In this paper, we adopt SVM classifier combined with PHOG (Pyramid of Histograms of Orientation Gradients) descriptors to implement product-image classification. The support vector machine maps the input vectors into a high-dimension space, in which a max margin supper hyper plane is set up to classify the samples and PHOG can flexibly represent the spatial layout of local image shape. Experimental results showed the effectiveness of the proposed algorithm.

Where, the SDN is an emerging topic that tracts attention due to its paradigm, that splits the control plane form data forwarding plane. According to [2], SDN defines OpenFlow [3] as "key enabler for software-defined networks". However, there have been some debates regarding the scalability of the OpenFlow's controller; this is due to the design of OpenFlow as it depends on a centralized controller to control flows. Manny efforts have been put to solve this issue, one of them is the hybrid control model proposed in [1]; where the original centralized model is preserved, while adding a distributed control model for some specific cases, in order to increase the network's efficiency. And based on the well-established fact, that all computer systems and networks should be secure; in this work, we propose a security method for such distributed control model of SDNs. In which, we aim to secure the flow installation using the distributed control, in addition to enabling safe usage of the distributed control without any chance of malicious use of the distributed control.

This approach uses the Analytic Hierarchy Process (AHP) method in a Peer-to-Peer Service Overlay Network (P2P SON) composed of several service providers in order to select the most suitable one to deliver the requested service. The AHP method takes into account several performance indicators to accomplish the task. The performed evaluation compares simulation results regarding the service providers' selection by using and not using the AHP method. The results show that the use of AHP as a method to select the best service providers is effective, thus resulting in better distributed selections.

Unlike traditional mobile and ad-hoc networks, WSNs depend on battery, dense deployment of nodes in a given physical space and co-ordination to carry out their tasks. In the past few years, there has been lot of research work took place in the area of routing in WSNs and it is proved that the cluster based routing is the one of the best approach to improve the lifetime of the network. The proposed THC protocol makes some assumptions for efficient data routing and network lifetime longevity. The THC protocol transmits its aggregated data to the collecting base station using multipath communication compared to direct communication in LEACH. The results show that THC protocol performs very well and increases the network lifetime.

Until recently, the centralized architecture has been the most popular architecture for providing VoD service to subscribers of cable television network. With the growth of the network, however, this type of architecture has become inapplicable because of the need for a large number of outgoing video streams from the central VoD server, i.e. high bit rate through the central transmission network. The objective of this paper is to compare the necessary bit rates on different network sections of P2P and centralized VoD architecture and to study the influence of the more important parameters on these bit rates.

Emerging Web 2.0 technologies contribute significantly to the fulfillment of key organizational goals and objectives in the public sector. Web 2.0 assist organizations improve employee's productivity, increase communications, information sharing, and improve business processes. The pervasive use of Web 2.0 has created a critical need for effective IT governance procedures. Therefore, investigating Web 2.0 adoption decisions in public organizations is important. Adoption of Web 2.0 entails specifying a framework for Web 2.0 adoption decision accountability, identifying implementation factors and portraying the governance framework of Web 2.0 adoption in the lights of organizational policies, procedures, guidelines and existing organizational IT governance framework.

Algorithms are judged by the running time and space complexity which they take to solve any specific problem. In this papers an efficient sorting algorithm has been introduced, this algorithm is based on dynamic programming technique which is used to solve the optimization problems and here to sort arrays with optimal merges. Algorithm uses a bottom-up approach to compute the pre-sorted sub-sequences of random lengths in a given array of numbers and then sorts the whole array after efficiently combining the identified subsequences by using dynamic programming technique. Overlapping sub-problems are identified while sorting the given array and dynamic programming keeps the track of all the overlapping sub-problems by memorizing the data in a tabular form which is the main theme of the mentioned technique. Running time of the algorithm is compared with the standard merge sort and the results are satisfying.

The most accepted payment mode is credit card for both online as well as regular purchase, pay bills etc. So frauds associated with it are also rising. In real life, fraudulent transactions are scattered with genuine transactions and simple pattern matching techniques are not often sufficient to detect those frauds accurately. Implementation of efficient fraud detection systems has thus become imperative for all credit card issuing banks to minimize their losses. Many modern mechanisms are developed such as CHIP & PIN the mechanism do not prevent the most common fraud type such as fraudulent credit card usages over virtual POS terminals through internet or mail orders. Finally fraud detection is the essential for stop such type of frauds. In this study, classification model based on Artificial Neural Networks (ANN) and Logistic Regression (LR) are developed and applied on credit card fraud detection problem.

Digital Watermarking is a technology used for the copyright protection of digital applications. In this paper, a comprehensive approach for watermarking digital video is introduced. We propose a hybrid digital video watermarking scheme based on Discrete Cosine Transform (DCT) The video frames are first decomposed using DCT and the binary watermark is embedded In this paper, we describe a visible watermarking scheme that is applied into the host video in the DCT domain. A mathematical model has been developed for that purpose. We have also proposed a modification of the algorithm to make the watermark more robust.

The main idea is to use a projector to transfer energy and to provide global positioning information to the robots that are equipped with photodiodes on their top. We project a white image showed a scavenged power of 100 to 200 watts normally tungsten bulbs commercially available in market. Based on the global positioning system, the projector sends regularly a sequence 17 images and the robots decodes them using two photodiodes in order to calculate its own position and orientation inside a defined arena.
