Enhancements of Wave Power Absorption with Arrays and a Vertical Breakwater

open access: yesJournal of Marine Science and Engineering
The capability of the in-house transient wave-multibody computational tool, ITU-WAVE, is extended to predict the wave power absorption with Wave Energy Converters (WECs) arrays placed in front of a vertical breakwater.

Understanding the Link Between Policy Design and Distributional Impacts of Local Wind Energy Ordinances

open access: yesReview of Policy Research, Volume 43, Issue 3, May 2026.
ABSTRACT Zoning is one of the most widely used land use regulations in the U.S. An increasing number of local governments have adopted zoning ordinances to regulate renewable energy projects. However, there has been very limited research on the impact of this local regulatory tool.

Techno-Economic Development of WECs [PDF]

open access: yes, 2016
The successful development process of WECs demands large amounts of time and means. The optimal development trajectory manages to keep these expenses to a minimum while delivering an economically viable product at the end of its development. As related expenses (time and money) increase exponentially with the development stages (TRLs) while flexible ...

A New Padé Approach to Modeling Wormholes in Dekel‐Zhao Dark Matter Halos

open access: yesAnnalen der Physik, Volume 538, Issue 3, March 2026.
A matter‐first Padé strategy is introduced to build traversable wormholes from prescribed dark‐matter halos. Rational Padé fits approximately the Dekel–Zhao density and are analytically integrated to obtain a shape function that exactly reproduces the intended matter content, avoiding spurious poles of geometry‐first schemes.
