Abstract: Fingerprint-based methods are widely adopted for indoor localization purpose because of their cost-effectiveness compared to other infrastructure-based positioning systems. However, the popular location fingerprint, Received Signal Strength (RSS), is observed to differ significantly across different devices' hardware even under the same wireless conditions. We derive analytically a robust location fingerprint definition, the Signal Strength Difference (SSD), and verify its performance experimentally using a number of different mobile devices with heterogeneous hardware. Our experiments have also considered both Wi-Fi and Bluetooth devices, as well as both Access-Point (AP)-based localization and Mobile-Node (MN)-assisted localization. Also compare these SSD-based localization algorithms' performance against that of two other approaches in the literature that are designed to mitigate the effects of mobile node hardware variations, and show that SSD-based algorithms have better accuracy. To justify this we make a data transfer between the nodes using the SSD-based and it proves the accuracy.

Abstract:The Classification for Pap smear Diagnosis aims at classifying the Pap smear cells whether it is affected or not. The term "Pap-Smear" refers to samples of human cells stained by the so-called Papanicolaou method. The Papanicolaou method is a medical procedure to detect pre-cancerous cells in the uterine cervix. The median filter is used to remove the noises in the cell, and then the features are extracted using gray level co-occurrence matrix technique. k-NN classifier, Baye's classifier and ANN classifiers are used for the classification problem.. The classified cells are normal and abnormal.
Keywords:- Bayesian classifier, Genetic Algorithms, Nearest Neighbor based Classifiers, Neural Network, Pap-Smear Classification.

Title : Intelligent boundary alert system using GPS
Country : India
Authors : C. Sheeba thangapushpam

Abstract: The Tamil Nadu factor in India-Sri Lanka relations that had been quiet for long has come to the fore in the form of the fishermen issue. Frequent incidents of fishermen from Tamil Nadu getting shot in the Sri Lankan's maritime boundary have enraged all citizen of the state. From Tamil Nadu about 18,000 boats of different kinds conduct fishing along the India - Sri Lanka maritime border. Ever since violence broke out in Sri Lanka two decades ago, fishing activity has not been peaceful. Tamil Nadu fishermen are arrested, or shot, by the Sri Lankan Navy. In this problem will be solved by using An Intelligent Boundary Alert System (IBAS).An IBAS system induces the new methodology for saving the fishermen valuable life and their properties from the Sri Lankan's navy. The main objective of this system is used to help the fishermen to navigate inside our maritime country border.

Abstract: Recognition and classification of human actions for the purpose of safety from video sequences is always a challenging problem because of the variations in its environment, different backgrounds used in videos, appearance of actors and their clothing, so in our work we propose a method for constructing effective and appropriate codebooks for action categorization. In the formation of codebook fuzzy C-means clustering algorithm and Pairwise Nearest Neighbor algorithm (PNN), is used and hence the performance of these methods are compared and analyzed on Weizmann dataset.

Country : India
Authors : R.Aishwariya, M.Kalaiselvi Geetha, M.Archana

Abstract: The usage of medical images has been increasing tremendously due to a collection of thousands of medical images every day in medical institutions. Due to the increase in medical images there is a rising need of managing the data properly and accessing it accurately. Finding the correct boundary in noisy images is still a difficult task. It introduces a new edge following technique for boundary detection in noisy images. Use of the proposed technique demonstrates its application to diverse cases of medical images. The proposed technique can detect the boundaries of objects in noisy images using the information the fracture detection on the x-ray images is founded. The proposed technique for the canny edge detector in the x-ray image locates the edges and using the boundary detection, the system which detect the fracture automatically. The boundary detection techniques also implemented in the models are Active Contour Model, Geodesic Active Contour Model and compare the accuracy of detecting is analyzed and tested by using Mat lab 2013 version.

Title : EMOSPARK-A Revolution in Human Emotion Through Artificial Intelligence
Country : India
Authors : Deepika.S, MadhuMidha.S, BanuMathi.I, PriyaDharsini.G

Abstract: For as long as we've been imagining emotionally intelligent machines, we have pictured something at least mildly resembling human form. From George Lucas' C-3PO, to the recently-developed Robokind Zeno R25, our vision for robotic companionship has typically involved two arms and two legs. Taking a different approach is inventor of the Emo Spark console Patrick Levy Rosenthal, who aims to bring artificial intelligence to consumers in the form of a cube small enough to fit in the palm of your hand. Emo Spark is an Android powered Wi-Fi/Bluetooth cube that allows users to create and interact with an emotionally concise intelligence through conversation, music, and visual media. Emo Spark will take not only gaming, but also your TV, smart phone or computer to an entirely different level from anything ever experienced before. media. Over time, the cube creates a customized Emotional Profile Graph (EPG) which collects and measures a unique emotional input from the user. The EPG allows the cube to virtually "feel" senses such as pleasure and pain; and "expresses" those desires according to the user. The future of AI interactions is here. Emo Spark is a brand new innovation from Emo Shape, Ltd. that allows you to transfer your real life emotions and desires directly onto a digital platform using state of the art AI measurements and technology. The digital world will never be the same again. This is the world's first "Emotional Intelligence" device and its capabilities and benefits are unlimited. The Emo Spark uses emotion text and content analysis to measure the emotional responses of several people all at the same time.

Title : AFS: Privacy-Preserving Public Auditing With Data Freshness in the Cloud
Country : India
Authors : P. Maheswari, B. Sindhumathi

Abstract: In Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services. The integrity of cloud data is subject to skepticism due to the existence of hardware/software failures and human errors. Several mechanisms have been designed to allow both data owners and public verifiers to efficiently audit cloud data integrity without retrieving the entire data from the cloud server. However, public auditing on the integrity of shared data with these existing mechanisms will supports public auditing on shared data stored in the cloud that exploit ring signature to compute verification metadata needed to audit the correctness of shared that a third party auditor (TPA) is able to verify the integrity of shared data for users without retrieving the entire data. Meanwhile, the identity of the signer on each block inshared data is kept private from the TPAalso able to perform multiple auditing tasks simultaneously instead of verifying them one byone.In this paper, we proved the data freshness(proved the cloud possesses the latest version of shared data)while still preserving identity privacy.Our experimental result ensures that retrieved data always reflects the most recent updates and prevents rollback attacks.
