Comparison of LAAS B-Values with Linear Model Optimum B-Values
Navigation, 2000The accuracy of the GPS Local Area Augmentation System (LAAS) is achieved by using pseudorange corrections in the LAAS ground reference system to form estimates of the signal-in-space portion of the navigation system error (NSE). The LAAS integrity monitor ensures that these pseudorange correction error do not exceed a given value.

Physical background on estimating b value
Acta Seismologica Sinica, 1997The G-R relation lgN=a-bM (1954) is an empirical formula used widely in the seismicity research. But the linearity of b curves has great difference in different time and space domains. An interested question in this paper is that in how large a space-time-strength domain the b value has certain physical connotation.

B-value and Optical Fiber Lifetime
MRS Proceedings, 1998AbstractIn this work we analyze the existing literature relating to the B-value and the inert strength measurements. The weak flaw statistic model for fiber lifetime estimation is considered with regard for the two-region crack growth.

The B-Value: A Tool for Monitoring Data
Biometrics, 1988This paper considers the problem of monitoring slowly accruing data from a nonsequentially designed experiment. We describe the use of the B-value, which is a transformed Z-value, for the calculation of conditional power. In data monitoring, interim Z-values do not allow simple projections to the end of the study.

Local b-values related to seismicity
Tectonophysics, 1974Abstract To find a method by which the Caracas earthquake of July 29, 1967 could have been foreseen, a total of thirteen years of continuous seismographic records, recorded at the Seismological Institute Caracas (CAR), have been used to summarize the local seismic activity, in function of time and magnitude.

Seismic magnitudes, entropy and b-value
Acta GeophysicaHow seismic magnitudes are distributed is important for estimating stress levels in seismic hazard studies, and two methods of characterizing the magnitude distribution are through the Gutenberg-Richter b-value, or equivalently through , and through the information entropy.

Complexity of Hydraulic Fractures – The B-value
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010The distribution of moment magnitudes for a hydraulic fracture treatment is related to the complexity of the fracture network through the slope of the frequency-magnitude distribution, known as the b-value. Characterizing this complexity relates to effective field drainage and can be used to calibrate predictions of fracture-mechanical models. As the b-

Proceedings, 2013
In this paper we establish relations between the fractal distribution of elastic parameters, stress field variations and the Gutenberg-Richter b-value of earthquakes. We extract information about elastic parameter distribution from sonic well logs to create an elastically heterogeneous 3D random medium with a fractal spatial correlation function. Using

High-B-Value Diffusion-Weighted MRI in Colorectal Cancer
American Journal of Roentgenology, 2006The purpose of this article is to evaluate the usefulness of high-b-value diffusion-weighted MRI (DW-MRI) in the detection of colorectal adenocarcinoma.High-b-value DW-MRI allows detection of colorectal adenocarcinoma with a high sensitivity and specificity.
