The increasing popularity of web-based applications has led to several critical services being provided over the Internet. This has made it imperative to monitor the network traffic so as to prevent malicious attackers from depleting the resources of the network and denying services to legitimate users. This paper has presented a mechanism for protecting a web-server against a distributed denial of service (DDoS) attack. Incoming traffic to the server is continuously monitored and any abnormal rise in the inbound traffic is immediately detected. The detection algorithm is based on a statistical analysis of the inbound traffic on the server and a robust hypothesis testing framework. While the detection process is on, the sessions from the legitimate sources are not disrupted and the load on the server is restored to the normal level by blocking the traffic from the attacking sources. To cater to different scenarios, the detection algorithm has various modules with varying level of co...

The present paper discusses the problem of estimating the finite population mean in simple random sampling. A class of estimators has been proposed using information on an auxiliary variable and its properties are studied. It has been shown that the proposed class of estimators is more efficient than the usual unbiased, ratio and product estimators. An empirical study has been carried out to examine the merits of the proposed class of estimators over others.

Horizontally overlapping lines are normally found in printed newspapers of any Indian script. Along with these overlapping lines few other broken components of a line (strip) having text less than a complete line are also found in text. The horizontally overlapping lines and other strips make it very difficult to estimate the boundary of a line leading to incorrect line segmentation. Incorrect line segmentation decreases the recognition accuracy. In this paper we have proposed a solution for segmenting horizontally overlapping lines and solved the problem of other strips in eight most widely used printed Indian scripts. Whole document has been divided into strips and proposed algorithm has been applied for segmenting horizontally overlapping lines and associating small strips to their respective lines. The algorithm has shown approximately 96.45-99.79% accuracy depending upon script. We have also tried to segment horizontally overlapping lines, containing different sized text, i.e. the newspaper articles in which bigger sized heading lines overlaps with normal sized text lines.

In ant societies, and, more in general, in insect societies, the activities of the individuals, as well as of the society as a whole, are not regulated by any explicit form of centralized control. On the other hand, adaptive and robust behaviors transcending the behavioral repertoire of the single individual can be easily observed at society level. These complex global behaviors are the result of self-organizing dynamics driven by local interactions and communications among a number of relatively simple individuals. The simultaneous presence of these and other fascinating and unique characteristics have made ant societies an attractive and inspiring model for building new algorithms and new multi-agent systems. In the last decade, ant societies have been taken as a reference for an ever growing body of scientific work, mostly in the fields of robotics, operations research, and telecommunications.

In content-based image retrieval (CBIR), content of an image can be expressed in terms of different features such as color, texture, and shape. In this paper, the color information of an image is represented by the Global HSV Color Histogram. The texture information is described by the variance of each wavelet subband in compressed domain with the emphasis that subbands are not buffered to maintain memory efficiency. In addition, the Gabor Filter has been used also to extract the texture features. The Edge Detection is represented here by the Edge Direction Histogram. The shape information is represented by the Zernike Moment Descriptor (ZMD). The image retrieval is indexed by both individual features and combined image features. A Java-based retrieval framework has been developed to conduct the online retrieval framework to compare the retrieval performance and speed. Experiments are performed with 52 texture patterns and different similarity measures over the VisTex database. The experimental results show that the image retrieval using combined features outperforms retrieval using individual features.

In digital electronics, the power dissipation is the major problem. So that the reversible gate can be implemented in microelectronics and electronics which have low power dissipation in the digital designing because, in the reversible state in reversible logic it will use no energy. Hence reversible logic has ability to reduce the power dissipation in digital designing. In the Reversible logic, reversibility have a special condition which is reversible computing and reversible computing is based on the principle of BIJECTION DEVICE with a same no. of input and output which means one to one mapping. Reversible logic has numerous applications in the field of electronics and microelectronics which are ultra low power in nanoscale computing, quantum computing, emerging nanotechnology cellular automata and the other approach of reversible logic is ballistic computation, mechanical computation which are the basic technology. This paper presents an optimization of reversible comparator using the existing reversible gates and proposed new Reversible one bit comparator using BVF gate. A comparative result is presented in terms of number of gates, number of garbage outputs, number of constant inputs and Quantum cost.

In this paper Advanced Encryption Standard (AES) algorithm has been designed and implemented as custom hardware. The algorithm is controlled through C-code written in NIOS II IDE. AES as a custom hardware is interfaced with the system designed around NIOS II Processor using SOPC builder tool. AES is written in hardware in VHDL language and the interface is through GPIO (General Purpose Input / Output Port). AES implemented using data size of 128 bits, while the length of the key used is of 128 bits. The key size of AES used is of 128 bits, as it is secure from the different attacks in existence. The FPGA used is CYCLONE II from Altera. AES as a custom hardware increases the speed of encryption and serves as an accelerator and hence improves the performance of the system.

Distributed, event based applications executing on publishsubscribe middleware (aka Event Based Middleware or EBM) are subject to many disruptive changes at runtime. These changes can be caused either by a change in environmental conditions such as the failure of an event broker node or can be caused by dynamically evolving application needs such as the sudden need to route events securely from a specific publisher to a set of subscribers. Ideally, the middleware should facilitate uninterrupted execution of applications without costly redeployment in the face of these changes. We formally study the requirements of such an "adaptive" middleware infrastructure and analyze adaptation in existing efforts. An adaptive overlay for a core level adaptive middleware with a chordal reliability ring is proposed on the basis of the study. We illustrate and prove that two of the adaptation triggers -node and link failures can be handled by the middleware in O (log n) time with the help of the chordal reliability ring.

In ant societies, and, more in general, in insect societies, the activities of the individuals, as well as of the society as a whole, are not regulated by any explicit form of centralized control. On the other hand, adaptive and robust behaviors transcending the behavioral repertoire of the single individual can be easily observed at society level. These complex global behaviors are the result of self-organizing dynamics driven by local interactions and communications among a number of relatively simple individuals. The simultaneous presence of these and other fascinating and unique characteristics have made ant societies an attractive and inspiring model for building new algorithms and new multi-agent systems. In the last decade, ant societies have been taken as a reference for an ever growing body of scientific work, mostly in the fields of robotics, operations research, and telecommunications. Among the different works inspired by ant colonies, the Ant Colony Optimization metaheuristic (ACO) is probably the most successful and popular one. The ACO metaheuristic is a multi-agent framework for combinatorial optimization whose main components are: a set of ant-like agents, the use of memory and of stochastic decisions, and strategies of collective and distributed learning. It finds its roots in the experimental observation of a specific foraging behavior of some ant colonies that, under appropriate conditions, are able to select the shortest path among few possible paths connecting their nest to a food site. The pheromone, a volatile chemical substance laid on the ground by the ants while walking and affecting in turn their moving decisions according to its local intensity, is the mediator of this behavior. All the elements playing an essential role in the ant colony foraging behavior were understood, thoroughly reverse-engineered and put to work to solve problems of combinatorial optimization by Marco Dorigo and his co-workers at the beginning of the 1990's. From that moment on it has been a flourishing of new combinatorial optimization algorithms designed after the first algorithms of Dorigo's et al., and of related scientific events. In 1999 the ACO metaheuristic was defined by Dorigo, Di Caro and Gambardella with the purpose of providing a common framework for describing and analyzing all these algorithms inspired by the same ant colony behavior and by the same common process of reverse-engineering of this behavior. Therefore, the ACO metaheuristic was defined a posteriori, as the result of a synthesis effort effectuated on the study of the characteristics of all these ant-inspired algorithms and on the abstraction of their common traits. The ACO's synthesis was also motivated by the usually good performance shown by the algorithms (e.g., for several important combinatorial problems like the quadratic assignment, vehicle routing and job shop scheduling, ACO implementations have outperformed state-of-the-art algorithms). The definition and study of the ACO metaheuristic is one of the two fundamental goals of the thesis. The other one, strictly related to this former one, consists in the design, implementation, and testing of ACO instances for problems of adaptive routing in telecommunication networks. This thesis is an in-depth journey through the ACO metaheuristic, during which we have (re)defined ACO and tried to get a clear understanding of its potentialities, limits, and relationships with other frameworks and with its biological background. The thesis takes into account all the developments that have followed the original 1999's definition, and provides a formal and comprehensive systematization of the subject, as well as an up-to-date and quite comprehensive review of current applications. We have also identified in dynamic problems in telecommuni-First, I shall thank the ants! Without those little mates bugging around this thesis simply would have not happened. When I was a little kid, I was kind of concerned about the little ant-hills and their tiny inhabitants sprouting all over my garden. So, one day, I started thinking that during the winter they could feel cold, and I unilaterally decided to equip their primitive nests with a technologically advanced heating system. Therefore, I started drilling and putting pipes underground, connecting the pipes to faucets and sinks, and letting hot water passing through in order to warm up my little mates during the cold winter days. How disappointed I was when I realized that they didn't appreciate my heating technology and quite in a short time they just vanished, likely moving their nests somewhere else! Well, actually, I then tried to let my adorable cat to enjoy my concerns about cold and I brought my now well consolidated heating technology into the carton box where he was used to spend, sleeping, most of his precious time. Unfortunately, he too didn't seem ready to enjoy the pleasures of technology, so I gave up and focused on other amenities.. . So, I do really feel now that in a sense my little mates had actually appreciated those maybe a bit awkward efforts and rewarded me back, laying somewhere in the universe the pheromone trail that led me to Marco Dorigo and his ant-inspired algorithms. He's the person I shall thank the more for what is in this thesis, and for really bugging me to write it! The content of the thesis covers part of the research work that I've done during the last six years. These years have been a long journey into science and into life. I've moved first to Brussels (IRIDIA), then to Japan (ATR), then back to Belgium (IRIDIA again), and finally to Lugano, in Switzerland (IDSIA). All these places have been great places to work and enjoy life. They are fully international environments where I had the chance to make really good friends and to meet so many great scientists from whom I could really learn so much! I want to thank for this the directors of these laboratories where I have been (Philippe Smets, Hugues Bersini and Marco Dorigo, Katsunori Shimohara, Kenji Doya, and Luca Gambardella) who have done and are still doing a great job! This thesis is really the outgrowth of all the discussions, brainstorming, collaborations, that have happened during these years. It's like a puzzle, whose tiles have been added day by day: after a discussion in front of several beers, or after attending a seminar about how Japanese can learn to distinguish between the sounds "lock" and "rock", or after a long telephone call with some friend thousands of kilometers far away discussing about markov decision processes or antibodies at 3am.. . Thinking back, I realize that I should thank so many people across the world, but they are really too many. I want to mention here just few of them, those who consciously or unconsciously (!), in different ways, have had a major impact on my growth as a scientist. The list is in (stochastic)

Security/privacy issues are of paramount importance for widespread acceptance and use of RFID tags. Over the past few years, researchers have addressed this issue through lightweight cryptographic means. A majority of existing literature in this area consider communication between a single-tagged object and a single reader or owner of this tag. There are instances where either or both of these may not be valid. For example, an object could have multiple disparate embedded tags in each of its component parts or several identical tags could have been affixed to this object for improving its read rate accuracy. Similarly, several readers (or, owners) may simultaneously have the necessary privilege, keys, etc. to be able to read (or, own) a tagged object as happens with vendor management inventory. In the multiple-tagged object scenario, objects gain and lose tags over time as components are added or removed from the object of interest. We consider the multiple-tagged object scenario and present cryptographic protocols for tag updates. We then present ownership transfer protocols for the multiple-tagged object scenario. We also provide a brief security analysis of the presented protocols.

Integration testing of Complex Embedded systems (CES) and associated interconnection network has not been discussed much in the literature. This paper focuses on integration testing among Embedded Processing Components (EPCs) that are (loosely coupled) interconnected via I/O ports. This paper models EPC as a deterministic FSM and describes its fault model that captures errors in the interface between the Hardware and software. The EPC integration with rest of ES (or another EPC) can be viewed as a system under test (SUT) composed of two parts: EPC1 that requires integration testing with the other EPC2. This paper models EPC integration testing as a general fault localization problem between Communicating FSM. An example shows that the integration testing of two subsystems is a subset of general fault diagnostic problem and the faulty machine can be identified during integration.

The finite cell method (FCM) belongs to the class of immersed boundary methods, and combines the fictitious domain approach with high-order approximation, adaptive integration and weak imposition of unfitted Dirichlet boundary conditions. For the analysis of complex geometries, it circumvents expensive and potentially error-prone meshing procedures, while maintaining high rates of convergence. The present contribution provides an overview of recent accomplishments in the FCM with applications in structural mechanics. First, we review the basic components of the technology using the p-and B-spline versions of the FCM. Second, we illustrate the typical solution behavior for linear elasticity in 1D. Third, we show that it is straightforward to extend the FCM to nonlinear elasticity. We also outline that the FCM can be extended to applications beyond structural mechanics, such as transport processes in porous media. Finally, we demonstrate the benefits of the FCM with two application examples, i.e. the vibration analysis of a ship propeller described by T-spline CAD surfaces and the nonlinear compression test of a CT-based metal foam.

Wireless capsule endoscopy (WCE) is relatively a new device which investigates the entire gastrointestinal (GI). About 55000 frames are captured during an examination (two frames per second). Thus, it is bene icial to ind an automatic method to detect diseases frames or regions of a frame. The WCE videos have lots of uninformative regions (such as intestinal juice, bubbled, and dark regions); therefore, preprocessing is useful and necessary in diseases detection. In this paper, three practical methods are introduced to detect the informative and uninformative regions in a frame. In order to achieve this goal, morphological operations, fuzzy k-means, sigmoid function, statistic features, Gabor ilters, Fisher test, neural network, and discriminators in the HSV color space are used to detect uninformative regions (do not carry clinical information) in a frame. Our experimental results indicate that precision, sensitivity, accuracy, and speci icity are respectively 97.76%, 97.80%, 98.15%, and 98.40% in the irst method, 93.32%, 84.60%, 91.05%, and 95.67%, respectively in the second one, and 93.32%, 84.60%, 91.05%, and 95.67%, respectively in the third method.

The focus of this work is to provide authentication and confidentiality of messages in a swift and cost effective manner to suit the fast growing Internet applications. A nested hash function with lower computational and storage demands is designed with a view to providing authentication as also to encrypt the message as well as the hash code using a fast stream cipher MAJE4 with a variable key size of 128-bit or 256-bit for achieving confidentiality. Both nested Hash function and MAJE4 stream cipher algorithm use primitive computational operators commonly found in microprocessors; this makes the method simple and fast to implement both in hardware and software. Since the memory requirement is less, it can be used for handheld devices for security purposes.

AI-based security systems utilize big data and powerful machine learning algorithms to automate the security management task. The case study methodology is used to examine the effectiveness of AI-enabled security solutions. The result shows that compared with the signature-based system, AI-supported security applications are efficient, accurate, and reliable. This is because the systems are capable of reviewing and correlating large volumes of data to facilitate the detection and response to threats.

In the domain of image processing, face recognition is one of the most well-known research field. When humans have very similar biometric properties, such as identical twins, the face recognition system is considered as a challengeable problem. In this paper, the AdaBoost method is utilized to detect the facial area of input image. After that the facial area is divided into some local regions. Finally, new efficient facial-based identical twins feature extractor based on the geometric moment is applied into local regions of face image. The used feature extractor is Pseudo-Zernike Moment (PZM) which is employed inside the local regions of facial area of identical twins images. To evaluate the proposed method, two datasets, Twins Days Festival and Iranian Twin Society, are collected where the datasets includes scaled and rotated facial images of identical twins in different illuminations. The experimental results demonstrates the ability of proposed method to recognize a pair of identical twins in different situations such as rotation, scaling and changing illumination

Automatic data clustering through determination of optimal number of clusters from the data content, is a challenging proposition. Lack of knowledge regarding the underlying data distribution poses constraints in proper determination of the inherent number of clusters. A differential evolution (DE) algorithm based approach for the determination of the optimal number of clusters from the data under consideration, is presented in this article. The optimum number of clusters obtained by the algorithm is further validated by means of a proposed fuzzy intercluster hostility index between the different clusters thus obtained. Applications of the proposed approach on clustering of real life gray level images indicate encouraging results. The proposed method is also compared with the classical DE (which operates with a known number of classes) and the automatic clustering DE (ACDE) algorithms.

Though beaconless geographic routing protocols get rid of the overhead caused by the periodic beacon messages to be broadcast in case of beacon based approaches. But, most of the existing beaconless routing protocols do not consider remaining energy of nodes while making routing decisions. This may result in the repetitive selection of a particular node which is at shortest distance from destination, among its neighbors. This will result in its battery power to drain out faster causing a possible hole in the network. Also most of the existing geographic routing algorithms assume a two-dimensional topology. But, some real world applications demand a Wireless Sensor Network (WSN) to operate in three dimensional space. This paper proposes an energy aware beaconless geographic routing approach for three dimensional WSNs. It takes into account energy budget of nodes besides the distance, in next hop forwarder selection process. This increases the lifetime of the network by maximizing the lifetime of the nodes. The sim ulation results also validate the proposed approach and are being presented in this paper.

Color, texture and shape information have been the primitive image descriptors in content based image retrieval systems. This paper presents a novel framework for combining all the three i.e. color, texture and shape information, and achieve higher retrieval efficiency. The image is partitioned into nonoverlapping tiles of equal size. The color moments and moments on gabor filter responses of these tiles serve as local descriptors of color and texture respectively. This local information is captured for two resolutions and two grid layouts that provide different details of the same image. An integrated matching scheme, based on most similar highest priority (MSHP) principle and the adjacency matrix of a bipartite graph formed using the tiles of query and target image, is provided for matching the images. Shape information is captured in terms of edge images computed using Gradient Vector Flow fields. Invariant moments are then used to record the shape features. The combination of the color, texture and shape features provide a robust feature set for image retrieval. The experimental results demonstrate the efficacy of the method.

Intermittent availability of grid resources results in delays or failures of application execution. Hence, the reliability of application execution declines. In order to achieve a reliable application execution, a consistent availability of computing service is required. This paper proposes a grid computing system that achieves a consistent availability in order to achieve a reliable application execution. In the proposed system, steady state availability is achieved for longer durations. Therefore, the system may be deployed to execute longduration applications. The availability and reliability of the proposed computing service is analyzed using a Markov model. Simulation results prove that the proposed system achieves better reliability and availability compared to the existing replicated application execution system proposed in grid environment.

The user-level brokers in grids consider individual application QoS requirements and minimize their cost without considering demands from other users. This results in contention for resources and sub-optimal schedules. Meta-scheduling in grids aims to address this scheduling problem, which is NP hard due to its combinatorial nature. Thus, many heuristic-based solutions using Genetic Algorithm (GA) have been proposed, apart from traditional algorithms such as Greedy and FCFS.

This paper presents an agent oriented approach for grid computing. As opposed to existing approaches, agent technology promises a more flexible approach, easier installation and management of the agent framework, and better ability to autonomously recover from failures. The semantically rich, ontological description of the grid applications, services and resources opens the possibility for better monitoring and resource management, and a better user interfaces -both for customers and service providers.
