Predictive energy-efficient motion trajectory optimization of electric vehicles

This work uses a combination of existing and novel methods to optimize the motion trajectory of an electric vehicle in order to improve the energy efficiency and other criteria for a predefined route. The optimization uses a single combined cost function incorporating energy efficiency, travel safety, physical feasibility, and other criteria. Another focus is the optimal behavior beyond the regular optimization horizon

Healthy Placemaking - Revitalizing Springfield\u27s Medical District

Healthy Placemaking - Revitalizing Springfield’s Medical District Healthy Placemaking for the North End Medical District was a community engagement urban design studio for Springfield, MA to propose a new vision for the Medical District as an exemplary model of healthy place-making. WHAT IS HEALTHY PLACE-MAKING? Healthy place-making is a creative process that generates an interconnected mixture of amenities that activate the public realm, creating a livelihood that builds upon sense of place. Urban design strategies consider the ecological relationship between people and the environment in order to provide design interventions that improve the mental, physical, social, and economic wellbeing of inhabitants. Contextually rooted in the history of the area, new and adapted development illustrates environmentally responsible initiatives. EXISTING CONDITIONS 1. No Sense of Place 2. Weak Connections 3. No Mix of Uses and Amenities 4. Unhealthy Environment STUDIO PROCESS AND COMMUNITY ENGAGEMENT Meetings with diverse stakeholders – residents, community leaders, employees in the medical industry- led to a better understanding of assets, challenges and goals from different perspectives. Listening to their ideas was influential for developing the design program. DESIGN STRATEGIES AND OBJECTIVES 1. Enhance the Sense of Place The designs create a sense of place through Landscape Architecture for playing and gathering and the enjoyment of the beauty and healing of plants. 2. Increase Connections The designs create new green connections to work, school and nature in the city. 3. Provide a Balance of Amenities A variety of amenities are introduced into the urban fabric to activate the street life while also stimulating the local economy. 4. Green Infrastructure as a Framework for Public Health Green infrastructure and public health are intrinsically linked: stormwater management, tree canopy, pervious surface cover, and public open space. PLACE-ORIENTED DESIGN PROPOSALS The work explores design proposals for three different places: DESTINATION WASON RIVERSIDE creates two new destinations on the edge of the Connecticut River that engage people and plants, BRIGHTWOOD’S MEDICAL EDGE designs a livable neighborhood with a mix of amenities, gathering places, infill for housing and a remodeled industrial edge to mitigate the impact for residents and to improve the services, and HEALTHY SPACES FOR HEALTHY PEOPLE designs a walkable, green Medical Campus with the framework of the healing landscape

Learning to Coordinate with Anyone

In open multi-agent environments, the agents may encounter unexpected teammates. Classical multi-agent learning approaches train agents that can only coordinate with seen teammates. Recent studies attempted to generate diverse teammates to enhance the generalizable coordination ability, but were restricted by pre-defined teammates. In this work, our aim is to train agents with strong coordination ability by generating teammates that fully cover the teammate policy space, so that agents can coordinate with any teammates. Since the teammate policy space is too huge to be enumerated, we find only dissimilar teammates that are incompatible with controllable agents, which highly reduces the number of teammates that need to be trained with. However, it is hard to determine the number of such incompatible teammates beforehand. We therefore introduce a continual multi-agent learning process, in which the agent learns to coordinate with different teammates until no more incompatible teammates can be found. The above idea is implemented in the proposed Macop (Multi-agent compatible policy learning) algorithm. We conduct experiments in 8 scenarios from 4 environments that have distinct coordination patterns. Experiments show that Macop generates training teammates with much lower compatibility than previous methods. As a result, in all scenarios Macop achieves the best overall coordination ability while never significantly worse than the baselines, showing strong generalization ability

Voltage regulation strategy for alternating current microgrid under false data injection attacks

This study introduces a robust strategy for regulating output voltage in the presence of false data injection (FDI) attacks. Employing a hierarchical approach, we disentangle the distributed secondary control problem into two distinct facets: an observer-based resilient tracking control problem and a decentralized control problem tailored for real systems. Notably, our strategy eliminates the reliance on global information and effectively mitigates the impact of FDI attacks on directed communication networks. Ultimately, simulation results corroborate the efficacy of our approach, demonstrating successful voltage regulation within the system and proficient management of FDI attacks
