1. The Data Librarian: laboratories today—the need for the Librarian

This first part of ‘The Data Librarian’ describes the current situation in analytical laboratories and the need for the Data Librarian. The second part of the paper (Liscouski, J., 1997, Journal of Automatic Chemistry, 19, 199-204) will examine the features of the Data Librarian.     

Evaluating the scope for energy-efficiency improvements in the public sector: Benchmarking NHSScotland's smaller health buildings

The National Health Service in Scotland (NHSScotland) has, in recent years, done much to reduce energy consumption in its major healthcare buildings (hospitals). On average, a reduction of 2% per year has been achieved since 2000, based on hospital buildings. However, there had been little or no attention paid to smaller premises such as health centres, clinics, dentists, etc. Such smaller healthcare buildings in Scotland constitute 29% of the total treated floor area of all NHSScotland buildings and, therefore, may contribute a similar percentage of carbon and other emissions to the environment. By concentrating on a sample of local health centres in Scotland, this paper outlines the creation of an energy benchmark target, which is part of a wider research project to investigate the environmental impacts of small healthcare buildings in Scotland and the scope for improvements. It was found that energy consumption varied widely between different centres but this variation could not be linked to building style, floor area or volume. Overall, it was found that a benchmark of 0.2 GJ/m³ would be challenging, but realistic.

Privileging the “Objective”: Understanding the State’s Role in Shaping Housing Aspirations

This paper is to be read as one half of a twofold analysis of recent qualitative research on the housing aspirations of the people of Scotland, focusing specifically on the dimension of housing tenure. Moving beyond individual subjective preferences (i.e. what people “consciously” want or desire in relation to housing), this paper draws influence from David Harvey’s historical materialist approach to illustrate the importance of understanding the dialectical relation between objective reality and subjective preferences. We argue that it is by examining the broad homologies between the qualitative data on one hand, and the corresponding epochs of capital accumulation on the other, that important power structures can be made visible, and changes in housing aspirations over time better understood.     

Sensitiveness of Porous Silicon‐Based Nano‐Energetic Films

Nanoporous silicon (pSi) films on a silicon wafer were loaded with sodium perchlorate and perfluoropolyether (PFPE) oxidizing agents. Sensitiveness to impact, friction and electrostatic discharge (ESD) of the resulting energetic thin films were investigated. It was observed that pSi loaded with perchlorate was sensitive at the lowest limit of detection for the available equipment (<4.9 J impact energy, <5 N friction force, and <45 mJ ESD spark energy). When loaded with PFPE the material was very sensitive to impact (<4.9 J), moderately sensitive to ESD (between 45 and 100 mJ) and insensitive to friction (>360 N). pSi loaded with either perchlorate or PFPE displayed behavior during sensitiveness testing similar to other primary explosive materials.     

Total projection to latent structures for process monitoring

Partial least squares or projection to latent structures (PLS) has been used in multivariate statistical process monitoring similar to principal component analysis. Standard PLS often requires many components or latent variables (LVs), which contain variations orthogonal to Y and useless for predicting Y . Further, the X ‐residual of PLS usually has quite large variations, thus is not proper to monitor with the Q‐statistic. To reduce false alarm and missing alarm rates of faults related to Y , a total projection to latent structures (T‐PLS) algorithm is proposed in this article. The new structure divides the X ‐space into four parts instead of two parts in standard PLS. The properties of T‐PLS are studied in detail, including its relationship to the orthogonal PLS. Further study shows the space decomposition on X ‐space induced by T‐PLS. Fault detection policy is developed based on the T‐PLS. Case studies on two simulation examples show the effectiveness of the T‐PLS based fault detection methods. © 2009 American Institute of Chemical Engineers AIChE J, 2010     

Temperature Effects on a Non-Volatile Memory Device with Ferroelectric Capacitor

The temperature effects on a ferroelectric non-volatile memory latch were measured. The device is based on a design from Radiant Technologies Inc. utilizing a discrete ferroelectric capacitor. The effects measured include functionality, I-V characteristics and retention. The range of temperatures for which the device was tested is –107°F to +302°F. The results are compared with measurements made at room temperature for the device. Retention measurements of the device at elevated temperatures allow predictions of retention performance under normal operating conditions. Potential applications of this device in harsh environments which include aerospace, industrial and automotive are presented.
