The ubiquity of location-data-enabled devices provides novel avenues for psychology researchers to incorporate spatial analytics into their studies. Spatial use global positioning system (GPS) data assess and understand mobility behavior (e.g., locations visited, movement patterns). In this tutorial, we provide a practical guide analyzing GPS in R introduce key procedures resources conducting a...

In Image Database Systems, symbolic pictures are represented by 2D stringsthat are converted into triples. Each triple is mapped to a unique hash addressfor timely retrieval of pictures, reducing the pattern-matching problem cor-responding to a query to that of computation of hash function. The valuesassociated with the picture objects are used to compute hash addresses fort...

INTRODUCTION Paediatric acute epiglottitis is rare in Asia. The National University Hospital in Singapore has seen only two cases of paediatric acute epiglottitis in the last 10 years. The topic is re-visited here to remind physicians of its acutely dramatic progression. CLINICAL PICTURE Both boys presented with a viral prodrome which progressed within hours to life-threatening upper airway o...

On July 13, 1992 a team of researchers from the BFS visited Kashong Bay in order to provide a characterization of the benthic community prior to expected impacts by the then recent introduction of the zebra mussel, Dreissena polymorpha (Harman, 1993a). A transect was erected perpendicular to the shoreline from the eulittoral zone (beach) to 25 feet in depth. Inspection by SCUBA was used to coll...

this paper considers the spatial planning system in russian federation. study of spatial planning system of russia specifies three different stages from each other. the first phase consists of the sixteenth century until the early twentieth century. in this period, base of the spatial planning was formed and gradually developed during approximately 400 years. the next phase is devoted to soviet...

We present a novel interactive visualization scheme for state-based hypertension progression modeling using hidden Markov models, applied to electronic health records of a cohort population enrolled in a hypertension management program. The visualization tool provides an interface for exploratory analysis and model validation, and improves the interpretability of the model results for healthcar...
