S-system is a commonly used model for dynamic biological system. However, due to technical limitations, biological reaction networks are often only partially observable, which indicates that not all individuals incorporated in the model can be measured directly. Given a limited amount and quality of experimental data, it cannot be assured that the model structure and parameters can be estimated unambiguously...
The field of learning analytics has the potential to enable education institutions to increase their understanding of their students' learning needs and to use that understanding to positively influence student learning and progression. Analysis of data relating to students and their engagement with their learning is the foundation of this process. In this work we investigate the database of learners'...
This paper studied the modeling and simulation of the public opinion propagation in the small-world network. The public opinion information propagation characteristics were firstly analyzed, and different states of the people in the propagation environment were proposed. Based on that, this paper constructed the public opinion propagation model based on the agent modeling method, and proposed the...
We present a sport skill classification using time series motion picture data, focused on table tennis. We do not use body nor skeleton model, but use only hi-speed motion pictures, from which time series data are obtained and analyzed using data mining methods such as C4.5 and so on. We identify internal models for technical skills as evaluation skillfulness for forehand stroke of table tennis, and...
Human body communication (HBC) is expected to become a unique man-machine interface because the transmission path is established only when the user touches the target device. In this study, HBC between a stationary device and a wearable device worn on the wrist was investigated. Transmission characteristics between the devices and electric field around the human body model were calculated by electromagnetic...
The central pattern generator(CPG) is used to control robot very well. But the adjustment of CPG parameters and it's interaction with the external inputs are still open problems. Based on biological knowledge, the central nervous system rules the switch of the CPG modes. In this paper we focus on the coupling relationship between the cerebral cortex and the CPG and establish the mathematical model...
Forest canopy leaf area index (LAI) is an important biological parameter and an evaluation index of the vegetation canopy. It is difficult to get LAI through direct inversion using Li-Strahler geometric-optical model (GOMS)[1,2]. In this paper, LAI is introduced into the GOMS model as an independent variable to substitute other canopy structure parameters. The verification results well demonstrated...
In this paper, we concentrate on the problem of landscape evaluation which is of great importance in landscape design and construction. First of all, we present a landscape evaluation index system, which is made up of four kinds of indexes, such as "regional ecoenvironment", "social, cultural and residential environment", "man-made physical environment and ecocivilization...
Over the last fifteen years, computational intelligence applications have proliferated solutions to financial engineering problems, bringing a new fertile area of collaboration between professional engineering and financial communities. Computational systems based on machine learning techniques have become indispensable in virtually all financial applications, from portfolio selection to proprietary...
Combinatorial interaction testing (CIT) is an effective failure detection method for many types of software systems. This review discusses the current approaches CIT uses in detecting parameter interactions, the difficulties of applying it in practice, recent advances, and opportunities for future research.
Network theory has been used for modeling biological data as well as social networks, transportation logistics, business transcripts, and many other types of data sets. Identifying important features/parts of these networks for a multitude of applications is becoming increasingly significant as the need for big data analysis techniques grows. When analyzing a network of protein-protein interactions...
Global climate changes and human activities have a profound impact on disaster environment and formation mechanism of water logging disaster, exacerbating the uncertainty of water logging disaster and highlighting complexity and difficulty coping with the water disasters of farmland. A large number of researches on risk assessment and prediction of flood disaster have been carried out at home and...
This paper analyzes traditional architecture and functionality of English language education website, and points out that the lack of a client/server (C/S) network model. Peer to peer (P2P) system architecture is implemented in English language teaching website. This architecture does not only take full advantage of the computing power and communication bandwidth of each online node, but also provides...
In this paper, we study a modified Leslie-Gower predator-prey model with Holling II type functional response and harvesting terms. By means of the generalized continuation theorem, sufficient conditions for the existence of at least two positive periodic solutions of the model are established.
Application dependability issues depend on increasingly sophisticated activities during operation time for deployment, upgrade, scaling out/in and reactions to various failures. Traditional approaches to improving application dependability focus on artifact-oriented troubleshooting and improvements. In this paper, we present an approach using process models to represent and analyze operations with...
Landscape planning is based on science and art. Landscape planning is to do space planning, design according to coordinate relationship of man and earth, man and nature. Landscape planning take sustainable development as the basic goal. In modern landscape planning area, more and more high technology are combined with planning and design theory to solve practical problems. GIS provides a new method...
