This work considers a nonlinear time-varying system described by a state representation, with input u and state x. A given set of functions v, which is not necessarily the original input u of the system, is the (new) input ...

This work considers a semi-implicit system A, that is, a pair (S, y), where S is an explicit system described by a state representation (x)over dot(t) = f(t, x(t), u(t)), where x(t) is an element of R(n) and u(t) is an ...

The representation of the Brazilian Umbanda religion is discussed from the point of view of the Theory of Social Representations. It is considered that Universal Classification Systems, such as the CDD, do not adequately ...

The Chief Information Officer (CIO) has become increasingly important for companies. However, one can perceive that this professional realizes that his/her competencies are not always enough to tackle a daily professional ...

This paper presents a comparative analysis of the influence of PV bus representation on the convergence characteristics of the Newton-Raphson Current Injection method. The methods used for solving the power flow problem ...

A subspace representation of a poset S = {s(1), ..., S-t} is given by a system (V; V-1, ..., V-t) consisting of a vector space V and its sub-spaces V-i such that V-i subset of V-j if s(i) (sic) S-j. For each real-valued ...

In this article we give necessary and sufficient conditions for a complex number to be a continuous eigenvalue of a minimal Cantor system. Similarly, for minimal Cantor systems of finite rank, we provide necessary and ...

In this paper, I review the main criteria offered for distinguishing the modal and amodal approaches to conceptual format: the type of input to which the representations respond, the relation they bear to perceptual states, ...

In this work we construct the stationary measure of the N species totally asymmetric simple exclusion process in a matrix product formulation. We make the connection between the matrix product formulation and the queueing ...
