This paper focuses on the use of geographic information system (GIS) in gender research and argues for the possibility that the tool has inherent biases with regard to data collection and representation. Introduction Given the mandate by large agencies to address gender in all development projects and the „Mainstreaming of Gender‟ at the World Bank, we can expect that new opportunities will eme...

The purpose of this paper is to study some statistical problems : parameter estimation, binary detection , change detection (disorder problem), etc. for partially observed diiusion processes, using the likelihood approach. It is shown that the stochastic PDE related to the state estimation problem, provides also a way to compute the likelihood function/ratio. A recent result on consistency of t...

Automatic change detection particularly in urban areas is the important tools for their management and planning. This paper presents a feature based method to detect changes in urban area using two LIDAR data sets acquired at different times. The main processes in the method are to detect the change areas through the subtraction between the two DSMs generated from the two individual LIDAR sets,...

An original approach for real time detection of changes in motion is presented, for detecting and recognizing events. Current video change detection focuses on shot changes, based on appearance, not motion. Changes in motion are detected in pixels that are found to be active, and this motion is input to sequential change detection, which detects changes in real time. Statistical modeling of the...

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

Geographic Information System (GIS) is a computerbased tool used extensively to solve various engineering problems related to spatial data. In spite of growing popularity of GIS, its complete potential to construction industry has not been realized. In this paper, the summary of up-to-date work on spatial applications of GIS technologies in construction industry is presented. GIS technologies h...

GIS (Geographic Information System) usability is one of the most significant factors of government sectors like the Ministry of Environment, Planning, Forestry, Fisheries, and so on. In this paper, we present a methodology for evaluating the usability of GIS software. We demonstrate how to find out the severity ratings of problems in GIS software. A sample GIS user Interface prototype is design...

Visualization has become an integral part in many applications of GIS. Due to the rapid development of computer graphics, visualization and animation techniques, general-purpose GIS can no longer satisfy the multitude of visualization demands. Therefore, GIS have to utilize independent visualization toolkits. This article examines how visualization systems can be used with and integrated into G...

The current lack of error-sensitive functionality found in commercial GIS is at odds with the research focus error-sensitive GIS development has enjoyed over recent years. In an attempt to address this undesirable situation, this paper reviews a number of key error-sensitive GIS research themes, based on experience gained during a three year research project into errorsensitive GIS development....

A GIS (Geographic Information System), is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. In other words, GIS is the merging of statistical analysis, database technology and cartography that can be integrated into any enterprise information system framework. But despite all these advantages, geographic information system...
