in order to assess the prevalence of echinococcus granulosus (eo) infection (hydatidosis) in nomadic tribes of southern iran, 1000 individuals from a total population of 1 12,519 were selected by randomized single blind cluster sampling method and studied from 1994- 1995. the study included: ( l ) a physical examination by a gastroenterologist, (2) abdominal ultrasonography (us), and (3) detect...

A study was carried out to determine the prevalence of parasitic infections among the nomadic Fulanis of south-eastern Nigeria between September 2003-March 2004. Urine, stool and blood specimens were collected from each of 231 subjects. Of these, 98 (42.4%) were infected with one or more of 14 parasitic species, of which Plasmodium malariae had the highest prevalence (15.3%). Others included 6 ...

* Mike Scaife died suddenly and unexpectedly while we were revising the paper. His contribution to the research was instrumental. ABSTRACT Nomadic team working involves close-knit groups collaborating over a large geographical space performing time-critical tasks. We present an ethnographic study of the way a dispersed team of technicians coordinate their work, highlighting the phenomenon of ex...

During the last years, the application of different wireless technologies has been explored in order to enable Internet connectivity from vehicles. In addition, the widespread adoption of smartphones by citizens represents a great opportunity to integrate such nomadic devices inside vehicles in order to provide new and personalized on trip services for passengers. In this paper, a proposal of c...

This paper presents the design and implementation of Ferret, a system for locating nomadic augmented with RFID tags and visually displaying them to a user in real-time. We present a novel algorithm to infer location of tagged objects using the location of a camera and reader that observes them. We also present techniques to refine location estimates using multiple observations and a method to d...

In this study we revisit Weiser’s (1991) [5] vision of seamlessly integrated computing. We focus on nomadic workers who rely extensively on mobile technologies to conduct work. Using Star and Ruhleder’s (1996) [10] properties of infrastructure, we discuss how nonroutine users of infrastructure face particular challenges. We conducted an ethnographic investigation of nomadic workers in a large d...

Multi-population GAs are found to be more efficient than Standard Genetic Algorithm (SGA) in terms of convergence as well as reliability of results. Nomadic Genetic Algorithm (NGA) is a kind of multi-population GA wherein individuals keep migrating from one subpopulation to another based on their fitness. It has been proved to be very effective in improving the performance of single population ...

The convergence of Web technology, wireless networks, and portable client devices provides new design opportunities for computer/communications systems. In the HP Labs’ “Cooltown” project we have been exploring these opportunities through an infrastructure to support “web presence” for people, places and things. We put web servers into things like printers and put information into web servers a...

PROBLEMS ADDRESSED With the advent of nomadic and home office environments, remote access security is once again taking its place at the forefront of security planning activities. Everyone wants an Internet presence and Internet access. Telecommuting is gaining in popularity. Sales agents armed with laptops roam the countryside. Opening up systems to casual access by nomadic and home office wor...

With the recent advances in mobile computing, distributed organizations are facing a growing need for advanced Information and Communication Technologies (ICT) that support mobile working. The ability to use information effectively anywhere and anytime has become a key business success factor. Although many Computer Supported Collaborative Work (CSCW) systems have been introduced to date, techn...
