A data hiding scheme with flexible hiding capacity applied in vector quantization (VQ) index tables was proposed by Chang et al. However the minimum bit rate of their scheme is 0.552. To improve the bit rate of Chang et al's method, this paper proposes a novel and efficient reversible data embedding scheme for VQ index tables. The proposed method exploits characteristics of VQ indices and uses two...
Multidimensional sequences are common, and measuring their similarity is a key to any analysis of such data. There is a wealth of similarity measures for sequences in the literature, but most of them are designed for a special type of sequence and later extended to more general types. These extensions are usually ad hoc, and the extended versions may lose the original conceptual interpretation of...
Set pair analysis method with five-element connection number was applied for a comprehensive evaluation of the beneficial effect of water-saving renovation in irrigation area. Taken inland irrigation area in the Yellow River, Huai River and Hai River region as an example, according to their characteristics in economic, social, cultural and environmental aspects etc., the index system for a comprehensive...
Addressing the characteristics that the ArcGIS has relatively weak support to China's standard drawing of basic scale map form, and is unable to generate marking information automatically and repeatedly use the same decoration elements, this article adopts the Element under ArcEngine components to implement the map decoration with1:50 000 plotting scale. The system can draw out the decoration contents...
Affinity propagation (AP) is a new powerful clustering algorithm based message passing between data points. One of the major problems in clustering is the determination of the optimal number of clusters. In this paper, we propose a new approach called Affinity Propagation Clustering based Particle Swarm Optimization (PSO-AP), which using Particle Swarm Optimization (PSO) algorithm to determination...
Wettability of growth media is an important practical factor in soilless culture. The study was conducted to improve the water absorbing ability for green waste compost (GWC) as growth media with wetting agent. The experiments were divided into two sections. First, compost maturity assessment was performed by germination bioassay using Lepidium sativum L. (cress) as an indicator and germination index...
In this paper, we propose an information hiding scheme to embed secret information into the compression code of an index table. First, the codewords neighboring the current processed index along with their closest codewords form a state codebook. Two indices of the state codebook are reserved as indicators. Once the current processed index satisfies some pre-defined conditions, the current processed...
In last two years, people have paid more and more attentions to price fluctuations. China Centre Bank frequently uses the approach of adjusting interest rates to influence price fluctuations. This article will introduce a monetary policy model that covers different time periods, different types of interest rates and policy disturbances. It also depicts durative and directional track of interest rates...
There are internal and external reasons for the occurrence of landslip. Through the analysis on a large number of investigation materials of landslip, the growth inducements of landslip are found out. By use of theories in blur maths, we conduct order arrangement of these inducements in accordance their significance, put forward blur judgment rule of landslip estimation and present applicable examples.
This paper proposes a novel data embedding method for embedding secrets into VQ indices by using the Chinese Remainder Theorem (CRT). In the experimental results, the hiding capacity is flexible which corresponds to the pre-defined prime parameters. In addition, a reversible mechanism is imported into the scheme so the original VQ indices can be restored after extracting secrets retrieval.
Time series data abound and analysis of such data is challenging and potentially rewarding. One example is financial time series analysis. Most of the intelligent data analysis methods can be applied in principle, but evolutionary computing is becoming increasingly popular and powerful. In this paper we focus on one task of financial time series analysis - stock price forecasting based on historical...
The information is an effective approach to raise the level of plant management in modern enterprises. Aimed at the problem that most of the enterprises face wire-monitoring, so starting with the work in plant running management and adopting the technology of WSN, and analyzes deeply the based on wireless sensor network in plant running management. By collecting plants states signal in WSN, get monitoring...
The third party logistics is a kind of service pattern, which produces under the outsourcing environment and gradually shows huge potential and vital status in the economic development. This paper constructed the index system and studied the core competence of third party logistics. With the usage of Analytic Network Process (ANP), the paper evaluated the criteria and alternatives in a feedback system...
This paper provided a new method to evaluate the priorities on location selection of the dry port. The factors that affect the facilities of the dry port were systematically analyzed and an evaluation model was built when considering the feed back and the relations between those factors. With the analytic Network Process, the dry port location is selected based on the index system in view of the factors...
In order to deal with the flaws of enterprise independent innovation capability clustering analysis method which can not computer complex distribution data, and sensitive to the initialization, and easy to fall into local optimum, and is artificially assigned the number of classes, a new method of dynamic fuzzy kernel clustering analysis based on artificial immunity is proposed in this paper. The...
