Abstract: The combination of a manpower supply model and objective programming with preemptive needs gives a helpful instrument to adding to a future year labor arrange under clashing Socio-economic-authoritative goals. Effective usage obliges a nearby administration inclusion in altering probabilities and indicating objectives, needs and looming approach changes. Such a methodology is exhibited in this paper and is kept straightforward, yet point by point and brought together, with the goal that it is effectively seen by specialists and understudies of operational examination/administration science.

Abstract: In this paper we define the weighted Cesaro sequence spaces ces (p, q).We prove the space ces (p, q) is a complete paranorm space. In section-2 we determine its Kothe-Toeplitz dual and continuous dual. In section-3 we establish necessary and sufficient condition for a matrix A to map ces (p, q) to l_∞ and ces (p, q) to c, where l_∞ is the space of all bounded sequences and c is the space of all convergent sequences. We also get some known and unknown interesting results as corollaries.

Abstract: Dubins has proved in 1957 that the minimum length path between an initial and a terminal configuration can be found among the six paths {LSL, RSR, LSR, RSL, RLR, LRL}. Skel and Lumelsky have studied the length of Dubins path with the initial configuration (0, 0; α) and the terminal configuration (d, 0; β) and the minimal turning radius ρ=1 in 2001. We extended the Skel and Lumelsky’s results to the case that the initial and terminal configuration is(x0, y0, α), (x1, y1, β), respectively (where x0, y0, x1, y1ϵℝ), and the minimal turning radius is ρ>0.

Abstract: Following the approach of Gregori and Sapena, in this paper we introduced a new class of contractions and we establish some common fixed point theorems in G-complete fuzzy metric. Also a theorem on the equivalency related to completeness is given. The results are a genuine generalization of the corresponding results of Gregori and Sapena.

Abstract: In the present paper, we find out the eigenvalues and the corresponding eigenfunctions of the modified Frankl problem with a nonlocal parity condition, the completeness and the basis property in the elliptic part of the third kind of a domain in L2(0, π/2). We also consider a new boundaries condition and analyze the orthogonal basis of the eigenfunctions depending on parameters of the problem.

Abstract: In this paper, a combined form of the Laplace transforms method with the homotopy perturbation method is proposed to solve Korteweg-DeVries (KDV) Equation. This method is called the homotopy perturbation transform method (HPTM). The (HPTM) finds the solution without any discretization or restrictive assumptions and avoids the round-off errors. The results reveal that the proposed method is very efficient, simple and can be applied to other nonlinear problems.

Abstract: Global fifth degree polynomial spline is developed. Ideas applied in the field of high order WENO (Weighted Essentially non Oscillating) methods for numerical solving compressible flow equations are used to construct interpolation which has accuracy closed to accuracy of classical cubic spline for smooth interpolated functions, and which reduces undesirable oscillations often appearing in the case of data with break points. Fifth degree polynomial spline is constructed in two steps. Third degree spline is developed in first step by usage of additional stencils above three point central stencil, dealt in classical cubic splines. The Procedure of weights calculation provides choice of preferable stencils. Compensating terms are introduced to left side of governing equations for calculation of spline derivative knot values. This spline may be identical to classical cubic spline for “good” data. Damping of oscillations is achieved at the cost of reducing smoothness till C1. To restore C2 smoothness fifth degree terms are added to third degree polynomials in second step. These terms are chosen to provide continuity of the spline second derivative. Fifth degree polynomial spline is observed to produce lesser oscillations, then classical cubic spline applied to data with break points. These splines have nearly the same accuracy for smooth interpolated functions and sufficiently large knot numbers.
