There is a growing need for industries to become accountable for their actions towards the environment. In order to make it possible, it is required to develop comprehensive, integrated and progressive environmental policies. These environmental policies would maintain dynamic environmental equilibrium. Today there is requirement by the National and International bodies to have standardised environmental management systems (EMS). These systems would keep the records of all environmental issues pertaining to the organisation. The EMS is made simple through the introduction of the ISO 14000 series. ISO 14000 provides guidelines on how to successfully manage and reduce environmental impacts through management functions, while at the same time allowing for high levels of socioeconomic growth and dedication to sustainable development. The implementation of EMS through ISO 14000 series would involve the expenditure. Every organisation is interested in economic aspects before the implementation of any system. They want that the system should provide the financial benefits, which will motivate to keep going on. This paper discusses economic aspects for the implementation of ISO 14000 an EMS tool in any organization with the help of cost of environment concept. The paper presents the concept of quality cost being applied to justify the implementation of EMS.

The essential problem in controlling robots is to make the manipulator follow a desired trajectory. This paper presents the genetic algorithm tuned fuzzy PID controller (GAFPID) to follow the desired trajectory for a three degree of freedom (DOF) robot arm. Numerical simulation using the dynamic model of three DOF robot arm shows the effectiveness of the approach in trajectory tracking problems. Comparative evaluation with respect to PD, PID and fuzzy PID controls are presented to validate the controller design. The results presented emphasize that a satisfactory tracking precision could be achieved using the proposed controller than conventional controller.

This paper presents the analytical solution of one-dimensional stresses for a hollow sphere made of functionally graded material. The material properties vary continuously across the thickness, according to power functions of radial direction. The thermal boundary conditions may include conduction, flux, and convection for inside or outside of hollow sphere. Thermoelasticity equation is steady state and include heat source. The aim of this work is considering the effect of heat source on thermal stresses. The heat conduction and Navier equations are solved analytically and a direct method of solution of Navier equation is presented.

The transmission control protocol (TCP) was designed to provide reliable end to end delivery of data over unreliable networks. Ignoring the properties of wireless adhoc networks can lead to poor TCP implementation. Therefore several transport layer protocol have been designed exclusively for adhoc network such as ATCP, ATP, TPA etc. Out of these protocols ATP finds to be more suitable for adhoc network. In ATP, the performance of sending TCP is concentrated but the performance and load of the intermediate node is not taken in to account while designing it. In this paper a simple approach is proposed to address the intermediate node problem by making it to operate in three layers rather than operating in four layers. This enhanced ATP is called as PATPAN.

Here we are presenting some novel techniques for squirting colors in grayscale images. The problem of coloring grayscale images has no exact solution. Here we are attempting to minimize the human efforts needed in manually coloring the grayscale images. We need human interaction only to find a reference color image, then the job of transferring color traits from reference color image to grayscale image is done by proposed techniques. In these techniques, the color palette is prepared using pixel windows of some degrees taken from reference color image. Then the grayscale image is divided into pixel windows with same degrees. For every window of grayscale image the palette is searched for equivalent color values, which could be used to color grayscale window. In the whole process the luminance values of reference color image and target grayscale image are only matched and based on best possible match the respective chromaticity values of color image are transferred to grayscale image. For palette preparation first we used RGB color space and then Kekre's LUV color space[9]. Results with Kekre's LUV color space were comparatively better. To improve the searching time through color palette the exhaustive and Kekre's fast search are used.

Fuzzy systems offer numerous methods that prove helpful in solving application problems, where the governing parameters bear fuzziness in nature. In particular, many variants of fuzzy decision making models have been successfully explored as vocational guidance systems to assist decision makers in recognition and guidance processes, specially in the Medical diagnostic realm. In the present communication, an attempt is made to unreveal the fact that even the precisely chosen text fragments from a closed world domain incorporate the fuzzy boundaries among their term-to-term associations for machine-assisted acquisition and subsequent evaluation of Natural Language Semantics of that domain. This inspires further, to provide a decision-making tool that assists the Academicians in assessing the online submitted subjective answers at the candidatespsila end.

Due to the explosion in the number of autonomous data sources, there is a growing need for effective approaches to distributed knowledge discovery and interactive data mining. In this paper, distributed VISTA system is proposed by extending existing visual cluster rendering system for distributed environment. First, all objects of local datasets are grouped using VISTA system and resulting centroids are considered as local models. Then, local models are combined to form a global model using VISTA. Finally, global clusters are automatically identified using global models and corresponding objects are visually explored. The experiments are carried out for various datasets of UCI machine learning data repository.

With the increasing popularity of Web services, attackers are getting attracted to hack the Web services and the servers on which they run. One of the major threats is that of intruders which may maliciously try to access the data or services. Thus there is a need to protect the servers on which Web services are running from intruders. Therefore, intrusion detection systems need to be employed. Signature based IDS are popularly being used. Honeypots are a highly flexible security tool with differing applications for security. They are a security resource that does not have any production or authorized activity but have an important use in intrusion prevention, detection and information gathering. Honeypot collects very little data and what it collects is normally of high value. This information can be used in extraction of intrusion detection signature. In this paper we have proposed a method to analyze the attacks and generate signatures for Web services.

A high-speed radix-64 parallel multiplier using novel reduced delay partial product generator is proposed. The use of radix-64 Booth encoder and selector for partial product generation by Sang-Hoon (Sang-Hoon Lee et al., 2002) reduces the number of partial product rows by six fold. The Booth selector selects one among X, 2X, 3X, 4X, 8X, 16X, 24X and 32X where X is the multiplicand. Before selection 3X computation must be completed which accounts for maximum delay because of carry propagation or carry look ahead addition of X and 2X. In this work this fundamental coefficient is generated as 4X-X using redundant binary (RB) arithmetic. This leads to zero delay for 3X computation as well as simplifies the partial product rows accumulation. This novel method of partial product generation decreases delay by 24% in comparison to last high-speed reported parallel multiplier (Sang-Hoon Lee et al., 2002) using radix-64 Booth encoding.
提出了一种基于新型减延迟部分积发生器的高速64根并行乘法器。Sang-Hoon (Sang-Hoon Lee et al.， 2002)使用radix-64 Booth编码器和选择器生成部分产品，将部分产品行数减少了六倍。展台选择器从X、2X、3X、4X、8X、16X、24X、32X中选择一个，其中X为乘数。在选择之前必须完成3X计算，这是由于X和2X的进位传播或进位前瞻相加造成的最大延迟。在这项工作中，这个基本系数是用冗余二进制(RB)算法生成的4X-X。这使得3X计算的延迟为零，并简化了部分乘积行累积。这种新颖的部分积生成方法与上一个高速并行乘法器(Sang-Hoon Lee et al.， 2002)使用基数64 Booth编码相比，延迟减少了24%。
