Bearing Capacity of Tension Steel Piles in Thinly Inter‐Layered Soils: Numerical Class‐A Prediction vs. Field Measurements

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study investigates the bearing capacity of tension piles and pile‐soil interaction during loading. Discrepancies between predicted and measured bearing capacities in previous tests motivated the study, where analytical methods showed considerable scatter and uncertainties in design.

A robust numerical method for the generation and propagation of periodic finite-amplitude internal waves in natural waters using high-accuracy simulations [PDF]

Nonlinear Processes in Geophysics
The design and implementation of boundary conditions for the robust generation and simulation of periodic finite-amplitude internal waves is examined in a quasi two-layer continuous stratification using a spectral-element-method-based incompressible flow

Even-cycle decompositions of graphs with no odd-$K_4$-minor

, 2017
An even-cycle decomposition of a graph G is a partition of E(G) into cycles of even length. Evidently, every Eulerian bipartite graph has an even-cycle decomposition.

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.

Parameterized Edge Hamiltonicity

, 2014
We study the parameterized complexity of the classical Edge Hamiltonian Path problem and give several fixed-parameter tractability results. First, we settle an open question of Demaine et al.

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

CFD Analysis of a V-Shaped Desktop Fan for Near-field Control of Infected Respiratory Cloud [PDF]

E3S Web of Conferences
The respiratory cloud of an infected person contains droplets of mucosal and salivary fluid carrying germs. As this cloud spreads from the emission point, droplets accumulate, and their concentration increases in the room, unless dilution, adequate ...

Eulerian and Lagrangian Comparison of Wind Jets in the Tokar Gap Region

Fluids, 2020
The Lagrangian and Eulerian structure and dynamics of a strong wind event in the Tokar Gap region are described using a Weather Research and Forecasting (WRF) model hindcast for 2008. Winds in the Tokar Gap reach 25 m s−1 and remain coherent as a jet far
