A Review of Spatter in Laser Powder Bed Fusion Additive Manufacturing: In Situ Detection, Generation, Effects, and Countermeasures [PDF]

open access: yes, 2022
Spatter is an inherent, unpreventable, and undesired phenomenon in laser powder bed fusion (L-PBF) additive manufacturing. Spatter behavior has an intrinsic correlation with the forming quality in L-PBF because it leads to metallurgical defects and the ...

Note on the Regularity of Nonadditive Measures

open access: yesJournal of Applied Mathematics, 2013
We consider the regularity for nonadditive measures. We prove that the non-additive measures which satisfy Egoroff's theorem and have pseudometric generating property possess Radon property (strong regularity) on a complete or a locally compact ...

Perturbation for the Group Inverse in a Banach Algebra

open access: yesAxioms
We present new additive results for the group inverse in a Banach algebra under certain perturbations. The upper bound of ∥(a+b)#−ad∥ is thereby given. These results extend the main results presented by Liu, Qin, and Wei.

On additive properties of general sequences

open access: yesDiscrete Mathematics, 1994
The authors give a survey of their papers on additive properties of general sequences and they prove several further results on the range of additive representation functions and on difference sets. Many related unsolved problems are discussed. Let \(\mathbb{N}= \{1, 2,\dots\}\) and \(\mathbb{N}_0= \mathbb{N}\cup \{0\}\). For \(A\subseteq \mathbb{N}_0\)

ADDITIVE COVERS AND THE CANONICAL BASE PROPERTY

open access: yesThe Journal of Symbolic Logic, 2022
AbstractWe give a new approach to the failure of the Canonical Base Property (CBP) in the so far only known counterexample, produced by Hrushovski, Palacín and Pillay. For this purpose, we will give an alternative presentation of the counterexample as an additive cover of an algebraically closed field.

Symplectic Integration of Hamiltonian Systems with Additive Noise [PDF]

open access: yes, 2002
Hamiltonian systems with additive noise possess the property of preserving symplectic structure. Numerical methods with the same property are constructed for such systems.

Data Cost Games as an Application of 1-Concavity in Cooperative Game Theory

open access: yesJournal of Applied Mathematics, 2014
The main goal is to reveal the 1-concavity property for a subclass of cost games called data cost games. The motivation for the study of the 1-concavity property is the appealing theoretical results for both the core and the nucleolus, in particular ...

Optimization of process-property relations of 3D printed ceramics using extrusion-based additive manufacturing [PDF]

open access: yes, 2021
The capability and applicability of additive manufacturing have mesmerized the entire manufacturing world. One major technique of additive manufacturing is extrusion-based additive manufacturing (EAM), which has been recently employed for the rapid ...

Hopfian additive groups of rings [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
A group is called Hopfian  if it is not isomorphic to any of its proper factor groups, or, equivalently, any of its epimorphisms on itself is an isomorphism, i.e., an automorphism. This property was first proved by the Swiss mathematician H.

Layered co-continuous structure in bone scaffold fabricated by laser additive manufacturing for enhancing electro-responsive shape memory properties

open access: yesJournal of Materials Research and Technology
Porous scaffold based on electro-responsive shape memory polymers (ESMPs) possesses great potential applications in minimally invasive surgery for bone defect repair because it provides the ability for remote control and internal heating.
