Abstract: This paper introduces an optics based sensory system to improve the performance of the conventional and modern (developed so far) spirometry in terms of cost, functionality, reliability for the diagnosis of two common respiratory diseases like chronic obstructive pulmonary disease (COPD) and chronic restrictive pulmonary disease (CRPD). In our present work, we have incorporated a cordless optics based sensing system which carries many unique features which include i) no external hardware interfacing circuit (for communication of signal to the computing device) thus reducing hardware complexity ii) A noise free computer compatible output. In order to analyze the output (coming out from the sensing system), we have derived an algorithm for faithful reproduction of the breathing pattern graphically. At the same time, the significant spirometric values are displayed numerically. This makes a more reliable approach by storing the information for future analysis to have a meaningful solution

Abstract: As a result of restructuring in the electric power sector economic as well as environmental issues have led increased interest in distributed resources. Distributed generation (DG) is not entirely new concept but it is emerging approach for providing electric power in the heart of power system. It mainly depends upon the installation and operation of a portfolio of small size, compact, and clean electric power generation units at or near the load (customer). The increased penetration level of DG in the distribution network has changed its characteristics from passive to active .Therefore it is relevant to consider the applicability of some pricing mechanism in distribution network that are finding application in short term operation of transmission networks. In this paper a methodology is proposed for nodal pricing of distributed resources for different type of loads. The method recommends significantly greater revenue under nodal pricing reflecting its contribution to reduced losses.
