1. 6. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Elvira Niemelä; [2022]
   Keywords : Permanent Magnet Synchronous Machine; Permanent Magnet Temperature Estimation; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer; Permanentmagnetiserad Synkronmaskin; Temperaturestimering för Permanentmagneter; Lumped Parameter Thermal Network; Dual Kalman Filter; Dual Observer;

   Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

3. 7. Risk Measurement and Performance Attribution for IRS Portfolios Using a Generalized Optimization Method for Term Structure Estimation

   University essay from Linköpings universitet/Produktionsekonomi

   Author : Fredrik Gerdin Börjesson; Christoffer Eduards; [2021]
   Keywords : Interest rate measurement; term structures; multiple yield curves; principal component analysis; systematic risk; risk factors; term structure simulation; Latin hypercube sampling with dependence; risk measurement; value-at-risk; expected shortfall; interest rate swap; performance attribution;

   Abstract : With the substantial size of the interest rate markets, the importance of accurate pricing, risk measurement and performance attribution can not be understated. However, the models used on the markets often have underlying issues with capturing the market's fundamental behavior. READ MORE

4. 8. Evaluation of a new point-of-care test for measuring proenkephalin in blood as an estimate of kidney function

   University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

   Author : Sara Häggmark; [2021]
   Keywords : PENK; glomerular filtration rate; iohexol plasma clearance; creatinine; cystatin C;

   Abstract : Background: Glomerular filtration rate (GFR) is a clinically important measurement of kidney function and estimating the GFR is of great importance in healthcare. Methods available today either lack in precision or are overly time consuming. READ MORE

5. 9. New Measurement Methods For Ground Vibration Test

   University essay from KTH/Flygdynamik

   Author : Hugo Perez; [2020]
   Keywords : ;

   Abstract : Flight-testing represents an important step of an airplane development. Every new or modified aircraft configuration is tested. Through set of tests, the quality and reliability of aircrafts are guaranteed. At Dassault Aviation, the flight test Directorate responsible for carrying out flight tests is located at Istres, in South of France. READ MORE

6. 10. Material parameter identification of a thermoplastic using full-field calibration

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Nikhil Prabhu; [2020]
   Keywords : DIC; FFC; Thermoplastics; Material parameter identification; multi-point history; Polyamide 6; GISSMO; Response Surface Methodology;

   Abstract : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. READ MORE
