In this interesting paper Professor Nikiforov reviewed the current state of quickest change detection/isolation problem. In our discussion of his paper we focus on the concerns and the opportunities of the subfield of quickest change detection, or more generally, sequential methodologies, in the modern

ISPRA, on behalf of the Italian Ministry of Environment, carried out the initial assessment of environmental quality status of the 3 Italian subregions (Mediterranean Sea Region) on Descriptor 9. The approach adopted to define the GES started to verify that contaminants in fish and other seafood for human consumption did not exceed levels established by Community legislation (Reg. 1881/2006 and...

This paper demonstrates an integrated method for studying cropland loss dynamics and the resultant impacts on sustainable development spanning the past 10 years (1996–2006) in response to rampant urban growth. This study deploys remote sensing to obtain accurate measures of cropland change information and applies GIS to examine the spatio-temporal trajectory of cropland loss. Coupled with lands...

BACKGROUND Since the late 1980s, the policy of the Japanese government regarding physician manpower has been to decrease the number of medical students. However, the shortage of doctors in Japan has become a social problem in recent years. The aim of this study was to compare the numbers of physicians in Japan between 1996 and 2006 and the trends in distribution of physicians. METHODS The tim...

Collaborative spatial decision support systems (C-SDSS) have been used to help groups of stakeholders understand data and search for opportunities at resolving local and regional decision problems in various domains including land use, transportation, and water resources. The key issue in designing an effective C-SDSS is the anticipation of user information needs. Knowledge of user information ...

The present study aims to develop a new hybrid Fuzzy Simulink model to assess the groundwater quality levels in Tiruchirappalli city, South India. Water quality management is an important issue in the modern times. The data collected for Tiruchirappalli city have been utilized to develop the approach. This is illustrated with seventy nine groundwater samples collected from Tiruchirappalli city ...

TANNER, B.R.; PERFECT, E., and KELLEY, J.T., 2006. Fractal analysis of Maine’s glaciated shoreline tests established coastal classification scheme. Journal of Coastal Research, 22(5), 1300–1304. West Palm Beach (Florida), ISSN 0749-0208. Average fractal dimensions (D) are calculated for Maine’s four coastal compartments using a GIS approach and digitized U.S. Geological Survey 7.5-minute series...

A geographic information system (GIS) allows a user to combine digitized data sets from multiple sources to produce a customized map. Like traditional paper maps, GIS maps should be accurate. Unlike traditional maps, however, technical limitations raise new ethical issues for geographic information systems. These technical limitations include unavoidable inaccuracies introduced by the digitizat...

This paper falls into a common field of scientific research and its practical applications at the interface of urban geography, environmental criminology, and Geographic Information Systems (GIS). The purpose of this study is to identify types of different land use which influence the spatial distribution of a set of crime types at the intra-urban scale. The originality of the adopted approach ...

In recent years, modeling has emerged as an invaluable tool for understanding the functioning of coastal lagoons. Modelling the environmental characteristics of the coastal area near the Bay of Bengal, India has received increasing attention from researchers in the past years. This interest has stimulated a scientific investigation of lagoon ecosystems, which have been studied from the physical...
