Users of augmentative and alternative communication (AAC) aids could benefit from novel methods for accelerating access to contextually relevant vocabulary. This paper describes our initial efforts toward improving access to situational vocabulary through the use of geographic context to predict vocabulary. A corpus of spoken data produced by one able-bodied male speaker across various location...

Spatial Data Infrastructures at national or higher levels usually comprise the access to multiple geographic data catalogs. However, with classical search systems, it is difficult to have a clear idea of the information contained in the metadata holdings of these catalogs. This paper describes a set of clustering techniques to create a thematic classification of geographic resource collections ...

BACKGROUND A quantitative measurement of inequality in geographic accessibility to pediatric care as well as that of mean distance or travel time is very important for priority setting to ensure fair access to pediatric facilities. However, conventional techniques for measuring inequality is inappropriate in geographic settings. Since inequality measures of access distance or travel time is str...

The liver transplant allocation system is currently based upon the Model for End-Stage Liver Disease (MELD) score and allocates organs preferentially to patients with the highest scores (ie, the sickest patients) within a defined geographic unit. In addition, certain patient populations, such as patients with hepatocellular carcinoma and portopulmonary hypertension, receive MELD exception point...

Hedonic property price models have been used extensively in the economics literature to measure the value households place on locating properties close to a given resource, such as a beach, river, or lake. This proximity premium consists of two components. First, property owners derive benefit from living close to the resource for access purposes. Second, they also derive benefit from the view ...

Grid Geospatial Information Service (Grid GIS) system aims to study and develop grid-based uniform spatial information access and analysis system. Data resources of Grid GIS include not only original and traditional GIS data but remotely sensed data. Analysis function is made up of not only single spatial information access but complex and quick data processing. The Grid GIS system can provide ...

This paper examines the constraints that limit the large-scale adoption of open source GIS. Although the open source GIS community has already achieved relevant results, their products have a small market share. There is equivalent to Linux and Apache in the open source GIS scene. We try to explain why this happens, by considering some factors that control the evolution and adoption of open sou...

In Wireless Sensor Networks (WSNs) the majority of the devices provide access to the Received Signal Strength Indicator (RSSI), which has been used as a means to enable different services and applications like localization, geographic routing and link quality estimation. Notwithstanding the popularity of using RSSI for localization, academic research showed that RSSI-based distance estimate is ...
