Let $G$ be a monoid with identity $e$. In this paper, first we introduce the notions of $G$-graded hyperrings, graded hyperideals and graded hyperfields in the sense of Krasner hyperring $R$. Also, we define the notion of a greded $R$-hypermodules and some examples are presented. Then we investigate graded maximal, graded prime and graded primary hyperideals of a graded hyperring $R$. Finally, ...

Real-time monitoring during soil compaction can be made possible by utilizing the vibration signature of a vibratory roller compactor. The compactor and soil constitute a coupled dynamic system, albeit complex and nonlinear. As the soil density increases and its mechanical properties change, the dynamic response of the compactor will change. Developing a thorough knowledge of the relationship b...

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Soiling losses on high concentrating photovoltaic (HCPV) systems may be influenced by the spectral properties of accumulated soil. We have predicted the response of an isotype cell to changes in spectral content and reduction in transmission due to soiling using measured UV/vis transmittance through soil films. Artificial soil test blends deposited on glass coupons were used to supply the trans...

Decomposing plastics, including plastic bottles, is a very difficult process because it takes 50-100 years. Every year, the use of bottles increasing, but only few people are willing to treat bottle waste. In this study, waste used as substitute fine aggregate and shaped in such way have sand-like gradation. The variations graded 0%, 5%, 10%, 12%. test objects for each variation consist three s...

We prove uniform convexity of solutions to the capillarity boundary value problem for fixed boundary angle in (0, π/2) and strictly positive capillarity constant provided that the base domain Ω ⊂ R is sufficiently close to a disk in a suitable C-sense.

The squamate fauna of the fossil dunes of the middle Rio São Francisco in the Brazilian semiarid Caatingas, State of Bahia, is characterized by high richness and endemism. An important part of squamates from the area was described in the last few years, including new genera, some showing unsuspected morphological adaptations for life on sand in Abstract Herpetofauna of the Quaternary sand dunes...

We introduce a Halpern-type iteration for a generalized mixed equilibrium problem in uniformly smooth and uniformly convex Banach spaces. Strong convergence theorems are also established in this paper. As applications, we apply our main result to mixed equilibrium, generalized equilibrium, and mixed variational inequality problems in Banach spaces. Finally, examples and numerical results are al...

We introduce an iterative procedure for finding a point in the zero set (a solution to 0 ∈ A(v) and v ∈ C) of an inverse-monotone or inverse strongly-monotone operator A on a nonempty closed convex subset C in a uniformly smooth and uniformly convex Banach space. We establish weak convergence results under suitable assumptions.

We introduce hybrid-iterative schemes for solving a system of the zero-finding problems of maximal monotone operators, the equilibrium problem, and the fixed point problem of weak relatively nonexpansive mappings. We then prove, in a uniformly smooth and uniformly convex Banach space, strong convergence theorems by using a shrinking projection method. We finally apply the obtained results to a ...
