Real-time pose estimation is a challenge in multi-camera vision system due to the demand of rapid response, high accuracy and robustness. Although some works based on multi-camera have been proposed, few works have regarded multi-camera as a fixed integration, which is easier to apply in real robotic application than eye-in-hand/eye-to-hand configuration. This paper proposes a novel Kalman-filter-based...
An adaptive bit-allocation method based on perceptual quality smoothing for wireless video communications is proposed. A visual attention model is build by considering skin, motion and position. Then the perceptual video quality distortion is predicted using the visual attention model and channel state information. Finally the MB target bits are allocated according to the predicted perceptual video...
In electromagnetic machines, ferromagnetic material is one of the key components that affect the magnetic field and thus the output performance significantly. The objective of this paper is to study the influence of ferromagnetic material on magnetic field distribution of tubular electromagnetic linear machines. Generic magnetic field models are obtained for linear machines with various structure...
Ferromagnetic material affects the magnetic field of electromagnetic actuators significantly. This paper studies the effect of back iron on magnetic field of linear motors. Designs of linear motors with single-sided, double-sided, and without back irons are analyzed quantitatively. The magnetic field for different structures is formulated analytically based on magnetic vector potential. The simulation...
Due to the imperfection of transmitter and receiver, Adjacent Channel Interference (ACI) can't be completely avoided when two systems share the adjacent frequency band. This paper investigates the impact of ACI between TD-SCDMA and TD-HSDPA systems operating in macro cell. In stimulation, smart antenna technology is employed and its performance is investigated. Furthermore, the key technologies, Adaptive...
Aim at construct a development platform for HEV powertrain control system to save cost and increase the developing efficiency, this paper analyzes the common characteristics of HEV powertrain; presents the hierarchy of the development platform and possible states of its functional modules; details the system composition method of test platform when using real transmission and simulated transmission...
Gene expression programming (GEP) was improved (IGEP) to overcome the shortcomings that the initial population is generated randomly, there are no standards to measure the gene, and evolution results got before canpsilat be utilized. Quasi-law of nature that excessive multiplication, environmental factor selecting, using pheromones to measure gene, passing on from generation to generation and self-adaptive...
Short-term load forecasting is an important part of the modernized power system administration. Some methods have been applied to short-term load forecasting and obtained a certain achievement. Considering the characteristics of gene expression programming (GEP), it is possible to apply GEP to short-term load forecasting. But there still are some shortcomings of GEP. Such as the initial population...
