Increasing energy demands, depletion of fossil fuels, and environmental issues have impelled society to choose the pathways renewable clean energy, which motivated scientists engineers develop sustainable, renewable, resources. However, major challenge is implementation low-cost, flexible approaches materials fulfill requirements storage conversion technologies, specifically those involving bat...

Optimizing the ionomer/carbon (I/C) ratio in catalyst layer (CL) of polymer electrolyte membrane fuel cells (PEMFCs) is vital for maximizing PEMFC efficiency. In this study, effect I/C a platinum (Pt) loaded on polybenzimidazole (PBI)-coated Vulcan (Vulcan/PBI/Pt) compared with conventional Pt (Vulcan/Pt). Furthermore, study determines that CL comprising Vulcan/PBI/Pt an = 0.2 exhibits highest ...

The separated electromagnetic responses RL(q, ω) and RT (q, ω) for inclusive electron scattering off nuclei are studied within a functional scheme.

Fatigue assessment of welded joints is vital for accurately designing and predicting lifetime many engineering structures. Assessing weld fatigue challenging due to the high variability in quality geometry because volatile nature joining method further challenges arise when assessing multiaxial fatigue. In this paper, two approaches, Findley criterion Modified Wöhler Curve Method, on several ex...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

We present a set of problem frames specialized to the area of geographic applications. Problem frames describe the elements of common problems, and help a specifier understand and decompose a complex problem into simpler subproblems for which a solution is often known. We provide an overview of the main issues in geographic applications, and present twelve frames that address many of the proble...
