In this paper, a new viewpoint, "individuality" and "sociality", is introduced for analyzing the multi-agent system's behavior. A hypothesis is set up that the both behavioral characters emerge to generate different actions from the other agent to increase each agent's bene t. "Individuality" is de ned as the di erence of actions between agents based on the di erence of its internal information...

This paper studies the in uence of knowledge difference on the performance of a search agent | { a controllable camera that can pan, tilt and zoom. The task of the agent is to search for a 3D target within a 3D environment. The goal is to maximize the probability of detecting the target within a given period of time. The search agent does this by autonomously controlling its state parameters to...

We measure varietal di erences in general, and di erences with respect to standard languages in particular ( dialectality , in Herrgen/Schmidt's sense) in order to systematize observations about dialect di erences, to make sense of exceptions, and to enable measurements based on randomly selected material, thus obviating issues of potential bias. Finally, measurements allow the characterization...

This paper considers the ®xed-structure, discrete-time mixed H2=H1 controller synthesis problem in the delta operator (di€ erence operator) framework. The di€ erential operator and shift operator versions of the problem are reviewed for comparison, and necessary conditions are derived for all three formulations. A quasi-Newton/continuation algorithm is then used to obtain approximate solutions ...

We examine the stability properties of a class of LTV di"erence equations on an in&nite-dimensional state space that arise in backstepping designs for parabolic PDEs. The nominal system matrix of the di"erence equation has a special structure: all of its powers have entries that are −1, 0, or 1, and all of the eigenvalues of the matrix are on the unit circle. The di"erence equation is driven by...

In this paper, we are concerned with oscillation of the nonlinear di¤erence equation (cn [ (dn xn)] ) + qnf(xg(n)) = 0; n n0; where > 0 is the quotient of odd positive integers, cn, dn and qn are positive sequences of real numbers, g(n) is a sequence of nonnegative integers and f 2 C(R;R) such that uf(u) > 0 for u 6= 0:We establish some new su¢ cient conditions for oscillation by employing the ...

This paper describes a new symmetry-based approach to solving a given ordinary di¬erence equation. By studying the local structure of the set of solutions, we derive a systematic method for determining one-parameter Lie groups of symmetries in closed form. Such groups can be used to achieve successive reductions of order. If there are enough symmetries, the di¬erence equation can be completely ...

Dynamic load balancing on hypercube multiprocessors is considered with emphasis on quantized loads. Quantized loads are divisible only in a xed size. First, we show that a direct application of the well-known Dimension Exchange Method(DEM) to quantized loads may result in di erence in assigned loads to processors as large as logN units after balancing for a hypercube of size N . Then we propose...

We analyze wireless communication systems employing multiple-transmit multiplereceive antennas in this thesis. Space-time codes have been proposed in the literature as an e cient means of coding over multiple transmit antennas. In particular, the rank and the determinant of code di erence matrices have been shown to be important in the design of space time codes in quasi-static fading channels....

This paper presents a study of the behavior of several di erence approximations for the incompressible Navier-Stokes equations as a function of the computational mesh resolution. In particular, the under-resolved case is considered. The methods considered include a Godunov projection method, a primitive variable ENO method, an upwind vorticity stream-function method, centered di erence methods ...
