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...

Unconventional gas drilling (UGD) has enabled extraordinarily rapid growth in the extraction of natural gas. Despite frequently expressed public concern, human health studies have not kept pace. We investigated the association of proximity to UGD in the Marcellus Shale formation and perinatal outcomes in a retrospective cohort study of 15,451 live births in Southwest Pennsylvania from 2007-2010...

◮ We study Scrape-Off Layer (SOL) turbulence through simulations that evolve the plasma dynamics as the interplay of plasma source from the core, perpendicular transport, and losses at the limiter plates ◮ We identify the SOL turbulence regimes, defining the regions of existence of the Ballooning Modes [resistive (RBM) and inertial (IBM)] and the Drift Waves [resistive (RDW) and inertial (IDW)]...
