Comparative tribology studies of hard ceramic and composite metal-DLC coatings in sliding friction conditions
(1995)The design of anti-friction coatings able to perform well in different wear conditions without lubricants requires a combination of adequate hardness and toughness, good adhesion, a low friction coefficient and a low wear ...

Comparison of free surface polarization of NiMnSb and Co2 MnSi
(2006)We present a systematic study of the polarization of the transport current from a variety of NiMnSb and Co2 MnSi thin films and bulk material using point contact Andreev reflection spectroscopy. The simple analysis suggests ...

Composite DLC-metal/metal-carbide coatings produced by electron enhanced unbalanced magnetron sputtering
(1997)Composite coatings consisting of metal containing diamond like carbons were produced by unbalanced magnetron sputtering in a closed field magnetic configuration. Targets of Pta and W were poisoned with acetylene during the ...

Compression molding of semi-concentrated fiber suspensions: Flow and fiber orientation
(Publ by ASME, 1993)The focus of this paper is compression molding of semi-concentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...

Compression molding using a generalized eulerian–lagrangian formulation with automatic remeshing
(1992)A generalized Eulerian‐Lagrangian approach is used to study the compression molding of viscoelastic polymers. The complete, unsteady, two‐dimensional equations of motion are used in the analysis. The White–Metzner model ...

Computation of complex terrain turbulent flows using hybrid algebraic structure-based models (ASBM) and LES
(2016)In this work, we revisit the coupling of the Algebraic Structure-Based Model with popular two-equation eddy viscosity models (EVM). We consider both the v2 − f model and variants of the κ-ω model. Our aim is to explore the ...

Computational fluid dynamics (CFD) Simulations of aerosol deposition in the lungs
(TSFP-9, 2015)In the current study, Large Eddy Simulations (LES) are used to investigate the transport and deposition of inhaled aerosol particles (dp = 0.1, 0.5, 1, 2.5, 5, 10 μm) in a realistic geometry of the human airways under ...

Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation
(2008)The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...

A consistent velocity approximation for variable-density flow and transport in porous media
(2013)Using a finite-volume nodal-based code, we introduce a new consistent numerical scheme for approximating the seepage velocity in variable-density flow in porous media. It has been known from previous works that the lack ...

Constraints on the temperature dependence of the magnetic penetration depth of superconducting Bi2Sr2CaCu2O8+x from measurements of the low-temperature specific heat
(1992)We have measured the low-temperature (2"10 K) specific heat of polycrystalline Bi2Sr2CaCu2O8+x in zero applied field and in an applied magnetic field of 1 T. We find no field-induced enhancement of the specific heat, to ...

Contrast-enhanced 3D ultrasound in the radiofrequency ablation of liver tumors
(2008)Liver metastases and hepatocellular carcinomas are two of the most common causes of cancer deaths in the world. Radiofrequency ablation (RFA) is a well recognized, effective and minimally invasive means of treating malignant ...

Contrast-enhanced ultrasound to ultrasound fusion during microwave ablation: feasibility study in a perfused porcine liver model
(2019)To obtain a complete response with thermal ablation, the margin and entire tumor volume must be treated. Real-time ultrasound visualization is limited during ablation due to gas production. This study assesses the feasibility ...

The contribution of active and inactive structures to the statistics of a turbulent pipe flow
(2017)The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...
