Agglomerates of fine particles are frequently encountered in a wide range of important chemical, biotechnical, medical and materials processing applications including pharmaceutical, polymer, mining, and food technologies. Often, the processing goal is the dispersion of the agglomerate into smaller clusters (or if possible, into its constituent particles) and distribution of these finely divide...

Robot skill acquisition can be conceptualized as a task of identifying patterns in a spatio-temporal sensory feature space. Skills can be mathematically learned through identifying mappings from sensory signals into Qualitative States (QS), construction of a QS skill automaton, and the detection of motor or output commands that transition the model from the present QS to the next QS. In this pa...

There has been growing interest in the modelling of proton exchange membrane fuel cells (PEMFC). While some steady-state models have been proposed, literature is scarce in PEMFC two-phase dynamic models and transient studies. Typical dynamic models for the fuel cell are empirical current-voltage dynamic models. The internal transients associated with reactant and product species and other compo...

Only a few research papers have analysed the spatial distribution of economic activity in Ireland. There are a number of reasons for this, not least the fact that comprehensive data on the location of economic activity by sector across all sectors has not been available at the highly disaggregated spatial level. This paper firstly establishes the geographic distribution of employment at the 2 d...

Yes and no. These synthetic stones are in fact re-agglomerated materials. The process is explained in more detail later in the book. Basically, the principle is as follows: starting with a mineral substance such as eroded, disintegrated or naturally disaggregated rock – such as the limestone found everywhere in northern France – we give it a compact structure using a binder, a geological glue t...

This paper provides an overview on our recent investigations on the consolidation of hierarchy-structured nanopowder agglomerates and related applications to net-shaping nanopowder materials. Understanding the nanopowder agglomerate sintering (NAS) process is essential to processing of net-shaped nanopowder materials and components with small and complex shape. The key concept of the NAS proces...

Computational Fluid Dynamics (CFD) and Discrete Element Modelling (DEM) studies relevant to inhaled drug delivery are reviewed. CFD is widely used in device design to determine airflow patterns and turbulence levels. CFD is also used to simulate particles and droplets, which are subjected to various forces, turbulence and wall interactions. These studies can now be performed routinely because o...

Abstract Using the data of five agglomerate-fog-related traffic accidents during 2014–2017 and fog-related expressway 2013–2018 assessed by Anhui provincial authorities corresponding meteorological observation data, this article analyzes spatio-temporal characteristics, geographical environment weather background in detail identifies characteristics changes terms visibility, humidity, temperatu...

The drum agglomeration of nickel laterite and gold ores has been optimized through the design of experiments (DOE) using a Taguchi L16 (45) orthogonal array to determine the optimum conditions for maximizing average agglomerate size and minimizing the amount of fines. The effects of controllable operating factors including moisture content (nickel laterite ore: 34-37%; gold ore: 7-10%), retenti...
