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 ...

Blind Equalisation and Carrier Offset Compensation for Bluetooth Signals [PDF]

open access: yes, 2004
Bluetooth systems operating in medium to large sized rooms can suffer multipath distortion, which may be compounded by presence of frequency offsets permitted by the Bluetooth standard.

Possible impact of construction activities around a permanent GNSS station – A time series analysis

open access: yesJournal of Geodetic Science
In this article, we address the potential effects of construction activities around a permanent Global Navigation Satellite System (GNSS) station. The study is based on a consistent time series of GNSS observations collected over a span of almost 13 ...

Multipath parsing in the brain

open access: yesProceedings of the 62nd Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers)
Humans understand sentences word-by-word, in the order that they hear them. This incrementality entails resolving temporary ambiguities about syntactic relationships. We investigate how humans process these syntactic ambiguities by correlating predictions from incremental generative dependency parsers with timecourse data from people undergoing ...

Moderate is the New Black: Shifts and Intersections in Saudi Arabia's Domestic and Foreign Policy

open access: yesGlobal Policy, EarlyView.
ABSTRACT The Kingdom of Saudi Arabia (KSA) is undergoing a period of intense changes. Its current stage of transformation has been led by Prince Mohammed bin Salman (MbS) since 2015, seeking to turn the Kingdom into a story of successful governance and one of the leading powers in the Middle East. In hardly understood yet very consequential ways, KSA's

WAH‐i: Optimising microphone array geometry for customised localisation accuracy

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

The Evolution of Breast Cancer Detection: A Review of Imaging, Machine Learning, and Multimodal Strategies

open access: yesComputational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Breast cancer is still a serious problem in the world arena, where its early and prompt detection is the most important factor in improving patient prognosis and survival. The use of traditional diagnostic techniques, such as imaging (e.g., mammography and ultrasound) and subsequent histopathological examination, is the mainstay, which ...

Reverse-Link Performance of Synchronous DS-CDMA Systems in Dispersive Rician Multipath Fading Channels

open access: yes, 2003
The reverse-link performance of synchronous DS-CDMA is investigated in Rician multipath fading environments. The numerical results show that the performance benefits of synchronous transmission depend on the specular path’s power as well as on the ...
