Investigating the Performance of EKF, UKF, and PF for Quadrotor Position Estimation in Hurricane Wind Disturbances Open
Natural disasters, such as hurricanes and typhoons, pose significant challenges to public safety and infrastructure. While government agencies rely on multi million dollar UAV systems for storm data collection and disaster response, smalle…
Optimizing the precision of infrared measurements using the Eppley Laboratory, Inc. model PIR pyrgeometer Open
The Eppley Model PIR is widely used for thermal infrared wavelength (3.5–50 μm) measurements of the downwelling and upwelling radiation from the atmosphere and surface, respectively. The field of view of the instrument is 2π steradians wit…

On the Relationships between Clear-Sky Indices in Photosynthetically Active Radiation and Broadband Ranges in Overcast and Broken-Cloud Conditions Open
Several studies proposed relationships linking irradiances in the photosynthetically active radiation (PAR) range and broadband irradiances. A previous study published in 2024 by the same authors proposes a linear model relating clear-sky …

Introduction Open
—J. Blunden and T. Boyer In 2023, La Niña conditions that generally prevailed in the eastern Pacific Ocean from mid-2020 into early 2023 gave way to a strong El Niño by October. Atmospheric concentrations of Earth’s major greenhouse gases—…

Ocean surface radiation measurement best practices Open
Ocean surface radiation measurement best practices have been developed as a first step to support the interoperability of radiation measurements across multiple ocean platforms and between land and ocean networks. This document describes t…

Evidence of linear relationships between clear‑sky indices in photosynthetically active radiation and broadband ranges Open
This study provides empirical relationships between photosynthetically active radiation (PAR) and broadband clear‑sky indices at ground level for both the PAR global irradiance and its direct component. Once multiplied by the irradiance in…

Introduction Open
—J. BLUNDEN, T. BOYER, AND E. BARTOW-GILLIES Earth’s global climate system is vast, complex, and intricately interrelated. Many areas are influenced by global-scale phenomena, including the “triple dip” La Niña conditions that prevailed in…

Algorithmic Foundations of Inexact Computing Open
Inexact computing also referred to as approximate computing is a style of designing algorithms and computing systems wherein the accuracy of correctness of algorithms executing on them is deliberately traded for significant resource saving…
Contributors to multidecadal dimming and brightening of surface solar radiation over Northern Hemisphere continents Open
Multidecadal dimming and brightening of solar radiation at Earth’s surface has been shown to occur over all continents. Trends have been especially well documented over the Northern Hemisphere (NH) with dimming from the 1950s through…

Recurrent Problems in the LOCAL model Open
The paper considers the SUPPORTED model of distributed computing introduced by Schmid and Suomela [HotSDN'13], generalizing the LOCAL and CONGEST models. In this framework, multiple instances of the same problem, differing from each other …
Byzantine Spectral Ranking Open
We study the problem of rank aggregation where the goal is to obtain a global ranking by aggregating pair-wise comparisons of voters over a set of items. We consider an adversarial setting where the voters are partitioned into two sets. Th…

Forcing for Multidecadal Surface Solar Radiation Trends Over Northern Hemisphere Continents Open
The long‐term variation of North Pacific and North Atlantic sea surface temperatures (SSTs) is shown to be associated with multidecadal trends of surface solar radiation in North America, Europe, and Asia. Long‐term, large‐scale warm SST a…

Awake Complexity of Distributed Minimum Spanning Tree Open
We study the distributed minimum spanning tree (MST) problem, a fundamental problem in distributed computing. It is well-known that distributed MST can be solved in $\tilde{O}(D+\sqrt{n})$ rounds in the standard CONGEST model (where $n$ is…
Guarding Polygons with Holes Open
We study the Cooperative Guarding problem for polygons with holes in a mobile multi-agents setting. Given a set of agents, initially deployed at a point in a polygon with $n$ vertices and $h$ holes, we require the agents to collaboratively…
Comparison of clinical outcomes of Endoscopic vs Microscopic lumbar discectomy: A prospective randomized controlled study Open
To compare clinical and functional outcomes of Endoscopic and Microscopic lumbar discectomy in patients with L3-L4, L4-L5, L5-S1 intervertebral disc prolapse. 50 patients planned for surgical discectomy, were randomized by selecting every …
