This paper introduces a new method for analyzing Mass Violence Events, and then we make use of Intelligent Artificial and Agent-Based System to deal with them. In the meanwhile, we describe and defy three kinds of agents (cops, activists and civilians), what comes next is that we apply these theories to model and simulate such events. The simulation results show that the behaviors of activists can...
A 3D face recognition method is proposed. For feature extraction, 3D point set is divided into number of slices to be projected on the central planes parallel to the slices. Feature vectors are formed by approximating best fitting polynomials for data on the planes. A multimodal approach in the score level and corresponding distance metrics for both unimodal and multimodal cases are presented.
Iris segmentation is a component of iris recognition system, and noncircular iris is hard to segment accurately. This paper presents an iris segmentation algorithm using linear basis function and RANSAC (Random SAmple Consensus) which iterately derives fine iris boundary curves from coarse iris boundary points. The algorithm consists of three steps. In step 1, coarse center and radius of iris are...
In order to reduce the searching space of shape context matching method and improve the speed of silhouette matching, a matching method based on partial body silhouette is proposed. In this method body silhouette is divided into segmentations according to the principle of human body composition, and then match the representative silhouettes under the restrictions of limbs silhouette characteristic...
Regulation of cell growth and proliferation has a fundamental role in tissue development, organogenesis, and disease progression. Conserved distribution of the number of sides of cells with a mean value of six was found in a variety of proliferating epithelia. Previous studies have shown that clones of proliferating cells bounded by quiescent cells have fewer sides than normal epithelia. However,...
This paper presents a novel mechanism to implement caterpillar-like locomotion. First, the caterpillar-like locomotive pattern in nature is investigated and analyzed systematically. From a biological point of view, caterpillar locomotion can be abstracted as a body wave, called half wave. It is simple, but efficient. In this paper, a novel control mechanism, maintaining the half wave property, is...
the example-based method for generating realistic, controllable human models was presented. Users are assisted in automatically generating modifying an example body data by controlling the parameters provided. The examples from the Poser and 3D Max is preprocessed as templates. The modeling method learns from these examples the correlation between the parameters and the body geometry. After this learning...
Recently, urban sprawl becomes common phenomenon overseas and in domestic. Urban sprawl is a discontinuous development pattern and impacts on environment, economic and social aspect, including landscape fragmentation, species decrease, bio-diversity decrease and habitat destruction. Many researches indicate the relationship indeed exists between transportation accessibility and urban sprawl. The raise...
In this study, in order to investigate the wave-induced buoyancy effects, experimental studies were conducted on pontoon-type floating structures. A series of small-scale tests with various wave cases were performed on the pontoon models. A total of four small-scale pontoon models with different lateral shapes and bottom details were fabricated and tested under the five different wave cases. Six hydraulic...
In marine harvesting, fish waste due to the discards of non-targeted species represent a risk for the sustainability of fisheries, a loss of potentially valuable living resources and a threat for the ecological equilibrium. The project FAROS aims to develop and implement an efficient, integral management network for discards, to reduce global impact of this established practice, while putting in value...
The objective of this study was to introduce a new high-performance diameter distribution function. The long-term repeated measurement data sets, consisted of 150 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used. R distribution had presented a more accurate simulation than three-parametric Weibull function. The parameters p, q...
Based on the status from Dengkou County in Inner Mongolia, forestry pictures and measurements of plants situation were obtained by air-view photography. In 2006, nearly 130 photos of Wulangbuhe desert were taken in Dengkou County, and with the aids of GPS 10 bands of air routes had been operated with three-angel measurement methods. A view map in 1 sg KM under the scale of 1:1000 came to shape after...
A new dynamic 3D scene retrieval approach is proposed based on a novel dynamic Bayesian network (DBN) lightfield descriptor. To overcome the disadvantages of the existing 3D scene retrieval methods, we explore dynamic Bayesian network for building a new lightfield descriptor. Firstly, dynamic 3D object is put into lightfield, and many gray-views can be obtained along a sphere, and then features can...
Interactive robots are required to have minimal footprint on the shop floor and to be able to work in constrained areas while ensuring the safety of the humans. To this end, modeling of an unstructured environment including the humans is an indispensable part of the online control schemes deployed in such robots. In this regard, a new approach is proposed for generating an efficient model of the human...
The Dirichlet Process Mixture (DPM) models represent an attractive approach to modeling latent distributions parametrically. In DPM models the Dirichlet process (DP) is applied especially when the distribution of latent parameters is to be considered as multimodal. DPMs allow for uncertainty in the choice of parametric forms and in the number of mixing components (clusters). The parameters of a DP...
Two dimensional human body pose modelling system detects the human body parts, estimates their posture and then models them in an image plane using specified shape. In this paper, two windowing techniques are presented and then compared for the human head and torso pose modelling. The first technique, namely Windowing technique I estimates the torso followed by the head of the human. In this technique,...
In order to study the impact of different shapes of thread section on inverse identification, the technique of parameter inverse identification based model contrast methodology was conducted in this paper, and the thread material parameters of rectangle section was identified, and then this set of parameters was adopted in finite element model with thread section shape of triangle, zigzag and trapezoid...
In this paper, the off-line Chinese character image is transformed into ellipse shape of basic Chinese characters strokes in different position. The stroke "turning" and joint or crossover of strokes is combined by basic strokes. The neural network for extracting Chinese character has been build up. The research on off-line Chinese character image is transformed into the research on double...
Based on the theoretical principles of Kuznets hypothesis, this paper firstly proposes the Kuznets hypothesis of energy consumption. Empirical analysis in China's 29 provincial regions shows that: The current situations of China's provincial regions have not met the inverted U-shaped curve's inflection of the energy Kuznets hypothesis yet. According to the relationship between Energy consumption and...
In this paper, we present a novel methodology for computing statistical shape models (SSM's) by leveraging the medial axis model to determine shape variations between objects. Landmark based SSM's (LSSM's) are a popular approach to describing valid shape variation in an object of interest by applying principal component analysis to a set of landmarks on the surface of the object. However, defining...
