Array signal processing with robust rejection constraints via second-order cone programming
Vector and array signal processing noise the ellipsoid array robust optimization
2015/8/10
We consider the array signal processing problem of choosing the weight vector to minimize noise power, subject to a unit array gain for the desired wave, and subject to rejection constraints on interf...
The Biological Metaphor of a Second-Order Observer and the Sociological Discourse
sociocy bernetics meaning observer social systems observational report expectation communication
2010/4/8
Purpose: In the tradition of Spencer Brown's (1969) Laws of Form, observation was defined in Luhmann's (1984) social systems theory as the designation of a distinction. In the sociological design, how...

Consider the model X_t=X_{t-l}β + g(U_t)+ ε_t for t ≥ 1. Here g is an unknownfUnction, β is an unknown parameter to be estimated and εt are i.i.d. with mean 0 andvariance σ^2 and U_t are i.i.d. random...
BIFURCATIONS FROM HOMOCLINIC ORBITS FOR SECOND ORDER HAMILTONIAN SYSTEM
Bifurcations homoclinic orbit Hamilton
2007/8/7
An existence theorem of homoclinic orbit is given for second order Hamiltonian system -\"{x}(t) + a(t)x(t) - W_x(t, x(t)) = \lambda x(t) when \lambda=\lambda_1, where \lambda_1 is the first eigenvalue...
STABILITY AND FEEDBACK CONTROL OF A CLASS OF SECOND-ORDER LINEAR SYSTEMS IN BANACH SPACE
Stability feedback control second-order
2007/8/7
In this paper. we are concerned with the stability and control problem for a class of second-order linear systems in Banach space. First. a criterion for the exponential stability of a first-order lin...
We develop the interpolated finite element method to solve second-order hyperbolic equations. The standard linear finite element solution is used to generate a newsolution by quadratic interpolation o...
