    "Utilização de padrões de desenho de software no desenvolvimento de Sistemas de Informação Geográfica" - O caso da Região Demarcada do Douro
    ( 2011) Nelson Bilber Rodrigues ; Lino Oliveira ; Lígia Silva ; António Coelho ; 4290 ; 4777 ; 3574 ; 3132
    A Região Demarcada do Douro (RDD) possui características únicas a nível mundial e requer um sistema de classificação das parcelas com vinha que assegure os níveis de elevada qualidade dos vinhos do Douro e Porto. Com base neste pressuposto, foi desenvolvido um Sistema de Informação Geográfica para a gestão e classificação das parcelas com vinha da RDD. O sistema foi desenhado utilizando padrões de desenho de software com o objectivo de tornar a sua evolução sustentável, respondendo aos novos requisitos e preservando o legado inicial. Neste artigo é apresentada uma metodologia que permite a utilização de Rich Internet Application (RIA) sobre as aplicações Web tradicionais, proporcionando interfaces gráficas (GUI) mais ricas, dinâmicas e interactivas, tornando as aplicações mais atractivas para o utilizador. É apresentado ainda um padrão de desenho de software, derivado do Model -View- Controller (MVC) designado por Model - View - LogicGateway (MVLG). É um padrão de arquitectura de softw

    Automatic characterisation of Dansgaard-Oeschger events in palaeoclimate ice records
    ( 2023) Susana Alexandra Barbosa ; Maria Eduarda Silva ; Nuno Dias ; Rousseau,D ; 5567 ; 6363 ; 8707
    <p align="justify">Greenland ice core records display abrupt transitions, designated as Dansgaard-Oeschger (DO) events, characterised by episodes of rapid warming (typically decades) followed by a slower cooling. The identification of abrupt transitions is hindered by the typical low resolution and small size of paleoclimate records, and their significant temporal variability. Furthermore, the amplitude and duration of the DO events varies substantially along the last glacial period, which further hinders the objective identification of abrupt transitions from ice core records Automatic, purely data-driven methods, have the potential to foster the identification of abrupt transitions in palaeoclimate time series in an objective way, complementing the traditional identification of transitions by visual inspection of the time series.</p> <p align="justify">In this study we apply an algorithmic time series method, the Matrix Profile approach, to the analysis of the NGRIP Greenland ice core record, focusing on:</p> <p align="justify">- the ability of the method to retrieve in an automatic way abrupt transitions, by comparing the anomalies identified by the matrix profile method with the expert-based identification of DO events;</p> <p align="justify">- the characterisation of DO events, by classifying DO events in terms of shape and identifying events with similar warming/cooling temporal pattern</p> <p align="justify">The results for the NGRIP time series show that the matrix profile approach struggles to retrieve all the abrupt transitions that are identified by experts as DO events, the main limitation arising from the diversity in length of DO events and the method’s dependence on fixed-size sub-sequences within the time series. However, the matrix profile method is able to characterise the similarity of shape patterns between DO events in an objective and consistent way.</p>

    New language technologies are coming, thanks to the huge and competing private investment fuelling rapid progress; we can either understand and foresee their effects, or be taken by surprise and spend our time trying to catch up. This report scketches out some transformative new technologies that are likely to fundamentally change our use of language. Some of these may feel unrealistically futuristic or far-fetched, but a central purpose of this report - and the wider LITHME network - is to illustrate that these are mostly just the logical development and maturation of technologies currently in prototype. But will everyone benefit from all these shiny new gadgets? Throughout this report we emphasise a range of groups who will be disadvantaged and issues of inequality. Important issues of security and privacy will accompany new language technologies. A further caution is to re-emphasise the current limitations of AI. Looking ahead, we see many intriguing opportunities and new capabilities, but a range of other uncertainties and inequalities. New devices will enable new ways to talk, to translate, to remember, and to learn. But advances in technology will reproduce existing inequalities among those who cannot afford these devices, among the world’s smaller languages, and especially for sign language. Debates over privacy and security will flare and crackle with every new immersive gadget. We will move together into this curious new world with a mix of excitement and apprehension - reacting, debating, sharing and disagreeing as we always do. Plug in, as the human-machine era dawns.

    Correction to: Collaborative immersive authoring tool for real-time creation of multisensory VR experiences (Multimedia Tools and Applications, (2019), 10.1007/s11042-019-7309-x)
    ( 2020) Hugo Rafael Mendes ; Miguel Correia Melo ; José Luís Martins ; Maximino Bessa ; 5095 ; 7622 ; 5408 ; 6516
    In the original publication, Figs. 1 and 2 were interchange and the citation of Fig. 1 in the third paragraph of section 2.2 Authoring tools for multisensory VR experiences should be removed. The citation of Fig. 2 in section 3.1 System architecture should be changed to Fig. 1 and the citation of Fig. 1 in the same section should be change to Fig. 2. Also, the acknowledgement is missing in the original publication. The corrected figures and acknowledgement are presented in this erratum. © 2020, Springer Science Business Media, LLC, part of Springer Nature.
