Vibration-Induced Property Change in the Melting and Solidifying Process of Metallic Nanoparticles

open access: yesNanoscale Research Letters, 2017
Tuning material properties in the 3-D printing process of metallic parts is a challenging task of current interests. Much research has been conducted to understand the effects of controlling parameters such as the particle geometry (size and shape ...

Influence of Failure Strain of Different Aluminium Alloys on Dynamic Problems

open access: yesEngineering Transactions, 2014
In this work an experimental-numerical methodology is devised for analyzing ductile fracture of two aluminum alloys under different values of stress triaxiality (0.2 ≤ η ≤ 1.2) and Lode parameter (−1 ≤ μ ≤ 0).

Variational Integrators in Holonomic Mechanics

open access: yesMathematics, 2020
Variational integrators for dynamic systems with holonomic constraints are proposed based on Hamilton’s principle. The variational principle is discretized by approximating the generalized coordinates and Lagrange multipliers by Lagrange polynomials, by ...

An eigenscrew analysis of mechanism compliance [PDF]

open access: yesProceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002
Determination of the magnitudes and directions of the constraints of a mechanical system can be achieved by finding the basis of the system's characteristics compliance matrix. When little is known about the geometry of the system, conventional methods cannot be used to calculate the system's compliance matrix. A new method has been developed that uses

Analysis of reward mechanism for quizmarket

open access: yesCoRR, 2023
A reward algorithm is needed for games which rewards risk, i.e. early play, and extends the longevity of a reward pool. This would allow a higher number of players and greater engagement. I created a reward mechanism that rewards risk, lasts longer, and is more profitable than existing mechanisms. I also implemented an algorithm within the mechanism to

A novel Hamiltonian-based method for two-dimensional transient heat conduction in a rectangle with specific mixed boundary conditions

open access: yesJournal of Thermal Science and Technology, 2017
A novel Hamiltonian-based method is introduced to the two-dimensional (2-D) transient heat conduction in a rectangular domain with partial temperature and partial heat flux density on one boundary.

Leukemia and Exposure to Potential Benzene Sources in Children From the Mexico City Metropolitan Area, 2010–2021: A Geospatial Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

An Analytic Model of Transient Heat Conduction for Bi-Layered Flexible Electronic Heaters by Symplectic Superposition

open access: yesMicromachines, 2022
In a flexible electronic heater (FEH), periodic metal wires are often encapsulated into the soft elastic substrate as heat sources. It is of great significance to develop analytic models on transient heat conduction of such an FEH in order to provide a ...
