Exact solutions for some unsteady flows of generalized second grade fluids in cylindrical domains

JPRM-Vol. 1 (2008), Issue 1, pp. 171 – 180 Open Access Full-Text PDF

Abstract: The velocity field and the adequate shear stress, corresponding to the unsteady flow of generalized second grade fluids due to a constantly accelerating circular cylinder, are determined by means of the Hankel and Laplace transforms. The solutions that have been obtained satisfy all imposed initial and boundary conditions and for \(β → 1\) reduce to the similar solutions for the second grade fluids performing the same motion.

A greedy approach for computing longest common subsequences

JPRM-Vol. 1 (2008), Issue 1, pp. 165 – 170 Open Access Full-Text PDF
Afroza Begum
Abstract: This paper presents an algorithm for computing Longest Common Subsequences for two sequences. Given two strings \(X\) and \(Y\) of length \(m\) and \(n\), we present a greedy algorithm, which requires \(O(n log s)\) preprocessing time, where s is distinct symbols appearing in string \(Y\) and \(O(m)\) time to determines Longest Common Subsequences.

On the partition dimension of some wheel related graphs

JPRM-Vol. 1 (2008), Issue 1, pp. 154 – 164 Open Access Full-Text PDF
Imran Javaid, Sara Shoukat
Abstract: Let G be a connected graph. For a vertex \(v ∈ V (G)\) and an ordered \(k-\)partition \(Π = {S_1, S_2, …, S_k}\) of \(V (G)\), the representation of \(v\) with respect to \(Π\) is the \(k-\)vector r \((v|Π) = (d(v, S_1), d(v, S_2), …, d(v, S_k))\) where \(d(v, S_i) = min_{w∈S_i} d(v, w)(1 ≤ i ≤ k)\). The k-partition \(Π\) is said to be resolving if the k-vectors \(r(v|Π), v ∈ V (G)\), are distinct. The minimum \(k\) for which there is a resolving \(k\)-partition of \(V (G)\) is called the partition dimension of \(G\), denoted by \(pd(G)\). In this paper, we give upper bounds for the cardinality of vertices in some wheel related graphs namely gear graph, helm, sunflower and friendship graph with given partition dimension \(k\).

Contractible fibers of polynomial functions

JPRM-Vol. 1 (2008), Issue 1, pp. 148 – 153 Open Access Full-Text PDF
Zahid Raza
Abstract: In this short note, we investigate the topology of complex polynomials \(f(x, y)\) in two variables. The description of the topology of the corresponding level curves \(C_t : f(x, y) = t\) is directly related to the vanishing of the leading coefficients cj (t) of the discriminant of the polynomial \(f(x, y) − t\), regarded as polynomials in \(t\).

\(G_p\)-Finiteness of tensor product

JPRM-Vol. 1 (2008), Issue 1, pp. 143 – 147 Open Access Full-Text PDF
M.S. Balasubramani, K. T. Ravindran
Abstract: In this paper we introduce \(G_P\) finiteness of a Von-Neumann algebra and we define a G-dimension function. Then we prove a result on tensor product of fixed point algebra under group of automorphisms and finally verify a result under which the tensor product is \(G_P\) finite.
