Abstract. Seismic techniques provide the highestresolution measurements of the structure of the crust and have been conducted on a worldwide basis. We summarize the structure of the continental crust based on the results of seismic refraction profiles and infer crustal composition as a function of depth by comparing these results with highpressure laboratory measurementsof seismic velocity for a wide range of racks that are commonly found in the crust.. The thickness and velocity structure of the crust are well correlated with tectonic province, with extended crust showing an average thickness of 30.5 km and orogens an average of 46.3 km. Shields and platforms have an average crustal thickness nearly equal to the global average. We have coiTected for the nonuniform geographical distribution of seismic refraction profiles by estimating the global area of each major crustal type. The weighted average crustal thickness based on these values is 41.1 km. This value is 10 % to 20 % greater than previous estimates which underrepresented shields, platforms, and orogens. The average compressional wave velocity of the crust is 6.45 kmls, and the average velocity of the uppermost mantle (Pn velocity) is 8.09 kmls. We summarize the velocity structure of the crust at 5km depth intervals, both in the form of histograms and as an average velocitydepth curve, and compare these

this paper, we investigate burst responses with rectangular waveform observed in an electrical circuit described by the MBVP equation.The study ofrectangular waves is motivated by an investigation of a pattern#S==x6.## neuron.It is known that most rhythmic behaviors such as respiration, locomotion and feeding are under the control of neuronalnetworks in central pattern generators.The snail'sfeeding rhythm [5], or rhythmic ingestive movements of the radula and mouth, is relatively simple and then the feeding neuron enables a better understanding of the neural basis of rhythm generation.Self##x.46LSj.# of the neuron show an interesting property such that the period of the wave monotonously depends on the variation of a physical parameter.This phenomenon isconsidered as an essence of making feeding rhythms.The purpose of this study is to clarify mechanisms of various
Generating Steering Behaviors for Virtual Humanoids using BVP Control

Abstract One of the main challenges on animating embodied autonomous characters in realtime applications is the ability to generate believable behaviors, more precisely, actors capable of moving in a natural and improvisational manner.

based upon boundary value problems (BVP) to control steering behaviors of characters. We use a field potential formalism that allows synthetic actors to move negotiating space, avoiding collisions, and attaining goals, while producing very individual paths. The individuality of each character can be set

Abstract: A direct formulation of the boundary element method (BEM) for the Laplace equation leads to an integral relationship that represents a superposition of the singlelayer and the doublelayer potential.

This work develops an εuniform finite element method for singularly perturbed boundary value problems. A surprising and remarkable observation is illustrated: By moving one node arbitrarily in between its adjacent nodes, the new finite element solution always intersect with original one at fixed point. Using this fact, an effective εuniform approximation out of boundary is proposed by adding one point only in the grid that contains boundary layer. The thickness of boundary layer is not necessary to be known from priori estimation. Numerical results are carried out and compared to Shishkin mesh for demonstration purpose.

We apply Support Vector Machines (SVMs) to identify English base phrases (chunks). SVMs are known to achieve high generalization performance even with input data of high dimensional feature spaces. Furthermore, by the Kernel principle, SVMs can carry out training with smaller computational overhead independent of their dimensionality. We apply weighted voting of 8 SVMsbased systems trained with distinct chunk representations. Experimental results show that our approach achieves higher accuracy than previous approaches.
