Cagniard de la Tour showed in 1822 that there is a critical temperature above which a single
substance can only exist as a fluid and not as either a liquid or gas. He heated substances, …

… To complement the theme of this month’s issue, John R Williams looks at the Declaration of
Helsinki and how it has evolved over time. The original declaration is reproduced here in full …

Over the last two decades, lattice Boltzmann methods have become an increasingly popular
tool to compute the flow in complex geometries such as porous media. In addition to single …

In this paper we describe how wavelets may be used to solve partial differential equations.
These problems are currently solved by techniques such as finite differences, finite elements …

This paper discusses advances in interactive discrete element simulation for use in
computer‐aided concurrent design. We highlight the computational problems of creating a ‘virtual …

A coupled numerical method for the direct simulation of particle‐fluid systems is formulated
and implemented. The Navier‐Stokes equations governing fluid flow are solved using the …

The aim of this paper is to provide an introduction to the subject of wavelet analysis for
engineering applications. The paper selects from the recent mathematical literature on wavelets …

This paper addresses the problem of contact detection in discrete element multibody dynamic
simulations. We present an overview of the problem and a detail description of a new …

As advanced metering infrastructure (AMI) is responsible for collecting, measuring, and
analyzing energy usage data, as well as transmitting this information from a smart meter to a data …

In this paper we quantify the influence of geometry and distribution of surface roughness to
the directional anisotropy of fluid flow and transport properties of a single fracture. …
