Conceptual Design of an Activity-based Spatio-temporal Data Model for Epidemics Transmission Analysis
نویسندگان
چکیده
Recently GIS have been used in the surveillance and monitoring of diseases and control of epidemics. Most of those mapping systems use aggregated datasets. This aggregated datasets are not sufficient to support the analysis of epidemiological transmission if the disease is spread mostly person by person from region to region such as SARS Severe acute respiratory syndrome. This paper develops a mobility-oriented spatio-temporal data model to support SARS transmission analysis in a GIS environment by identifying spatial and temporal opportunities for activity participation. The model can support the tracing and predication of spatially varying, temporally dynamic and individually based epidemiological phenomena. A prototype system based on the data model is implemented by a case study based in Hong Kong.

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...

متن کاملSpatio-temporal agent based simulation of COVID-19 disease and investigating the effect of vaccination (case study: Urmia)
Proper management of epidemic diseases such as Covid-19 is very important because of its effects on the economy, culture and society of nations. By applying various control strategies such as closing schools, restricting night traffic and mass vaccination program, the spread of this disease has been somewhat controlled but not completely stopped. The main goal of this research is to provide a f...
متن کاملThe Spatio – Temporal Process Model
Spatio-temporal models are crucial for performing assumption and predictions for physical, environmental, space and biological science. Typical application examples include traffic monitoring, regional ozone monitoring, disease mapping and analysis of satellite data. This paper discusses the construction of a conceptual model for spatio – temporal processes based on the concepts of concurrent p...
