Historic buildings are the cultural and traditional identity of a country. However, these vulnerable to earthquakes because their aged structure, poor maintenance, inadequate structural health monitoring. Therefore, seismic vulnerability assessment is critical aspect in restoration retrofitting heritage buildings. In this study, comprehensive survey was performed collect data old historic churc...

The seismic vulnerability of existing RC framed buildings in seismic-prone areas requires affordable and practice-oriented solutions for their retrofitting. In this paper, the authors present a retrofitting solution based on combined use cross-laminated timber (CLT) panels asymmetric friction connections (AFCs). AFC connection is activated when force level reaches design threshold. energy dissi...

Seismic risk scenarios are obtained for an informal settlement in Mérida (Venezuela), which is representative of an important number of urban areas in earthquake-prone regions of the developing world. The vulnerability indices of the buildings range between 0.64 and 0.80 on a scale of 0 to 1. In an intensity IX earthquake scenario, more than 32% of the buildings would suffer damage of grade 4 (...

Seismic retrofitting of under-designed structures is a consolidated approach to risk management. Several options are available for the achievement of the vulnerability reduction goals, each of those having peculiar performances in respect of different technical and non-structural criteria. Selection of the best solution is a non-trivial task, because criteria may conflict each other. MultiCrite...

Land degradation has expanded in the Mediterranean region as a result of a variety of factors, including economic and population growth, land-use changes and climate variations. The level of land vulnerability to degradation and its growth over time are distributed heterogeneously over space, concentrating on landscapes exposed to high human pressure. The present study investigates the level of...

Traditional building retrofitting planning is a decision making process prior to the building retrofitting investment. Although the long term energy and financial issues of the retrofitting project are considered in some cases, the energy efficiency potentials due to the maintenance and operation of the retrofitted facilities are not sufficiently explored in existing studies. In the broad field...

In this article, a modeling process is defined to address challenges in analyzing attack scenarios and mitigating vulnerabilities in networked environments. Known system vulnerability data, system configuration data, and vulnerability scanner results are considered to create exploitation graphs (e-graphs) that are used to represent attack scenarios. Experiments carried out in a cluster computin...

By 2011, the Integrated Circuit(IC) feature sizes are expected to be reduced to 22nm from present day 45nm, and the soft error rate will increase by 3 to 4 orders of magnitude (from one per year to one per hour). International Technology Roadmap for Semiconductors(ITRS) indicates that techniques for mitigating soft errors are crucial for future generations of Integrated Circuits. Soft errors ar...
