Seismic vulnerability assessment of clustered historical centers: fragility curves based on local collapse mechanisms analyses

open5noProtection and preservation of minor historical centres against earthquakes effects are not trivial tasks, particularly in the cases, quite common, of complex aggregate buildings. The paper aims at evaluating the seismic vulnerability of historical clustered buildings on a urban scale, through the analysis of local collapse mechanisms, carried out with a parametric approach. This procedure is applied to four historical centres of L’Aquila province struck by the 2009 earthquake. The identification of the significant parameters is related to the definition of representative typologies within the city centres. Each typology is characterized by recurring features, mainly recognizable with a survey performed outside the buildings. After the identification of the relevant aspects, local mechanisms of collapse analyses are carried out, by varying the parameters between defined range of values, in order to take into account possible uncertainties in the data collection. A set of fragility curves for each identified typology is defined and the obtained results are compared to the damage data gathered in the post-earthquake phase for the buildings. This approach allows for possible extensions to buildings that may be included in the typology categories here defined.openTaffarel, S.; Caliman, M.; Valluzzi, M.R; da Porto, F.; Modena, C.Taffarel, Sabrina; Caliman, M.; Valluzzi, MARIA ROSA; DA PORTO, Francesca; Modena, Claudi

Programming with Quantum Mechanics

Quantum computing is an emerging paradigm that opens a new era for exponential computational speedup. Still, quantum computers have yet to be ready for commercial use. However, it is essential to train and qualify today the workforce that will develop quantum acceleration solutions to get the quantum advantage in the future. This tutorial gives a broad view of quantum computing, abstracting most of the mathematical formalism and proposing a hands-on with the quantum programming language Ket. The target audience is undergraduate and graduate students starting in quantum computing -- no prerequisites for following this tutorial

Beyond art, beyond humanities, beyond technology : a new creativity

The history of humanity shows how important it is the communication made in many ways by means of art! Communication and arts aer part of human life in a daily basis such that it is necessary to attempt to the importance of communication of its many channels and now more than ever-in real time. Not to mention the art that expresses in many ways the beauty, the odd and the reflections of realities. The academic community dedicated to the search of science of communication and arts can count with an international forum for the discussions about communication and arts research. it is the WCCA´2012 - World Congress in Communication and Arts organized by COPEC - Science and Education Research the Thema of WCCA´2012: "Beyond Art, Beyond Humanities, Beyond Technology: A New Creativity" has brought researchers and professionals of theses areas to participate at the conference showing their interesting scientific works

Engineering Education for the improvement of practice : preparing for labour market

Technical skill is associated with understanding and proficiency in a particular type of activity, especially those that are involved in methods, processes and procedures. As an example, one can take the training of the engineer, who - mostly - is focused moreover, on calculations, simulations and projects, characterizing it as an individual, above all, objective. Since the human ability can be understood as the ability of individuals to interact with others to form similar one that respects his fellow and nature this individual is aware of his/her own attitudes, opinions and beliefs about others. Realizing the existence of other attitudes, opinions and beliefs different from his/hers, the individual is able to understand them. By becoming aware of the need to combine their technical skills (to run its specific activity) with the human ability (to develop proactive human relationship), this professional develops the conceptual ability, which is directly associated with the coordination and integration of all attitudes and interests of the organization that owns or provides the service. In other words, not technical enough to be good, if not able to understand comprehensively the meaning of the activity that is being exerted, through these three interconnected skills. This aspect is the main one in terms of engineering formation for 21st Century Labor Market for engineers. The goal of this work is to show the engineering programs developed by COPEC with the objective to form engineers ready for the present labor market. The most successful program is the one based on Scientific Research Projects.(undefined

Evaluation of the Vertical Acuracy of Digital Elevation Models SRTM, ALOS WORLD 3D and ASTER GDEM: a case study in Vale dos Vinhedos, RS, Brazil

Este estudo tem como objetivo avaliar a acurácia vertical dos Modelos Digitais de Elevação (MDEs) SRTM v.3, ALOS World 3D e ASTER GDEM v.2 na região da denominação de origem Vale dos Vinhedos, RS. Para tanto, os dados desses MDEs, com resolução espacial de 30 m, foram comparados com os de um MDE fotogramétrico com resolução espacial de 5 m no terreno, por meio de análises de regressão e correlação linear, e de perfis topográficos derivados desses modelos. O Padrão de Exatidão Cartográfica dos Produtos Cartográficos Digitais (PEC-PCD) de cada MDE foi analisado, para identificar a escala máxima de seu uso em estudos morfométricos, nas escalas 1:25.000, 1:50.000 e 1:100.000, por meio de cálculos da Tolerância Vertical e do Erro Médio Quadrático (EMQ). Os MDEs SRTM v.3 e ASTER GDEM v.2 atenderam o PEC-PCD altimétrico classe A na escala 1:100.000. Diferentemente do MDE ALOS World 3D que se enquadrou na classe B para a escala de 1:100.000. Todos os modelos, na escala 1:50.000, enquadraram-se na classe D, enquanto na escala 1:25.000 não houve enquadramento. O MDE SRTM v.3 foi o que apresentou melhores resultados morfométricos e o maior coeficiente de correlação de Pearson (r=0,995). Todos os MDEs avaliados neste estudo apresentaram morfologia próxima a do MDE fotogramétrico. Portanto, recomenda-se o uso de todos os MDEs analisados em estudos morfométricos da área de estudo, sendo necessário observar o objetivo do trabalho, bem como a escala de análise e a apresentação desses dados.This work aims to evaluate the vertical accuracy of the digital elevation models (DEMs) SRTM v.3, Alos World 3D and ASTER GDEM v.2 in Vale dos Vinhedos designation of origin (DO) region, RS. Thus, the DEM data with 30 m of the spatial resolution were compared with photogrammetric DEM data with 5 m of the spatial resolution by linear regression and correlation analyzes, and also, topographic profiles carried out with these models. The Cartographic Accuracy Standard (PEC) of each DEM was analyzed to identify the maximum scale for morphometric application, in scales 1:25.000, 1:50.000 and 1:100.000, by calculations of Vertical Tolerance and the Mean Square Error (MSE). All DEMs. All the models studied were classified in class A for the 1:100,000 scale, and for the 1:50,000 scale the analyzed models were classified in class C, while in 1:25.000 scale doesn´t have application. The DEM SRTM v.3 presented smaller altimetry errors compared to ASTER GDEM and Alos World 3D, as for mophometric analysis and Pearson correlation coefficient (r=0,995). It is worth mentioning that all models analyzed are statistically and morphologically close. Therefore, they can be used to conduct several studies, however it is necessary to have in mind the goal of the work, and the scale of analysis and presentatio

Study abroad program impacting engineering formation : cultural immersion (CIB)

The study abroad experience described in this paper has showed as one of the most effective ways to promote the retention rate in engineering programs. Among the outcomes are the dynamic addition to undergraduate career; the opportunity for long-lasting friendships; the enhancement of technical skills and knowledge; understanding the different cultures and histories and an addition to life enrichment. The main goal of the program is to provide the future engineers with tools and extra experiences to develop a career as engineers in a more adequate to the present challenging and mutant work market.(undefined
