Authors: Wang Dong Xing , Chen Su
Published: July 2011

The subdivision based halftoning algorithm works in a statistical way. Analysis of its output shows that, error accumulation and rounding operation may produce big quantization error, and there may be artifacts in its output. Some improvements have been proposed. First, a procedure is added to find cases with big quantization error, and to solve the problem. Second, instead of propagating error sequentially as in the algorithm, propagating error along random directions has been tested to reduce the artifacts in the output. Third, propagating error along a direction, in which the quantization error of each subpart is the minimum, has also been tested to improve the output quality. Halftoning tests show that the improved algorithm produces clearer output than the original.

Authors: Li Yao Xiang , Jiang Li Chun
Published: July 2011

Earlywood microfibril angle (MFA) was determined at each growth ring from disks at breast height (1.3 m) from 6 dahurian larch (Larix gmelinii. Rupr.) trees grown in northeastern China. Significant variation in microfibril angle was observed among growth rings. MFA at breast height varied from 7.5°to 21.5°between growth rings and showed a descreasing trend from pith to bark for each tree. A second order polynomial equation with linear mixed-effects was used for modeling earlywood MFA. The LME procedure in S-Plus is used to fit the mixed-effects models for the MFA data. The results showed that the polynomial model with three random parameters could significantly improve the model performance. The fitted mixed-effects model was also evaluated using a separate dataset. The mixed model was found to predict MFA better than the original model fitted using ordinary least-squares based on absolute and relative errors.

A Flexible Query Answering Approach for Autonomous Web Databases
Authors: Meng Xiang Fu , Zhang Xiao Yan , Li Xiao Xi
Published: July 2011

Users often have imprecise ideas when searching the autonomous Web databases and thus may not know how to precisely formulate queries that lead to satisfactory answers. This paper proposes a novel flexible query answering approach that uses query relaxation mechanism to present relevant answers to the users. Based on the user initial query and the data distribution, we first speculate how much the user cares about each attribute and assign a corresponding weight to it. Then, the initial query is relaxed by adding the most similar attribute values into the query criteria range. The relaxation order of attributes specified by the query and the relaxed degree on each specified attribute are varied with the attribute weights. The first attribute to be relaxed is the least important attribute. For the relevant result tuples, they are finally ranked according to their satisfaction to the initial query. The efficiency of our approach is also demonstrated by experimental result.

The Application of Trellis Coded Modulation in Cooperative Communication Systems
Authors: Ren Guo Can
Published: July 2011

In this work, we first assume that the relay node and the destination are connected by the error-free backbond. This scenario is often seen in the situation of handover in the uplink in 3G system, where the signals of a user is combined in either the base station or in the radio network controller . Under this assumption, the decoding metric is derived. Unlike, the decoding metric in this work is based on the joint probability of the received signal at the relay node and the destination rather than the conditional probability of received signal at the destination given the decoding information of the relay node. Based on this decoding metric, the information related to the relay node is calculated and then sent to the destination for fusion according to the derived decoding metric. Thus, the relay node does not need to actually decode the transmitted signal from the source. Therefore, contrast to the HDF protocol, the coding delay can be greatly reduced in this case.

Study on the Flow Situations of Lightguiding Plates by Micro Injection Molding
Authors: Huang Chiung Fang , Lin Yi , Shen Yung Kang
Published: July 2011

This study investigates the flow characteristics of microinjection-molded lightguiding plates. This study also analyzes the position of melt fronts on lightguiding plates. Viscous heating, temperature and velocity distribution are utilized to analyze delay or advancement of the melt front experimentally and using three-dimensional (3D) numerical simulation. A slow injection speed reduces viscous heating. As viscous heating decreases, the temperature distribution decreases and plastic viscosity increases. A high plastic viscosity increases flow resistance and melt plastic velocity decreases. The advancing melt front of a lightguiding plate is delayed in this situation. The key of this research is that the plastic melt front can arrive the end position at the same time on filling stage of lightguiding plate for microinjection molding. In this research, the authors find increasing the injection speed can help the previous situation. Experimental results demonstrate that filling in the experiment is very close to that in 3D numerical simulation.

Published: July 2011

The melting and freezing with two different cooling rates of AgN (N= 140, 360, 532, 784, and 952) nanoclusters are simulated by using molecular dynamics technique with the frame work of embedded atom method. The potential energy as a function of temperature is obtained and the structural details are analyzed. The results reveal that the melting and freezing temperature increases almost linearly with the atom number of the clusters except for Ag360. All the silver nanoclusters have negative heat capacity around the phase transition temperature, and the clusters with slow cooling rate have icosahedral structure at 300 K.

Published: July 2011

This paper addresses the performance of pseudorandom Binary Amplitude Shift Keying (BASK) emission sequences for an ultrasonic multi-life location system in rescue robot. To improve the performance of multi-life location system, the BASK modulation were used to construct the spread spectrum emission sequences for ultrasonic sensors. Correlation technique in the receiving circuit was used to de-spread. Good correlation characteristics, i.e., sharp autocorrelation and flat cross-correlation, can help eliminate crosstalk between multichannel ultrasonic sensors. To improve the echo signal correlation effect, genetic algorithm was applied to optimize pseudorandom m sequences. In simulated post-earthquake environment, experimental verification of ultrasonic multi-life location system consisting of eight-channel SensComp 600 series electrostatic sensors with optimized BASK emission sequences was carried out. The experimental results demonstrate that the ultrasonic multi-life location system with the proposed method can realize multi-life location simultaneously.
