SQT emission rates and landscape flux estimates are highly uncertain.
Development costs tend to increase with project complexity, and hence accurate cost estimates are highly desired during the early stages of development.
The cost to clean up the nuclear weapons complex has been put at $200 billion or more over several decades, but the technology for some parts of the work has yet to be developed, so the estimates are highly uncertain.
But the number of Hispanic and Asian-American graduates will increase sharply, according to projections by the Western Interstate Commission for Higher Education, whose demographic estimates are highly regarded by admissions officials.
In addition, we show that these cost estimates are highly dependent on some key system design parameters including the public safety capacity required and signal coverage reliability, which must therefore be well-defined in advance.
Results for the study area suggest that water yield estimates are highly sensitive to climate, especially in the lowlands, while nutrient export and retention estimates are overwhelmingly driven by land cover.
For the site in the Anhui province of China, where agricultural fields are very small (0.07 ha on the average), area estimates are highly sensitive to class definition thresholds even at the relatively fine resolution of 45 m.
We first establish that forward-looking estimates are the basis for most financial statement information and that some of these estimates are highly uncertain, which increases the challenges faced by auditors.
Acknowledging fault-lines in its new study, contracted to energy consulting firm Advanced Resources International Inc. (ARI), the EIA said: "These shale oil and shale gas resource estimates are highly uncertain and will remain so until they are extensively tested with production wells".
"Building weapons and expending them isn't the basis of sustained economic growth". The Pentagon is believed to have estimated a cost around $50bn, but independent economists say these kind of estimates are highly speculative, dependent on a large number of variables, and subject to all kinds of creative accounting possibilities.
But government analysts acknowledged that estimates are highly uncertain and depend on such factors as the price of oil and the pace of innovation on energy efficiency, carbon capture and sequestration, as well as how people and businesses respond to higher fossil-fuel prices.
