To improve the efficiency of interaction and user experience in desktop-based Virtual Assembly System (VAS), this paper is proposed to establish low-cost but strong immerse virtual assembly experiment system using Kinect and Unity3D engine. For the purpose of employing body motion, gesture and voice to accomplish interaction tasks, establishing assembly model data, hand gesture recognition and changing...
Making the science assessment and prediction of the credit risk of the small and medium-sized enterprises (SME) is a significant part of risk management of commercial bank. This paper firstly integrates Genetic Algorithm (GA) with v-SVR model, creates the credit prediction model, GA-v-SVR, and then builds the SME credit risk indicator system. Using principal component analysis method screens out the...
With the development of Internet, network applications based on awareness information appear increasingly in future Internet, such as context-based routing, content delivery and personalized content recommendation. The full use of awareness information to support those applications makes the fast query of information to be a critical issue. This paper adopts the strategy of "divide-conquer"...
There are many challenges for sentiment classification of user-generated content (UGC) on social media platforms such as micro-blogs. Context dependence, which has been the most challenging problem, is focused on in this paper, and a novel semi-supervised framework is proposed to address the problem. By dividing the feature space of sentiment classification into two parts including the general features...
Using Kalman filter algorithm (KFA) in tracking target in radar networking system (RNS), measure-value of target in networked radar (NR) polar coordinate system has the nonlinear relation with state-value of target in fusion center rectangular coordinate system of RNS. The nonlinear relation does not satisfy linear requirement of KFA application. So this paper virtualizes fusion center rectangular...
According to the nonlinear maneuvering characteristics of flying targets, unscented Kalman filter is used to achieve a two-dimensional trajectory tracking and predicting in the coordinates of camera view field. By calculating the target centroid position in the imaging focal plane, the third-order constant acceleration motion model of two-dimensional is established. Because of the nonlinear characteristics...
Accurate target classification is the keystone of the ship targets recognition in sea battlefields. Aiming at the deficiencies of supervised and unsupervised classified methods, we present a novel scheme called semi-supervised ship target recognition based on affinity propagation (AP). In order to circumvent the problem of choosing initial points, the method introduces affinity propagation clustering...
How to efficiently transfer data among parallel threads is a research hotspot. A common data structure of transferring data among parallel threads is queue. Some writer threads write data into one side of the queue, and reader threads read data from the other side of the queue. Running in parallel environments, some sources, such as shared variables, are critical resources, which require atomic operation...
The manual intervention before the birth dates is very important to reduce the dystocia rate and enhance the survival rate of calves effectively. Information acquisition of the cows' basic sow-activity modes and regulars is one of judgments of manual intervention critical points. Now, the mainstream way has limitations that external sensors are used to obtain information by attaching to the specific...
A mathematical model and a genetic algorithm are proposed to solve a logistics network optimization problem. Combined with the characteristics of urban logistics and e-commerce, the sum of transportation costs, construction costs and maintenance costs are considered in the model to describe the total logistics cost in the network. Since the model is an NP problem, the genetic algorithm is used to...
Agricultural supply chains management is increasing in recent years, among academics as well as practitioners. In this paper, we present a supply chain simulation study for a real case, with the agricultural manufacture and distribution systems of cooperative-centered in concern. We evaluated the key performance indicator of the whole supply chains by building and simulating 3 present models of agricultural...
The wireless sensor network plays a significant role in monitoring the environment near the harbour in order to inform the ships nearby out of dangers and to optimize the utilization of limited sea routes. Based on the historical data collected by the buoys with sensing capacities, a novel data compression algorithm named PCVQ is introduced to lower the budget of wireless communication subject to...
The subpixel imaging technique for image super resolution can get a higher resolution image from two low resolution images which are observed from two linear array CCDs staggered half pixel both along the flight direction and perpendicular direction. In this paper, an adaptive weight interpolation method which considers the Euclidean distance information from two low resolution images for different...
According to the characteristics of the finite energy of the satellite network nodes, in order to solve the problem of which some nodes losing lots of energies because of uneven network flow, this paper proposes a game model of routing algorithm based on 'the mechanism of price', and the model of Bayesian-Nash equilibrium strategy is resolved. The results of the simulation verified illustrates that...
