We discuss what constitutes an integrated system in AI, and why AI researchers should be interested in building and studying them. Taking integrated systems to be ones that integrate a variety of components in order to perform some task from start to finish, we believe that such systems (a) allow us to better ground our theoretical work in actual tasks, and (b) provide an opportunity for much-n...

The Perilipin homologue LSD2 has been identified as a regulator of microtubule motor activity in Drosophila embryos. LSD2 is required for the net directional transport of lipid droplets and the new data support a model in which the protein imparts bias onto a molecular toggle that otherwise randomly engages minus and plus end motors in a paired set.

The discourse manager is the component of the TRIPS-98 system that maintains a list of candidate antecedents to be used for resolving anaphoric referring expressions. The model currently implemented in the system is a monologue-based model of context that has a variety of limitations. This paper discusses changes to the underlying model to make it handle a much broader range of referring expres...

Since through trips can be a significant portion of travel in a study area, estimating them is an important part of travel demand modeling. In the past, through trips have often been estimated using external surveys. Recently, external surveys were suspended in Texas, so Texas transportation planners need a way to estimate through trips without using external surveys. Previous research has focu...

Automobile use is a significant contributor to climate change, local air pollution, pedestrian injuries and deaths, declines in physical activity and obesity. A significant proportion of car use is for short trips that can relatively easily be taken with active transportation options--walking or cycling--or with public transportation. In this commentary, we review a number of immediate, practic...

In this paper, we propose a set of DSP extensions to the TRIPS ISA and evaluate their performance. By extending the TRIPS ISA with specialized DSP instructions, we offer an explorative look at the interaction conventional specialization techniques (such as SIMD instructions) have with EDGE ISAs. We discuss the implementation and its feasibility and provide non-intrusive compiler support through...

The authors propose a Multi Attributes approach to meet the demand of personalized tourist tours into cultural cities. Respecting to others works present into the literature, in this paper the decisional process includes two phases and a high number of variables that don’t increase the complexity of the problem. A real application in an Italian city, Florence, is presented to demonstrate the gr...

A n understanding of travel patterns is of key interest to transportation planners, researchers, engineers and policy analysts. The concern with the environment and traffic congestion and the focus on the balance between available supply and the resulting demand in view of the scarcity of fiscal resources has strengthened the need to better monitor travel behavior. This research uses traffic co...

iii Foreword Intellectual property is becoming increasingly important to agricultural trade. The success of Australian agriculture may be determined more in the future by our ability to engage in effective marketing and product innovation, than our ability to continue to improve yields. If this is the case, the international rules governing the trade aspects of intellectual property are importa...
