Testing the media equation with children

Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2005
Designers of children's technology are often more interested in user motivation than those who design systems for adults. Since children's technology often has aims such as education or practice, keeping the user engaged and interested is an important objective.

Numerical test of the Liouville equation

Physical Review A, 1986
Dynamic ensemble theory is tested numerically for an ensemble of 1000 classical one-dimensional oscillators obeying canonical ``Nos\'e-Hoover'' dynamics. This dynamics couples each oscillator to a canonical heat bath characterized by a temperature and a relaxation time.

On the moore test for coupled equations

Computing, 1997
The author describes an improved Moore test for the existence of a solution of a coupled system \(f(x,y)=0\), \(g(x,y)=0\). Based on this result convergence of an iterative algorithm for solving coupled systems is proved.

Complexity of the EQUATE testing strategy

Journal of Systems and Software, 1988
Abstract Most testing methods do not fare well with software whose modules contain data and operations at widely varying levels of abstraction. With the evolution of new design techniques and new languages that encourage the use of more abstract data types, it is becoming increasingly important that testing methods begin to deal with abstraction in a

The Reliability of Linearly Equated Tests

Psychometrika, 1994
An asymptotic expression for the reliability of a linearly equated test is developed using normal theory. The reliability is expressed as the product of two terms, the reliability of the test before equating, and an adjustment term. This adjustment term is a function of the sample sizes used to estimate the linear equating transformation.

WALD TESTS AND SYSTEMS OF STOCHASTIC EQUATIONS

International Economic Review, 1987
We have presented several results that enable the applications of Wald tests to systems of stochastic equations where the hypotheses of interest also relate to the parameters in the variance matrix. The chief advantages of our formulation are that the methods can be implemented rather easily since it is only necessary to optimize the usual concentrated

The Painleve test for the drift-wave equation

Plasma Physics and Controlled Fusion, 1991
When making a formal Laurent expansion for the solution of the one-dimensional drift-wave equation it is found that a compatibility condition is not satisfied. Thus the drift-wave equation does not pass the Painleve test.

Stability of Some Test Equations with Delay

SIAM Journal on Mathematical Analysis, 1994
The authors propose some techniques to obtain stability conditions for certain differential equations with delay. These techniques are applied to three concrete test situations. In the first and second cases, they consider equations without instantaneous dissipative terms.

HOW TO EQUATE TESTS WITH LITTLE OR NO DATA

ETS Research Report Series, 1992
ABSTRACTStandard procedures for equating tests, including those based on item response theory (IRT), require item responses from large numbers of examinees. Such data may not be forthcoming for reasons theoretical, political, or practical. Information about items' operating characteristics may be available from other sources, however, such as content ...
