Epidemiological studies have identified associations between mortality and changes in concentration of particulate matter. These studies have highlighted the public concerns about health effects of particulate air pollution. Modeling fine particulate matter PM2.5 exposure risk and monitoring day-to-day changes in PM2.5 concentration is a critical step for understanding the pollution problem and...

Spatial discontinuity often causes poor accuracy when a single model is used for the surface modeling of soil properties in complex geomorphic areas. Here we present a method for adaptive surface modeling of combined secondary variables to improve prediction accuracy during the interpolation of soil properties (ASM-SP). Using various secondary variables and multiple base interpolation models, A...

Estuarine ecosystems are becoming increasingly altered by the concentration of human populations near the coastline, however a robust indicator of this change is lacking. We developed an index of waterbird community integrity (IWCI) and tested its sensitivity to anthropogenic activities within 28 watersheds and associated subestuaries of Chesapeake Bay, USA. The IWCI was used as a tool to gain ...

Let A and B be simple separable nuclear monotracial C⁎-algebras, let α β strongly outer actions of a countable discrete amenable group Γ on B, respectively. In this paper, we show that α⊗idW A⊗W β⊗idW B⊗W are cocycle conjugate where W is the Razak-Jacelon algebra. Also, characterize such by using fixed point subalgebras Kirchberg's central sequence C⁎-algebras.

Resumo: A interpolação espacial é o processo de prever o valor de atributos em locais não amostrados a partir de medições realizadas em localizações diversas de uma determinada região [Burrough, McDonnell, 1998]. Rever e comparar os interpoladores determinísticos espaciais usados em Sistemas de Informação Geográficos (GIS) como a B-Spline, Fourier, TIN, IDW e as superfícies de tendência polinom...

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...

Because of the associativity of fusion products ⊠, the above hypothesis is equivalent to the condition that for each irreducible module W , there is an irreducible module W̃ such that HomV (W̃ ⊠ W,V ) 6= 0. In the previous paper [6], we have introduced a concept of ”Semi-Rigidity” and then proved that if W is semi-rigid, then W is flat for the fusion products ⊠, that is, 0 → W ⊠ A → W ⊠ B → W ⊠ C...
