Authors: Li Chang Sheng , Zhang Wen Qi
Published: October 2014

The primary objective of this paper is to explore how formal credit constraints affect farmers’ efficiency by the 743 random farmer samples from Jiangxi province in China. The statistic analyses of their individual characteristic, together with the inputs and outputs of their production shows that the constrained value of the production of the credit is RMB 563.2 yuan which is RMB 190 yuan less than those who are not credit constrained. The samples are divided into two groups, the one group with farmers who have been constrained by the formal credit while the other has not. The empirical results of the stochastic frontier production functions show that the agricultural production efficiency is not only affected by the labor and land, but also associated with the formal credit constraints. The results also reveal that efficiency loss of the credit constrained farmers is 17.8% higher than those of the unconstrained farmers. By doing this research, we have got evidence which clearly shows that formal credit constraints do distort the agricultural inputs, and by alleviating formal credit constraint, it is greatly helpful to improve the efficiency of agricultural production.

Simhash for Large Scale Image Retrieval
Authors: Guo Qin Zhen , Zeng Zhi , Zhang Shu Wu , Feng Xiao , Guan Hu
Published: October 2014

Due to its fast query speed and reduced storage cost, hashing, which tries to learn binary code representation for data with the expectation of preserving the neighborhood structure in the original data space, has been widely used in a large variety of applications like image retrieval. For most existing image retrieval methods with hashing, there are two main steps: describe images with feature vectors, and then use hashing methods to encode the feature vectors. In this paper, we make two research contributions. First, we creatively propose to use simhash which can be intrinsically combined with the popular image representation method, Bag-of-visual-words (BoW) for image retrieval. Second, we novelly incorporate “locality-sensitive” hashing into simhash to take the correlation of the visual words of BoW into consideration to make similar visual words have similar fingerprint. Extensive experiments have verified the superiority of our method over some state-of-the-art methods for image retrieval task.

Uniform Variance Product Quantization
Authors: Guo Qin Zhen , Zeng Zhi , Zhang Shu Wu
Published: October 2014

Product quantization (PQ) is an efficient and effective vector quantization approach to fast approximate nearest neighbor (ANN) search especially for high-dimensional data. The basic idea of PQ is to decompose the original data space into the Cartesian product of some low-dimensional subspaces and then every subspace is quantized separately with the same number of codewords. However, the performance of PQ depends largely on the distribution of the original data. If the distributions of every subspace have larger difference, PQ will achieve bad results as shown in our experiments. In this paper, we propose a uniform variance product quantization (UVPQ) scheme to project the data by a uniform variance projection before decompose it, which can minimize the subspace distribution difference of the whole space. UVPQ can guarantee good results however the data rotate. Extensive experiments have verified the superiority of UVPQ over PQ for ANN search.

Authors: Li Zhi Qiang , Tan Yuan , Guo Hong Chen , Feng Chong
Published: October 2014

In recent years, the prevailing topic crawler algorithms are concentrated on the contents of topical words. These existing approaches neglect the sematic relationship among textual concepts, which lead to low correlation between crawled webpages. To address the issue, this paper presents a deep analysis of Shark Search algorithm, and makes an optimization in terms of incorporating the characteristics associated with semi-structured webpages. Furthermore, we enhance the performance of vector space model utilized in Shark Search algorithm by virtue of domain ontology, and propose a standardized method based on the vector space of ontology model to improve the evaluation metric of TF-IDF. The experimental results demonstrate the effectiveness of our algorithm that outperforms the state-of-the-art significantly in precision and recall.

Published: October 2014

The dynamic viscoelasticity of the outer and inner part of bamboo with different ages was investigated using Dynamic Mechanical Thermal Analyzer (DMA). The results showed that,storage modulus (E’) and loss modulus (E’’) of both outer and inner part of bamboo were increased at temperature between 25-250°Cas the bamboo ages increasing. In addition, E’ and E’’ of the outer part of bamboo were higher of the inner part with the same bamboo age. Also a significant loss peak in E’’~T curves between 190-210°C was found. The peak values of E’’~ T curves of the outer part only shown slight variation with bamboo age increasing. However, significantly different of peak values was found in the inner part. This was caused by the difference of the chemical composition in outer and inner part of bamboo with different ages. The width of E’’ peak varied slightly in outer bamboo of different ages, but in the inner part , it was increased as the age increasing. This revealed that in the outer part of different ages, the chemical composition of the molecular values was closer, In the inner bamboo, it was increased as the age increasing..
