On the basis of the tree-regular language theory, we study document transformation and schema transformation. A document is represented by a tree t, and a schema is represented by a tree-regular language L. Document transformation is de ned as a composition of a marking function mPC and a linear tree homomorphism h, where P is a pattern and C is a contextual condition. Pattern P is a tree-regul...

Location services are used in mobile ad hoc and hybrid networks either to locate the geographic position of a given node in the network or for locating a data item (content). One of the main usages of position location services is in location based routing algorithms. In particular, geographic routing protocols can route messages more efficiently to their destinations based on the destination n...

in large multimedia databases and make inferences about the data stream’s content. A human operator can specify gross indices, such as the date or hour, and perhaps the location and the activity (for example, a football game) at the time of capture. Finer-grain annotations require separating the video into meaningful segments such as shots and scenes. Many automated techniques and annotation fo...

BACKGROUND Upper extremity (UE) region-specific, patient-reported outcome (PRO) scales assess injuries to the UE but do not account for the demands of overhead throwing athletes or measure patient-oriented domains of health-related quality of life (HRQOL). PURPOSE To develop the Functional Arm Scale for Throwers (FAST), a UE region-specific and population-specific PRO scale that assesses mult...

Multimedia streaming means delivering continuous data to a plethora of client devices. Besides the actual data transport, this also needs a high degree of content adaptation respecting the end users‘ needs given by content preferences, transcoding constraints, and device capabilities. Such adaptations can be performed in many ways, usually on the media server. However, when it comes to content ...
