   Author : Malin Albing; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik inriktning industriell statistik;

   Abstract : This thesis presents contributions within the field of process capability analysis. Process capability analysis deals with how to assess the capability of processes. Based on process capability analysis one can determine how the process performs relative to its product requirements or specifications. READ MORE

   Abstract : Clearing of vegetation has left large areas of southern Wello (Ethiopia) at a high risk ofland degradation. In this study, the causes, extent and consequences of land degradationproblems are reviewed. To see land cover changes, aerial photographs from 1958 and1986 were compared with the help of a GIS procedure. READ MORE

7. 5. Analysis and Design of Software-Based Optimal PID Controllers

   Author : Olof Garpinger; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industry; PID control; software; optimization; load disturbance attenuation; robustness; noise sensitivity; trade-off plots; modeling; friction stir welding;

   Abstract : A large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller.
