Abstract: To hide the communication of users, the anonymity systems pack the application data into equal – sized cells. The size of IP packets in the Tor network can be very dynamic and the IP layer may be repack cells. A new cell-counting attack against Tor allows the attacker to confirm anonymous communication relationship among users very quickly. By varying the number of cells in the target traffic at the malicious exit onion router, the attacker can embed a secrete signal into variation of cell counter of the target traffic and it will be carried and arrive at the malicious entry onion router.

Abstract: This paper proposes a Real-Time Link Reliability Routing protocol for wireless sensor networks (WSNs). The protocol achieves to reduce packet deadline miss ratio while considering link reliability, two-hop velocity and power efficiency and utilizes memory and computational effective methods for estimating the link metrics. Numerical results provide insights that the protocol has a lower packet deadline miss ratio and improved sensor network lifetime. The results show that the proposed protocol is a feasible solution to the QoS routing problem in wireless sensor networks that support real-time applications..

Abstract: Personal identification based on Biometrics technology is a trend in future. Iris Recognition is regarded as a high accuracy verification technology when compared to traditional approaches. In real-time Iris Recognition, Iris Localization is very important step for Iris Recognition. So, the Iris Masks plays an important role in iris recognition. This Iris Mask indicates which part is occluded or contaminated by noisy image artifacts such as eyelashes, eyelids, eyeglasses frames, and specular reflections. If the Iris Mask is inaccurate, it will decrease its performance in Iris Recognition system. So, we use learning- based algorithms to estimate accurate Iris Masks from Iris Images, which propose to use Figueiredo and Jain's Gaussian Mixture Models (FJ-GMMs) to model the underlying probabilistic distributions of both valid and invalid regions on iris images. We also explored possible features and found that Gabor Filter Bank (GFB) provides the most discriminative information for our goal. Finally, we applied Simulated Annealing (SA) technique to optimize the parameters of GFB in order to achieve the best recognition rate.

Index Terms: Gaussian mixture models, iris mask, iris recognition, iris occlusion estimation, simulated annealing.

Abstract: To facilitate the access to computer systems, computer scientists choose to design interactive mechanisms which are more adapted than traditionally used devices such as keyboard or mouse. The use of gestures modalities has been extensively studied in recent years by the human machine interaction community. Augmented Reality is one of the mechanisms of interaction that allow implementing the human-machine communication. Indeed, its principle is to mix the real world and the virtual world.

Title	:	Routing Framework for Delay Tolerant Networks using BayesiaLab
Country	:	India

Abstract:Routing in delay tolerant networks (DTN) can benefit from the fact that most real life DTN, especially in the context of people-centric networks (e.g. Pocket Switching Networks (PSN)), exhibit some sort of periodicity in their mobility patterns. For example, public transportation networks follow periodic schedules. Even most individuals have fairly repetitive movement patterns, for example, driving to and from work at approximately the same time everyday. This paper proposes a BayesiaLab tool based DTN routing framework that adopts a methodical approach for computing the routing metrics by utilizing the network parameters (e.g. spatial and temporal information at the time of packet forwarding) that capture the periodic behavior of DTN nodes.

Abstract: Cloud computing has a great tendancy of providing robust computational power to the society at reduced cost. The wide adoption of this promising computation model is prevented by security which is the primary obstacle especially for customers when their confidential data are consumed and produced during the computation. The data stored in the cloud may be frequently updated by the users. It has been reported by many authors on auditing methods to efficiently audit the cloud data storage without challenging the local copy of data, and introduce no additional on-line load to the cloud user.

Abstract: Tracking object in videos has applications in video surveillance and other main applications. The absence of a commonly adopted performance evaluation Framework is hampering advances in the design of effective video trackers. Tracking an object in a video is a challenging process. The proposed algorithm to track the multiple objects in a video even in conditions such as diversity of targets (head, vehicle and person) and challenges (occlusions, background clutter, pose changes and scale changes).The objects can be tracked based on the compression domain and pixel domain. Using background subtraction method the objects in the fore ground are extracted. The objects in the frame are then detected and then the detected objects are labelled. Performance analysis is done and the tracking accuracy and tracking failures are measured. The proposed system is used to improve the tracking accuracy and decrease the tracking failures in the video tracking process. Finally Performance analysis shows that for different type of trackers our algorithm shows best performance.

Abstract: Data aggregation is implemented in wireless sensor networks to reduce data redundancy and to summarize relevant and necessary information without requiring all pieces of the data and to reduce large amount of data transmission. Homomorphic public encryption is the proposed scheme designed for multi-application environment. The base station extracts application-specific data from aggregated cipher texts, and compromised attacks in single application environments, and to degrade damage from unauthorized aggregations. To enhancing a new approach as symmetric key algorithm used where the keys for encryption and decryption are done in same shared secret. These keys are used to provide security in data aggregation and separate the cipher text when it stored and retrieve from database. In Database As a Service (DAS) model, the client has to secure their database. The attacker cannot change the data because it is dynamically created.

Abstract: GIS can manage remotely sensed images, users must have an appropriate digital map that represents lands each one has information according to its owner, status, and some other data. The classification of such lands is a great problem which take long time depending on human efforts. Many kinds of classifications had been used , one of them is the use of supervised multi-layer perceptron with backpropagation neural network classifier and using second order statistics Gray Level Co-occurrence Matrix (GLCM) to calculate eight textural features for each one of three visible bands (RGB) for each land sample. In this research we analyzed the GLCM feature extraction algorithm to detect the appropriate angle that can be chosen ,

Title	:	Cosine Similarity Based Clustering For Software Testing Using Prioritization
Country	:	India
Authors	:	R.Kanimozhi, Prof.J.RBalakrishnan
	:	10.9790/0661-16177580

Abstract: prioritizing the test cases helps to increase the rate of fault detection. The difficulty of ensuring the dependability in the growth of the scale of software and software testing in distributed environment a sufficient software testing technique is not possible. It is often difficult to test a parallel and distributed system in the real world deployment. Hence in this paper, after generating test cases using functional requirements, dependency structure prioritization technique is used to prioritize the test cases based on the functional structure of dependency. A new technique namely cosine similarity based clustering approach is used to group the test cases based on the similarity values to form clusters. Each cluster is distributed in the distributed environment for parallel execution in order to reduce the computation time and to improve the rate of fault detection.

Abstract: This study detailed the effect of simultaneous multiple intrinsic and extrinsic factors on the characteristics of Sfax activated sludge wastewater treatment plant (WWTP), located in Southern East Tunisia. The plant performance was evaluated through descriptive and statistical analysis of quantity and quality data of both raw wastewaters and treated effluent over a period of three years (2008 – 2010). Despite the rehabilitation, poor performance was shown to be attributed to raw wastewaters quality, civilization populations, bad functioning of the aerators and the industrial fallouts and deposits.

Abstract: Semantic Web Service is an emerging technology which is growing popularly, due to the increased level of machine understandability. In this paper we propose semantic web service discovery framework using Sense based match making mechanism that provides flexibility for searching exact word. Our work is mainly focused on to overcome the disambiguation problem and also for making the use of semantic web easier. It incorporates NLP techniques for disambiguating words, meanings and establishing a context for a set of words. This mechanism improves the quality of discovery process which enhances the user selection and also helps to express the desired semantic Web services. The experimental test shows the positive impact on the discovery process.

Keywords: Semantic Web Service, Ontology, Match Making, Natural Language Processing.
