THE UNIFIED SOIL CLASSIFICATION SYSTEM MAPPING OF THE PANNONIAN BASIN IN CROATIA USING MULTINOMINAL LOGISTIC REGRESSION AND INVERSE DISTANCE WEIGHTING INTERPOLATION

open access: yesRudarsko-geološko-naftni Zbornik, 2023
The Unified Soil Classification System (USCS) is the basis for numerous methods for soil trafficability research. Since USCS data are not always available, various other data and methods are used to correlate and predict the USCS soil group.

Analysis and Experiment of a Bioinspired Multimode Octopod Robot

open access: yesChinese Journal of Mechanical Engineering, 2023
Legged robots use isolated footholds to support, which have the merit of good terrain trafficability but lack speed ability. In contrast, wheeled robots have the advantages of high speed and efficiency but only run on flat roads.

Dynamic path planning of autonomous mobile robot in off-road environments using experience replay enhanced distributed proximal policy optimization algorithm

open access: yesGeo-spatial Information Science
In off-road environments, some problems like insufficient consideration of environmental trafficability, difficulty in model convergence, and limited generalization often exist in autonomous mobile robot (AMR) path planning research based on ...

DTM models to enhance planning of timber harvesting [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2015
This paper studies the applicability of DTM with the resolution of 4 × 4 m for the analysis of macro-topographic factors (terrain slope, aspect, terrain ruggedness index) and one part of micro-topographic factors (occasional and constant streams)

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Estimation of Traffic Matrices for LRD Traffic

open access: yes, 2012
The estimation of traffic matrices in a communications network on the basis of a set of traffic measurements on the network links is a well-known problem, for which a number of solutions have been proposed when the traffic does not show dependence over time, as in the case of the Poisson process.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Current-Based Analysis and Validation of a Wheel–Soil Interaction Model for the Trafficability of a Planetary Rover

open access: yesAerospace
The assessment of trafficability for planetary rovers in relation to non-geometric hazards is a crucial issue in deep space exploration. This study relies on terramechanics theory and incorporates actual data from Mars soil and rover parameters to ...
