In combination with simultaneous approximation terms, summation-by-parts (SBP) operators provide a flexible and efficient methodology that leads to consistent, conservative, and provably stable high-order discretizations. Traditional diagonal-norm SBP operators with a repeating interior point operator lead to solutions that have a global order of accuracy lower than the order of the interior po...

The rapid growth of the automotive industry has placed a significant demand on earth resources such as metal and minerals. This led to shortage materials an increase in material prices. One solutions enhance resource management is perform parts remanufacturing during product design ease part classification. However, this initiative not yet widely explored, particularly terms guideline or tool d...

In this manuscript, we study the inverse problem for non self-adjoint Sturm--Liouville operator $-D^2+q$ with eigenparameter dependent boundary and discontinuity conditions inside a finite closed interval. By defining  a new Hilbert space and  using its spectral data of a kind, it is shown that the potential function can be uniquely determined by part of a set of values of eigenfunctions at som...

in this study biostratigraphy of the upper cretaceous deposits (gurpi formation) in sepidan section located in the interior fars basin (sw iran) was studied. the gurpi formation in this section consists of 360 m lime shale, argillaceous limestone and shale laid continuously on the ilam formation and with a paraconformity under the pabdeh formation. nine genera and 27 species of planktonic foram...

we study interior operators and interior structures in a fuzzy setting.we investigate systems of “almost open” fuzzy sets and the relationshipsto fuzzy interior operators and fuzzy interior systems.
