ASSESSMENT OF LANDFILL GAS (LFG) ENERGY POTENTIAL BASED ON ESTIMATES OF LFG MODELS

Estimation of gas emission released from a municipal solid waste landfill site through a modeling approach: A case study, Sanandaj, Iran

Sanitary landfill is the common strategy for municipal solid waste management in developing countries. Anaerobic decomposition of disposed wastes in landfill under favorable conditions will lead to the landfill gas (LFG) emissions, considering as emerging air pollutants. The emission of greenhouse gases, including methane, resulting from municipal solid waste disposal and treatment processes ar...

Encoding LFG f-structures in the TL-LFG type system

Type-Logical Lexical Functional Grammar is a new syntactic framework similar in nature to Type-Logical Categorial Grammar, but with a distinct Lexical Functional Grammar flavour. It is the overall setup of TLLFG that makes it a close relative of TLCG, but it is the information encoded in the type system that brings it even closer to LFG. The encoding of f-structure information in the TL-LFG typ...

A Method for Estimating the Rate of Landfill Gas Generation By Measurement and Analysis of Barometric Pressure Waves

Estimation of the rate of landfill gas (LFG) generation is needed (1) to satisfy USEPA and state regulatory requirements associated with estimating non-methane organic carbon emissions; (2) to assess the impact of landfill-generated methane on global warming; (3) as part of the design of LFG and methane control systems; and (4) to provide information necessary to evaluate and design LFG-to-ener...

Experiments with Corpus-based LFG Specialization

Sophisticated grammar formalisms, such as LFG, allow concisely capturing complex linguistic phenomena. The powerful operators provided by such formalisms can however introduce spurious ambiguity, making parsing inefficient. A simple form of corpus-based grammar pruning is evaluated experimentally on two wide-coverage grammars, one Engiish and one French. Speedups of up to a factor 6 were obtain...
