Lower bound - Open Access .click

IEEE Transactions on Image Processing, 2020
The visibility of an image captured in poor weather (such as haze, fog, mist, smog) degrades due to scattering of light by atmospheric particles. Single image dehazing (SID) methods are used to restore visibility from a single hazy image.

3D concrete printing: A lower bound analytical model for buildability performance quantification

Automation in Construction, 2019
Concrete structures are 3D printed in the plastic state, therefore emphasis should be placed on the rheological characterisation of these materials to ensure that they are appropriate for 3D printing as well as for quality control.

Are Negative Supply Shocks Expansionary at the Zero Lower Bound?

Journal of Political Economy, 2019
The standard new Keynesian model predicts that economies behave differently at the zero lower bound: completely wasteful government spending or forward guidance is very stimulative, and capital destruction or oil supply shocks are expansionary. I provide

Lower bounds

1992
Abstract We now tum to the problem of finding lower bounds for Poisson approximation. Although the Stein–Chen method is widely applicable, it would be much less interesting if it did not give accurate estimates, at least in the sense that the upper bounds it gave were of the right order of magnitude.
