Reducing the Intrusiveness of Energy and Water End-use Disaggregation via Social Media and Users Interactions
No full textWater end-use disaggregation from smart-metered water consumption data is key to design water demand management strategies. Yet, despite large investments for smart metering networks, few water utilities are actually exploiting the potential of end-use-based consumer profiling. This is mostly due to the intrusiveness of existing disaggregation algorithms, which require intensive and time consuming human interaction for extracting appliance-specific information and estimating the end-use patterns. We propose to explore the potential for social media in facilitating the interactions between water utilities and water users in order to collect consumption diaries. The evaluation of the value of this user-generated information is performed by using the collected diaries as input for a disaggregation algorithm, which is shown to attain acceptable performance in reproducing the end-use patterns
Model driven data synchronization for mobile applications
Full text linkLAUREA MAGISTRALELa pervasività delle applicazioni mobili nell’industria dell’ingegneria del
software ha causato l’introduzione di un notevole insieme di problematiche,
tra cui spiccano quelle relative al deployment, a causa della moltitudine di
piattaforme e dispositivi da servire. L’approccio Model Driver Engineering,
fondato su una metodologia di design indipendente dalla piattaforma in grado
di affrontare tali criticità, richiede modelli avanzati e sofisticate tecniche di
generazione di codice. In questo studio, incentrato sulla modellazione, miriamo
ad introdurre nuovi pattern di design capaci di conciliare concetti di User Experience (UX) e logica di business, ovvero pattern di sincronizzazione dati
associati all’interazione. La natura trasversale di questi artefatti ci permette
di integrarli nei modelli di design front-end, potenziandone la forza espressiva e introducendo continuità con la logica di back-end. Dal momento che
la definizione dei pattern esige un’approfondita esaminazione preliminare,
la nostra ricerca è avviata dall’analisi di alcune applicazioni complesse già
presenti sul mercato, atta alla deduzione delle dinamiche scatenanti degli
eventi di sincronizzazione dati, con particolare attenzione alle implicazioni
sull’interazione dell’utente. Di seguito, presentiamo alcuni pattern centrati
sull’interazione, ottenuti dalla valutazione dei risultati dell’indagine. Successivamente, il filo conduttore del lavoro devia verso la sincronizzazione dati
in applicazioni mobili, introducendone gli aspetti fondamentali e le diverse
specializzazioni associate ai rispettivi criteri di adozione. Poiché le complessità specifiche di tale dominio hanno già ispirato la concezione di pattern di
sincronizzazione dati per applicazioni mobili, la nostra ambizione consiste nel
combinare questi pattern con quelli ottenuti dalla già citata esaminazione
sull’interazione dell’utente. Gli artefatti risultanti da questo stadio sono infine mostrati nell’integrazione in uno scenario reale di modellazione software,
accompagnato da spiegazioni esaustive su scelte di progettazione, impatto
sulla potenza espressiva del modello e problematiche incontrate o potenziali.The pervasiveness of mobile applications in the software engineering industry has been introducing a remarkable set of problems, among which the
deployment-related ones stand out, due to the multitude of platforms and
devices to serve. The Model Driven Engineering (MDE) approach, proposing
a platform independent design methodology taking on these difficulties, requires enhanced models and sophisticated code generation techniques. In this
model-centered study, we aim at introducing new design patterns joining the
concepts of User Experience (UX) and software business logic: data synchronization patterns associated to interaction. The transverse nature of these
artifacts allows us to feature them in front-end designs models, augmenting
their expressive power and providing continuity with the back-end logic. As
the definition of patterns requires a profound preliminary examination, our
research starts by analyzing some complex real-world applications to infer the
triggering dynamics of data synchronization, underscoring their implications
on user interaction. Eventually, we present some interaction-centered patterns
derived from the results of this inquiry. Subsequently, the main thread of
our work deviates to data synchronization in mobile applications, introducing
its core aspects, different specializations and their adoption criteria. Since
the domain-specific complexities have already inspired the conception of data
synchronization patterns for mobile applications in literature, our objective is
to combine these patterns with the outcomes of the aforementioned examination over user interaction. The resulting artifacts of this stage are finally
shown at work into a real-world application modeling scenario, followed by
a detailed explanation of design choices, impact on expressive power of the
model and encountered or potential issues
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
