Method for Assessing the Fidelity of Optical Diffraction Tomography Reconstruction Methods

open access: yes, 2019
We use a spatial light modulator in a diffraction tomographic system to assess the accuracy of different refractive index reconstruction algorithms. Optical phase conjugation principles through complex media, allows us to quantify the error for different

Effect of hyperviscosity on the Navier-Stokes turbulence

open access: yes, 2010
In this paper we modified the Navier-Stokes equations by adding a higher order artificial viscosity term to the conventional system. We first show that the solution of the regularized system converges strongly to the solution of the conventional system ...

How to use Kepler’s first and second laws in a geo-heliocentric system? Ask G.B. Riccioli

open access: yesArchive for History of Exact Sciences
The Jesuit astronomer Giovanni Battista Riccioli (1598--1671) developed a kinematic and geo-heliocentric astronomical model capable of integrating the innovations spotted by the telescope after 1609. He tried to explain why planets move around the Earth, what are the causes of their irregular circuits, and more generally he tried to find a general law ...

A double-edged sword: Use of computer algebra systems in first-year Engineering Mathematics and Mechanics courses [PDF]

open access: yes, 2019
Many secondary-level mathematics students have experience with graphical calculators from high school. For the purposes of this paper we define graphical calculators as those able to perform rudimentary symbolic manipulation and solve complicated ...

Using the disperse system formalism, DSF, to determine the first two classes of complex suspensions

open access: yes, 2022
The "disperse system formalism" (DSF) can be used to describe the structure of physical and chemical systems at any scale. It is particularly useful for describing the microstructure of colloidal systems that are ubiquitous in food. Adapting a computer program that was already used for the study of complex gels, the whole set of possible suspensions ...

How to use the first and second order sensitivities of steady-state solutions to water distribution systems

open access: yes
A hydraulic model can be of considerable benefit to those responsible for the design and operation of drinking water systems. In the contemporary era, it is imperative that water distribution systems are operated in a more sober manner, in a sustainable and resilient fashion, to combat the effects of global warming and to mitigate natural and ...
