**ABSTRACT:**In this paper, the second order differential equation with a state derivative dependent delay of the form $a_2x"(z) + a_1x'(z) + a_0x(z) = x(p(z) + bx'(z)) + h(z)$ has been studied. Considering a convergent power series $g(z)$ of an auxiliary equation $a_2 \gamma^{2} g"(\gamma z) g'(z) = [g (\gamma^2 z) - p(g(\gamma z))] \gamma g'(\gamma z)(g' (z))^{2} + bh'(g(z))(g' (z))^{3} + \Big( a_2p"(g(z))+ a_1p'(g(z)) +a_0p(g(z))\Big) (g'(z))^{3} - a_1\gamma g'(\gamma z) (g' (z))^{2} - a_0g(\gamma z)(g'(z))^{3} + a_2\gamma g'(\gamma z)g"( z)$ with the relation $p(z) + bx'(z) = g(\gamma g^{-1}(z)),$ we obtain an analytic solution $x(z).$ Moreover, an analytic solution depends on a parameter $\gamma$ which satisfies one of the following conditions: $(H1) \ 0<|\gamma|<1,$ $(H2) \ \gamma = e^{2\pi i \theta }$ where $\theta$ is a Brjuno number or $(H3) \ \gamma = e^{2\pi i \theta }$ where $\theta$ is a rational number.International Journal of Mathematics and Mathematical Sciences 08/2015; 2015(4).

##### Article: Vehicle Routing Problem for Multiple Product Types, Compartments, and Trips with Soft Time Windows

[Show abstract] [Hide abstract]

**ABSTRACT:**This paper presents a mathematical model to solve the vehicle routing problem with soft time windows (VRPSTW) and distribution of products with multiple categories. In addition, we include multiple compartments and trips. Each compartment is dedicated to a single type of product. Each vehicle is allowed to have more than one trip, as long as it corresponds to the maximum distance allowed in a workday. Numerical results show the effectiveness of our model.International Journal of Mathematics and Mathematical Sciences 01/2015; 2015(1):1-9. DOI:10.1155/2015/126754 - [Show abstract] [Hide abstract]

**ABSTRACT:**We have proved here that the expected number of real zeros of a random hyperbolic polynomial of the form y = P n t = n 1 a 1 cosh t + n 2 a 2 cosh 2 t + ⋯ + n n a n cosh n t , where a 1 , … , a n is a sequence of standard Gaussian random variables, is n / 2 + o p ( 1 ) . It is shown that the asymptotic value of expected number of times the polynomial crosses the level y = K is also n / 2 as long as K does not exceed 2 n e μ ( n ) , where μ ( n ) = o ( n ) . The number of oscillations of P n ( t ) about y = K will be less than n / 2 asymptotically only if K = 2 n e μ ( n ) , where μ ( n ) = O ( n ) or n - 1 μ ( n ) → ∞ . In the former case the number of oscillations continues to be a fraction of n and decreases with the increase in value of μ ( n ) . In the latter case, the number of oscillations reduces to o p ( n ) and almost no trace of the curve is expected to be present above the level y = K if μ ( n ) / ( n log n ) → ∞ .International Journal of Mathematics and Mathematical Sciences 01/2015; 2015(5):1-7.

**ABSTRACT:**Let N be a near ring. An additive mapping F : N → N is said to be a generalized semiderivation on N if there exists a semiderivation d : N → N associated with a function g : N → N such that F ( x y ) = F ( x ) y + g ( x ) d ( y ) = d ( x ) g ( y ) + x F ( y ) and F ( g ( x ) ) = g ( F ( x ) ) for all x , y ∈ N . In this paper we prove that prime near rings satisfying identities involving semiderivations are commutative rings, thereby extending some known results on derivations, semiderivations, and generalized derivations. We also prove that there exist no nontrivial generalized semiderivations which act as a homomorphism or as an antihomomorphism on a 3-prime near ring N .International Journal of Mathematics and Mathematical Sciences 01/2015; 2015(3):1-7.
