Seismic Simulation and Base Sliding of Concrete Gravity Dams

, 2010
A simplified procedure to estimate possible base sliding of concrete gravity dams induced by an earthquake is proposed on the basis of results obtained by parametric analysis. A simple mechanical model is developed to take into account the most relevant parameters influencing seismic response such as dam-water and dam-foundation interaction.

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

Stochastic inversion of deformation moduli of concrete dam body and foundation based on Markov chain Monte Carlo method

Shuili Shuiyun Gongcheng Xuebao, 2020
In view of the large number of uncertainties in the inversion of mechanical parameters of concrete dam materials, the Markov chain Monte Carlo (MCMC) stochastic inversion method for elastic modulus of the dam body and deformation modulus of the dam ...

EVICT, NEGLECT, OR INVEST? Community Power and the Politics of Urban Informality Governance in Jakarta

International Journal of Urban and Regional Research, EarlyView.
Abstract Why do some informal neighborhoods receive public investment while others are neglected or evicted? This article addresses the inconsistent governmental responses to informal settlements in Jakarta, Indonesia, during the democratic period. State actions range from violent evictions to tolerance and community‐led improvements.

Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis

Computer Graphics Forum, EarlyView.
In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40

Bovines, buffers and barriers: A social scientific perspective on rewilding in the Kavango‐Zambezi Transfrontier Conservation Area

Conservation Science and Practice, EarlyView.
Rewilding is often summarized with the three C's of Carnivores, Cores and Corridors. In this essay we propose a complementary perspective that focuses on the three B's of Bovines, Buffers and Barriers. This complementary perspective draws attention to rewilding as a social (rather than only ecological) challenge and is illustrated with insights from ...
