It is not always clear how to adjust for control data in causal inference, balancing the goals of reducing bias and variance. We show how, a setting with repeated experiments, Bayesian hierarchical modeling yields an adaptive procedure that uses determine much adjustment perform. The result novel analysis increased statistical efficiency compared default based on difference estimates. demonstra...

This work numerically evaluates the role of advancing velocity on water entry rigid wedges, highlighting its influence development underpressure at fluid–structure interface, which can eventually lead to fluid detachment or cavity formation, depending geometry. A coupled FEM–SPH numerical model is implemented within LS-DYNA, and three types asymmetric impacts are treated: (I) symmetric wedges w...

development of a numerical model which describes launching of offshore jackets from barge is presented in this paper. in this model, in addition to capabilities of commercial softwares, water entry forces on jacket members and an implicit newmark solution technique are included. the results are in general agreement with other numerical software’s available (sacs). fluid forces acting on jacket ...

in order to design and manufacturing some postharvest equipment, determination of some hydrodynamic properties of crops are necessary. the quality of products in global and local markets can be increased by applying these properties and receive economical benefits. for these purpose, two local varieties of apples in the east azerbaijan province, iran(asheghi and gare yapraq)were selected.ashegh...

measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...
