Ultra high speed injection molding plays a more significant role in molding thin-wall part in recent 3C products. Systematic studies on the proper molding window of Secure Digital (SD) card housing of 0.25 mm thick using ultra high speed injection molding have not yet been reported. In this study, a proper molding window for SD card housing using ABS and HDPE by varying mold temperatures from 30 °C to 100 °C and injection speeds from 100 mm/sec to 1200 mm/sec was investigated in details. Molded dimension and weight were measured experimentally. It was found that higher mold temperature and faster injection speed are two critical molding parameters that leading to good moldablilty for SD card housing.

A novel Lagrangian ¿individual-based¿ isotropic continuous time exponential type stochastic swarming model in an n-dimensional Euclidean space with a family of attraction/repulsion function is proposed in this article. The stability of aggregating behavior of the swarms system are verified by stability theoretical analysis and numerical simulation. Stability analysis and numerical simulations results further indicate that the individual members living in group during the course of coordinative motion can realize the mutual aggregating behavior, the motion of each individual member is a combination of the inter-individual interactions, meanwhile, which are also presented to demonstrate the effectiveness of our model. The attraction/repulsion function is odd, so the attractive force and repulsion force taking effect in opposite direction that leads to aggregation behavior. Moreover, numerical simulation results of globally asymptotically stability analysis also verify the capability of the proposed relevant theories.

De novo prediction of protein structures, structures prediction from amino acid sequences which are not similar to those of hitherto resolved structures, has been one of the major challenges in bioinformatics. A new prediction protein structure method based on Genetic Algorithm and Coarse-grained protein model is presented. Genetic Algorithm is a high performance optimization method and can effectively assemble a separate sequence, and Coarse-grained protein model have consistently assembled fragments are dynamically searched by Langevin molecular dynamics of conformational change. This new method combines the advantages of Genetic Algorithm and Coarse-grained protein model, which will improve the accuracy of protein structure prediction.

Based on the Ethernet and Bluetooth wireless technology, an improved Bluetooth Ad Hoc network structure, WBPAN(Wireless Bluetooth Personal Area Network) is proposed for the streaming media distribution. In WBPAN, each Bluetooth AP acts as the root of the Bluetree and connects with the nearby Bluetooth devices by the modified BlueTree formation algorithm. In WBPAN, we propose the layered and scalable streaming media distribution architecture and construct an AP Overlay network where the route addressing, the joining in and the exiting are implemented dynamically, basing on the Distributed Hash Table (DHT) and P2P technology. The simulation shows that the Bluetooth terminal can access the media stream data from the proper AP more smoothly, the quality of service of the stream media is improved markedly and the payload of the source server is reduced significantly under the WBPAN architecture.

We investigate the evolution of microstructure and mechanical properties of sputter-deposited Al/Nb multilayers with miscible fcc/bcc type interface and individual layer thickness, h, of 1-200 nm, subjected to helium ion irradiations: 100 keV He+ ions and a fluence of 6 10 16/cm2. Helium bubbles, 1-2 nm in diameter, are observed. When h is greater than 25 nm, hardnesses of irradiated multilayers barely change, whereas radiation hardening is more significant at smaller h. Transmission electron microscopy and scanning transmission electron microscopy studies reveal the formation of a thin layer of Nb3 Al intermetallic phase along the Al/Nb interface as a consequence of radiation induced intermixing. The dependence of radiation hardening on h is interpreted by using a composite model considering the formation of the hard Nb3 Al intermetallic layer. © 2009 American Institute of Physics.

Entity relation extraction is an important research field in information extraction. In this paper, a machine learning algorithm that use maximum entropy to extract relations between entities in the filed of tourism is proposed. We consider comprehensively the syntactic context information, entity types, vocabulary, part of speech information and their combination features, and focus on selecting suitable feature in the field of tourism in order to build the classifier of entity relation extraction. We do our experiment on the artificial collection of 600 corpuses in the field of tourism. The methods used in this paper receive a good result in the identification of two types entity relation, The F values reached 81.21% and 78.46% respectively. Comparing with two groups of experiments, we can conclude that combination features can effectively improve the accuracy of the maximum entropy classifier's model. 1553-9105/ Copyright © 2009 Binary Information Press.

A new vector particle swarm optimization (NVPSO) is proposed to solve constrained optimization problems in this paper. In NVPSO, we introduce a shrinkage coefficient to ensure that all dimensions of a particle are within lower and upper bounds, and a new function to determine whether the particle is within the feasible region. One-dimensional search optimization methods are selected in NVPSO algorithm to produce a new position which is guaranteed to be in the feasible region for the particle which escapes from the feasible region. The whole process is dealt as vector mode. The experimental results show that the principle of NVPSO this paper proposed is simple, relatively effective and efficient.

An aggregation tree approach for event detection in wireless sensor networks

Collecting data with confidence of the environment is an important application of the wireless sensor networks (WSN). In this study, we used a splay tree based event region fault-tolerant detection algorithm (STERD) for WSNs to address these problems. Rather than passing large quantities of raw data through the network, our network instead sends the coefficients of a regression polynomial that simulates the readings of the sensor nodes throughout the region of interest. These coefficients essentially summarize the relevant information over the region, in effect compressing the data, leading to a reduction in both data volume and energy expenditure. Simulation results indicate that the proposed STERD can attractively obtain the high event region detection accuracy and considerably reduce the false alarm probability. © 2009 ACADEMY PUBLISHER.

In order to improve the imaging quality of conventional laser photography, this study proposes a new system for colored pulse laser photography to obtain high speed color microscopic imaging. Based on the RGB synthesis technique, three channels of red, green, and blue images are acquired from three cameras with three independent laser light sources. Then, a high quality color image can be obtained by assembling the monochromatic images with the image realignment and color calibration processes. The experimental results show that the proposed system can achieve a high quality colored pulse photography.
