   Författare :Mats Svensson; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; Spectral Analysis of Surface Waves; shear modulus; SASW; multichannel; inversion; Gmax; teknisk geografi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; geographical and geological engineering; Hydrogeology; Civil engineering; hydraulic engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : With the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing. LÄS MER

3. 22. Regional gravity and auxiliary geophysical measurements in the Songkhla, Yala and Pattani provinces in the peninsular Thailand and their geological interpretation

   Författare :Warawutti Lohawijarn; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : A regional gravity survey and VES measurements were carried out in Songkla-Yala-Pattani provinces of Peninsular Thailand, an area between latitudes 6º 15'N and 7º 15'N and longitudes 100º 15'E and 101º 30'E. In addition the aeromagnetic maps of the area have been analyzed qualitatively as well as quantitatively in this thesis, an analysis that has not been undertaken before this. LÄS MER

4. 23. On leachate emissions from municipal solid waste

   Författare :Martijn van Praagh; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; Miljöstudier; Environmental studies; Environmental Impact; heavy metals; Organic carbon; teknisk geologi; Hydrogeologi; geographical and geological engineering; teknisk geografi;

   Sammanfattning : When attention is drawn to the recovery of resources within waste, the amount and types of waste disposed of at landfills change. A waste management system based on separate kerbside collection, sorting, recycling, and pretreatment with material and/or energy recovery produces new residues, which finally end up at landfills.

5. 24. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)

   Författare :Aman Mohammad Kalteh; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Self-organizing map; Feed-forward multilayer perceptron; Forecasting; Hydrological modelling; Missing values; Rainfall-runoff modelling; Estimation; Artificial neural networks;

   Sammanfattning : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. LÄS MER

7. 25. Automated performance monitoring of concrete dams

   Författare :Christian Bernstone; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; geographical and geological engineering; Maintenance; Uplift pressure; Crack; Deformation; Image processing; Dams; Condition monitoring; Time-domain reflectometry; GPS; Image analysis; Concrete structures; teknisk geografi; Hydrogeology;

   Sammanfattning : The Swedish hydropower industry operates a large number of power plants and dams geographically spread over the country. The level of safety of a specific dam is to a large extent determined during the design and construction phases that in the case of Swedish hydropower plants took place several decades ago. LÄS MER
