Based on a simple infinite dimensional electromagnetic system consisting of a linear lossless transmission line in combination with a nonlinear boundary condition,the local map of backward voltage wave is established by using the traveling wave theory.

The analytical formula of the Jacobian matrix of local map is obtained and proven by geometrical method according to the continuity and transversality condition.

In this paper the authors analyze the way of designing the Hamilton net and non Hamilton net protection ring as well as its improvement scheme—a protection ring based on Local map.

This algorithm based on the basic of image registration, for the redundancy high-resolution component between the low-resolution frames, the high frequency was distilled through the local MAP estimation. By compensating the high-frequency component, the high-resolution images are recovered. This algorithm solved the problems in traditional methods that the translation and rotation should not be too large.

A hierarchical structured feature matching method is proposed, which is utilized in the matching between the global map and the local map, the method is implemented and verified by the experiment result.

ln this paper, effOrts are focused on the researches of some pivotal technologies of the vision-based navigation of outdoor mobile robots such as: road scene understanding, stereo-vision forobstacle detection, and tl1e generation and fusion of local map.

We prove that the scaling properly ties of the local map carry to the coupled systems, with an additional scaling factor of length scales implied by the synchronous updating of these dynamical systems.

We consider the (traveling-wave-like) fronts which propagate with rational velocityp/q in a simple coupled map lattice for which the local map has two stable fixed points.

The reduction scheme replaces the local map by an approximation in terms of a step function based on a straightforward analysis of the local dynamics.

A case study illustrates the generation of alternative land cover maps for a Landsat Thematic Mapper (TM) subscene, and the subsequent construction of local map quality indices.

A?local map is maintained using available sensor data, and adjacent objects are combined as they are observed.

The purpose of this paper is to provide a theoretical model of tidat strain ror practical application. This model consists of two parts, i.e., body tidal strain as a consequence of the attraction by the sun and the moon and loading tidal strain caused by the action of ocean tides. For the former, in order to save computation time, we start from Wahr's tidal model, but make a few simplications, so that the components of strain tensor can be obtained from the tide-generating potential directly. As to the latter,...

For the former, in order to save computation time, we start from Wahr's tidal model, but make a few simplications, so that the components of strain tensor can be obtained from the tide-generating potential directly. As to the latter, the effects of four main ocean tides, i.e., M2, S2, O1, K1, are taken into consideration. The eotidal maps used are Schwiderski's global maps associated with the local maps of China Sea.

This paper mainly deals with the single grazing impact phenomenon of the rub-impactrotor system by using the method of Poincare map analysis. As we know, rub-impacts of rotorsystems are always suddenly occurring and hardly predictable. The recent research indicates thatthe rub-impacts are intimately related to a phenomenon called grazing impact, which is in facta critical rub-impact when the rotor touches the stator with very low radial velocity that nearlyequals 0. of cause, it is quit difficult to set up a theoretical system for the general case of rubimpact, which includes the single impact, the multiple impacts and the wholly whirling.impact.But it is somehow an easily thing to investigate the motions of the rotor system with the singleimpact since the rotor touches the stator only once a period. Now, a certain trajectory (grazingorbit) is chosen and a local map is constructed near the trajectory. Then the local dynamicalbehavior can be obtained by study of the map. Because of the discontinuity of stickness in the rub-impact rotor system, the flow in the phasespace is not smooth and even discontinuous. Those common measures for the smooth dynamicalsystems, such as the method of central manifold and linearizing of the system ill the neighborhoodof the fixed point, become invalid. However, enlightened by the significant work of S. W. Shawand A. B. Nordmark, the method concerned in the non-smooth dynamic system of single degreeof freedom is successfully applied to the rub-impact rotor of two degrees of freedom in this paper.And some special dealments including the theory of limits for sequences and singular analysis areused to determine the stability of the fixed point of the Poincare map, and also the attracted regionis found for the fixed point.A further study gives the interesting result of the grazing bifurcation for the non-smoothdynamical system. It is turned out that the appearance of grazing impact causes the uncertaintyto the motion of the rotor system and changes its stability. It may be the stable periodic motionbefore the grazing impact, but if the grazing impact occurs, the stability of the motion can beeither stable or unstable. Soon after that, chaos will follow it. The essence of this phenomenonis just because of the non-smooth characteristic of the system. That is, the grabing bifurcationcauses the square root singularity in the impact map whiCh makes the Jacobian of the map nosense as rotor touches the stator with zero radial velocity. When the motion of the rotor systemis near the grazing impact, it experiences stable periodic motions, grazing bifurcation to irregularrub-impact motions with the variation of the system parameters.

Based on the Volterra expansion of nonlinear dynamical system functions and the deterministic and nonlinear characterization of the chaotic signals,an adaptive higher\|order nonlinear Fourier infrared(HONFIR)filter is proposed to make prediction of chaotic time series.The time domain orthogonal algorithm is taken to update filter's coefficients.A higher\|order nonlinear adaptive filtering scheme is suggested in order to track current chaotic trajectory by using preceding predictive error for adjustign filter parameters rather than approximating global or local map of chaotic series.Experimental results show that:(1)this adaptive HONFIR filter can be successfully used to predict hyperchaotic time series;(2)the prediction capacities of the HONFIR filter is related to its nonlinear function,but not determined by the HONFIR filter's degree of nonlinearity;(3)the adaptive prediction performance of the HONFIR filter is not confined by the Takens embedding dimension;(4)the proposed HONFIR filter can have some anti\|noise ability.
