The economic reforms- Liberalization, Privatization, Globalization, (LPG) started in 1991 in India. The main objective of the government was to achieve high economic growth and industrialize the nation for the well-being of Indian citizens. Thus Indian market became Global and open market. Coal industry was not an exception to this phenomena of globalization. The improvement in productivity has become need of coal industry to take the competitive advantage of global market. The challenge to the coal Industry is to identify the wastes and meet the market price by maintaining a good profit. The only solution is to reduce total production cost. Lean manufacturing is a systematic approach to identify and eliminate the waste through continuous improvements and synchronizing the production process to obtain manufacturing excellence. This can be achieved by Lean thinking (to identify and eliminate wastes) and Lean production (to improve efficiency and effectiveness of equipment). Earlier the lean manufacturing concept was limited to manufacturing organization now it is used invariably in operation industries. In this paper researcher has applied lean manufacturing concept in order to increase productivity and to minimize the production cost of mining.

Electro-absorption (EA) modulators are very attractive devices for optical fiber communications because of their very low driving voltage, very high modulation efficiency and integratibility with lasers. However, conventional EA modulators are lumped electrode devices, whose speeds are limited by the total parasitics of the devices, which restricts the devices to very short length for high speed operation. This paper has presented the important transmission characteristics of EA modulators such as transmission performance efficiency, modulation photocurrent, insertion loss, extinction ratio, relative refractive index difference, and signal transmission quality, over wide range of the affecting parameters for different selected electro-absorption materials to be the major of interest.

The technology involves a new type of compact device based on magneto-optics in a fiber micro modulator. This type of modulator allows the user to inter manipulate and control the propagation of the incoming light. The operation mechanism uses external magnetic field to manipulate Fe micro particle in order to cause modulation of an optical signal that propagates along an optical waveguide. This paper has presented yttrium iron garnet (YIG) and lithium niobate (LiNbO3) which are examined for use as a wideband magneto-optic modulator. A wideband YIG modulator has recently been developed which represents a great improvement over other magneto -optic modulators.

Face recognition has received a great deal of attention from the scientific and industrial communities over the past several decades owing to its wide range of applications in information security and access control, law enforcement, surveillance and more generally image understanding. In this paper we combine KLDA(combination of LBP and GABOR features) with gradient face features(which are more resistive to the noise effects) for more effective recognition process. Specifically, we make three main contributions: (i) we present a simple and efficient preprocessing chain that eliminates most of the effects of changing illumination while still preserving the essential appearance details that are needed for recognition; (ii) we introduce Local Ternary Patterns (LTP), a generalization of the Local Binary Pattern (LBP) local texture descriptor that is more discriminant and less sensitive to noise in uniform regions, and we show that replacing comparisons based on local spatial histograms with a distance transform based similarity metric further improves the performance of LBP/LTP based face recognition; and (iii) we further improve robustness by adding Kernel PCA feature extraction and incorporating rich local appearance cues from two complementary sources - Gabor wavelets and LBP - showing that the combination is considerably more accurate than either feature set alone.

Traditional image coding technology mainly uses the statistical redundancy between pixels to reach the goal of compressing. The research on wavelet transform image coding technology has made a rapid progress. Because of its high speed, low memory requirements and complete reversibility, digital wavelet transform (IWT) has been adopted by new image coding standard, JPEG 2000. The embedded zero tree wavelet (EZW) algorithms have obtained not bad effect in low bit-rate image compression. Set Partitioning in Hierarchical Trees (SPIHT) is an improved version of EZW and has become the general standard of EZW So, In this paper we are proposing DWT and SPIHT Algorithm with Huffman encoder for further compression and Retinex Algorithm to get enhanced quality improved image.

This research was carried to evaluate the possible effects of ginger on the male reproductive system. Infertility is one of the major health problems in animals, approximately 30 % of infertilities are due to a male factor. Twenty animals were divided into four groups of five animals each and maintained under standard laboratory conditions of 27 + 2oC, relative humidity 50 + 15% and normal photo period (12h dark/12h light). The extract was given orally once per day for 21 days with diluted ethanolic extract of ginger. There were increases in normal sperm and level of normal sperm, though not statistically significant. In motility there were no significant differences as well when compared with the control. Treatment of the testes with 0.2ml/kg, showed tick cell membrane and the cells are fibrous in nature, while those treated with 0.4ml/kg and 0.8ml/kg showed fusion of cells, congestion and distortion of cell membrane of the seminiferous tubules. Ginger aids in the production of healthy sperm but should be take with care as it can also damage the cell membrane of the testes.

Now we have realized that our economic activities and zest for quick development are threatening the very survival of mankind over the earth. Our survival depends on the realization that we have to live in harmony with the various elements of environment which are interconnected. This realization of relationship between man and environment resulted into the dictum that poverty leads to environmental degradation. Further their ignorance towards limitations of resources use and consequences make them free to over exploit the natural resources and adversely affect the natural system of environment and put a question mark over the notion of sustainable development. The widely propagated nation about the positive relationship between poverty and environmental degradation may not be operative in India. The study clearly shows that poverty has to do nothing with environmental degradation

Agriculture data is highly diversified in terms of nature, interdependencies and resources. For balanced and sustainable development of agriculture these resources need to be evaluated, monitored and analyzed so that proper policy implication could be drawn. Recently knowledge management in agriculture facilitating extraction, storage, retrieval, transformation, dissemination and utilization of knowledge in agriculture is underway. Data mining techniques till now used extensively in business and corporate sectors may be used in agriculture for data characterization, discrimination and predictive and forecasting purposes. Some use of data mining in soil characteristic evaluation has already been attempted. This paper attempts to bring out the characteristic computational needs of agriculture data which is essentially seasonal and uncertain along with some suggestion regarding the use of data mining techniques as a tool for knowledge management in agriculture.

Sexually transmitted diseases (STDs) share common symptoms and can be classified as confusable disease, as such become difficult for physicians to correctly diagnose them. This work develops a pattern recognition system for the diagnosis of gonorrhea disease using genetic algorithm. Data on gonorrhea symptoms are collected and used in the development of the knowledge base. We classify the membership grade of the symptoms based on the mean of maxima and the derived membership function. The system accepts symptoms as input and provides the degree of membership of each symptom in any gonorrhea symptoms sets. We develop our system using PHP programming tool as back end and Java as front end platform. We explore Ms Access for the design of our database. The model helps the physicians to identify gonorrhea disease by its symptoms and provides solid basis for possibly determination of the ailment exactly if there are all symptoms.

Production of anthracnose-free mango fruits in Southwestern Nigeria rely heavily on the use of synthetic pesticides. But the hazardous effects of these pesticides on both human and the environment especially among illiterate farmers in the region offsets their benefits. This study, investigated the effect of aqueous and alcohol extract of Anonna squamosa, Azadirachta indica and Vernonia amygdalina in the control of fruit anthracnose disease of mango. The result of the investigation revealed that there was a significant reduction in the development and severity of anthracnose lesions on mango fruits treated after harvest with aqueous and alcohol extracts of the three indigenous plants. One-way ANOVA with Duncan Multiple Range Test conducted revealed that, the least disease index of 0.27 was recorded in both 10% (aqueous extract) and 30% (alcoholic extract) concentrations of Annona squamosa treatments and this was superior to 0.33 disease index recorded in benomyl treated fruits. Based on the result of this investigation, the three tested indigenous plants have the potential of good candidates for the replacement of synthetic pesticides in the control of fruit anthracnose disease of mango.

Two simple and sensitive visible spectrophotometric methods are described for the determination of almotriptan malate in bulk and pharmaceutical preparations based on the formation of colored molecular complex with sodium nitroprusside in presence of hydroxyl amine under alkaline conditions (M1) or SNP-acetaldehyde reagent (M2) and exhibiting λ max at 720 nm or 550nm respectively. The Regression analysis of Beer's Law plot showed good correlation in a general concentration range of 8-40g/ml or 4.0-20g/ml with correlation coefficient (r= 0.998) for methods M1 and M2 respectively. The proposed methods are validated with respect to accuracy, precision, linearity and limit of detection. The suggested procedures are successfully applied to the determination of the drug in pharmaceutical preparation, with high percentage of recovery, good accuracy and precision. The results of analysis have been validated statistically by repeatability and recovery studies. The results are found satisfactory and reproducible. These methods are applied successfully for the estimation of almotriptan in tablet form without the interference of excipients.

In this paper we analyze the performance and characteristics of DG MOSFET with high-k material on both top and bottom gate stack and compare those with conventional pure SiO2 DG MOSFETs. We investigate the performance of the device in terms of drain current, threshold voltage and subthreshold slope using 2D quantum simulator nanoMOS 4.0. The noticeable impact of temperature is also observed both on the threshold voltage and subthreshold characteristics. This structure shows improved performance, achieved by scaling the gate length and illustrates its superiority over conventional DG MOSFETs and DG MOSFETs with only top gate stack in achieving long term ITRS goals.

Fingerprint recognition is one of the most popular and successful methods used for person identification, which takes advantage of the fact that the fingerprint has some unique characteristics called minutiae; which are points where a curve track finishes, intersect with other track or branches off. A critical step in studying the statistics of fingerprint minutiae is to reliably extract minutiae from the fingerprint images. However, fingerprint images are rarely of perfect quality. They may be degraded and corrupted due to variations in skin and impression conditions. Thus, image enhancement techniques are employed prior to minutiae extraction to obtain a more reliable estimation of minutiae locations. The goal of this paper is to represent a complete process of fingerprint feature extraction for minutiae matching.

This paper presents a new design of static and Domino logic using CMOS. Domino logic is a CMOS based evolution of the dynamic logic techniques based on either PMOS or NMOS transistors. It allows a rail-to-rail logic swing. It was developed to speed up circuits in Dynamic Logic. They have smaller areas than conventional CMOS logic (as does all Dynamic Logic) and parasitic capacitances are smaller so that higher operating speeds are possible. There are many solutions to the problem of how to cascade dynamic logic gates. One way is Domino Logic, which inserts an ordinary static inverter between stages. While this might seem to defeat the point of dynamic logic, since the inverter has a PFET (one of the main goals of Dynamic Logic is to avoid PFETs where possible, due to speed), there are two reasons it works well.
