  1. 1. 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.

  3. 2. Most efficient Inverse Kinematics algorithm for Quadruped models : Comparing FABRIK to CCD

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

    Author : Matilda Richardsson; [2022]
    Keywords : Inverse Kinematics; FABRIK; CCD; Quadrupeds; Computer Graphics;

    Abstract : This paper compares the two heuristic inverse kinematics methods: Forward And Backward Reaching Inverse Kinematics (FABRIK) and Cyclic Coordinate Descent (CCD) in the use cases concerning quadruped models. Unoptimised versions of the two algorithms were implemented into a game engine and evaluated on a quadruped model. READ MORE

  4. 3. An Empirical Study of Modern Portfolio Optimization

    University essay from KTH/Matematisk statistik

    Author : Erik Lagerström; Michael Magne Schrab; [2020]
    Keywords : Mean variance optimization; portfolio theory; asset allocation strategies; equal risk contribution; most diversified portfolio; empirical study; backtesting; Mean variance-optimering; portföljteori; allokeringsstrategier; equal risk contribution; most diversified portfolio; empirisk studie; historisk simulering;

    Abstract : Mean variance optimization has shortcomings making the strategy far from optimal from an investor’s perspective. The purpose of the study is to conduct an empirical investigation as to how modern methods of portfolio optimization address the shortcomings associated with mean variance optimization. READ MORE

  5. 4. Implementation of a Hardware Coordinate Wise Descend Algorithm with Maximum Likelihood Estimator for Use in mMTC Activity Detection

    University essay from Linköpings universitet/Datorteknik

    Author : Mikael Henriksson; [2020]
    Keywords : ASIC; 5G; Massive MIMO; Implementation; 28-nm FD-SOI; Coordinate Descent;

    Abstract : In this work, a coordinate wise descent algorithm is implemented which serves the purpose of estimating active users in a base station/client wireless communication setup. The implemented algorithm utilizes the sporadic nature of users, which is believed to be the norm with 5G Massive MIMO and Internet of Things, meaning that only a subset of all users are active simultaneously at any given time.
