Developing a global risk engine

Risk analysis is a critical link in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment software. However, there is a significant disparity between the high quality scientific data developed by researchers and the availability of versatile, open and user-friendly risk analysis tools to meet...

Seismic risk assessment of adobe dwellings in Cusco, Peru, based on mechanical ...

A procedure to evaluate the seismic vulnerability of one-storey adobe dwellings located in Cusco (Peru) is presented here. The seismic capacity of these dwellings is based on a mechanical-based approach, where the in-plane and out-of-plane failure mechanisms are taken into account. From a database with the principal geometrical properties of dwellings from Cusco, random populations of buildings were generated t...

Structural properties of adobe dwellings in Cusco for seismic risk assessment

According to the last national census, 35% of the Peruvian dwellings are made with adobe or tapial (rammed earth). In Cusco, a city located at the Peruvian highlands, around 75% of the building stock is constructed with earth. Besides, Cusco is relatively seismically active and thus seismic risk assessment studies are warranted. For example, on May 21, 1950, an earthquake seriously damaged almost all the buildi...

Seismic capacity of adobe dwellings

In this paper the seismic capacity of adobe dwellings, in-plane and out-of-plane, is analyzed in terms of the displacement capacity and the period of vibration. For the former, cyclic and dynamic tests carried out at the Catholic University of Peru (PUCP) has been analyzed to obtain limit states (LS) for adobe walls and damping values for each LS. The period of vibration obtained from the experimental test resu...

Parámetros estructurales de las viviendas de adobe (Cusco, Perú) para la evalua...

En este trabajo se evalúan las propiedades estructurales de las construcciones de adobe en Cusco, Perú, para ser usadas como parámetros en la evaluación de la capacidad y del riesgo sísmico. Las propiedades geométricas (tipología) de las viviendas de adobe han sido determinadas a través de encuestas de campo en un trabajo anterior. Con la información recopilada se creó una base de datos resaltando la media, des...

Structural properties of adobe dwellings in Cusco (Peru) for seismic risk asses...

This paper looks at the structural properties of adobe buildings in Cusco, Peru, for use in seismic risk assessment. The geometrical properties (typology) of adobe dwellings from Cusco have been established according to a building-by-building survey. Cusco has been chosen for this study as, according to the national census, around 80% of the building stock in this town is constructed with adobe. Furthermore, th...

Profilaxia de Úlceras de Stresse numa Unidade de Cuidados Intensivos: estado da...

As lesões da mucosa gastro-duodenal relacionadas com o stresse fisiológico são frequentes nos doentes internados em unidades de cuidados intensivos. Podem condicionar hemorragia digestiva com repercussão hemodinâmica, estando associadas a aumento da mortalidade. A hipoperfusão esplâncnica tem um papel central na sua fisiopatologia. Foram identificados vários factores de risco para a sua ocorrência, sendo os ma...

Identificação e quantificação de tocoferóis por HPLC em Croton adamantinus (Eup...

Há muito interesse atualmente em se conhecer a composição química de óleos vegetais de sementes, visando encontrar espécies alternativas às oleaginosas tradicionais para serem utilizados tanto na indústria oleoquímica como na alimentícia. Croton adamantinus Mull. Arg. é uma Euphorbiaceae arbustiva, nativa e abundante do semi-árido do Nordeste do Brasil, cujas sementes têm 37 % de óleo com, respectivamente, 44 ...

Efficient Approximation of the Mahalanobis Distance for Tracking with the Kalma...

In this paper, we address the problem of tracking feature points along image sequences efficiently. Thus, to estimate the undergoing movement we use an approach based on Kalman filtering, which performs the prediction and correction of the features’ movement in every image frame. Measured data is incorporated by optimizing the global association set built on efficient approximations of the Mahalanobis dis...
