This paper presents a positioning method through rasterization of MR (Measurement Report) data. MR data consists of numerous wireless information except longitude/latitude data. MR raster positioning method is used to calculate the relevant longitude/latitude information of MR data and group them into corresponding clusters. compared to conventional drive test and call quality test method, MR raster...
There are more inter-RAT (Radio Access Technology) operations between LTE network and GSM/UMTS networks at the early stage of the LTE network construction due to the insufficient LTE signal coverage. The proportion of camping on LTE network impacts customer ratings and revenue of mobile operators. In this paper, a new KPI (Key Performance Indicator) related to LTE camping rate was defined based on...
Face detection is one of the key technology for face information recognition. Currently, face detection is mainly based on the RGB image, which might lead unexpected results when dealing with non-real 2-dimensional face, which printed on clothes and papers. This work proposes a face detection approach based on features of depth image. We used depth camera to obtain the raw depth data, and then mapped...
The virtual driving platform includes hardware and software two parts. Hardware parts refer to the manipulation of institutions such as the steering wheel, throttle and brake pedals, etc. Software parts mainly refer to the virtual traffic environment, the driver can interact with the virtual traffic environment. There are two main factors which determine the fidelity of the virtual driving environment,...
Assembly is one of the most significant stages in manufacture, which leads the importance of assembly knowledge management theoretically and technically. Current assembly design system lacks of intelligent guidance for the reason that assembly knowledge hadn't been used in rightly context. The paper analyzed in detail the current status of assembly knowledge management in manufacturing enterprise,...
The massive distributed, dynamical and evolutionary characteristics of World Wide Web inspire us study it drawing on the Information Foraging Theory which assumes that people prefer yield more useful information per unit cost. Understanding the value of implicit measures is also important to help World Wide Web users search more effectively. Borrowing idea from information foraging theory we propose...
VA (Virtual Assembly) provided a numerical platform for assembly design. However, lacking of intelligent guide is a critical problem in assembly design with VA technology. This paper proposes a novel concept of context-aware in VA, and discusses the connotation and extension of it. Such context should be a small world context that provided intelligent for virtual environment, while an ontology-based...
The design education which is of great significance to the whole society is gradually spreaded and rapidly developed now. According to the problems appearing in the development of design education in China, this paper proposed the innovation of design education system which is based on CO-OP system. It also provides a detailed introduction on the characteristics of the CO-OP system, as well as the...
The application of knowledge visualization in collaborative conceptual design process is a new research field. One of the most important tasks is to find the influence factors which affect this process, as well as problems it facing. This paper presents a detailed research and analysis on these factors, based on a great deal of literature analysis in areas of knowledge visualization, organization...
Usability has been used to measure the core Competitive ability of domestic products. Since usability testing cannot be limited to the tradition manual testing method, a new usability research model of implicit collection of user behavior lib has invoked the interest of the big name corporations. Based on the slideshow dual screen notebook??s auxiliary screen focus functionality development, usability...
Nowadays people begin to apply graphic solution into the industrial design. However, few research works has been carried out, which degrades the effectiveness of graphic solution. Firstly, the paper summarizes the 14 typical diagrams in the fields of commerce and management from the standpoint of general functions of graphic solution, then manages to provide the efficient graphical categories corresponding...
User satisfaction, as an important indicator in usability testing, directly reflects users?? acceptance of the product and to be the most concerned issue in many enterprises and usability departments. Finding out the shortages of satisfaction measurement in current usability testing, this paper took the basic operation processes in the user experience as the staring point, and analyzed the mapping...
Voice search is a kind of promising search approach in the era of mobile internet. Currently, most of voice search services are still manual work, which are expected to be replaced by human-machine voice search based on voice recognition technology. Despite numerous disadvantages of human-human voice search, its interaction approach as natural language communication is obviously superior to human-machine...
There are two problems when conditional T-S fuzzy neural network is used directly in speech recognition system. One is the rule disaster problem, that is, the rule number will increase exponentially with the increase of input dimensions. Another problem is the network reasoning failure resulted from input dimensions too large. The paper presented an improved algorithm of T-S fuzzy neural network....
A computer simulation process of Emotion is viewed as a complete course of events by theory of affective computing flow. Based on this theory, the use of existing multi-agent technology and learning theory will achieve the model of affective computing in the computer, single-agent structure in the system of individual learners used to simulate learner in the learning process emotional excitation process,...
The paper intensively analyzed and researched video playing technology in virtual education environment, which is an application of Pervasive Computing focusing on demand for some important application field with visual technology, proposed a suit of effective settlement making use of decoding, data compressing, texture mapping and the GPU's parallel computing ability which improved the efficiency...
Assembly processes are intervened subjectively by workers severely which has bottlenecked the efficiency of production. The paper analyzes the implementation of assembly based on physical parts and modeling methods in virtual environment, then describes the principle of self-organizing assembly for pervasive environment. Finally, we propose a new mode of data management that separates the part information...
Taking into consideration the deficiency of virtual assembly environment for the assembly sequence, the paper proposed an intelligent decision support system based on neural network and expert system. The system combines the virtual assembly technology with intelligent decision support technology, which makes sure that assembly sequence planning process can not only use the technologist's experience,...
This paper used wavelet theory in noise-robust feature extraction of speech recognition and introduced two kinds of feature extraction methods based on Gauss wavelet filter and combined wavelets filter. The Gauss wavelet filter and combined wavelets filter with critical frequency bands are obtained by studying human auditory characteristic. Wavelet has flexible characteristic in choosing frequency,...
The paper researches the development of the perception in the collaborative environment, combined with the application of Pervasive Computing-Distance Education, and analyzes the perception agent model and the architecture based on MAS virtual learning environment. Then it expounds the role of affection in the learning process, and institutes the rule of apperception, identification and affective...
