Abstract :Presently angular measurements are made using protractors having a normal accuracy of 1 or at the most ½ . The scale of chords, as linear scale, can be constructed for measurement and construction of angles having accuracy equal to that of a normal protractor. This paper presents a new concept of construction of a diagonal scale of chords that can have an accuracy of 10 or less, and thus, using diagonal scale of chords, angles can be constructed or measured to a higher accuracy which is not possible using normal size protractors.
Keywords - Angle measurements, Protractor, Scale of chords, Diagonal scale of chords

Abstract :Let G = (V, E) be a simple graph. A set S  V is a dominating set of G, if every vertex in V-S is adjacent to atleast one vertex in S. Let 2 n C be the square of the Cycle n C and let 2 ( , ) n D C i denote the family of all dominating sets of 2 n C with cardinality i. Let 2 ( , ) n d C i = | 2 ( , ) n D C i |. In this paper, we obtain a recursive formula for 2 ( , ) n d C i . Using this recursive formula, we construct the polynomial, 2 ( , ) n D C x = 2 5 ( , ) n i n i n   d C i x      , which we call domination polynomial of 2 n C and obtain some properties of this polynomial.

Abstract: This paper is concerned with the determination of the distribution of temperature and displacement in a thin semi-infinite elastic rod when its free end is subjected to periodic heating. It has been pointed out by P.Chadwick(1960) that the rigorous approach,i.c. the approach by way of the coupled equations, to the thermal boundary value problem. In this paper the one dimensional problem of the periodic heating of the free surface of a semi-infinite rod has been solved by a perturbation procedure, approximations upto the first order being retained.

Abstract :In this paper we prove two fixed point theorems in topological vector space valued cone metric spaces (briefly TVS-CMS). To that end we introduce the concept of complete topological algebra cone (briefly CTA cone). Our theorems are generalizations of corresponding theorems in [8] and [13]. The paper also gives answers to the open problems posed in [15]. Finally we give an application of our first theorem. AMS Mathematics Subject Classification (2010): 47H10, 54H25, 46A40
