This paper gives an overview of mobile computing and issues related to the field. The discussion starts with definitions of various terms associated with mobile computing. The diversity of mobile applications is explored to give readers an idea of what mobile computing has to offer, followed by a discussion on the limitations of wireless networks and the issues which have to be addressed in ord...

This paper discusses an application layer framework that uses a set of standard IETF protocols for supporting real-time and non-real-time multimedia applications on mobile terminals of next generation wireless [3G/4G] networks. It describes a 3G-IP architecture and brings out the requirements and issues which are essential for supporting roaming users in the wireless Internet in a ubiquitous wa...

Free-roaming horse (Equus caballus) management is a complex issue incorporating social, economic, emotional, political, and environmental factors. Currently, few proven field techniques exist for managing free-roaming horse population growth, which can reach 20-25% annually. Although there are several strategies available for sterilizing mares when managing free-roaming horse populations, surgi...

BACKGROUND Rabies is an important but preventable cause of death in Ethiopia. We assessed the knowledge, attitudes and practices of animal bite victims attending an anti-rabies health center in Jimma Town, Ethiopia. METHODOLOGY/PRINCIPAL FINDINGS Between July 2012 and March 2013 a cross-sectional questionnaire was administered to 384 bite victims or their guardians in the case of minors (aged...

The Virtual Home Environment (VHE) has been introduced as an abstract concept enabling users to access and personalize their subscribed services whatever the terminal they use and whatever the underlying network used. The European IST VESPER project (Virtual Home Environment for Service Personalization and Roaming Users) aims to provide an architectural solution and an implementation of the VHE...

The emerging 3 generation services are provided through various types of networks and terminals. Roaming users rely on new kinds of wireless networks and terminals to offer mobility and make services available everywhere. The users’ requirement for continuous access to personalized services from any place, transparently and independently of the underlying network technology and the terminal or ...

Free-roaming dogs and rabies transmission are integrally linked across many low-income countries, and large unmanaged dog populations can be daunting to rabies control program planners. Dog population management (DPM) is a multifaceted concept that aims to improve the health and well-being of free-roaming dogs, reduce problems they may cause, and may also aim to reduce dog population size. In t...

Powerline rights-of-way (ROWs) often provide habitat for early successional bird species that have suffered long-term population declines in eastern North America. To determine how the abundance of shrubland birds varies with habitat within ROW corridors and with land use patterns surrounding corridors, we ran Poisson regression models on data from 93 plots on ROWs and compared regression coeff...
