Climatic estimates of average and probable irrigation requirements and of seasonal drainage in Canada

Journal of Hydrology, 1970
Abstract This paper demonstrates the use of published information on average and probable irrigation requirements which were estimated by means of a meteorological budgeting technique from 30-year daily climatic records. This information, available for 59 stations across Canada, is useful for planning irrigation systems and interpretations of climate

Endoscopic requirements of colorectal cancer screening programs in average-risk population. Estimation according to a Markov model

Gastroenterología y Hepatología, 2008
Although colorectal cancer (CRC) screening strategies are quite common in the United States, their systematic introduction in Europe has been delayed until the year 2008. To estimate endoscopic requirements of four different CRC screening strategies (annual and biennial fecal occult blood testing (FOBT), flexible sigmoidoscopy every 5 years, and ...

Temporal sampling requirements for estimation of long-term average sound levels in the vicinity of airports

The Journal of the Acoustical Society of America, 1981
Community noise temporal sampling requirements in general, and in the vicinity of airports or other large noise producers in particular, are not well understood. Frequently, the purpose is to sample and estimate the true yearly Day/Night Average Sound Level (DNL) or Community Noise Equivalent Level (CNEL).

A Bound on the Precision Required to Estimate a Boolean Perceptron from Its Average Satisfying Assignment

SIAM Journal on Discrete Mathematics, 2006
A Boolean perceptron is a linear threshold function over the discrete Boolean domain {0,1}n. That is, it maps any binary vector to 0 or 1, depending on whether the vector's components satisfy some linear inequality. In 1961, Chow showed that any Boolean perceptron is determined by the average or "center of gravity" of its "true" vectors (those that are

Validation of a Novel Protocol for Calculating Estimated Energy Requirements and Average Daily Physical Activity Ratio for the US Population: 2005-2006

Mayo Clinic Proceedings, 2013
To validate the PAR protocol, a novel method for calculating population-level estimated energy requirements (EERs) and average physical activity ratio (APAR), in a nationally representative sample of US adults.Estimates of EER and APAR values were calculated via a factorial equation from a nationally representative sample of 2597 adults aged 20 and 74 ...

Criteria for Estimating the Required Average Strength f'cr to Comply with the Specified Compressive Strength f'c

ACI Materials Journal, 1987
The ACI Building Code criteria for estimating the required average strength f'cr is evaluated using actual field data. Basically, the current criteria specify that the required average strength f'cr should be larger than the specified compressive strength f'c by a certain amount.

Despite the Introduction of Mandatory Folic Acid Fortification, Australian Women of Childbearing Age may not obtain the Estimated Average Requirements for Folate

The FASEB Journal, 2016
Background Despite the importance of folate in reducing the risk of Neural Tube Defects (NTD's) and the widespread introduction of mandatory folic acid fortification, there remains a lack of data on the sources where child bearing age women are obtaining their folate requirements.

Stone Burden in an Average Swedish Population of Stone Formers Requiring Active Stone Removal: How Can the Stone Size Be Estimated in the Clinical Routine?

European Urology, 2003
To get information on the distribution of stone burdens in an average and representative group of Swedish stone forming patients requiring active removal of stones from the kidneys or ureters and to compare different methods for assessing the stone burden.A computerised device was used to measure the total stone surface area (A(measured)) of 599 stone ...

An estimation of the residential space heating energy requirement in Cyprus using the regional average specific heat loss coefficient

Energy and Buildings, 2012
Abstract The energy losses in residential space heating constitute a large portion of the wasted energy. The excess energy consumed for heating of a house or a region is a good indicator to show the amount of energy wasted due to improper construction and poor insulation.

Estimating a Boolean Perceptron from Its Average Satisfying Assignment: A Bound on the Precision Required

A boolean perceptron is a linear threshold function over the discrete boolean domain {0, 1}n. That is, it maps any binary vector to 0 or 1 depending on whether the vector's components satisfy some linear inequality.
