Abstract:
Discontinuous shear thickening (DST) is associated with a sharp rise in a suspension’s viscosity with increasing applied shear rate or stress. Key signatures of DST, highlighted in recent studies, are the very large fluctuations of the measured stress as the suspension thickens with increasing rate. A clear link between microstructural development and the dramatic increase in stress fluctuations has not been established yet. To identify the microstructural underpinnings of this behavior, we perform simulations of sheared dense suspensions. Through an analysis of the particle contact network, w

Abstract:
We investigate via Monte Carlo simulations the kinetically constrained Kob-Andersen lattice glass model showing that, contrary to current expectations, the relaxation process and the dynamical heterogeneities seems to be characterized by different time scales. Indeed, we found that the relaxation time is related to a reverse percolation transition, whereas the time of maximum heterogeneity is related to the spatial correlation between particles. This investigation leads to a geometrical interpretation of the relaxation processes and of the different observed time scales.

Abstract:
Agricultural water scarcity is a global problem and this reinforces the need for optimal allocation of irrigation water resources. However, decision makers are challenged by the complexity of fluctuating stream condition and irrigation quota as well as the dynamic changes of the field water cycle process, which make optimal allocation more complex. A two-stage chance-constrained programming model with random parameters in the left- and right-hand sides of constraints considering field water cycle process has been developed for agricultural irrigation water allocation. The model is capable of g

We perform a gas gun experiment by shock loading tantalum samples of varying grain structures to assess the suitability of a numerical model for simulating spall behavior. The observed differences in spall strength, as well spallation and re-compression history, are not captured in uncalibrated hydrodynamic simulations. An optimization is performed on the Johnson spall model to determine the best parameters that fit the observed trends. Linear stability analysis is employed to motivate bounds on those parameters. Herein, optimized simulations agree well with the experimental results, reproduci

Les modèles aux contraintes cinétiques ont été introduits dans les années 80 pour modéliser la transition liquide-verre, dont la compréhension reste toujours un des plus grands problèmes de la physique de la matière condensée. Ils ont été depuis profondément étudiés par des physiciens dans l'espoir d'éclaircir ce problème et la communauté mathématique s'en intéresse de plus en plus lors de la dernière

Cette thèse étudie la classe de systèmes de particules en interaction appelés modèles avec contraintes cinétiques (KCM). La première question considérée est celle de l’universalité : peut-on classer l’infinité de modèles possibles en un nombre fini de classes selon leurs propriétés ? Un tel résultat a été récemment démontré dans une classe de modèles proche, la percolation bootstrap, où les modèles se subdivisent en surcritiques, critiques et sous-critiques. Cette classification s’applique aussi aux KCM, mais elle n’est pas assez fine : les KCM surcritiques doivent être subdivisés en enracinés

Abstract:
AbstractIn a framework of multiple services supplied simultaneously by forests, the protection against natural hazards is one of the most important. Forests deliver conservation of natural resources, including soil and water, and other environmental services. They slow water dispersion and allow for infiltration and percolation of rainwater, which recharges soil and underground water storage. Forest cover, moreover, protects soil from wind and water erosion, avalanches and landslides. INFC collects a wide range of information related to the protective function of Italian wooded areas. This chapter shows estimates regarding such physical site characteristics, as slope, land position and aspect which, together with tree canopy coverage and terrain roughness, can condition the protective role of forests. Inventory statistics on terrain instability and hydrogeological constraint, as defined by national laws, are shown as well, the latter being a basis of most national and regional regulations on forest management. Finally, the presence of a primary designated management objective has been assessed with a particular focus on direct and indirect protection. Estimates on such attributes are shown in the last section of this chapter.

Abstract:
Abstract Past discussions of core formation are incorrect or incomplete because they assume that metallic iron­ rich liquid is able to migrate through a mostly solid silicate matrix by percolation, prior to macrosegregation and diapiric descent. Experimental and theoretical considerations suggest that percolation is largely prevented because of the high surface tension of iron. Two alternative views of core formation are offered. One assumes that percolation is possible in the deep mantle ( where perovskite is the major phase). Iron is then supplied to the deep mantle by Rayleigh-Taylor instabilities of a silicate­ iron suspension in the shallow mantle, and drains efficiently from the deepest mantle into the core by Darcy flow. The other model assumes complete or nearly complete melting of all or part of the mantle. Despite vigorous convection, iron droplets approximately one centimeter in radius are predicted and settle rapidly by Stokes flow, either to the core or into a layer or ponds that provide iron-rich diapirs that can descend to the core. These stories generally suggest very efficient core formation in the sense that the t}pical residence time of metallic iron in the mantle is orders of magnitude shorter tban the formation time of Earth (-108 years). Good chemical equilibrium between mantle and core phases is also predicted in many cases. Geochemical constraints and implications relevant to these scenarios are discussed but are largely inconclusive. The tentative inference of rapid core formation on Mars suggests a magma ocean and iron rainout.

Abstract:
Conventional coarse particle hydraulic conveying is performed under turbulent flow conditions, usually at concentrations of less than 40% v/v. The last three or four decades have seen the development of much higher concentration conveying, with the successful transport of suspensions of 70% v/v or more. These suspensions can be conveyed at very low velocities and generally exhibit very benign characteristics, having the capability of being stopped and restarted at will. There are generally two methods of pumping coarse materials safely at low velocities. The first method, using a Newtonian such as water, can be applied when the particle size distribution is sufficiently broad to minimize percolation and the concentration sufficiently high to prevent particle restructuring during transport. A second method uses a non-Newtonian, visco-plastic carrier fluid, normally fine particle slurry, to convey the coarser particles. This second method removes the constraints of the first method, allowing a greater range of coarse solid distributions and concentrations to be pumped. In both cases, the conveying characteristics appear similar to laminar flow. Both methods are described and analyzed in this chapter.

ABSTRACT Fluid flow through faults controls subsurface transport processes, considerably impacting seismic hazards and geoengineering such as enhanced geothermal systems (EGS). Recent advances in geophysical techniques have detected changes in electrical resistivity and seismic velocity due to crustal stress changes, and possibly predicted the changes in subsurface fluid flow. However, we could not quantitatively interpret these geophysical monitoring data due to the absence of rock physical models for fractured rocks.

Sustainable water resource management is essential as urbanization and population growth intensify competition for limited freshwater resources. Accurate streamflow estimation in river basins is a key tool for effective management. Hydrologic modelling provides a flexible approach for estimating streamflow, but its application can be challenging in ungauged basins due to data scarcity and other constraints. This research improves streamflow estimation in data-scarce regions, aiding more effective water resource management amid rising demands. This research explores the applicability of the spa
