Policy of foreign direct investment liberalisation in India: implications for retail sector

This study has analysed the impact of liberalisation of Indian economy and FDI policy on the retail sector since its implementation in the 1990s. It also further analyses sub-categories by investigating its impact on the unorganised retail sector and the flow of FDI in single-brand retail and multi-brand retail sectors. A comprehensive and critical review of the existing evidence on the subject was carried out, and descriptive statistical analysis of data from 1991 to 2013 was performed which leads to conclude that the policy of FDI liberalisation has proved to provide diversification and sustainable development to the Indian economy and specifically retail sector which is considered to be one of the significant pillars of economy. Furthermore, for continuous growth of the economy, it seems vital to encourage more investment in other sectors by liberalising the restrictive policies

Computer Aided Design of Centrifugal Pump

The design of centrihgal pump involves a large number of empirical data derived from experimental evaluation of pumps. For any small change in input details, it requires a complete rework of design procedure. Even after following this detailed, time consuming procedure, it was very difficult to explain the geometry of the pump elements. This paper discusses the optimisation and computerisation of the design procedure of single stage centrifUga1 pumps. The design procedure was developed using Graphical User Interface software with Visual Basic 5.0 and interfaced with a specially developed AutoLISP program in AutoCAD R13 environment. An algorithm for generating the Cartesian co-ordinates of the designed pump elements was evolved and incorporated in the program, which are used to show the geometrical shapes of the pump elements and also used as an input data for the Auto LISP program for generating three-dimensional views of the pump components. The options and utilities made available through a single program enables the user to design, view, redesign and optimize the pump geometry till it reaches a satisfactory value. The developed software is user-friendly and can be used as a design tool to configure an optimum pump geometry for a given duty like discharge and head
