  1. 1. Server-side factor graph optimization for on-manifold pre-integration in IoT sensors

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Samuel Gradén; [2023]
    Keywords : Edge computing; IoT; optimization; tracking; drone;

    Abstract : State and specifically location estimation is a core concept in automation and is a well-researched field. One such estimation technique is Moving Horizon Estimation (MHE). In this thesis, the MHE variant single-shooting estimation will estimate the location and velocity of a moving object. READ MORE

  3. 2. Does attentional focus influence performance and motor control on a gross motor task performed with the legs among healthy individuals and individuals with anterior cruciate ligament reconstruction? : A within subject design pilot study

    University essay from Umeå universitet/Institutionen för samhällsmedicin och rehabilitering

    Author : Leon Haegerström; Jens Jakobsson; [2023]
    Keywords : Attentional focus; External focus; Internal focus; Motor contor; Motor performance; Anterior cruciate ligament reconstruction;

    Abstract : Background: Evidence indicates that an external focus (EF) of attention on the intended effect of one’s movement results in better motor performance and motor control than an internal focus (IF) on one’s own body. Despite this, an IF is predominantly encouraged through instructions and feedback provided by clinicians during sports and rehabilitation from injuries such as anterior cruciate ligament (ACL) injury.

  4. 3. Phase Unwrapping MRI Flow Measurements

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Mio Liljeblad; [2023]
    Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

  5. 4. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

    University essay from KTH/Ergonomi

    Author : Mohammed Abderhman Abaid; [2023]
    Keywords : Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

    Abstract : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. READ MORE

  6. 5. Adaptive Control of a Permanent Magnet Synchronous Motor for a Robotic Arm under Variable Load

    University essay from KTH/Mekatronik och inbyggda styrsystem

    Author : Anton Haga Lööf; [2023]
    Keywords : Mechatronics; PMSM; Model Based Control Theory; Adaptive; Automation; Estimation; Mekatronik; PMSM; Modellbaserad Reglerteknik; Adaptiv; Estimering;

    Abstract : The implementation of automated systems in manufacturing industries increases efficiency, precision, and safety by reducing human intervention, errors, and waste. Variable loads can cause several problems for automation systems. READ MORE
