A new approach for differentiability of interval-valued functions as first step toward fuzzy differentiability
(2015-09-29)
This manuscript presents a new approach to work with concepts of interval calculus, such as interval differentiability. Moreover, we present the relationship that there exists between our approach to interval differentiability ...
On the Relationship Between Differential Item Functioning and Item Difficulty: An Issue of Methods? Item Response Theory Approach to Differential Item Functioning
(SAGE PUBLICATIONS INC, 2012)
The relationship between differential item functioning (DIF) and item difficulty on the SAT is such that more difficult items tended to exhibit DIF in favor of the focal group (usually minority groups). These results were ...
A new approach to linear interval differential equations as a first step toward solving fuzzy differential
(2018-09-15)
This study uses a concept of interval differentiability, which was recently introduced, to formulate interval initial value problems involving linear interval differential equations. Differently from the approaches that ...
Solving fuzzy differential equations via differential inclusions
(Atlantis Press, 2015-01-01)
In this paper we present a procedure to obtaining the solution of a fuzzy differential equation via differential inclusions. This procedure is an alternative approach, based on optimal control tools, to obtaining a description ...

On state representations of time-varying nonlinear systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
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 ...
