This paper describes the concept and implementation of a collaborative learning platform for school education over the Internet. The authors called this platform the "eTrip System," because they applied it to a school field study. Using information technologies, it supports the whole learning flow for a field trip: pre-trip learning; hands-on learning; and post-trip learning. It enables student...

One of the main aspects in the consumer behavior is the concept of involvement because it influences the decision rules used by tourists to reach the final decision. An empirical study of 600 international tourists reveals that motivation to relax, influences tourists’ involvement with the trip. A structural model shows that when tourists are motivated to relax they get directly more involved w...

Because trip-related falls account for a significant proportion of falls by patients with amputations and older adults, the ability to repeatedly and reliably simulate a trip or evoke a trip-like response in a laboratory setting has potential utility as a tool to assess trip-related fall risk and as a training tool to reduce fall risk. This paper describes a treadmill-based method for deliverin...

The traditional approach to urban travel analysis includes a detailed and complex modeling system that considers activity/trip generation (including time-of-day of trip) and destination, mode, and route choices. While the insights that one can gain from such a comprehensive approach are undeniable, a more simplistic approach that focuses on travel time alone (which by its nature will implicitly...

Traditional traffic counting location (TCL) problem is to determine the number and locations of counting stations that would best cover the network for the purpose of estimating origin-destination (O-D) trip tables. It is well noted that the quality of the estimated O-D trip table depends on the estimation methods, an appropriate set of links with traffic counts, and the quality of the traffic ...

Understanding the end-to-end packet delay dynamics of the Internet is of crucial importance since it directly affects the QoS (Quality of Services) of realtime services, and it enables us to design an efficient congestion control mechanism. In this paper, we measure the round-trip time, and build a mathematical model representing its dynamics using system identification. We first measure, as th...

Open Software Foundation's Distributed Computing Environment (OSF/DCE) [8] is a platform for distributed computing. DCE is a collection of tools and services for the development, use, and maintenance of transparent distributed application systems. The communication paradigm supported by DCE is the synchronous Remote Procedure Call (RPC) [1]. RPCs can be implemented on any transport layer protoc...

In a peer-to-peer shared ride system, transportation clients with traffic demand negotiate with transportation hosts offering shared ride services for ad-hoc ride sharing in a continuously changing environment, using wireless geosensor networks. Due to the distinctive characteristic of this system—a complex and nondeterministic transportation network, and a local peer-to-peer communication stra...

In this paper, we introduce a new interesting path finding problem, which is the Skyline Trips of Multiple POIs Categories (STMPC) query. In particular, given a road network with a set of Points of Interest (POIs) from different categories, a list of items the user is planning to purchase and a pricing function for items at each related POI; find the skyline trips in term of both trip length an...

The return trip often seems shorter than the outward trip even when the distance and actual time are identical. To date, studies on the return trip effect have failed to confirm its existence in a situation that is ecologically valid in terms of environment and duration. In addition, physiological influences as part of fundamental timing mechanisms in daily activities have not been investigated...
