The intensive and fast development of livestock farming with ecological pattern of raising-biogas-irrigating is widely applied in China. After anaerobic fermentation the agricultural wastes can provides clean energy. However, there is problem by lacking of land to digest the biogas slurry. Based on livestock wastewater from a dairy farming, the experiment used modified two-stage anoxic/oxic (A/O)...
We propose a variant of the well-known Lenstra, Lenstra, Lovász algorithm (LLL) for MIMO detection in this paper, which is called random selection LLL (RSLLL). Not like the original LLL algorithm which sequentially searches through the whole basis, the new algorithm takes a random selection of the next pair of columns for LLL reduction. The proposed algorithm is proved to finish within finite number...
Based on the static factor analysis of innovation for a master's degree thesis database, a innovation evaluation method is employed to build the factor set, evaluation set, weight sets and fuzzy evaluation model using analytic hierarchy process and fuzzy synthesis evaluation method. The innovation of a master's degree thesis database is evaluated, and the effectiveness of this method is demonstrated...
Evaluation of groundwater environment carrying capacity is a multi-objective, multi-criteria and multi-level comprehensive issue. Evaluation index system of groundwater environment carrying capacity was built and divided into some subsystems in accordance with each index's inherent stratification link. Every index's effect on carrying capacity system was obtained by normalization operations catastrophe-based,...
In order to represent fuzzy concept in water quality assessment, the Nemerow Pollution Index and Vague sets similarity measure formula were integrated together, consequently a new water quality comprehensive assessment model was formed. The new formed model can well express fuzzy concept in water quality assessment. Choosing water quality inspection data at Chengdu city's Fu Nan River as analysis...
It is a multi-objective, multi-criteria, multi-level and high-dimensional comprehensive issue to assess groundwater resources and environment carrying capacity affected many factors. Projection pursuit (PP) technology was adopted to reduce dimension of the above non-linear and high-dimensional problem. Particle swarm optimization (PSO) algorithm was introduced to optimize projection index function,...
The JZ-curve, a new graphical expression of the gene sequence, is introduced. This representation not only avoids the limitations associated with crossing and overlapping, but also retains the biological information of gene sequences. At the same time, we constructed a new characteristic matrix, named J/J matrix. Simultaneously, the J/J characteristic matrix based on JZ-curve can describe the chemical...
A thorough research having been done on the previous researches in this field, the internal relationship between the highway post-evaluation indicator systems is figured out. In this paper, a comprehensive and systematic method is proposed to do the highway post-evaluation by using the structural equation model and the indicator systems and models are also construed. The results of the theoretical...
The ecological footprint (EF) per capita and human development index (HDI) of Shandong province from 2002 to 2007 are calculated, and the sustainable development level of Shandong province is evaluated quantitatively. The results show that the ratio of ecological footprint demand and supply has increased from 4.30:1 to 6.70:1 during the six-year period. The ecological footprint of fossil energy land...
The delay and stagnation of supply chain resulting from emergency can cause serious economic losses and credit problems. Therefore, there is need for corporations involved in the supply chain management to plan ahead for emergency situations. This is with a view to coping with the emergency promptly and effectively. To achieve this, the emergency plan should be evaluated accurately and objectively...
In this paper an information entropy assessment measure of supply chain system risk and a decision-making method based on combined fuzzy weight and entropy weight in which the input of score matrix are triangular fuzzy numbers are proposed. The individual's intuitive attitude toward risk is just reflected by the fuzzy weight measure of risk. An index system under supply chain risks is established...
Packet classification has been widely used in network security protection. A number of the major techniques for network security protection, such as virtual private networks (VPN), firewalls, and network intrusion detection systems (NIDS), are all dependent on the speed and ability of packet classification. The complexity of multi-dimensional packet classification will result in large scale rule-sets,...
Based on the static factor analysis of engineering for a master's degree thesis database, the fuzzy synthesis evaluation method is employed to set up the factor set, evaluation set, weight sets and fuzzy evaluation model. And engineering of a master's degree thesis database is evaluated, and the effectiveness of this method is demonstrated with applicable examples.
This paper first gives a new validity function for fuzzy clustering, then presents a method of the optimal selecting of the cluster number in the standard fuzzy c-means clustering algorithm, and finally outlines the fuzzy c-means clustering algorithm with parameters self-adapted. Experimental results carried on synthetic data set and data set based on actual background illustrate the performance of...
In this paper, the city input-output efficiency analysis which includes electric power input has been done based on the extension models of DEA to Chinapsilas typical cities. At first, it established index system of comprehensive evaluation of city efficiency, and did input-output-effectiveness evaluation which include electric power input for China's 23 cities in 2006 and sorted by the urban development...
Shape inspection of hatching eggs is an important and hard work in farms. Manual inspection lacks of objectivity and is time-consuming. An automatic shape identifying method was proposed based on machine vision, moment technique and improved GA-NN algorithm. Egg form index and radius differences are extracted as eggs shape feature parameters. An improved immune GA algorithm is put forward to optimize...
