Clinical Severity Score System in Dogs with Degenerative Mitral Valve Disease [PDF]

open access: yes, 2015
BACKGROUND: Several risk factors already have been determined for dogs with degenerative mitral valve disease (DMVD). Risk factors often have been considered in isolation and have not always taken into account additional information provided by the ...

Demographic analysis of continuous‐time life‐history models [PDF]

open access: yesEcology Letters, 2007
AbstractI present a computational approach to calculate the population growth rate, its sensitivity to life‐history parameters and associated statistics like the stable population distribution and the reproductive value for exponentially growing populations, in which individual life history is described as a continuous development through time.

Evaluation of Seismic Response of 3D Building Frame with and without Base Isolation Using Finite Element Analysis

open access: yesEngineering Proceedings, 2023
An earthquake is a force which is unpredictable and can cause serious damage to a structure and its structural components. For improved safety, the seismic design of the building should be adequate, and measures should be taken for vibration control.

Things change: Women’s and men’s marital disruption dynamics in Italy during a time of social transformations, 1970-2003 [PDF]

open access: yes, 2010
We study women’s and men’s marital disruption in Italy between 1970 and 2003. By applying an event-history analysis to the 2003 Italian variant of the Generations and Gender Survey we found that the spread of marital disruption started among middle ...

Seismic Assessment of Steel Moment Frames with Irregularity in Mass and Stiffness [PDF]

open access: yesComputational Engineering and Physical Modeling, 2018
Irregularity, consider to be one of the main reasons of buildings collapse in recent earthquakes. Irregularity also affects the seismic behavior and maximum capacity of structures.

Analysis of Seismic Wave Selection in Time History Analysis

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
By introducing a series of problems in time history analysis, such as the selection principle of input seismic wave, the amplitude and frequency characteristics of ground motion, beginners can have a preliminary understanding of the selection of input seismic wave and lay a foundation for further research.

VULNERABILITY ASSESSMENT OF MONUMENTAL ARTWORKS USING CONTACT TIME-HISTORY ANALYSIS [PDF]

open access: yesProceedings of the 8th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2021
Strategies for the protection of the Cultural Heritage priceless value are highly demanded, being both earthquake and support movement (and a combination of the two of them) severe threats for their safety and integrity. To this scope, computer-based numerical formulations have been representing a powerful tool for the simulation of expected loss in ...
