1. 31. CALIBRATION OF CHROMATOGRAPHY MODELS

   Författare :Patrik Persson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

   Sammanfattning : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. LÄS MER

3. 32. Modelling Aspects of Wastewater Treatment Processes

   Författare :Ulf Jeppsson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

   Sammanfattning : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. LÄS MER

4. 33. The Quest for Robust Model Selection Methods in Linear Regression

   Författare :Prakash Borpatra Gohain; Magnus Jansson; K.V.S Hari; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model selection; information criterion; linear regression; sparsity; high dimensional; Electrical Engineering; Elektro- och systemteknik; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : A fundamental requirement in data analysis is fitting the data to a model that can be used for the purpose of prediction and knowledge discovery. A typical and favored approach is using a linear model that explains the relationship between the response and the independent variables. LÄS MER

5. 34. Embedded Systems and FPGAs for Implementation of Control Oriented Models, Applied to Combustion Engines

   Författare :Carl Wilhelmsson; Förbränningsmotorer; []
   Nyckelord :NOx; NO; Nitrogen Oxides; Emissions; Air pollution; Algorithms; Physical model; Mathematical model; FPGA; Field Programmable Gate Arrays; Embedded Systems; Micro-controllers; Engine; Diesel Engine; Internal Combustion Engine; Combustion Control; Engine Control.;

   Sammanfattning : Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. LÄS MER

7. 35. Solid waste management based on cost-benefit analysis using the WAMED model

   Författare :Viacheslav Mutavchi; Jan Stenis; William Hogland; Torleif Bramryd; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic models; economic incentives; solid waste management SWM schemes; baling economics; municipal solid waste MSW management; ecological– economic efficiency ECO-EE ; cost-benefit analysis CBA ; full cost accounting FCA analysis; the WAMED model; the COSTBUSTER model; the EUROPE model.; Environmental technology; Miljöteknik; Business administration; Företagsekonomi;

   Sammanfattning : Efficient waste management enables the protection of human health, reducing environmental pollution, saving of natural resources, and achieving sustainable and profitable management of energy. In many countries, the general guidelines for waste management are set by national or local waste management plans. LÄS MER
