A Data‐Centric Approach to Quantifying the Forward and Inverse Relationship Between Laser Powder Bed Fusion Process Parameters and as‐Built Surface Roughness of IN718 Parts

Advanced Intelligent Systems
Laser powder bed fusion (PBF‐LB) is an additive manufacturing (AM) technology for producing complex geometry parts. However, the high cost of post‐processing coarse as‐built surfaces drives the need to control surface roughness during fabrication.

Scotogenic inverse seesaw model of neutrino mass

Physics Letters B, 2014
A variation of the original 2006 radiative seesaw model of neutrino mass through dark matter is shown to realize the notion of inverse seesaw naturally.

Inverse Demand Systems for Composite Liquid Assets: Evidence from China [PDF]

This paper applies the concept of inverse demands and its related scale and substitution effects to model the demand for liquid assets in China. We also propose a new model, termed the Modified Almost Ideal Inverse Demand System (MAIIDS), which nests the

Analysing recent spatial and temporal atmospheric methane variations using forward and inverse modelling [PDF]

, 2011
The TOMCAT 3-D chemical transport model (CTM) has been used to investigate the cause of recent variations in global atmospheric methane (CH4), focusing on examining changes in the balance of sources and sinks of the species.

An inverse dynamics method for railway vehicle systems

Transport, 2014
The wheel–rail action will obviously be increased during the vehicles in high-speed operation state. However, in many practical cases, direct measurement of the wheel–rail contact forces cannot be performed with traditional procedures and transducers. An

Inverse problem for the Earth's core evolution model

Russian Journal of Earth Sciences, 2020
The size and the age of the inner core impose constraints in modeling of the Earth's core evolution. The origin of the solid core corresponds to the change in convection regime in the core and, correspondingly, to the change in the magnetic field ...

"Uniform Measures On Inverse Limit Spaces" [PDF]

Motivated by problems from dynamic economic models, we consider the problem of defining a uniform measure on inverse limit spaces. Let f be a function from a compact metric space X into itself where f is continuous, onto and piecewise one-to-one.

Calibrate complex fracture model for subsurface flow based on Bayesian formulation

Petroleum Science, 2019
In practical development of unconventional reservoirs, fracture networks are a highly conductive transport media for subsurface fluid flow. Therefore, it is crucial to clearly determine the fracture properties used in production forecast.
