   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rare earth metals; leaching; waste treatment; solvent extraction; Cyanex 923; florescent lamp waste; recycling;

   Sammanfattning : With the rapid advancement of technology, the demand for elements such as rare earth metals (REMs) has increased considerably during the last decade. Many countries are facing problems securing sustainable supplies, a fact acknowledged in many publications. LÄS MER

3. 7. Waste Textiles Bioprocessing to Ethanol and Biogas

   Författare :Azam Jeihanipour; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

   Sammanfattning : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. LÄS MER

4. 8. Modelling and controlling an offset lithographic printing process

   Författare :Cristofer Englund; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural networks; Self-organizing map; Data mining; Outlier detection; Committee; Multiple models; Colour print control; Image analysis; Bildanalys;

   Sammanfattning : The objective of this thesis is to provide methods for print quality enhancements in an offset lithographic printing proess. Various parameters characterising the print quality are recognised, however, in this work print quality is defined as the deviation of the amount of ink in a sample image from the reference print.

5. 9. Efficient MIMO Detection Methods

   Författare :Mirsad Čirkić; Erik G. Larsson; John Thompson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : For the past decades, the demand in transferring large amounts of data rapidly and reliably has been increasing drastically. One of the more promising techniques that can provide the desired performance is multiple-input multiple-output (MIMO) technology where multiple antennas are placed at both the transmitting and receiving side of the communication link.

7. 10. Hyperspectral Image Generation, Processing and Analysis

   Författare :Hamed Hamid Muhammed; Ewert Bengtsson; Tommy Lindell; Erkki Oja; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys; Image analysis; Bildanalys;

   Sammanfattning : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. LÄS MER
