Control System for the Navigation of the Agricultural Robots: A Review
Journal of Field Robotics, EarlyView.ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Sustainable Development, EarlyView.ABSTRACT Achieving Agenda 2030 depends on addressing interactions between the sustainable development goals (SDGs). In this paper, we conceptualize SDG interactions as synergies or trade‐offs, incoming or outgoing, and internal or external, and analyze how SDG 2 (Zero Hunger) interacts with other SDGs within and across policy programmes that support ...

Roof stability analysis model of super-long fully mechanized working face and its application
Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesAbstract The strata behavior of a fully mechanized working face is obviously different from that of a short working face after the dip length of the coal face is lengthened. In view of the characteristics of high frequency, high peak value and large range of weighting in super-long working faces, a mechanical analysis model based on elastic foundation ...

Social Sustainability in Circular Bioeconomy Business Models: Insights From Argentina
Sustainable Development, EarlyView.ABSTRACT Research on circular bioeconomy business models (CBEBM) has largely prioritised environmental and economic aspects, leaving out the social pillar. To address this gap, this paper analyses to what extent and in what ways social sustainability is integrated into CBEBM, based on 12 cases from northern Argentina, a region with high potential for ...

"Productivity in Manufacturing and the Length of the Working Day: Evidence from the 1880 Census of Manufactures" [PDF]
Data from the manuscript census of manufacturing are used to estimate the effects of the length of the working day on output and wages. We find that the elasticity of output with respect to daily hours worked was positive but less than one--implying ...
