Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Effects of traffic composition on noise generated by typical Brazilian roads

open access: yesArchives of Acoustics, 2003
The effects of traffic composition on the noise generated by typical Brazilian roads are analyzed in this work Composition is defined as the percentage of heavy vehicles (trucks and buses) with respect to the overall number of vehicles ...

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Practical Methodology for Developing Visions for Carbon‐Neutral Cities and Communities

open access: yesSustainable Development, EarlyView.
ABSTRACT Cities and communities play important roles in sustainable development and climate change mitigation. This study presents a novel framework for developing carbon‐neutral visions for cities and communities. We established five “principles,” investigated options encompassing four parameters (management, goal setting, actions, and quantification),

Optimizing Eco‐Industrial Park Site Selection for Circular Supply Chains: A Novel Hybrid Decision‐Making Approach

open access: yesSustainable Development, EarlyView.
ABSTRACT Eco‐Industrial Parks (EIPs) are critical infrastructure for transitioning to sustainable production and consumption patterns, enabling resource efficiency through industrial symbiosis. However, the success of these circular ecosystems depends heavily on strategic location planning that balances conflicting economic, environmental, and social ...

Road Traffic Noise: Losing the Fight?

open access: yes, 2004
In 1986, the OECD produced “Fighting Noise: Strengthening Noise Abatement Policies” [1] and, less than a decade later, “Fighting Noise in the 1990s ” [2].
