Abstract. Sulfuric acid and dimethylamine vapours in the atmosphere can form molecular clusters, which participate new particle formation events. In this work, we have produced, measured, identified clusters of sulfuric using an electrospray ionizer coupled with a planar-differential mobility analyser, connected to atmospheric pressure interface time-of-flight mass spectrometer (ESI–DMA–APi-TOF...

Abstract Sending microwaves through bauxite ore allows almost continuous measurement of moisture content during offload by conveyor belt from a ship. Data and results microwave analyser were brought to European Study Group with Industry at the University Limerick, over-arching question whether are accurate enough. The equipment uses linear regression against phase shifts signal attenuation infe...

The Sugar Research Institute (SRI) in Australia provided the SMRI with a Sucrose Analyser for evaluation. Although the Sucrose Analyser is designed for online measurement of sucrose concentrations, this application describes the direct measurement of sucrose in factory streams in a laboratory environment. The Sucrose Analyser provides a quick and cost effective way of estimating the sucrose con...

Developments in modern neutron spectroscopy have led to typical sample sizes decreasing from few cm to several mm in diameter samples. We demonstrate how small samples together with the right choice of analyser and detector components makes distance collimation an important concept in crystal analyser spectrometers. We further show that this opens new possibilities where neutrons with different...

The increasing demand in automatic code transformation tools – which can preserve the layout, and can handle the whole macro syntax – led us to develop our scanner and parser tool. ParsErl is a generic syntactic analyser for Erlang. The scanner and the parser are generated from an XML definition of the grammar. The result of the scanning process is a graph, which can be optimised or balanced fo...

OBJECTIVES To evaluate the performance of automated leucocyte (white blood cell; WBC) counting by comparison with manual counting. METHODS The number of WBC was determined in heparinized synovial fluid samples by the use of (i) a standard urine cytometer (Kova) and a microscope (reference method) and (ii) a haematology analyser (Sysmex XE-2100; WBC/BASO and DIFF channels). Imprecision within ...

Machine learning and knowledge acquisition from experts have distinct knowledge acquisition capabilities that appear to be complementary. This study demonstrates that the integration of these approaches can both improve the accuracy of the knowledge base that is developed and reduce the time taken to develop it. In addition, users expected the expert systems created through the integrated appro...

Small machine shops typically do not have the resources to develop custom simulations of their operations or data translators to import their data from other manufacturing software applications. This paper presents an overview of an information model currently under development at the National Institute of Standards and Technology (NIST) to address this problem. The model provides neutral data ...
