Data Mining - Concepts and Techniques.

The objective of this paper is to give a comprehensive introduction to applied cryptography with an engineer or computer scientist in mind. The emphasis is on the knowledge needed to create practical systems which supports integrity, confidentiality, or authenticity. Topics covered includes an introduction to the concepts in cryptography, attacks against cryptographic systems, key use and handling, random bit generation, encryption modes, and message authentication codes. Recommendations on algorithms and further reading is given in the end of the paper. This paper should make the reader able to build, understand and evaluate system descriptions and designs based on the cryptographic components described in the paper.

The hybrid teaching assistant for developing interactivity and comprehension is a model to enhance students' learning by involving them in different testing types and discussions, providing them with advices and allowing them to send their feedbacks. The system makes use of the Internet and Communication Technologies (ICT) to provide a reliable and secure environment. The system consists of exams, discussions, query, charts and feedbacks. Web and mobile phone SMS are used as a communication base among the system's users. The system is hybrid two directional because students can answer the questions using the web form or the SMS form. In addition, students can receive advices and send their comments in both ways. Experiments results showed that students were more enthusiastic during the lesson, they were totally involved in the class room and they achieved better grades. Answers charts improved students' cooperation since they need to discuss the choices to find the correct answer.

Hybrid Teaching Assistant for Developing Students Interactivity and Comprehension

Workflow scheduling is the way to schedule the complex scientific workflow In a cloud platform, the resources can be utilized more effectively and efficiently by scheduling the workflow properly In this paper, an agent-based workflow scheduling mechanism on cloud environment is proposed We implement a set of agents that can federate multiple clouds and automatically monitor the entire system, and manage the job if it's a workflow job We also implement a dynamic job dispatching algorithm to reduce the VM usage amount and improve the resource utilization

Implementing a Workflow Agent on Federated Cloud

With the growth of internet, the requirement for the communication and message exchanges between programs becomes more and more important. The Message-Oriented Middleware (MOM), such as Java Message Service (JMS), could not only greatly reduce the technical learning curve for programmers but also have some amazing characteristics: such as reliable, secured, and event-driven. In the traditional client-server architecture, not only the client side program has to maintain the resource for connections and memory management, but also the server side has to send out several copies of duplicated messages per amount of connected clients. It not only wastes the system resource but also the network bandwidth. A system this paper developed is Fast Java Messaging 2 (FJM2), it's a enhancement version from Fast Java Messaging (FJM). It creates a whole new JMS provider which is distributed, high performance, reliable, and easy to use and deploy. While compared with FJM, FJM2 adapts a more efficient communication protocol - Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM), and does not adapt topic addressing. Moreover, FJM2 has the ability to work across WAN environment to extend the system coverage, and could be adapted for more different application scopes. It would benefit those who want to create a MOM system based on Java and multicast protocol.

FJM2: a decentralized JMS system

The tree quorum algorithm (TQA) uses a tree structure to generate intersecting (tree) quorums for distributed mutual exclusion. This paper analyzes the number of messages required to acquire a quorum in TQA. Let i be the depth of the complete binary tree used in TQA, and let M/sub i/ be the number of messages required to acquire a quorum or to determine that no quorum is accessible. We discuss M/sub i/ as a function of i and p, where p ( 1/2 >

In this paper, we propose an Information Storage and Retrieval Facility based on the CORBA. This facility provides information search, retrieval and storage service. To define these services, we referred the Z39.50 and defined a set of interfaces by CORBA IDL. In addition, other information storage respect services, such as information update, information update notify, and information version control etc., and more other services, such as initial service, close service, and search command forward and distribution etc., were provided in this facility. Based on this facility, programmer can add the capability of query Z39.50 server into applications and also can integrate various data sources and provide an uniform interface. Finally, we also implement an experimental library management system to verify our design.
