AN APPROACH FOR SIMULTANEOUSLY DETERMINING THE
OPTIMAL TRAJECTORY AND CONTROL OF A VIBRATING
SHELL
In this article, for a twodimensional wave control system, we are going
to present a new combinational solution path. First, by considering all necessary
conditions, the problem is represented in a variational format in which the trajectory
is shown by a trigonometric series with the unknown coefficients.

ON (1,2)* 
rw
 CLOSED SETS AND (1,2)*
rw
OPEN SETS
The aim of this paper is to introduce the concept of (1,2)*rwclosed
sets in bitopological spaces and study some of its properties. Their corresponding
(1,2)*rwopen sets are also defined and studied in this paper.

CERTAIN CLASSES OF UNIVALENT FUNCTIONS HAVING
NEGATIVE COEFFICIENTS
Eight classes of univalent analytic functions with negative coefficients,
involving Ruscheweyh derivative and a linear operator, have been studied in regard
to coefficient inequality, distortion theorems, extreme points, radii of starlikeness
and convexity.

ON SOME NEW INEQUALITIES RELATED TO FEJ´ER’S
INEQUALITY FOR SUPERQUADRATIC FUNCTIONS
In this paper some new inequalities related to Fej´er’s inequality and
Hermite  Hadamard’s inequality for superquadratic functions are established. We
also get refinements of some known results established in [20] when superquadratic
function is nonnegative and hence convex.

AN UPPER BOUND FOR THE RAMSEY NUMBER R(C6, K9)
Let C_{m} denote a cycle of length
m and K_{n} a complete graph of order n. In
this paper we establish an upper bound for the Ramsey number of r(C_{6},K_{9}) by proving
that 41 £
