＜正＞ At present, the most common micro/nano-scale fabrication processes include the plane silicon process based on IC technology, stereo silicon process, LIGA, quasi-LIGA based on near ultra violet deep lithography, MEMS, energy beam etching and micro/nano-machining, etc. A common problem for these processes is the difficulty to fabricate arbitrary form for 3.dimensional micro/nano-parts, devices or mechanisms. To develop advanced MEMS manufacturing technology, and to achieve fabrication of true 3.dimensional parts, devices or mechanisms, this paper proposes a nanofabrication technology for rapid prototyping of 3.dimensional parts, using plasma chemical vapor deposition （PCVD）. This process can be describes as follows;A laser beam is produced by a low power, quasi molecule laser. It enters the vacuum chamber through a window, and is focused on with the substrate surface. A gas in the chamber is ionized by the laser beam to produce PCVD on the substrate surface, and forms a particle of the size of Φ100 nm （its thickness is about 100 nm）. When the laser beam moves along X-axis, many particles form a line. Then the laser beam moves one step in Y-axis to form a new line. A plane is completed by many lines. Then the substrate moves in Z-axis to form new plane. Eventually, many planes form a 3.dimensional component. Using available CAD/CAM software with this process, rapid prototyping of complex components can be achieved. A nanometer precision linear motor, such as that described in Chinese national patent （patent No. ZL 98 2 16753. 9）, can be used to obtain the nanometer precision movements in the process. The process does not require mask, can be used for various rapid prototyping materials, to obtain high fabrication precision （its scale precision is 15 nm）, and larger ratio of height to width of micro/nano-structure. It can find widespread applications in the fabrication of micro-mechanism, trimming IC, and fabricating minilens, etc.

For any n 3. let R(n) denote the root category of finite-dimensional nilpotent representations of cyclic quiver with n vertices. In the present paper, we prove that R(n-1) is triangle-equivalent to the subcategory of fixed points of certain left (or right) mutation in R(n). As an application, it is shown that the affine Kac-Moody algebra of type n-2 is isomorphic to a Lie subalgebra of the Kac-Moody algebra of type n-1.

As remote control for electric home appliances thro ug h the Internet becomes more common, many compannies today launched a new corpora te initiative to develop advanced embedded solutions for Internet connectivity t hat can be applied to a boundless number of products such as information applian ces and non-PC devices. The most representative products are CMX-MicroNet which provides true TCP/IP ca pabilities for 8-bit and 16-bit microprocessors and eZ80Internet Engine which provides easy Internet connectivity for 8-bit devices. Pushed by the extraordinary success of these products, we have developped a kin d of embedded TCP/IP chip based on DW8051 *** some significant features su ch as establishing several connections at a same time, low-cost and high speed, we hope it will possess its own "embedded Internet" market. There are three most common application fields of the embedded TCP/IP chip. a) connection embedded microcontroller-based devices such as electric home appl iances to Internet b) allowing the remote control and monitoring of devices in the field via the In ternet c) allowing a remote device to send messages via email to, for example, a servic e centre. The working process of communication with embedded TCP/IP chip is described as f *** it starts to work, it keeps on waiting the connection request from t he host and getting the requisite information such as destination IP address,des tination port through the host *** it should connect to the ISP. A di al-up modem makes the connection and then the connection is negotiated. When bo th end systems begin to communicate, the chip keeps on transmitting datagram bet ween them and inspecting every phase of the connection to ensure the communicati on. The innovation of this design is the successful usage of separate CRC module and UART module, as can improve the speed and performance of this chip greatly. Suc h kind of efficiency improvement brought by the proposed design has been proved

In this study, the bacterial community structures in samples of ballast water collected from a ship from Singapore and of local sea water collected from xiamen Port were compared using restriction fragment length polymorphism (RFLP) and 16S rDNA sequence analysis. Except for dominant a-Proteobacteria that are common to both systems, the bacterial community structures of the two systems were quite different. Most of the clones derived from the different systems were grouped into different phylogenetic clusters, and the systems share only one common RFLP pattern. The ballast water, which is likely from clean offshore waters, contains sequences specific to aand c-Proteobacteria. Phylogenetic analysis revealed that the ballast water contained sequences belonging to attached bacteria and bacteria commonly found in the open sea, as well as many novel sequences. In addition, no known pathogenic bacteria were detected in the ballast water samples. Conversely, water samples from xiamen Port were apparently affected by the near shore environments. Specifically, in addition to aand c-Proteobacteria, water from xiamen Port contained band d-Proteobacteria, Synechococcus, Bacteroidetes and Actinobacteria, which are common in coastal environments. Additionally, four pathogenic bacterial sequences and one plasmid sequence of a potential red tide forming alga were detected in the water from xiamen Port, which suggests that the local sea water is polluted. The results of this study can be used as background information to assess the risk associated with the introduction of non-indigenous species to local systems and to establish ballast water management systems.

Robust Object Tracking under Appearance Change Conditions

引用

International Journal of Automation and computing 2010年第1期7卷 31-38页

作者： Qi-Cong Wang Yuan-Hao Gong Chen-Hui Yang Cui-Hua Li Department of computer Science, xiamen university, xiamen 361005, PRC Department of computer Science Xiamen University Xiamen PRC

We propose a robust visual tracking framework based on particle filter to deal with the object appearance changes due to varying illumination, pose variantions, and occlusions. We mainly improve the observation model and re-sampling process in a particle filter. We use on-line updating appearance model, affine transformation, and M-estimation to construct an adaptive observation model. On-line updating appearance model can adapt to the changes of illumination partially. Affine transformation-based similarity measurement is introduced to tackle pose variantions, and M-estimation is used to handle the occluded object in computing observation likelihood. To take advantage of the most recent observation and produce a suboptimal Gaussian proposal distribution, we incorporate Kalman filter into a particle filter to enhance the performance of the resampling process. To estimate the posterior probability density properly with lower computational complexity, we only employ a single Kalman filter to propagate Gaussian distribution. Experimental results have demonstrated the effectiveness and robustness of the proposed algorithm by tracking visual objects in the recorded video sequences.

This paper deals with the simple additive degradation models with single random effect. The authors further study the link between the aging property of the implied lifetime and that of the random variation. It is found that both the aging property of the random variation and the analytical behavior of the mean degradation path influence the aging behavior of the implied lifetime.
