The detection of attacks and intrusions based on anomalies is hampered by the limits of specificity underlying the detection techniques. However, in the case of many critical infrastructure systems, domain-specific knowledge and models can impose constraints that potentially reduce error rates. At the same time, attackers can use their knowledge of system behavior to mask their manipulations, c...

The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation....

Bamboo raw feedstocks with large particle size (20−80 mesh) were subjected to a microwave liquefaction system, and the liquefied products were separated into biopolyols and liquefied residues. Biopolyols were first analyzed by gas chromatography mass spectrometry (GC−MS), and the main components were sugar derivatives with 2−4 hydroxyl groups and phenolic compounds derived from lignin. The resi...

LNG is an alternative fuel to replace diesel and gasoline. The use of as a has many advantages from various aspects. Besides having advantages, also disadvantages because it contains dangers in it. volatile material that easily flammable, which causes fires explosions. Environmental Risk Assessment (ERA) systematic method used measure the magnitude risk process product hazard human health ecolo...

a value chain is a series of events that takes a raw material and with each step adds value to it. global interest in the application of natural gas (ng) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. many technological solutions are currently considered on the market or in development, whic...
