Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Modeling Tidal Datums and Spatially Varying Uncertainty in the Texas and Western Louisiana Coastal Waters

open access: yesJournal of Marine Science and Engineering, 2019
Tidal datums are key components in NOAA’s Vertical Datum transformation project (VDatum), which enables effective vertical transformation of the water level between tidal, orthometric, and ellipsoid -based three-dimensional reference systems.

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

open access: yessteel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

How Significant is the Dynamic Component of the North American Vertical Datum?

open access: yesJournal of Geodetic Science, 2012
One of the main current geodetic activities in North America is the definition and establishment of a geoid-based vertical datum that will replace the official CGVD28 and NAVD88 datums in Canada and the USA, respectively.

Evaluation of Moisture Ageing Status of Cross‐Linked Polyethylene Insulation in Power Cables at Different Temperatures

open access: yesHigh Voltage, EarlyView.
ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...

Formal Safety and Security Assessment of an Avionic Architecture with Alloy

open access: yes, 2014
We propose an approach based on Alloy to formally model and assess a system architecture with respect to safety and security requirements. We illustrate this approach by considering as a case study an avionic system developed by Thales, which provides ...

Tropical Fukaya Algebras

open access: yes, 2020
We introduce a tropical version of the Fukaya algebra of a Lagrangian submanifold and use it to show that tropical Lagrangian tori are weakly unobstructed.

Land Use and Economic Trade‐Offs of Large‐Scale Solar in Agricultural Regions: Marginal National Impacts, Significant Regional Variations

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Large‐scale solar generation is critical for energy transitions. In Australia, increased solar production to meet emission targets means its land footprint increasingly competes with agricultural land. Understanding the scale and location of agricultural land use change and potential profitability losses from large‐scale solar farms is ...

Converting NAD83 GPS heights into NAVD88 elevations with LVGEOID, a hybrid geoid height model for the Long Valley volcanic region, California [PDF]

open access: yes, 2008
A GPS survey of leveling benchmarks done in Long Valley Caldera in 1999 showed that the application of the National Geodetic Survey (NGS) geoid model GEOID99 to tie GPS heights to historical leveling measurements would significantly underestimate the
