1. 6. Transport of non-spherical particles in pipeflow with suction

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Emil Wångby; [2020]
   Keywords : Brownian motion; Non-spherical particles; Pipe flow;

   Abstract : The interest of how small non-spherical particles transport behaviour when transported in pipe-flow is of large interest in a variety applications. This kind of theory have been used when studying composite manufacturing and how particles behaves in the human lungs. READ MORE

3. 7. Development and Implementation of a Mass Balancing System for CubeSat Attitude Hardware-in-the-Loop Simulations

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Guillermo Ledo López; [2019]
   Keywords : hil; hardware in the loop; simulation; satellite; simulator; platform; simulink; matlab; least squares; aocs; testing; attitude; dynamics; control;

   Abstract : Spacecraft simulator platforms can simulate the microgravity environment of space on Earth, for the purposes of testing the Attitude and Orbit Control Subsystem of satellites. In order to do this, the satellite is mounted on a bench and the combined center of mass of this assembly is controlled by a series of moving masses. READ MORE

4. 8. Developing a prototype using IMUs to do 24 hours measurement of knee joint mobility in children with Cerebral Palsy

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Anza Ahmed; [2019]
   Keywords : IMU; Biomedical engineering; sensors; cerebral palsy; CP; BNO055; BNO080; knee joint; Arduino; electrical engineering; Technology and Engineering;

   Abstract : Cerebral Palsy (CP) is a disorder of movement that is caused before, during or soon after birth. CP affects movement and co-ordination caused by lack of muscle control by the brain [1], [2]. Stiff muscles, weak muscles, tremors and seizures as well as difficulties with swallowing are examples of symptoms in children with CP. READ MORE

5. 9. Tool orientation estimation to control the angle tightening process of threaded joints

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

   Author : Max Thiel; [2019]
   Keywords : angle controlled tightening; tool orientation; extended kalman filter; particle filter; quaternions;

   Abstract : The most common method for securing components to each other during manufacturing of products is by joining these using screws, nuts and bolts. The benefit of using this method is that it is cheap and makes it easy to join and separate components quickly. READ MORE

6. 10. Orientation estimation and movement recognition using low cost sensors

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Álvaro López Revuelta; [2017]
   Keywords : signal processing; orientation estimation; quaternion; euler angles; rotation matrices;

   Abstract : Orientation estimation is a very well known topic in many fields such as in aerospace or robotics. However, the sensors used are usually very ex- pensive, heavy and big, which make them not suitable for IoT (Internet of Things) based applications. READ MORE
