An innovative traceability system for material flows in industrial plants
No full textPurpose
The article is centred on the analysis of internal flow traceability of products within indoor environments. The purpose of the paper is to provide an innovative automatic solution for the traceability of everything that moves within industrial plants, in order to simplify and improve the process of logistics flow traceability and optimisation.
Design/Methodology/Approach
In order to analyse the traceability of material flows within indoor environments, the authors have developed an experimental research consisting in a prototype development based on a Radio Frequency IDentification (RFID) system using Ultra Wind Band (UWB) technology. The authors have realised several tests (static and dynamic) that trace the positions (static) and map the movements (dynamic) of products within indoor environments in continuous and in real-time. .
Originality/Value
The paper presents an innovative automatic traceability system for the optimal determination and measurement of the positions and paths travelled by products within industrial plants. The traceability system described in the paper is able to quickly provide the measurement (i.e. positions and paths) with a high level of accuracy and precision in a continuous manner and not only collecting several gates crossing
The Use of Radio Frequency Identification Technology in Packaging Systems: Experimental Research on Traceability
Full text linkTraditionally, the traceability system is performed through the asynchronous fulfilment of checkpoints (i.e. doorways) by materials. In such cases, the tracking is manual, executed by operators that manually trace the path. Often, companies are not aware of the inefficiencies because of these traceability systems such as low precision and accuracy in measurements (i.e. no information between doorways), more time spent by operators and costs (due to the full effort of operators who have to search for the good positions and movements). In order to overcome these limitations, automatic identification procedures have been introduced in many service industries, purchasing and distribution logistics, manufacturing companies and material flow systems. Automatic identification procedures can also be applied to the packaging of products, instead of to each item contained in the package. Sometimes, products are very expensive, and packages contain important and critical goods (e.g. dangerous or explosive materials); thus, the tracking of goods – and packages in particular – is a critical function.
In order to analyse the traceability of the packaging system, the authors have developed an innovative system based on Radio Frequency IDentification-Ultra Wide Band (RFID-UWB) technology. A prototype of this system has been realized and used for an experimental research that has consisted of several tests (static and dynamic), tracing the position (static) and movements (dynamic) of products and in particular packages in indoor environments, in continuous and in real time.

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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
A new paradigm for packaging design in web based commerce
Full text linkE-commerce is one of the most important
features to have emerged from the presence of the
Internet. It allows people to exchange goods with low
time or distance barriers. E-commerce creates new
opportunities; meanwhile, it also presents new
challenges in terms of supplying chain management,
particularly regarding the packaging system.
Packaging functions have had to develop along with
the new requirements enforced by e-commerce (i.e.,
increased amounts of packaging materials for each
product, an increased need to protect items, end-life
management, environmental sustainability, etc.).
In this paper, the authors propose an original reference
framework for the design of a product packaging system
that can be applied to e-operations. According to the
framework, the authors have developed a mathematical
model for evaluating the cost that a company has to
sustain when partaking in e-commerce business. In
conclusion, the paper discusses the application of both
the framework and the mathematical model to a case
study in order to develop an innovative packaging
solution for e-commerce
