  1. 1. 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. 2. An Approach For Cable Drum Structure Optimization

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Shahin Rastegar; Angélique Thulander Graore; [2022]
    Keywords : Cable drum; Finite Element Analysis; MATLAB; Steel Structure;

    Abstract : Performing optimization of structures is always of great interest. There are several different ways to optimize steel structures. Today, several companies are having difficulties with their cable drums during transport. Cable drums with full cable load become heavy and make it difficult to transport. READ MORE

  4. 3. Linear Programming Algorithms for Multi-commodity Flow Problems

    University essay from KTH/Fysik

    Author : Isaac Rosenberg Enquist; Phillip Sjögren; [2022]
    Keywords : Multi-commodity Flow Problem; Linear Programming; Linear Optimization; Simplex; Interior-point Method; Graph Theory; Optimization Theory; Transportation Problems;

    Abstract : A multi-commodity flow problem consists of moving several commodities from their respective sources to their sinks through a network where each edge has different costs and capacity constraints. This paper explores different linear programming algorithms and their performance regarding finding an optimal solution for multi-commodity flow problems. READ MORE

  5. 4. Learning the Forward Operator in Photon-Counting Computed Tomography

    University essay from KTH/Matematik (Avd.)

    Author : Emanuel Ström; [2021]
    Keywords : Photon-Counting; Computed Tomography; Spectral CT; Regularisation; Deep Learning; Fotonräknande; Datortomografi; Spektral CT; Regularisering; Djupinlärning;

    Abstract : Computed Tomography (CT) is a non-invasive x-ray imaging method capable of reconstructing highly detailed cross-sectional interior maps of an object. CT is used in a range of medical applications such as detection of skeletal fractures, organ trauma and artery calcification. READ MORE

  6. 5. Optimisation of flat dielectric lenses using an interior point method

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Jonatan Ek; [2021]
    Keywords : Lens; Permittivity; Optimisation; Interior Point Method; Wave Propagation;

    Abstract : This thesis aims to study how flat dielectric lenses can be designed. The usage of flat lenses is steadily increasing as they are smaller and less bulky than traditional convex lenses. Instead of a lens with a curved surface the permittivity in the lens is varied to achieve the same effect. READ MORE
