The purpose of this paper is to propose a system and process for maximizing store profits to discover the optimal price pattern among various items based on a purchase prediction models. This system, called PRISM, involves the use of data mining techniques to handle a large amount of customer purchase...

Embedding of paths have attracted much attention in the parallel processing. Many-to-many communication is one of the most central issues in various interconnection networks. A graph $G$ is globally two-equal-disjoint path coverable if for any two distinct pairs of vertices $(u, v)$ and $(w, x)$ of $G$,...

People pay much attention to the technology of data mining recently and more and more research institutions begin to buy the databases to analyze. If it doesn’t concern customer’s secrets the enterprises would also like to sell their data warehouse to do the research. Therefore, it becomes an important...

In this paper, we develop a heuristic algorithm to construct an efficient object tracking in wireless sensor networks (WSNs). Such wireless sensor network has to be designed to achieve efficient object tracking for given arbitrary topology of wireless sensor networks. We consider the two-way object moving...

Researchers usually focused on using unstructured documents as input documents of KeyGraph. But the unstructured documents might results in unclear keywords and meaningless keywords. Although traditional document preprocessing could dismiss some of the problems, generating complex and unreadable KeyGraph...

Assume that n is any positive integer. The brother tree BT(n)is an interesting family of 3-regular planar bipartite graphs recently proposed by Kao and Hsu. In any BT(n), we prove that there exist three internally-disjoint spanning paths joining x and y whenever x and y belong to different partite sets....

In this study, a computation-aware scheme for motion estimation (ME) in H.264 is proposed. The objective of the proposed scheme is to properly distribute the available ME computations of the H.264 encoder. Here, the temporal motion vector prediction technique is used to get the predicted motion vector...

In this paper we present a 3-D floorplan representation based on the methodologies of Corner Block List (CBL). Our model is an extension and generalization of the original 2-D CBL and inherits its most crucial advantages including: linear time operations and evaluations, relatively small solution space...

Let G(V, E, W) be a graph n vertices and m edges, where each edge e is associated with a positive distance W(e). The traditional p-Center problem is to locate some kind of facilities at p vertices of G to minimize the maximum distance between any vertex and its nearest facility. This paper proposes a...

In this paper, a scheme that has tamper proofing and recovery abilities is proposed. With the specific DCT frequency coefficients taken as the characteristic values, which are embedded into the least significant bits of the image pixels, it is used to provide proof of image integrity. If the image is...

Image hiding is hiding a secret image embedding to a cover image. This paper intends to propose an image hiding method. First, a secret image is compressed by BST. Meanwhile, dividing the compressed data into different ranks depends on the significance. Then, the cover image is transformed into frequency...

In this thesis, we have proposed an anonymous electronic voting scheme with uncoercibility, and we make use of two especial mechanisms called multiple receipts and dual randomization instead of the previous receipt-freeness to achieve the uncoercibility property. Moreover, we also adopt blind signatures...

Web page prediction is a popular personalized service on the Web and has attracted much research attention. One of the most successful and widely used approaches is collaborative filtering. Traditional collaborative filtering requires explicit user participation for providing his/her interest to the...

Most cryptographic works these days have employed mathematical concepts to design cryptosystems and algorithms. Therefore, mathematical concepts have become critical in the designing of cryptosystems, and are generally used to analyze cryptosystems and protocols, supporting the allegation that the intended...

The future multimedia Internet needs mechanisms to provide QoS (Quality of Service) for users. Service curve (SC) is an effective description of QoS and SCED (service curve based earliest deadline first policy) is an efficient scheduling algorithm to guarantee SCs specified by users. Deadline calculation...

A vector algorithm is an algorithm that applies a bounded number of vector operations to an input vector, regardless of the length of the input. The allowable operations are usually restricted to bit-wise operations available in processors, including shifts and binary addition with carry. This paper...

Robust parameter design has been successfully applied to a variety of engineering problems for enhancing the robustness of the system; however, it cannot deal with multiple dynamic quality systems. Although several other approaches have been presented to resolve this problem, they are unable to efficiently...

Overlay network had received great attention in recent years. Overlay network usually used the peer-to-peer(P2P) networking paradigm for enabling end systems to share their resources. Recent researches had proposed many interesting applications on overlay network such as files sharing and multimedia...

Due to congenital restriction of sensors, it is always a crucial issue on how to utilize limited energy effectively. We first put forward a network topology construction method, based on energy saving, including the way of forming a cluster and selecting middle heads and cluster heads. We then employed...

Due to the high complication of collaboration system, this thesis proposes a conceptual framework for collaboration system as a reference architecture for the collaboration systems. In the mean time, this thesis illustrates the functionalities of a collaboration system, the problems it resolved, and...

The challenge of the business decision support domain is that a large amount of diverse information can be potentially relevant to a decision, and that, frequently, the decisions have to be made in a timely manner. This presents the potential for better decision support, but poses the challenge of building...

As collaboration over the Internet becomes an everyday affair, it is increasingly important to provide high quality of interactivity. Distributed applications can replicate collaborative objects at every site for the purpose of achieving high interactivity. Replication, however, has a fatal weakness...

Information security ≠ information system + security features such as access control and intrusion detection. Security considerations must be an integral part of the entire lifecycle of the information system. This paper presents a framework to systematically classify all security considerations throughout...

Protein-protein interactions (PPI) are very important to the understanding of metabolic pathway. Many digital publications are available today; some of them discuss PPI and some of them do not. If machine learning techniques can be used to detect those PPI documents automatically, it would save researchers...
