Pervasive networking environment as social infrastructure has been going to become a reality, especially through the recent considerable progress of semiconductor technology. Considering the case where next generation of pervasive networking is realized over ad hoc network suitable for emergency and some tentative event, some ofauthors study about an data- driven imprementation of Ad hoc and ubiquitous communication environment. It is very important to implement effective protocol handling and routing process in Ad hoc networking environment especially. This paper describes the effectiveness ofan implementation ofprotocol off-loader using networking-oriented data-driven processors CUE (Coordinating User's requirements and engineering constraints). In Ad hoc network, it is necessary to realize connection-less protocol such as UDP/IPfor flexible routing and realtime communication. Firstly, this paper discusses data- driven implementation ofprotocol off-loader on CUE networking board to minimize overheads in protocol handling. Then this paper describes architecture of CUE-v2/CUE-v3 which is available version in CUE processors. This paper finally discusses effectiveness ofprotocol handling off-loader using CUE processor system. It shows that data-driven protocol off-loader can keep minimum turn-around time without runtime overheads.

In this paper, we propose the basic framework of point- wise topological logic on completely distributive lattices and explore approximate reasoning in it. The logic of this paper is based on pointwise characterization, therefore the pointwise conception is pervasive. We explore approximate reasoning in abstract logical framework Fl on completely distributive lattice L. We propose the structure of point- wise topological logic F TL , the structure of matching function sigma. and the structure of matching neighborhood group. We investigate approximate reasoning in pointwise topological logic F TL with matching function sigma, develop pointwise topological algorithm of simple approximate reasoning, introduce the essential characteristics of this scheme.

Nitric oxide (NO) detection is a critical issue for environmental safety and medical diagnosis due reasons with regard to the toxic properties for human body and metabolic index for respiratory disease, respectively. Development of gas sensor with high sensitivity is very important because the concentration of NO gas in the environment and respiratory tract is extremely low, therefore not readily detectable. The material with nanostructure can improve the sensitivity of sensor owning to surface effect and size effect. Herein, we developed a new type of gaseous nanosensor assembled by 34 nanowires of conducting polymer, PEDOT: PSS. The nanowires were fabricated by dip pen nanolithography (DPN) with the length of 55 um and diameter of 300 nm between golden wires. The NO gas measurement is based on chemiresistor based methods. The result of dynamic measurement of NO gas at 100 ppm shows repeatability and stability; the recovery time is 10.4 minutes. Moreover, the lowest concentration of NO gas in static measurement is 10ppm at 80 C, which also shows the ability sensing at low temperature.

As the Web increase drastically, more and more entity information come to appear on Web, including their profile information, their web log containing their idea, activity, speech and so on. However, there are many entities sharing same names. Such entities include persons, locations and so on. This paper presents an approach to estimate the number of entities sharing same name by employing many-to-one features. The basic idea is that the entities are not likely to share all other features even if they have the same name. We list some strategies for selecting key features, present an approach to extract the features on Web, and combine them to estimate the entity number. What is more, we also give a method to identify the fake information which will confuse us and filter them.

Hybrid splitting criteria based on purity measures

WSEAS Transactions on computers 2007年第5期6卷 843-850页

Decision trees are one of the most transparent methods probably most often used for solving classification, tasks. In the process of decision tree induction a lot of input parameters have to be fine-tuned in order to obtain good results. However the most important and probably most influential parameter in top-down induction method is a splitting criterion, which can vary from one classification task to another. In this paper we empirically tested four of them, based on well known purity measures, on 54 UCI databases. Although none of the proposed splitting criterion in the literature has proved to be universally better than the rest, they are not always suitable for solving any classification task. Therefore we propose two new splitting criteria: hybrid linear combination of purity measures and voting of purity measures, which obtain at least comparable results to other well-known criteria used in greedy decision tree induction method, while their structure makes them ideal for non-expert users. Boosting was also applied as one of the most successful ensemble methods, which once again proved the ability to significantly improve the classification accuracy on many databases.

Reliable and Energy Efficient Protocol for Wireless Sensor Network

Tsinghua science and Technology 2007年第S1期12卷 95-100页

作者：阚保强蔡理徐勇军 College of Science Air Force Engineering University Key Laboratory of Computer System and Architecture Institute of Computing TechnologyChinese Academy of Sciences

Low-power design is one of the most important issues in wireless sensor networks (WSNs) , while reliable information transmitting should be ensured as well. Transmitting power (TP) control is a simple method to make the power consumption down, but excessive interferences from potential adjacent operating links and communication reliability between nodes should be considered. In this paper, a reliable and energy efficient protocol is presented, which adopts adaptive rate control based on an optimal TP. A mathematical model considering average interference and network connectivity was used to predict the optimal TP. Then for the optimal TP, active nodes adaptively chose the data rate with the change of bit-error–rate(BER) performance. The efficiency of the new strategy was validated by mathematical analysis and simulations. Compared with 802.11 DCF which uses maximum unified TP and BASIC protocol, it is shown that the higher average throughput can achieve while the energy consumption per useful bit can be reduced according to the results.

The need to examine and manipulate large surface models is commonly found in many science, engineering, and medical applications. On a desktop monitor, however, seeing the whole model in detail is not possible. In this paper, we present a new, interactive Focus+Context method for visualizing large surface models. Our method, based on an energy optimization model, allows the user to magnify an area of interest to see it in detail while deforming the rest of the area without perceivable distortion. The rest of the surface area is essentially shrunk to use as little of the screen space as possible in order to keep the entire model displayed on screen. We demonstrate the efficacy and robustness of our method with a variety of models.

In this paper, we presented a method to improve structural modeling based on conserved domain clusters and structure-anchored alignments. We first constructed a template library of structural clusters for all conserved sequence domains. Then, for each cluster, we built the profile using the structure and sequence information. Finally we use the profile and structural alignments as anchors to increase the alignment accuracy between a query and its templates. Our preliminary results show that this method can be used for the partial prediction for a majority of known protein sequences with better qualities. Copyright 2007 ACM.

Self-adjusting predicted particle swarm optimization

引用

Journal of Information and Computational science 2007年第2期4卷 483-496页

作者： Cui, Zhihua Zeng, Jianchao Sun, Guoji State Key Laboratory for Manufacturing Systems Engineering Xi'an Jiaotong University Xi'an 710049 China Division of System Simulation and Computer Application Taiyuan University of Science and Technology Taiyuan 030024 China

Predicted particle swarm optimization is an enhanced version aiming to increase the utilization ratio of velocity information, and the performance heavily relies upon the parameters settings. According to control theory, the trajectories of position and velocity vectors of each particle can be both viewed as oscillatory links, and the relationship between inertia weight and accelerator coefficients is obtained. Thus, a self-adjusting parameter strategy is proposed. Simulation results show the new proposed strategy is powerful and useful.
