Orbital Spin: A New Hypothesis to Explain Precession of Equinox—The Third Motion of Earth  [PDF]
Rama Chandra Murthy Mothe
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.41004

In this paper, the phenomena of Earth’s motion about its own axis, the ecliptic plane of the Earth’s orbit around the Sun, the definitions of equinoxes, the precession of equinoxes, Earth’s wobble and other astronomical terminology are briefly described. Some of the existing theories explaining the precession of equinox and their inadequacies are brought out. New Hypothesis is that precession of equinoxes is a direct result of Orbital spin of Earth in a retrograde direction—a celestial phenomenon similar to that of Moon’s Orbital spin around the Earth. The study of Moon’s orbit round the Earth reveals the exact movement of Earth’s orbit, which causes precession of equinoxes without any ambiguity. The analogy presented herein demonstrates the plausible hypothesis.

Innovative Structured Matrices  [PDF]
Rahul Gupta, Garimella Rama Murthy
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2013, DOI: 10.4236/alamt.2013.33004

Various directions of obtaining novel structured matrices are discussed. A new class of matrices, called “the L-family” matrices are introduced and their properties are studied.

Speech Enhancement Using Cross-Correlation Compensated Multi-Band Wiener Filter Combined with Harmonic Regeneration  [PDF]
Venkata Rama Rao, Rama Murthy, K. Srinivasa Rao
Journal of Signal and Information Processing (JSIP) , 2011, DOI: 10.4236/jsip.2011.22016
Abstract: The speech signal in general is corrupted by noise and the noise signal does not affect the speech signal uniformly over the entire spectrum. An improved Wiener filtering method is proposed in this paper for reducing background noise from speech signal in colored noise environments. In view of nonlinear variation of human ear sensibility in frequency spectrum, nonlinear multi-band Bark scale frequency spacing approach is used. The cross-correlation between the speech and noise signal is considered in the proposed method to reduce colored noise. To overcome harmonic distortion introduced in enhanced speech, in the proposed method regenerate the suppressed harmonics are regenerated. Objective and subjective tests were carried out to demonstrate improvement in the perceptual quality of speeches by the proposed technique.
A Novel Routing Algorithm for Vehicular Sensor Networks  [PDF]
Mohammad Jalil Piran, Garimella Rama Murthy
Wireless Sensor Network (WSN) , 2010, DOI: 10.4236/wsn.2010.212110
Abstract: Recent advances in wireless communications are diffusing into many new applications. The tiny sensor node, which consists of sensing, data processing and communicating components, led to the idea of sensor networks. A sensor network composed of a large number of sensor nodes that are densely deployed either inside the phenomenon or very close to it. The applications envisioned for sensor networks vary from monitoring inhospitable habitats and disaster areas to operating indoors for intrusion detection and equipment monitoring. In most cases the network designer would have little control over the exact deployment of the network. Nowadays Vehicular Networks are drawing lots of attention due to the wide variety of applications that they can provide. These applications include traffic monitoring, positioning, security etc. A lot of research work is being conducted to define the standard for vehicular communication. These include frequency allocation, standards for physical and link layers, routing algorithms, security issues and new applications. In this paper we discuss the disadvantages of the traffic monitoring by traditional methods and by using GPS equipped sensors. Then we propose a new routing protocol for a fixed topology containing both stationary and mobile nodes. We also try to optimize the energy of the sensor nodes. We simulate our routing algorithm in MATLAB and evaluate it for different possible cases.
Study of Stability Analysis for a Class of Fourth Order Boundary Value Problems  [PDF]
C. Bala Rama Krishna, P. S. Rama Chandra Rao
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513182
Abstract: Fourth order differential equations are considered to develop the class of methods for the numerical solution of boundary value problems. In this paper, we have discussed the regions of absolute stability of fourth order boundary value problems. Methods proposed and derived in this paper are applied to solve a fourth-order boundary value problem. Numerical results are given to illustrate the efficiency of our methods and compared with exact solution.
Fundamental Limits on a Model of Privacy-Trust Tradeoff: Information Theoretic Approach
Rama Murthy Garimella
International Journal of Network Security , 2006,
Abstract: Zhong et al. formulated the problem of disclosing credentials (associated with privacy) for building trust in an open environment like Internet. Thus, one form of privacy-trust problem is formulated in [17]. In [17], an entropy measure is defined to quantify privacy loss. In this research paper, by a proper formulation (modelling), the privacy-trust tradeoff is attacked from the Information Theoretic view point. It is shown that as long as privacy loss (or more accurately a measure related to privacy loss) is below a limit, through the use of properly coded credentials, it is possible to achieve arbitrarily good trust. The approach presented here will lead to several practical schemes in trading privacy for trust.
Structured Multi-Matrix Variate, Matrix Polynomial Equations: Solution Techniques
Garimella Rama Murthy
Mathematics , 2012,
Abstract: In this research paper, structured bi-matrix variate, matrix quadratic equations are considered. Some lemmas related to determining the eigenvalues of unknown matrices are proved. Also, a method of determining the diagonalizabe unknown matrices is provided. The results are generalized to multi-matrix variate, matrix polynomial equations. Briefly generalization to tensor variate polynomial equations is discussed. It is hoped that the results lead to important contributions in "non-commutative algebra".
