Yard Ramp
A yard ramp, sometimes called mobile yard ramp or container ramp, is a movable metal ramp for loading and unloading of shipping containers and vehicle trailers, without the need for permanent docking bays. A yard ramp is placed at the back of a vehicle to provide access for forklifts to ascend the ramp, quickly and safely into the container or truck body. Using a yard ramp for container loading or unloading allows the work to be carried out by a single forklift operator. Businesses handling only one or two loads per day normally find that a yard ramp is more cost effective than a permanent loading dock.

USS Cairo
USS Cairo /ˈkeɪroʊ/ was one of the first American ironclad warships built at the beginning of the U.S. Civil War. Cairo was the lead ship of the City-class gunboats and named for Cairo, Illinois. In June 1862, she captured the Confederate garrison of Fort Pillow on the Mississippi, enabling Union forces to occupy Memphis. As part of the Yazoo Pass Expedition, she was sunk on 12 December 1862, while clearing mines for the attack on Haines Bluff. Cairo was the first ship ever to be sunk by a mine remotely detonated by hand. The remains of Cairo can be viewed at Vicksburg National Military Park with a museum of its weapons and naval stores.

Sound Masking
Masking Sound is the addition of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Masking sound is not an active noise control (noise cancellation technique). Masking sound reduces or eliminates perception of sound. The technology is promoted as a widespread application to an entire area to improve the acoustical satisfaction, by improving the acoustical privacy of the space. This improves one's ability to focus and their productivity. Masking sound is analogous to light. - Sound Power and Luminosity - Sound Intensity and Light intensity - They both have spectral characteristics.

Radeon 9000 Series
The R300 GPU, introduced in August 2002 and developed by ATI Technologies, is its third generation of GPU used in Radeon graphics cards. This GPU features 3D acceleration based upon Direct3D 9.0 and OpenGL 2.0, a major improvement in features and performance compared to the preceding R200 design. R300 was the first fully Direct3D 9-capable consumer graphics chip. The processors also include 2D GUI acceleration, video acceleration, and multiple display outputs. The first graphics cards using the R300 to be released were the Radeon 9700. It was the first time that ATI marketed its GPU as a Visual Processing Unit (VPU). R300 and its derivatives would form the basis for ATI's consumer and professional product lines for over 3 years.

Racing Shell
In watercraft, a racing shell (also referred to as just a fine boat (UK) or just shell) is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing.

Miztec (Schooner Barge)
The Miztec was built as a 3-masted schooner in 1890. She was later converted to a schooner barge and served as a consort for lumber hookers on the Great Lakes. She escaped destruction in a severe 1919 storm that sank her longtime companion, the SS Myron, only to sink on the traditional day of bad luck, Friday the 13th, 1921, with the loss of all hands. She came to rest on Lake Superior's bottom off Whitefish Point near the Myron. The Miztec’s wreck was illegally salvaged in the 1980s. Artifacts from the Miztec became the property of the State of Michigan after they were seized in a 1992 Michigan Department of Natural Resources and Environment (DNRE) raid on the Great Lakes Shipwreck Museum. The State allows the museum to hold a triple sheave block and hook and a double sheave block and hook from the Miztec as a loan. Her wreck is now protected by the Whitefish Point Underwater Preserve as part of an underwater museum.

Operational Business Artifacts and Agility
Agility, a necessary condition for sustainable performance, should be a key competence of organizations in dynamic markets today. Organizations have to move faster than the market around them, both in terms of decision-making and capability development over time, to maintain a competitive advantage. Agility should therefore not only be seen as a tactic, but rather as a strategic goal by itself. Aligning information systems and businesses at the strategic implementation stage (i.e., operational level) is reported to enhance organizational agility. More specifically, reengineering business behaviors as business services, similar to the service-oriented architectural pattern in software design, is also reported to lead to flexibility and agility in organizations, as long as business knowledge is adequately modelled and interfaces between services are clearly defined. Consequently, business artifacts at the operational level of the business, if adequately modelled, represent an operational agility capability of a business.

Applications of Additive Manufacturing Technologies
The term “Additive Manufacturing (AM)” refers to those technologies of building layer upon layer from a 3D model in .STL format through seamless digital Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) integration; by varying the material used, the energy source and other macroparameters, different AM techniques can be specified and can be used for different applications. For the American Society for Testing and Standards (ASTM), there are seven types of AM: (1). Vat Photopolymerisation (VPP): the liquid photopolymer in a vat is selectively cured by light-activated polymerisation; (2).Material Jetting (MJT): the droplets of the build material are selectively deposited; (3). Binder Jetting (BJT): the liquid bonding agent is selectively deposited to join powder materials; (4). Material Extrusion (MEX): the material is selectively dispensed through a nozzle or orifice; (5).Powder Bed Fusion (PBF): the thermal energy selectively fuses regions of a powder bed; (6).Sheet Lamination (SL): sheets of the material are bonded to form an object; (7). Direct Energy Deposition (DED): focused thermal energy is used to fuse materials by melting as they are being deposited. Variable subclasses can also be identified for each of the previous seven main classes based on the materials with which they operate.
