This paper describes a laser diffraction particle stzing technique applications and hardware improvements. With sound theoretical background, this technique finds itself competing in the particle sizing technology market with the introduction of Malvern model series 1800, 2600 and Master Sizer of which the first two models have been tested extensively. Correction schemes to overcome same basic ...

This paper is concerned with apparel sizing system design. One of the most important issues in the apparel development process is to define a sizing system that provides a good fit to the majority of the population. A sizing system classifies a specific population into homogeneous subgroups based on some key body dimensions. Standard sizing systems range linearly from very small to very large. ...

In 20 patients undergoing hybrid total hip arthroplasty, the reproducibility and accuracy of templating using digital radiographs were assessed. Digital images were manipulated using either a ten-pence coin as a marker to scale for magnification, or two digital-line methods using computer software. On-screen images were templated with standard acetate templates and compared with templating perf...

Gravitational lensing by large-scale structure induces weak coherent alignments in the shapes of background galaxies. Here we present evidence for the detection of this ‘cosmic shear’ at the 3.4σ significance level with the William Herschel Telescope. Analysis and removal of notable systematic effects, such as shear induced by telescope optics and smearing by tracking and seeing, are conducted ...

This paper presents an analysis of the results of an empirical study conducted to examine the relationship between the estimated and actual sizes of small real-client projects. Estimates of software size are collected at two different points of the software development life cycle – one immediately before rebaselining the project mid-stream and the other immediately after rebaselining. It is fou...

To help identify the strengths of proposed software measurement methods, this paper proposes an analytical approach based on metrology concepts documented in the ISO International Vocabulary of Basic and General Terms in Metrology. This approach is illustrated with a case study using one specific functional size measurement method recognized as an ISO standard: COSMIC-FFP (ISO 19761). The case ...
