Organizations increasingly utilize Web Content Management Systems (WCMS) to improve development speed, online flexibility and cost effectiveness for web applications. However, organizations lack the organizational processes and structure to effectively maintain WCMS. We propose a WCMS Process Framework for the operation and maintenance phase of Web Engineering. In this paper we elaborate on the construction of the framework. It encompasses the description of a generic IT Management framework and the inclusion of Web Content Management processes into a strategic, tactical, and operational level. The framework is validated through an expert validation consisting of three industry experts and a case study at a large Dutch telecommunications services provider. The case study substantiates our vision that the WCMS Process Framework contains a set of process descriptions that effectively supports the operations and maintenance of web applications.

Support vector machine Recursive feature elimination (SVM-RFE) is investigated for feature selection from Spam E-mail Database. Features selected using SVM-RFE are classified using support vector machines. The proposed method outperforms existing methods in terms of classification accuracy, number of selected features and computational efficiency. The recursive feature elimination method reduces the feature space by removing some of the (non-relevant) features. Experimental results presented in this paper confirm the uses of the SVM-RFE for the analysis of Spam E-mail data. For the one data set, the overall performance measure increases from 75% to 93% with the proposed approach.

In recent years, the growing number of digital audiovisual media files available over the internet or even on users hard discs is overwhelming. In order to support efficient storage and retrieval of those data, several comprehensive and rich multimedia retrieval systems (MMRS) have been introduced. Unfortunately, a standardized query format does not yet exist and almost every retrieval framework provides its own proprietary solution. Therefore, the ISO/IEC SC29 WG11 committee decided to contribute to this application by establishing the MPEG Query Format (MPQF). The MPQF is currently in Final Committee Draft (FCD) status and provides besides the standardization of messages from and to multimedia services also functionalities for service discovery, aggregated services and definition of service capability descriptions. In this context, the paper briefly introduces the MPQF and concentrates thereby on the management part. Based on this, a Web Service based framework is presented that realizes the management functionalities of MPQF. One of its central novel features is the distribution of a MPQF request to multiple multimedia services and the aggregation of individual result sets.

Parallel computing plays a major role in the current trends and in almost all the fields. Formerly they are useful only to solve very huge problems such as weather forecasting, and in scientific research such as protein exploration, etc. But nowadays the concept of parallel computing are used starting from super computing environment to the modern desktop environment such as quad-core or in the GPU usage. Hence the awareness of parallel computing is a must and is unavoidable. When we are moving towards parallel computing, the nature is the jobs which we are going to be processed is not always be independent. Some processes may be independent and some may not, due to the communication overhead between the processes. We should consider for all the processes while scheduling. This paper tends towards the important essence to be considered for co-scheduling on parallel jobs while scheduling.

Digital watermarking is a core technology for the copyright protection of multimedia digital content circulated on the Internet. A web based watermarking technique is proposed to embed watermark text, watermark image and a digital signature into the image. An immense amount of study has gone into crafting an algorithm for creating and inserting watermarks into a digital image. The proposed algorithm offer added controls to image proprietors by integrating benefits of using Internet to the watermark scheme. Experimental results prove that our projected watermarking technique provides steady protection to the ownership rights, gives good image quality and are robust in varying degree to JPEG compression and low-pass filtering. The application compresses the images to nearly 50%, decrease the computation time, reduces the web server space (to nearly 33.7%) and the image so created displays clear watermark on the image for immediate claim of ownership and authorship.

The Self-Organising Map (SOM) has been proposed as an alternative interface for exploring Digital Libraries or other big document collections, in addition to conventional search and browsing. With advanced visualisations assisting the user in understanding the contents of the map and its structure, as well as advanced interaction modes as zooming, panning and area selection, the SOM becomes a feasible alternative to classical search interfaces. Several applications show the SOM's utility for this task. However, there are still shortcomings in helping the user understanding the ma, which is essential to fully exploit the SOM's potential as an Information Management tool. There are insufficient methods developed for describing the map to support the user in the analysis of the map contents. In this paper, we give an overview of existing techniques and applications of SOMs in Digital Libraries, and present recent work in assisting the user in exploring the map by automatically describing maps using advanced labelling and summarisation of map regions, focusing on text collections. Therewith, the SOM becomes an attractive tool for Information Management in large corpora.

In a content based image retrieval system, target images are sorted by feature similarities with respect to the query (CBIR)[5]. Author proposed to use K-means clustering for the classification of feature set obtained from the histogram. Histogram provides a set of features for proposed for Content Based Image Retrieval (CBIR). Hence histogram method further refines the histogram by splitting the pixels in a given bucket into several classes. Computed the similarity for 8 bins and similarity for 16 bins. Standard histograms, because of their efficiency and insensitivity to small changes, are widely used for content based image retrieval. But the main disadvantage of histograms is that many images of different appearances can have similar histograms because histograms provide coarse characterization of an image.

Many problems are solved most readily with recursive algorithms, and recursive algorithms are often shorter and clearer than their iterative counterparts. Recursive algorithm description is typically more elegant and concise than iterative version of the program. The softwares based on recursion are condemned for many years because compilers could not deal efficiently with the overhead of the recursive function call. However, this situation is changing; modern compilers can handle recursion overhead efficiently because of transformation techniques. Performance of computation depends upon construction of compiler, algorithm and hardware design. In this paper authour studied the performance of recursive and iterative programs on two different machines and two different versions of JAVA compiler. It has been observed that the performance of the recursive code is 67% better than iterative version.

Mountains of e-waste discarded parts of computers, mobile phones and other consumer electronics equipment are quietly creating a new environmental problem. E-waste is known to contain dangerous chemical pollutants that are released into the atmosphere and underground water. The modes of disposal, which include dumping old gadgets into landfills or burning in smelters, also expose the environment and humans to a cocktail of toxic chemicals and poison. The world is consuming more and more electronic products every year. As technology evolves, equipment is retired at alarming rate. This has caused a dangerous explosion in electronic scrap containing toxic chemicals and heavy metals that cannot be disposed of or recycled safely. A serious challenge we are facing is that refurbishing and reuse of computers and televisions, while desirable and encouraged, just delays the ultimate disposal problem. The fruits of our high-tech revolution are pure poison if these products are improperly disposed of at the end of their useful life. Discusses various types o substances which are present in electronic scrap and effect of these substances on the environment. Also focus on solutions to reduce electronic wastage.

J Digital Inf Mgmt 2008, 6(4), 338-47.

In the last decade there has been an increasing interest in the use of tools for the creation of geographic maps. However, these tools include functionalities that allow users to insert information without verifying their consistency with the constraints defined by the designer. In this paper we propose an approach based on visual language parsing for guaranteeing the integrity of data produced during the map editing process. According to our approach, constraints are expressed by using high-level data model, such as OMT-G, and converted in a proper visual language grammar automatically. From such a grammar, a parser able to identify incorrect aggregation of spatial data input is generated. The grammar forma/ism also a/lows us to associate suitable semantic actions with productions in order to perform automatic corrections of inconsistent input data, error recognition and visualization, prompting actions for error recovery. We also present a system prototype supporting the proposed process.

If you look up the words agile & chaos together on Google, you'll find that it returns a whopping 819,000 results. This is proof enough for you to understand how chaotic agile could lead to be, if not implemented properly. In order to understand "why does It become chaotic" and "how should it be curbed", we need to first understand the fact that "It's not your project which needs to be tailored to the methodology; it's the methodology which needs to be tailored made to best suite your project". To optimize benefits from agile, it needs to be implemented intelligently. Agile manifesto lays the guidelines which should be adhered to. This does not mean that, you are not allowed to customize the usual set of procedures to best suit your project. Incorrect interpretation and usage of the methodology has a domino effect and at times is solely responsible jeopardizing the project. The primary reason as to why we consider agile methodology to be chaos driven is, because it doesn't allow you make mistakes, yet it expects you to deal with the uncertainties involved. There are multiple ways to deal with upcoming uncertainties. The purpose of this paper is to propose possible solutions by means of customizing the methodology to help you prevent, anticipate and deal with these uncertainties.

Intrusion detection technology is an effective approach to dealing with the problems of network security. Discussion is based on data mining-based network intrusion detection framework in real time (NIDS). This framework is a distributed architecture consisting of sensor, data preprocessor, extractors of features and detectors. To improve efficiency, the approach adopts a novel FP-tree structure and FP-growth mining method to extract features based on FP-tree without candidate generation. FP-growth is just accord with the system of real-time and updating data frequently as NIDS. We employ DARPA intrusion detection evaluation data set to train and test the feasibility of the proposed method. Experimental results show that the performance is efficient and satisfactory. Finally, the development trend of intrusion detection technology and its currently existing problems are briefly given.

Fraud detection involves identifying a fraud as quickly as possible once it has been perpetrated. It requires a tool that is intelligent enough to adapt to criminals' strategies and ever-changing tactics to commit fraud. This paper presents an automated credit card fraud (CCF) detection system based on neural network technology and rule-based component. The Self-Organizing Map (SOM) algorithm was used to create a model of a typical cardholder's behavior and analyze the features of transactions, thus detecting fraudulent transactions. An Artificial Neural Network (ANN) trained with the unsupervised learning method was applied to the data to generate models. An approach was developed to CCF detection that utilizes four clusters (instead of the usual two-stage model normally used in fraud detection algorithms) to reduce the erroneous classification of legitimate transactions as fraudulent and to ensure a more accurate result.

Performance of real-world applications in computer vision and image understanding largely depend on the efficiency of low level tasks involved. One of such low level tasks is the image segmentation process, which is from the combinatorial optimization problem domain. The survey paper emphasizes the recent use and increasing growth of the metaheuristics approach based on natural computing inspired by natural and biological systems for solving the image segmentation specific to various domain-specific applications. The findings of recent studies of such approximate algorithmic approach, largely based on heuristics, to obtain near-optimal solutions are showing strong evidence to the fact that they can be applied to almost all approaches of various image segmentation techniques, such as edge detection, region-oriented, morphological watersheds and clustering. The paper works towards bridging the gap with regard to drawbacks of the state-of-the-art solution of the various segmentation techniques and the available metaheuristic techniques and technologies like particle swarm optimization, Ant Colony Optimization (ACO) and Genetic Algorithms (GA). Finally, it proposes modeling such automated system for learning algorithms based on signals-to-symbol model.

A hybrid prediction model of Artificial Neural Network (ANN) and Rough Set Theory (RST) is proposed in this paper. ANN and RST are frequently applied to different data mining problems. Hybrid approach of combining ANN and RST can be directly applied to classification and regression without additional transformation mechanisms in the data set. ANN is one of the most powerful and universal predictors. On the other hand, the use of RST in knowledge extraction field is proved by the growing number of applications and publications. The main advantage of RST is the non-requirement of prior information about the data for the selection of reduct set. In this paper, a new Rough Neural Network (RNN) algorithm for the proposed hybrid approach in order to predict semen fertility rate is described. This algorithm is composed of two parts namely pre-processing part based on RST and classification part based on ANN. However, there arises an issue of selecting the most significant parameters from the In Vitro Fertility (IVF) tests outcomes. The proposed algorithm examines the substantial discemability between IVF parameters in order to get significant improvement in prediction performance. The improved prediction performance of the proposed algorithm is demonstrated through experiments.

Wavelength Division Multiplexed (WDM) networking technology has been identified as a suitable candidate for future wide area network (WAN) environments, due to its potential ability to meet rising demands of high bandwidth and low latency communication. As traffic demand in the Internet increases exponentially, Wavelength Division Multiplexing (WDM) networks with Terabits per second bandwidth per fiber become a natural choice for the backbone in the future. IP-over-WDM networks i.e. Optical Internets will be the best choice for next generation Internets. Recently, Virtual Topology Reconfiguration of IP-over-WDM networks has received greater attention among researchers. In this paper, we have presented a new analytical approach for traffic modeling and traffic engineering for the next generation internet using IP-over-WDM networks with Quality of Service (QoS) requirements and shown that this new approach achieves better QoS performance in terms of blocking probability, throughput and latency.

On the basis of some algorithm, a search engine decides the rank of the page content and displays the pages in that order, hi the terminology of graph representation of the World Wide Web (WWW), several algorithms based on link analysis have been developed to measure the importance of nodes on a graph such as pages on the WWW. If a node represents page and graph represents the linking among pages (WWW), then PageRank is the most popular ranking algorithm to rank the nodes of any directed graph. The PageRank algorithm has been intuitively justified to model a random surfer in which a user clicks on the links at random and the rank of a page signifies the probability of the user arriving at that page. This algorithm does not consider the time constraint (age of the specific page on the web). It is observed that a number of incoming links which point at a page (with same content) may increase with time because when different persons become aware of the importance of the web page with time, they provide a link to that specific page, thus the number of incoming links to that particular web page may increase with time. Therefore, time must be considered to decide the priority (rank) of the page. Hence time constraint is introduced in the existing algorithm to derive a new and effective algorithm.

Onboard software embedded in flight computers of a Satellite Launch Vehicle has to be of high reliability to meet the stringent requirements for a successful mission. Software defects at any stage affects the quality of software and the stage at which the defect is detected also has an impact on schedule and cost. Elimination of errors as early as possible in the software life cycle is the aim of any Quality Assurance program. Consequently many methods are employed for early detection and elimination of errors. This is achieved through a well-defined development process and thorough verification and validation schemes appropriately applied at all phases of software life cycle. Special precautions like language safe subsets, design features for fault-tolerance and rigorous inspections, static and dynamic analysis are adopted for realizing high reliable software. Static analysis is one technique applied in Launch Vehicle area for early error detection. In this paper the static analysis methods successfully applied for mission critical software are described.

Empirical study shows that many real networks in nature and society share two generic properties: they are scale-free and they display a high degree of clustering. Quite often they are modular in nature also, implying occurrences of several small tightly linked groups which are connected in a hierarchical manner among themselves. Recently, we have introduced a model of spatial scale-free network where nodes pop-up at randomly located positions in the Euclidean space and are connected to one end of the nearest link of the existing network. It has been already argued that the large scale behaviour of this network is like the Barabasi-Albert model. In the present paper we briefly review these results as well as present additional results on the study of non-trivial correlations present in this model which are found to have similar behaviours as in the real-world networks. Moreover, this model naturally possesses the hierarchical characteristics lacked by most of the models of the scale-free networks.

As Knowledge-Based Systems (KBSs) built on hybrid technologies (deductive databases, active databases, constraint databases) gain wider acceptance, there is an increasing need to improve their reliability and quality. Validation and Verification (V&V) of such KBSs is a pre-requisite in the design of complex application software and is distinct from conventional techniques. The objective of the paper is to (a) identify and establish areas of overlap between expert systems and emerging databases systems; (b) identify the possible areas where conventional V&V techniques may be applicable to KBSs; (c) identify V&V techniques that are emerging as a result of evolving nature of KBS; and (d) present issues related to verification, validation, integrity and evaluation in the life cycle of KBS. The paper is directed towards database community with the objective of identifying possibilities where V&V know how may be of value in developing complex application software based on emerging database technologies.

Presents the basic understanding of different intelligent search techniques to find the optimal solution in path finding. As we know that there are many traditional search algorithms like breadth -first search and depth first search used in artificially intelligent applications. But for solving complex problems these will lack in finding the solution within time and space limits. So many special techniques came into existences which are called heuristic functions. Similarly, algorithms that use these techniques are called heuristic algorithms. Thus, intelligent search algorithms are not really intelligent. We call them intelligent because they achieve better performance by applying these techniques than what they would achieve otherwise.

Customer relationship management (CRM), is a term applied to processes implemented by a company to handle its contact with its customers. CRM software is used to support these processes, storing information on current and prospective customers. Information in the system can be accessed and entered by employees in different departments, such as sales, marketing, customer service, training, professional development, performance management, human resource development, and compensation. Details on any customer contacts can also be stored in the system. The rationale behind this approach is to improve services provided directly to customers and to use the information in the system for targeted marketing and sales purposes. While the term is generally used to refer to a software-based approach to handle customer relationships, most CRM software vendors stress that a successful CRM strategy requires a holistic approach. CRM initiatives often fail because implementation was limited to software installation without providing the appropriate motivations for employees to learn, provide input, and take full advantage of the information systems. Why CRM is so important? According to a study in the Harvard Business Review, "increasing customer retention from 10 to 15 percent may double the profits." Moreover, Bain & Company reports that: "It is 10 times more expensive to acquire new customers than to keep existing ones." A fully realized CRM program can not only improve customer loyalty, but can dramatically increase profitability and revenue, while opening new marketing and sales channels and slashing operational costs. The purpose of this document is to provide an overview of some of the key strategies and principles that can help you begin transforming your organization through CRM.

The efforts spent on testing are enormous due to the continuing quest for better software quality, and the ever growing complexity of software systems. The situation is aggravated by the fact that the complexity of testing tends to grow faster than the complexity of the systems being tested, in the worst case even exponentially. Whereas development and construction methods for software allow the building of ever larger and more complex systems, there is a real danger that testing methods cannot keep pace with construction, hence these new systems cannot be sufficiently fast and thoroughly be tested. This may seriously hamper the development of future generations of software systems. One of the new technologies to meet the challenges imposed on software testing is model-based testing. Models can be utilized in many ways throughout the product life-cycle, including: improved quality of specifications, code generation, reliability analysis, and test generation. This paper will focus on the testing benefits from MBT methods and review some of the historical challenges that prevented model based testing and we also try to present the solutions that can overcome these challenges.

Need of ubiquitous computing requires the development of technologies that are pervasive,i.e. omnipresent. Main component of such an environment would be small nodes with sensing capabilities that are able to organize flexibly into a network and are capable of information gathering, processing and communicating. With the technological advancement, it is now a reality. Deployment of small, inexpensive, low-power, distributed devices is now possible. But realizing such a network has several challenges, especially at the protocol & software level. Much initiative is required in the field of communication protocol and data processing. Though the sensor nodes are equipped with a battery for power supply, still their capabilities & functionality are limited. Thus a collaboration is required between nodes to deliver smart services. In the current work we assume a static network that provides a performance degradation in dynamic environments. The hew technology requires reconfigurable sensor nodes that are self-configurable and autonomous.

Mobile Ad-Hoc Network (MANET) is a multihop wireless network formed by a collection of mobile nodes wherein the nodes move arbitrarily thus making the topology dynamic. MANETs have low bandwidth wireless links hence the routing protocols with less consumption of bandwidth are of great importance. This paper presents a new hybrid routing algorithm with efficient utilization of bandwidth by restraining the transmission of routing related messages called Bandwidth Efficient Location Aware Hybrid Routing Algorithm (BELAHR). Algorithm uses the physical location of the mobile nodes and also different mechanisms are used by the algorithm to reduce the transmission of route search messages in the whole network. Route search messages are routed only through limited nodes using the physical locations of the nodes therefore reduces the latency in path convergence. Algorithm encourages the route stability by employing preventive maintenance and local repairs of the routes that leads to saving the limited energy of the anemic mobile nodes and hence utilizes the bandwidth optimally which is a very crucial resource of wireless networks.

Knowledge is indispensable in everyday work. Everyone has an idea of the way in which he can carry out his work and this knowledge can be used again and again as and when required according to different tasks and different situations. The general purpose of Knowledge Management (KM) is to make knowledge usable for more than one individual, e.g. for an organization as a whole; that is, to share it. New knowledge-based views on organizations suggest that it is the knowledge that holds organizations together. This paper does not considers the difference between information and knowledge simply, but considers deeply the power or ability to convert from one form of knowledge to another, which is the ability to understand and learn things, or the ability to think and understand things instinctively or automatically.

Computer network technology produces benefits on several fields within the organization, between the organizations (sub-organizations) or among different organizations (sub-organizations). Network technology streamlines business processes, decision process. Graphs are useful data structures capable of efficiently representing a variety of networks in the various fields. Metagraph is a like graph theoretic construct introduced recently by Basu and Blanning in which there is set to set mapping in place of node to node as in a conventional graph structure. Metagraph is thus a new type of data structure occupying its popularity among the computer scientists very fast. Every graph is special case of Metagraph. In this paper the authors introduce the notion of Meta-network Graphs Topologies for Computer Epidemiologists (MNGTCE). MNGTCE as a new network technological representation, which is having all the capabilities of crisp network as well as few additional capabilities. It is expected that the notion of meta-networking will have huge applications in due course. This paper play the role of introducing this new concept to the network technologists and scientists.

Quantum cryptography is an approach to securing communications by applying the phenomena of quantum physics. Unlike traditional classical cryptography, which uses mathematical techniques to restrict eavesdroppers, quantum cryptography is focused on the physics of information. Quantum cryptography provides secure communication, whose security depends only on the validity of quantum theory, i.e., it is guarantied directly by the laws of physics. This is a substantial difference from any classical cryptographic techniques. This article summarizes the current state of quantum cryptography and provides potential extensions of its feasibility as a mechanism for securing existing communication systems.
