Negative local resistance caused by viscous electron backflow in graphene
Graphene hosts a unique electron system in which electron-phonon scattering is extremely weak but electron-electron collisions are sufficiently frequent to provide local equilibrium above the temperature of liquid nitrogen, under which electrons can behave as a viscous liquid and exhibit hydrodynamic phenomena similar to classical liquids.

Superballistic flow of viscous electron fluid through graphene constrictions
Graphene systems are clean platforms for studying electron–electron (e–e) collisions. Electron transport in graphene constrictions is now found to behave anomalously due to e–e interactions:Expand
Flammability Limits of Hydrogen-Oxygen-Diluent Mixtures
Flammability limits of hydrogen-oxygen-diluent mixtures were determined in a 5-cm diameter, 1.8-m long tube, for upward, downward and horizontal prop agation of the flame. It was found that forExpand
Vented Turbulent Combustion of Hydrogen-Air Mixtures in A Large Rectangular Volume
*Turbulent combustion experiments were performed in a 120-m 3 vented vessel of rectangular geometry to determine the effects of turbulence on combustion. The study included hydrogen concentrationsExpand
Transient Finite Element Analysis of Tire Dynamic Behavior
Abstract Dynamic behavior of a pneumatic tire is simulated by use of an explicit finite element (FE) code. Different parts of the tire and their corresponding material properties are taken intoExpand
Large-scale dust explosion experiments to determine the effects of scaling on explosion parameters
Abstract Experiments were performed in a 1.5-m-diameter, 5.7-m-high (volume, 10.3 m3) cylindrical vessel with cornstarch and coal dusts for comparison with explosion parameters in smaller vessels.Expand
A study of the relationship between Magic Formula coefficients and tyre design attributes through finite element analysis
Pacejka's Magic Formula Tyre Model is widely used to represent force and moment characteristics in vehicle simulation studies meant to improve handling behaviour during steady-state cornering. TheExpand
Finite element modelling of piston-ring dynamics and blow-by estimation in a four-cylinder diesel engine
Abstract This paper presents the results of the simulation of piston-ring behaviour in a four-cylinder diesel internal combustion engine, using explicit finite element analysis. The finite elementExpand
Numerical modeling of stress induced martensitic phase transformations in shape memory alloys
Abstract Phenomenological models of shape memory behavior are based on either continuum hypothesis (macroscopic) or on volume averages over a representative volume element consisting of severalExpand
Fracture mechanics approaches to coating strength evaluation
Abstract The incidence of mechanical failure of flame sprayed molybdenum coating on piston rings prompted development of reliable methods of characterising and improving bond strengths. A method ofExpand
