Mammogram Image Nucleus Segmentation and Classification using Convolution Neural Network Classifier
Breast Cancer is one of the dangerous diseases which lead in resulting deaths among women. This is due to the presence of cancerous cells that are produced in extra amount of proportion which can replace the neighboring non-cancerous cells or it can infect all over the body. As the breast cancer concerns women mostly at the age of 40, they are asked to attain the regular mammographic screening, since mammography is most reliable method for cancer detection at early stages. Mammogram is the most common method used for breast imaging. It helps in examine the presence of cancer at early stages and help in reducing the mortality rate by 25-30% in screened women. There occur many different types of breast cancer such as: mass, micro calcification clusters, architectural distortion and asymmetry breast tissue. This dissertation carries the masses problem and deals with its shape and texture feature for classification. Various type of techniques and methodologies are present in mammography which helps to find out the presence of cancer and also multiple ways to detect it in its early stage so that the patient affected by it could not lead to death. Mammography is the most common, safe and inexpensive methodology suggested whose standard image database could be used for training the learning machine. In this dissertation nucleus segmentation is used to find out the region of interest (ROI). The result of ROI is further used for extracting the valuable shape and textural features by using geometrical features, GLCM and GLDM for classifying the cancer through the machine learning approach i.e. CNN (Convolution neural networks). CNN remove the overlapping of features obtained after segmentation. Hence, CNN is used to evaluate the performance through defining accuracy, precision, and recall and also compare the results with existing logistic regression and neural network classification technique.

Image Encryption using Huffman Coding for Steganography, Elliptic Curve Cryptography and DWT for Compression
An abstract is a brief summary of a research article or in-depth analysis of a particular subject or discipline, and is often used to help the reader quickly ascertain the paper's purpose. Images can be encrypted in several ways, by using different techniques and different encryption methods. In this paper, I am using Huffman Coding method for image steganography, Elliptic Curve Cryptography for image encryption and Discrete Wavelet Transform for image compression. In my work I am using steganography, encryption and compression all together on the image data. After applying all these techniques on image data it results in an encryption method which is highly secure. For the implementation of the proposed work we are using Matlab software.

A Study on Friction Stir Welding of Various Aluminum Alloys
The comprehensive body of knowledge that has built up with respect to the friction stir welding (FSW) of aluminum alloys since the technique was invented in 1991 is reviewed on this paper. The basic principles of FSW are described, including metal flow and thermal history, before discussing how process parameters affect the weld microstructure and the likelihood of defects. Finally, the range of mechanical properties that can be achieved is discussed. It is demonstrated that FSW of aluminum is becoming an increasingly mature technology with numerous commercial applications. Keywords - Friction stir welding, metal flow, process parameters, mechanical properties

Call Admission Control (CAC) with Load Balancing Approach for the WLAN Networks
-- The cell migrations take place between the different network operators, and require the significant information exchange between the operators to handle the migratory users. The new user registration requires the pre-shared information from the user’s equipment, which signifies the user recognition before registering the new user over the network. In this thesis, the proposed model has been aimed at the development of the new call admission control mechanism with the sub-channel assignment. The very basic utilization of the proposed model is to increase the number of the users over the given cell units, which is realized by using the sub-channel assignment to the users of the network. The proposed model is aimed at solving the issue by assigning the dual sub channels over the single communication channel. Also the proposed model is aimed at handling the minimum resource users by incorporating the load balancing approach over the given network segment. The load balancing approach shares the load of the overloaded cell with the cell with lowest resource utilization. The proposed model performance has been evaluated in the various scenarios and over all of the BTS nodes. The proposed model results have been obtained in the form of the resource utilization, network load, transmission delay, consumed bandwidth and data loss. The proposed model has shown the efficiency obtained by using the proposed call admission control (CAC) along with the new load balancing mechanism. The proposed model has shown the robustness of the proposed model in handling the cell overloading factors.

Comparative Analysis of PCF, DCF and EDCF over IEEE 802.11 WLANs
with the enhancement of wireless network, QoS has become major researcher area. IEEE802.11 standard has two sub layers MAC protocols like as Distribution Coordination Function (DCF), Point Coordination Function (PCF). Medium access coordination function basically implements the Distribution Coordination Function (DCF) and Point Coordination Function (PCF) which support just to best effort service but have limited to QoS services. A new standard, Enhanced Distribution Coordination Function (EDCF) is reported .The IEEE 802.11e (EDCF) which defines the MAC procedures to support QoS requirements and that specifies distribution based access scheme to access the shared wireless media. In this paper, Protocols are tested under realistic conditions to perform evaluation of the coordination functions. Various parameters such as load, network load, media access delay, data dropped are tested in wireless network. Furthermore, the simulative observation is reported at data rate of 66Mbps using a physical layer protocols such as IEEE 802.11n to stumble the best one to implement with EDCF to achieved improved QoS.

Review on Rank Base Data Routing Scheme with Grey Hole Detection & Prevention in MANETS
MANET (Mobile Ad Hoc Network) is a type of ad hoc network that can change locations and configure itself, because of moving of nodes. As MANETs are mobile in nature, they use wireless connections to connect various networks without infrastructure or any centralized administration. While the nodes communicate with each other, they assist by forwarding data packets to other nodes in the network. Thus the nodes discover a path to the destination node using routing protocols. Gray hole attack among the different types of attacks possible in a MANET. Gray Hole attack is one type of active attack which tends to drop the packets during transmission the routing from source to destination .In this paper, we simulate gray hole attack Detection and prevention technique using AODV and AODV+PSO. Performance metrics Packet dropped or packet loss, End to End delay and Average throughput, the performance analysis has been done by using simulation tool ns-2 which is the main infrastructure.
