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

Factors influencing hysteresis characteristics of concrete dam deformation
Water Science and Engineering, 2017 Thermal deformation of a concrete dam changes periodically, and its variation lags behind the air temperature variation. The lag, known as the hysteresis time, is generally attributed to the low velocity of heat conduction in concrete, but this ...

Nonlinear Analysis Of Failure Mechanism Of Roller Compacted Concrete Dam [PDF]
, 2008 Seismic effects have frequently caused damage to concrete dams. The consequences of a large dam failing can be disastrous, due to large amounts of damage of properties and human lives.

Journal of Agrarian Change, EarlyView.ABSTRACT Large‐scale irrigation schemes are central to agrarian transformation in sub‐Saharan Africa, yet their political implications are often reduced to questions of land redistribution or agrarian differentiation. Although existing scholarship has documented how irrigation restructures agrarian relations and generates dispossession, less attention ...

Massive Gravity: Exorcising the Ghost [PDF]
, 2010 We consider Higgs massive gravity [1,2] and investigate whether a nonlinear ghost in this theory can be avoided. We show that although the theory considered in [10,11] is ghost free in the decoupling limit, the ghost nevertheless reappears in the fourth ...

Policy Studies Journal, EarlyView.ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

The use of FLAC for the seismic evaluation of a concrete gravity dam including dam-water-sediments-foundation rock interaction [PDF]
, 2017 Seismic safety of 65m-high Licodia Eubea gravity dam located in Southeastern Sicily (Italy) has been assessed by means of advanced dynamic analyses of the tallest cross-section of the dam. The analyses were performed with two-dimensional, plane strain,
