1. 1. A two step model for linear prediction, with connections to PLS

   Författare :Ying Li; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In the thesis, we consider prediction of a univariate response variable, especially when the explanatory variables are almost collinear. A two step approach has been proposed. The first step is to summarize the information in the explanatory variables via a bilinear model with a Krylov structured design matrix. LÄS MER

3. 2. Preliminary estimation of transfer function weights : a two-step regression approach

   Författare :Per-Olov Edlund; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : In economic time series modelling, dynamic relationships frequently have to be modelled where the explanatory variables influence the dependent variable over more than one period. Such dynamic relationships are found in business cycle forecasting with leading indicators, in marketing models describing the relationship between advertising and sales, and in many traditional econometric models.

5. 4. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts

   Författare :Bo Wei; Reza Fakhrai; Torsten Fransson; Nader Jand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conversion; solar; ceria; thermogravimetric test; exergy analysis; simulink; fluidized bed; gas-solid flow; simulation; Energiteknik; Energy Technology;

   Sammanfattning : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. LÄS MER

7. 5. Design and Analysis of Diagnosis Systems Using Structural Methods

   Författare :Mattias Krysander; Mattias Nyberg; Jan Lunze; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diagnosis; graph theory; structual methods; algorithms; fault isolation; complete; sound; Systems engineering; Systemteknik;

   Sammanfattning : In complex and automated technological processes the effects of a fault can quickly propagate and lead to degradation of process performance or even worse to a catastrophic failure. This means that faults have to be found as quickly as possible and decisions have to be made to stop the propagation of their effects and to minimize process performance degradation. LÄS MER
