How can the pursuit-evasion game be modeled as a multi-agent reinforcement learning problem in UAVs?
5 answers
The pursuit-evasion game can be modeled as a multi-agent reinforcement learning problem in UAVs by using a variant of the Multi-Agent Deep Deterministic Policy Gradient (MADDPG) method within a Multi-Agent Reinforcement Learning (MARL) framework. This approach addresses scenarios with multiple evasive targets in non-stationary and unknown environments with random obstacles. The pursuers in the game have heterogeneous roles, allowing for enhanced exploratory actions and exploitation of previously identified targets. The algorithm also incorporates a Voronoi-based rewarding policy to facilitate exploration for possible targets. The proposed method has been implemented, tested, and validated in both simulation environments and real-world multi-robot systems comprising of UAVs. The results demonstrate that the multi-agent pursuit team can learn highly efficient coordinated control policies for target tracking and exploration, even in complex environments with multiple fast evasive targets.

How to decompose weather-dependent electricity consumption of households?
5 answers
Weather-dependent electricity consumption of households can be decomposed using various methods proposed in the literature. One approach is to develop separate models for daily maximum (peak) and minimum (idle) consumption. Another method involves disaggregating total household electricity use into different load categories/parameters such as base load, activity load, heating season gradient, cooling season gradient, and lowest external temperature at which air-conditioning is used. A two-stage model can also be used, where the first stage divides consumption into weather- and illumination-related and residual consumption, and the second stage disaggregates residual consumption into consumptions by different groups of appliances. Additionally, an extended version of cooling degree days (ECDD) has been proposed to better characterize the relationship between warm-season electricity consumption and weather conditions, taking into account temperature, residual temperature, and specific humidity effects. These methods provide valuable insights for understanding and managing weather-dependent electricity consumption in households.
To what extent does technological development contribute to climate change In asia?
3 answers
Technological development plays a significant role in contributing to climate change in Asia. The region's agriculture sector, particularly rice production, is a major source of greenhouse gas (GHG) emissions, including methane and carbon dioxide, due to the increased use of synthetic fertilizers and energy for irrigation. Additionally, the use of polluting energy sources and the lack of green technologies worsen global warming and climate damage. However, there is potential to mitigate these emissions through the adoption of climate-smart agriculture, energy efficiency measures, and sustainable consumption practices. The integration of policies at multiple levels and the implementation of regulatory and incentive mechanisms are crucial for achieving the climate goals outlined in the Paris Agreement and the United Nations' Sustainable Development Goals.
