The parameters of the constitutive models used in design rockfill dams are associated with a high degree uncertainty. This occurs because comprised numerous zones, each different soil materials, and it is not feasible to extract materials from such structures accurately ascertain their behavior or respective parameters. general approach involves laboratory tests using small material samples emp...

Fuzzy set theory has shown potential for reducing uncertainty as a result of data sparsity and also provides advantages quantifying gradational changes like those pollutant concentrations through fuzzy clustering based approaches. The ability to lower the sampling frequency perform laboratory analyses on fewer samples, yet still produce an adequate distribution map, would reduce initial cost ne...

Various studies are currently underway on PM (Particulate Matter) monitoring in view of the importance air quality public health management. Spatial interpolation has been used to estimate concentrations due that it can overcome shortcomings station-based and provide spatially continuous information. However, is affected by a combination several factors, only considers spatial relationship betw...

To realize the in-motion alignment of strapdown inertial navigation system (SINS) under geographic latitude uncertainty, we propose a estimation and method based on integral dynamic window polynomial fitting (IDW-PF) improved Kalman filter (IKF). First, (IDW) is designed to smooth out high-frequency line motion interference accelerometer noise. Second, specific force performed for cubic (PF) wi...

Sparse interpolation refers to the exact recovery of a function as short linear combination basis functions from limited number evaluations. For multivariate functions, case monomial is well studied, now exponential functions. Beyond Chebyshev polynomial obtained tensor products univariate polynomials, theory root systems allows define variety generalized polynomials that have connections topic...

In alpha-1 antitrypsin deficiency (AATD), the Z allele is present in 98% of cases with severe disease, and knowledge of the frequency of this allele is essential from a public health perspective. However, there is a remarkable lack of epidemiological data on AATD worldwide, and many of the data currently used are outdated. Therefore, the objective of this study was to update the knowledge of th...
