Spontaneous language samples elicited during freeplay and interview contexts were compared for 10 children who were specifically language impaired (SLI). Clinician-child videotaped interactions were analyzed for both structural and conversational behaviors. The results indicated that the interview was a reliable and valid assessment context, eliciting the same profile of behaviors as the freepl...

Freeplay is one of the most important nonlinearities that affect the control surfaces of the aircraft; it can induce flutter phenomena and limit the performances of the same airplane. To investigate the effect of control surface freeplay, an aeroelastic wind tunnel model of a T-tail has been developed. A variable amplitude freeplay has been introduced in the control chain by a specifically desi...

objectives: the spontaneous language sample analysis is an important part of the language assessment protocol. language samples give us useful information about how children use language in the natural situations of daily life. the purpose of this study was to compare conversation, freeplay, and narrative speech in aspects of mean length of utterance (mlu), type-token ratio (ttr), and the numbe...

Abstract Tiltrotor aircraft are growing in prevalence due to the usefulness of their unique flight envelope. However, aeroelastic stability—particularly whirl flutter stability—is a major design influence that demands accurate prediction. Several nonlinearities may be present tiltrotor systems, such as freeplay, often neglected for simplicity, either modelling or stability analysis. effects can...

A typical two-dimensional airfoil with freeplay nonlinearity in pitch undergoing subsonic flow is studied via numerical integrationmethods.Due to the existence of the discontinuous nonlinearity, the classical fourth-order Runge-Kutta (RK4) method cannot capture the aeroelastic response accurately. Particularly, it is because the RK4 method is incapable of detecting the discontinuous points of t...

Both the dynamic characteristics and structural nonlinearities of an actuator will affect flutter boundary a fin–actuator system. The models used in past research are not universal, accuracy is difficult to guarantee, consideration nonlinearity adequate. Based on modularization, high-fidelity modeling method for proposed this paper. This model considers both freeplay friction, which easy expand...

Research regarding autonomous learning shows that freeplay does not result in optimal learning. Combining scenario-based training with intelligent agent technology offers the possibility to create autonomous training enriched with automated adaptive support delivered by a director agent. We conducted an experiment to investigate whether directing training scenarios improves the quality of train...

In this paper we describe the design process of an interactive accessory to play anywhere and anytime while encouraging free-play and practice social skills. We explain the design process, the resulting conceptual design of FeetUp and the preliminary user’s evaluation. FeetUp is a playful accessory that takes advantage of children’s interest to jump, or perform body stunts. These activities gen...
