A numerical method proposed to approximate the solution of a class of stochastic age-dependent populations with diffusion. We show that under certain conditions, weaker than Linear growth and Global Lipschits, the Euler scheme applied to Stochastic age-dependent population,converges to the analytic solution, and provide information on the order of approximation. An example is given to illustrate our theory.

Action rules describe possible transitions of objects from one state to another with respect to a distinguished attribute. Early research on action rule discovery usually required the extraction of classification rules before constructing any action rule. Newest algorithms discover action rules directly from a decision system. This paper gives a new approach for generating action rules by incorporating a pruning step through micro-actions. The notion of Micro-actions is introduced. They are nodes in a higher-level knowledge, which are linked with atomic terms showing changes within classification attributes. New influence matrix is presented and used to show the cascading effect of actions modeled as action rules. Moreover, an application of the proposed approach in education is demonstrated.

In this paper, a three-dimensional sketch modeling system is presented. This system is composed of some modules, such as gesture recognition, sketch profile recognition, three-dimensional modeling, and free-form surface modeling, etc. In this study, pattern recognition is adopted to identify different gestures, and a tolerance ring algorithm is adopted to identify primitives, such as rectangles and circles.

In this paper, the nonlinear vibration of the of robotic manipulator with parallelogram hinged mechanism is studied. The relation between the nonlinear vibration of the system and the parameters of the system is obtained. The studies show that the nonlinear resonance of the system are not only related to the structure parameters of the robotic manipulator, but also to the rotational frequency of rotor and the rotating field frequency of stator of the controllable motor, and that under certain conditions, there exist internal resonance, super-harmonic resonance, 1/2-order sub-harmonic resonance, 1/3-order sub-harmonic resonance, combination resonance, and multiple resonance.

Enterprise business intelligence has solved many problems of massive data analysis for business decision-making. With the growing popularity of 3G mobile and its communication devices, it is impossible for businesses or other organizations to implement mobile business intelligence. As current hardware and software facilities for most traditional business intelligence systems cannot be simply applied to mobile appliances, this paper first proposes a lightweight framework for mobile business intelligence under 3G communication standards, then describe in detail its physical and logic architectures both in the server side and mobile terminals, finally provides its implementation solutions by using Pentaho and Android platform tools.

Routing protocols in wireless sensor networks (WSN) have been substantially investigated by researches. Most survey subject have focused on reviewing the different routing schemes that have been proposed for WSN and classifying them based on the network's type and protocol's operation also a fundamental issue in the design of Wireless Sensor Networks is to maximize their lifetimes particularly when they have a limited and non- substitute energy supply. To improve the network lifetime, controlling of power management and energy-efficient communication techniques at all sensors are necessary. In this paper, we propose a new method for the routing issue by using genetic algorithm for WSNs. Our purpose is to maximize the network lifetime by improving efficient routing techniques. Simulation results show that when we use good coefficient of our parameters, the life time of wireless sensor network is increased.

Maintenance disassembly sequence planning is an important part of maintainability design. To tackle disassembly sequence planning problem efficiently, based on the product's basic information and constraint relations between parts, disassembly Petri net reachable graph is presented. The problem of disassembly sequence planning is transformed into that of searching optimal paths in the graph. At the same time an ant colony optimization algorithm is presented to search the optimal solutions. Through examples verify the effectiveness of the method.

The article presents a new arithmetic which uses chain code to recognize fire flame's apex angles in fire detection processing. It applies a concept of custom slip window and defines flame's apex angle acutance index to estimate apex angle's type which could be I type or II type. This method also presents mathematics model and theory deduction and defines relative height parameter as the criterion of apex angles. The recognition method based on chain code is good at inflexion location with a higher speed and better anti-yawp capability rather than traditional method.
