The Tilt Model Acoustic Survey of Intonation in Children with Severe Autism

<p>The purpose of this study is an acoustic survey of intonation in a set of declarative and interrogative sentences as uttered by 15 children with severe autism (SA) in comparison with 15 Typically Developing (TD) children. The results indicate that monotony is not a common feature in the speech pattern of all autistic children. More specifically, the results demonstrate that the monotony attributed to the autistic children’s production of speech cannot be attributable to all kinds of sentences they produce as they can produce statements and questions fairly similar to typically developing children.</p>

Study on Tilt Model and Finite-Element Simulations on Roller Leveler

According to the adjustment process of wide plate roller leveler of the cross cut shearing line, tilt model during leveling was established with ANSYS/LS_DYNA, which is one of the dynamic FE analysis software. The leveling effect on plate shape quality with or no with tilt model was analyzed respectively. The simulation results indicated the tilt model can get the more equivalent stress distribution and reduce the residual stress, which improve the straightness quality of the plate. In addition, the leveling force of each work roll can be decreased with tilt model. This is very beneficial to increase the production output of the leveler.

Integration of Distributed Robotic Systems

Creating a distributed and remote operated robotic system is a very challenging and time-consuming task. This paper contains the development issues taking into account when multiple robotic components are integrated to create a distributed robotic application using the standard middleware, Common Object Request Broker Architecture (CORBA) specification. The main idea is to define a set of generic interfaces using the Interface Definition Language (IDL) that can be used with common components in order to facilitate the integration of new components or the modification of them. The generic IDL interfaces are based on wrapper functions, which provide an abstract encapsulated behaviors of the low level components. The approach is shown using two types of arm manipulators and two different pan-tilt model units. Because of the modularity and the abstraction of this approach, this development can be seen as the first stage in constructing more autonomous and complex system.
