In this paper, the Quaternary Continuous Classical Optimal Control Problem (QCCOCP) for the Quaternary Linear Elliptic Partial Differential Equations (QLEPDEqs) is studied. The mathematical model for the proposed problem is formulated, and it consists of the QLEPDEqs, the Objective Function (OF), and the set of state controls. The method of Galerkin (MG) is used to prove the existence theorem of a unique state vector solution (QSVS) of the Weak Form (WF) for the QLEPDEqs when the Quaternary Classical Continuous Control Vector (QCCCV) is fixed. Furthermore, the existence of a Quaternary Classical Continuous Optimal Control Vector (QCCOCV) ruled by the QLEPDEqs is stated and proved. The Quaternary Adjoint Equations (QAJEqs) associated with
... Show MoreTomato (Lycopersicon esculentum Mill) and cucumber (Cucumis sativus L.) seeds were imbided with water at 10°c or 4°c for 4, 8, and 16 hours before planting to study germination rate, mean germination time, and final germination percentage as well as electrolyte leakage from chilled seeds. Seeds imbided more water at 10°c compared to that at 4°c. Coefficient velocity of germination and final percent of germination decreased with the decrease of temperature and increasing time of imbibition. Germination percent under laboratory conditions was higher than that under field conditions. Also, it was found that tomato seeds were more sensitive to chilling imbibition. Electrolyte leakage increased as temperature of imbib

This paper aims to study the quaternary classical continuous optimal control problem consisting of the quaternary nonlinear parabolic boundary value problem, the cost function, and the equality and inequality constraints on the state and the control. Under appropriate hypotheses, it is demonstrated that the quaternary classical continuous optimal control ruling by the quaternary nonlinear parabolic boundary value problem has a quaternary classical continuous optimal control vector that satisfies the equality constraint and inequality state and control constraint. Moreover, mathematical formulation of the quaternary adjoint equations related to the quaternary state equations is discovered, and then the weak form of the quaternary adjoint

This article introduces the notion of restriction of a non-empty class of subset of the power set on a nonempty subset of a universal set.

In addition, it has been shown that the restriction of the P*–field is not necessarily contained in the P*–field, and the converse is true. We provide a necessary condition for the P*–field to obtain th

The depth of possible damage to the surface of copper and titanium as well as depth of the crater to both materials were considered in this study. The study revealed that linear model is only possible when estimating depth of possible damage for copper material, this means that the depth of possible damage increases with the increment of number of laser pulses .As for titanium material, it is found the relationship is nonlinear. The depth of possible damage of titanium and copper is not the same, and copper seems to be more predictable than titanium.
