Eagle Computer
Eagle Computer of Los Gatos, California, was an early microcomputer manufacturing company. Spun off from Audio-Visual Laboratories (AVL), it first sold a line of popular CP/M computers which were highly praised in the computer magazines of the day. After the IBM PC was launched, Eagle produced the Eagle 1600 series, which ran MS-DOS but were not true clones. When it became evident that the buying public wanted actual clones of the IBM PC, even if a non-clone had better features, Eagle responded with a line of clones, including a portable. The Eagle PCs were always rated highly in computer magazines.

Semantic Support of Cultural Heritage
The usage of semantics is not new in cultural heritage disciplines. They are commonly used to define standards for meta-, para-, and provenance information for documenting and archiving. Examples of such standards are LIDO and MIDAS Heritage. These XML schema standards are still used in cultural heritage. In recent years, however, the emergence of the Semantic Web has provided the much-required boost to semantic frameworks and technologies. It also dictates how semantics are defined and used today. Techniques and tools that formalize semantics through formalized knowledge representations have become the norm in different fields applying semantics.

IBM Building (Honolulu)
The IBM Building is an office building in Honolulu located at 1240 Ala Moana Boulevard. Designed by Vladimir Ossipoff, the building opened in 1962 as the Honolulu headquarters for IBM. It is presently owned by Howard Hughes Corporation, serving as a sales center for their surrounding Ward Village development. Construction of the IBM Building cost $1,500,000 (equivalent to $12,678,218 in 2019). The building was dedicated on October 10, 1962, in a ceremony attended by officials including then-Governor of Hawaii William F. Quinn. The roughly cube-shaped structure is distinguished by the honeycomb structure of its concrete brise soleil, inspired by Polynesian culture and also intended to resemble the punched cards used in the computer industry at the time of its construction. The building was slated for demolition by then-owner GGP Inc. as part of a 2008 redevelopment plan, but public backlash led to its preservation after the planned development area was purchased by Howard Hughes Corporation, which expressed an intent to maintain the IBM Building's name and general appearance. The development company instead renovated the building to use as an information and sales center for their surrounding Ward Village development.

Use of Bio-Inspired Design Tools by Industry Professionals
Bio-inspired design (BID) has the potential to evolve the way engineers and designers solve problems. Several tools have been developed to assist one or multiple phases of the BID process. These tools, typically studied individually and through the performance of college students, have yielded interesting results for increasing the novelty of solutions. Human-centered design (HCD) and “design thinking” have become standard practice in consumer-product design and development. Now, it is common for industrial designers, engineers, and product managers to be conversant in the process and methodologies of HCD.

List of Nuclear Reactors
This is a list of all the commercial nuclear reactors in the world, sorted by country, with operational status. The list only includes civilian nuclear power reactors used to generate electricity for a power grid. All commercial nuclear reactors use nuclear fission. As of April 2020, there are 440 operable power reactors in the world, with a combined electrical capacity of 390 GW. Additionally, there are 55 reactors under construction and 109 reactors planned, with a combined capacity of 63 GW and 118 GW, respectively. 329 more reactors are proposed. For non-power reactors, see List of nuclear research reactors. Where not otherwise specified, all information is sourced from the Power Reactor Information System (PRIS) of the International Atomic Energy Agency (IAEA).

The NIST World Trade Center Disaster Investigation
The National Construction Safety Team Act (NCST Act), signed into law on October 1, 2002 by President George W. Bush, mandated the National Institute of Standards and Technology (NIST) to establish the likely technical cause or causes of the three building failures that occurred on September 11, 2001 at the World Trade Center as a result of a terrorist attack. NIST issued its final report on the collapse of the World Trade Center Twin Towers in September 2005. It issued its final report on 7 World Trade Center in November 2008. NIST concluded that the collapse of each tower resulted from the combined effects of airplane impact damage, widespread fireproofing dislodgment, and the fires that ensued. The sequence of failures that NIST concluded initiated the collapse of both towers involved the heat-induced sagging of floor trusses pulling some of the exterior columns on one side of each tower inward until they buckled, after which instability rapidly spread and the upper sections then fell onto the floors below. World Trade Center Building 7 (7WTC), which was never directly hit by an airplane, collapsed as a result of thermal expansion of steel beams and girders that were heated by uncontrolled fires caused by the collapse of the North Tower and failure of the fire-resistive material.

InN SAs for Ultrafast Lasers
New fabrication methods are strongly demanded for the development of thin-film saturable absorbers with improved optical properties (absorption band, modulation depth, nonlinear optical response). In this sense, we investigate the performance of indium nitride (InN) epitaxial layers with low residual carrier concentration (<1018 cm^-3), which results in improved performance at telecom wavelengths (1560 nm). These materials have demonstrated a huge modulation depth of 23% and a saturation fluence of 830 uJ/cm2, and a large saturable absorption around -3 x10^4 cm/GW has been observed, attaining an enhanced, nonlinear change in transmittance. We have studied the use of such InN layers as semiconductor saturable absorber mirrors (SESAMs) for an erbium (Er)-doped fiber laser to perform mode-locking generation at 1560 nm. We demonstrate highly stable, ultrashort (134 fs) pulses with an energy of up to 5.6 nJ.a

Transponder Timing
Transponder timing (also called chip timing or RFID timing) is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event. Prior to the use of this technology, races were either timed by hand (with operators pressing a stopwatch) or using video camera systems.
