Assessment of spatial variability of bedding variables in compost bedded pack barns with climate control system [PDF]
Anais da Academia Brasileira de Ciências, 2021 The aim of this research was to evaluate the spatial distribution of bedding variables in a climate-controlled compost bedded pack barn (CBP) equipped with an evaporative cooling system associated with a tunnel ventilation mode.

On the Control of Soil Heterogeneity, Peclet number and Spatially Variable Diffusion over Unsaturated Transport [PDF]
Water Resources Research, 2022 Physical properties of soils are ubiquitously heterogeneous. This spatial variability has a profound, yet still partially understood, impact on conservative transport. Moreover, molecular diffusion is often a disregarded process that can have an important counter-intuitive effect on transport: diffusion can prevent non-Fickian tailing by mobilizing ...

Variable spatial springs for robot control applications [PDF]
Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems. Expanding the Societal Role of Robotics in the the Next Millennium (Cat. No.01CH37180), 2002 This article presents a passive way to implement varying spatial springs. These are springs with controlling ports which can be used to modify their spatial rest length or spatial properties. These controlling ports have a dual structure which allows one to supervise the potential energy injected into the spring by varying its properties.

Global analysis of the controls on seawater dimethylsulfide spatial variability
Biogeosciences, 2023 Abstract. Dimethylsulfide (DMS) emitted from the ocean makes a significant global contribution to natural marine aerosol and cloud condensation nuclei and, therefore, our planet's climate. Oceanic DMS concentrations show large spatiotemporal variability, but observations are sparse, so products describing global DMS distribution rely on interpolation ...

Spatial and temporal variability of shorefaces: A morpho-hydrodynamic controlled system [PDF]
Estuarine, Coastal and Shelf Science, 2023 Shorefaces are transitional zones between the shelf and surfzone/beach systems. They are subdivided into ‘upper’ and ‘lower’ shoreface sectors which display particular morphodynamic behaviour, with the upper shoreface morphologically active over short (annual) time scales, and the lower shoreface evolving over much longer time scales (decadal and ...

Spatial and layer-controlled variability in fracture networks [PDF]
Journal of Structural Geology, 2018 Abstract Topological sampling, based on 1) node counting and 2) circular sampling areas, is used to measure fracture intensity in surface exposures of a layered limestone/shale sequence in north Somerset, UK. This method provides similar levels of precision as more traditional line samples, but is about 10 times quicker and allows characterization of

Hierarchical global fast terminal sliding‐mode control for a bridge travelling crane system
IET Control Theory & Applications, 2021 The bridge crane system is a typical under‐actuated system that is widely used in production and life. Although various scholars have conducted extensive research on the bridge crane system in recent years, there are still many problems, such as the ...
