Abstract
Highlights that in spite of the notion generally held, that consumer durables are luxuries, the market displays some inertia comparable to that of non‐durables. Proposes that new analysis of the structure of the consumer‐durable markets leads to the concept that they have basic strengths that can only be temporarily violated. Distinguishes further between individual initial sales and statistical initial sales, also between individual replacement sales and statistical replacement sales. Closes by stating that consumers are not really affected by economic conditions, except in so far as they may postpone their purchases – particularly in the replacement sector.

Abstract
Purpose
This paper aims to construct smooth poly-ellipsoid shapes from synchrotron microcomputed tomography (SMT) images on sand and to develop a new discrete element method (DEM) contact detection algorithm.
Design/methodology/approach
Voxelated images generated by SMT on Colorado Mason sand are processed to construct smooth poly-ellipsoidal particle approximations. For DEM contact detection, cuboidal shape approximations to the poly-ellipsoids are used to speed up contact detection.
Findings
The poly-ellipsoid particle shape approximation to Colorado Mason sand grains is better than a simpler ellipsoidal approximation. The new DEM contact algorithm leads to significant speedup and accuracy is maintained.
Research limitations/implications
The paper limits particle shape approximation to smooth poly-ellipsoids.
Practical implications
Poly-ellipsoids provide asymmetry of particle shapes as compared to ellipsoids, thus allowing closer representation of real sand grain shapes that may be angular and unsymmetric. When incorporated in a DEM for computation, the poly-ellipsoids allow better representation of particle rolling, sliding and interlocking phenomena.
Originality/value
Method to construct poly-ellipsoid particle shapes from SMT data on real sands and computationally efficient DEM contact detection algorithm for poly-ellipsoids.

Abstract
The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.
