OBJECTIVE This study investigated the contribution of perceptual-motor dysfunction and cognitive planning problems to the quality or speed of handwriting in children with handwriting problems (HWP). METHOD Twenty-nine children with HWP and 20 classroom peers attending regular schools (grade 2 and grade 3) were tested with regard to visual perception, visual-motor integration, fine motor coord...

Spatio-temporal querying and retrieval is a challenging task due to the lack of simple user interfaces for building queries despite the availability of powerful indexing structures and querying languages. In this paper, we propose Query-by-Gaming scheme for spatio-temporal querying that can benefit from gaming controller for building queries. By using Query-by-Gaming, we introduce our spatio-te...

The spectacular evolution of sensor networks and the proliferation of location-sensing devices in daily life activities are leading to an explosion of disparate spatio-temporal data. The collected data describes the movement of mobile objects used to construct what we call trajectory data. The diversity of these generated data has led to a variety of spatio-temporal models. In fact, the concept...

The concept and applications of spatio-temporal optical computing are proposed. This concept introduces ordinary spatial optical computing techniques using Fraunhofer and Fresnel diffraction into time domain. The concept is classified in three phases. The first phase employs spatiotemporal duality of light. In this thesis a new algorithm to analyze low coherence interferograms is proposed in th...

The relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the Netherlands. For a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. A Generalized Additive Model was employed to find relationships between the various factors inf...

Spatio-temporal local feature based bag of visual words algorithm (BOVW) has shown promising results in complex human action classification. However, one key disadvantage of BOVW is geometrical unconstraint, which makes it impossible to recognize different actions with the same features but different spatial-temporal distribution of these features. In this paper, we exploit the spatio-temporal ...

Integrating spatio-temporal data as abstract data types into already existing data models is a promising approach to creating spatio-temporal query languages. Based on a formal foundation presented elsewhere, we present the main aspects of an SQL-like, spatio-temporal query language, called STQL. As one of its essential features, STQL allows to query and to retrieve moving objects which describ...
