Abstract

Preserving the vast amount of digitally published data is of paramount importance to maintaining the intellectual heritage. In order that resources can be deposited, managed and retrieved, it will be necessary to accurately describe what has been preserved and how it has been preserved. This paper looks at the problems of producing accurate and effective metadata that describe preserved resources without incurring a prohibitive cost overhead. It investigates the extent to which existing metadata standards may be able to address this problem and specifically analyses whether ONIX metadata could be integrated into the preservation process.

Abstract

Purpose

The purpose of this research is to design a robust high-performance nonlinear multi-input multi-output heating, ventilation and air conditioning (HVAC) system controller for temperature and relative humidity regulation. Buildings are complex systems which are subjected to many unknown disturbances. Further complicating the control problem is the fact that, in practice, buildings and their systems have static nonlinearities such as power saturation that make stability difficult to guarantee. Therefore, in order to overcome these issues, a control system must be designed to be robust (performance insensitive) against uncertainties, static nonlinearities and effectively respond to unknown heat load and moisture disturbances.

Design/methodology/approach

A state of the art nonlinear inverse dynamics (NID) technique is combined with a genetic algorithm (GA) optimisation scheme in order to improve robustness against uncertainty in the system's modelling assumptions. The parameter uncertainty problem is addressed by optimising the control system parameters over a specified range of uncertainty. The NID control structure provides further robustness with effective disturbance handling and a stability criteria that holds in the presence of actuator saturation.

Findings

The proposed method delivers significantly more energy efficient performance whilst achieving improved thermal comfort when compared with a current industry standard HVAC controller design such as proportional-integral-derivative. The expected excellent response to disturbances is also demonstrated.

Research limitations/implications

This method can easily be extended to account for other parameters with a specified uncertainty range.

Practical implications

This research presents a method of optimised NID controller design which can be easily implemented in real HVAC controllers of building energy management systems with a high degree of confidence to provide high levels of thermal comfort whilst significantly reducing energy usage.

Originality/value

A novel HVAC optimised NID control strategy using the robust inverse dynamics estimation feedback control topology with GA optimisation for improved robustness and tuning over a range of parameter uncertainty is described, designed and its performance benefits shown through simulation studies.

Abstract

FINANCIAL fears are only less cruel than those of war, and lead men into extravagances which they would repudiate indignantly in their cooler moments. If the doings of the Economy Committee at Manchester in relation to children's libraries, as described in the article by Mr. Lamb in our last issue, are true, we have in them an example of a kind of retrenchment at the expense of the young which we hope is without parallel and will have no imitators. Some reduc‐tion of estimates we hear of from this or that place, but in few has the stupid policy which urges that if we spend nothing we shall all become rich been carried into full effect. Libraries always have suffered in times of crisis, whatever they are; we accept that, though doubtfully; but we do know that the people need libraries.

This paper contrasts the determinants of online disclosures about self and others in social media.

Abstract

Purpose

This paper contrasts the determinants of online disclosures about self and others in social media.

Design/methodology/approach

Data from 216 respondents were collected through an online survey. The formal research model was tested with covariance based structural equation modeling.

Findings

The determinants of online disclosures vary whether the subject is self or others. Social networking site (SNS) users who self-disclose are also more likely to share information about others. Furthermore, there are significant gender effects in the influences of disclosure as revealed by multi-group SEM.

Research limitations/implications

Future research models should incorporate the construct of disclosure about others and examine the intertwining of different types of disclosure on SNS. Future work should include behavioral measures, as this study relied on self-report measures.

Practical implications

The current understanding of information sharing does not accommodate different forms of disclosure. Employers or systems administrators concerned about data sharing may need to tailor interventions to the subject of the disclosure. Furthermore, the significant gender differences in determinants of disclosure suggest that this should be considered in practical applications.

Originality/value

Disclosure about others has not been examined in prior work. This study contributes by offering empirical data on the contrasting determinants of disclosure as well as gender differences. It improves the understanding of online information sharing, a topic of particular relevance in today's information oriented society.

Abstract

Not many weeks back, according to newspaper reports, three members of the library staff of the School of Slavonic and East European Studies in London were dismissed. All had refused to carry out issue desk duty. All, according to the newspaper account, were members of ASTMS. None, according to the Library Association yearbook, was a member of the appropriate professional organisation for librarians in Great Britain.
