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...

We c a l l t he l a s t one an IDW method. Robots w i t h AK TRACT JDW ^ e g systems are w i d e l y used because, w i t h o u t any separa te s t e e r i n g mechanism, they can move to any p o i n t by a comb ina t ion of r e v o l v i n g and go ing s t r a i g h t . T h i s paper d iscusses how to c o n t r o l and d e s c r i b e t he smooth movement of a mob i le r o b o t wh ich has two ...

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...
