The extended minimal geometric deformation of SU(NN) dark glueball condensates

The extended minimal geometric deformation (EMGD) procedure, in the holographic membrane paradigm, is employed to model stellar distributions that arise upon self-interacting scalar glueball dark matter condensation. Such scalar glueballs are SU($N$) Yang-Mills hidden sectors beyond the Standard Model. Then, corrections to the gravitational wave radiation, emitted by SU($N$) EMGD dark glueball stars mergers, are derived, and their respective spectra are studied in the EMGD framework, due to a phenomenological brane tension with finite value. The bulk Weyl fluid that drives the EMGD is then proposed to be experimentally detected by enhanced windows at the eLISA and LIGO.Comment: 9 pages, 7 figure

Extended quantum portrait of MGD black holes and information entropy

The extended minimal geometric deformation (EMGD) is employed on the fluid membrane paradigm, to describe compact stellar objects as Bose--Einstein condensates (BEC) consisting of gravitons. The black hole quantum portrait, besides deriving a preciser phenomenological bound for the fluid brane tension, is then scrutinized from the point of view of the configurational entropy. It yields a range for the critical density of the EMGD BEC, whose configurational entropy has global minima suggesting the configurational stability of the EMGD BEC.Comment: 9 pages, 7 figures, matches the published versio

From the armed struggle against the dictatorship to the socialist revolution: the narrative restraints to lethal violence among radical left organisations in Portugal

This article presents a historical case study of three armed organisations that operated in Portugal before and after the April Revolution of 1974. This event put an end to Estado Novo’s authoritarian regime, starting a period of transition to democracy. The armed organisations operating during Estado Novo sought, essentially, to combat the dictatorship and the Colonial War. These organisations channelled their actions towards the destruction of the regime’s repressive and colonial apparatus, but refused to use lethal violence. During the transition to democracy, disillusionment caused by the negative outcome of the revolutionary process and the end of the utopia of the socialist revolution led some sectors of the radical left to return to armed struggle. This time, such actors targeted both property and human beings but were highly selective in their targeting. We analyse the narratives of restraint of former militants from across these groups, and consider how they were shaped by the evolving socio-political context. In the case of the pre-revolution organisations, we found two collectively accepted narratives inscribed in their genesis: lethal violence as counterproductive and lethal violence as philosophically and ideologically problematic. In the case of the post-revolution organisation we found one restraint narrative shared by the collective: indiscriminate lethal violence is counterproductive. Some militants also developed a restraint narrative that centred on disappointment with the organisation for its perceived operational failures. This study is based on a narrative analysis of data dispersed across personal and public archives, writings, and memoirs of individuals directly and indirectly involved in the armed struggle, with data collected through interviews with former politically violent militants.info:eu-repo/semantics/publishedVersio

Simulation and Control of a Cyber-Physical System under IEC 61499 Standard

IEC 61499 standard provides an architecture for control systems using function blocks (FB), languages, and semantics. These devices can be interconnected and communicate with each other. Each device contains several resources and algorithms with a communication FB at the end, which can be created, configured, and deleted without affecting other resources. Physical element can be represented by a FB that encapsulates the functionality (data/events, process, return data/events) in a single module that can be reused and combined. This work presents a simplified implementation of a modular control system using a low-cost device. In the prototyping of the application, we use 4diac to control, model and validate the implementation of the system on a programmable logic controller. It is proved that this approach can be used to model and simulate a cyber-physical system as a single element or in a networked combination. The control models provide a reusable FB design.We acknowledge the financial support of CIDEM, R&D unit funded by FCT – Portuguese Foundation for the Development of Science and Technology, Ministry of Science, Technology and Higher Education, under the Project UID/EMS/0615/2019, and it was supported by FCT, through INEGI and LAETA, under project UIDB/50022/2020.info:eu-repo/semantics/publishedVersio

Seismic vulnerability assessment of the old city centre of Seixal, Portugal

The seismic vulnerability assessment of old traditional masonry building stocks, in a seismic risk mitigation perspective, is truly essential not only for buildings with recognized historical and patrimonial value, but also, in relation to regular buildings. In this sense, this paper approaches the issue of the seismic vulnerability assessment of masonry buildings through the application of a simplified methodology to building stock of the old city centre of Seixal, Portugal. This methodology is based on a vulnerability index, suitable in the evaluation of damage and in the creation of large scale loss scenarios (economical and human). Over 500 buildings were evaluated in accordance with the referred methodology and the results obtained were then integrated into a Geographical Information System tool. The integration of this kind of vulnerability and loss results into a GIS tool allows that city councils or regional authorities make their decisions based on a global view of the site under analysis, which led to more accurate and faster decisions either in terms of risk mitigation strategies or rehabilitation plans. This tool can also assumes great importance in the construction of safety and rescue plans

Vulnerability assessment of urban building stock: a hierarchic approach

In the last decades the evaluation of the seismic risk are of rising concern, considered essential in the activity and definition of strategy planning and urban management. The evaluation of the seismic vulnerability of the existent building stock in the perspective of the seismic risk mitigation should not be placed only in relation to the isolated buildings of relevant historical and cultural importance, but also, in relation to the agglomerate of buildings in urban centres. The chronological construction process frequently results in characteristic heterogeneity of masonry and wall connection quality. In addition, buildings do not constitute independent units given that they share the mid-walls with adjacent buildings and the façade walls are aligned. This way, as post-seismic observations proved, buildings do not have an independent structural behaviour, but they interact amongst themselves, mainly for horizontal actions and so the structural performance should be studied at the level of the aggregate and not only for each isolated building. In most cases, for masonry structures there is no need for sophisticated dynamic analyses for seismic resistance verification or vulnerability assessment. This is even more relevant when an assessment at the level of a city centre is pursued. In this work, the results of evaluation of the vulnerability will be presented in accordance to three proposed methodologies based on a vulnerability index that consequently allows the evaluation of damage and creation of loss scenarios (economical and human) not only at the level of the building and its façade walls but also at the level of the aggregates. It will be discussed and evaluated the application of the referred methodologies and its integration in an SIG platform

Afilamento e forma do tronco de árvores de Eucalyptus grandis e Eucalyptus saligna e suas variações com a adubação.

Este trabalho analisa possíveis alterações no afilamento médio e fator de forma de árvores de Eucalyptus saligna e Eucalyptus grandis pelo efeito de aplicação de fertilizantes no momento de plantio e parcelada durante a rotação. Os experimentos de adubação, com estas espécies foram implantados na região dos cerrados, nos municípios de Brotas e Altinópolis, Estado de São Paulo. Os tratamentos foram selecionados devido à elevada resposta à adubação obtida ao final da rotação. Os resultados obtidos para afilamento médio e fator de forma, de parcelas e árvores adubadas e não adubadas, possibilitaram as seguintes conclusões: a) O afilamento médio das parcelas diminuiu do quarto para o sexto ano e posteriormente aumentou para o oitavo ano. Aparentemente, estas variações deveram-se a uma redução na taxa de crescimento em altura e um aumento na taxa de crescimento em diâmetro, durante o mesmo período. b) A adubação melhorou levemente a forma das árvores do Eucalyptus grandis, e este efeito está indiretamente relacionado com as diferentes quantidades de fertilizantes devido ao seu efeito no crescimento em altura das árvores. c) As variações no afilamento médio das árvores podem ser atribuídas às alterações nos padrões de crescimento em altura e diâmetro. Variáveis diferentes que alteram a conicidade das árvores, devem ser primeiramente analisadas em relação à sua influência no crescimento em altura e diâmetro, antes de serem consideradas como fatores isolados. d) Nenhuma alteração foi verificada, na relação entre o diâmetro à altura do peito e na metade da altura da árvore, que pudesse ser atribuída às doses ou métodos de aplicação de fertilizantes. e) Não foi possível obter-se uma regressão precisa para estimar fatores de forma baseada nas variáveis estudadas neste trabalho

Conflict-Aware Active Automata Learning

Active automata learning algorithms cannot easily handle conflict in the observation data (different outputs observed for the same inputs). This inherent inability to recover after a conflict impairs their effective applicability in scenarios where noise is present or the system under learning is mutating. We propose the Conflict-Aware Active Automata Learning (C AL) framework to enable handling conflicting information during the learning process. The core idea is to consider the so-called observation tree as a first-class citizen in the learning process. Though this idea is explored in recent work, we take it to its full effect by enabling its use with any existing learner and minimizing the number of tests performed on the system under learning, specially in the face of conflicts. We evaluate C AL in a large set of benchmarks, covering over 30 different realistic targets, and over 18,000 different scenarios. The results of the evaluation show that C AL is a suitable alternative framework for closed-box learning that can better handle noise and mutations
