Maltese Falcon (yacht)
''Maltese Falcon'' is a full-rigged ship using DynaRig technology, which was built by Perini Navi in Tuzla, Istanbul, and commissioned by her first owner, Tom Perkins. She is one of the world's most complex and largest sailing yachts at , similar in size to the ''Athena'' and ''Eos''. The vessel dropped her BVI flag in 2008 and was purchased by Pleon Ltd, which put her to charter use. Vessel The bare hull was built and launched on speculation in 1989-1990 by Perini Navi at its newly acquired shipyard in Tuzla, Istanbul, but found no takers in the aftermath of the Gulf War. Tom Perkins, a keen yachtsman and the owner of the two ''Andromeda La Dea'' Perini ketches, took an interest in the hull. In 2001 he hired Dutch yacht designers at Dykstra Naval Architects to investigate 19th-century clippers and propose a three-mast square rig for the project. The "DynaRig" concept, a 1960s invention by German hydraulics engineer Wilhelm Prölss intended to operate cargo ships with a ...

The Maltese Falcon (novel)
''The Maltese Falcon'' is a 1930 detective novel by American writer Dashiell Hammett, originally serialized in the magazine '' Black Mask'' beginning with the September 1929 issue. The story is told entirely in external third-person narrative; there is no description whatsoever of any character's thoughts or feelings, only what they say and do, and how they look. The novel has been adapted several times for the cinema. The main character, Sam Spade (who also appeared later in some lesser-known short stories), was a departure from Hammett's nameless detective, The Continental Op. Spade combined several features of previous detectives, notably his cold detachment, keen eye for detail, unflinching and sometimes ruthless determination to achieve his own form of justice, and a complete lack of sentimentality. In 1990 the novel ranked 10th in Top 100 Crime Novels of All Time list by the Crime Writers' Association. Five years later, in a similar list by Mystery Writers of America, the ...

Luxury Yachts
A superyacht or megayacht is a large and luxurious pleasure vessel. There are no official or agreed upon definitions for such yachts, but these terms are regularly used to describe professionally crewed motor or sailing yachts, ranging from to more than in length, and sometimes include yachts as small as . Superyachts are often available for charter with a staff that caters to guests at a high standard of comfort. They may be designed to emphasize comfort, speed, or expedition capability. Depending on the season, superyachts may be most frequently found in the Mediterranean or the Caribbean. Many are available for charter at prices that exceed 100,000 per week. Larger examples may have more than one swimming pool; they may carry a variety of water toys, other boats, and some a helicopter. History At the beginning of the 20th century, when wealthy individuals constructed large private yachts for personal pleasure, some manufacturers, such as Cox & King and Charles L. Seab ...

Black Pearl (yacht)
''Black Pearl'' is a sailing yacht launched in 2016, which is in length. It has three DynaRig masts supporting a sail area of . The yacht was known during its build process originally as ''Oceanco Y712'' and thereafter as "Project Solar". The hull is steel, the superstructure aluminum, and the masts carbon fiber. The yacht is owned by the family of Russian billionaire Oleg Burlakov, who died on 21 June 2021. It is expected that ''Black Pearl'' can cross the Atlantic using only of fuel, aided by regenerative technologies. One key technology to support this is to use the speed of the vessel through the water under sail to generate electricity with a variable pitch propeller. The yacht also features heat capture technologies and large scale storage batteries to capture energy generated but not immediately used. Build history Inspired by the , the intention behind the project was to push the boundaries of the DynaRig system and demonstrate the potential for larger DynaRig-equi ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Sloop
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is sometimes fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David A
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Fiber Bragg Grating
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. Hence a fiber Bragg grating can be used as an inline optical fiber to block certain wavelengths, can be used for sensing applications, or it can be used as wavelength-specific reflector. History The first in-fiber Bragg grating was demonstrated by Ken Hill in 1978. Initially, the gratings were fabricated using a visible laser propagating along the fiber core. In 1989, Gerald Meltz and colleagues demonstrated the much more flexible transverse holographic inscription technique where the laser illumination came from the side of the fiber. This technique uses the interference pattern of ultraviolet laser light to create the periodic structure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber Optic
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers. Op ...

Yard (sailing)
A yard is a spar on a mast from which sails are set. It may be constructed of timber or steel or from more modern materials such as aluminium or carbon fibre. Although some types of fore and aft rigs have yards, the term is usually used to describe the horizontal spars used on square rigged sails. In addition, for some decades after square sails were generally dispensed with, some yards were retained for deploying wireless (radio) aerials and signal flags. Parts of the yard ; Bunt : The short section of the yard between the ''slings'' that attach it to the mast. ; Quarters : The port and starboard quarters form the bulk of the yard, extending from the slings to the fittings for the lifts and braces. ; Yardarms : The outermost tips of the yard: outboard from the attachments for the lifts. Note that these terms refer to stretches of the same spar, not to separate component parts. Controlling the yard The yard can rotate around the mast to allow the direction of the vess ...

Carbon Fiber Testing
Carbon fiber testing is a set of various different tests that researchers use to characterize the properties of carbon fiber. The results for the testing are used to aid the manufacturer and developers decisions selecting and designing material composites, manufacturing processes and for ensured safety and integrity. Safety-critical carbon fiber components, such as structural parts in machines, vehicles, aircraft or architectural elements are subject to testing. Introduction Carbon fiber reinforced plastic and reinforced polymers are gaining importance as light-weight material. There are various disciplines for material testing that especially apply to carbon fiber materials. Most common are destructive tests, such as stress, fatigue and micro sectioning tests. There are also methods that allow non-destructive testing (NDT), so the material can be still be used after testing. Common methods are ultrasonic, X-ray, HF Eddy Current, Radio Wave testing or thermography. Additionally, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
