In order to optimize the capacity of farmers' income persistently increasing, in this paper we analyze 8 factors affecting farmers' income increasing using PLS model based on the statistical data of Heilongjiang reclamation from 2000 to 2008. The study shows that wage incomes, agricultural subsidy and tax reducing still account for a great proportion of farmers' net incomes, but the level of agricultural...
Operating municipal infrastructure projects are a special operation model that the Government and the project investors achieve the operating infrastructure projects by signing infrastructure concession contracts. This paper is aimed at the feature of operating infrastructure projects to achieve the objective of maximizing the value of the projects, under the conditions the concession period and the...
The paper makes analysis of the optimal currency composition of international reserves based on Markowitz mean-variance model using Monte Carlo simulation for solution. We calculate US dollar and Euro as the two major reserve currencies for 2007 through 2009, which is also the financial crisis stage. The model suggests to decrease US dollar in late 2007 and to increase US dollar in mid 2008. Our findings...
This paper introduces a DSP optimization model based on data structure transformation and memory schedule for real-time image process. This model implements 4 critical methods: image block, image dimension reduction, DMA transfer and ping-pong cache, which makes use of DSP hardware feature and optimizes the data schedule among the external and internal memory and CPU, while processing 2D digital signal...
RNAi is a naturally occurring, highly conserved phenomenon of RNA mediated gene silencing among the multicellular organisms. Currently, RNAi has been successfully applied in functional genomics, therapeutics and new drug target identification in mammals and other eukaryotes. The uniqueness lies in sequence specific gene knock down which made RNAi an indispensible technology. In the mechanism of RNAi,...
Recently, the ant colony optimization (ACO) meta-heuristic has received more attention as an efficient searching method for feature selection. This paper addresses various solution representation schemes of ACO and their effectiveness with respect to whether they consider correlations between features. A generic code of ACO using on-edge representation is presented. The paper formulates the ??-component...
Limited feedback in multiple antenna wireless systems is a practical technique to obtain channel state information at the transmitter. When the channel is time-varying with memory, however, selected codeword may become outdated before its use at the transmitter. To overcome this problem, we propose a Grassmannian prediction and predictive coding framework for delayed feedback systems by exploiting...
Most of the biclustering algorithms for the analysis of high dimensional gene expression data use some distance measure or correlation coefficient between a pair of genes as the similarity measure. These measures capture only linear relationships between the genes but non linear relationships may exist amongst them. Mutual information is a more general measure to investigate relationships (positive,...
We present a new stereo matching algorithm using epipolar geometry. The proposed algorithm does not completely rely on the fundamental matrix for the identification of the corresponding pairs. In fact, it uses epipolar geometry to locate the corresponding epipolar line in the other image in order to reduce the search space from the whole image plane to just one-dimension. A search window around the...
