Many applications require teams of robots to cooperatively execute tasks. Among these domains are those in which successful coordination must respect intra-path constraints, which are constraints that occur on the paths of agents and affect route planning. This work focuses on multi-agent coordination for disaster response with intra-path precedence constraints, a compelling application that is...

Noise injury in agriculture is a significant yet often unrecognized problem. Many farmers, farm workers, and family members are exposed to noise levels above recommended levels and have greater hearing loss than their non-farming contemporaries. The aim of this study was to gather up-to-date information on farm noise levels and to enhance the quality of information available to assist farmers i...

Illegal gold mining (galamsey) continues to be a threat forest and water resources in Ghana. Even though galamsey is not new Ghana, the use of heavy machines such as excavators bulldozers, chanfans are recent phenomenon causing destruction forests, farmlands river bodies. undermines government’s commitment attainment 17 sustainable development goals. Governments since 1989 have made attempts cl...

Heavy mobile machinery cabs and their equipment are still not well adjusted to operators, so it is surprising that we witnessing huge consequences of accidents at sites where they operate. The checklist with 39 questions, based on the previous research, formed, its’ measurement structure has been tested sample 102 transport, construction, mining machines, including cranes, excavators, bucket wh...

The ability of the ground penetrating radar (GPR) method as a rapid preliminary survey to detect presence illegally buried waste is presented in this paper. test site located countryside “Sannicandro di Bari” (Southern Italy) and has surface area 1500 m2. A total five parallel profiles were acquired 2014 using geophysical system instrument (GSSI) equipped with 400 200 MHz antennae monostatic co...

The interpretation of metaphorical utterances often results in the attribution of emergent properties; these are properties which are neither standardly associated with the individual constituents of the utterance in isolation nor derivable by standard rules of semantic composition. For example, an utterance of ‘Robert is a bulldozer’ may be understood as attributing to Robert such properties a...

Realistic physics-based simulation of vehicles on soft terrain has increasingly gained importance due to their broad application from operator training to mission planning and design. In this work we combine models from terramechanics and soil mechanics to represent the interaction of vehicles and their tools with a deformable terrain, allowing us to simulate a broad range of vehicles, includin...

Landfill leachate recirculation is efficient in reducing the leachate quantity handled by a leachate treatment plant. However, after land application of leachate, nitrification and denitrification of the ammoniacal N becomes possible and the greenhouse gas nitrous oxide (N2O) is produced. Lack of information on the effects of leachate recirculation on N2O production led to a field study being c...

Many applications require teams of robots to cooperatively execute complex tasks. Among these domains are some that require robots to interact closely at particular times and locations to accomplish some task components, but otherwise allow the team members to act independently. Successful execution in such domains often requires agent interactions that must adhere to constraints of precedence....
