This process involves a data mining model -The data mining model encompasses the set of data, statistics and patterns that can be applied to new data to generate predictions and make inferences about relationships. This paper discusses some of the aspects related to how these structures can be created and manipulated for a variety of data. It also discusses how models can be created using several data mining techniques.

These normally consist of multiple choice questions-While this format is suitable for many types of examinations, one has to look at the student aptitude also while devising a question paper. There has to be a right balance between the strength of the students and the difficulty level of the questions. This balance is difficult to achieve. This paper discusses some techniques to know the students strengths and to devise questions based upon them. Data mining techniques, Item analysis, Regression analysis and probabilistic techniques are used here.

Human Resource Planning subsystem in an organization involves analyzing and forecasting the talent requirements of the organization. The main focus in the study was to construct and develop a system dynamic model for the human resource planning process.

The intense level of competition at this stage makes it difficult for both the candidate to answer the papers and the person to set the paper. While the standard of the questions have to be maintained throughout the examination paper it also has to be seen that there is a right balance between the severity of the questions and the strength of the candidates to answer. This balance is difficult to achieve. This paper discusses some probabilistic and statistical techniques to analyze the results of competitive exams at the post graduate level-and thereby evolve a predictive model for the future use in setting up the question papers. Data Mining softwares like Rapid Miner, Weka and R and statistical packages like SPSS can be employed suitably in order to do this kind of an analysis.

Human Resource planning subsystem in an organization involves analyzing and forecasting the talent requirements of the organization. The main focus of the study was to construct and develop a system dynamic model for the human resource planning process. System Dynamics is used as a research tool to provide useful insights for human resource planners in arriving at the strategic plans for the organization. These tools are deployed to develop a model for a multilevel organization structure with appropriate flows related to recruitment at various levels, promotion and attrition. The variables and factors included in the modeling process have been derived based on inputs obtained from the Human resource planners of leading IT organizations. The systematic methodology adapted in the study and presented in this paper details the assumptions in modeling, the construction of the causal loop diagrams involving the feedback and testing the model with inputs using the field data. The analysis of this initial conceptual model of the human resource planning problem is performed using a system dynamic simulation tool namely i- think. This model will help HR planners in generating implementable human resource plans. The study has helped in using the modeling framework as a means to understand the complex dynamics of the Human resource flows in an organizational environment.

achieving the shortest possible throughput time by eliminating wastes (Muda).
The research investigation addresses the application of lean manufacturing in
an auto part manufacturer which manufactures critical components of an IC
engine. The main objective of this research investigation was to identify key
areas of non-value added activities by utilising ‘value stream mapping’ (VSM)
and then to propose required changes to reduce throughput time based on the
principles of lean manufacturing. Three different improvements were suggested
as solutions for non-value added activities that were identified in the current
state map, which accounted for 250 hrs of throughput time. A reduction of
140 hrs in the throughput time was estimated by incorporating the
improvements.

The conceptual network model was developed to understand the call flow processes using simulation software Arena 9.0. The model was analyzed for major bottleneck processes under various scenarios including Normal Traffic Intensity, Worst Day traffic intensity and Ideal Day Traffic Intensity. The various performance parameters of cellular services which are measured includes: Value Added Time (VAT) in the system, Non Value Added Time (NVAT) in the system, Number of Calls Request denied, Number of Calls Dropped and Call Duration. The work includes the adaptation of the simulation model using arena to analyze cellular networks. The performance analysis reveals a large percentage of the time in the Call set up processes is spent on Non Value Added Activities. Recommendations for improvements in the Call set up processes have been proposed for future consideration along with action points for improving operational efficiency.

Though these initiatives are being implemented in the best possible manner, they are unable to deliver the same impact as seen in other developing counties in the Asia Pacific region which accounted similar conditions as India a few decades earlier. This paper studies the present condition of patenting in India in comparison to other countries in Asia Pacific region. One of the possible reasons for this can be the prioritization of Intellectual property as a facilitating tool in Innovation and technological advances. Intellectual Property Rights has established itself as a key enabler in promoting, protecting and nurturing the technological and research initiatives which are mandatory for the economic growth.

Competitive benchmarking is a Continuous process of comparing a firm's practices and performance measures with that of its most successful competitors. Competitive benchmarking is evaluating best practices from others to improve organization.This paper presents competitive benchmarking study of Indian postal network system (IPNS) helps to compare Indian postal service to other country services.

According to the recent reports by TRAI, Indian telecom sector has the lowest tariff in the world. Indian telecom market has 10-12 service providers striving for the market share at any point of time.
