On the basis of analyzing the characteristics of voice traffic, this paper constructed a Stochastic Petri Net (SPN) model for data and ON-OFF voice traffic hybrid system. Then, average time delay of the system was analyzed and model-based simulation was conducted with Stochastic Petri Net Package (SPNP) 6.0. Consequently, variation trends of burst time and idle time on average time delay are derived thereby. The methodology of modeling and simulation in this paper can be further used to analyze the performance of multimedia hybrid traffic system.

This system is consisted of four subsystems: GPS communication service system, logistics subsystem, GIS subsystem and integrated monitoring system. The principles of the system and the functions of subsystems have been shown in detail. The paper also analyzed the parsing process of GPS communication service system. The use and research of the system will accelerate the application of GIS in the third party logistics and business. It integrally realizes the located data delivering, the electronic map matching and showing as well as the real-time monitoring function.

According to the traffic sign recognition process converges slowly, easy to fall into local minimum of defects in general BP algorithm, a BP algorithm is discussed in the paper, which is based on the improved conjugate gradient method on the basis of Fletcher-Reeves linear search method. At the beginning, the basic principle of the algorithm is introduced;meanwhile, an in-depth analysis is discussed from the theoretical aspects in the paper. and then the trained BP neural network is applied into the function approximation. Experimental results show that the algorithm has many advantages, such as it has a good effect in solving the rotation and scale invariance with the image, the extracted features with translation, scale and rotation invariance. The fast convergence speed and less iteration of this algorithm can meet the requirements of unmanned vehicle autonomous navigation.

With the advancement of the computer technology and networking, tons of secret information is being transmitted on the Internet. However secret message are at high risk of stealing because these messages seek attention while they are being transmitted. Therefore achieving safe exchange of secret message is an important field of research. Though symmetric key cryptographic methods offer quite high level of security but they require costly hardware to implement these methods. Stenography is a communication method which hide secret message in the cover to protect it from the potential hacker. The safest method to prevent secret message from leaking to first encrypt it and then hide this message in the cover We propose a Secure Intelligence Sharing Scheme to integrate with high hiding capacity and imperceptibility. The proposed scheme uses AES as cryptographic solution and hash type one-way function to store metadata about cover and secret message. The proposed scheme uses JPEG compression technique to control size of the transmitted message. Our experiment is performed using variety of cover data and secret messages.

The alpha-conjunctions basically represent the set of associative, commutative and linear operators for belief functions with the vacuous belief function as neutral element. Besides, they include as particular case the unnormalized Dempster's rule. They are thus particularly interesting from a formal standpoint. However, they suffer from a main limitation: they lack a clear interpretation in general. In this paper, an interpretation for these combination rules is proposed, based on a new framework that allows the integration of meta-knowledge on the various forms of lack of truthfulness of the information sources.

The amniotic membrane exhibits many biological properties that may be helpful in treating ocular surface diseases. In this study, we investigated the effect of topical amniotic membrane extraction on herpes simplex keratitis (HSK) in a rabbit model. The corneas of rabbits were infected with herpes simplex type 1 virus. The rabbits were divided into 2 groups according to topical treatment methods: saline and AM extraction. The corneal lesions and angiogenesis severity were measured and graded at 0,1,3,5,7, and 14 days after treatment. Histologic examination was performed and the expression of interleukin (IL)-2, IL-10 and vascular endothelial growth factor (VEGF) were determined by enzyme-linked immunosorbent assay at 7 or 14 days after treatment. The severity of keratitis treated with AM extraction was less than saline treated eyes after 5 days of treatment (P<0.05). The extent of angiogenesis in the eyes of AM extraction treatment revealed greater reduction than the control ones after 3 days of treatment (P<0.05). The amount of IL-2 and VEGF were decreased after treatment of AM extraction, whereas the amount of IL-10 was increased. The present study showed the extraction from fresh human amniotic membrane dramatically decreased the corneal inflammation and angiogenesis in experimental HSK by modulating the expression of proinflammatory cytokines and VEGF in the infected corneas.

Because of the impellent of the world economic integration, China's enterprises are facing with intense competition which comes from both domestic and abroad. Technological innovation capability becomes the key factor for enterprises to survive and develop. This paper researchs enterprise technological innovation capability which with linguistic information of attribute values and completely unknown information of attribute weights. It determines the weights based on measuring the ambiguity of evaluation protocols, in order to measure and evaluate each enterprise scientifically and systematically. An example verifies this method is a scientific and functional one.

Multiple generations of many durable products serves the markets simultaneously. As technology is growing at a very fast rate, new technology creates the need of higher technology products, and makes firms to introduce new products even when a product is doing well in the market in the order of competition, survival etc. Existence of several generations altogether in the market directly or indirectly affects the sales of the each other by the way of the effects of substitution, upgradation, leapfrogging etc. Products either new or old need to be promoted in the market - initially to create the awareness and later on the grounds of market share and capture. Promotional effort is an important component of marketing mix that determines the success of a product, so must be spent judiciously. In the marketing literature many promotional allocation problems have been discussed under various concerns, but most of them either consider a single product or multiple products each of which is different from other. The effect of existence of several generations of the same product has been ignored while making these allocations. In this paper we formulate a promotional allocation problem for durable technology product using a diffusion substitution model to capture the sales of multiple generations of the product for a segmented market. The model captures the sales of the products along with their substitution effect. The optimization model formulated is a non-linear programming problem. It allocates promotional efforts to the different generations of a product in a planning horizon maximizing sales under budgetary constraint. The model application is illustrated through a numerical example.
