1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

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

   Author : Jimmy Atterstig; [2024]
   Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

   Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

3. 2. Comparative Analysis of the Inverse Kinematics of a 6-DOF Manipulator : A Comparative Study of Inverse Kinematics for the 6-DOF Saab Seaeye eM1-7 Manipulator with Non-Conventional Wrist Configuration

   University essay from Linköpings universitet/Reglerteknik

   Author : Anton Larsson; Oskar Grönlund; [2023]
   Keywords : ;

   Abstract : This report presents various methods for solving the inverse kinematic problem for a non-conventional robotic manipulator with 6 degrees of freedom and discusses their respective advantages and disadvantages. Numerical methods, such as gradient descent, Gauss-Newton and Levenberg-Marquardt as well as heuristic methods such as Cyclic Coordinate Descent and Forward and Backward Reaching Inverse Kinematics are discussed and presented, while the numerical methods are implemented and tested in simulation.

4. 3. Evaluating the Practicality of Using a Kronecker-Factored Approximate Curvature Matrix in Newton's Method for Optimization in Neural Networks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Magnus Tornstad; [2020]
   Keywords : ;

   Abstract : For a long time, second-order optimization methods have been regarded as computationally inefficient and intractable for solving the optimization problem associated with deep learning. However, proposed in recent research is an adaptation of Newton's method for optimization in which the Hessian is approximated by a Kronecker-factored approximate curvature matrix, known as KFAC.

5. 4. Multilateration in Direct ShortRange Communications Networks : Utilising Basic Safety Messages and Received Signal Strength Ranging

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Andrew Galbraith; [2020]
   Keywords : DSRC; trilateration; multilateration; RSS; V2X;

   Abstract : Traditional satellite positioning systems have limited resolution and have proved inaccuratein areas such as urban canyons where signals are subject to bounce phenomena or indeed may be entirely unavailable. An alternative method of positioning is that of tri/multilateration, which uses known positions and distances from beacon points to locate a receiver. READ MORE

6. 5. Physically Inspired Optimization

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Emmanuel-Roosevelt D Costa; [2020]
   Keywords : Optimization; Particle Swarm Optimization; PSO; Levenberg-Marquardt algorithm; Gradient descent algorithm; Gauss-Newton algorithm; Linear Least Squares; System of Springs; Physics and Astronomy;

   Abstract : Optimization is the study of finding the best solution for a problem. The applications of this field ranges from finding the best routes for travelling to finding the ground state of physical systems. READ MORE
