United States Air Force Seek Eagle Office. The United States Air Force SEEK EAGLE Office (USAF SEEK EAGLE Office, AFSEO) was started to improve the combat capability of the warfighter. The SEEK EAGLE Program, which is the standard for the aircraft-stores certification process of the United States Air Force (USAF), was created for this purpose. This program certifies all weapons (conventional and nuclear), suspension equipment, tanks, and pods carried externally or internally. The process includes safe upload and download procedures; flight limits for safe carriage, employment, jettison, safe escape, and ballistic accuracy verification. The SEEK EAGLE process includes the integrated use of digital modeling, simulation, and analysis; ground tests; and flight tests to obtain/generate the data needed to verify aircraft-store compatibility and maintain the accuracy of/support updates to the operational flight programs (OFPs) and technical orders (TOs).

United States Air Force SEEK EAGLE Office

Mission

Ensure new warfighter capabilities through the application and transfer of aircraft-store compatibility expertise.

History
The Air Force SEEK EAGLE Office (AFSEO) is a named Air Force unit and, by special order, the single point of expertise for aircraft-store compatibility. 
  
In the early stages of air warfare, aircraft-store compatibility was not a significant consideration except to ensure that weapons would fit onto and function with a carrier aircraft. During the Vietnam War, aircraft entered the inventory that were large and powerful enough to carry significant tonnage of weapons. Also, many new weapons were being developed. The management of the resulting marriage of the aircraft and weapons provided a bewildering matrix of combinations that had to be identified, prioritized, analyzed and certified in a timely manner. 
  
At the end of the war, the McDonnell Douglas F-4 Phantom was the USAF mainstay tactical combat aircraft. Virtually every store in existence was certified for use on the F-4. In the late 1970s, the USAF decided to replace the F-4 with the General Dynamics F-16 Fighting Falcon. The F-16 exhibited many more incompatibilities with weapons than the F-4 did. As the F-4 was phased out, the F-16 combat users found they were not getting the quantity and quality of combat capability they were expecting. Their mounting frustration culminated in 1986 when the Commander of the Tactical Air Command challenged HQ USAF to fix the problem. HQ USAF directed the SEEK EAGLE revitalization study. That study resulted in the establishment of the AFSEO in December 1987, when the office was chartered by the Secretary of the Air Force.

Bromocresol purple. Bromocresol purple (BCP) or 5′,5″-dibromo-o-cresolsulfophthalein, is a dye of the triphenylmethane family (triarylmethane dyes) and a pH indicator. It is colored yellow below pH 5.2, and violet above pH 6.8. In its cyclic sulfonate ester form, it has a pKa value of 6.3, and is usually prepared as a 0.04% aqueous solution.

Uses

Bromocresol purple is used in medical laboratories to measure albumin. Use of BCP in this application may provide some advantage over older methods using bromocresol green. In microbiology, it is used for staining dead cells based on their acidity, and for the isolation and assaying of lactic acid bacteria.

In photographic processing, it can be used as an additive to acid stop baths to indicate that the bath has reached neutral pH and needs to be replaced.

Bromocresol purple milk solids glucose agar is used as a medium used to distinguish dermatophytes from bacteria and other organisms in cases of ringworm fungus (T. verrucosum) infestation in cattle and other animals.

pH Indicator
Similar to bromocresol green, the structure of bromocresol purple changes with pH. Changing the level of acidity causes a shift in the equilibrium between two different structures that have different colors. In near-neutral or alkaline solution, the chemical has a sulfonate structure that gives the solution a purple color. As the pH decreases, it converts to a sultone (cyclic sulfonic ester) that colors the solution yellow.  In some microbiology tests, this change is used as an indicator of bacterial growth.

Alfred P. Southwick. Alfred Porter Southwick (May 18, 1826 – June 11, 1898) was a steam-boat engineer, dentist and inventor from Buffalo, New York. He is credited with inventing the electric chair as a method of legal execution. He was also a professor at the University of Buffalo School of Dental Medicine, now known as the State University of New York at Buffalo.

Electric chair

In 1881, Alfred Southwick conceived the idea of electrical execution when he heard the story of an intoxicated man who touched a live electric generator. Given that the man died so quickly, Southwick, a Quaker, concluded that electricity could be used as an alternative to hanging, making executions more humane. His first application for this phenomenon was to help invent a way to euthanize stray dogs at the Buffalo SPCA, but within a year he was publishing his ideas on using this method for capital punishment in scientific journals. As Southwick was a dentist who was accustomed to performing procedures on subjects in chairs, his device for electrical execution appeared in the form of an "electric chair".

After a series of botched hangings in the United States, there was mounting criticism of this form of capital punishment and the death penalty in general. In 1886 newly elected New York State governor David B. Hill set up a three-member death penalty commission to find a more humane form of execution. The committee included Southwick, human rights advocate and reformer Elbridge Thomas Gerry, and New York lawyer and politician Matthew Hale. They explored many forms of execution and in 1888 recommended electrocution using Southwick's electric-chair idea with metal conductors attached to the condemned person's head and feet. With their advice, the first law allowing the use of electrocution went into effect in New York State on January 1, 1889. Development of Southwick's idea into a working device was turned over to the New York Medico-Legal Society.

On August 6, 1890, William Kemmler was executed by electrocution. Southwick was present and is reported to have said, "There is the culmination of ten years work and study! We live in a higher civilization from this day."

Southwick died in 1898, aged 72, and was interred at the Forest Lawn Cemetery in Buffalo, New York.

In popular culture
The Netflix series F Is for Family features a school named the Alfred P. Southwick elementary school. In season 4 the students perform in a theater play about the origins of the electric chair and the life of Alfred P. Southwick.

Skin pack. Skin pack, or skin packaging, is a type of carded packaging where a product (or products) is placed on a piece of paperboard or in trays, and a thin sheet of transparent plastic is placed over the product and paperboard or trays.
The printed paperboard/tray usually has a heat-seal coating. The plastic film (LDPE, ionomer, etc.) is softened by heat and draped over the product on the card/tray.  Vacuum is used to assist a firm fit.  The film bonds to the heat-seal coating on the paperboard.  

The substrate can be either made specifically for skin packaging, or converted from other paper stock, such as corrugated board. The specially made sheets Solid Bleached Sulfate (SBS) are porous, and allow the vacuum to flow directly through the paper.  Most other stocks  need to have the sheet perforated with pinholes to allow airflow.  

The skin-packed piece may then need to be cut into individual units. Cuts such as keyslots, round corners and internal die cuts may be added during the cutting process once the skin pack is secured tightly. 

Self-adhesive film with an uncoated card is also sometimes used.

Skin packaging somewhat resembles a blister pack, with the major difference being that the plastic surrounding the product is formed over the product instead of being pre-formed.

Types of plastic film:
Polyethylene
Ionomer
PET

Meat

Fresh meat can be vacuum-packed and skin-packed.  Specialized packaging operations are needed to maintain product appearance and safety.   Temperature control during the cold chain is needed for proper shelf life.

Taifun (rocket). Taifun (German for "typhoon") was a German World War II anti-aircraft unguided rocket system. Waves of small, relatively cheap, Taifun flak rockets were to be launched en masse into Allied bomber formations. Although never deployed operationally, the Taifun was further developed in the US as the 76mm HEAA T220 "Loki" Rocket.

Design and development

Development of the Taifun project started towards the end of 1944. , an officer at Peenemünde, had been working on the Wasserfall guided missile but had become dissatisfied with the project's complexity and proposed a cheap unguided rocket as an alternative.  Designs were submitted to the Ministry of Aviation in September 1944 with Scheufelen named as the administrative officer in charge of development.

The Taifun proposal was developed by a small team at Peenemünde and its manufacturing arm (the Electromechanische Werke in Karlshagen). Their design was a  long, spin stabilized unguided rocket with four small fins at the base. The rockets were fired from either a 30 or 50 barrel launcher mounted on an adapted 88 mm gun mounting.

The rocket was driven by a liquid fueled engine. The liquid propellant used was a hypergolic mixture consisting of an Oxidizer and a Fuel.  Salbei (Red Fuming Nitric Acid) oxidizer was mixed with a Visol (Vinyl Ether) based fuel (some sources give the fuel as Tonka 250 or Dibutyl Ether). The fuel and oxidizer were fed into the combustion chamber under pressure.  The pressure was provided by small cordite charges fired into the fuel tanks, in the process bursting a pair of thin diaphragms to allow the fuel and oxidizer to flow into the combustion chamber, propelling the rocket.

A solid propellant version of the Taifun, called the Wirbelsturm (German for "Tornado"), was designed in parallel with the liquid fueled models but was not put into production. Post war, the unbuilt solid propellant version was used as the basis of design for the Soviet R-103 and R-110 unguided surface-to-air rockets.

The Taifun's nose was fitted with a contact fuze. One of the two contact fuze designs, developed by Mende Radio of Dresden, used a condenser, charged by the ionization of the exhaust gas stream, discharging through a tube in rocket's nose, the other, developed by Rheinmetall-Borsig used a conventional impact fuze design. A timed self destruct fuze was fitted to the rear of the Taifun to destroy the rocket if it failed to hit a target. The Taifun's developers believed contact fuzes were superior to time fuzes against large bombers flying in formation (a view widely held among German flak specialists).

Production began in January 1945. More than 600 of an initial batch of 10,000 were completed by VE day. No Taifun rockets were deployed operationally.

Survivors
Two Taifun rockets are displayed at the Royal Air Force Museum Cosford, UK.

Fokker F26. The Fokker F26 was an early jet airliner design created by the Dutch aircraft manufacturer, Fokker.

Development
During the era before the Second World War, Fokker was one of the world's largest manufacturers of passenger aircraft. After the re-emergence of the Fokker company in 1945 (its founder, Anthony Fokker, had died in the United States in 1939), the company made ambitious plans for reconquering the market it once dominated. Therefore, in 1946, the company came up with a design of a jetliner.

The design materialised through cooperation between Fokker, the Dutch airline company KLM, and the Dutch national institute for aircraft development, the Nationaal Instituut voor Vliegtuigontwikkeling (NVI). Design progressed quickly and a model of the F26 was shown at the first postwar aviation fair, the Paris Air Show of November 1946. The model attracted a lot of interest, but no orders were gained.

Further development of the F26 was hampered by the attitude of KLM. KLM executive Mr Plesman believed that design, marketing and production of a jetliner was too big a project for Fokker alone. He therefore pushed Fokker for cooperation with British manufacturer de Havilland. Although some cooperation took place, mainly on engine-related issues, a combined effort in producing jetliners never took place. However, within ten years, Fokker would develop a more feasible design, the turboprop-powered F27 Friendship.

The F26 Phantom was a conceptual design that was to be a technical and economical feasibility study only. Therefore, the F26 was never intended to become reality. On the other hand, the Fokker Company expressed the expectation at the Paris Air Show of 1946 that the aircraft was about to fly in three years time. Regardless of what the real business expectation was, the significance of the F26 design lies in its early appearance. Although the aircraft industry in general considered jet-powered aircraft to be the future, no jet-powered passenger aircraft were designed by then.

Design
The all-metal F26 design consisted of a low-wing layout with a 17-seat pressurized fuselage, a fully retractable gear and two Rolls-Royce Nene RB.41 series I jet engines. With a thrust of 23 kN (5,171 lbf) each, these engines were the most powerful engines available at the time. The aircraft was designed for a flight crew of three people.

The passenger cabin had a single aisle layout, with two seats abreast on the right and a single row on the left. A toilet was located in the aft of plane and there were two cargo bays. The aircraft was to be crewed by two pilots and one radio operator.

Based on design studies the F26 had an economical cruise speed of 800 km/h (497 mph) with a range of 1,000 km (621 mi).

Telephony application server. The term telephony application server refers to an entity in a telephone network that carries out functions that are not directly related to the routing of messages through the network.

Such functions can include in-network answering machines, 800 (freephone) numbers, automatic call forwarding, conference bridges and many other types of application. In integrated telephone networks, these are mostly implemented as functions in the telephone exchange, but in more open networks such as IP telephony networks based on the SIP protocol, these are often separate computers.

In contexts where it is obvious that one is talking about telephony, such as RFC 3057, one often just calls them "application servers"; this is also common in the context of SIP (for instance in RFC 4240), because proponents argue that SIP is applicable to a much wider range of applications than just telephony.

The application server provides call-termination or subscriber-independent applications. These include such capabilities as local number portability, free-call routing resolution, conference bridge services, and unified messaging. The PSTN versions of these applications are frequently known as 800 numbers in North America. The subscriber has to explicitly place a call to the application server.

Application server applications are of two general types, those that are signaling only, and those that involve media manipulation. The former are often related to routing resolution—local number portability, free-call routing, and other services where the dialed number must be translated to a routable address. An example involving media manipulation would be conference bridge applications, something with which most business people are very familiar. The call steps include

Each user calls in on a pre-published number. 
The dialed number is translated into an IP address and named the endpoint of the application server, and the call is routed there. 
The application server connects to the media server, instructing it to play a greeting and collect the conference number. 
The media server returns and conference number, and the application server instructs the media server to play a prompt to collect the authorization number. 
If the digits collected are correct, the application server tells the media server to move this call to a particular conference bridge.
