A model for optimal planning of radial distribution networks using the mixed integer quadratic programming technique is presented in this paper. The paper proposes a simplified load flow model for radial networks, and then the model is modified to be used in the planning process. An objective function composed of the capital cost and cost of energy losses is formed. The energy loss cost is developed as a quadratic function in both real and reactive power flow. The verification of the presented model has been made through its application to a 24-bus radial distribution network.

In this Information Communication Technology era the education institutes are serving their services through its websites. Website plays a very significant role or bridge between educational institutes and its end users. Educational Institutions websites provides a connection to utilize the library resources to its users by giving a link to enter to the library. In this regard the library website is now considered as an integral part of the library services and the efforts to develop library website is growingcloser over the pastperiod. An effort was made to analyse the Medical college websites of Kerala state,along with analyzing the contents of the websites. The data collected from the study were tabulated on the aspects of elements, based onLibrary holdings, services and facilities provided by the websites.

| Paper Title | :: | Resource Prioritization and Task Allocation in Field Services using Fuzzy MCDM and MINLP |

Field service is a network of functionalities designed to fulfill demands at customer site. The focus of field service is to improve financial performance and customer service level through smart resource allocation. Researchers have attempted to build a flexible and approachable resource selection and allocation model. Developing hybrid modelsusing multi criteria decision making technique (MCDM) need attention. In this research, a hybrid fuzzy analytic hierarchy process (FAHP) and fuzzy preference ranking organization method for enrichment evaluation (FPROMETHEE) are proposed for resource prioritization. Mixed Integer non-linear programming (MINLP) model is used for resources allocation in field service. This work is to maximize the total value of resource allocation during the execution of power plant maintenance.

The present study deals with assessment of stability in rock slopes using Geo-mechanical (RMR and SMR) and Kinematic technique. Attempt has been made to determine the class of instability using SMR method and determine factor of safety using planar and wedge technique. The present paper mainly explains the analysis of the instability of slope of railway cut slope present in 403 to 403A. Extensive field study was carried out to understand the behavior of rock mass. Laboratory experiments have been conducted to determine the various physical and mechanical properties of the rock mass. These properties have been used as input parameters for geo-mechanical and kinematic analysis. The possible failure modes were determined for the vulnerable slopes. In this study, analyses of rock slope stability were performed. The RMR result shows, 403/1, 403A/2 and 403/5 rock section depicts class III, III, and III respectively. As per Slope Mass Rating 403/1, 403A/2 and 403/5 come under partially stable condition, and 403/1- J3 comes under very unstable condition. The detailed Kinematic analysis carried out in 403/1 - J1, J2, 403A/2 - J2 and 403/5 – J2 for planar analysis and 403/1 – J1 – J2, 403/5 – J1 – J3, J2 – J3 and 403A/2 – J1 – J3, J2 – J3 are fulfil Hock and Bray wedge analysis. The Planar analysis shows 403/1 J3 and 403A/2 J2 are shows unsafe condition (FOS < 1) and 403/5 J2 and 403/1 J1 are safe (FOS > 1) in dry condition and unsafe in fully saturated condition. In Wedge analysis shows rock slopes 403/5 J1 – J3 is unsafe condition (FOS < 1) and other wedges are shows safe in condition (FOS > 1). The slope needs proper attention to minimize the regular and frequent failure every year mainly after the rainy season.
