1. 1. Evaluation of pretension losses in heated screw joint

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Joel Svensson; [2022]
   Keywords : screw joint; clamping force; thermal load;

   Abstract : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. READ MORE

3. 2. An Investigation of Methods for Flow Measurements in a Gasketed Plate Heat Exchanger for Predictive Maintenance

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Viktor Ekström; [2022]
   Keywords : gasketed plate heat exchanger; electrical measurements; sensors; predictive maintenance; machine learning; Technology and Engineering;

   Abstract : For a company to stay relevant in the long term, it is essential to keep up with the latest technology and continuously consider new innovative solutions for improving products and services. The gasketed plate heat exchanger (GPHE) is a mechanical device, and this work attempts to investigate different possibilities for incorporating sensor devices and predictive maintenance systems to improve the device.

4. 3. Viscosity control of solder paste by ultrasound actuation

   University essay from KTH/Mekatronik

   Author : Erik Landman; [2018]
   Keywords : ;

   Abstract : The thixotropic characteristics of solder paste are an obstacle in improving the consistency with which solder paste droplets can be deposited by jet printers. Controlling the viscosity of solder paste may be an important step in improving the deposition. READ MORE

5. 4. Non-invasive ultrasound measurements of vascular impedance

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Roger Larsson; [2018]
   Keywords : Ultrasound; ultrafast ultrasound imaging; vascular impedance; pulse wave velocity; motion tracking; Technology and Engineering;

   Abstract : Despite its introduction in the early 1950´s, vascular impedance has yet to be applied in clinical use to predict early stages of cardiovascular disease (CVD). It is defined as the ratio between blood pressure and flow and describes the opposition to blood flow within the cardiovascular system. READ MORE

6. 5. Non-Invasive Liquid Metering Method Analysis

   University essay from KTH/Mekatronik

   Author : Gustav Sten; Thibault Helle; [2018]
   Keywords : ultrasonic; liquid; metering; non-invasive; ultraljud; flöde; vätska; icke-invasiv;

   Abstract : The ability to measure flow in pipes often introduces expensive and difficult installations due to existing flow-meters being invasive. To solve this a non-invasive solution has been found by testing and evaluating different mechanical and electrical methods using ultrasonic piezo-crystals and time-of-flight calculations. READ MORE
