Wave–sea-ice interactions in a brittle rheological framework

چکیده

Abstract. As sea ice extent decreases in the Arctic, surface ocean waves have more time and space to develop grow, exposing marginal zone (MIZ) frequent energetic wave events. Waves can fragment cover over tens of kilometres, prospect increasing activity has sparked recent interest interactions between wave-induced fragmentation lateral melting. The impact this on dynamics, however, remains mostly unknown, although it is thought that fragmented experiences less resistance deformation than pack ice. Here, we introduce a new coupled framework involving spectral model WAVEWATCH III neXtSIM, which includes Maxwell elasto-brittle rheology. This rheological enables efficiently track keep “memory” level damage. We propose damage increases when occurs. used modelling system investigate potential such local mechanism kinematics. Focusing Barents Sea, found internal stress decrease resulting from its by resulted dynamical MIZ, particularly areas where compact. Sea drift enhanced for both on-ice off-ice wind conditions. Our results importance considering wave–sea-ice forecast applications. They also suggest likely modulate area advected away ocean, potentially contributing observed past, current future decline Arctic.

Textural and rheological properties of stevia ice cream

Ice cream contains high sugar content and therefore it is in contradiction with the concept of healthy diet. The objective of this study is to determine the suitability of using stevia as an alternative natural sweetener in making ice cream. Inhouse ice cream formulation (as the control) and three different concentrations of stevia ice cream formulations of (A, B and C) were used. Physical prop...

Rheological Characteristics of Ice Slurries Based on Propylene- and Ethylene-Glycol at High Ice Fractions

Abstract—Ice slurries are considered as a promising phasechanging secondary fluids for air-conditioning, packaging or cooling industrial processes. An experimental study has been here carried out to measure the rheological characteristics of ice slurries. Ice slurries consist in a solid phase (flake ice crystals) and a liquid phase. The later is composed of a mixture of liquid water and an addi...

ICE: A Robust Framework for Learning Invariants

We introduce ICE, a robust learning paradigm for synthesizing invariants, that learns using examples, counter-examples, and implications, and show that it admits honest teachers and strongly convergent mechanisms for invariant synthesis. We observe that existing algorithms for black-box abstract interpretation can be interpreted as ICE-learning algorithms. We develop new strongly convergent ICE...
