The potential of telecommunications technology to affect travel behavior has been perceived at least since the invention of the telephone. Fiction and nonfiction writers as far back as the 1870s speculated that such technologies would eliminate the need for travel to some extent. The spread of computers and information technology into the workplace, combined with the energy crises of the 1970s,...

Introduction: International travelers are exposed to health risks and may transmit infections before, during, or after travel. Travelers are expected to take vaccinations prior to travel. The current study assessed the factors associated with the practice of pre-travel vaccination among travelers departing through Addis Ababa Bole International Airport after their stay in Ethio...

Introduction: Travel agencies may be consulted by intending travelers seeking pre-travel health advice. Travel agents should be equipped to deal with such queries and have access to a source of high quality travel health advice. This study aimed to establish the level of knowledge of travel health risks among Irish travel agencies. Methods: A web-based su...

Introduction: Preparedness for the prevention of travel-related infectious diseases among Malaysian international travelers has yet to be explored. With no such data, health programs to empower travelers on behavioral responses towards travel-related illnesses will be ineffective. The current study aimed to develop and validate a new scoring-based instrument measuring Malaysian...

We present an approximation algorithm for the Traveling Salesman Problem when the vehicle is constrained to move forward along paths with bounded curvature (Dubins’ vehicle). A deterministic algorithm returns in time O(n3) a tour within (( 1 + max { 8πρ Dmin , 14 3 }) log n ) of the optimum tour, where n is the number of points to visit, ρ is the minimum turning radius and Dmin is the minimum E...

Introduction: The number of foreign travelers arriving in India has shown an exponential increase from 1.2 million in 1981 to 8.03 million in the year 2015, with an annual growth rate of 4.5%. With the influx of internationally mobile students to developing countries such as India comes the responsibility of having to cater to the health needs of these visitors. The current stu...
