Tiger Team
A tiger team is a team of specialists assembled to work on a specific goal, or to solve a particular problem. Origin of the term A 1964 paper entitled ''Program Management in Design and Development'' used the term ''tiger teams'' and defined it as "a team of undomesticated and uninhibited technical specialists, selected for their experience, energy, and imagination, and assigned to track down relentlessly every possible source of failure in a spacecraft subsystem or simulation".J. R. Dempsey, W. A. Davis, A. S. Crossfield, and Walter C. Williams, "Program Management in Design and Development," in Third Annual Aerospace Reliability and Maintainability Conference, Society of Automotive Engineers, 1964p. 7–8 https://doi.org/10.4271/640548. Walter C. Williams gave this definition in response to the question "How best can advancements in reliability/maintainability state-of-the-art be attained and used with compressed schedules?" Williams was an engineer at the Manned Spacecraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Scott Crossfield
Albert Scott Crossfield (October 2, 1921 – April 19, 2006) was an American naval officer and test pilot. In 1953, he became the first pilot to fly at twice the speed of sound. Crossfield was the first of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the United States Air Force and NASA. Early years Born October 2, 1921, in Berkeley, California, Scott Crossfield grew up in southern California and rural southwest Washington, a son of Albert Scott Crossfield, Sr. (May 13, 1887 – October 21, 1954) and his first wife Maria Lucia Dwyer (March 8, 1892 – March 23, 1960). Crossfield graduated from Boistfort High School southwest of Chehalis, attended the University of Washington in Seattle, then worked for Boeing. He served with the U.S. Navy as a flight instructor and fighter pilot during World War II. During this time, he flew the F6F Hellcat and F4U Corsair fighters, as well as SNJ trainers, and a variety of other aircraft. He ...

NASA Engineering And Safety Center
The Langley Research Center (LaRC or NASA Langley), located in Hampton, Virginia, near the Chesapeake Bay front of Langley Air Force Base, is the oldest of NASA's field centers. LaRC has focused primarily on aeronautical research but has also tested space hardware such as the Apollo Lunar Module. In addition, many of the earliest high-profile space missions were planned and designed on-site. Langley was also considered a potential site for NASA's Manned Spacecraft Center prior to the eventual selection of Houston, Texas. Established in 1917 by the National Advisory Committee for Aeronautics (NACA), the research center devotes two-thirds of its programs to aeronautics and the rest to space. LaRC researchers use more than 40 wind tunnels to study and improve aircraft and spacecraft safety, performance, and efficiency. Between 1958 and 1963, when NASA (the successor agency to NACA) started Project Mercury, LaRC served as the main office of the Space Task Group. In September 2019, ...

Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

Emergency Management
Emergency management (also Disaster management) is a science and a system charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies; emergencies can be understood as minor events with limited impacts and are managed through the day-to-day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also ...

Software Testing
Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the Quality (business), quality of software and the risk of its failure to a User (computing), user or sponsor. Software testing can determine the Correctness (computer science), correctness of software for specific Scenario (computing), scenarios but cannot determine correctness for all scenarios. It cannot find all software bug, bugs. Based on the criteria for measuring correctness from an test oracle, oracle, software testing employs principles and mechanisms that might recognize a problem. Examples of oracles include specifications, Design by Contract, contracts, comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, and applicable laws. Software testing is often dynamic in nature; running the software to verify actual output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Red Team
A red team is a group that simulates an adversary, attempts a physical or digital intrusion against an organization at the direction of that organization, then reports back so that the organization can improve their defenses. Red teams work for the organization or are hired by the organization. Their work is legal, but it can surprise some employees who may not know that red teaming is occurring, or who may be deceived by the red team. Some definitions of red team are broader, and they include any group within an organization that is directed to think outside the box and look at alternative scenarios that are considered less plausible. This directive can be an important defense against false assumptions and groupthink. The term ''red teaming'' originated in the 1960s in the United States. Technical red teaming focuses on compromising networks and computers digitally. There may also be a Blue team (computer security), blue team, a term for cybersecurity employees who are respons ...

Penetration Test
A penetration test, colloquially known as a pentest, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; this is not to be confused with a vulnerability assessment. The test is performed to identify weaknesses (or vulnerabilities), including the potential for unauthorized parties to gain access to the system's features and data, as well as strengths, enabling a full risk assessment to be completed. The process typically identifies the target systems and a particular goal, then reviews available information and undertakes various means to attain that goal. A penetration test target may be a white box (about which background and system information are provided in advance to the tester) or a black box (about which only basic information other than the company name is provided). A gray box penetration test is a combination of the two (where limited knowledge of the target is shared with the auditor). A penetration test ...
