This paper presents an augmented state observer design for linear time-varying continuous-time systems with unknown inputs. An equivalent augmented state system, which is free of unknown inputs, is derived for the purpose of simultaneous input and state estimation (SISE). It is shown that, through the...

The localization is an important technology for the sensor network. In this paper, we improved the large error of the Bonding-box algorithm in the case of the two anchor nodes and the disadvantages of the indistinguishable localization of coordinates. The algorithm is combined with the ranging technology...

Aiming to solve the track refined tracking problem of the formation targets with the multi-sensor detections, based on the relative invariant of the actual positions of the formation targets in each detection period, a new algorithm named multi-sensor formation targets template matching tracking algorithm...

An dynamic filtering based obstacle detection algorithm is proposed for the navigation and control of Autonomous Land Vehicle (ALV). The algorithm detects the obstacles using sequential sonar data from dual sonar sensors. The sonar model is described at first. Then the obstacles' features, depicted as...

In this paper, we propose measurement system of the six degree of motion errors which is based on distance measurement by the laser interferometer. The system has six parallel laser beams and six corner cube mirrors on the linear stage, which reflect the corresponding laser beams. The error of axial...

A method about the fractal characterization of nonstationary time series, which is based on measure by dividing the sequence into many segments and not sensitive to embedding dimension, is proposed in this letter. There are several differences in our method compare with above methods. To analyze several...

We introduce a simpler approach for obtaining of usable processing algorithms of fast fluctuating Gaussian pulses with arbitrary modulation function in conditions of parametric prior uncertainty. We carry out the synthesis and analysis of the quasi-optimal measurer of a low-frequency random pulse signal...

Tobacco distribution Reducing energy consumption in tobacco logistics distribution process is one of the important measurements for energy saving and emission reduction of tobacco industry. Tobacco distribution vehicle routing optimization problem is essentially a typical NP problem. As a novel swarm...

With the ever-increasing design scales of electronic products and weapons, it is essential to make a design for testability (DFT) in the process of product research and development. To confirm the correctness of testability design and analysis, it is necessary to perform testability verification for...

A gearbox fault detection and diagnosis test table of wheeled armored vehicles is designed and established. Typical faults and vibration experiments can be preset. Aiming to the d that traditional spectral kurtosis algorithm cannot be applied to gearbox fault signal feature extraction under strong noise...

Phase image processing algorithm with use of computational capabilities of graphics processing units (GPUs) in case of measurements of three-dimensional geometry by method of phase triangulation is offered. It is shown that the implementation of phase images decryption GPU algorithm operates more than...

Commercial vehicles information service platform has not been constructed in transportation industry yet. It researched about data interaction and information sharing between administrative department, transport enterprises, maintenance enterprises and multiple-function detecting test station of commercial...

In this paper, based on penalized least squares, the penalized weighted sum of squares is set up, we deduce the calculation method of a positively definite regularity matrix and obtain the corresponding results in least squares collocation model. According to the foundational properties of the random...

With the highly development of China's economy and the popularization of higher education, the employment situation has never been so serious for college graduates due to various factors. Therefore, improving the quality of cultivating talents and fostering high-quality talents has turned to be the core...

This study intends to use the National Health Insurance Research Database to collect "Cohort Dataset". NHI enrollees from 2013 to 2014 before random sampling for analysis in accordance with code 430 to 437 of the International Classification of Diseases, the 9th Revision. By constructing hierarchical...
