Support vector machine (SVM) now attracts increasing attention in gas classification due to its high performance towards small samples and nonlinearity problems of the dataset. Previously, the probable mismatch between the dataset and the training parameters determined by trial and error or grid search may hinder the exploration of the best result. In this paper, we propose a novel approach to estimate...
The space information transmission network(SITN) is a large scale, strong time-variant, and complex network supporting with the interconnection of heterogeneous networks. As the core of the system, reasonable configuration of backbone network is the chief factor to determine the feasibility of system development and capacity of networked transmission. Based on the architecture of SITN according to...
Texture is an important feature in RS image classification of land-use, and its precision mainly depends on the scale parameters, which are strongly correlated with the geometry characteristics of the classified objects. However, there is no a recognized reliable method for texture scale extraction. So this paper proposes an new approach to indirectly extract them with the assistance of domain GIS...
UHF sensor plays a very important role in UHF method. In order to overcome the shortcomings of the external GIS partial discharge (PD) detection sensor, a small quasi TEM horn antenna sensor is designed in this study. Compared with the traditional TEM horn antenna, it uses the dielectric-loading, three-dimensional microstrip and back cavity structure considering the bandwidth and gain performance,...
The atmospheric sounding spectrometer is a kind of Fourier transform spectrometers, which are sensitive to many kinds of micro-vibration. This focus is mainly on those connected to mechanical vibrations, assessing the relationships between the micro-vibration and the spectral properties of atmospheric sounding spectrometer. A kind of method that atmospheric composition detection method, which utilizes...
The Giant Magneto-Impedance (GMI) sensors based on GMI effect of sensitive material is one of the hot spots in the field of magnetic sensors. This kind of sensors has a very superior performance, in terms of sensitivity, response speed, stability, volume, power consumption and so on, GMI sensors has obvious advantages, and has a wide range of research value and development prospects. Through summarizing...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
During rapid urbanization process, one of the most representative environmental problem in the world is the urban heat island (UHI) effect. In contrast to those warming effect, urban water bodies which are known as ‘urban cool islands’ (UCI), have been considered as an effective measure in alleviating UHI effects and improving urban thermal environment. Therefore, it is of great significance to study...
Progress robot development very varied almost all fields seize the attention of the world's scientists and researchers. For some cases, robots are generally used to help humans in relieving job. The robot can replace human mobilization for move so that the efficiency of wasted time will be less. Many things need to be note what kind of robot control reliable to replace human work in mobilization....
The haptic interface plays important role in remote robot applications since it helps people to feel the real condition to make the control accurate. However, the uncertain time delay in the remote communication introduces issues for critical real time applications, which should be compensated to obtain accurate control. In this paper, the model is proposed first and its stability is studied, second...
The micro-Doppler induced by micro-motion in radar target represents an important characteristic made available for target recognition, which is usually manifest a sinusoid in the time-frequency (T-F) domain. Inverse Radon transform has been validated as an effective sinusoid detection method. Considered on the condition that multiple sinusoids existed in the T-F plane especially one is weaker relatively,...
The low frequency ultra-wideband bistatic synthetic aperture radar (LF UWB BSAR) system has the well ability of penetrating the foliage, high-resolution imaging and providing the increased information, thus it is able to detect the vehicle-size targets concealed in the forest. Initial experiment of the LF UWB BSAR system has been carried out in late 2015. In this experiment, both monostatic and bistatic...
For ultrasonic echo signals, to analyze the maximum peak ± 1 period error in the cross-correlation measurement of the finite sequence, to propose a method to increase the ratio of the maximum peak and the adjacent peak, and to avoid the periodic deviations in the maximum cross-correlation peaks. This method uses a dual-frequency excitation signal and a selective envelope with a triangular fast decay...
Inverse Synthetic Aperture Radar has been proved to be a powerful tool in imaging moving targets in military and civilian applications. The target's movement with respect to the radar sensor provides the angular diversity required for range-Doppler ISAR imagery and image blur due to its motion error. For real targets such as plane, ship and tank have complicated motion components which are unknown...
Due to its physical design, moving coil loudspeakers exhibit distortion at high excursion signals. The identification of the nonlinear parameters gives the physical cause of the distortion, which is important for diagnostics and allows for a more realistic modeling. This work presents a measurement system for nonlinear parameters of miniature moving coil loudspeakers by using voltage, current and...
In this study, with the help of the front camera of a smart phone, decreasing the possibility of accident by analysing the state of sleep from the movements of the driver and the car is aimed and a program which informs the driver's relatives via sending them a short message service in case of an accident is worked on. Detection of the speed of the car by using global positioning system and accelerator...
