摘要：
Crankshaft manufacturing is an important step of engine manufacturing processes. By using computer technology, the multi-parameter co-measuring system is able to. improve the automaton in the measuring process. and to measure multi-dimension. shapes and position by once positioning thus it will be surely wide applied in the crankshaft production. This paper will introduce two types of multi-parameter co-measuring systern and their application in the production. The first is crankshaft bent deformation measuring machine systern. This system is able to Measure radial flounce quantum of each main shaft neck and bent deformation. In order to describe the crankshaft bent deformation status and accurately to measure its deformation. we introduce the conception of deformation vector. Based on the deformation vector. the calibration vector is defined for the purpose of calibration by spinning. The second is the crankshaft pneumatic-electric measuring system. Based on spray type pneumatic probe receiving the dimension variation of the measured crankshaft. the movement variation be converted into pneumatic pressure variation and converted into modular voltage signal by pneumatic-electric converter. Being amplified, it becomes the digital signal by multi-route data picking card and finally complete the operations of display. save, print, alarm and statistic analysis. The pneumatic-electric measuring system is a kind of measuring system, which uses the pneumatic probe as the measurement. converts the pressure into electric signal and treats it afterwards. It makes up the shortage of the pneumatic measurement and electric induction measurement. It has the advantage of simplified mechanical measuring system, convenient data treatment and therefore it is an economic and practically used measuring method.

摘要：
In this paper we present an approach to mining domain-dependent ontologies using term extraction and relationship discovery technology. There are two main innovations in our approach. One is extracting terms using log-likelihood ratio, which is based on the contrastive probability of term occurrence in domain corpus and background corpus. The other is fusing together information from multiple knowledge sources as, evidences for discovering particular semantic relationships among terms. In the experiment, we also improve the traditional k-mediods algorithm for multi-level clustering. We have applied our approach to produce an ontology for the domain of computer science and obtained promising results. http://www.aclweb.org/anthology/Y06-1020

摘要：
On reviewing the local-world evolving network model, this paper proposes a self-organization Internet topology model based on message transfer in terms of the statistical characteristic and forming mechanism of Internet. This topology model simulates the growth of the whole Internet dynamically: some isolated nodes which are randomly distributed on a plain building connections by sending messages to each other; each node decides how to build connection according to the message it received, in order to form a self-organized hierarchical Internet topology from bottom to top. Simulation results show that the topology produced by this model can accurately reflect the realistic Internet topology on degree distribution, clustering coefficient and so on.

摘要：
When the capacity of a network is expanded, the investment cost should be taken into consideration. We hope to obtain the largest capacity expansion with minimum investment cost. This paper utilizes the labeling algorithm of maximum flow to find out bottleneck arcs and discusses Network Capacity Expansion with Minimum Cost (NCEMC) in two aspects. Then a mathematical model for the NCEMC problem is given and the corresponding capacity expansion algorithm and theoretical analysis are presented.

摘要：
Multipath routing allows two network nodes to exchange messages over multiple paths. However, due to the wireless multicast advantage (WMA), there exists serious collision among multiple paths. Thus, data transfer rate of most multipath routing, even if it is node-disjoint, is not so high as its anticipation. This paper proposes a Node-Disjoint multipath routing based on Correlation Factor (NDCF) algorithm for ad hoc networks. To avoid collision maximally, this algorithm defines correlation factor to weigh the collision probability among node-disjoint multipaths when transmitting data simultaneously, then finds the node-disjoint multipath, whose collision probability is minimum. Our preliminary simulation results show that NDCF algorithm can significantly reduce end-to-end delay and improve packet delivery ratio.

摘要：
Topology control has been well studied as a hotspot in wireless ad hoc networks. However, due to the strictly limited resources, few topology control methods take into account lowering interference of the entire network as the main goal. This paper proposes an interference-minimized control topology algorithm (IMBP) based on path-interference measure for ad hoc networks. Derived from the concept of measure, the IMBP presents a new metric that quantifies the degree of interference of the entire network, and gives an algorithm of computing node interference measure (CNIM), then obtains the interference-minimized network topology while preserving the connectivity of ad hoc networks. Our extensive simulation results show that IMBP algorithm can significantly reduce interference and improve the connectivity of ad hoc networks
摘要：
In advance reservation environment, failure strategy is very important to keep the normal discover running of whole system. One job's overtime (exceeding its booked time) may lead to a serious of jobs' abnormal termination in co-allocation environment. So there should be some strategies to solve this problem. In this paper, a novel overtime-tolerance strategy is introduced The strategy can tolerate active job exceeding its booking time and redirect transparently later inactive jobs to other resources. The architecture of implementing our strategy is described in this paper too. Simulation shows our overtime-tolerance strategy can decrease the abnormal termination ratio and improve the system throughput.
摘要：
Many routing protocols have been proposed for sensor network, but most of them have not designed with security as a goal. Sensor protocol for information via negotiation (SPIN) protocol is a basic data centric routing protocol of sensor networks. In this paper, we present the design of secure-SPIN, a secure extension for the SPIN protocol. We divide secure-SPIN into three phases and use some cryptographic functions that require small memory and processing power to create an efficient, practical protocol. Then we give security analyses of this protocol. It shows that this secure protocol may increase the data communication security in wireless sensor networks.

摘要：
In this paper a wavelet-based HVS characteristic watermarking algorithm for copyright protection of digital image is presented. Instead of using a random sequence, a visually meaningful gray scale logo is used as watermark. Our techniques apply the Arnold transform to disturb watermark and split the wavelet coefficients of the low frequency into small blocks. Watermark is embedded into the maximal absolute value of these coefficients selected based on the weight factors calculated by exploiting the human visual system (HVS) characteristics. The experiment results demonstrated the new algorithm is robust for scaling, rotation attack, JPEG compression and noise attack.

摘要：
In this paper we propose a conceptual framework for relational database based on secret sharing technology. We offer a technique to break the main secret into multiple parts and hide them individually in a relational database. The Lagrange Interpolating Polynomial method is used to recover the shared secret. The (k, n) threshold scheme is used to decide the minimum number of parts required to recover the secret data completely. Through deep data analysis, experimental results show how the proposed scheme can offer robust mechanism to protect data loss especially for the tuples deleting.
