Integrating Expert System and Geographic Information System for Spatial Decision MakingShesham, Sriharsha 01 December 2012 (has links)
Spatial decision making is a process of providing an effective solution for a problem that encompasses semi-structured spatial data. It is a challenging task which involves various factors to consider. For example, in order to build a new industry, an appropriate site must be selected for which several factors have to be taken into consideration. Some of the factors, which can affect the decision in this particular case, are air pollution, noise pollution, and distance from living areas, which makes the decision difficult. The geographic information systems (GIS) and the expert systems (ES) have many advantages in solving problems in their prospective areas. Integrating these two systems will benefit in solving spatial decision making problems. In the past, many researchers have proposed integrating systems which extracts the data from the GIS and saves it in the database for decision making. Most of the frameworks which have been developed were system dependent and are not properly structured. So it is difficult to search the data. This thesis proposes a framework which extracts the GIS data and processes it with the help of ES decision making capabilities to solve the spatial decision making problem. This framework is named GeoFilter. This research classifies various types of mechanisms that can be used to integrate these two systems.

Rening av avloppsvatten från biltvättar med filter av torv och inblandad kolaska : en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv / Treating sewage water from carwashes using a filter of peat and carbon-containing ash : an evaluation of efficiency and waste handling from an environmental perspectiveSöderlundh, Sussie January 2010 (has links)
<p>Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns.</p> / <p>Sewage water from two car washes has been treated during 2 and 4 years respectively, using a filter made of 75 % peat and 25 % carbon-containing ash. A comparison with the guiding values for car wash sewage water in Kristianstad municipality shows that this type of filter works well. Classification of the filter as waste requires knowledge about the content of environmentally harmful substances in products used in the car washes. Because of the lack of knowledge about the content of non-analyzed substances in the filters, combustion must be regarded as an environmentally good way of disposing the filter material, as both energy and ashes are recycled.</p>
