A cellular automata model (CAM) is presented to simulate the passenger evacuation of carriage in an emergency. Some special algorithm is introduced considering simple human judgment to make the rules more reasonable. Based on the above model, a program CARUN is developed. Considering the special geometry and boundary conditions, the simulation of the evacuation process for the passenger in carriage...
In this paper, a gait recognition algorithm based on multi-resolution regional shape context is proposed. Taking binary silhouettes as input, according to human anatomy knowledge, some key joints on human body are selected, then the shape context which counts regional pixel with multi-resolution and different support region, is used to extract the environmental characteristics of these joints, finally...
The information from Internet and the acceptance of offers are uncertainty in e-commerce, so this work presents a model using fuzzy logic to support bilateral agent negotiation. In the model, a negotiation can be made only if there exits a zone of agreement between the retentive offers of participants. We assigned approximate weight to different issues of an offer based on their importance degrees...
In video human action recognition of the continual human motion is a difficult point for application. The method of human action recognition based on latent-dynamic condition random fields is presented. By star form distance descriptor of human body contour, human pose is extracted. Then in continuous sequences method building the model of LDCRF shows the mapping relation between action feature and...
This paper shows how designers use Shape Grammar to create shape and form in tractable manner. The Shape Grammar was developed in an article by Georgy Stiny and James Gips in 1970. Using the approach of Shape Grammar can generate large design solution spaces and get a lot of possible results. The parametric shape grammar provides an effective way to extend design ideas in the process of transportation...
Virtual human body model is important of the products for the ergonomics optimization design. In this paper, a virtual human body model was built using SolidWorks software. The function ??configuration manager?? in SolidWorks makes serial rebuilding of virtual human body models easy without reimporting the models with different dimensions many times. Therefore, it becomes efficient and convenient...
Asset assignment and scheduling algorithms were developed and implemented to support a team-in-the-loop planning experiment conducted at the Naval Postgraduate School (NPS) in March 2009. The experiment examined planning and information flows among three cells in an abstracted and simplified Maritime Operations Center (MOC). This paper describes two optimization-based modules that focused on the Future...
This paper presents a new method for modeling driver operation behavior. The proposed method is based on using the predictor coefficients as feature vectors extracted from driving operation signal by linear prediction analysis (LPA). The distribution of the feature vectors is captured by employing auto associative neural networks (AANN) model. The performance of the model was evaluated through driver...
According to Maslow's theory on human needs, this paper has analyzed the different kinds of psychological needs which game-players expect to be met when they playing online-games, then built a needs model of online-game from the perspective of players, so as to provide guidance on game-design for the developers and help bring experience for the players.
First, the paper sets up the value chain model of construction enterprises; second, the paper combines value chain with core competence, constructs evaluation index system of construction enterprise's core competence from the perspective of intellectual capital; third, the paper constructs a comprehensive evaluation model of construction enterprise's core competence used the method of unascertained...
Advances in bioengineering have led to increasingly sophisticated prosthetic devices for amputees and paralyzed individuals. In this work, a virtual human hand (VHH) is designed for prosthesis use and described in details. EMG-driven VHH is to be made of open source code, low cost, modular and flexible in structure. The custom-made nature of VHH allows us to refine and develop it further to mimic...
This article constructed a measurement model of human resource management quality (HRMQ) from the perspective of total quality management (TQM) and enterprise internal service management quality, testing the validity of the model based on 326 enterprises' samples which collected by a questionnaire developed by the author independently. The result showed that HRMQ could be appraised form the level...
Emergency management of food safety accidents is one field that emergency academics and practices have put emphasis on in the recent years. Sanlu milk powder scandal, an extraordinarily large food safety accident occurring on September, 2008, raised questions about emergency management model for improving the performance in emergency management of food safety accidents. This paper aims to construct...
The traditional principal agent relationship is studied under the agent's rationality and ability homogeneity. In fact, agent's behaviors are affected by their psychological bias, and there exists heterogeneity in the agent's abilities, which can affect the firm output. Thus, the agent's ability and overconfidence bias are introduced into the principal agent relationship. Through the optimal contracts...
Web Services and grid-enabled scientific workflows are of paramount importance for the realization of efficient and secure knowledge discovery scenarios. This paper presents a Grid-enabled Genotype-to-Phenotype discovery scenario (GG2P), which is realized by a respective scientific workflow. GG2P supports the seamless integration of SNP genotype data sources, and the discovery of indicative and predictive...
A new multi-agent automated negotiation model is developed and evaluated, in which two competitive agents, such as the buyer and seller, have firm deadlines and incomplete information about each other. The negotiation is multi-dimensional in different cases. The model improves the model of Wooldridge and that of Sycara to a certain extent. An e-commerce model based on multiagent automated negotiation...
This paper presents a new technique for action recognition in video using human body part-based approach, combining both local feature description of each body part, and global graphical model structure of the human action. The human body is divided into elementary points from which a Decomposable Triangulated Graph will be built. The temporal variation of human activity is encoded in the velocity...
With the theory support of "the first law of geography" the spatial variance of the land use landscape in Haidian District of Beijing is analyzed with the geostatistic tool and grid sampling method. The spatial organization and mechanism of urbanization can be well understood by the reveal of spatial characteristics of artificial impact and ecological effect. The results show that: (1) the...
IT ecosystems are ultralargescale software systems that consist of various, constantly interacting and partly autonomous subsystems as well as the users of the overall system. Because of their strong integration with everyday life, these systems are often not even perceived as IT systems by its users. This is a problem for requirements engineering, as users might not know of or may not be interested...
The human eye is able to locate objects or regions of importance in its field of vision. Many visual saliency models have been proposed to replicate the human visual system (HVS) in detecting salient objects in a visual scene. A colour space transformation from the RGB space is assumed to increase the detection performance, given the reason that the transformed colour space would allow a better representation...
