  1. 1. Developing an Automated System for Yeast Culture Cultivation and Control using Flow Cytometry

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Sara Magnusson; [2023]
    Nyckelord :Yeast; flow cytometry; applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Flow cytometry is a versatile tool for monitoring a microbial population at a single-cell level. Multiple parameters can be monitored based on the users’ requirements through the utilization of different dyes, biosensors etc. LÄS MER

  3. 2. Machine-vision-based Detection of Paper Roll Core Eccentricity : Fast and Robust On-Line Measurement Using Circular Hough Transform

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Erik Sehlstedt; [2022]
    Nyckelord :Eccentricity; Core eccentricity; Paper roll; Machine vision; Computer vision; Hough transform; Circular Hough transform; Defect detection; On-line measurement; Quality control;

    Sammanfattning : The field of computer vision offers tools that allow machines to derive meaningful infor-mation from video and images and consequently make decisions based on visual inputs. In the paper industry, implementation of machine vision (MV) can be used to automate and speed up processes that require visual inspection, particularly certain segments of quality control – one such application being detection and measurement of paper roll core eccentricity.

  4. 3. Evaluation of the Scott bond method and testing of out-of-plane properties of paperboard

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Joel Olsson; [2022]
    Nyckelord :;

    Sammanfattning : The through-thickness mechanical behavior of paperboard is fundamental for converting operations and many end-use situations of paper-based products. High quality and uniformity of the through-thickness properties is ensured during paperboard manufacturing by use of on-line and laboratory quality control methods. LÄS MER

  5. 4. Sensor fusion and fault diagnosticsin non-linear dynamical systems.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Albin Nilsson; [2020]
    Nyckelord :Fault detection and isolation; FDI; sensor fusion; nonlinear; four wheel drive; vehicle; kinematics; kalman filter; KF; EKF; parity relations;

    Sammanfattning : Sensors are highly essential components in most modern control systems and are used in increasingly complex ways to improve system precision and reliability. Since they are generally susceptible to faults it is common to perform on-line fault diagnostics on sensor data to verify nominal behavior. LÄS MER

  7. 5. Combined Control and Path Planning for a Micro Aerial Vehicle based on Non-linear MPC with Parametric Geometric Constraints

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Björn Lindqvist; [2019]
    Nyckelord :Non-linear MPC; MAV; Path Planning; Obstacle Avoidance; Robotics; UAV; MPC;

    Sammanfattning : Using robots to navigate through un-mapped environments, specially man-made infrastructures, for the purpose of exploration or inspection is a topic that has gathered a lot of interest in the last years. Micro Aerial Vehicles (MAV's) have the mobility and agility to move quickly and access hard-to-reach areas where ground robots would fail, but using MAV's for that purpose comes with its own set of problems since any collision with the environment results in a crash.
