From the point of the complexity of knowledge, based on the complex adaptive system theory, combined with computer science and artificial intelligence theories, the author analyzes the complexity of enterprise knowledge management and provides a solution to help enterprises to establish their own knowledge management system.
In this paper a novel view-invariant movement recognition method is presented. A multi-camera setup is used to capture the movement from different observation angles. Identification of the position of each camera with respect to the subject's body is achieved by a procedure based on morphological operations and the proportions of the human body. Binary body masks from frames of all cameras, consistently...
We discuss a new algorithm for traversing possible worlds in games of imperfect information based on the enumerablity of permutations by means of Sims tables. The resulting anytime capabilities of the algorithm are demonstrated by applying it to the card game Schnapsen, popular in Central Europe.
In this paper, a new face detection algorithm based on fractal theory and complexion model is proposed. On the basis of the traditional face detection, the new algorithm estimated the fractal dimension of face area to exclude the non-face area and extract the face area fast and accurately. Furthermore, its calculation is simple and it can realize multi-angle detection in the complex background. As...
Recent work in the field of machine translation (MT) evaluation suggests that sentence level evaluation based on machine learning (ML) can outperform the standard metrics such as BLEU, ROUGE and METEOR. We conducted a comprehensive empirical study on support vector methods for ML-based MT evaluation involving multi-class support vector machines (SVM) and support vector regression (SVR) with different...
Intrusion detection systems (IDS) usually trigger a great number of alarm messages that frequently overwhelm their human operators. Hierarchically clustering technique is able to help IDS operators to get meaningful overviews from the great number of alarms. A dilemma is encountered when the clusters are generated. If the clusters are obtained one by one, they cannot be prevented from overlapping...
Towards building a multimodal affect recognition system, we have built a facial expression recognition system and a audio-lingual affect recognition system. In this paper, we present and discuss the development and evaluation process of the two subsystems, concerning the recognition of emotions from audio-lingual and visual-facial modalities. Many researchers agree that these modalities are complementary...
Particle filtering is known as a robust approach for motion tracking by vision, at the cost of heavy computation in a high dimensional pose space. In this work, we describe a number of heuristics that we demonstrate to jointly improve robustness and real-time for motion capture. 3D human motion capture by monocular vision without markers can be achieved in realtime by registering a 3D articulated...
In this paper we present a subjective quality assessment experiment for 3D-mesh segmentation. For this end, we carefully designed a protocol with respect to several factors namely the rendering conditions, the possible interactions, the rating range, and the number of human subjects. To carry out the subjective experiment, more than 40 human observers have rated a set of 250 segmentation results issued...
Internet and database technology provide the conditions for us to learn human behaviors empirically. Exploring these behaviors is important for us to understand internet users' surfing habits, and to set the stage for better research on social dynamics closer to reality. In this paper, we explore the Internet users' post and reply behaviors et al. in an internet forum, Tianya. Statistical analysis...
This paper proposes a novel low SAR PIFA structure to reduce exposure of the human head to mobile-set antenna radiation. Dual-band PIFA structures operating at 0.9 GHz and 1.8 GHz bands are considered. SAR is decreased by reducing the back-radiation coming from the patch and the ground plane. This SAR reduction is accomplished by inserting a thin metallic layer between the patch and the ground plane...
Most of the coalmine accidents are caused by people's unsafe behavior. Based on the basic theory and research methods of behavioral science, this paper analyzed human factors and rules affecting unsafe behavior. On this basis, it proposed the wholly integrated coalmine safety culture construction methods, with strengthening safety awareness, correcting unsafe behavior and training security practices...
Services are expected to be a promising way for people to use information and computing resources in the emerging ubiquitous network society. In this study, we propose a metaphoric concept called flowable service. It is defined as a logical stream that organizes and provides circumjacent services in such a way that they are perceived by individuals as those naturally embedded in their surrounding...
At present, there are some academic studies on manufacture enterprise virtual operating, but a little academic study on service enterprise virtual operating. Moreover, the study focused on strategic performance appraisal system is almost blank and the empirical study on service enterprises has no discriminative samples. In this thesis, by using value chain analysis as the qualitative investigation...
We study sequential search behavior in a generalized “secretary problem” in which a single object is to be selected from a set of n alternatives. By nature, Alternatives are inspected in a random order, one at a time, and only the rank order of the current alternative relative to the ones that have already been observed can be ascertained. The goal of decision-maker (DM) was maximizing the probability...
Nowadays, the supervision process of industrial installations is more and more complex involving the automation of their control. A malfunction generates an avalanche of alarms. The operator in charge of the supervision must face the incident and executes right actions to recover a normal situation. Generally he is drowned under a great number of alarms. To eliminate the risk of incident, expert systems...
Sensors are being deployed to improve border security generating enormous collections of data and databases. Unfortunately these sensors can respond to a variety of stimuli, sometimes reacting to meaningful events and sometimes triggered by random events which are considered false alarms. The intent of this project is to supplement human intelligence in a sensor network framework that can assist in...
Scientific decision-making as the main symbol of the modern management of enterprises, has been increasingly paid attention by people. Correct decision depends on many factors, we must have a sound decision-making system and comply with scientific decision-making procedures, besides, decision-makers' experience, talent and quality, the use of appropriate decision-making methods are also the crucial...
This paper analyzed the problems of the level of service in a large-sized passenger terminals, pointed out the factors and the relationships among the level of the passenger services of the organization classification, and used the software Legion to conduct a simulation study on free traveling interval, considering the coefficient of self-organization, determined the standards for classification...
The information management software is converting from MIS to ERP in Chinese electric power enterprise at present. MIS has played a great role in promoting the development of the electric power enterprise in China. But while many problems still exist, which block the development of MIS, and these problems will be reflected in the implementation of ERP. The problems are analyzed in this paper, and...
