The bio-inspired geomagnetic navigation is inspired from animals navigation behavior which dispense with the priori geomagnetic data. It can be employed by AUV for a navigation task that arrived to targeting point which is characterized with geomagnetic multi-parameter through magnetotaxis searching behavior. However, the geomagnetic anomalies area could form an extreme value region and disturb the...
Traditional Chinese medicine (TCM) is a holistic medical approach and the formula's composition discipline is still a mystery. Detecting a formula's structure and herb communities/clusters in TCM Formula networks (TCMF) is a mainly existing problem in data mining of the data sets. In this paper, we devise a novel community similarity calculating method in the process of clustering, which is called...
E-healthcare systems of Wireless Body Area Network (WBAN) promise enormous change in future healthcare industry. The system generally consists of multiple sensor nodes that monitor various medical signals and deliver data to a network coordinator for further processing. One of the major issues of such systems is energy efficiency, owing to the limited power supply and difficult replacement of batteries...
Dependence on the prior magnetic map become one of the key problems which restrict the development of the geomagnetic navigation. This paper inspired from the animal navigation behavior which dispense with the priori geomagnetic map. First, we generalize the bio-inspired navigation process as a multi-objective problems. Then, present a stress evolution search AUV navigation model for the particularity...
Robust small target detection of low signal-to-noise ratio (SNR) is very important in infrared search and track applications for self-defense or attacks. Consequently, an effective small target detection algorithm inspired by the contrast mechanism of human vision system and derived kernel model is presented in this paper. At the first stage, the local contrast map of the input image is obtained using...
This paper presents a bio-inspired search behavior model for navigating using geomagnetic information in unknown environments. A multi-objective search navigation framework combining random walk movement model and stress evolution algorithm is applied to the navigation. Firstly, motivated by animal geomagnetic navigation behavior, we generalize the bio-inspired navigation process as the convergence...
Economy in coastal cities plays an important role in China. It is urgent to protect environment with economy developing. Four types of sea water quality can be regarded as states of Markov Chain. Transfer probability is viewed as the function of sewage and investment in environmental protection. Based on historical datum in Tianjin, the function is estimated by Random Forest. Given objective of sewage...
Technology innovation is the important factor about private enterprise's survival and development. To the private enterprise, the necessity of transformation firstly comes from its own developing requirements. Extensive developing mode which once played leading role in private enterprise hasn't been meet the requirements of economic development. On the other hand, this necessity also comes from market...
Portfolio with one risk-free and one risky assets was explored in \cite{BT1995, LO1999, SS2000, Gomes2005, Bassett2004, DGP2008, BG2009, HZ2009} for risk averse investors. Most of them, for example, \cite{BT1995, LO1999, SS2000, Gomes2005, Bassett2004, DGP2008} focus on empirical or numerical studies, except for some optimization problems solved simply by heuristics. Some analytical treatments have...
The N-terminal tails of the core histones are subject to mutiple covalent modifications. The histone code hypothesis suggests that multiple histone modifications act in a combinatorial fashion to affect gene transcription. To investigate the combinatorial patterns of histone modifications at the promoter region of gene, Bayesian network method was used to analyze the causal relationships among 12...
In this paper, we first established the coastal urban ecological economic development index system. Then using factor analysis and stochastic frontier approach, the coastal zone urban ecological economy input-output efficiency was analyzed. The results could provide theory basis for coastal urban ecological economic development research.
Modern golf presented in China has more than 20 years. With the rapid economic development and the growing number of golf enthusiasts prodded, the golf courses in China grow gradually, and the golf industrial-scale shapes preliminarily. Scientific forecast of the scale of golf courses has important significance for rational planning the development of golf industry. Based on the size of golf history...
Considering comprehensively of the actual development of the national economic and technological development zones in China and the availability of the evaluation data, the paper used data envelopment analysis (DEA) and stochastic frontier analysis (SFA) to evaluate the economic efficiency of China's national development zones with different input and output indicators. The article had come up the...
In China, IPO underpricing phenomena attracts more and more attentions. This paper constructs a structural system of equations and uses the instrumental-variables method to analyze IPO underpricing of the full-circulating stocks. Our empirical findings that those IPO underpricing and initial turnovers are negatively correlated support the hypothesis of speculative bubbles. The IPO underpricing is...
This paper measures companies' credit risks and qualitatively analyzes the relationship between credit risks as well as capital structures by calculating the distance to default of listed companies. It draws a conclusion that the corporate credit risk correlates closely to corporate capital structure ratio. The more liabilities of a company are, the less possibility for it to repay its debt will be,...
With the expressway network density increasing and high-speed railway opening, the transport service capacity grows fast, which also leads to more and more intense competition of various passenger transports. In this paper, we build the passenger transport model and also add Metrics in LOGIT model based on the selection of all travel methods, in considering the influence of traveler income, trip purpose...
Stream processing is an important emerging computational model for performing complex operations on and across multi-source, high volume, unpredictable dataflows. We present Flow, a platform for parallel and distributed stream processing system simulation that provides a flexible modeling environment for analyzing stream processing applications. The Flow stream processing system simulator is a high...
Limitation in concept and practice hinders the development of postgraduate education in our country. It is an important issue to break up enclosed situation in postgraduate education in terms of concept and specific education practice, so as to reconstruct a postgraduate training model that adapts to development of society and our country. The paper puts forward an open training model combining postgraduate...
The paper analyzes the construction condition and influencing factors of the concrete dam, and then constructs a block election model, which uses object-oriented simulation methods to model the construction of concrete dams. On the foundation of the preliminary research, a simulation and decision support system for concrete dam construction based on object-oriented is established to support decision-making.
