1. Odour recognition using electronic noses in robotic and intelligent systems
Sammanfattning : This thesis is about integrating the sense of smell into artificial intelligent systems. In order to endow such systems with olfaction, we use a device called an electronic nose or e-nose. LÄS MER
2. Direction-dependent processes - Theory and application
Sammanfattning : In this thesis, direction-dependent processes are described as processes whose responses differ in shape, strength and speed, depending on whether the input signal or output signal increases or decreases. The way in which these dynamics arise is discussed for three different applications; these applications are a thermomechanical pulp refiner, in which the motor load response to the hydraulic pressure is direction dependent, a paper machine, in which the calliper control in the calender section is direction dependent, and an electronic nose, in which the response to substrate concentration is direction dependent.

3. New Algorithms for General Sensors, or, How to Improve Electronic Noses
Sammanfattning : This thesis consists of three parts. The first part describes some new algorithms that we have invented for use in the field of sensor technology. Sensor technology is evolving rapidly and new sensors such as electronic noses and tongues have emerged on the market. LÄS MER
4. Data Evaluation for an Electronic Nose
Sammanfattning : An electronic nose is a device that tries to perform the same task as the human olfactory system, to be able to discriminate between different odours. In an electronic nose there are currently a number of individual sensors (typically 5-20). The response from a chemical sensor is usually measured as the change of some physical parameter, e.g. LÄS MER
5. Multivariate monitoring, modelling and control for stabilization of bioprocesses
Sammanfattning : The obstacles to overcome low reproducibility and stability of bioprocesses are numerous. Underlying biochemical processes are inherently non-linear, complex and subject to shifting initial conditions. Problems with high variability are also associated to production strains and scale-up of a bioprocess to largescale bioreactors. LÄS MER
