Método de Levantamento Topo-Batimétrico do Perfil do Sistema Praia-Antepraia

Revista Brasileira de Geomorfologia, 2004
É apresentada uma metodologia de levantamento topo-batimétrico visando o acoplamento do perfil da praia ao perfil submarino da antepraia, a partir de um mesmo datum vertical de referência em terra, transposto por nivelamento para o ajuste do ecobatimetro,

Linear Boltzmann dynamics in a strip with large reflective obstacles: stationary state and residence time

, 2017
The presence of obstacles modify the way in which particles diffuse. In cells, for instance, it is observed that, due to the presence of macromolecules playing the role of obstacles, the mean square displacement ofbiomolecules scales as a power law with ...

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic

Ecology, Volume 107, Issue 5, May 2026.
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging

The end stage of barrier estuary infill: Insights from Jack Smith Lake, Southeastern Australia

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Infill model for the saline coastal lake estuary, Jack Smith Lake. Abstract Jack Smith Lake in southeastern Australia is an infilled saline coastal lake, disconnected from the ocean by a foredune barrier. This study explores the Holocene infill history of this estuary in order to understand the end‐stage evolution of barrier estuarine systems with ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

On the geoid and orthometric height vs. quasigeoid and normal height

Journal of Geodetic Science, 2018
The geoid, but not the quasigeoid, is an equipotential surface in the Earth’s gravity field that can serve both as a geodetic datum and a reference surface in geophysics. It is also a natural zero-level surface, as it agrees with the undisturbed mean sea
