Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

open access: yesAdvanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

The no-boundary measure in string theory: Applications to moduli stabilization, flux compactification, and cosmic landscape

open access: yes, 2012
We investigate the no-boundary measure in the context of moduli stabilization. To this end, we first show that for exponential potentials, there are no classical histories once the slope exceeds a critical value.

Characterizing urban landscapes using fuzzy sets [PDF]

open access: yes, 2016
Characterizing urban landscapes is important given the present and future projections of global population that favor urban growth. The definition of “urban” on a thematic map has proven to be problematic since urban areas are heterogeneous in terms of ...

Perceptual Dominant Color Extraction by Multidimensional Particle Swarm Optimization

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
Color is the major source of information widely used in image analysis and content-based retrieval. Extracting dominant colors that are prominent in a visual scenery is of utmost importance since the human visual system primarily uses them for perception

Stability of Organic Photovoltaics: From Root Causes to Advanced Analytical Techniques

open access: yesAdvanced Energy Materials, EarlyView.
This review explains the causes and mechanisms of degradation in organic photovoltaics (OPVs). It explores how various factors, including heat, light, oxygen, and inherent material properties, influence OPV stability. The study categorizes degradation pathways and analyzes their impact on device performance, providing insights into the fundamental ...

Fuzzy Subordination Results for Meromorphic Functions Associated with Hurwitz–Lerch Zeta Function

open access: yesMathematics
The notion of the fuzzy set was incorporated into geometric function theory in recent years, leading to the emergence of fuzzy differential subordination theory, which is a generalization of the classical differential subordination notion.

Non-dominated Solution of Fuzzy Maximum-Return Problem [PDF]

open access: yesThe Journal of Fuzzy Mathematics Vol. 26, No. 1, 2018, Los Angeles, 2016
In this paper, we find a non-dominated solution of a fuzzy maximum-return problem ( unconstrained single-variable fuzzy optimization problem ) . We establish Newton method to find the solution of the unconstrained single-variable fuzzy optimization problem using the differentiability of $\alpha$-level functions of a fuzzy-valued function and partial ...

Performance Rate Analysis in Photovoltaic Solar Plants by Machine Learning

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Thermal imaging and deep learning are combined to detect faults in photovoltaic panels inspected by autonomous vehicles. A robust pipeline classifies panel defects from aerial thermograms using a convolutional neural network, supporting both real‐time and offline analysis.
