For hyperspectral remote sensing, the dataset usually contains hundreds of spectral images, which generates a rather large amount of data. To reduce the computational complexity of image analysis, feature extraction is often adapted. This paper presents a new approach for unsupervised feature extraction...

Brightness temperature (Tb), an effectively reflect the real surface temperature index, were quantitatively derived from LANDSAT TM images in Xuzhou city, China. Normalized difference vegetation index (NDVI) spatial model and normalized difference built-up index (NDBI) spatial model were also established...

With the widely use of high resolution remotely sensed image, the methodology of object-oriented classification emerged and became an active research area. Two basic steps of object-oriented classification method is segmentation and classification, and the effect of segmentation will directly affect...

Drone have several advantages over conventional remote sensing techniques. They can acquire high-resolution images quickly and repeatedly. And with a comparatively lower flight altitude i.e. 80~400m, they can obtain good quality images even in cloudy weather. Therefore, they are ideal for acquiring spatial...

Recently, various types of aircraft are flying in the sky. Especially, Unmanned Aircraft Vehicle(UAV) called drones can operate with from aerial photography to unmanned delivery thus, utilization is very high. Drones are classified as Quad, Hexa and Octa copter depending on the number of rotor. However...

The present study illustrates a method for monitoring the urban vegetation around Salalah city, in Dohfar region ,Southern of Oman. Monitoring spatiotemporal changes in urban areas has become increasingly important as the number and proportion of urban residents continues to increase. The synoptic view...

Blooms of harmful algae and phycocyanin represent a significant and expanding threat to human health and aquatic resources throughout the South Korea. Algal blooms can be seen in a variety of phenomenon in nature, ranging from massive accumulations of cells that discolor the water, to dilute, inconspicuous,...

The use of remote sensing classification technology can quickly obtain land use change information. Supervised classification and classification method, In the study area, the change of land use was analyzed. The classification effect depends on the classification scheme. The main purpose of this paper...

The sound source localization method that based on triangular array of wireless sensor networks (WSN) is proposed to locate the sound source and research the error distribution. Using the Time Difference of Arrival (TDOA) algorithm, the proposed sound source localization method can be used to locate...

Today, various types of aircraft are being operated within the city. Especially, most users who buy the drone for entertainment are living in the city. Also demand is increasing for drones it can be used in transport logistics, the limit is needed about illegal activity of these drones. Because, there...

Three-dimensional geological survey was based on the surface geological mapping, which was to solve the major geological problems; it was a comprehensive three-dimensional geological survey, which used modern geological theories, advanced integrated exploration methods and three-dimensional visual information...

This paper discusses interplanetary travel, especially flight to the asteroids, by means of spacecraft which use solar sail instead of an engine and a propellant. The design model of the solar sail spacecraft “Helios” which created in computer-aided design system is described. The mathematical motion...

This paper outlines the optimization of the L1-L2 and L2-L1 missions using electric propulsion. The optimization criterion is the total flight time. The optimal control laws are obtained using the Fedorenko method to estimate the derivatives, the gradient method to optimize the control laws and the Runge-Kutta...

To search the ability of detect metal cracks by differential susceptibility technology, a sawtooth wave driving source system are needed. This driving source is composed of sawtooth wave generator, control unit, summator and amplifier. And solved the problem of other driving source can’t output sawtooth...

In this paper, a non-Newtonian filtration equation with nonlinear boundary condition and a localized source is considered. The existence and blow-up properties of solutions are given under some conditions.

The internal model control design method for stable plants has enjoyed much popularity due to its simple yet effective procedure. In this paper, a robust IMC method is proposed for multivariate singular systems on the basis of Kronecker canonical form, which allows us to analysis and control of a singular...
