NEi Software
NEi Software, founded as Noran Engineering, Inc. in 1991, is an engineering software company that develops, publishes and promotes FEA (finite element analysis) software programs including its flagship product NEi Nastran. The FEA algorithms allow engineers to analyze how a structure will behave under a variety of conditions. The types of analysis include linear and nonlinear stress, dynamic, and heat transfer analysis. MCT, PPFA (progressive ply failure analysis), dynamic design analysis method, optimization, fatigue, CFD and event simulation are just some of the specialized types of analysis supported by the company. NEi Software is used by engineers primarily in the aerospace, automobile, maritime, and offshore industries. The software is intended to save costs by reducing time to market; testing for function and safety; reducing the need for physical prototypes; and minimizing materials, weight and size of structures. After designers create an FEA model, analysts check for po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westminster, California
Westminster is a city in northern Orange County, California, known for its many Vietnamese refugees who immigrated to the city during the 1980s. They settled largely in Little Saigon, and the city is known as the "capital" of overseas Vietnamese with 36,058 Vietnamese Americans and at 40.2% (2010), the highest municipal prevalence of Vietnamese Americans. The Little Saigon is a district of the town. Westminster was founded in 1870 by Rev. Lemuel Webber as a Presbyterian temperance colony and was incorporated in 1957. Westminster is bordered by the city of Seal Beach on the west, by Garden Grove on the north and east, and by Huntington Beach and Fountain Valley on the south. Santa Ana, the county seat of Orange County, is east of Westminster. Westminster won the All-America City Award in 1996. In the court case '' Mendez v. Westminster'' (1947), a Hispanic man sued the Westminster School District for forcing his daughter, Sylvia Mendez, to attend a school for Mexican chil ...

Finite Element Method
The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems). To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the construction of a mesh of the object: the numerical domain for the solution, which has a finite number of points. The finite element method formulation of a boundary value problem finally results in a system of algebraic equations. The method approximates the unknown function over the domain. The sim ...

Firehole Composites
Firehole Composites (formerly Firehole Technologies, Inc.) was a supplier of computer-aided engineering (CAE) software and consulting services specializing in analysis of composite materials. Founded in 2000, the company's mission is to provide enabling technologies to further the widespread use of composite materials. Their products include Helius:MCT (a multiscale simulation tool for composite progressive failure analysis), Helius:CompositePro (a classical laminate theory and simple structural analysis tool), Helius:MatSim (an online micromechanics lamina simulator), and Prospector:Composites (an online composite material properties database hosted by IDES Inc.). Firehole’s principal product, Helius:MCT, is a simulation tool built to improve the accuracy of composite structure analysis and is available as an advanced capability add-on to commercial finite element analysis (FEA) packages (such as Abaqus and ANSYS). It is based on Multicontinuum Technology (MCT), an analysis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Design Analysis Method
The dynamic design analysis method (DDAM) is a US Navy-developed analytical procedure for evaluating the design of equipment subject to dynamic loading caused by underwater explosions (UNDEX). The analysis uses a form of shock spectrum analysis that estimates the dynamic response of a component to shock loading caused by the sudden movement of a naval vessel. The analytical process simulates the interaction between the shock-loaded component and its fixed structure, and it is a standard naval engineering procedure for shipboard structural dynamics. Background and rationale All mission-essential equipment on board military surface ships and submarines must be qualified for underwater shock loads caused by depth charges, naval mines, missiles, and torpedoes. An underwater explosion nearby a ship or submarine can be devastating to the combat readiness of the vessel. Damage may occur in the form of dished hull plating or even more serious holing of the hull. Moreover, some damag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farr Yacht Design
Farr Yacht Design, founded by Bruce Farr in Auckland, New Zealand, is a racing yacht design firm based in Annapolis, Maryland, United States. The firm is led by Patrick Shaughnessy. Its yachts measure from to . Farr develops custom and production yachts, including interiors, sails, and hull design. Farr uses outside research and development with tank testing and wind tunnels. Farr-designed yachts have won and placed well in a broad range of races.

Scaled Composites SpaceShipTwo
The Scaled Composites Model 339 SpaceShipTwo (SS2) is an air-launched suborbital spaceplane type designed for space tourism. It is manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic. SpaceShipTwo is carried to its launch altitude by a Scaled Composites White Knight Two, before being released to fly on into the upper atmosphere powered by its rocket engine. It then glides back to Earth and performs a conventional runway landing. The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California. On 29 April 2013, after nearly three years of unpowered testing, the first one constructed successfully performed its first powered test flight. Virgin Galactic plans to operate a fleet of five SpaceShipTwo spaceplanes in a private passenger-carrying service and has been taking bookings for some time, with a suborbital flight carrying an updated ticket price of US$250,000. The spaceplane could a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
