55. Some A-numerical radius inequalities for semi-Hilbertian space operators.

Author

Chandra Rout, Nirmal, Sahoo, Satyajit, and Mishra, Debasisha

Subjects
*POSITIVE operators
Abstract

In this article, we obtain some upper bounds for A-numerical radius of operators in semi-Hilbertian spaces which improve the existing ones. Furthermore, we discuss some generalizations of earlier A-numerical radius inequalities. We also establish several inequalities for B-numerical radius of n × n operator matrices, where B is an n × n diagonal matrix whose diagonal entries are positive operator A. [ABSTRACT FROM AUTHOR]

58. A-Berezin Number Inequalities for 2×2Operator Matrices

Author

Zamani, Ali, Sahoo, Satyajit, Tapdigoglu, Ramiz, and Garaev, Mubariz

Abstract

Let Abe the 2×2diagonal operator matrix determined by a positive Hilbert space operator A. We give several upper bounds for the A-Berezin number of 2×2block matrices on a reproducing kernel Hilbert space and prove inequalities for the A-Berezin number of Hilbert space operators. Our results in this paper generalize and refine earlier the A-Berezin number inequalities.

61. HEALTHY LIFE FOR ASTHMATIC PATIENTS.

Author

Govindbhai, Darji Yogeshkumar and Sahoo, Satyajit

Subjects
*DYSPNEA, *SMOOTH muscle, *CHRONIC diseases, *ASTHMA, *WHEEZE, *RHINITIS
Abstract

Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction and bronchospasm. Asthma is the result of chronic inflammation of the airways which subsequently results in increased contractability of the surrounding smooth muscles. This among other factors leads to bouts of narrowing of the airway. The narrowing is typically reversible with or without treatment. Occasionally the airways themselves change. Common symptoms include wheezing, coughing, chest tightness, and shortness of breath. [ABSTRACT FROM AUTHOR]

67. Quality Analysis in Phase Modulated Radio Over Fiber in WDM/DWDM Network

Author

Sahoo, Satyajit and Sahoo, Satyajit

Abstract

There has been increasing demand for connection setup with a higher quality of service (QoS) in WDM/DWDM networks, especially in fields like radio over fibers, where phase modulation affects the link quality. Hence to meet guaranteed QoS in a phase modulated link, the effects of phase modulation on link quality is very much needed. The link quality is termed as quality factor (Q-factor). The primary objective is to use effectively the connections available to optimize the computed number of connections and reduce the blocked connections but at the same time guarantying QoS as per client’s need. The analysis has been done by taking care of routing and wavelength assignment (RWA) techniques. The performance analysis is presented in terms of blocking probability. This work includes detailed mathematical analysis of how phase modulation affects link Q-factor.Eight bands complimentary inner outer band, four bands complimentary inner outer band, and middle outer band wavelength assignment techniques are used for analysis.Blocking probability versus connection requests, blocking probability versus wavelengths assigned, connections accepted for a given source-destination pair were analyzed for different wavelength assignment techniques.
