Enabling Semantically Grounded, Long Horizon Planning and Execution for Autonomous Agents
… constraint based planners while automating the environmental modeling step with an advanced semantic perception engine. By automating environmental modeling, we are able to create a system which executes complex semantically grounded tasks such as navigating to certain objects within a certain …

Towards Machine Learning-Based Control of Autonomous Vehicles in Solar Panel Cleaning Systems
… navigation among solar panel arrays. However, environmental obstacles (e.g., rough terrain), variations in solar panel installation (e.g., height disparities, different angles), and uncertainties (e.g., AV and environmental modeling) may degrade the performance of traditional controllers. In …

Towards applied modeling of the human-eco-system an approach of hydrology based integrated modeling of a semi-arid sub-catchment in rural north-west India
… common impacts. State of the art in hydrologic environmental modeling is generally operating under a reductionist paradigm (Sivapalan 2005). Even an enormous quantity of process-oriented models exists, we fail in due reproduction of complexly interacting processes in their effective scale in the …

Studying coupled human and natural systems from a decentralized perspective: the case of agent-based and decentralized modeling
… review of the literature shows that agent-based modeling is a commonly used tool in all the fields related to coupled human and natural systems such as socio-ecology – or social and ecological systems, hydro-economic systems, socio-hydrology or integrated environmental modeling. While agent-based …
