Development of a Pilot Soil-Water Balance Model for Determination of Probability of a Working Day for Rice Harvesting

open access: yesActa Technologica Agriculturae, 2021
The probability of a working day is the ratio of workable days to the total available days in a working season for the intended operation. Soil moisture is the most important limiting factor in terms of rice harvesting.

Physical properties of a Brazilian sandy loam soil after the traffic of a military vehicle M113 BR [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2020
Soil physical properties can be changed after vehicle traffic, especially by heavy military tracked vehicles. The Santa Maria military Instruction Field, where the experiment was carried out, is currently the most used area for armored tracked vehicles ...

EFFECT OF RICE STUBBLE ON SOIL COMPACTION PROPERTIES OF A CRAWLER UNDERGOING COMBINE HARVESTER HARVESTING

open access: yesEngenharia Agrícola, 2023
In the process of rice harvesting, the passability of the track combine harvester is often limited by the state of the soil. Meanwhile, wet and soft paddy soil is compacted under the rolling of harvesting machinery, which also affects the soil function ...

A Multilevel Adaptive Path-Planning Model in Off-Road Environments

open access: yesApplied Sciences, 2022
Most existing path-planning algorithms are applied in either trafficable environments or non-trafficable environments. Off-road vehicles (ORVs) are often faced with a mix of trafficable and non-trafficable environments.

Open Traffic: A Toolbox for Traffic Research

open access: yesProcedia Computer Science, 2014
AbstractOpen Traffic is an open source software project that provides a transport modeling software environment. While most transport model packages offer ready-to-use modules for end-users, Open Traffic provides open access to a modelling environment for the (further) development of methods and algorithms and enables the sharing, distribution and ...

Traffic Control Through Traffic Density

open access: yes2019 3rd European Conference on Electrical Engineering and Computer Science (EECS), 2019
The article is focused on dynamic driving in road transport. Current systems on the market are referred to as dynamic but have their limitations. Traffic management is an important aspect to ensure the proper functioning and safety of transport as an element of critical infrastructure.

Accessibility Data Set for Large Permanent Cold Traps at the Lunar Poles

open access: yesEarth and Space Science, 2020
Many large cold traps exist at both lunar poles where temperatures never exceed 110 K annually, allowing the preservation of water ice. Much has been learned about these regions from orbital measurements, but in situ access is needed to truly understand ...

Implications of Interdomain Traffic Characteristics on Traffic Engineering [PDF]

open access: yesEuropean Transactions on Telecommunications, 2002
AbstractWe study the interdomain traffic as seen by a non‐transit ISP, based on a six days trace covering all the interdomain links of this ISP. Our analysis considers the relationships between the interdomain traffic and the interdomain topology. We first discuss the day‐to‐day stability of the interdomain traffic matrix to evaluate the feasibility of

Prediction and Experimental Study of Tire Slip Rate Based on Chassis Sinkage Amount

open access: yesAgriculture, 2023
In view of the problems that the fuselage inclines and the driving straightness is difficult to guarantee due to the sinking and sliding of the wheels when the high-clearance plant protection machine is working in the paddy field, this paper takes high ...

Design of a New Sensor for Determination of the Effects of Tractor Field Usage in Southern Spain: Soil Sinkage and Alterations in the Cone Index and Dry Bulk Density

open access: yesSensors, 2012
Variations in sinkage and cone index are of crucial importance when planning fieldwork, and for determining the trafficability of farm machinery. Many studies have highlighted the link between higher values of these parameters and dramatic decreases in ...
