This work focuses on common diffusion characteristics in the evolution of national mobile telecommunications markets. The study examines 1G, 2G and 2.5G technologies that coexisted during the period 1991–2003 but exhibited different market penetration rates. In almost all cases studied, it is found that the technology adopters initially increase following a power-law, approximately quadratic or cubic...
In this paper we present an integrated approach to COSMO-SkyMed image analysis and classification exploiting integration of different data of the regions of interest, namely urban forestry areas, wide urban parks. The aim is to provide a methodology for exploiting complex data structures built upon multi resolution grids gathering together with optical and X-SAR images, also historical land exploitation...
Robots learning interactively with a human partner has several open questions, one of which is increasing the efficiency of learning. One approach to this problem in the Reinforcement Learning domain is to use options, temporally extended actions, instead of primitive actions. In this paper, we aim to develop a robot system that can discriminate meaningful options from observations of human use of...
Most approaches for resource management employ simplistic behavioral models of heterogeneous resources. To fully support the rich interaction between resources and business processes in a real business environment, in this paper we introduce a novel approach where resources are modeled in much the same way that we model business processes. Resources are systematically modeled as full-fledged business...
A computational model of multi-scale population densities was developed based on the native population database of Shijiazhuang city. The model comprises four parts: data processing, down-scaling, data format conversion and up-scaling. Down-scaling was completed by apportioning village population to each street block. The vector dataset of block population was converted into 100m×100m grid dataset,...
Flood disaster is one of the major natural disasters, the frequency and destructive power of it ranks one of the top disasters in China. In the flood risk assessment, the distribution of drainage network is a very important assessment factor. This study extract the watershed features of Pearl River Basin and Luan River Basin based on the Digital Elevation Model (DEM) and GIS-supported geospatial data...
To construct an appropriate e-learning system, it is inevitable to evaluate it by testing it with real human learners, but it naturally implies some sacrifices on the part of learners. To minimize the risk, some computational simulative evaluations are desirable. In this paper, we propose a multi-layered multi-agent simulation model for learner's growth through using an e-learning system. As a typical...
A common approach to produce theory to explain the genesis and dynamics of complex networks is to create multi-agent simulations that output networks with similar characteristics to the ones derived from real data. For example, a well know explanation for the power law degree distributions found in blog (and other) networks is the agent-level endogenous mechanism of preferential attachment. However,...
Knowledge based methodology is one of the primary areas of development in engineering problem solving methods for decades. In the meantime, product definition has been moved into model space. Establishment of the STEP (Standard for the Exchange of Product Model Data, ISO 10303) product model standard and it application at leading industries during 90's facilitated development of model based integrated...
Content, evaluation, and applications of competence have been important issues in both academic and practical applications since the 1970s. On the one hand, studies on psychological assessment, human resources management and development have extensively discussed the definition and classification of competence; on the other hand, practical research on the competences of different occupations has attracted...
Determining factors influencing regional innovation capability is helpful for improving regional innovation capability by proper policies. There have been some documents discussing this problem. This paper has a concise review on relevant documents, aiming to clarify the study progress and discuss the future study orientation.
Based on probing R&D into the regression model, this paper empirical analyzes the indigenous R&D investment on economic growth and the neighboring provinces R&D spillovers by using the 30 Chinese provincial panel data from 2000 to 2007. The research proves that whether the whole sample or the regional sample, indigenous R&D is playing an important role in regional economic growth,...
This paper chose five branches of the Agricultural Bank of China as analysis samples, and they are Beijing Branch, Shanghai Branch, Tianjing Branch, Chongqing Branch and Shenzhen Branch, respectively. Firstly, describe the relevance between compensation and incentive of the executive by statistics of data. Secondly, conduct an empirical study to the executive compensation incentive using the mechanism...
Based on the statistical data of 2000-2008 year, covering 31 provinces of panel data, the aim of this paper is to analyze and estimate the relationship between the model of foreign direct investment and the provincial gross domestic product growth rate. We found that foreign direct investment inflows on regional economic growth greatly influence an increase of 1 percentage point per input, it will...
As the prevalent of information technology, the urban management became more and more dependent on information. Subsequently, the wanton propagation of harmful information often cause very serious damage on normal urban order, and is becoming a critical problem faced by modern urban management. In order to gain insight in the harmful information propagation and hold back it effectively, an experiment...
Today, It is very important for large state-owned enterprise to controll information resources talent scaling in human resource strategy. With the demands and characteristics of the enterprise information resource management, the paper establishes and analyzs gray talent train model of information resource management for large state-owned enterprise by gray system theories and models, Which. can forecast...
A noise data processing algorithm based on rigid structure matching for human motion capture (MoCap) is presented in this paper. The noise model is related to parts of human body, but not to trajectories of markers as most used in traditional approaches. Three issues are addressed in this method: rigid structure matching, semantic restriction and noise reduction, and they are three steps of data processing...
A major challenge in modeling with BNs is learning the structure from both discrete and multivariate continuous data. A common approach in such situations is to discretize continuous data before structure learning. However efficient methods to discretize high-dimensional variables are largely lacking. This paper presents a novel method specifically aiming at discretization of high-dimensional, high-correlated...
Distributed multimedia database is the distributed database and multimedia database combination. Distributed mass of large distributed database multimedia database, especially in recent years in education, health, culture, tourism, government administration, commerce and other aspects of a wide range of applications. Based on the study of distributed large-scale multimedia database technology, the...
