This thesis investigates the synchronization of digitalized DSSS receiver in high-dynamic and low SNR environment, presents the methods of fast acquisition and precise tracking for PN code and carrier.
The aircraft have high dynamics in aeronautic and astronautic fields, and there are many random errors in the high dynamic GPS positioning data. With the measurement series for GPS and establishing a kinematic model to describe the motion of the user, the errors will be decreased and the positioning precision will be increased when applying the kalman filtering to GPS positioning computation model.
A Novel Multiple Access Protocol for Highly Dynamic Self-Organizing Networks
Simulation results show that compared with other cluster protocols,the proposed protocol effectively ensures the stability of cluster architecture in highly dynamic mobile environment because the willingness factor and cluster maintenance scheme take into account the mobility of every node and the relative mobility feature between nodes.
2. The sculling error in the velocity calculation is described and the sculling optimal compensation algorithms are derived in the sculling base motion environment. For testing the sculling correction algorithms' performance, several simulations are practiced and the simulation results show that the sculling compensation term in the velocity integration algorithms can not be neglected for the high accuracy SINS in highly dynamic environments.
It is shown that the suggested adaptive system of estimating the torsion angle of the shaft ensures a high dynamic accuracy in the stationary and nonstationary modes of operation of the engine.
An Effective Tone Mapping Operator for High Dynamic Range Images
Simulation of natural daylight illumination determined by a high dynamic range image
The use of high dynamic range images as a source of the natural daylight illumination and a background for virtual scenes containing objects with complex optic properties (fabrics, automobile multilayer paints, etc.) is considered.
An analysis of the correctness of the available high dynamic range images is performed, and their drawbacks are discussed.
Individual mitochondria which form the chondriom of eucaryotic cells are highly dynamic systems capable of fusion and fragmentation.
The available data suggest that lesion recognition by DNA glycosylases is a highly dynamic process that is accompanied by multiple conformational changes in the enzyme and DNA substrate.
The hypothesis is suggested that, in the area of Chilean fjords, the successful introduction to rivers and artificial rearing in cages in brackish water resulted in the formation of a peculiar and highly dynamic population system.
This response can be regarded as highly dynamic that not only determines the physical elastic properties of the vessel wall but also its cellular components via growth factors, cytokines, and metalloproteinases.
The greatest challenge for proteomics is the inherently complex nature of cellular proteomes as they are highly dynamic entities.
