Blind competition on the numerical simulation of slabs reinforced with conventi...
Barros, Joaquim A. O.; Sanz, Beatriz; Filho, Marcílio; Kabele, Petr; Yu, Rena C.; Meschke, Günther; Planas, Jaime; Cunha, Vitor; Neu, Gerrit E.This paper describes the 3rd Blind Simulation Competition (BSC) organized by the fib WP 2.4.1 which aims to assess the predictive performance of models based on the finite element method (FEM) for analysis and design of fiber reinforced concrete (FRC) structures submitted to loading and support conditions that promote punching failure mode. Fiber reinforcement is used in an attempt to eliminate conventional pun...
A multidisciplinary engineering-based approach for tunnelling strengthening wit...
Barros, Joaquim A. O.; Costelha, Hugo; Bento, David; Brites, Nelson; Luís, Rui; Patrício, Hugo; Cunha, Vitor; Bento, Luís; Miranda, Tiago; Coelho, PauloThis paper describes the relevant research activities that are being carried out on the development of a novel shotcrete technology capable of applying, autonomously and in real time, fibre reinforced shotcrete (FRS) with tailored properties regarding the optimum structural strengthening of railway tunnels (RT). This technique allows to apply fibre reinforced concrete (FRC) of strain softening (SSFRC) and strai...
Importância de interferentes medicamentosos no Acidente Vascular Cerebral (AVC)...
Silva, Ângela; Cunha, VitorEnquadramento: O diagnóstico do Acidente Vascular Cerebral (AVC), consiste na realização de um exame de imagem cerebral [1]. Seguem-se estudos analíticos específicos que serão fundamentais no diagnóstico e tratamento adjacentes [2,10]. Tais como a realização de hemograma, bioquímica, estudo da coagulação, doseamento de anticoagulantes orais diretos (DOACs), doseamento de marcadores de necrose miocárdica, pesqui...
Moving Target Defense for the cloud/edge Telco environments
Escaleira, Pedro; Cunha, Vitor; Gomes, Diogo; Barraca, João P.; Aguiar, Rui L.The Internet of Things (IoT) paradigm has been one of the main contributors, in recent years, to the growth in the number of connected equipment. This fact has predominantly contributed to IoT being constrained by the 5th Generation Mobile Network (5G) progress and the promises this technology brings. However, this can be a double-edged sword. On the one hand, it will benefit from those progresses, but on the o...
Competición a ciegas de simulaciones numéricas del fallo a cortante de vigas de...
Barros, Joaquim A. O.; Sanz, Beatriz; Kabele, Petr; Yu, Rena C.; Meschke, Günther; Planas, Jaime; Cunha, Vitor; Caggiano, Antonio; Ozyurt, NilüferLa investigación experimental ha demostrado el extraordinario potencial de la adición de fibras cortas a los materiales cementiceos, ya que mejoran significativamente el comportamiento de estructuras de hormigón en los estados límite de servicio y último. Para la simulación del comportamiento no lineal del material en estructuras de hormigón reforzado con fibras se utilizan programas informáticos basados en el ...
Earth-based Render of Tabique Walls–An Experimental Work Contribution
Pinto, Jorge; Cunha, Sandra; Soares, Nuno; Soares, Edgar; Cunha, Vitor; Ferreira, Débora; Sá, Ana BrigaA research work focused on studying earth render for tabique application purposes is presented. Initially, a brief description of the tabique building technique is provided. The relevance of the application of this traditional building technique is also highlighted. Different compositions of earth render are experimentally analyzed and the respective performance is evaluated. Flexural and compressive strengths,...
Policy-driven vCPE through dynamic network service function chaining
Cunha, Vitor; Cardoso, Igor Duarte; Barraca, João Paulo; Aguiar, Rui Luís AndradeVirtual CPEs address the low agility, slow time-to-market and high costs (of development, deployment and support) that are inheritable to traditional CPEs. They take advantage of the economics of Cloud Computing and the ability to run Virtual Network Functions in a general computing platform to build richer services, with faster development and deployment times, all whilst reducing costs. When coupled together ...

Pinto, Jorge; Cunha, Vitor; Teixeira, Tiago; Ferreira, Débora; Briga-Sá, Ana; Varum, HumbertoA pedra de xisto é um material natural e local comummente utilizado nas construções tradicionais do Concelho de Peso da Régua. Esta zona do Nordeste Português está inserida na região do Douro que é classificada como Património Mundial pela UNESCO. Os muros de divisão de terrenos, de suporte de terras e os edifícios de construção tradicional são os tipos de construção em que a pedra de xisto é o material dominan...
Schist buildings in Peso da Régua county
Pinto, Jorge; Cunha, Vitor; Teixeira, Tiago; Ferreira, Débora; Briga-Sá, Ana; Varum, HumbertoSchist stone is a traditional building material applied in the Peso da Régua County. This County is located in the Northeast part of Portugal related to the Douro region which is UNESCO World Heritage. Dwellings, earth retaining walls and fencings are the most common constructions built with this type of material. They are vernacular constructions which are very well integrated in the local landscape and its ma...
