Journal of Documentation, 1992
Describes the fate of 101 manuscripts rejected by the Journal of Documentation during the years 1981–1989. More than a quarter were subsequently traced in the literature. The majority of re‐submitted articles appeared in journals with a lower impact factor. The limitations of the study and the methodology are acknowledged.

IEEE Transactions on Systems, Man, and Cybernetics, 1993
A simple algorithm for selecting and linking interesting flow vectors across a sequence of frames for computing motion trajectories is presented. Tokens are tracked that have both interesting pixel gray values in the spatial domain and in the optical flow field in the temporal domain.

Knowledge and Information Systems, 2019
With continued development of location-based systems, large amounts of trajectories become available which record moving objects’ locations across time. If the trajectories collected by different location-based systems come from the same moving object, they are spliceable trajectories, which contribute to representing holistic behaviors of the moving ...

International Journal of Computer Mathematics, 1999
We introduce and investigate a new way of generating mildly context-sensitive languages. The main idea is that the contexts are adjoined by shuffling them on certain trajectories. In this way we obtain also a very general class of contextual grammars such that most of the fundamental classes of contextual gram-mars, for instance, internal contextual ...

In this paper, we present an OLAP framework for trajectories of moving objects. We introduce a new operator GROUP_TRAJECTORIES for group-by operations on trajectories and present three implementation alternatives for computing groups of trajectories for group-by aggregation: group by overlap, group by intersection, and group by overlap and intersection.

Journal of Adolescence, 2013
AbstractThis special section brings together five studies using group‐based modeling to capture developmental trajectories of loneliness from age 7 through age 20. Together, the findings from these studies provide further evidence that developmental trajectories of loneliness are likely not best understood at a continuum but reflect distinct ...

Proceedings. 1991 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2002
A solution to the correspondence problem using constraint satisfaction is described. It uses a real-time line-fitting algorithm to detect changes in a point's motion parameters as they happen. A trajectory is hypothesized for a single point's motion. Since the event detected may be wrong, multiple trajectories are hypothesized for each point.

Developmental medicine is the science of biographies, and from its inception the biography of each infant is unique. When one considers rate of growth in utero alone, great divergence is shown. Among different ethnic groups weight at birth ranges from a mean of 2.4 kg for the neonates of the Lumi tribe in the Toricelli mountains of New Guinea to a mean
