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 various applications, and it enables us to design an efficient congestion control mechanism. In our previous studies, we have measured round-trip time of the Internet, and have modeled its dynamics by the ARX (Auto-Regressive eXogenous) model usi...

We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem using a lexicographic bi-criteria optimization method where least squares minimization is applied to the measured counts and the minimum information or the maximum entropy approach to the whole matrix. An elevator trip consists of successive stops in one direction of travel with pa...

BACKGROUND Japanese encephalitis virus (JEV) is the major cause of viral encephalitis in Southeast Asia. Vaccination of domestic pigs has been suggested as a "one health" strategy to reduce viral disease transmission to humans. The efficiency of two lentiviral TRIP/JEV vectors expressing the JEV envelope prM and E glycoproteins at eliciting protective humoral response was assessed in a mouse mo...

Public transport systems are vital services in urban environments. The design of these complex socio-technical is continuously evolving to accommodate larger populations, and their adaptation essential supporting the successful sustainable development cities regions. An part this includes working increase passenger safety minimise risk injury. With focus, key objectives current study were ident...

A combined experimental numerical approach is applied to determine the transformation induced plasticity (TRIP)-parameter K for different strength low-alloy steels of grade S355J2+N and S960QL as well as the super martensitic filler CN13-4-IG containing 13 wt% chromium and 4 wt% nickel. The thermo-physical analyses were conducted using a Gleeble (®) 3500 facility. The thermal histories of the s...

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...
