In opportunistic networks, forwarding based protocols lead to a large amount of data flow to the highly connected nodes and unfairness of the nodes' traffic load, finally, it makes the highly connected nodes suffer congestion and results in the messages were discarded. To solve this problem, a congestion control algorithm based on Social Awareness is proposed in this paper. When choosing the next...
Ontology learning has become a popular research field recently. However, the typical ontology may not be sufficient to represent uncertainty information. Fuzzy ontology is proposed to solve the uncertainty reasoning problems. But the construction of fuzzy ontology is still a tedious and painstaking task. The cognitive model of fuzzy ontology learning is an automatic model of fuzzy ontology construction...
Autonomous ontology learning is a critical task to reduce the cost of ontology construction for knowledge based systems. This paper provides a cognitive model for ontology learning system, which aims to develop a novel model for knowledge structuring based on the interaction between the process of ontology construction and cognitive psychology. During cognitive process, we simulate human's cognitive...
Accurate position information of the robot is required in many applications. In this work, a novel INS/range-only based UWB/Encode integrated navigation model is proposed. In this model, the positions of range-only based UWB and INS are used for the position estimation of integrated model; the velocities of encode and INS are used for the velocity estimation of integrated model. Then, a filter with...
Software industry as a soul and core of the information industry plays a vital role in the development of the world economy. China's present judicial situation of protection of intellectual property rights to software did not achieve the desired effect and piracy of software is prevalent. New Regulations on Computer Software Protection has narrowed the scope of fair use of original “Regulations” to...
Memory failures are common in clusters, and their destructive effects (e.g., increasing downtime and losing data) make users suffer great loss. Current memory availability strategies mostly require extra expensive hardware. Software approaches based on check pointing technologies intend to reduce the expense, but their high overhead limits the practical usage. In this paper, we present a novel system...
This paper introduces a mapping method for adding a coarse grain (multiple pixels per processor) processing mode to massively parallel cellular processor arrays. The main motivation is to provide the fine grain pixel-parallel processor array with the ability of processing images with higher resolution than the array itself, in a way that is transparent to the programmer. The proposed method accomplishes...
Based on the actual project need, a development platform for brake system is developed by making use of Visual C++ 6.0 development tool. The paper introduces the functions, structure, design process as well as some key technology of the development platform in detail. The result of a living example shows that the platform has friendly user interfaces, powerful functions, which will help users get...
The RFID technology can help the production managers to track and monitor the production process of a single product, which will greatly support the accurate supervisory control of discrete manufacturing systems. Based on our previous work [7], we apply the RFID technology to the Internet-based remote supervisory control of an experimental one-of-a-kind production system. In this paper, we present...
This paper discusses the key technique of finite element modeling for complex precision forging part, which includes geometrical modeling, element type selecting, element meshing and remeshing, material model selecting, friction model definition and contact problem, In addition, the particular application of complex precision forging part in precision forming finite element modeling was shown combined...
Objective To investigate the feasibility of using PWI analysis software in assessment of carbogen breathing BOLD-fMRI in normal prostate. Materials and Methods BOLD-fMRI was performed using a 1.5 Tesla superconducting magnetic scanner (Siemens) equipped with a pelvic phased-array multi-coil in 15 healthy volunteers. BOLD (T2*-weighted EPI sequence, 13 slices, 3mm thickness) were acquired during 5×2minute...
To manage the knowledge of product development period efficiently, a PDM-based product design knowledge management model was proposed. According to the different characters of tacit knowledge and explicit knowledge, a design knowledge classification and related-representation method were introduced. The integration model between PDM and product design knowledge flow which is the key part of the design...
Aspectual component composition platform needs a new kind of language to support the description and verification of the software architecture. Based on the extension of Wright, this paper proposes an aspectual components composition architecture description language-AWright. Since Wright fails to describe system??s non-functional requirements and lacks corresponding elements for describing the coupling...
In large software system, components depend on each other and should not be evaluated individually. This paper proposes a new process for multiple COTS selection based on extension of a proven system decomposition technique FCD. During the process of decomposition, local requirements are allocated into functional modules as local evaluation criteria for COTS candidates while crosscutting requirements...
In current COTS software components evaluation methods, the resulting scores only represent relative ranking of the alternatives and the differences in their value does not give any indication of their relative superiority. Based on gap analysis theory, a new evaluation approach is proposed in this paper. The functional and non-functional gap between COTS components and system requirements are identified...
Instant messaging (IM) is a popular Internet application around the world. In China, the competition in the IM market is very intense and there are over ten IM products available. However, many of these products are not well accepted by Internet users and they only have small market shares. These companies are eager to know what factors determine user's acceptance of IM. In this paper, we examine...
With the rapid development of embedded system, it takes an important role in the industrial Ethernet control domain. Joining a project, this paper presents a cost-effective and high performance scheme of Ethernet accessing in data collection and processing system which based on ADSP-BF533. Implementation of hardware and software architecture is provided, and then the method for programming the driver...
In many multimedia SOC (System on Chip), application software and data are stored either in on-chip memory or in Cache for efficient execution. Therefore, large amounts of on-chip memory increase the area and power dissipation of the whole chip. In order to reduce memory size and its power dissipation, parts of programs and data are stored in off-chip memory, and are loaded into on-chip memory while...
