Hand gesture plays an important role in nonverbal communication and natural human-computer interaction. However, the complex hand gesture structure and various environment factors lead to low recognition rate. For instance, hand gesture depends on individuals, and different individuals' hands are with different sizes and postures, in addition, unconstrained environmental illumination also influences...
The complicated diagnosis methods on those differentiation of TCM was directed by TCM theory which contains the inherent regularity and abundant connotation on TCM diagnosis. The knowledge model is that abstracts the TCM knowledge formalized and structured. In order to establish the knowledge models of TCM which is distinct levels, exact concepts, rational construction and normative statements, through...
This paper proposed a novel dispatching model to schedule the spinning reserve plan which is minimum required for coping with wind power uncertainty. The proposed model is robust to accommodate multiply scenarios of wind power, including normal and extreme scenarios. Different from other robust model, this model does not contain any intractable function in objective function or constrains, such as...
Prosody is the property of natural language. Sign language is a kind of language for the hearing impaired, so the prosody is definitely imbedded in sign language. This makes the prosodic sign language synthesis to be necessary. However, the current research on sign language prosody is mainly concerned with sign language linguistics. This paper studies the prosody of Chinese Sign Language (CSL) from...
The TES gene was frequently lost in breast cancer, which could inhibit tumor invasion and the formation of distant metastasis. However, the underlying mechanisms remain unknown yet. In the present study, we aimed to investigate how TES was silenced and its roles in EMT—the key step for tumor metastasis. Real-time polymerase chain reaction (PCR) and Western blot were used to detect the mRNA and protein...
Due to the features of environment of subway space, humans are lack of sense of position and direction, which will easily cause problems of spatial cognition disorder and low way-finding efficiency. This thesis takes typical subway space in Tianjin as main researching object. Based on public survey, it makes researches on subway users' normal behavior modes from anthropogenic factor, spatial factor...
In concatenating-based sign language synthesis, sign language words are usually captured in context free environment to construct database, and then the words corresponding with the input nature text are selected from the database and concatenated into sentences for synthesis. One problem here is that sign language words would exhibit diversified expression while embedded in different context. Including...
In wireless network, traditional TCP protocol has not the better solution to the problem of data loss. Then, we develop the new point to point TCP cross-layer design method (NTCP) based on RTS/CTS. NTCP divided traditional TCP protocol into transmission rate control and data integrity control, avoiding using the method of forwarding node information, use the most largely the wireless resource o The...
This paper develops a portable MANET terminal. It provides a self-healing, robust, mobile network that supports voice, video communication, and other data applications. The terminal includes a system board based on PXA270 and a video compression board based on BF537, using 802.11 b/g external network card as wireless transmission equipment. This paper proposes a route protocol special for small scale...
Unit commitment is an important and difficulty aspect of optimal operation of power systems. Because it belongs to be mixed variables programming that is difficult to find the optimal solution in mathematics. This paper presents a new method combining of neighbor search and interior-point method (LS-IP) to solve UC NP-hard problem. The structure of neighborhood is defined and a new way to adjust neighborhood...
Short-term load forecasting plays an increasingly important role in the electric network dispatching organization. Here, the default rules mining algorithm is applied to power system short-term load forecasting. First, the conditional attributes such as temperature and humidity that affect load characteristics are discretized by rough set discretization algorithm based on Gini index, and the consideration...
Modularity is the key way of innovation and mass customization, and it is the process of decomposition and integration of whole object in logic. The situation of modularity is in a middle section of the complexity continuum. While study modular innovation in service product and process, we found there are many fields employed modularity, such as economics, psychology, design, and production, etc....
Based on rough set, this paper use discernibility matrix to reduce the condition attributes. The reduced samples are laid by weighted mean roughness to avoid blindness and redundancy. By this method, model space can be compressed greatly and weighted mean roughness is easy to calculate. Weighted mean roughness is used to separate attributes' priority in every lay, which make the diagnosis system had...
A new data-mining method for assessment of the ability of bidding units is proposed in this paper. The algorithm of reducing attribute value is introduced to get minimum rules. An example which considers the various factors is illustrated the procedure of finding association among many factors and then obtained the rules to assess bidding units ability. The rules are very useful in supporting the...
Making use of the resources on the WWW fully and effectively has become important for more and more people. Based on this, we designed and implemented a prototype of a personalized intelligent navigation system, PINS. It assists users in finding and obtaining the information they are most interested in more efficiently. In order to gain portability, scalability, interoperability, reliability and good...
Interferon (IFN) upregulates tumor antigenic expression and enhances tumor uptake of radiolabeled tumor-specific monoclonal antibody (MAb). IFN also increases tumor blood flow. The relationship between these phenomena was investigated. Human melanoma tumors grown in nude mice were used as the experimental tumor model, and 99m Tc-MEM136 as an MAb. Tumor blood flow was monitored...
