Abstract: In this paper , we have devoted our attention to the development of block cipher , which involves a key bunch matrix , an additional matrix , and key matrix utilized in the development of a pair of functions called permute and substitute , over a finite extension field of F2 . The entries of the matrices are polynomials over F2, this create confusion and diffusion for each round of the iteration process of the encryption algorithm. The security of this process depends upon the size of the extension field. This cipher cannot be broken by any cryptanalytic attack generally available in the literature of cryptography.

Key words: Function field, Key bunch matrix, Permute, Primitive polynomial, Substitute.

Abstract: In this research paper ,two right angled triangle relation explained with the help of formulas. This relation explained in two part i.e. Area relation and Sidemeasurement relation.Right angled triangle can be narrowed in segment and as like right angled triangle called Seg right angled triangle.Seg right angled triangle always become in zero area. Very feamas pyathagoras theoram proof with the help of Relation All Mathematics methode. also we are given proof of DGP theorem i.e. "In a right angled triangle ,the square of hypoténuse is equal to the subtract of the square of the sidemeasurement and four times the area". We are trying to give a new concept "Relation All Mathematics" to the world .I am sure that this concept will be helpful in Agricultural, Engineering, Mathematical world etc.

Abstract: We know that the smallest positive integer f such that af 1 mod m is called the exponent of 'a' modulo m and is denoted by expma. We say that 'a' is a semi-primitive root mod m if expma = 2  (m) . We proved that there exists a semi-primitive root for mod m when m = p, 2 p(for2), 22.p and 2if 3. Also it was established that there exists a semi-primitive root for mod m when m = p1p2 where p1 and p2 are distinct odd primes and at least one prime is of the form 4n+3.In this paper we discuss the existence of semi primitive root mod pαwhenever it exists for mod p. we have If 'a'

Abstract: Fisher (1925), in his famous paper, gave a method of constructing an efficient estimator by using a successive approximation. If there exists a root-n consistent estimator of the parameter and if the probability density function satisfies certain regularities conditions, it is possible to construct an efficient estimator of the parameter. This can be done by a single approximation ( Lehman and Casella, 1998). In order to distinguish between the efficient estimators, Rao( (1961, 1963) introduced the concept of second order efficiency (s.o.e.) of an estimators. In this note, we consider the estimator obtained by using two iterations in the approximation and obtain its s.o.e. following the definition of Rao. It follows from this derivation that we can construct a second order efficient estimator, if it exists, by using any root-n consistent estimator of the parameter.

Keywords: and phrases: First order efficient estimator, maximum likelihood estimator, root-n consistent estimator, second order efficiency.

Abstract: In this paper, we study a class of (, ) -Finsler metrics called Binomial (, ) -metrics on an n -dimensional differential manifold M and get the conditions for such metrics to be Berwald, Douglas and Projectively flat. Further, we prove that a Binomial (, ) -metric is of scalar flag curvature and isotropic S -curvature if and only if it is isotropic Berwald metric with almost isotropic flag curvature. 2010 Mathematics Subject Classifications: 53B40, 53C60.

Abstract: In order to look into the transient behavior of vibrating systems, the Krylov-Bogoliubov-Mitropolskii (KBM) method is extensively used. The method was initially devised to obtain the periodic solutions of second order nonlinear differential systems with small nonlinearities. In this article, the method has been modified to investigate the solutions of fifth order more critically damped nonlinear systems. A fifth order more critically damped nonlinear differential system is considered and asymptotic solutions are studied when the triply eigenvalues are small and the other two equal eigenvalues are large. The results obtained by the presented modified KBM method agree with those obtained by the fourth order Runge-Kuttamethod satisfactorily.
Keywords: KBM, nonlinearity, more critically damped system, asymptotic solution, eigenvalues

Abstract: Graph Theory is the fast growing area of research in Mathematics. The concepts of Number Theory, particularly, the "Theory of Congruence" in Graph Theory, introduced by Nathanson[8], paved the way for the emergence of a new class of graphs, namely, "Arithmetic Graphs". Cayley graphs are another class of graphs associated with the elements of a group. If this group is associated with some arithmetic function then the Cayley graph becomes an Arithmetic graph. The Cayley graph associated with Euler Totient function is called an Euler Totient Cayley graph and in this paper we study the Basic Minimal Domination Functions of Euler Totient Cayley graphs.

Keywords: Euler Totient Cayley Graph, Minimal Dominating Functions, Basic Minimal Dominating Functions.

Abstract: The design of special double sampling plan is proposed for the truncated life tests assuming that the lifetime of a product follows generalized log-logistic distribution . The minimum sample sizes of the special double sampling plan are determined to ensure that the median life is longer than the given life at the specified consumer's confidence level. The operating characteristic values are analysed.The minimum median ratios are obtained so as to meet the producer's risk at the specified consumer's confidence level. Numerical illustrations are provided to explain the use of constructed tables. The efficiency of special double sampling plan is analysed with single sampling plan.
