1. 1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Lisa Linard Pedersen; [2024]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

3. 2. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Nils Engman; [2023]
   Keywords : Sensors; IoT; Heat Exchangers; Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. Virtual Sensing for Cluster Vacuum Control

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Carl Egenäs; Axel Sacilotto; [2023]
   Keywords : ;

   Abstract : 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.

5. 4. Characterization of NOx sensor performance under oscillating pressure conditions

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Álvaro López Méndez; [2023]
   Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

   Abstract : 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. READ MORE

6. 5. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jennifer Ly; [2023]
   Keywords : Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

   Abstract : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.
