In this paper, we introduce generalized cyclic C-contractions through p number of subsets of a probabilistic metric space and establish two fixed point results for such contractions. In our first theorem we use the Hadzic type t-norm. In our next theorem we use Lukasiewicz t-norm. Our results generalize the results of choudhury and Bhandari [11]. A control function [3] has been utilized in our second theorem. The results are illustrated with some examples.

In India energy auditors in some cases have recommended ground water based heat pump in place of common HVAC system to achieve better efficiency. However the users were made to understand that heat pumps are not suitable for Indian climatic condition and it produces no better result than the conventional system. This article tries to find answer to this debate thru an impartial analysis with the available data. First the concept is tested thermodynamically to compare the derived COPs and next from the experimental data on specific energy consumption.

In this paper, it is shown that for low-order uncertain systems, there is no need to calculate all the minimum and maximum values of the coefficients for a perturbed system which is expressed in terms of polynomials and hence no need to formulate and test all the four Kharitonov＇s polynomials. Furthermore, for higher-order systems such as n ≥ 5, the usual four Kharitonov＇s polynomials need not be tested initially for sufficient condition of perturbed systems; rather, the necessary condition can be checked before going for sufficient condition. In order to show the effectiveness of the proposed method, numerical examples are shown and computational efficiency is highlighted.

In this paper, a technique is presented to determine the stability margin of the discrete systems using recursive algorithm for power of companion matrix and Gerschgorin Theorem and hence sufficient condition of stability is obtained. The method is illustrated with an example and it is compared with other methods proposed in the literature. The results have applications in the filter design.

This paper tries to address the issue of expertise and awareness level of ISO-50001 [1] certification auditors in judging the efficacy of existing energy management (EnMS) and suggest the methodology to ensure continual improvement in EnMS. This article also tells about the need of thorough understanding of legal & other mandatory requirements which need to be addressed properly before framing the energy policy and setting up objectives & targets for the organization. Particularly SMEs, while implementing any standard or adopting any new system, largely depend on the consultant/ system auditor because of their limited knowledge and resources. In such cases the auditors need to play a larger role by making appropriate ENCON recommendations and guide them how to achieve the compliance. Further in India, most of the companies have got poor metering system. Even crucial energy data like flow rate of LPG, natural gas, FO, steam etc are quoted from judgment or past experience. Meters are not there to measure motor power, liquid temp or gas prss. In such cases auditors need to guide the clients how to establish the energy monitoring & targeting system and how to establish proper M&V (Measurement & Verification) protocol. In nut shell the ISO-50001 auditor needs to play the role of a friend, philosopher & guide to ensure that at the end of the day his client has complied with all the energy regulations and at the same time achieved some significant reduction in energy consumption.
