This means that first LCI data are calculated within a plant vertically, and then the resulting vertical values are aggregated across the plants. For either approach, the inventory of exchanges can be mapped to the associated inventory ...

... n is the number of simulations , cov is the coeverage eg 0.95 , mn is the mean and sd the sd of the simulated data ... sd ) ## calculate n sd's of size r ucic - means - qt ( ( 1 - сov ) / 2 , r - 1 ) * sd / sqrt ( r ) lci < -means + ...

Users can never gain access to the LCI data or metadata contained in the database. Rather, this information can only be used through an ... The two distinct advantages of Athena come from the fact that it is free, which means LCA can ...

What does this mean for PLA's LCI? We'll have to collect data and project it. We have analyzed Cargill's wet-milling operation as well as our lactic acid and PLA processes and converted the data for use in our LCI. Our raw data are ...

Emission models and LCI data: When primary data on fossil fuel use are to be collected, an existing transport process shall be modified to ensure ... Transport means and capacity There is wide array of possible means of transport with a ...

Within-test repeatability is well documented for LCI, with reported coefficient of variations of 3–8% in health and disease [21, 25, 27, 29]. Limited data are available over longer time periods. There was no change in mean LCI among ...

This is due to the use of data from different periods, from different geographic locations (was the aluminum made here or ... In the approach, DQIs are developed for all the data elements of an LCI model to arrive at a mean and standard ...

The performance of the two procedures is compared on the basis of 1500 simulations . n = = = = library ( mytnorm ) 250 ... 2 ) / sqrt ( n ) } mean ( R ) ; shapiro.test ( s ) ; shapiro.test ( R ) length ( which ( LCI < rho & UCI > rho ) ...

For example, if a unit process in the LCI database requires a novelty chemical, and no data is available to model the ... Consequential Aggregated LCI Data in LCI Databases The aggregation of LCI data can mean different things.

This use of subsamples affords a statistical definition of " failure of the vegetative cover " by a two - stage ... ( sin The lower confidence interval ( L.C.I. ) for the grand mean can then be calculated as follows C.I = t tos MS WII ...
