Vehicular Ad-Hoc Networks (VANETs) have a highly dynamic network topology due to the constant and rapid movement of vehicles. Therefore, communication in VANETs is mostly affected with disruptions and delays as a result of network disconnections and partitions. Moreover, increasing the geographical coverage area for data dissemination while keeping the data-delivery delay low is a challenge. Th...

BACKGROUND Thailand has achieved remarkable improvement in health status since the achievement of universal health coverage in 2002. Health equity has improved significantly. However, challenges on health inequity still remain.This study aimed to determine the trends of geographical inequalities in disease specific mortality in Thailand after the country achieved universal health coverage. ME...

In this paper we develop and test an encompassing theoretical framework for the explanation of the geographical and temporal spread of extreme right violence. This framework combines internal precipitating factors related to ethnic competition, social disintegration, and political opportunity structures, which make certain localities more prone to exhibit ethnic violence, with diffusion variabl...

Over the past two centuries, surveillance technology has advanced in three major spurts. In the first instance the surveillance instrument was a specially designed building, Bentham’s Panopticon; in the second, a tightly controlled television network, Orwell’s Big Brother; today, an electronic human-tracking service. Functionally, each technology provided total surveillance within the confines ...

Malaria fever is one of two mosquito-borne diseases still being reported in Malaysia. This study aims to visualize the geographical distribution of Malaria cases in Peninsular Malaysia from 1998 to 2010 using Geographical Information System (GIS). The pattern of malaria case distribution in Peninsular Malaysia for the duration between 1998 and 2010 is represented by shaded maps. The total malar...

Taking the Guangxi Beibu Gulf Economic Zone as the study area, this paper utilizes the geographical detector model to quantify the feedback effects from the terrestrial environment on precipitation variation from 1985 to 2010 with a comprehensive consideration of natural factors (forest coverage rate, vegetation type, terrain, terrestrial ecosystem types, land use and land cover change) and soc...

This study examines the effects of location inaccuracies on two static sensor deployment and reconfiguration algorithms, Coverage-Preserving Node Scheduling Scheme (CPNSS) and Optimal Geographical Density Control (OGDC) algorithms, developed by Tian et al. 2002 and Zhang and Hou (2003) respectively. For the purposes of examining the extent to which the deployment and reconfiguration algorithms ...

Background and objectives: The regionalization is a suitable approach to reduce the cost of health services and to increase the number of patients covered by special services. Since the establishment of the Neonatal Intensive Care Unit (NICU) needs expensive equipment and experts, it is critical to find the optimal number and location for NICU beds and referral networks. <stro...
