This paper presents the methodological approach for structurally restoring a highly damaged XVIIIth century building, the former military compound “Caserma Principe Amedeo”, in view of its reutilization as House of Justice of the city of Nola, near Naples. The building was designed by one of the most important architects who operated in Naples at that time: Ferdinando Fuga. Today, its structure...
Building damage such as to side-walls or mid-story collapse is often overlooked in vertical optical images. Hence, in order to observe such building damage modes, high-resolution SAR images are introduced considering the side-looking nature of SAR. In the 2011 Tohoku, Japan, earthquake, a large number of buildings were collapsed or severely damaged due to repeated tsunamis. One of the important...
The 2002 Molise earthquake, which was defined by seismologists as a normal event in the geodynamics of the Italian peninsula but had an international resonance due to the collapse of a primary school, triggered a series of research initiatives in earthquake engineering and significant modifications to building codes in Italy. The modifications were completed at the beginning of 2008 with the re...
The Adaptively Shifted Integration (ASI) technique, which produces the highest computational efficiency in the finite element analyses of framed structures including static and dynamic collapse problems, is applied to the seismic damage analysis of a reinforced concrete building. By expressing member fracture by a plastic hinge located at the exact position with a simultaneous release of result...
Starvation of cells for the DNA building block dTTP is strikingly lethal (thymineless death, TLD), and this effect is observed in all organisms. The phenomenon, discovered some 60 years ago, is widely used to kill cells in anticancer therapies, but many questions regarding the precise underlying mechanisms have remained. Here, we show for the first time that starvation for the DNA precursor dGT...
A classification algorithm is developed for evaluating the damage state of buildings subjected to earthquakes. Nonlinear response history analysis is used to generate the time histories of each building subjected to each earthquake. This report summarizes the analysis procedure used to extract data and describes the different classification algorithms that are developed to predict damage state....
Although differences exist between building software systems and building physical structures such as bridges and rockets, enough similarities exist that software engineers can learn lessons from failures in traditional engineering disciplines. This paper draws les sons from two well-known failures—the collapse of the Tacoma Narrows Bridge in 1940 and the destruction of the space shuttle Challe...
The tragedy of the commons predicts social collapse when public goods are jointly exploited by individuals attempting to maximize their fitness at the expense of other social group members. However, animal societies have evolved many times despite this vulnerability to exploitation by selfish individuals. Kin selection offers a solution to this social dilemma, but in large social groups mean re...
The calculating stability of an engineering structure against progressive collapse is considered in this article. calculations results are analyzed. A dangerous emergency scenario was developed and measures were to prevent the building structures local destruction accordance with regulatory documents requirements for such object. most design schemes assess collapse. case failure has been select...
Artificial Neural Network (ANN) is a valuable and well-established inversion technique for the estimation of geophysical parameters from satellite images. After training, ANNs are able to generate very fast products for several types of applications. Satellite remote sensing is an efficient way to detect and map strong earthquake damage for contributing to post-disaster activities during emerge...
