshire, United States.

The center works on a wide range of marine research topics, including:
 Hydrography
 Improved bathymetric processing
 Improved side-scan sonar and backscatter processing
 Data visualization, with emphasis on whale tracking, flow visualization, and mid-water fish
 Seafloor characterization
 Lidar
 Photographic mosaic
 Law of the Sea mapping for the United States
 Electronic chart of the future and the marine Automatic Identification System
