TAILIEUCHUNG - Fiber Optics Illustrated Dictionary - Part 59

The Fiber Optics Illustrated Dictionary - Part 59 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary and precision metal components. Lapping film can prepare optical fiber surfaces for bonding by flattening joint surfaces polishing with progressively finer films and removing excess bond . epoxy . Water may be used as a lubricant laptop computer A low-weight battery-powered or combination battery AC-powered portable computer. Laptops fit easily on a lap airline tray train table or other support surface in common moving conveyances. They range in weight from about 3 to 7 pounds. Some people distinguish notebook computers as midrange between laptops and palmtops at about 2 to 4 pounds. Larger portable computers are called luggables or transportables and the smallest ones are called palmtops and programmable calculators. They weigh from a few ounces up to about 2 or 3 pounds. A laptop battery usually lasts about 2 to 6 hours and may be extended by using powersaver functions or turning off the monitor. Car lighter adapters may help power or recharge a laptop battery. Laptops are equipped with flat light low power monitors typically incorporating LED passive matrix active matrix or gas plasma components. The active matrix screens are brighter and easier to see in dim or bright lighting conditions than screens that depend upon optimal ambient lighting. Many laptops are equipped with PCMCIA Type I or Type II card slots so the user can add lower power compact peripherals such as extra memory cards fax modems network ports etc. USB and FireWire ports are also now common. LArc A data archiving program descended from LZSS developed by Lempel Ziv Storer and Szymanski and further optimized and extended in the late 1980s by Okumura and Miki. Kazuhiko Miki reworked Okumura s version of LZSS with Pascal and Assembler to create the archiving tool called LArc whose file handling was quick and compact. Huffman coding was later incorporated into the software by Yoshizaki to create an even faster and more popular version called LHarc. See LHarc. .
