Recent research in mining user access patterns for predicting Web page requests focuses only on consecutive sequential Web page accesses, i.e., pages which are accessed by following the hyperlinks. In this paper, we propose a new method for mining user access patterns that allows the prediction of multiple non-consecutive Web pages, i.e., any pages within the Web site. Our approach consists of two major steps. First, the shortest path algorithm in graph theory is applied to find the distances between Web pages. In order to capture user access behavior on the Web, the distances are derived from user access sequences, as opposed to static structural hyperlinks. We refer to these distances as minimum reaching distance (MRD) information. The association rule mining (ARM) technique is then applied to form a set of predictive rules which are further refined and pruned by using the MRD information. The proposed approach is applied as a collaborative filtering technique to recommend Web pages within a Web site. Experimental results demonstrate that our approach improves performance over the existing Markov model approach in terms of precision and recall, and also has a better potential of reducing the user access time on the Web

We demonstrate electrical properties of an advanced memory structure with high-k dielectric stack of HfAlO/HfSiO/HfXIO and p-type metal gate IrO 2 . Combining advantages of high-k HfAlO, good trapping capability of HfSiO, and high work function of the IrO 2 gate, we were able to attain much better retention with 10-year DeltaV th decay ratio within 18%, higher erasing speed with DeltaV th of 3V within 0.5ms at Vg equiv -12V, and lower operation voltage as well as lower reading voltage, compared to other contending device structures

In order to classify packet, we propose a novel IP classification based the non-collision hash and jumping table trie-tree (NHJTTT) algorithm, which is based on noncollision hash Trie-tree and Lakshman and Stiliadis proposing a 2-dimensional classification algorithm (LS algorithm). The core of algorithm consists of two parts: structure the non-collision hash function, which is constructed mainly based on destination/source port and protocol type field so that the hash function can avoid space explosion problem; introduce jumping table Trie-tree based LS algorithm in order to reduce time complexity. The test results show that the classification rate of NHJTTT algorithm is up to 1 million packets per second and the maximum memory consumed is 9 MB for 10 000 rules.

A variety modeling approaches assume a relatively static manufacturing network structure and focus on optimizing the flow in the DMN (dynamic manufacturing network). These techniques are unable to model structural and behavioral dynamics of a DMN and little is known about how different manufacturing networks evolve and adapt. In this paper, it proposed a new paradigm for modeling and analysis of the DMN based on the self-organization paradigm. The diverse time-varying structures of a DMN emerge with the interaction of the enterprises with various goal directed behavior to fulfill the stochastic global demand. The DMN co-evolves over time and the environment. There is a co-symbiosis relationship among the various enterprises of the DMN. A simulation model based on multiagent approach indicates the emergence, co-evolution and co-symbiosis of the DMN. © Professional engineering Publishing 2004.

Grid services provide an important abstract layer on top of heterogeneous components (hardware and software) that take part into a Grid environment. In this scenario, applications, like scientific visualization, require access to data of non-conventional data types, like fluid path geometry, and the evaluation of special user programs on these data. In order to support such applications we are developing CoDIMS-G, which is a data and program integration service for the Grid. CoDIMS-G provides users transparent access to data and programs distributed on the Grid, as well as dynamic resource allocation and management. We conceived a new node scheduling algorithm and designed an adaptive distributed query engine for the grid environment. Copyright 2004 ACM.

In this paper, we explore the domain of American Football TV broadcasting with respect to interesting event detection. Most of the existing methods achieve the goal of event detection in sports video using some type of shot or scene based approaches. Many problems arise when it comes to work in the shot or scene level in the American Football domain. The big amount of camera movement, such as tilting, zooming, panning, and the large number of different angles used by different broadcasting networks make it very difficult to work in the shot/scene level. We will show how in any of these two levels, over segmentation is almost inevitable. We also propose a novel concept that answers most of the problems of the domain we work on. This is the concept of "unit." A unit is defined as good workable data, which is not necessary to be very accurate. The main purpose of the unit detection process we present is to locate these potentially interesting segments in the video, and separate them from the rest of the redundant data.) © 2004 IEEE.

The emergence of large information systems has pushed software specification into the area of business modelling to adequately capture and consider business requirements. At the same time, there has been a move toward techniques for specifying the behaviours of and the knowledge associated with intelligent agents as these are increasingly found as important components of those information systems. This paper presents four software models useful for specifying the requirements of an agent oriented information system. Adopting a similar notation for each model smooths the transition between models. It will be shown that it is in the relationships between these models there is scope for capturing purposive descriptions that facilitate reuse at various levels. A commentary on the importance of an explicit representation of the purpose for which a software component is intended is provided followed by an example, from the domain of military simulation, that illustrates the model and its application. The aim of this paper is to present a modelling approach that unifies business models, use case models, agent behavioural models and domain models, for the purpose of specifying an agent oriented information system. © Springer-Verlag Berlin Heidelberg 2004.

Tc-99m HMPAO is a typical tracer used in the analysis of cerebral blood flow. Single photon emission computed tomography (SPECT) brain imaging utilizing Tc-99m HMPAO is thus a popular method to assess brain function. An image analysis system for SPECT images that performs a series of image processing procedures including three-dimensional (3-D) image registration, brain extraction, and intensity normalization, is presented here to map all the 3-D brain data to the same space. Afterward, the aligned images undertake a standard statistical analysis, the paired t test, to detect the areas that have significant deviations between the two sets of images. The statistical t map is then represented with a color plot for each brain slice to indicate the activation foci. The registration results are evaluated on the designed phantom images, the acquired clinical images, and by visual inspection. The experimental studies reveal that the subvoxel accuracy is achieved and the consistency is also maintained. Besides, the resulting statistic maps are found very helpful to doctors for lesion evaluation and localization in the clinical diagnosis of schizophrenic patients. © 2004 IEEE.

We report on the experiments about detection of the THz radiation by silicon FETs with nanometer gate lengths. The observed photo-responses measured as a function of the gate voltage are all in agreement with the predictions of the Dyakonov-Shur theory. The plasma wave parameters deduced from the experiments allow us to predict also the possibility of resonant detection in THz range by nanometer size silicon devices.
