| Price and Demand for Equity Shares in Voucher Privatization in the Cezch Republic | ||||||||||||
The Czechoslovak (later Czech) government began the process of privatizing companies. Vouchers were used to privatize substantial portions of the economy during five rounds. The core of these voucher schemes was the use of artificial money (vouchers) to purchase shares of privatized companies. This paper analyzes the relationship between the price and demand of equity shares using econometric modeling package – STATA and TSP. The price of equity shares in the current round and the corresponding individual demand was negative. However, this was not the case only for the second round where derived a positive. This unusual result interpreted in a way that high share prices of the second round could have been a signal in the very beginning to separate more successful companies, which attracted potential investors, therefore, increasing its price even further. This resulted in higher price in the second round lead higher individual demand. [1]. DEGROOT, M. Optimal Statistical Decisions. Mellon University, John Wiley & Sons, INC Publication, 2004. [2].

| Colorimetry Based Calcium Measurement | ||||||||||||
Calcium Analysis is one of the significant parameter for the clinical diagnosis. Calcium controls osmosis and diffusion through the cell membranes, and also the passing of information within the cell. Normal range of Calcium in human serum is around 8.5mg/dl-10.5mg/dl. The paper is focused on the Colorimetric Sensing technique for measurement of calcium. Colorimetry is a useful analytical tool for determining concentration of colored material in the solution. This sensing technique consists of LED as a light source of 650nm and a high speed photodiode BPW34 as a detector. Calcium reacts with ArsenazoIII and forms a colored complex. Concentration of calcium is measured by measuring the absorbance using Beer Lambert's law. The paper describes the test preparation and measurement procedures. The designed colorimetric sensing system is maintenance free and is cost effective.

| Image Enhancement Using Histogram Equalization Based On Genetic Algorithm | ||||||||||||
Image enhancement is one of the challenging issues in low level image processing. Contrast enhancement techniques are used for improving visual quality of low contrast images. Histogram Equalization (HE) method is one such technique used for contrast enhancement. It is a contrast enhancement technique with the objective to obtain a new enhanced image with a uniform histogram. In this paper, instead of using conventional image enhancement techniques, we proposed a method called genetic algorithm for the enhancement of images. This algorithm is fast and very less time consuming as compared to other techniques such as global histogram equalization by taking CDF and finding out the transfer function. Here in our work we are going to enhance images using histogram equalization of images by reconfiguring their pixel spacing using optimization through GA (Genetic algorithm). We will get more optimized results with the use of GA with respect to other optimization techniques.

| The Effects of Exhaust Gas Recirculation on Exhaust Emission and Combustion Characteristics of a CI engine operated on Diesel and WCO Biodiesel | ||||||||||||
Biodiesel has come to a forefront to be an alternative fuel to diesel in CI engines to reduce the diesel consumption and reduce the environmental degradation. The objective of this work is to elicit the problem with Biodiesel usage results in higher NOx emissions when compared to Diesel Engines and to reduce the NOx emissions with the help of Exhaust Gas Recirculation (EGR). CO, HC, NOx and smoke concentration of the exhaust gas were measured to estimate the emissions characteristics of a single cylinder four stroke air cooled direct injection (DI) diesel engine. Detailed analysis of various blends of biodiesel and diesel was made, to elicit the precise benefits of its extensive usage in CI engines. This analysis showed results indicating reduction in NOx emissions with the help of EGR with little compromise in power output.

| Approach to build MPLS VPN using QoS capabilities | ||||||||||||
A new standard for a new world of networking, MPLS is a forwarding mechanism based on Tag Switching. MPLS is an innovative approach in which forwarding decision is taken based on labels. It also provides a flexible and graceful VPN solution based on the use of LSP tunnels to encapsulate VPN data. VPNs give significant added value to the customer over and above a basic best effort IP service, so this represents a major revenue-generating opportunity for SPs. Multi-protocol Layer Switching (MPLS) VPNs are best solution for medium and large enterprises that currently deploy site-to-site VPN services. MPLS provides sophisticated traffic engineering capabilities that, coupled with IP QoS, enable multiple classes of service so business critical applications are treated with higher priority than less important applications and "best effort" services. We first present background on MPLS VPNs as well as QoS routing. Also we suggest some enhancements that will help to design the ideal MPLS VPN.

Companies spend millions of dollars to build data warehouses to hold their data and data mining applications must take advantage of this. Besides saving significant manual effort and storage space, relational integration allows data mining applications to access the most up-to-date information available. To collect large data is very tedious and frustrating task. There are various kinds of valuable semantic information about real-world entities embedded in web pages and databases. Extracting and integrating these entity information from the Web is of great significance.

| A Monotone Process Replacement Model for a Two Unit Cold Standby Repairable System | ||||||||||||
In this paper a two unit cold standby repairable system with two monotone processes exposing to
exponential failure law, is studied under the assumption that each component after repair is not as good as new.
Under this assumption we study an optimal replacement policy N in which we replace the system when the
number of failures of component 1 reaches N. We determine an optimal repair replacement policy N* such that
the long run average lose is minimized. We derive an explicit expression of the long-run average lose and the
corresponding optimal replacement policy can be determined analytically. Numerical results are also established
to highlight the theoretical results.

| Knowledge Management Process Influencing Core Competencies of Supervisors in the Electricity Generation Process | ||||||||||||
The objective of this research were to investigate Structural Equation Modeling (SEM) and to study the influence of Knowledge Management (KM) on the core competencies of supervisors in the electricity generation process. The paper focuses in particular on the relationship between the KM process and the core competencies of supervisors. The paper is based on personal interviews. Data was collected from 635 supervisors involved in operation and maintenance of power plants utilizing a case study done in Thailand. A framework of the SEM of KM influencing the core competencies of supervisors was developed from a detailed literature review in an attempt to define the relationship between the KM process and the core competencies of supervisors in the electricity generation process. The applicability and validity of the framework were verified by quantitative research methods. Findings -The paper finds that hypotheses were tested using the SEM. Test of hypotheses revealed that the KM process positively and significantly influenced the core competencies of supervisors in the electricity generation process. These findings tend to corroborate our conceptual model and are also in line with the existing literature. The KM process was found to significantly affect the core competencies of supervisors, indicating the importance of the context and background of the KM process performing together in cases that affect the core competency. Originality/value -This paper enhances understanding of the influence of the KM process on the core competencies of supervisors.
