On the basis of hypothesis of limited time and multistage order, the order strategy was brought forward for the changing charge, and the multistage stock model with deteriorating lose were constituted for the Single Short Life Products (SSLPs) and Multiple Short Life Products (MSLPs) under different order strategies. In addition, that the combined order mode was better than the other order modes for...
Shock absorber is widely used on vehicle. The purposes of the shock absorber are to dissipate the energy accumulated by the suspension spring displacement, controlling thus the vertical motion between vehicle body and tires. The shock absorber has great influence on both ride and handling performance of vehicles, and a great many previous researches have been done on modeling and simulation of the...
In this paper, we study legacy asset reuse for SOA design. Typically, the cost of reusing legacy assets is much lower than the cost of creating new services from scratch. As an extension of our SOA service modeling, we use top-down approaches to identify business services, and use asset modeling for legacy asset identification to find potential reusable assets for those services. Using service capacity...
This work describes a method of background updating and shadow removal for indoor surveillance. Moving objects can be precisely extracted for various further process procedures such as recognition. Single-Gaussian model which has high computational speed is usually applied to the indoor environment with motionless backgrounds. The pixels of an image are classified as background pixels, moving foreground...
The auto-compensation and harmonic shielding converter transformer, namely the new converter transformer, adopts the prolonged delta wiring in the secondary winding, and there is a tap between the common winding and the prolonged winding, which is connected with the inductive filters. Compared with the traditional converter transformer, the electrical connection in the new converter transformer is...
This paper investigates the collective behavior of a leader-follower system with communication time lags based on nearest neighbors information. The leaders proposed in the swarm can obtain the information from the environment, but the followers can not. Under the common assumptions, we prove that the individuals of the swarm with the local information will aggregate and form a cohesive cluster of...
The research subject of this paper is spherical 5R parallel manipulator, on the basis of analysis of kinematics of the manipulator, the dynamic model of the manipulator was established by virtue of Lagrange method, and via numerical calculating example, the dynamic model of the manipulator was simulated by two software Matlab and ADAMS, by comparing the results obtained by two software, we proved...
Squeal noise in vehicle disc brakes is perceived by consumers as both annoying and warranty cost. Among the methods that have been used to control squeal noise, increasing the system damping has been shown to be very effective. The most commonly used method to increase system damping consists of attaching multi-layer laminates on the back of the brake pads. As brake squeal is a friction induced instability...
This paper analyzes the development tendency of optical networks under multi-service in the future, proposes an original ideology of transport adaptability in reconfigurable all-optical networks, researches on the key techniques of the complex coupling mechanism and dynamic controlling in the process of selecting lightpaths and tuning, such as the architecture of complex adaptability system (CAS)...
IP multimedia subsystem (IMS) realizes the convergence of fixed and mobile networks. In virtue of providing various types of multimedia services among different kinds of access networks, IMS is considered as the core network for future next generation networks. For detecting the requested services quickly and efficiently, it is necessary for IMS to adopt a valid service discovery function. In this...
The rapid adoption of model-driven design (MDD) methodology in SOA-based solution design requires an adaptive tooling environment that can systematically improve designers' productivity. Ideally, the environment should be flexible enough to both handle frequently changing requirements and support new features without intensive coding efforts. In this paper, we provide a coding-free enablement framework...
Compared with the traditional converter transformer, the auto-compensation and harmonic shielding converter transformer, namely, the new converter transformer, has a unique connection. In general, the difficult branches that only contain solitary voltage source sometimes appears in the mathematical modeling for the transformer, but the traditional nodal equations of the transformer are unable to be...
