There are so many methods and implementations for developing a secured communication with the users that our located within the security domain. Now days as technologies and number of users is increasing day by day we need to provide high secure for each and every new established connection. But the problem arises when any new communication is established outside the security domain. To avoid this problem, investigates the requirements, technologies and risk mitigation techniques for securely sharing information with the tactical user. The new enterprise architecture needs to eliminate the stovepipe architectures and open the doors to share information across traditional and non-traditional domain boundaries.

Mobile Adhoc networks are rapidly deployable and self-configuring networks. There is no need for existing infrastructure. These are wireless links. In this network nodes are mobile, topology can be very dynamic. Here the nodes must be able to relay traffic since communicating nodes might be out of range. A MANET can be a standalone network or it can be connected to external networks (Internet). The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Its routing protocol has to be able to cope with the new challenges that a MANET creates such as nodes mobility, security maintenance, and quality of service, limited bandwidth and limited power supply. These challenges set new demands on MANET routing protocols. The main objective is to compare the performance based on jitter present in transmission of packet in a MANET by using different types of protocols viz: Proactive, Reactive, Hybrid. This system is developed for IEEE 802.11b based Wireless network and simulated through Qualnet 5.0. Packet size and No. of users are the two parameters in this paper which helps to find out the suitable type of traffic that can be use in a MANET.

Web pages are returned in response to a web user query on the search interface of a search engine. Search engines, for the same, use some algorithms so as to bring an ordering among the web pages to be returned to the user in response. Such algorithms are named "Page Ranking Algorithms". Many of these algorithms exist in practice and are in use by a couple of search engines as the literature dictates. A detailed comparison study is being performed on three of such algorithms: first is the Page Rank, the Google's algorithm; second, the Weighted Page Rank, an extension to the first one and the last being the PRLV (Page Ranking based on Link Visits), which works on the pattern of Page Rank and takes number of visits of inbound links of Web pages into account.

Mining web access sequences (WASs) can discover very useful knowledge from web logs with broad applications. By considering non-binary occurrences of web pages as internal utilities in WASs, e.g., time spent by each user in a web page, more realistic information can be extracted. However, the existing utility-based approach has many limitations such as considering only forward references of web access sequences, not applicable for incremental mining, suffers in the level-wise candidate generation-and-test methodology, needs several database scans and does not show how to mine web access sequences with different impacts/significances for different web pages. In this paper, we propose a novel framework to solve these problems. Moreover, we propose two new tree structures, called utility-based WAS tree (UWAS-tree) and incremental UWAS-tree (ILWAS-tree) for mining WASs in static and incremental databases, respectively. Our approach can handle both forward and backward references, static and incremental data, avoids the level-wise candidate generation-and-test methodology, does not scan databases several times, and considers both internal and external utilities of a web page. The IUWAS-tree is also applicable for interactive mining. Extensive performance analyses show that our approach is very efficient for both static and incremental mining of high utility WASs.

This paper presents an optimal technique for image compression by which one can achieve maximal storage and transmission capabilities. Realizing image compression hardware into a Field Programmable Gate Array (FPGA) reduces the implementation cost as well as the prototyping and design time cycle. Aggressive algorithm to architecture mapping of a Quad Tree based image compression method produces a fast, compact pipelined design. Mapped into a Xilinx Spartan II, XC200S-5PQ208 FPGA, this design utilizes as much as half the resources that other algorithms such as Discrete Cosine Transform and Wavelet Transform use. Performance of this implementation exceeds those of similar and or greater resource size, and allows for real-time image compression of an image up to 256 pixels by 256 pixels at 256 levels of gray. It is found that the algorithm provides a high compression ratio ranging between 0.12 and 0.68.

High-level synthesis (HLS) has emerged as the most sophisticated way to bridge the gap between electronic system level (ESL) and its respective structural building block at the register transfer level (RTL). As the growth of system complexity rapidly increases, the gap between high level and RTL needs to be filled. Much advancement has been made in the area of HLS, but none of the works have focused on a formal design methodology that bridges the gap from ESL to RTL considering multi-parametric optimization requirements. This paper exclusively focuses on the formal steps required for multi-parametric optimized HLS design flow. This is significant for industrial projects as well as for the development of fully automated HLS tools for the current generation of portable devices and high-end applications. The design flow initiates with the mathematical model of the application, performs multi-objective design space exploration and finally shows all the steps necessary after exploration for the HLS design. This paper explicitly focuses on highlighting the design flow with optimization of three parameters area, execution time and power consumption during HLS design while working under the prerequisite of stringent operational constraints. The implementation of the proposed method on Field-programmable Gate Array and the chip layout generation will also be presented.

In this paper an attempt has been made to detect the face using the combination of integral image along with the cascade structured classifier which is built using Adaboost learning algorithm. The detected faces are then passed through a filtering process for discarding the non face regions. They are individually split up into five segments consisting of forehead, eyes, nose, mouth and chin. Each segment is considered as a separate image and Eigenface also called principal component analysis (PCA) features of each segment is computed. The faces having a slight pose are also aligned for proper segmentation. The test image is also segmented similarly and its PCA features are found. The segmental Euclidean distance classifier is used for matching the test image with the stored one. The success rate comes out to be 88 per cent on the CG database created from the databases of California Institute and Georgia Institute. However the performance of this approach on ORL database with the same features is only 70 per cent. For the sake of comparison, discrete cosine transform (DCT) and fuzzy features are tried on CG and ORL databases but using a well known classifier, support vector machine (SVM). Results of recognition rate with DCT features on SVM classifier are increased by 3 per cent over those due to PCA features and Euclidean distance classifier on the CG database. The results of recognition are improved to 96 per cent with fuzzy features on ORL database with SVM.

High quality graphics for game characters has been continuously improving, spurred by the astonishing growth of the graphics technology. Despite such improvements, the current expression of emotion has limited representation because it is difficult to implement it in real-time and a large amount of storage is required to store sprites for various feelings. Since users are demanding a more expressive character to reflect emotion, such restrictions can prevent the users from getting fully indulged in a game. To address this, we propose a facial color transition model, which is a combination of the emotional colors based on the theory of emotion, the emotion-color association, and the emotional transition with personal traits. The model is implemented by using the homeostatic value, the accumulated stimulus, and nonlinear transition functions, which support diverse changes according to the character's personality with low computational cost. The reflection of the game character's emotion on its facial color will not only make users immerse into the game, but also enrich their fantasy in games.

Content-based image retrieval focuses on intuitive and efficient methods for retrieving images from databases based on the content of the images. A new entropy function that serves as a measure of information content in an image termed as 'an information theoretic measure' is devised in this paper. Among the various query paradigms, query by example (QBE) is adopted to set a query image for retrieval from a large image database. In this paper, colour and texture features are extracted using the new entropy function and the dominant colour is considered as a visual feature for a particular set of images. Thus colour and texture features constitute the two-dimensional feature vector for indexing the images. The low dimensionality of the feature vector speeds up the atomic query. Indices in a large database system help retrieve the images relevant to the query image without looking at every image in the database. The entropy values of colour and texture and the dominant colour are considered for measuring the similarity. The utility of the proposed image retrieval system based on the information theoretic measures is demonstrated on a benchmark dataset.

Automatic extraction of vessel centerlines is viewed as an essential process in majority of image-guided diagnostic and therapeutic applications. Among a considerable number of methods, direct exploratory tracing method is known as an efficient solution for reliable extraction of vessel features from two-dimensional fluoroscopic images. The first step of most automatic exploratory tracing algorithms is to collect some candidate initial seed points as well as their initial tracing directions. To detect reliable initial points, a validation procedure is required to filter out the false candidates and avoid unnecessary tracing. Starting from reliable initial points, the algorithm efficiently extracts the centerline points along the initial direction until certain pre-defined criteria are met. However, most of these algorithms suffer from incomplete results due to inappropriate selection of the initial seed points. The conventional seed point selection algorithms either rely merely on signal-to-noise ratio analysis, which results in a large number of false traces, or impose a set of strict geometrical validation rules which leads to more false negatives and as a consequence more time shall be spent on computation. This paper presents a new method for efficient selection of initial points for exploratory tracing algorithms. The proposed method improves the performance upon existing methods by employing a combination of geometrical and intensity-based approaches. Moreover, it provides a tunable trade-off between the strictness of the validation procedure and computational efficiency. The results of comparative performance with other proposed techniques are included.

Importance of development and up-gradation of existing highway infrastructure in the country has been greatly acknowledged during the last decade and serious efforts are being made to this end, both by the Central and the State Governments. The parameter, almost universally used to characterize soils for the purposes of pavement design, is the California Bearing Ratio. Many attempts have been made to correlate the CBR with the soil properties to obviate laboratory testing. The laboratory tests to determine CBR are expensive and time consuming with adverse bearing on the preparation of the Detailed Project Reports. An attempt has been made in this paper to develop an Artificial Neural Network (ANN) model to determine reasonably accurate CBR, based on the simpler laboratory tests for grading and Atterberg limits of the soil. Data used in the training and testing of the model was collected from some soil samples tested by the author and additionally from tests got conducted by various Madhya Pradesh State entities undertaking the development of highways in the State. Back Propagation Neural Network is used for function approximation and the model has been trained by Lavenberg-Marqurdt learning algorithm. Test results achieved in the model demonstrate that the CBR can be predicted to a reasonable degree of accuracy. Use of an ANN model can thus greatly reduce the cost and time involved in the design of pavements.

Virtualization technologies changed the way data centers of enterprises utilize their server resources. Instead of using dedicated servers for each type of application, virtualization allows viewing resources as a pool of unified resources, thereby reducing complexity and easing manageability. Server consolidation technique, which deals with reducing the number of servers used by consolidating applications, is one of the main applications of virtualization in data centers. The latter technique helps to use computing resources more effectively and has many benefits, such as reducing costs of power, cooling and, hence, contributes to the Green IT initiative. In a dynamic data center environment, where applications encapsulated as virtual machines are mapped to and released from the nodes frequently, reducing the number of server nodes used can be achieved by migrating applications without stopping their services, the technology known as live migration. However, live migration is a costly operation; hence, how to perform periodic server consolidation operation in a migration-aware way is a challenging task. We propose server consolidation algorithm - Sercon, which not only minimizes the overall number of used servers, but also minimizes the number of migrations. We verify the feasibility of our algorithm along with showing its scalability by conducting experiments with eight different test cases.

Utility mining has recently been an emerging topic in the field of data mining. It finds out high-utility itemsets by considering both the profits and quantities of items in transactions. In real applications, however, utility mining may have a bias if items are not always on shelf. On-shelf utility mining is then proposed, which considers not only individual profit and quantity of each item in a transaction but also common on-shelf time periods of a product combination. In the past, a two-phase on-shelf utility mining was proposed to discover the desired patterns in on-shelf utility mining. It, however, adopted the level-wise mining way to find the patterns. To speed up the execution efficiency, a three-scan mining approach is thus proposed in the paper to efficiently discover high on-shelf utility itemsets. The proposed approach utilizes an itemset-generation mechanism to prune redundant candidates early and to systematically check the itemsets from transactions. At last, the experimental results on synthetic datasets show the proposed approach has a better performance than the previous one.

Wireless sensor networks (WSNs) do not have a fixed infrastructure and consist of sensor nodes that perform sensing and communicating tasks. The WSNs have large application spectrum such as habitat monitoring, military surveillance, and target tracking, where sensor nodes may operate distributed in highly dynamic environments. Battery-constrained sensor nodes may aggregate the sensed data, localize themselves, and route the packets in an energy-efficient and decentralized manner to enable running the applications. Agents are capable of independent and autonomous action, so that they can successfully carry out tasks that have been delegated to them, thus agent-based approaches are very suitable to apply as the solution of the problems occurring in WSNs. So far many agent-based approaches were proposed for WSNs. This paper surveys the agent technologies for sensor networks by providing a classification, objectives and costs of these approaches with the open research problems. To the best of our knowledge, this is the first study that covers the intersection of the agent technology and sensor networks from a wide perspective.

Software development productivity and product quality are related to quality of the software development process. Therefore, if we can improve quality of software development process based on project management technologies, software development productivity and product quality will be increased. In this paper, we conduct a multivariate analysis by using process measurement data, and derive a relational expression based on statistically significant factors, which can quantitatively predict final product quality/reliability. Furthermore, we apply a method of collaborative filtering by using process measurement data to predict final product quality from the similarity of software projects. Finally, we compare the results of two methods, i.e., multiple regression analysis and collaborative filtering, in terms of predictive accuracy of final product quality/reliability.

In this paper, new schemes are proposed that generate large random Quasigroups based on a user passnvord. Encryption is carried out in two steps. First, a pseudo-message is generated using a Quasigroup based All or Nothing Transform (AONT). Next, this message is encrypted either by a Quasigroup string transformation or by using a computationally efficient cryptographic scheme. To further increase the security of the scheme, the cipher output is processed using single-cycle invertible functions. Analysis has been carried out using similar as well as different text messages and keys for Quasigroup of order up to 256. The schemes have been found to be resistant to many existing statistical attacks. The schemes also depict the avalanche property which has been tested by introducing minor changes in the key and plaintext message. Observations and results show that these schemes are both secure and efficient and can be used for normal as vell as resource constrained environments.

The design of Control and Instrumentation (C & I) systems used in safety critical applications such as nuclear power plants involves partitioning of the overall system functionality into subparts and implementing each subpart in hardware and/or software as appropriate. With increasing use of programmable devices like FPGA, the hardware subsystems are often implemented in Hardware Description Languages (HDL) like VHDL. Since the functional bugs in such hardware subsystems used in safety critical C&I systems have disastrous consequences, it is important to use rigorous reasoning to verify the functionalities of the HDL models. We describe our work on developing a software tool named VBMC (VHDL Bounded Model Checker) for mathematically proving functional properties of hardware designs described in VHDL. It is based on the principle of bounded model checking. Although the design of VBMC is still evolving, it is currently also being used for the functional verification of FPGA based intelligent I/O (EHS) boards developed in Reactor Control Division, BARC.

With the availability of massive computting power, there has been a resurgence of mutation analysis within computer science community, and work has been done to define the methods of applying mutation testing on Object Oriented Programs. Mutation testing is an important fault based testing technique. The primary use of mutation testing is in determining the effectiveness of test suites and to mak them more effective for detecting certain types of bug. The effectiveness of mutation testing depends heavily on the type of faults that the mutation operators are designed to introduce. This paper is concerned to detect a difference in the output produced as a part of mutation analysis. The checker in the test bench will actually detected the difference to measure the performance of mutation testing.

This study reports on improvements made to the phoneme matching algorithm (PMA) the PMA's purpose is to identify word recognition errors in automatically generated transcripts detailing the speech content of digital multimedia soundtracks. When utilising these speech transcripts as a means of searching for a specific segment (clip) within an audiovisual document, it has been observed that even professional researchers tend to underestimate the fallibility of the automatic speech recognition (ASR) technology used to produce these automatic speech-to-text transcriptions. As demonstrated by two of the user evaluation studies reported here, it is usually the case that users - when searching a transcript for some key word or phrase - will, if the transcript does not contain the query term, neglect to conduct a systematic auditory inspection of the corresponding multimedia document's soundtrack, even though such a careful 'listen-through' would be the usual procedure if speech transcriptions were not available. In order, therefore, to alert the user to the possibility that a particular search term may have been incorrectly recognised as some other word or phrase, the PMA - when invoked during a query operation - will parse the transcript's text to locate words or phrases of similar phonetic structure to the query term and present these suspected ASR errors to the user for consideration. When tested on a corpus of digital multimedia documents the improved PMA averaged a 73.64% success rate in correctly identifying words/phrases which were actually instances of misrecognised query terms.

This paper discusses the application of neural networks for developing different speech systems. Prosodic parameters of speech at syllable level depend on positional, contextual and phonological features of the syllables. In this paper, neural networks are explored to model the prosodic parameters of the syllables from their positional, contextual and phonological features. The prosodic parameters considered in this work are duration and sequence of pitch (F0) values of the syllables. These prosody models are further examined for applications such as text to speech synthesis, speech recognition, speaker recognition and language identification. Neural network models in voice conversion system are explored for capturing the mapping functions between source and target speakers at source, system and prosodic levels. We have also used neural network models for characterizing the emotions present in speech. For identification of dialects in Hindi, neural network models are used to capture the dialect specific information from spectral and prosodic features of speech.

Libraries have to adapt to changing times having a digital library with e-books for which FOSS is needful for every day applications in a library. Free and Open-source software (FOSS) is computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that meets the Open Source Definition or that is in the public domain. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified forms. It is very often developed in a public, collaborative manner. Open-source software is the most prominent example of open-source development and often compared to user-generated content. The term open-source software originated as part of a marketing campaign for free software. A report by Standish Group states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers.

Mobile ad hoc networks (MANETs) are a kind of network that has no centralized body and in order to communicate with the nodes it has no fixed topology. Also it is difficult to find the route from source to destination in MANETs, because of its arbitrary mobility of nodes. In FRENSA (Farthest Reliable Efficient Node Selection Algorithm) we have discussed that how we can select a node that can act as a gateway to the other regions and a path from source to destination that should be efficient and reliable too. In this paper we are going to show that how FRENSA works with the three different cases (i.e. Best, Average and Worst) for selecting a path and can check the reliability and efficiency of route and can also check the complexity of route in terms of hopes in distance. In all the cases we would take some parameters that have been used in FRENSA and analyze the performance of this algorithm in all the cases.

All these activities are inspected and tested. During the SDLC these are categorised as how to perform them, they are actually performed or not, is checked in the testing section. It is not the testing phase which will check the system. Testing start at the earlier stage of SDLC from the information gathering. Software testing is categorized into different types. One of the main purposes of categorizing software testing is to identify faults in the software. Faults in software testing can be defined as conflict from requirement or user expectation. It is very easy to categorize faults. If system is not functioning properly, it is a functional defect. If system is not performing well, it is a performance defect. If system is not usable, it is a usability defect. If system is not secure, it is a security defect. To identify these different faults, different skill set, different techniques and different type of test cases are required. Testing is divided into different types to reflect, what kind of faults can be uncovered by those activities. This division also helps management in managing these activities effectively. There is a very rare to have someone with skills in all the types of testing and this division helps in getting proper resources for team. Author tried to categorized the software testing test so that they may help to identifying the fault to uncovered it by those activities.

Modern day telecommunication industry is facing ever increasing demand for more sophisticated services, higher quality and shorter times to market. Network operators and service providers in the telecommunications industry must meet these demands at a commercially viable cost and should have plans in place for any unforeseen change. Current management models based on client/server suffer from scalability and flexibility problems. Furthermore, the staleness of gathered data (due to network latency involved) and probable error in the selection of management task being carried over (owing to the staleness of data) reduces the reliability of the management applications. A distributed paradigm is a viable solution to perform management functions when network start growing significantly. It offers decentralize processing and control thereby reducing the management traffic around the management station and distribute processing load. In this sense, use of mobile agents offer many possibilities for designing the next generation of distributed network management systems. Discusses various mobile agent based network management models and analyzes the key advantages of mobile agents in the distributed network management systems.

Client server setup has servers, which are dedicated machines that perform specific functions in the network. A server can be used to manage a network's email, database, files, printers, or access an anti-virus. In a client server setup, each component has a designated function in the network. One server generally supports numerous clients, and multiple servers can be networked together in a pool to handle the increased processing load as the number of clients grows. A client computer and a server computer are usually two separate devices, each customized for their designed purpose. However, in some cases a given device can function both as a client and a server for the same application. With a client-server approach, the performance of the server will deteriorate as the number of clients requesting services from the server increase. There is a scalability problem.
