Humans can behave adaptively in the different dynamical conditions. In order to realize the task quickly, smoothly or efficiently under the various environments, it is required to adjust the kinematic and dynamic relations among the body and environment according to the task. Recent studies have shown that humans can acquire a neural representation of the relation between motor command and movement, i.e. learn an internal model of the environment dynamics. Then, we can compensate for the external dynamic perturbation in a feedforward manner. Considering the situation of performing the complex tasks, such as using the tools, it is necessary to perceive a simple dynamics from complicated ones. The present paper discusses whether humans can identify one side of dynamics from the mixed environment dynamics.

Recently some scholars build time series forecastingmodel by independent component analysis mechanism. Within component ambiguity , time series approximation and mean difference problems, independent component analysis mechanism has intrinsic limitations for time series forecasting. Solutions for those limitations were purposed in this paper. Under the linear time complexity, those limitations were solved by our proposed methods to ensure the forecasting reward. The empirical data show that our model exactly reveals the flexibility and accuracy in time series forecasting domain.

In this paper, we propose an enhancement partition method that incorporates formal partition, fitting system constraints and hardware orient partition algorithm to solve partitioning issue for embedded multiprocessor FPGA systems. With formal partition, we can rapidly obtain a set of partitioning results that satisfy the system constraints on the number of processors. To fit various system constraints, we find out all partition result sets by fitting system constraints. Finally, hardware orient partition can provide a nearly best partition result for designer to develop multiprocessors syslem-on-a-chip system. Experiment results show that the proposed method can obtain the fitting best partitioning result than other partitioning method using JPEG encoding system example.
In this paper, we present hardware-oriented partitioning approach that can solve the partitioning issues for embedded multiprocessor FPGA systems. In addition, it can gain a better partitioning result, faster executio...

This paper presents some results in the implementation of a local navigation strategy for environment exploration using real robots. As an experimental platform we used the mini-robot Khepera II running in the Tele-workbench. The complete environment is divided into small quadratic patches with some objects placed in it. With on-board infrared sensors and wheel encoder, the robot can successfully explore the unknown environment. Moreover, by calculating the distance of surrounding patches, the implemented algorithm will minimize the distance traveled, and in turn of consumed energy and time. This paper also shows the advantage of using the Teleworkbench for performing experiments using real robots.

Structure alignment could help to find shape similarities between proteins and guide structure classification and fold recognition. Common substructure detection and extraction are especially important, for which could guide the biologist to discover binding site or active site. We represent each segment of alpha-carbon backbone by using dihedral angles and curve moment invariants. Then, local and global structure alignment could be performed by iterative closest point algorithm. Maximum common substructures between a pair of proteins or within a protein could be found. Active sites also could be detected by the proposed algorithm.

2-D projective moment invariants were firstly proposed by Suk and Flusser in [12]. We point out here that there is a useless projective moment invariant which is equivalent to zero in their paper. 3-D projective moment invariants are generated theoretically by investigating the property of signed volume of a tetrahedron. The main part is the selection of permutation invariant cores for multiple integrals to generate independent and nonzero 3-D projective moment invariants. We give the conclusion that projective moment invariants don't exist strictly speaking because of their convergence problem.
