structural integrity of components in service. Techniques for embedding fiber optic sensors in metals‚ polymers‚ and ceramics have been investigated. Embedding optical fibers into metals is especially challenging because engineering alloys tend to exhibit high melting temperatures. In the present research an embedding sequence was developed capable of embedding fiber sensors into parts made of metal alloys with high melting temperatures. Fiber Bragg Grating (FBG) sensors were selected as the most promising

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities

heat-resistant glass in 1908. In 1912‚ this product was being reused to develop the shatterproof lanterns for the railroad. Their products were first used for scientific purposes and later for consumer cook-ware products. By realizing the improvement in optical glassmaking‚ Corning had started to produce the television tubes project and it made the TV affordable to the consumers’ market during 1970s. However‚ this project considered a steep loss in profit and productivity because of the competition from
