1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. LÄS MER
2. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. LÄS MER
3. Virtual Sensing for Cluster Vacuum Control
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The purpose of this project was to develop a virtual sensing model in order to estimate the vacuum level in the milking cluster with data collected further along the milk tube. Measuring the cluster vacuum level is desirable for many applications, such as control and monitoring, but due to the cow's tendency to kick, chew and stomp on anything within reach, placing a sensor in or close to the cluster is both difficult and impractical.

4. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER
5. Characterization of NOx sensor performance under oscillating pressure conditions
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger.
