No full textEnvironmental protection in research laboratories presents specific managerial problems strictly related to the fact that most of actual environmental managerial requirements are based on regulations tailored to relatively simple and continuous processes in manufacturing and service entities. In research labs the variety of substances used and the likelihood of creating new substances are generally higher than in industrial processes, while the quantity of substances is always significantly lower. Furthermore specific managerial criteria are necessary in order to take into account on one hand the variability of operations, on the other hand the impossibility to define in detail each operation. A practical criterion usable as decision making support for the organization of laboratory activities is presented in this work. The use of this criterion is aimed at obtaining the necessary authorizations from the competent authorities by ensuring, implicitly and preventively, the compliance with the regulatory threshold limits referred to the emissions in atmosphere. The first application of the methodology at University of Udine has permitted to derive some practical considerations in terms of environmental management that can be applied also in non academic research fields and in particular in small labs related to the process industry.

No full textParameter identifiability through information theory
Full text linkIn this paper, we address the problem of assessing the identifiability of model parameters in a mechanical system, i.e., whether unknown parameters can be estimated given a set of measurements collected through sensor networks. Practical identifiability can arise due to either a lack of sensitivity or a joint effect of the parameters on the measurements. Information theory can be used to detect the sources of non-identifiability, with the purpose of establishing an efficient sensor network design. Mutual Information between the parameter and the measured outputs, and Conditional Mutual Information of each parameter couple, conditioned on the measurements, are considered. Adoption of these indices is overviewed for practically assessing the identifiability of the mechanical properties of a non-linear structural model
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
