The Density Probability Distribution in Compressible Isothermal Turbulence: Solenoidal versus Compressive Forcing

, 2008
The probability density function (PDF) of the gas density in turbulent supersonic flows is investigated with high-resolution numerical simulations. In a systematic study, we compare the density statistics of compressible turbulence driven by the usually ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Analysis of the Influence of Sugarcane Bagasse Fibers in the Natural State on the Mechanical Properties of Concrete

Journal of Natural Fibers
This study aims to analyze the influence of sugarcane bagasse fiber (SCBF) without treatment on concrete and its impact on carbon footprint production. This review studies the impact of SCBF on the compressive strength, flexural strength, direct tensile ...

Nonlinear Basis Pursuit

, 2013
In compressive sensing, the basis pursuit algorithm aims to find the sparsest solution to an underdetermined linear equation system. In this paper, we generalize basis pursuit to finding the sparsest solution to higher order nonlinear systems of ...

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

The effect of antifungal oral gel and ozonated water on tensile and compressive strength of two types of denture base materials: in-vitro study

Journal of the Arab Society for Medical Research
Background/aim Debris accumulation beneath the dentures initiates countless difficulties such as inflamed oral mucosa and denture stomatitis. Denture stomatitis is a prevalent pathologic illness that is commonly linked to Candida albicans.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Imaging via Compressive Sampling [Introduction to compressive sampling and recovery via convex programming] [PDF]

, 2008
There is an extensive body of literature on image compression, but the central concept is straightforward: we transform the image into an appropriate basis and then code only the important expansion coefficients.

Compressive Identification of Linear Operators

, 2011
We consider the problem of identifying a linear deterministic operator from an input-output measurement. For the large class of continuous (and hence bounded) operators, under additional mild restrictions, we show that stable identifiability is possible ...
