given the critical role played by urban green spaces and the emergence of remote sensing as avaluable natural resource management tool, this study sought to identify trends in green spaces within thecontext of south africa’s transition period (1990 - 2000). using the city of port elizabeth as a case study, threesets of landsat - 5 thematic mapper images (1990, 1995 and 2000) were geo-processed,...

Despite the last decade’s research and new insights into human-machine communication, much of today’s technology is too complicated to use, e.g., [6]. This is true for consumer electronics as well as household devices—much of the cutting-edge products do not fit in an every-day environment for every-day users. Current home automation solutions are for technophile users. The lack of intuitive or...

We propose an approach to remote display systems in which the client predicts the screen update events that the server will send and applies them to the screen immediately, thus eliminating the network round-trip time and making the system more responsive in a wide-area or high loss environment. Incorrectly predicted events are undone when the actual events arrive from the server. The approach ...

People with special needs may find difficulties using electronic consumer devices, user interfaces limit their chances of having full control on them. The Universal Remote Control (URC) is an ISO standard that promotes pluggable and interoperable user interfaces to remotely operate electronic devices. The Universal Control Hub (UCH) is the software architecture that materialises URC, and severa...

in this paper, new definitions of $l$-fuzzy closure operator, $l$-fuzzy interior operator, $l$-fuzzy remote neighborhood system, $l$-fuzzy neighborhood system and $l$-fuzzy quasi-coincident neighborhood system are proposed. it is proved that the category of $l$-fuzzy closure spaces, the category of $l$-fuzzy interior spaces, the category of $l$-fuzzy remote neighborhood spaces, the category of ...

Simulated use of IP applications on hosts spread on the internet is expensive, which leads already in simple use cases to an enormous amount of time for setting up and carrying out an experiment. Complex scenarios are only possible with an additional infrastructure. This document describes a framework with which a needed infrastructure can be implemented. This infrastructure allows an efficient...

the objective of this study is to develop a novel methodology integrating remote sensing, geographic information system technology and local spatial autocorrelation geo-computation for quick drought assessment. one group of drought indices, based on the condition of the vegetation, includes the normalized difference vegetation index (ndvi), anomaly of normalized difference vegetation index (ndv...

the reflectance spectrum of green leaves is considerably affected by their biochemical and biophysical properties. it is possible to extract biochemical information from a continuous vegetation spectrum produced using hyperspectral sensors. the numerous absorption features present in the vegetation spectrum carry a considerable amount of information related to the content and the structure of t...

the objective of this research was to determine the best model and compare performances in terms of producing landuse maps from six supervised classification algorithms. as a result, different algorithms such as the minimum distance ofmean (mdm), mahalanobis distance (md), maximum likelihood (ml), artificial neural network (ann), spectral anglemapper (sam), and support vector machine (svm) were...

the drought caused a series of effects on many sectors of economy, especially natural resources. during two last decades, iran has suffered from several severe to extreme agricultural droughts which caused significant decreases in rangeland and agriculture yields. this paper discusses the detection of agricultural drought severity over the rangelands of markazi province between 2000 and 2014 us...
