In security games, a defender commits to a mixed strategy for protecting a set of n targets of values αi; an attacker, knowing the defender’s strategy, chooses which target to attack and for how long. We study a natural version in which the attacker’s utility grows linearly with the time he spends at the target, but drops to 0 if he is caught. The defender’s goal is to minimize the attacker’s u...

It is well known that the category KHaus of compact Hausdorff spaces is dually equivalent to the category KRFrm of compact regular frames. By de Vries duality, KHaus is also dually equivalent to the category DeV of de Vries algebras, and so DeV is equivalent to KRFrm, where the latter equivalence can be described constructively through Booleanization. Our purpose here is to lift this circle of ...

Individuals eligible in both Medicaid and Medicare, the dually eligible enrollees, account for a disproportionate share of Medicaid utilization and payments. While comprising 14.7 percent of the Medicaid population, they accounted for 40.5 percent of Medicaid payments in 2002. Mean reimbursement for the dually eligible enrollees was nearly four times that of non-dually eligible Medicaid enrolle...

in this paper we have generalized the concepts of ,q-fuzzy ideals, ,q-fuzzy quasi-ideals and,q-fuzzy bi-ideals by introducing the concepts of   k ,q -fuzzy ideals,   k ,q -fuzzy quasiideals and   k ,q -fuzzy bi-ideals in ternary semigroups and several related properties are investigated. different characterizations of regular and weakly regular ternary semigroups b...

Setting of this research is Bishop’s constructive mathematics, the mathematics developed on Intuitionistic logic. If (X, =, 6=, θ) is an anti-ordered set, for a coequality q on X we say that it is strongly regular if it is regular and θ ◦ q ⊆ q ◦ θ holds. In this case, θ ◦ q is a quasi-antiorder relation on X such that the relation Θ = π ◦ θ ◦ π−1 on X/q is the maximal anti-order on X/q.

| This paper presents a quasi-interpolation method for DIV-CURL vector splines in two dimensions on both innnite and nite domains. The quasi-interpolant is a linear combination of translates of dilates of a basis function. In particular, our discussion focuses on the approximation of a vector-valued function deened on a nite domain for practical application purposes. In such a case, edge functi...
