The methanolic extract of the leaves of Cordia dichotoma at 300 mg/kg and 500 mg/kg were studied for hepatoprotective action in male Wistar rats by inducing liver damage using carbon tetrachloride...
Application of support vector machines for fault diagnosis in power transmission system (2008)
Ravikumar, B, Thukaram, D, Khincha, HP
Post-fault studies of recent major power failures around the world reveal that mal-operation and/or improper co-ordination of protection system were responsible to some extent. When a major power...

Stored glycogen is an important source of energy for skeletal muscle. Human genetic disorders primarily affecting skeletal muscle glycogen turnover are well-recognised but rare. We previously...
The Return to Capital and the Business Cycle (2007)
Gomme, Paul, Ravikumar, B, Rupert, Peter
We measure the return to capital directly from the NIPA and BEA data and examine the return implications of the real business cycle model. We construct a quarterly time series of the after-tax return...
Thukaram, D, Khincha, HP, RaviKumar, B
Phase-wise unbalanced reactive power compensations are required in distribution systems for dynamic power factor correction and terminal voltage stabilization. Shunt compensators are generally used...
A Generalized Volatility Bound for Dynamic Economies (2003)
Christopher Otrok, B. Ravikumar, Charles H. Whiteman
We develop a generalization of the Hansen-Jagannathan (1991) volatility bound that (i) version of the bound. This generalization enables us to judge whether models match important aspects of the data...
Christopher Otrok, B. Ravikumar, Charles H. Whiteman
We use recent statistical tests, based on a 'distance' between the model and the Hansen- Jagannathan bound, to compute the rejection rates of true models. For asset-pricing models with time-separable...
A Simplified NP-complete MAXSAT Problem (2001)
B. Ravikumar, S. Srinivasa Rao
It is shown that the MAX2SAT problem is NP-complete even if every variable appears in at most three clauses. However, if every variable appears in at most two clauses, it is shown that it (and even...
Parallel Algorithms for Finite Automata Problems (2000)
: Finite automata are among the most extensively studied and understood models of computation. They have wide ranging applications - for example, in image compression, protocol validation, game...
A Note on Maximal Prefix Codes (2000)
A sufficient condition is established for a maximal prefix code to be synchronous. Under this condition, an upper-bound on the length of the shortest synchronizing word is established. 1 Introduction...

Peg-Solitaire, String Rewriting Systems and Finite Automata (1997)
We consider a class of length-preserving string rewriting systems and show that the set of encodings of pairs of strings ! s; f ? such that f can be derived from s using the rewriting rules can be...
A Parallel Algorithm for Minimization of Finite Automata (1996)
In this paper, we present a parallel algorithm for the minimization of deterministic finite state automata (DFA's) and discuss its implementation on a connection machine CM-5 using data parallel and...
Randomized Parallel Algorithms For The Homing Sequence Problem (1996)
Homing sequences play an important role in the testing of finite state systems and have been recently used in learning algorithms due to Rivest and Schapire [17] and Freund et al. [4]. It is...
Implementing Sequential and Parallel Programs for the Homing Sequence Problem (1996)
Homing sequences play an important role in the testing of finite state systems and have been used in a number of applications such as hardware fault-detection [7], protocol verification [4], and...
The Missing Link And The Top-Spin (1996)
The missing link and the top spin are two puzzles closely related to Loyd's 15-puzzle. Basic group-theoretic machinery required to solve these puzzles is presented along with their complete...
Surajit Ray, B. Ravikumar, N. Eugene Savin
In this paper, we examine the robust Wald test statistic for SUR systems with adding up restrictions where the same explanatory variables are present in all equations and where heteroskedasticity...
The return to capital and the business cycle
Paul Gomme, B. Ravikumar, Peter Rupert
Real business cycle models have difficulty replicating the volatility of S&P 500 returns. This fact should not be surprising since real business cycle theory suggests that the return to capital...
The Return to Capital and the Business Cycle

We measure the return to capital directly from the NIPA and BEA data and examine the return implications of the real business cycle model. We construct a quarterly time series of the after-tax return...
