ACM Transactions on Spatial Algorithms and Systems, 2015
Due to the proliferation of GPS-enabled devices in vehicles or with people, large amounts of position data are recorded every day and the management of such mobility data, also called trajectories, is a very active research field. A lot of effort has gone into discovering “semantics” from the raw geometric trajectories by relating them to the spatial ...

Trajectory engine: a backend for trajectory sampling
NOMS 2002. IEEE/IFIP Network Operations and Management Symposium. ' Management Solutions for the New Communications World'(Cat. No.02CH37327), 2003The management of communication networks increasingly requires detailed knowledge of network usage, acquired by direct measurement. We report on the design and implementation of a backend system for trajectory sampling, a method for consistent sampling of packets across a network domain.

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 ...

Trends in Cognitive Sciences, 2016
In a recent Opinion article, Sui and Humphreys [1] argue that experimental findings suggest self is ‘special’, in that self-reference serves a binding function within human cognitive economy. Contrasting their view with other functionalist positions, chiefly Dennett's [2], they deny that self is a convenient fiction and adduce findings to show that a ...

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.

Archives of Pediatrics & Adolescent Medicine, 1977
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

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 ...

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 ...
