Aircraft infrared radiation characteristic is the important basis of penetration performance evaluation. When we use ground-based infrared radiation measurement system test aircraft in the out-field, goals are often in the clouds, the clouds of infrared radiation absorption and scattering makes the transmittance and background luminance change, which aifect measurement accuracy. Radiative transfer...
Recent advances in deep learning have shown exciting promise in filling large holes in natural images with semantically plausible and context aware details, impacting fundamental image manipulation tasks such as object removal. While these learning-based methods are significantly more effective in capturing high-level features than prior techniques, they can only handle very low-resolution inputs...
This paper proposed a self-calibration algorithm for triaxial accelerometer. By analyzing the measurement error factors, the parametric model of accelerometer output was built. According to the principle that the modulus value of gravity vector at a fixed point is constant, the nonlinear state space model of calibration parameters was derived. Further, the iterated extended kalman filter was proposed...
Acceleration and deceleration of the AS/RS machine in automated storage and retrieval systems are considered in this paper instead of uniform speed, and there are curve channels in the warehouse. Based on the above hypothesis, the time function and distance function are studied in this paper. The distribution function of the distance and time is given. On this basis, the expected travel time of the...
The ability of a helicopter to carry externally slung loads makes it very versatile for many civil and military operations. For Helicopter slung-load system in the presence of strong disturbances and complex effects from its load, an Active Disturbance Rejection Control method(ADRC) will be applied to helicopter slung-load system and its parameter tuning based on genetic algorithm(GA) will be proposed...
In this paper, we present a new model reference adaptive control (MRAC) for flight control of fixed-wing unmanned aerial vehicle (UAV) with uncertainties and disturbance. The beginning of new algorithm design is combining direct MRAC with indirect adaptive control, which is called composite MRAC (CMRAC). In the aspect of direct MRAC, we substitute a Luenberger-like reference model for a typical one,...
Due to today's diverse resource constraints and user preferences, video adaptation attracts more and more research interests. A video adaptation framework for scalable video coding(SVC) is proposed in this paper. The content description is acquired off-line, and then a bitstream syntax description is automatic created by a format-specific parser. Finally, video adaptation is implemented based on bitstream...
In the present study, a novel full recycling process for bioethanol production was investigated, where three mathematical models were established to simulate the accumulation of major soluble inhibitory substances, including organic compounds, total ions, volatile fatty acids (VFAs) and colorants. These inhibitory substances in the reused water reached a relative steady state after 3–7 batches of...
