Abstract

This manuscript has been reproduced from the microfilm master. UMI films the text directfy from the original or copy submitted. Thus, some thesis and dissertation copies are in ^pewriter face, while others may be from aiqr type of conq)uter printer.Hie qnali^ of this reproduction is dependent upon the quali^ of the copy sabmitted. Broken or indistinct print, colored or poor quality illustrations and photogr^hs, print bleedthrough, substandard and in^oper aligmnent can adversefy affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note win indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overly. Each original is also photographed in one exposure and is included in reduced form at the back of the book.

Spatio‐Temporal Object‐Oriented Data Model for Disaggregate Travel Behavior

“…The Oogeomorph model (Raper and Livingstone 1995) endorses the use of OOP concepts in geomorphology. Other models that offer generic OO integrative solutions of the temporal and spatial dimensions include the IFO model (Worboys et al 1990), OOSTM model (Cheng and Gadia 1992), STDS model (Milne et al 1993), OOST versioning model (Wachowitcz and Healey 1994), SIDL model (Rojas-Vega and Kemp 1995), and the MADS model . Further details can be found in reviews provided by Abraham and Roddick (1999) and Renolen (2000).…”

An XML-based implementation of the parametric model for ad-hoc query of temporal and spatiotemporal data

“…Thus, in the context of spatial alignment [a] evaluates to ft, and in spatiotemporal context it evaluates to ft x 7 [10,16].…”

“…Since a tuplet is the part of a parametric tuple, it is not necessary to evaluate the tuplet if the previous tuplet has been already qualified. If this is not the case, the second step is to check whether the expression node is a unary node (line [5][6][7][8][9][10][11][12]. If this is the case, the expression node is a terminal node.…”

An XML-based implementation of the parametric model for ad-hoc query of temporal and spatiotemporal data

“…Second, if there is no more tuplet, it checks if there is no more tuple (line 6-9); if this is the case, it returns a message to indicate it reaches the end of a relation. Third, if there is an available tuple (line [10][11][12][13][14], it initializes the variables of the iterator and returns a message indicating that it has reached the end of a tuple.…”
