Nowadays, cities are increasingly required to be smart, sustainable, resilient and adaptive and, particularly following the COVID-19 pandemic, an integrated approach to transport planning needs to be adopted. In fact, European policies have adopted a series of limitations in the transport sector that led the scientific community to put into question the traditional transport planning process, by accelerating processes close to sustainability, started some time ago. In fact, many efforts in terms of strategies, initiatives and research have been made in the last decade to enhance new forms of sustainable urban mobility, in order to reduce the externalities associated with the transport sector. To achieve this goal, the European Commission has emphasized the integrated planning at all mobility levels. Among the other instruments, it has been identified a key role in the writing of the Sustainable Urban Mobility Plan (SUMP), its management and also through Intelligent Transport Systems (ITS). Based on this premise, the aim of this paper is to present first results of a wider research aimed at investigating the methodological and practical approaches to boost the strategy of integration between transport systems and urban planning by using ITS technologies and infomobility systems. The research can support further investigations in order to define specific Key Performance Indicators (KPIs) to measure and monitoring the impacts of technologies on developing smart cities and promoting sustainable mobility approaches, facing the urban planning and transport mobility issues of modern society.

Advancing agrivoltaics within the U.S. legal framework: A multidimensional assessment of barriers & opportunities

引用

AIP Conference Proceedings 2022年第1期2635卷

作者： Alexis S. Pascaris Chelsea Schelly Joshua M. Pearce 1Department of Social Sciences Michigan Technological University 1400 Townsend Drive Houghton MI 49931 USA 2Department of Electrical & Computer Engineering Western University 1151 Richmond St. N.

To support the broader realization of agrivoltaics in the U.S., this research provides a multidimensional assessment of the socio-political barriers and opportunities for development. A synthesis of five empirical studies is presented: 1) an investigation of the impediments to farmer adoption; 2) an exploration of development challenges from the perspective of solar industry professionals; 3) a survey gauging public support and siting preferences for agrivoltaics; 4) a life cycle assessment of a pasture-based agrivoltaic system; and 5) the development of a comprehensive legal framework for agrivoltaics in the U.S. The assessment reveals the intersectionality among key stakeholders, communities, the environment, and legal frameworks, which can inform agrivoltaic decision making, stakeholder relations, and policy design globally. The primary socio-political barriers identified include: techno-economic challenges, community resistance, lack of financial incentive for both sectors, and restrictive local land use policy. The central socio-political opportunities include: income diversification, enhanced community relations and acceptance, energy demand and emissions reduction, and policy integration between key sectors. These findings demonstrate the need for multidimensional and interdisciplinary approaches to agrivoltaic development and an increased research focus on socio-political considerations.

Lattice Boltzmann simulation of MHD non-Newtonian power-law nanofluid in a rectangular enclosure using GPU computing

引用

AIP Conference Proceedings 2021年第1期2324卷

作者： Aimon Rahman Preetom Nag Md. Mamun Molla 1Department of Electrical and Computer Engineering North South University Dhaka Bangladesh 2Department of Mathematics & Physics North South University Dhaka-1229 Bangladesh 3Center for Applied Scientific Computing (CASC) North South University Dhaka-1229 Bangladesh

In this paper, a numerical study has been conducted on the heat transfer of non-Newtonian nanofluid (Copper-Water) in a vertical rectangular cavity in the presence of a horizontal or angular magnetic field. The numerical simulation has been accomplished using the graphics process unit (GPU) accelerated multiple-relaxation-time (MRT) lattice Boltzmann method. A modified power-law model has been employed to characterize the non-Newtonian fluid behavior. The simulation presented in this paper spans a range of power-law index (0.6 ≤ n ≤ 1.0), Hartmann number (0 ≤ Ha ≤ 50) and nanoparticle volume fraction (0 ≤ φ ≤ 0.05). Results indicate that an increment of the power-law index leads to reduce the heat transfer rate from the hot walls. The heat transfer rate also drops when the Hartmann number is incremented. Moreover, augmentation of the volume fraction of nanofluids can enhance the average Nusselt number. Finally, the average Nusselt number increases when the magnetic field is applied at a different angle instead of 0°.

AIP Conference Proceedings 2021年第1期2324卷

作者： Mashnoon Islam Preetom Nag Md. Mamun Molla 1Department of Electrical and Computer Engineering North South University Dhaka Bangladesh 2Department of Mathematics & Physics North South University Dhaka-1229 Bangladesh 3Center for Applied Scientific Computing (CASC) North South University Dhaka-1229 Bangladesh

This paper demonstrates a numerical study of heat transfer in a square porous cavity filled with non-Newtonian power-law fluid. A Graphics Processing Unit (GPU) has been used to accelerate the numerical simulation, which uses the Multiple-Relaxation-Time (MRT) Lattice Boltzmann Method. A modified power-law model has been employed to characterize the flow of non-Newtonian fluids. The simulations have been conducted for the power-law index n ranging from (0.6 ≤ n ≤ 1.0), the Darcy number Da ranging from (10−3 ≤ Da ≤ 10−1) and the Raleigh number Ra ranging from (103 ≤ Ra ≤ 105). Results show that the average Nusselt number (Nu) decreases with an increase in the value of n while Nu increases with an increase in the value of Da. Moreover, an increment in the value of Ra leads to an increase in the average Nusselt number.

Exploring the use of AI in marine acoustic sensor management

Proceedings of Meetings on Acoustics 2022年第1期47卷

Underwater passive acoustic source detection and tracking is important for various marine applications, including marine mammal monitoring and naval surveillance. The performance in these applications is dependent on the placement and operation of sensing assets, such as autonomous underwater vehicles. Conventionally, these decisions have been made by human operators aided by acoustic propagation modelling tools, situational and environmental data, and experience. However, this is time-consuming and computationally expensive. We consider a ‘toy problem’ of a single autonomous vehicle (agent) in search of a stationary source of low frequency within a reinforcement learning (RL) architecture. We initially choose the observation space to be the agent’s current position. The agent is allowed to explore the environment with a limited action space, taking equal distance steps in one of $n$ directions. Rewards are received for positive detections of the source. Using OpenAI’s PPO algorithm an increase in median episode reward of approximately 20 points in the RL environment developed is seen when the agent is given a history of it’s previous moves and signal-to-noise ratio compared to the simple state. The future expansion of the RL framework is discussed in terms of the observation and action spaces, reward function and RL architecture.
